MARKET SUMMARY

MDX has been very important to Acura, accounting for about 30-percent of the division's overall sales. The original MDX attracted buyers from competitive luxury makes including BMW, Mercedes-Benz and Lexus, who started new relationships for Acura. The 2010 MDX competes at the top of its class that is defined as the Mid Premium CUV (Crossover Utility Vehicle) segment.

TARGET CUSTOMER

Focus groups with customers shopping in the luxury market were conducted around the United States with an increased focus in Seattle, Detroit, Chicago and Los Angeles. These cities were carefully chosen to explore how customers use their SUVs in cold climates, in areas that are traditional domestic-vehicle strongholds and in areas known for their trend-setting character.

Early in the study process Acura also benchmarked performance SUVs such as the BMW X5 - and polled X5 owners - to ensure that the MDX would exceed the performance of its competitors. Satisfying these highly discriminating customers means that the MDX would be well positioned to attract a wider group of potential buyers.

With the MDX, added performance and handling capabilities boost its appeal for performance enthusiasts, while the luxurious and functional interior continues to satisfy the needs of traditional luxury customers.

ENGINE & POWERTRAIN

For 2010 the MDX's receives a new 3.7-liter VTEC® V-6. The engine continues Acura's longstanding mission to provide V-8 level horsepower and torque while retaining the size and fuel efficiency of a V-6. Based on the previous MDX's powerplant, the new 3.7L engine develops 300 horsepower and 270 lb-ft of torque along with providing immediate acceleration response, outstanding low- and mid-range torque and exciting high-rpm power. To widen the powerband while simultaneously improving fuel efficiency, the 3.7-liter engine has a new 2-rocker arm design VTEC® (Variable Valve Timing and Lift Electronic Control) system applied to the intake valves, revised high-lift camshaft specs during VTEC® operation, a computer controlled dual-stage induction system and an electronic Drive-by-Wire™ throttle system.

EPA estimated city/highway fuel economy of 16/21 mpg and a large 21-gallon fuel capacity mean the MDX has a long cruising range. The MDX complies with the latest EPA TIER 2 - BIN 5 and CARB LEV II ULEV emissions standards. Performance and fuel economy benefit from the MDX's all-new 6-speed automatic transmission, and the transmission's quick-response Sequential SportShift function is designed to satisfy the most discerning enthusiast drivers.

Originally tuned on the famed Nürburgring circuit in Germany, the MDX's Super Handling All-Wheel Drive™ (SH-AWD®) system provides handling precision that sets a new benchmark for SUVs. SH-AWD® uses torque vectoring to actively vary the distribution of power between the front and rear axles - then between the left and right rear wheels - to provide maximum power delivery under all driving circumstances. In addition to the torque vectoring, SH-AWD® overdrives the outside rear wheel up to 1.7 percent faster than the front wheels to create a "yaw moment" that helps the MDX to better rotate around a corner - thus minimizing understeer.

BODY & CHASSIS

The 2010 MDX sets even higher standards for SUV styling, engineering, handling and safety standpoints. Its dramatic exterior styling utilizes large surface areas, sweeping curves and decisive angles. New for 2010 are more aggressive front and rear fascias, Acura's signature front grille, a revised front hood, new side sills, rolled edge polished stainless-steel exhaust finishers, revised taillights with brighter LED lights and numerous new trim pieces.

In an effort to keep mass out of the vehicle, the MDX features widespread use of light weight materials such as high-strength steel, aluminum and magnesium. In addition, the Advanced Compatibility Engineering™ (ACE™) body structure brings new levels of front crash safety to the MDX.

Befitting its position as Acura's flagship SUV, the MDX is equipped with high end appointments such as Xenon High-Intensity Discharge (HID) low-beam front headlights, a dramatic array of Light Emitting Diodes (LEDs) in the rear tail lamps and center high-mounted stop light (CHMSL) and exterior mirror-mounted turn signals. Careful aerodynamic tailoring reduces drag noise and high speed dynamic stability.

The 2010 MDX features a track-tuned chassis to complement its new 3.7L V-6 engine and Super Handling All-Wheel Drive™ (SH-AWD®). Engineers targeted the BMW X5 and Porsche Cayenne when developing the MDX chassis, and then tested and refined it at Germany's famed Nürburgring road course. The Active Damper System has been revised for 2010 and features real-time shock adjustments (in less than five milliseconds) ­to continually varying road conditions. The Active Damper System uses highly sophisticated Magneto-Rheological design dampers and specific computer algorithms to quickly and continuously adapt to road conditions. The MDX is also at home off-road where its SH-AWD®, responsive suspension and generous ground clearance enable it to cross-step through rough terrain.

For family recreation, the MDX tows as well as it goes. With a 5,000-pound tow rating, standard trailer pre-wiring, high-capacity radiator with twin cooling fans, transmission fluid cooler and Trailer Stability Assist, the 2010 MDX needs only a dealer-installed hitch and wiring to tow a trailer.

INTERIOR

The MDX features a luxurious yet functional interior. The cockpit environment is focused on the driver, and features a host of technologies to make driving simultaneously rewarding and relaxing. The interior styling and functionality perfectly coexist with a driver's cockpit that features a 10-way power seat including power-adjustable lumbar support for the driver, electronic tilt and telescoping steering column, a 2-position custom memory system, and a Multi-Information Display (MID) that allows access to multiple electronic functions.

The interior design is as dynamic and contemporary as the exterior, with a "4+3 seating" concept that luxuriously hosts four passengers in the first and second row seats, while also offering comfortable accommodations for three additional passengers (one in the second row and two in the third row). The front passenger enjoys an 8-way power seat, while everyone on board will appreciate the MDX's Tri-Zone automatic climate control system. MDX occupants will enjoy the standard 253-watt, 8-speaker Acura Premium Sound System with in-dash 6-disc CD/MP3/WMA changer, AM/FM tuner and XM® Radio. An auxiliary jack for personal audio devices is also included. Standard convenience features include HomeLink®, Maintenance Minder™ and adaptive and flexible cargo space with six configurations.

All 2010 MDX models come standard with a rearview camera. The standard MDX displays the rearview image on a new auto-dimming rearview mirror with integrated video screen, while the Technology Package and Advance Package displays multi-view camera information on the instrument panel-mounted Navigation screen. When equipped with the Advance Package, a blind spot information system can detect other vehicles when they are in the blind spot of the MDX driver. The MDX has a 5,000-pound tow rating and can be fitted with a Class III hitch, as well as over a dozen other items from Acura Genuine Accessories.

SAFETY

The Advanced Compatibility Engineering™ (ACE™) body structure along with several passive-safety technologies help bring the 2010 MDX to the next level of safety. ACE™ more evenly distributes collision forces and helps maintain the integrity of the passenger cabin in the event of a severe frontal collision. The MDX is also less intrusive to smaller vehicles in a head-on collision thanks to a special frame member located below the front bumper that is designed to engage the front bumper of smaller vehicles.

The MDX is equipped with an active front head restraint system for front seat headrests along with knee bolsters for the driver and front passenger. The driver and front passenger are also protected by dual-stage, multiple-threshold airbag Supplemental Restraint System (SRS) and side airbags with front passenger Occupant Position Detection System (OPDS). Side curtain airbags help reduce the likelihood of injury to the occupants in all three rows of outboard seats A new rollover sensor adds a further level of protection.

The 2010 Acura MDX furthers Acura's commitment to "Safety Through Innovation" with pedestrian injury mitigation features such as a deformable aluminum hood and hood hinges, along with breakaway windshield-wiper pivots.

MANUFACTURING & ENVIRONMENT

Honda of Canada Manufacturing in Alliston, Ontario, is the assembly plant for the MDX. A special dynamic quality-control process is employed to ensure the highest possible level of attention to detail for every MDX produced. After assembly is completed, each MDX enters a special Acura Quality line. The ability to immediately respond to the smallest issue allows the MDX to excel in quality - and in customer satisfaction.

Acura's commitment to preserving the environment continues with the MDX via further reduction of the use of metals such as chromium and lead, volatile organic compounds (VOCs) and polyvinyl chlorides (PVC). In the manufacturing facility, a dedicated line separates different manufacturing scrap materials for recycling. In addition, the MDX is the first Acura vehicle to use a mercury-free navigation system display screen.

2010 Acura MDX - Powertrain

To deliver a seamless blend of power, refinement and efficiency, the MDX features the latest-generation Acura 3.7-liter VTEC® V-6 engine. As large as any engine in the Acura product line, the all-aluminum powerplant has single overhead camshaft cylinder heads and 24 valves, with the intake valves actuated by Acura's acclaimed VTEC® (Variable Valve Timing and Lift Electronic Control®) system. The compact and efficient engine produces 300 horsepower and 270 lbs-ft of torque, with special emphasis on mid-range torque for outstanding overall driving character.

The MDX's evolved 3.7L V-6 uses a more rigid cylinder block, high-strength crankshaft, heavy-duty connecting rods, high compression-ratio pistons, cylinder heads with improved cooling, exclusive camshaft specs, a new 2-rocker arm design VTEC® valvetrain system, more performance oriented camshaft specs when in VTEC®, new intake valve springs, a new EGR system, unique long-reach spark plugs, a larger throttle body among other features.

The engine reflects Acura's unwavering commitment to the environment with excellent fuel efficiency given its power output. The MDX achieves an EPA rated city/highway fuel economy of 16/21 mpg*- which give it a best-in-class combination of fuel economy and power. For all its performance, the MDX's V-6 is also very clean as it meets EPA TIER 2-BIN 5 and CARB LEV II ULEV emission standards, and it has close-coupled catalytic converters to ensure efficient cold-start emissions control.

The 3.7L V-6 is coupled with a brand-new Sequential SportShift 6-speed automatic transmission along with a new multi-clutch torque converter. With comparatively "short" gearing in the first five forward gears, acceleration is enhanced- while fuel economy and quiet cruising are optimized with a relaxed Sixth gear ratio. The transmission offers two automatic shift modes, or can be operated manually via racing-inspired steering wheel paddle shifters. Grade Logic Control, Shift Hold Control and Cornering G Shift Control make the new 6-speed the most advanced automatic transmission ever offered by Acura.

The 2010 MDX features Super Handling All-Wheel Drive™ (SH-AWD®), Acura's advanced drivetrain system that delivers quick, precise all-wheel-drive response. SH-AWD® distributes the optimum amount of torque not only between the front and rear axles, but also between the left and right rear wheels. The system's unique "torque vectoring" direct yaw control feature helps make the MDX exceptionally neutral handling under power, for greater handling precision and control. Along with its dry-pavement handling advantages, the MDX's SH-AWD® system also offers excellent all-season capability and requires no driver intervention to operate.

ENGINE ARCHITECTURE

The MDX's 3.7-liter V-6 engine employs an inherently smooth-running 60-degree V-angle. The cylinder block is constructed of aluminum and has high-silicon aluminum cylinder liners for added weight savings and excellent cooling. The cylinder heads are cast of lightweight aluminum and feature four valves per cylinder along with a VTEC® variable valve timing system with variable lift and timing for the intake valves. Power is enhanced with a higher 11.2:1 compression ratio, high-output port designs, intake airflow optimization and a sport-tuned exhaust system. In addition to a high power output, the 3.7-liter V-6 delivers good fuel economy and low emissions.

ENGINE BLOCK

The engine block of the 3.7-liter MDX is constructed of lightweight die-cast aluminum. The cylinder liners are made of high-silicon aluminum and are cast directly into the aluminum block. The hard piston ring sealing surface of the liners is created during manufacturing with a mechanical etching process that exposes silicon particles embedded in the sleeves. The aluminum sleeves provide better cooling, thus allowing closer piston-to-cylinder clearance than iron liners afford.

The cylinder block is heat-treated for strength and has a deep-skirt design with four bolts per bearing cap (providing excellent structural support for the crankshaft), thus minimizing engine noise and vibration. The MDX uses the latest version of the 3.7L V-6 that features improved cylinder-block rigidity and stronger/stiffer mounting points that team to further reduce NVH.

CRANKSHAFT/CONNECTING RODS/PISTONS

The MDX's 3.7L V-6 engine employs a crankshaft that features higher quality (and subsequently stronger) forged steel for improved strength. New 11.2:1 compression ratio forged aluminum pistons replace the previous 3.7L's 11.0:1 pistons, and the pistons are cooled with oil spray directed up to the underside of the piston crowns, helping make possible the high compression ratio. In addition, the pistons feature a new 2-piece oil ring assembly that improves durability. Just as with the previous 3.7L, the connecting rods are steel forgings for high strength, but the latest version of the rods feature a wider beam width for improved strength. A unique "crack separated" build process (in which the bearing caps are broken away from the rod rather than machined separately) allows for a lighter, stronger connecting rod with perfect mating surfaces.

CYLINDER HEADS/VALVES

The 3.7-liter engine has lightweight aluminum cylinder heads that are pressure cast for high accuracy and low porosity. Each cylinder head uses a single camshaft, turned by an Aramid-fiber reinforced toothed belt drive for long service life. To save weight and reduce parts count, the cylinder heads have uniquely integrated exhaust-port castings that provide optimal positioning of the close-coupled catalytic converters- one on each cylinder bank. This design results in more rapid "light off" of the catalytic converters during cold start-up for reduced emissions. Unique long-reach spark plugs are now used in the cylinder heads that promote improved combustion for lower emissions and improved mid-range torque.

The cylinder-head castings feature port flow optimization for improved performance, while an upgraded water pump teams with revised cylinder head coolant flow for improved cooling performance. Upgraded intake valve springs are used to match the revised camshaft specs for the intake valves during VTEC® operation. The cylinder heads are sealed against the block with a new 3-layer, shim-type head gasket.

VTEC® (VARIABLE TIMING AND LIFT ELECTRONIC CONTROL)

The MDX engine uses the VTEC® system, providing strong low-speed torque, crisp throttle response, and enhanced high-rpm power. This is achieved by providing reduced intake valve lift and duration at low engine speeds for good torque, with increased intake valve lift and duration at higher rpm for optimum power.

The MDX features a new 2-arm version of the Acura VTEC® rocker arm system that provides 2-mode control of the intake valves. Variable operation of the engine's intake valves are controlled for optimal volumetric efficiency, air/fuel mixing, burn rate and exhaust flow. The 2-arm VTEC® rocker arm design offers less overall mass and has roller arm tips to reduce operating friction.

At 4,800 rpm, the Powertrain Control Module (PCM) electronically triggers the opening of a spool valve that routes pressurized oil to small pistons within the intake valve rocker arms. Moved by this pressurized oil, the pistons lock each cylinder's pair of intake rocker arms together. The linked intake rockers then follow a single high-lift, long-duration cam lobe- an intake lobe with more lift and duration than used with the previous 3.7L V-6. The VTEC® high-lift mode increases intake valve lift by 28-percent and valve opening duration by 35-percent-an increase of 5- and 3-percent (respectively) versus the 3.7L V-6 engine used in the 2009 MDX.

To maintain the MDX's refined operating characteristics, careful intake and exhaust helps to make the VTEC® changeover smoother and quieter for a seamless driving experience that's nearly undetectable to the driver and passengers.

DRIVE-BY-WIRE™ THROTTLE SYSTEM

The MDX does not use a conventional mechanical throttle linkage, but instead employs sophisticated electronics to provide the connection between the throttle pedal and the engine's throttle-body. The result is more accurate and precise throttle control, along with less clutter and reduced weight under the hood. By programming such factors as "gain" and "tip-in" into the throttle actuation, engine response and drivability can be tailored to suit specific driving conditions.

Acura's Drive-by-Wire™ throttle system monitors pedal position, throttle-body opening, engine rpm, and road speed to establish driving conditions in real time. This data is used to define the throttle control sensitivity necessary to provide the predictable and responsive feel corresponding to driver expectations.

The Drive-by-Wire™ throttle system also helps integrate engine functions with the Vehicle Stability Assist™ (VSA®) and traction control system. To smooth downshifts, the system is programmed to "blip" the throttle to help match engine speed to gear speed within the all-new Sequential SportShift 6-speed automatic transmission.

PROGRAMMED FUEL INJECTION (PGM-FI)

The Programmed Fuel Injection (PGM-FI) system continuously tracks many engine parameters including crankshaft and camshaft positions, throttle position, intake air temperature and mass flow rate, engine coolant temperature and manifold pressure-and then the PGM-FI system adjusts fuel delivery accordingly to deliver the best combination of power, fuel economy and low emissions.

MULTI-HOLE FUEL INJECTORS

Special multi-hole fuel injectors mounted in the lower intake manifold spray directly toward the intake ports. The multi-hole injector design means that fuel droplet size is reduced for better fuel atomization, resulting in improved cold weather start-up, better fuel economy, lower emissions and higher horsepower.

2-PIECE DUAL-STAGE INTAKE MANIFOLD

The MDX features a dual-stage intake manifold made from lightweight magnesium-alloy. The manifold works together with VTEC® to improve low-speed torque with no sacrifice in high-rpm power. Divided into two banks feeding three cylinders per bank, the manifold has two Powertrain Control Module-controlled butterfly valves located between each bank. These closed valves separate bank-to-bank plenum chamber and improves the resonance charge effect. The result is an amplification of pressure waves within each half of the manifold at lower engine speeds, improving low rpm torque. The open ends of the intake runners are also flared into a "trumpet" shape (as on racing engines) to further improve airflow.

The butterfly valves open above 4,050 rpm, connecting the two halves of the intake manifold, increasing its effective volume. The manifold's two modes further complement the changes in low and high rpm running made possible by the VTEC® system.

DIRECT IGNITION AND DETONATION-KNOCK CONTROL

Because accurate ignition spark timing is crucial for best power and torque output as well as reduced emissions, the Powertrain Control Module (PCM) continually monitors several engine parameters to determine optimum spark timing for all driving conditions.

A strong ignition spark is critical to improve power and reduce emissions. Thus, the new 3.7L V-6 employs coil-on-plug design ignition coils and special long-reach spark plugs. Additionally, a block-mounted acoustic detonation (knock) sensor "listens" to the engine, sending information about potentially damaging detonation to the PCM, which then incrementally retards ignition timing to help prevent damage. Individual coil units positioned directly above each iridium alloy-tipped spark plug compliment the ignition system. The spark plugs require no scheduled service prior to 100,000 miles of use. To help improve misfire detection, the new 3.7L V-6 uses a new high-resolution crankshaft pulser that generates more accurate timing information.

HIGH-FLOW EXHAUST SYSTEM WITH CLOSE-COUPLED CATALYTIC CONVERTERS

The MDX's 3.7-liter engine has exhaust manifolds that are cast directly into the cylinder heads for lighter weight, reduced parts count and less bulk. Attached directly to the cylinder heads are high-efficiency, free-flowing 600-cell catalytic converters. Due to closer-than-normal proximity to the exhaust ports, the close-coupled catalytic converters "light off" very quickly after the engine starts, better reducing emissions in the critical start-up mode. To ensure optimum flow and low backpressure, a hydroformed two-into-one collector connects the close-coupled catalytic converters to the main 350-cell under-floor catalytic converter.

The MDX's high-flow exhaust system splits just past the under-floor catalytic converter. To provide clearance for the all-wheel-drive system's rear-mounted differential, one exhaust pipe is routed on each side of the driveshaft and feeds into a high-flow silencer on each side of the MDX. In addition, for 2010 the exhaust pre-chambers have been moved up closer to the MDX underbody to provide added ground clearance and improved looks (the chambers are now far less visible). Dual exhaust outlets, one on each side, are integrated into polished stainless-steel (laser welded) finishers positioned in the rear fascia. For corrosion resistance, the entire exhaust system (including pipes, silencers, chambers and hanger rods) is constructed of stainless steel.

EMISSIONS CONTROL

The MDX meets EPA TIER 2-BIN 5 and CARB LEV II ULEV emission standards, and is certified to this stringent standard for 120,000 miles of service.

Acura's advanced technologies contributing to this performance are the close-coupled catalytic converters which light-off quickly on start-up and a high amount of EGR gas recirculated into the engine.

The engine features Programmed Fuel Injection (PGM-FI) that continually adjusts fuel delivery to achieve the best combination of power, fuel mileage and low emissions. Particularly in the critical post-startup mode, the high-efficiency multi-hole fuel injectors deliver better fuel atomization for lower emissions.

ONE-TOUCH STARTER SYSTEM WITH HIGH-POWERED STARTER

The MDX engine features a high-powered starter to crank the engine. In addition, it employs a one-touch system that automatically maintains starter engagement until the engine has started. The driver simply turns the key, and without having to hold it for any extended time, the one-touch system cranks the starter until the engine fires up and then disengages the starter automatically.

NOISE, VIBRATION AND HARSHNESS (NVH) CONTROL

The MDX powertrain is designed to effectively control Noise, Vibration and Harshness (NVH). Cylinders with a 60-degree V-angle, a high-rigidity die-cast engine block, strong forged-steel crankshaft, die-cast accessory mounts and stiff cast aluminum engine oil pan, all work together to ensure low engine NVH. Electronically Controlled Mounts (ECM) at the front of the transversely oriented engine block has two firmness settings-softer at low speeds (for improved comfort) and firmer (for improved performance) as engine speed rises.

100,000-MILE TUNE-UP INTERVAL

The MDX is an exceptionally low-maintenance vehicle. With features like Iridium alloy-tipped spark plugs and a space-saving, self-tensioning serpentine accessory drive belt, the engine requires no scheduled maintenance until 100,000 miles- with the exception of periodic inspections and normal replacement of fluids and filters. The first scheduled tune-up at 100,000 miles includes valve adjustment, timing belt replacement and water-pump inspection. Exact mileage for engine service is determined by actual driving conditions.

MAINTENANCE MINDER™

The MDX has a Maintenance Minder™ system to monitor operating conditions and to alert the driver should maintenance be required. When the ignition is first turned on, the Multi-Information Display (MID) located between the tachometer and speedometer shows maintenance information, if required. To avoid driver distraction, the display is not shown while driving. The MID indicates the remaining percentage of engine oil life, and indicates when service is due with a "wrench" icon. A percentage-based countdown to the next service is displayed when the car is within 15-percent of the end of the service interval. The type of service required is shown in an alphanumeric code, and if a service is missed, the MID indicates its urgency by showing past-due mileage.

The owner-resettable system monitors all normal service parts and systems including engine oil, oil filter, tire rotation, air cleaner, automatic transmission fluid, rear differential fluid, spark plugs, timing belt and coolant. The system is designed to eliminate unnecessary maintenance, reduce environmental impact and expenses as well as to ensure long component and vehicle life.

SEQUENTIAL SPORTSHIFT 6-SPEED AUTOMATIC TRANSMISSION

To maximize driver control, acceleration and fuel economy, the MDX is equipped with an all-new 6-speed automatic transmission featuring Sequential SportShift with racing-inspired steering wheel mounted paddle shifters and two automatic shift modes.

Though comparable in size and weight to Acura's existing 5-speed automatic transmissions for V-6 engines, careful engineering of the layout and power flow minimizes size, parts count and overall weight.

The new Sequential SportShift 6-speed automatic advances launch-feel, acceleration performance and fuel efficiency. Compared to the 5-speed transmissions used with other V-6 engines in the Acura line, the MDX has lower gear ratios (higher numerically) in First through Fifth gears and in Reverse. The lower gear ratios improve acceleration and pulling power. The new Sixth gear ratio is taller (lower numerically) than the top gear in Acura's 5-speed V-6 automatic transmissions. The taller final gear allows for a relaxed cruising rpm and enhanced highway fuel economy.

The new 6-speed automatic transmission also includes engineering enhancements aimed at improved performance and economy. Expanded multi-disc lock-up control improves the efficiency of power delivery and works with the new gear ratios to provide a 1.0 mpg improvement in fuel economy on the highway, and a 0.8 mpg improvement in city driving, as compared to a conventional design.

The 6-speed transmission is controlled by either the straight-gate console-mounted shifter or a "smart" steering wheel paddle shifter system that also works whenever the transmission is in either of its two automatic modes. The transmission features an expanded complement of smart logic controls. In addition to Grade Logic Control and Shift Hold control, the MDX also now has Cornering G Shift Control. All of the transmission logic systems work together to automatically alter shift timing based on driving conditions.

Automatic Modes
The Sequential SportShift 6-speed transmission can be operated in two different fully automatic modes with the console-mounted straight-gate shifter. The D, or "Drive", mode is ideal for most driving situations, and combines fuel efficiency with smooth operation and responsive power when needed. The S, or "Sport", mode is for more performance-oriented driving, and features aggressive shift mapping to keep engine rpm higher for greater acceleration and response. In Sport mode the transmission typically operates in the four lowest gears, and won't shift to Fifth gear unless the vehicle reaches very high speed. In Sport mode, the economy-oriented Sixth gear is locked out.

When in the D mode (that is optimized for normal driving), the transmission incorporates an advanced Grade Logic Control System, Shift Hold Control and Cornering G Shift Control-all of which reduce unwanted shifting and gear hunting. The result is smart transmission operation that optimizes fuel efficiency and keeps the transmission in the appropriate gear for the specific driving conditions, thus generating excellent performance and smooth operation.

While traveling up or down hills, Grade Logic Control alters the transmission's shift schedule to reduce shift frequency and improve speed control. A shift map in the transmission computer continually measures throttle position, vehicle speed and acceleration/deceleration, and then determines when the vehicle is on a hill. The shift schedule is then adjusted to hold the transmission in lower gears to boost climbing power or to provide engine braking when traveling downhill.

Shift Hold Control keeps the transmission in its current (lower) gear ratio when aggressive driving is detected, as in the case of decelerating at a corner entry. Shift Hold Control leaves the chassis undisturbed by excess shifting and ensures that power will be immediately available (without a downshift) at the corner exit.Cornering G Shift Control is a new transmission feature that debuts on the MDX's Sequential SportShift 6-speed. Cornering G Shift Control monitors the speed of each rear wheel independently to determine when the MDX is turning. When the system detects a sufficient speed differential between the rear wheels, it will suppress an unwanted upshift. This prevents the transmission from upshifting during a corner, which could upset the chassis balance and would then require downshifting again at the corner exit when the throttle is applied.

Temporary Manual Operation in "Drive"
Whether in Drive or Sport mode, "smart" transmission logic programming allows the use of the steering-wheel-mounted paddle shifters. When the driver operates the steering wheel-mounted paddle shifters while in Drive, the transmission responds to the driver's shift command and then returns to its normal fully automatic Drive mode if further paddle shift inputs are not made within a short time. This smart logic makes it easy for the driver to command a quick downshift without leaving the comfort of Drive mode. When in Sport mode, use of the paddle shifters puts the transmission into full manual mode that remains until another mode of operation is selected with the console-mounted shifter.

Manual Mode
By moving the center console-mounted gear selector lever rearward to the detent labeled "S," the transmission is shifted into Sport mode. This mode offers automatic operation with aggressive shift mapping. A pull on the racing-inspired paddle shifters (mounted on the steering wheel) places the transmission in fully manual mode. A digital display in the tachometer face indicates which gear the transmission is in. A new double-kick-down feature lets the driver command a double downshift-such as from Fifth or Fourth gears. By pulling on the left downshift paddle twice in rapid succession, the transmission will drop directly to the chosen lower gear ratio. The Drive-by-Wire™ throttle system also creates a "blip" of the throttle to help match gear speeds while downshifting.

To prevent harm to the powertrain when the transmission is paddle shifted by the driver (including during double-kick-down shifts), the system will inhibit potentially damaging shifts. The Powertrain Control Module (PCM) can also cut off engine fuel flow to prevent over-revving.

If fuel cutoff alone is insufficient to prevent engine over-revving, as may be possible when the vehicle is on a steep downhill, the transmission will automatically upshift to prevent damage. On downshifts, the transmission will not execute a driver command that will over-rev the engine. For improved stop-and-go performance and to prevent "lugging" the engine, the Sequential SportShift transmission will automatically downshift to First gear even though the transmission has been left in a higher gear, (except in Second gear) as the vehicle comes to a stop. When coming to a stop in Second gear, the vehicle will start in Second gear as well.

MULTI-CLUTCH LOCK-UP TORQUE CONVERTER

The all-new 6-speed automatic transmission teams with a brand new torque converter that not only has a higher maximum torque rating, but also has a new converter lock-up assembly. The lock-up assembly uses multiple lock-up disks that generate nearly double the facing area of a typical torque converter. The new lock-up assembly not only reduces heat build-up during operation, but also features improved overall lubrication that generates better cooling. The new torque converter allows for lock-up activation during a much wider range of driving conditions, which, in turn, generates improved fuel economy.

STRAIGHT-GATE SHIFTER ASSEMBLY

The straight-gate shifter is an intuitive and easy-to-use design that takes up little space in the center console. The shifter allows the driver to choose D (using First through Sixth gears) or S, which activates the performance-oriented Sport mode, which has more aggressive shift programming and locks out the use of Sixth gear when operating automatically. When in Sport mode, gear selection via racing-inspired paddle shifters (mounted on the steering wheel) automatically puts the transmission into manual mode, and the driver can select among all six transmission gear ratios.

COOPERATION BETWEEN TRANSMISSION AND DRIVE-BY-WIRE™ THROTTLE SYSTEM

Shift speed and smoothness are enhanced as a result of cooperation between the Drive-by-Wire™ throttle system and the electronically controlled Sequential SportShift 6-speed automatic transmission. During upshifts and downshifts, the engine can be throttled by the engine management system, reducing peak forces (shift shock) on transmission components, thus improving component reliability and decreasing driveline harshness.

SUPER HANDLING ALL-WHEEL DRIVE™ (SH-AWD®)

The MDX features Acura's acclaimed Super Handling All-Wheel Drive™ (SH-AWD®), which progressively distributes optimum torque not only between the front and rear axles but also between the left and right rear wheels. The benefits of the SH-AWD® system are superior all-weather traction and neutral, accurate steering under power that is unmatched by front-drive, rear-drive or conventional all-wheel-drive systems. The 2010 MDX SH-AWD® system is similar to the systems used in the RDX and ZDX SUVs as well as the TL SH-AWD® performance luxury sedan.

By rotating the outside rear wheel faster than the front axle speed while cornering, SH-AWD® torque vectoring creates a yaw moment to help turn the vehicle through the corner-thus reducing understeer and improving handling balance and controllability. With cornering forces more evenly distributed between front and rear tires, overall cornering power is increased- regardless if driving on wet or dry roads.

Vehicles with high power ratings using conventional front or rear drive systems often use a limited-slip differential to help maintain traction when under power. By linking inside and outside drive wheels, these systems tend to resist turning and can increase understeer. Conventional AWD systems similarly work to link the inboard and outboard tires and the front and rear axles, which can create resistance to turning. Using torque vectoring to help turn the vehicle, SH-AWD® creates a more responsive, neutral and predictable platform while retaining the usual benefits of all-wheel drive.

Electronic Controls and Parameters
The SH-AWD® system works in cooperation with the MDX's Vehicle Stability Assist (VSA) system to optimize torque distribution for superior handling and traction. The Powertrain Control Module (PCM) provides information on engine rpm, airflow and transmission gear-ratio selection, while the VSA® ECU provides wheel-speed data. The SH-AWD® ECU also monitors steering angle, lateral G-forces, vehicle yaw rate and electromagnetic clutch engagement for the right and left rear axle shafts. Drive torque is calculated from PCM information, and then the acceleration situation, wheel spin, lateral G forces and steering angle are used to determine the front-to-rear torque distribution and the torque split between right and left rear wheels.

SH-AWD® operating parameters include:

• Up to 90-percent of available torque can be transferred to the front wheels during normal cruising
• In hard cornering and under acceleration, up to 70-percent of available torque can be directed to the rear wheels to enhance vehicle dynamics
• Up to 100-percent of the torque sent to the rear axle can be applied to either rear wheel, depending on conditions

SH-AWD® System Layout
The MDX SH-AWD® is a full-time all-wheel-drive system that requires no driver interaction or monitoring, thanks to a torque-transfer unit that is bolted directly to the front-mounted transaxle. The torque-transfer unit receives torque from a helical gear that is attached to the front differential's ring gear, and a short horizontal shaft and hypoid gear set within the torque-transfer unit's case send power to the rear propeller shaft, which in turn transfers power to the rear drive unit.

The MDX SH-AWD® rear drive unit is constantly overdriven by 1.7-percent and the resulting overdrive effect is regulated by left- and right-side electromagnetic clutch packs within the rear differential that independently control the power delivered to each rear wheel.

Direct Electromagnetic Clutch Systems
Direct electromagnetic clutch systems mounted on either side of the hypoid gear that drives the rear axle control the amount of torque sent to each rear wheel and provide a limited-slip differential function when needed. The clutches can be controlled as a pair to alter front/rear torque split or they can be controlled independently to allow 100-percent of rear axle torque to go to just one rear wheel.

An electromagnetic coil modulates the pressure controlling each clutch pack, which changes the speed of the sun gear within the rear differential's planetary gear set to control the torque sent to each wheel. Electromagnetic control of the clutches permits torque delivery to each rear wheel to be proportioned in an exceptionally quick and precise manner, which reduces wheel-slip in low-traction conditions.

The clutch packs and their friction material are carefully designed to withstand the small amount of continuous slip between front and rear axles created by the 1.7-percent speed differential-all while delivering the durability expected of an Acura product. Through an oil-temperature sensor, the SH-AWD® Control Unit monitors the rear differential's clutch-plate coefficient of friction (that changes with temperature) in each clutch pack and then adjusts the voltage to each electromagnetic coil to compensate. As total vehicle miles accumulate, the SH-AWD® Control Unit uses data from a feedback loop to adjust the voltage supplied to the electromagnetic coils to compensate for any clutch wear, ensuring optimal and consistent transmission of torque.

2010 Acura MDX - Body

OVERVIEW

The 2010 MDX fuses the model's traditional virtues of adaptable space, functionality, safety and environmental responsibility with a more exciting visual presence along with more accomplished handling and ride comfort.

Customers in the luxury SUV arena demand distinctive style. The 2010 MDX ups the game with standard 18-inch aluminum wheels and tires, standard Xenon High Intensity Discharge (HID) headlights and very distinctive front end styling. Driving excitement is equally embraced with a chassis tuned at the Nürburgring circuit and on the autobahns of Germany.

The exterior has bold, clean and advanced styling details with European caché, and it was styled to connect with enthusiast drivers from the moment they first see it. Sitting in the vehicle - and then experiencing it - makes the desire even more intense. Besides featuring a 300 horsepower V-6, the MDX includes Super Handling All-Wheel Drive™ (SH-AWD®), an available Active Damper System along with lightweight aluminum components used in the suspension and body. An additional list of design elements earmarks the MDX as top shelf. These include standard High Intensity Discharge (HID) headlights, plentiful use of high-strength steel, aluminum and magnesium in the vehicle, and convenience features like a standard power rear tailgate. An available Technology Package and Advance Package further enhance functionality and luxury.

EXTERIOR DESIGN GOALS

One of the primary goals in designing the second generation MDX was to keep its previous strengths but advance its performance and image. The clear direction for the MDX was to create a bold and innovative look that clearly conveyed the "Driver's SUV" nature of the vehicle. The new front grille is free of molding breaks for a cleaner look and features dark silver satin plating.

STYLING DEVELOPMENT

The original MDX provided an excellent blend of utility, luxury and style. The 2010 Acura MDX has powerful, dynamic styling that is a continuation of the themes that have been embodied in recent Acura products. Designers found inspiration in a high-powered mega yacht, which features an exceptionally bold, lean and contemporary design. The challenge was to apply the useful elements of the yacht design to an SUV, and designers found their answer in the adoption of large areas of clean surfaces and the addition of decisive line breaks and dynamic surface curvature. Large 18-inch diameter aluminum wheels with performance tires not only benefit handling, but also create a muscular look. In front, the 2010 MDX has a distinctive, advanced Acura look. The platform is long, low and wide to enhance cornering and high-speed stability.

COMPETITIVE COMPARISON

The MDX has a significantly wider track than its primary market competitors. As a result it offers dramatic appearance, packaging and utility advantages.

BODY STRUCTURE

The 2010 MDX utilizes the Advanced Compatibility Engineering™ (ACE™) body structure, which helps distribute collision forces through the entire structure during a frontal collision while helping to retain the integrity of the passenger compartment. The MDX uses a large amount of high-strength steel to help reduce vehicle weight while simultaneously increasing strength. Alternative materials including aluminum and magnesium alloys are also used throughout the vehicle, further reducing vehicle mass, which helps improve fuel economy and increase performance.

Attaining a high level of dynamic body rigidity is essential for precise handling, ride quality and quietness inside the cabin. By researching the body's dynamic response to chassis loads resulting from everyday driving events, MDX engineers considered the unit body's "dynamic stiffness" as an entire system - not just as a single component. Thus, body rigidity is not an end to itself, but rather it is an enabler for enhanced vehicle dynamics, riding comfort and driving quietness.

Instrumented testing revealed that the "tailgate ring" - the open area surrounding the tailgate - is particularly important for handling, stability and ride. In the second generation MDX, this area has been markedly stiffened, providing the rear suspension with a more solid mounting and netting an improvement in handling precision. In addition, the MDX's floor frames are wider than before for improved packaging and rigidity.

HIGH-STRENGTH STEEL

The use of high-strength steel contributes to rigidity, excellent crashworthiness and light weight. High-strength steel is specified in different grades for use in different parts of the vehicle. Some unit body areas using this material include the roof arches, floor cross members, tailgate opening, front rails and body sides.

LIGHTWEIGHT ALUMINUM

About 4.1-percent of the 2010 MDX body components are constructed of aluminum. This material is ideal for certain components such as the hood and instrument panel support, where light weight is preferred and the strength of steel is not imperative.

The hood on the first-generation MDX was steel, and the weight savings of using aluminum instead of steel (for the 2010 MDX hood) is 15.5 pounds. Aside from using a unique metal conditioner and phosphate dip prior to painting, there are no unique production challenges for using an aluminum hood - and no ownership compromises either. To improve environmental efficiency, a factory separation line isolates different scrap materials (including aluminum) for recycling during the manufacturing process.

The aluminum instrument panel support saves an additional 10.5 pounds compared to a traditional steel unit. This support structure, which connects the A-pillars to the front floor crossmember, is a structural element consisting of die cast parts, extrusions and sheet aluminum.

AERODYNAMICS

Acura MDX prototypes spent a total of seven weeks in the wind tunnel to test and develop its aerodynamic properties. The attention to detail in aerodynamic efficiency resulted in the development of body side sills that help keep air from moving underneath the vehicle which can cause turbulence. Coefficient of lift and lift balance were also addressed to help keep the MDX stable at high speeds. In this area, internal testing revealed that the MDX exceeds the aerodynamic performance of the BMW X5.

WIND NOISE

Careful attention was paid to reducing wind noise inside the MDX cabin. An acoustic wind tunnel was used to identify and correct noise issues and an added benefit of wind tunnel testing was the ability to rotate the MDX sideways into the airflow. This allowed engineers to approximate even the most severe gusting side winds and solve unexpected and unwanted wind noise that could accompany such severe conditions.

The MDX's moonroof is larger than used in the first generation MDX and is also the widest of any direct competitor. A finely tuned deflector ensures that the moonroof does not add objectionable wind noise when in the open position, even at highway speeds. Attention to detail in the sealing of the doors and tailgate also heighten the performance of the MDX's overall wind noise level.

INSULATION

Engineers attacked noise from virtually every source inside and outside the MDX. Their primary goal was to reduce noise at its source. One creative noise-reduction technique is the use of composite seals in the exterior door panels. These composite seals actually serve two purposes - to reduce the transmission of noise through the doors and to shield the interior components from dirt and water while driving through rain or puddles. The new door insulators provide a substantial reduction in objectionable sound - up to five decibels on some roads.

DOORS

The MDX's door handles are sized for comfort as well as ease of use, regardless whether the user is bare handed or wearing winter gloves. There are three door checker positions (the detent mechanism that holds the door partially open) instead of the usual two, thus providing a convenient "in between" position useful during tight parking situations. The door openings are finished with an attractive composite garnish that hides the doorsill when the door is open, and for 2010 door striker covers are now used to improve looks.

GLASS

Normally only sports cars use windshields with highly compound curves. Deeply contoured glass is more complex and costly to make, thus it is usually reserved for low-production vehicles. Designers specified deeply curved glass for the MDX for its styling appeal as well as to improve aerodynamic efficiency and quietness. The 2010 MDX uses an acoustic glass front windshield that incorporates a unique PVB film to help quell wind and windshield wiper noise from entering the cabin. The rear glass is also a deep wraparound design - the deepest in the Acura product range.

The MDX has an auto up/down feature for the driver and front passenger's 3.5mm thick side windows. The 2010 MDX offers 273-degrees of outward visibility compared to 266-degrees of visibility for the BMW X5, which is a significant accomplishment considering the increased size of the MDX's head rests mandated by FMVSS 202a (effective September 2009).

All glass from the B-pillar rearward has a gray tint to reduce eyestrain and heat buildup inside the cabin. In addition, the outside rearview mirrors use a special blue glass that provides bright imaging along with excellent glare resistance.

XENON HID HEADLIGHTS

All 2010 Acura MDX models include as standard Xenon high-intensity discharge (HID) low beam front headlights with halogen high beams. The advantages of HID headlamps include greater lighting power, daylight-color light balance and reduced power consumption. In addition, the cut lines of the new HID headlights are extremely precise, providing maximum nighttime visibility without distracting other drivers.

The 2010 MDX features Daytime Running Lights (DRL), which automatically turn on with the activation of the ignition. An MDX fit with the optional Advance Package features an auto-leveling feature that keeps the headlights level regardless of how the vehicle is loaded with passengers and/or cargo.

Halogen fog lamps are also included as standard equipment on all MDX trim levels.

LED TAILLAMPS

Two Light-Emitting Diode (LED) arrays, comprised of 12 LEDs apiece, are used for the taillamps of the 2010 MDX. Similarly, the Center High Mount Stop Lamp (CHMSL) features a single array of 16 LEDs. Advantages of the LED taillights include an elegant contemporary appearance, quicker turn-on time (compared to conventional incandescent bulbs) and significantly greater service life. LED lights are also brighter, smaller, lighter and produce less heat than incandescent lights. The LED CHMSL was selected for its appearance and ability to produce the required lighting brightness while retaining slender physical dimensions. LEDs are also used in the MDX's outside mirror housing-mounted turn signals, improving visibility during lane changes or turns.

POWER TAILGATE

For 2010, Acura's power tailgate system is now standard on all MDX models. The power tailgate can be operated via the remote key fob, from a button located on the driver's door panel, or from a button located inside the tailgate. The location of the motor in the MDX's D-pillar (instead of in the roof) allows excellent headroom for the third-row seats. The tailgate can also be operated manually.

REARVIEW CAMERA

Every Acura MDX uses a camera to display a rear view image. The standard MDX displays the rear view image on a 3.5-inch video screen which is integrated into the auto-dimming rearview mirror, while the MDX with the Technology Package or Advance Package displays an image on the in-dash navigation screen. Furthermore, Technology and Advance Package models offer three different rear view angles -normal rear view, wide angle rear view and a tow-friendly top view. The camera lens is located on the tailgate next to the license plate.

BLIND SPOT INFORMATION SYSTEM

Sensors for the Acura's all-new blind spot information system are located behind the left and right rear bumper fascia. The sensors can detect other vehicles when they are in the blind spot of the MDX driver. The feature uses indicators to alert the driver when another vehicle is detected in close proximity to the MDX.

RESIN FUEL FILLER DOOR

The MDX fuel filler door is operated remotely from inside the vehicle via a switch located on the driver's door panel. The fuel-filler door is made of a composite resin material that is lightweight, dent resistant and corrosion proof. For a better appearance, the inside of the door features a flangeless resin design.

BUMPERS

The front and rear bumpers are constructed of a structural beam covered with a plastic fascia rated to withstand impacts of up to five mph without sustaining significant damage. An attachment point for a tow hook is located under a small cover on each bumper fascia. Removing the cover allows access to a threaded boss that accepts a steel eyebolt located in the jack storage area. New for 2010, the rear bumper fascia now cohesively wraps around and joins with the rear wheel arch trim for a more integrated look. In the front, the new bumper fascia incorporates unique lower side scoops for improved radiator cooling along with stylish looks.

EXTERIOR PAINT

Inspired by the smooth finishes on fine pianos, Acura set out to achieve a mirror-smooth paint finish with a wet, glossy look. To advance the surface smoothness, "orange peel" - the finely undulating surface found on some paints resulting from the evaporation of the paint solvents - had to be all but eliminated. Eight environmentally responsible waterborne exterior colors are available, and each uses a durable clear-coat finish that resists scratching and airborne pollutants.

*Please note: not every interior / exterior color combination is available for every trim. Please consult Acura.com to Build and Price your MDX.

Along with the ZDX and RDX, this represents the first time Acura vehicles are separated from Hondas during the assembly process. It represents Acura's commitment to being at the leading edge of quality and it is befitting of the most exclusive Acura SUV ever created.

2010 MDX EXTERIOR ACCESSORIES

A line of Acura Genuine Accessories was developed simultaneously with the MDX to provide personalization for the Acura owner. Like all Acura Genuine Accessories, the MDX accessories are covered by a 4-year/50,000-mile limited warranty if installed at the time of vehicle purchase.

2010 Acura MDX - Chassis

CHASSIS DEVELOPMENT

From its inception the MDX targeted the dynamics and driving feel of its strongest European competitors. The essential elements of this engineering goal included steering, suspension, braking and overall dynamic performance, as well as excellent noise, vibration and harshness (NVH) control.

In the early stages of MDX development, engineers tested European luxury SUV competitors including the BMW X5, Mercedes-Benz ML, Porsche Cayenne and Volvo XC90. These experiences provided real-world understanding of how these luxury SUVs functioned in everyday driving on their "home turf." Although later development testing was conducted in the United States, the DNA of the MDX was largely formed in Europe.

One essential tool that Acura used was the famed Nürburgring Nördschleife road circuit in Germany. This 13-mile course contains over 170 corners, numerous altitude changes and is considered the toughest natural road course in the world. Engineers used the Nürburgring as a "weakness finder" as it quickly exposes problems with a vehicle's dynamics, making them easier to identify and fix.

In order to build in a combination of increased handling agility, increased stability and comfort, the current MDX's wheelbase, tread width and suspension technology were changed from the first-generation MDX. Engineers changed the lift and squat characteristics of the suspension to provide a flatter takeoff. Thanks to the combination of its wheelbase and SH-AWD®, the 2010 MDX offers both exceptional high-speed stability and responsive handling.

FRONT SUSPENSION

The MDX's entire front chassis was tuned to provide the best balance of handling precision, road isolation and impact aftershake damping. MacPherson struts team with coil-over springs and lower control arms constructed of forged aluminum to reduce unsprung weight. The front subframe "floats" on rubber mounts to provide road and engine isolation, and the subframe assembly is affixed to the main body structure with heavy-duty braces. The front suspension also uses hydro-compliance bushings to provide superior ride isolation as well as excellent chassis vibration control. Suspension and engine mounts are specifically tuned to provide minimum vibration transfer to the occupants, and the front struts employ internal rebound springs to improve ride and handling. Anti-dive properties were specially tuned to reduce impact harshness and improve ride comfort.

REAR SUSPENSION

The MDX's rear suspension is a multi-link design mounted on a separate steel subframe. Squeeze-cast aluminum uprights reduce unsprung weight, while precise trailing-arm mounting points reduce body squat during hard acceleration. Constant rate coil springs, dampers and a stabilizer bar are tuned for the optimum combination of ride and handling. Rear subframe mounts and lateral control link bushing rates create a discrete level of lateral force steer at the rear axle. Since the SH-AWD™ system constantly varies drive torque at the rear axle, the longitudinal and lateral force steer properties were carefully developed for optimum response, stability and consistency.

ACTIVE DAMPER SYSTEM

Many luxury vehicles offer some type of body motion control system using air suspension, electronically controlled dampers or automatically adjustable stabilizer bars. Acura considered all of the available technologies before choosing electronically-controlled "semi active" Magneto-Rheological fluid dampers as the ideal technology to maximize ride comfort and handling- all in one integrated system. Included within the available Advance Package, the Active Damper System gives the 2010 MDX an elevated level of handling precision designed to satisfy the most discriminating drivers, while maintaining a smooth and controlled ride.

The overall goal of the Active Damper System is to achieve an outstanding level of handling response while maintaining a refined level of ride comfort. This allows the driver intuitive vehicle control in a relaxed environment- free from a jarring ride, neck straining head toss and other sudden vehicle motions. This is made possible by the quick response of the dampers as controlled by computer algorithms that keep the dampers a step ahead of actual body movements.

Advantages of the Active Damper System include:

• Flat cornering feel with a reduced body roll- even during spirited driving
• Responsive, precise and secure steering feel
• Elimination of unwanted under-damped body heave, roll and pitch motions
• Improved tire adhesion, vehicle stability and road isolation

Real-Time Damper Control
The secret to the MDX's Active Damper System is its fast-acting "semi active" shock absorbers. These dampers are built and tuned specifically for the MDX and offer the ability to individually adjust from minimum to maximum damping force in as little as five milliseconds (0.005 sec.). Their ability to significantly change damping rate hinges on the principle of electromagnetic induction. Each damper carries a field coil-a collar containing many windings of magnetic wire-that generates an electromagnetic field when current is passed through it. Special damper fluid contains microscopic (about 10 microns in diameter) ferric spheres that align when surrounded by the electromagnetic field, dramatically and instantly changing the effective fluid viscosity. Not only is the overall range of damping force available significantly more than that of a conventional damper, but also there are literally hundreds of small steps available within that range.

An electronic control unit (ECU) determines the amount of electrical current that passes through the field coils via special algorithms which determine the best setting for the road conditions. The continually variable oil viscosity, combined with nearly instantaneous reaction time of the dampers, allows damping control to occur before the MDX's tires or body experience any extraneous motion.

The Active Damper System will deliver low damping when the road is smooth and the vehicle is being driven at a constant speed. Less damping reduces the amount of vibration and harshness that passes from the suspension to the body, quieting and improving the overall vehicle ride quality.

Using the dampers' 5-millisecond response time, the Active Damper System reacts to sudden changes in driver or road inputs. A high damping force achieved in this short time allows the dampers to quickly aid the coil springs and stabilizer bars in roll and pitch control, greatly improving the handling of the MDX.

The result of the improved transient handling, road isolation and body control afforded by the MDX's Active Damper System is a noticeable reduction in the driver's workload. In short, the system is able to achieve the benefits of a sport-tuned suspension without the traditional ride comfort trade-off. The overall benefit is more enjoyment, better control and less fatigue over the long haul.

The computer algorithms that control the Active Damper System were specially created for the 2010 MDX and offer a substantial difference between Comfort and Sport modes. Thus, drivers whose primary interest is comfort will be coddled over most road conditions, while those interested in a sport-driving experience will find the MDX ready to tackle challenging roads.

The Active Damper System does not require any special maintenance, has no scheduled replacement interval and maintains the same quality, durability and performance as all other Acura components.

POWER RACK & PINION STEERING

Of the luxury SUVs that Acura targeted in developing the MDX, the BMW X5 3.0i offered the best steering quality. Acura set out to exceed the BMW's combination of linearity, precise feel and security at high speed by using torque-sensing, power-assist rack-and-pinion steering.

Acura engineers spent considerable energy studying steering "on-center" feel in an effort to elevate the quality of steering feedback the driver receives. Beyond offering the correct steering effort level, the MDX provides subtle transient steering feedback that is an integral part of its subjective handling quality. Notable geometry changes include increasing the rake and trail over the previous MDX to provide a stronger steering feel.

WHEELS AND TIRES

The 2010 Acura MDX has standard 18x8-inch 5-spoke aluminum wheels finished in luxurious silver with a bright-machined face and a chromed Acura center cap. With the standard MDX, fitted to the 18-inch wheels are Bridgestone Dueler H/L 400 P255/55R18 104H M+S all-season tires that were specially developed by Bridgestone for the MDX are fitted to the 18-inch wheels. These tires offer a significant traction improvement in dry and wet conditions, while maintaining the previous MDX's level of snow/ice traction. The MDX with Technology Package uses the same 18x8-inch wheels, but makes use of Michelin Latitude Tour HP P255/55R18 M+S tires.

Available with the Advance Package are new 19x8.5-inch 7-spoke aluminum wheels with Michelin Latitude Tour HP P255/50R19 103H high-performance all-season tires that were specially developed for the MDX by Michelin engineers. The tires offer outstanding traction in dry and wet conditions, while maintaining highly useful level of snow/ice traction as well. Of particular interest, the MDX's tires deliver a 5-percent reduction in rolling resistance- thus helping to improve fuel economy.

4-WHEEL DISC BRAKES

The 4-wheel disc brakes on the 2010 MDX are the largest brake system ever featured on a production Acura vehicle, an honor shared with the all-new 2010 ZDX. The brake system is engineered to provide best-in-class braking capability in dry conditions, as well as while driving in rain, snow or icy conditions.

Engineers benchmarked the Acura MDX against top competitors including the Porsche Cayenne and BMW X5 for braking performance and overall pedal feel. As a result, the MDX has minimal pedal travel and a firm pedal feel, in keeping with the sport-minded direct feel that enthusiast drivers desire. The ventilated front brake rotors measure 13.0-inches in diameter with a thickness of 1.1 inches, while the rear rotors are a 13.2-inch diameter solid design with a thickness of 0.43 inch. The front brake calipers are dual-piston design while single-piston calipers are used in the rear.

The MDX also has an anti-lock braking system (ABS) with Brake Assist, Hill Start Assist and electronic brake distribution as standard equipment, and a Collision Mitigating Braking System™ (CMBS™) is available as part of the Advance Package.

VEHICLE STABILITY ASSIST™ (VSA®) WITH TRACTION CONTROL

Vehicle Stability Assist™ (VSA®) is included as standard equipment on the MDX. By continually monitoring the vehicle's operating parameters (such as road speed, throttle position, steering wheel position, accelerating/braking/cornering loads), VSA® detects if the vehicle is experiencing oversteer or understeer. To help correct either of these situations, VSA® automatically cuts the throttle to reduce engine power output as needed, and applies one or more brakes individually to help stabilize the chassis. The VSA® response is so quick that the instability may be corrected even before the driver knows it's occurring. Traction Control is integrated into VSA® and helps the MDX accelerate smoothly on low traction surfaces. As stated in the SH-AWD™ section, VSA® works with SH-AWD™ to adjust engine torque distribution- thus allowing Direct Yaw Control of the MDX to maximize stability under all driving conditions.

TIRE PRESSURE MONITORING SYSTEM (TPMS)

An onboard Tire Pressure Monitoring System (TPMS) warns the driver if the air pressure decreases significantly in any tire. The system helps reduce the chance of damaging a tire or losing control of the vehicle due to low air pressure. This is important because a slow leak, such as one that might be caused by a nail or road debris, might not be easily detectable-but over time could cause significant air loss, reduction of grip and potentially a blowout.

TPMS uses a sensor mounted on each wheel that continually monitors tire pressure and sends a coded signal to the TPMS electronic control unit (ECU). The process begins with a signal initiator located inboard of each tire on the chassis that sends a unique signal for each TPMS sensor. The TPMS sensor then sends tire pressure data to the TPMS ECU, which compares the values for each tire's pressure against an acceptable range of pressures.

When a tire's pressure drops significantly below the proper level, a "CHECK TIRE PRESSURE" alert will appear on the Multi-Information Display (MID) screen. The TPMS system can display the air pressure in all four tires simultaneously via the MID, making it simple to locate a specific low-pressure tire. If there is a fault in the system, a "CHECK TPMS SYSTEM" alert appears.

At the driver's preference, the Multi-Information Display can continually show the air pressure in all four tires. Regardless of whether the driver chooses to monitor the pressures, a warning will still occur if a tire drops a specified level.

OFF-ROAD CAPABILITY

Acura took thorough measures to ensure that off-road enthusiasts would be satisfied with the MDX. The 2010 MDX meets design criteria developed for the original MDX, which was based on research at different off-road areas across the country. This research was the foundation for specific minimum performance criteria for the new MDX, including travel through standing water nearly 19-inches deep, approach and departure angles (22.2-degrees front and 23.8-degrees rear), off road and paved grades up to 60-percent. Components located underneath the vehicle are tucked away to avoid damage in off-highway driving and the evaporative canister is protected by a high-strength steel guard.

The high-torque 3.7L V-6 engine, SH-AWD® system with hill logic and computer-controlled traction control capabilities help the MDX meet typical off-road challenges without the need for low-range gears. The MDX outperforms its predecessor without the need for a driver-selected 4WD "lock" mode.

SNOW AND ICE CAPABILITY

The same technologies that make the MDX capable off-road also enhance its performance in snow and ice. The SH-AWD® system with grade logic and computer-controlled traction control capabilities work together with the standard M+S tires to maximize power delivered to the road surface, and thus driver control, during winter driving conditions.

NOISE, VIBRATION & HARSHNESS (NVH)

The MDX uses an array of technologies to reduce noise, vibration and harshness (NVH) in the passenger cabin. Acura began by attacking vibration in the body during the engineering phase instead of simply adding materials to the body to damp it out later. Two examples of this process are new rear suspension mounting points, which are now attached to the unit body for greater rigidity and reduced vibration, and the stiffening of the front and rear subframes, which allowed the mounting bushings to be made softer.

Engineers paid strict attention to addressing two specific issues - concrete road noise and drumming - neither of which is acceptable to luxury customers. By nature SUVs are susceptible to drumming noises in the cabin interior because of their large open area. Where necessary, meltsheets are used in critical areas on the front bulkhead and floor, and lighter insulators are used on the bodysides, doors and roof. A new hybrid carpet and padding system further reduces noise intrusion by balancing the transmission loss and absorption properties of the carpet.

To verify that the results were on target, engineers dynamically shook the MDX body and measured vibration by scanning the floor with lasers to find any "hot spots". This scanning process provided exact information on where to focus efforts. As a result, the MDX is 20-percent stiffer and quieter than the previous version, registering just 64 dBA at 60 mph.

TOWING

With a towing capacity of 5,000 pounds the MDX can pull a boat or camper trailer with confidence. Standard towing equipment includes a high-capacity radiator with twin 160-watt electric fans, an automatic transmission fluid cooler, a heavy-duty power-steering cooler and pre-wiring for an electric brake controller. A Towing Package is available as dealer-installed accessory and includes a Class III hitch, receiver, ball and wiring harness.

One of Acura's durability tests was towing a 5,000-pound trailer in Death Valley National Park during summer, including repeated climbs up Townes Pass and Daylight Pass with outside air temperatures between 113- and 120-degrees F. Testers also targeted the toughest boat ramp they could find - at Shasta Lake in Northern California - where the launch ramp is extremely steep, and its length varies depending on the lake level. They also proved the MDX trailer-pulling skills elsewhere in California as well as in Kentucky and West Virginia.

TRAILER STABILITY ASSIST

Every 2010 MDX comes with standard Vehicle Stability Assist™ (VSA®) that includes special Trailer Stability Assist algorithms. Trailer Stability Assist interprets oscillation (or wag) in the vehicle/trailer combination while driving. This may occur if the trailer is not loaded correctly, or during certain speed and road conditions. Using a combination of torque reduction and individual brake application, Trailer Stability Assist activates to stabilize the vehicle after sensing oscillations of the vehicle and trailer system.

MANUFACTURING

The 2010 Acura MDX is assembled at Honda of Canada Manufacturing in Alliston, Ontario. A special dynamic quality-control process is employed to ensure the highest possible level of attention to detail for every MDX produced. After assembly is completed, each MDX enters a special Acura Quality line. The ability to immediately respond to the smallest quality issue allows the MDX to excel in quality - and in customer satisfaction.

ENVIRONMENT

For years, Acura vehicles have been successfully meeting ever more stringent world guidelines to reduce the content of harmful metals such as chromium and lead, along with reducing volatile organic compounds (VOC) and polyvinyl chlorides (PVC). To reduce environmental impact at the factory, a special separation line isolates different manufacturing scrap materials, including aluminum, for recycling. The 2010 MDX marks the first Acura to use a mercury-free Navigation display screen, which features LED backlighting instead of traditional cold cathode backlighting.

2010 Acura MDX - Interior

OVERVIEW

The core themes of driving enthusiasm, intelligent functionality, top technology and luxury are clearly evidenced in the MDX interior. Acura's flagship SUV blends sport sedan intensity with the best elements of SUV utility. In keeping with Acura tradition, the MDX integrates the latest technology into a seamlessly intuitive package that puts the emphasis on driving.

For 2010, new attention to detail and luxury further distinguish the MDX interior. Expanded use of Milano leather, more comfortably located front seats headrests, thicker steering wheel grip, more detailed hand stitching (such as the Lancia-style stitching on the steering wheel and shift knob), new speedometer assembly and updated cockpit controls make it clear that the MDX is focused on the driver - but not at the expense of passenger comfort. The power driver seat adjusts 10 ways (8-way power seat with 2-way power lumbar support) for optimum comfort, and the front passenger seat is 8-way power adjustable. The second-row seats mirror the style and lateral support of the front seats, giving the MDX interior a unique 4+3 feel that highlights its blend of sport and utility. Convenience and cargo features abound, including under-floor storage in the rear cargo compartment and a standard power-operated rear tailgate.

As Acura's flagship SUV, the MDX offers a formidable list of standard equipment. A leather-wrapped multi-function steering wheel provides the driver with fingertip control of key functions in an interior environment that's maintained by a tri-zone climate control system with humidity control. New backlit LED instrumentation and Acura's legendary attention to function and feel make the MDX driver seat the place to be.

Standard with MDX is an 8-speaker Acura Premium Sound System audio system with 6-disc CD changer, AM/FM radio, XM® Radio and Bluetooth® Audio. Also standard is an auxiliary jack interface (for portable MP3 music players). The standard Bluetooth® HandsFreeLink® wireless telephone interface makes it easy to send and receive telephone calls on a compatible cellular phone without the driver needing to take his or her hands off the wheel or look away from the road. For 2010, a new auto-dimming rearview mirror includes an integrated rearview camera display.

The Technology Package adds a range of advanced features designed to offer drivers increased connectivity to the world around them along with added driving enjoyment. Inside, luxurious full-grain Milano premium leather covers the seating surfaces. The Acura Navigation System with Voice Recognition™ system uses a new 8-inch full VGA, LED-backlit, high-resolution color display positioned high up in the center of the instrument panel where it is close to the driver's line of sight while remaining shrouded from glare. With navigation data stored on a built-in hard disk drive (HDD) media storage device, the navigation system now boots up and operates with impressive speed.

The navigation system includes AcuraLink Real-Time Traffic with Traffic Rerouting™ along with the AcuraLink Real-Time Weather™ including weather radar image maps. For the ultimate in connectivity, AcuraLink® Satellite Communication System allows direct communication between the MDX and Acura, including the ability to make automated appointments for vehicle service.

Acura's renowned Acura/ELS Surround® premium audio system is part of the Technology Package, featuring a 410-watt Digital Sound Processor amplifier, a 10-speaker surround sound array, along with a built-in 15-gigabyte hard disk drive (HDD) media storage system that allows the MDX owner to download and store about 3,500 songs* for later playback.

CONCEPT AND STYLING

The interior styling of the MDX is based on three key concepts: a driver's oriented cockpit, 4+3 seating and a dynamic and layered overall interior look.

Driver-Oriented Cockpit
To put the MDX's various systems under the clear control of the driver, a "Driver-Oriented Cockpit" theme guided the design of the cockpit. Analog central instrumentation is supplemented with digital and graphic displays. The interface with the MDX's many advanced systems is simple and intuitive. Sight lines are clear with important items placed within easy view. The MDX's console-mounted straight gate shifter is intuitive to operate and racing-inspired paddle shifters on the steering wheel provide easy fingertip control of the new 6-speed automatic transmission.

Frequently used systems, such as the audio system and cruise control, have switches conveniently positioned on the steering wheel. The multifunction Interface Dial, which operates navigation system functions, is positioned just ahead of the shifter lever within easy reach.

4+3 Seating
The concept of 4+3 seating emphasizes the comfort, luxury and style of the front seats and the outboard second-row positions. These seats share the same styling theme, and have substantial side bolsters to provide secure lateral support when the MDX is cornering. The second-row center position and the two seating positions in the third row are used less frequently and, as such, styled more stealthily. Nested headrests in these positions provide a clean appearance and, in the third row, allow the seat to be folded flat without the need to remove the headrests.

Dynamic Styling
The MDX envelops its passengers with dramatic shapes that sweep from the center console, across the instrument panel and then into the door panels. Sculptural and warm wood-patterned trim creates a zone of luxury for the front passenger. Rich textures interplay with sleek metallic accents in the MDX interior to create an atmosphere of luxury and advanced technology.

INTERIOR MATERIALS AND CRAFTSMANSHIP

The MDX pushes interior luxury to a new level with a range of thoughtful touches. Special care has been taken to create surfaces with a pleasing tactile feel. Door grab handles have a soft-touch grip, the instrument panel has a soft feel and a seamless passenger airbag cover, and passenger grab handles have a dampened motion. Quality is further revealed in the soft, low-gloss instrument panel top, detailed door panels, door sash garnishes and flush seatbelt upper anchors.

SEATING

In keeping with its 4+3 seating arrangement, the MDX offers two types of seating. To provide a blend of sporting support and comfort for four passengers, the MDX has deeply-bolstered sport sedan seating in front and in the outboard second-row positions.

The front bucket seats and outboard rear seats have pronounced side bolsters to provide lateral support for aggressive cornering, along with abundant comfort for long drives. For 2010, the front seat headrests have be repositioned 19mm rearward to offer more comfort for occupants. On the Advance Package, the front seats feature a specific type of seat base foam that improves damping of small vibrations for improved comfort. Redesigned seat frames and power adjustment mechanisms reduce flex for a more solid feel. The driver seat is 10-way power adjustable (8-way power seat with 2-way power lumbar support) and is part of a 2-driver automatic memory system that includes settings for the exterior mirrors, climate control and electronic presets. The front passenger seat is 8-way power adjustable. Both front seats are heated and, with the MDX's Entertainment Package, the second row outboard seats are heated as well.

For easy access to the third row of seats, the passenger-side second-row seat slides forward and the seatbacks flip forward.

SEATING SURFACES

For 2010, the Technology Package now features use of Milano premium leather seating surfaces for the first and second row seats that utilize a soft and flexible tanning system, solid embossing and color coating. The result is a softer, richer feel coupled with excellent durability. In addition, contrasting color French seams on the center armrest, door armrest, and seats are part of the Advance Package trims.

For an even sportier look and feel, the Advance Package features breathable, perforated Milano premium leather in the front seats, which also assist the ventilated seat function. In addition, contrasting color French seams on the center armrest, door armrest, and seats are part of the Advance Package trims.

The Milano premium leather included in the Technology and Advance Package is the softest leather ever offered in an Acura. This full grain leather has not been corrected or altered and shows the natural leather grain. A soft, flexible coating system provides maximum softness while retaining excellent abrasion resistance.

LEATHER-WRAPPED STEERING WHEEL

The MDX's power-adjustable tilt/telescope steering wheel is wrapped in premium smooth-grain leather with Lancia-style stitching. Within fingertip reach are a pair of LED illuminated, racing-inspired paddle shifters that upshift and downshift the Sequential SportShift 6-speed automatic transmission.

The steering wheel incorporates the most commonly used controls, allowing the driver to keep hands on the wheel a larger percentage of time. Audio system controls are positioned on the left spoke, along with a push-to-talk button to activate the voice recognition system that provides voice control of navigation, climate control and audio system features. Also on the left are controls for Bluetooth® HandsFreeLink® system. Located on the right spoke are controls for the MID and cruise control.

The Advance Package includes a steering wheel with larger shift paddles with grippy elastomer rubber backs and silver coloring. In addition, the steering wheel has an added Adaptive Cruise Control button on the lower right side and revised MID control buttons.

STRAIGHT-GATE SHIFTER ASSEMBLY

The 2010 MDX employs a straight-gate transmission shifter assembly (located in the center console) that has an intuitive, easy-to-use design. The shifter allows the driver to choose D (Drive), or S (Sport), the latter of which activates more aggressive transmission shift programming.

INTERIOR CONVENIENCE AND UTILITY

Thoughtful features abound in the MDX interior. The front center console has individual armrests for driver and passenger to allow for storage access without disturbing the other armrest. In the second row, the flip-down padded center console features pullout dual cup holders. All four doors offer storage pockets, and storage for sunglasses is provided in the front overhead console. Storage pockets and cupholders add convenience to the third row seating area. Under-floor storage, grocery bag hooks and cargo tie-down points boost cargo area usefulness.

The MDX interior offers an array of storage and convenience features for the driver and passengers. The front center console is internally illuminated, includes a 12-volt power point and a USB port (as part of the Technology Package) that allows for easy connectivity of an iPod®, iPhone® or a removable mass storage device. The USB port is located alongside an analog AUX jack (that allows connectivity of MP3 music players) in the center console.

CARGO CARRYING VERSATILITY

The MDX easily adapts to a variety of missions. In all, there are six possible configurations for the MDX's three rows of seating. Behind the rear seats, there are 15 cubic feet of storage that's easily accessible though a power operated rear hatch. With the 50/50 third row seats folded flat (the headrests can be left in place), the cargo capacity jumps to 42.9 cubic feet. For the maximum cargo volume of 83.5 cubic feet, the 60/40 split flat-folding second row seats can also be folded down, producing a flat load floor in the rear.

POWER TAILGATE

Acura's power tailgate system is now included as standard on MDX models. The power tailgate can be operated via the remote key fob, from a button on the driver's door panel, or from a button located inside the tailgate. The location of the lift motor in the MDX's D-pillar (instead of in the roof) allows excellent headroom for the third-row seats. The tailgate can also be operated manually.

INTERIOR LIGHTING

Significant engineering went into the MDX's interior lighting to provide clear visibility, the right ambience and optimized illumination levels regardless of outside lighting. The analog instruments are LED backlit, with high-contrast markings and a subdued blue accent hue. Transparent illuminated pointers provide clarity and a high-end look. Auto Interior Dimming automatically and progressively adjusts the instrument and navigation system (if so equipped) illumination to suit the outside lighting conditions. The sensitivity is owner-adjustable to one of five different levels, or interior dimming may be switched off entirely.

The MDX has a progressive self-illuminating gauge package. When the door is first opened, the instrument lighting comes to life, and then brightens progressively when the ignition is switched on. The illuminated instrument needles and enunciator lights then come alive, indicating that the MDX is ready to drive. When the ignition key is switched off, the instrument lighting dims progressively.

For easy location in the dark, all of the MDX's switches are illuminated, including those on all four doors and the steering wheel. Low-level blue LED ambient lighting in the ceiling and floors (for driver and front passenger) illuminates the front center console and LED map lights are provided for all three rows of seats. A dome light is provided above the third-row seats. All four doors have courtesy lights that are illuminated when the doors are open and the rear tailgate has two lights that illuminate the area immediately behind the vehicle for easier cargo loading. The MDX interior lights feature "theater dimming," which can be set via the MID by the driver to any of three dimming times.

TRI-ZONE AUTOMATIC CLIMATE CONTROL SYSTEM

To maximize passenger comfort, the MDX has standard tri-zone automatic climate control that allows the driver, front passenger and rear zone to be set to different temperatures. Rear zone controls are conveniently positioned on the rear of the center console. With the touch of a button, the driver can synchronize the rear temperature with that of the driver area at any time.

When equipped with the Technology Package, the climate control benefits from GPS-linked, solar-sensing actuation. Based on its continuously updated vehicle position information, the navigation system determines the position of the sun relative to the driver and passenger. When in AUTO mode, this information is combined with input from the solar sensor located on top of the instrument panel to automatically adjust the temperature from side to side as needed to compensate for asymmetrical solar heating.

Humidity Control System
To help avoid window fogging, the MDX's automatic climate control system has a cabin humidity control system. This new control system provides greater passenger comfort and minimizes the time the air conditioning runs. When set to operate in AUTO mode, a temperature and humidity sensor located in the front of the passenger cabin monitors the interior climate. If the system determines that there is a low probability of window fogging, it maintains a comfortable humidity level of around 20-percent.

If the system determines that potential window fogging conditions exist, it changes the climate control parameters to help keep the windows clear. In these situations, the air conditioning system is set to MAX, the air outlet mode is switched to HEAT/DEF and the fan speed is gradually increased to reduce the chances of window fogging.

MULTI-INFORMATION DISPLAY AND MAINTENANCE MINDER™

Positioned between the tachometer and speedometer, a Multi-Information Display (MID) gives the MDX driver instant access to important information. Controls positioned on the steering wheel allow the driver to cycle the MID display through multiple screens of information. With a large screen area, high resolution and the ability to display varying font sizes, the MID is clear and easy to interpret.

There are two individual trip computers built into the MID system, with easy tracking of overall mileage, individual trip mileage, average fuel economy, average speed, fuel range and elapsed time. The MID also displays outside air temperature as well as remaining percentage of engine oil life. The Maintenance Minder™ system alerts the MDX driver of upcoming maintenance needs via the MID and should a fault occur with the vehicle, specific warning information will appear. The MID also allows the driver to set a variety of preferences for different MDX systems.

REARVIEW CAMERA

When the MDX is placed in Reverse gear, the view from a rear-mounted camera is displayed on a video screen built into a new auto-dimming rearview mirror. To make it easier for the driver to judge distance and clearance, solid yellow on-screen guidelines indicate the vehicle's width, as well as distances of 1, 2 and 3 meters as measured from the rear of the MDX. In addition, a dotted yellow line marks off the distance required to open the rear hatch. When equipped with the available Navigation system (as part of the Technology Package), a multi-view camera is standard and projects one of three different rear views on the 8-inch full VGA high-resolution color display. The primary view is "Normal View," which delivers 130-degrees of rearward visibility. For special conditions, there is the "Wide View," which delivers 175-degrees of rearward visibility. Finally, the "Top Down View" generates a straight-down look at the trailer hitch area or parking area- thus greatly easing alignment of the trailer and the MDX's available Class III towing hitch or helping when maneuvering in tight parking spaces.

OVERHEAD CONSOLE

The overhead console incorporates a variety of useful features. Controls for the standard HomeLink® system are positioned here within easy reach. This latest generation of HomeLink® is simpler to program. Other overhead console features include sunglasses storage, controls for interior lighting and the power tilt/slide moonroof.

253-WATT ACURA PREMIUM SOUND SYSTEM

To give owners excellent sound quality along with the ability to enjoy a wide range of audio formats, the MDX comes standard with a 253-watt Acura Premium Sound System with AM/FM tuner, XM® Radio, in-dash 6-disc CD/MP3/WMA changer and 8 speakers, including an 8-inch subwoofer.

Prominently positioned just below the center instrument panel vents, the MDX audio system has large-format controls that make the system easy to operate. The audio system sends a total of 253 watts of power through six channels and eight speakers. The instrument panel has a 1.5-inch soft-dome tweeter positioned on each side, with a 3-inch mid-range polypropylene cone speaker centered atop the dashboard. Mid/low-range 6.5-inch dual thickness polypropylene-cone speakers are positioned in each door, and an 8-inch subwoofer is located in a special tuned enclosure in the sidewall of the rear cargo compartment.

The audio system can play CD, CD-R/RW, CD-Text and MP3/WMA discs, in addition to AM/FM radio. Embedded text information on CDs can also be displayed. To make a high-quality audio connection simple for owners who have personal music players, the MDX has an easily accessible auxiliary input jack with a nearby 12-volt power outlet.

The AUX connection requires the music player to be controlled via the device's own interface (though the MDX's audio system can control volume). Speed-dependent volume control automatically adjusts as road speed increases to maintain a clear and comfortable sound level. The amount of compensation can be set to three different levels or turned off completely.

The MDX audio system includes XM® Radio, which provides more than 170 channels of digital program material and near-CD quality sound. Informational text on the programming appears on the audio system display. XM® Radio offers virtually uninterrupted coast-to-coast coverage of the 48 contiguous states and coverage to densely populated regions of Canada; service for Alaska and Hawaii is not available at this time. Three months of complimentary XM® service is provided with the MDX. When equipped with the Technology Package or Advance Package, the complimentary period also includes AcuraLink Real-Time Traffic™ service. After the complimentary period, XM® Radio requires a monthly subscription.

XM® programming includes channels devoted to music, sports, talk, traffic, weather, children's programming and entertainment. Of the more than 170 XM® channels, 69 are commercial-free. When the MDX's audio system plays XM®, the display screen shows the current station, song title, or artist's name.

The MDX's audio system can also play Bluetooth® Audio when paired with a compatible device. Bluetooth® Audio is a wireless music transfer format that is separate from Bluetooth® HandsFreeLink®, which is used for telephone voice communication.

ACURA/ELS SURROUND® PREMIUM AUDIO SYSTEM

The MDX with Technology Package or Advance Package is equipped with a spectacular Acura/ELS Surround® premium audio system with 10 speakers and an impressive 410 watts of power. This highly capable audio system is the latest generation of the acclaimed Acura/ELS® system offered in other Acura products. In addition to providing exceptional audio performance, the Acura/ELS® audio system is designed to be simple to operate. Clear, large-format head-unit controls and convenient steering-wheel-mounted controls make operation intuitive. Select audio system functions can also be accomplished via voice commands.

For the first time in an Acura, the audio system offers Song By Voice™ (SBV), which allows the driver to make music selections for music on a iPod® or on the HDD by simply speaking the artist name, song name or other selection categories. In addition, a new phonetic modification feature allows the MDX owner to specially program phonetically challenging song artist name(s) to be more easily recognized.

The MDX audio system plays DVD-Audio discs, an advance in reproduction technology that delivers over 500-times higher resolution than traditional CD audio. DVD-Audio delivers smoother, fuller and far more accurate sound through six discrete channels. The DVD-Audio system will not play DVD-V or DVD movies. The system also includes Dolby ProLogic II to create a surrounding experience from a variety of music sources.

The Acura/ELS® audio system gets its name from multi-time Grammy® Award winning producer/engineer Elliot Scheiner's recording industry-recognized moniker "ELS®." Scheiner's goal in the development of the MDX audio system was to capture and reproduce music the way it is heard in a professional recording studio. The sophisticated ELS® system Scheiner developed together with Panasonic is designed to provide studio quality sound within the 2010 MDX.

The Acura/ELS Surround® premium audio system can play material from a wide variety of sources:

• Single disc player:
  • DVD-Audio
  • CD audio
  • DTS CD
  • MP3 or WMA files (on CD or DVD)
• 3,500-song*, 15-gigabyte hard disk drive (HDD) media storage system (including audio track information provided by Gracenote®)
• AM/FM radio with Radio Data System (RDS)
• XM® Radio with Note function music reminder
• Bluetooth® Audio
• USB port connectivity for items such as an iPod®, iPhone® or removable USB mass storage device
• Auxiliary jack connectivity for a portable MP3 player

*Approximate capacity based on an average size of 4.2 MB per song at a 128kbps bitrate

The Acura/ELS® audio system's wide range of formats enables it to play audio program material from most common sources. The addition of a hard disk drive (HDD) media storage system means that the MDX owner can download CDs directly to a dedicated 15-GB hard drive for later playback. Only original CDs and uncompressed CD-R files can be copied to the hard drive. Other formats such as DVD-Audio, MP3/WMA, DTS CD, USB, Bluetooth® audio and AUX inputs can not be recorded to the hard drive.

The audio system's AM/FM radio tuner includes the Radio Data System (RDS). RDS allows digital information sent in many FM radio broadcasts to display on the vehicle stereo items such as program information, artist/song name and time. XM® Radio with Note feature is integrated into the receiver to provide more than 170 channels of digital program material with near-CD quality sound. A text display provides information text on the XM® program material.

Speakers/amplification
The Acura/ELS Surround® premium audio system's 10 speakers create an accurate and dynamic listening experience for all MDX seating positions. Compact 1.5-inch soft-dome tweeters are positioned in each A-pillar with a 3-inch Super Dynamic Range (SDR) driver centered in the top of the instrument panel. A 6.5-inch SDR driver is positioned low in each door panel. Two forward-firing 3-inch speakers are positioned in the rear roof pillars-one on each side. An 8-inch diameter subwoofer driven by a dedicated 100-watt amplifier is placed under the rear cargo floor in a special 9-liter acoustic enclosure. The subwoofer provides powerful bass response and very low distortion over an extended frequency range. A 410-watt Digital Signal Processing (DSP) amplifier drives the speaker array.

Hard Disc Drive
The MDX has a 60-gigabyte hard disc drive (HDD) storage system with 15-gigabytes of media storage- partitioned to hold about 3,500 songs*. (The balance of the HDD's capacity is used for the navigation system.) The hard drive's fast file-access time speeds search and retrieval of audio tracks, and allows tracks to be shuffled by album, artist and genre. On-board information provided by Gracenote® (formerly CDDB®) allows the system to display the song artist, album name, track name, and genre for the program material that is stored on the HDD. Gracenote® uses a multi-step recognition method to enable identification, categorization and organization of digital music. The Gracenote® database is updated quarterly to include new audio releases. The MDX owner can download Gracenote® updates at www.acura.com and then load the updates onto a USB thumb drive or CD-R which, in turn, can be downloaded into the MDX's audio system. Even without a Gracenote® update, newly released audio tracks will play on the Acura/ELS® system, but will play without accompanying text information on genre, artist, album name and track name.

*Approximate capacity based on an average size of 4.2 MB per song at a 128kbps bitrate

Connectivity
For 2010, the Acura/ELS Surround® premium audio system now offers USB port connectivity for external items such as iPod®, iPhone® or removable USB mass storage devices. Located within the center console, the USB port connectivity can charge a device while simultaneously transferring information to the audio system. USB-connected devices can be operated via the audio controls, with filenames and folders appearing on the audio system's text display. In addition, an AUX input jack (with a nearby 12-volt power source) allows for the connection of an external audio source such as an MP3 player.

Moreover, the Acura/ELS® audio system can play Bluetooth® audio when paired with a compatible device. (Bluetooth® audio is a music format that is separate from Bluetooth® used for telephone voice communication.) These devices can be operated and navigated via the audio system's controls.

Note Function for XM®
The MDX's audio system includes the Note function for XM® Radio which is designed to be a convenience for owners who want to make note of songs heard on XM®. With the touch of a button, the Note function for XM® Radio records the current song title and artist name in text form, along with a short audio excerpt of the song.

The Note function captures up to 10 seconds of each selected song and can store a total of 30 song excerpts for later playback. Thus, if the MDX driver likes a particular song or artist, it's easy to note and refer back to for later consideration.

Song By Voice™
With so much audio content potentially available in the MDX's hard drive and in a user's iPod®, Acura engineers set out to make it easy to choose content while driving. Song By Voice™ (SBV) lets the driver choose music by artist, album, track name, genre, playlist and even composer. From most navigation screens, the driver simply presses the "TALK" button on the steering wheels and then says "iPod Search" or "HDD Search." A category screen appears, and the user can choose among categories by voice to select the content they want. Alternately, selections can also be made using the interface dial. To improve voice recognition performance with unique words, the system has a feature that accommodates phonetic adjustment for up to 2,000 names. These updated phonetic names then apply to Song By Voice™ use of the hard drive or a connected iPod®.

BLUETOOTH® HANDSFREELINK® WIRELESS TELEPHONE INTERFACE

All Acura vehicles have a standard Bluetooth® HandsFreeLink® telephone interface that is designed to work with a wide variety of Bluetooth® enabled mobile telephones. Bluetooth® is a radio frequency-based technology which allows portable devices (such as cellular telephones, PDAs, laptops and other devices) to communicate wirelessly over a limited distance. The MDX's HandsFreeLink® system is compatible with Bluetooth®-enabled cellular phones that have the Hands Free Profile (HFP). (Some early Bluetooth®-enabled phones do not have this communications protocol, but most newly released phones have HFP.) After the driver completes a one-time pairing process, the MDX can communicate wirelessly with the driver's cell phone when it is within approximately 10 feet of the vehicle. The telephone needs to be on (with Bluetooth connectivity enabled), but can be stowed in a pocket, briefcase, purse, or anywhere inside the MDX cabin.

With Bluetooth® HandsFreeLink® the driver can answer or make telephone calls without removing their hands from the steering wheel. When a call comes in, the incoming caller's telephone number is displayed on the Multi-Information Display (MID). In addition, a phone ring tone can be played over the audio system. If the driver chooses to answer the phone call, a press of the steering wheel-mounted "Pick up" button mutes the audio system and the incoming caller is heard over the MDX's audio system speakers. On Technology Package models, a special overhead array microphone cancels "echo effect" and reduces background noise to improve the transmission quality of the driver's speech when using the HandsFreeLink® system.

By activating the Bluetooth® HandsFreeLink® system using fingertip controls mounted on the steering wheel, the driver can dial a telephone number by voice. The driver also can store frequently called numbers in the system's memory using unique voice tags. Up to six different compatible mobile phones, each with a unique "user profile", can be paired with the MDX's Bluetooth® HandsFreeLink® system at one time. Each phone profile has its own password-protected call history, phonebook, speed dials and voice tags. With a single paired phone and the proper password for each profile, a user can access any of the other profiles. This convenient feature means that a person who carries both a work cellular phone and personal phone can easily access both profiles from either phone.When equipped with the available navigation system (Technology Package or Advance Package), some HandsFreeLink® functions are displayed on the high-resolution navigation system screen. This provides a versatile interface for HandsFreeLink® operation. The system can also import a compatible cellular telephone's phonebook (over 1,000 entries), allowing the data to be more easily searched via the 8-inch full VGA high-resolution navigation screen.

System Operation
The Acura Navigation System with Voice Recognition™ tracks the MDX's position based on positioning data from up to 12 orbiting Global Positioning Satellites (GPS). If GPS reception is blocked by a tall building, tunnel, or parking garage, an internal gyroscopic system with a speed sensor tracks the location to keep the mapping information current and reliable until satellite reception is restored.

The MDX's navigation system stores its mapping data on an internal hard disk drive (HDD) media storage system. The same drive is also partitioned and used by the audio system to store audio files. Much faster than the DVD drive used on many other systems, the MDX's new hard drive is the key to the system's impressive search and routing speed. The system can be updated annually with the latest mapping information by inserting an update disc into the audio system's slot-loading CD/DVD drive. DVD update discs are available for purchase on an annual basis on-line at www.acura.com, by calling 888-549-3798.

The navigation system can be controlled by using the interface dial by choosing menu options or by spelling out a word (e.g., an address, business name or place). Characters on an on-screen keypad can be selected using the Interface Dial. For voice operation, the driver simply presses the "Talk" button on the steering wheel and says any of a number of preset command phrases. The system responds to over 700 command phrases, as well as to spoken city and street names. Voice recognition capability saves time and simplifies operation of the system.

The audio system is automatically muted when the "Talk" button is pressed, and an overhead array microphone receives the command from the driver. Commands can be given in plain English, like "Display gas stations," "Find nearest hospital," or "Find nearest Chinese restaurant." The 2010 MDX's voice recognition technology allows the owner to simply speak city and street names aloud, and the system responds by displaying matches available in the database. Points of interest on the map (such as restaurants or grocery stores) can be displayed or you can have the system provide turn-by-turn navigation - all by voice command. The massive point-of-interest (POI) database includes telephone numbers, which can be dialed by using the Bluetooth® HandsFreeLink® system or with the driver's cellular telephone.

Wallpaper image display
To further customize the MDX's interior, the navigation system allows the storage of up to 10 images each for each driver (two drivers total) on the built-in hard disk drive (HDD) media storage system. Any one of the stored images can be displayed as a full-screen image on the navigation display when the display is not otherwise in use. To avoid driver distraction, there is no "slide show" function. J-peg images can be loaded from a computer onto a USB storage device, such as a thumb drive. Then the thumb drive can be plugged into the MDX's USB port that is located in the center console. Using on-screen menus, the images can then be transferred to the MDX's internal HDD. Each driver can then choose among their stored images for display, or set the system to not display wallpaper.

ACURALINK® SATELLITE COMMUNICATION SYSTEM

The Technology Package or Advance Packages include the AcuraLink® Satellite Communication System (within the 48 contiguous United States). AcuraLink® allows two-way communication between Acura and the MDX, providing customers with the latest information specific to their vehicle. Once the owner has enabled its data-transmission function, the owner's Bluetooth® telephone is used in cases where communication from the car to the Acura Telematics server is needed. In addition, while driving, the AcuraLink® system conveniently allows the MDX owner to make automated appointments for vehicle service. The data connection from the server to the vehicle is enabled even if the monthly XM® service package is not in effect.

Each AcuraLink® message is prioritized by importance; high priority messages are displayed immediately while normal messages trigger a message icon on the navigation display. To avoid distraction, some low priority messages show up only on vehicle start-up. The owner can choose to read or listen to a message immediately, or archive it to be retrieved at a later time. AcuraLink® messages consist of a limited amount of text plus expanded details via Text-To-Speech.

Messages that can be sent to the MDX include Maintenance Minder® (detailed information regarding the next required maintenance), Quick Tips (information to help maximize the benefit of MDX features), Feature Guide (supplements to the MDX Owner's Manual) and Diagnostic Info (detailed information and instructions should an onboard system issue arise). The MDX owner has complete control over the types of messages they receive. All AcuraLink® preferences can be set via the Owner Link™ website (www.ahm-ownerlink.com).

AcuraLink® can provide the owner with important information that previously has been unavailable. For example, if a warning light should appear on the MDX instrument panel, AcuraLink® can automatically send a trouble code along with the sensor data associated with the fault to the Acura Telematics Server. The code is analyzed, and a message is sent back to the MDX - such as "A software issue has been detected. It is OK to continue driving. The repair is currently being developed, so you do not need to visit your dealer at this time." A separate AcuraLink® message will be sent to the MDX when it's time to visit the dealer to have the system repaired. AcuraLink® can tell the owner if a particular fault is serious enough to cancel a trip, if it can be dealt with later or if it requires special driving techniques.

ACURALINK REAL-TIME TRAFFIC™

With AcuraLink Real-Time Traffic™, the MDX's navigation screen can display regularly updated traffic information including traffic flow, incidents and construction on freeways in 77 major metropolitan areas. The information is part of the XM NavTraffic® feature (aggregated by NAVTEQ™ from multiple sources including police and highway patrol incident reports and transportation departments). Information is transmitted by XM® satellites to the MDX where it is graphically displayed on the navigation system- with a zoom scale ranging between 1/20-mile to 5-mile increments.

To see details or select traffic incidents, the MDX owner can click on an icon on the map by pushing "Enter" on the interface dial. MDX drivers can avoid congestion en route and choose the fastest path to their destination with traffic information that is continuously updated. The system displays traffic incidents, determines average traffic speed and, if a destination is programmed into the navigation system, estimates travel time along the chosen route. It can automatically recalculate results as factors change. Plus, XM NavTraffic® alerts drivers of scheduled traffic incidents such as construction and road closures, plus unscheduled incidents such as incidents and disabled vehicles.

Traffic Rerouting™ can automatically recalculate a "detour" route and display a pop-up box signifying the route change, when traffic congestion or road incidents are detected along the selected drive route. Alternately, the driver can recalculate a route in manual mode simply by selecting "TRAFFIC INCIDENTS" from the Map Info menu followed by selecting the "AVOID" command relevant to an incident. (Note: Traffic Rerouting™ requires a monthly subscription to the XM NavTraffic® service).

AcuraLink Real-Time Traffic™ with Traffic Rerouting™ gives MDX owners a useful time saving tool on freeways. AcuraLink Real-Time Traffic™ is offered on a subscription basis for a nominal fee following a 3-month free trial period. In addition to the on-screen traffic information, MDX owners who maintain their XM® Radio service also receive more general audio traffic information that runs on a 2-3 minute loop in 77 major metropolitan areas.

ACURALINK REAL-TIME WEATHER™

The ideal complement to AcuraLink Real-Time Traffic™ is the MDX's integrated AcuraLink Real-Time Weather™. In difficult driving conditions, AcuraLink Real-Time Weather™ can provide an up-to-date weather picture.

AcuraLink Real-Time Weather™ was co-developed with XM NavWeather® to provide a weather tracking system for area specific, real-time weather conditions between your current location and a programmed final destination. The system focuses on the specific weather on your personal drive route, rather than just offering general weather conditions for a region. AcuraLink Real-Time Weather™ information is continuously updated and is delivered to the vehicle navigation system via the MDX's built-in XM™ satellite receiver.

AcuraLink Real-Time Weather™ technology is enhanced for specific travel conditions in 21 major metropolitan areas. The information focuses on identifying potential weather threats along with current and future forecast weather conditions. The navigation screen displays current weather conditions in an easy-to-read format. By moving the MDX's navigation system cursor to the desired location on the map you can obtain weather info for a specific location. Press the "Enter" button and information regarding your current location will return.

Unique Threat Matrix Technology within AcuraLink Real-Time Weather™ generates prompts with specific icons (within 46 different categories) that inform the MDX driver if the vehicle is headed into oncoming severe weather- such as a developing snow storm, ice, wind shear or even a tornado warning. Based on this advance information, the MDX driver can choose to reroute before encountering the severe weather. When the display is zoomed out to reveal the entire United States, a radar image map shows current weather patterns across the entire country. AcuraLink Real-Time Weather™ offers 1- or 3-day weather forecasts for specific areas of the United States.

Weather data is provided by Baron Services, Inc., which deciphers a complex array of National Weather Service information to produce the weather information provided to Acura owners. MDX owners receive a complementary 3-month trial subscription that delivers AcuraLink Real-Time Weather™ along with AcuraLink Real-Time Traffic™ and XM® Radio. After the complementary subscription expires, AcuraLink Real-Time Weather™ is available on a monthly subscription basis individually, together with AcuraLink Real-Time Traffic™ or XM® Radio, or as a combined package of all three features.

DVD ENTERTAINMENT SYSTEM (Available with Technology or Advance Package)

The MDX is available with an Entertainment Package that features a rear display screen. With a 9-inch motorized full VGA color screen (with 400-percent improved resolution) mounted in an overhead console, the system provides entertainment for the second and third row passengers. Audio plays through the MDX's speakers in Dolby Digital surround sound, via two wireless Personal Surround headphones, or through three audio jacks. An AUX input jack in rear of the center console is provided for video game play or other inputs. A 115-volt, 100-watt outlet inside the center console to provides power for a video game console, laptop computer or other small electronic device. The system also plays the audio content available from the MDX audio system, complete with on-screen information.

The RES can also operate independently, allowing the rear passengers to enjoy one type of programming, while the front passengers listen to another. The Rear Entertainment System main controls and DVD player are built into the center section of the MDX instrument panel, just below the audio system. An illuminated and removable, wireless remote control is also positioned in the overhead console for easy operation by second- and third-row passengers.

KEYLESS ACCESS SYSTEM

MDX models with the Technology Package or Advance Package have the latest generation of Acura's Keyless Access System. The enhanced system identifies one of two drivers each time the driver's door is opened (even if it is already unlocked) then sets within the MDX's memory a multitude of features to a custom profile preset by that driver. The system sets the driver's seat, steering wheel, outside mirrors, climate control, audio system presets, select navigation system settings and the HandsFreeLink® Profile.

The Keyless Access System also features a unique "quick vent" feature (activated by pressing the Keyless Access Remote "unlock" button two times and then holding it) that automatically lowers all side windows as well as opens the moonroof to quickly vent built-up interior heat. In addition, turning the key in the driver's door key cylinder to the "lock" position twice (and then holding it the second time), simultaneously closes all open windows and the moonroof.

ADVANCE PACKAGE

The 2010 Acura MDX offers an Advance Package that includes all items in the Technology Package and adds:

• Blind spot information system
• Collision Mitigating Braking System™ (CMBS™)
• Adaptive Cruise Control (ACC)
• 19x8-inch 7-spoke aluminum-alloy wheels with performance tires
• Active Damper System (ADS)
• Ventilated front seats (in addition to heat) with perforated Milano premium leather trim and contrast French seam stitching
• Sport steering wheel with unique paddle shifters

ADAPTIVE CRUISE CONTROL (ACC)

The MDX with the Advance Package includes the Collision Mitigating Braking System™ (CMBS™) and Adaptive Cruise Control (ACC). ACC is a vehicle speed and distance control system that uses a grille-mounted millimeter-wave radar unit to monitor the distance between the MDX and the vehicle directly ahead. Like a conventional cruise control system, the MDX's ACC can maintain a pre-set speed. In addition, by combining radar data with data from speed sensors, ACC can regulate the MDX's speed to maintain a pre-set following distance interval between it and the vehicle directly ahead. The system is designed for use on open highways and works only when the MDX is traveling over 25 miles per hour.

Pressing the "ACC" button below the right-hand spoke of the steering wheel activates the system. When this button is pushed, "ACC" will appear on the Multi-Information Display (located between the tachometer and speedometer) indicating that the ACC system has been turned on. To select the ACC cruising speed, the driver accelerates to a chosen speed and presses the "Decel/Set" button located on the right-hand spoke of the steering wheel. Once selected, the cruising speed is shown on the Multi-Information Display.

The following distance interval is selected by pressing the "Distance" button on the lower right spoke of the steering wheel. Using this button, the driver can choose one of three following intervals: approximately 1 second, 1.5 seconds or 2 seconds, based on the speed of the MDX along with the following distance the driver wants to maintain from the car directly ahead. Each time the button is pressed, a "vehicle-shaped" icon on the Multi-information display changes to reflect the chosen following interval:

• One bar representing approximately a 1-second interval
• Two bars representing approximately a 1.5-second interval
• Three bars representing approximately a 2-second interval

Once ACC is activated, the system's electronic control unit (ECU) adjusts the throttle or applies light braking to maintain the chosen following distance interval between the MDX and the vehicle directly in front of it. If a vehicle from another lane cuts in front of the MDX (between the MDX and the car that it has been following) the ACC system will beep and a "vehicle" icon will flash on the Multi-Information Display to alert the driver that a new vehicle has been detected. The ACC system then adjusts the throttle and/or applies braking to maintain the pre-set following interval between the MDX and the new vehicle. A vehicle icon will appear each time a vehicle moves into the ACC system's range. Conversely, when a vehicle moves out of the ACC system's range, the vehicle icon changes to an "outlined" image.

If the vehicle directly ahead of the MDX brakes suddenly, a series of beeps will sound and the word "BRAKE" will appear on the Multi-Information Display warning the driver to apply the brakes. If the vehicle directly in front of the MDX accelerates out of the radar's detection zone or moves to another lane, and another vehicle is not within the system's range, ACC will accelerate the MDX until the pre-set cruising speed is achieved.

When a vehicle moves out of range, the "vehicle icon" on the Multi-Information Display will change from solid to outline. The driver can switch between ACC and conventional cruise control by holding down the "Distance" button located on the steering wheel for five seconds. Cruise control system status is displayed continuously on the Multi-Information Display.

Because rain, snow, fog and other types of inclement weather can affect the ACC system's millimeter-wave radar, the ACC system should not be used during these conditions.

BLIND SPOT INFORMATION SYSTEM

The MDX's available Advance Package includes the blind spot information system. A pair of sensors (one on each rear corner of the vehicle) can detect nearby vehicles that may be positioned in the driver's blind spot. If the MDX's turn signal is on in the direction of a detected blind-spot object, an indicator located on the inside A-pillar garnish flashes to catch the driver's attention.

To prevent false alarms while maneuvering at low speed, the system is disabled below approximately 6 mph. The system can also be manually switched off by the driver using a switch is located on the instrument panel to the left of the steering wheel.

2010 MDX INTERIOR ACCESSORIES

A line of Acura Genuine Accessories was developed simultaneously with the MDX to provide personalization for the Acura owner. Like all Acura Genuine Accessories, the MDX accessories are covered by a 4-year/50,000-mile limited warranty if installed at the time of original vehicles purchase.

CRASH PERFORMANCE TARGETS

The 2010 MDX is expected to receive the highest crash safety ratings (5-star) available from the National Highway Traffic Safety Administration (NHTSA) crash safety tests, and received the highest rollover resistance rating (4-star) given to any SUV. NHTSA crash safety tests include frontal crash and side impact crash tests.

NHTSA test results:

• Frontal Crash, Driver - 5-Star
• Frontal Crash, Passenger - 5-Star
• Rollover Rating - 4-Star

NHTSA expected test results:

• Side-impact Crash, Front seat - 5-Star
• Side-impact Crash, Rear seat - 5-Star

OFFSET REAR COLLISION

The new requirements for NHTSA's FMVSS 301 fuel system integrity standard include a more severe rear crash test. In the current test, a 3,015 pound deformable barrier sled strikes 70-percent of the vehicle's width at 50 mph. In contrast, the prior version of FMVSS 301 used a 4,000 pound flat rigid moving barrier that struck the full width of the vehicle at 30 mph. The new test requires that the vehicle absorb more crash energy than before.

FMVSS 216 ROOF CRUSH

The 2010 MDX is engineered to surpass the existing government roof crush test standard of 1.5 times the curb weight of the vehicle, and is anticipated to meet the upcoming standard of 2.5 times curb weight. Efficient use of high-strength steel creates a body structure with the stiffness to allow such results while still permitting the use of the moonroof.

ADVANCED COMPATIBILITY ENGINEERING™ (ACE™)

Like every other Acura vehicle, the all-new 2010 MDX features Advanced Compatibility Engineering™ (ACE™) unit-body design. ACE™ is an exclusive body design that enhances occupant protection and crash compatibility in frontal crashes. The ACE™ design utilizes a network of connected structural elements to distribute crash energy more evenly throughout the front of the vehicle. This enhanced frontal crash energy management helps to reduce the forces transferred to the passenger compartment and can help to more evenly disperse the forces transferred to other vehicles in a crash.

If the MDX should collide head-on with a smaller and/or lighter vehicle, Advanced Compatibility Engineering™ also helps provide good engagement with the small vehicle's frame. This helps reduce the risk of intrusion while simultaneously helping to disperse the crash energy across a wider area at the front of the vehicle.

IIHS SIDE IMPACT CRASHWORTHINESS EVALUATION (SICE)

The 2010 Acura MDX was designed to achieve a "GOOD" rating in the rigorous IIHS Side Impact Crashworthiness Evaluation (SICE) evaluation, which measures how well a vehicle withstands intrusion from a large SUV in a side collision. The MDX's high-strength steel safety cage, along with the use of high-strength side door beams, help make it resistant to intrusion.

DRIVER AND FRONT PASSENGER DUAL-STAGE, MULTIPLE-THRESHOLD AIRBAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

The MDX is equipped with dual-stage, multiple-threshold front airbags (SRS).. One or both of these airbags will be deployed only in the event of a sufficient frontal impact. If deployed, these airbags are capable of being inflated at different rates depending on crash severity, seatbelt usage and other factors.. Frontal airbags are designed to supplement the seatbelts to help reduce the likelihood of head and upper body injuries in frontal crashes.

Dual-Stage, Multiple-Threshold Airbag Parameters

• Airbag deployment thresholds are controlled depending on the severity of a collision, driver seat position, passenger weight, and the buckle status of both occupants.
• The dual-stage, multiple-threshold strategy applies to front airbags only and does not affect operation of side airbags or side curtain airbags

The MDX airbag system uses a sensor to assess the weight of the front passenger. The front passenger airbag is shut off if the weight sensor indicates that a small child is occupying the front seat. In addition, the driver's seat has a seat position sensor: if the seat is in a more forward position (where the occupant will be close to the airbag), the airbag is fired with a longer delay to reduce the chance of injury caused by the airbag itself. A laser-cut, seamless instrument panel cover fully conceals the instrument panel-mounted passenger airbag while the driver-side front airbag is housed within the steering wheel.

DRIVER AND FRONT PASSENGER KNEE BOLSTERS

To help reduce the likelihood of injuries to the driver or front passenger's legs in a frontal collision, the MDX has energy-absorbing knee bolsters. The bolsters are designed to help dissipate collision forces if the driver or front passenger's legs should contact the lower instrument panel during a frontal collision.

DRIVER AND FRONT PASSENGER SIDE AIRBAGS WITH FRONT PASSENGER OCCUPANT POSITION DETECTION SYSTEM (OPDS)

Side airbags mounted in the outboard area of each MDX front seatback are designed to provide torso and pelvis protection in the event of a side impact. In addition, the front passenger's seat is equipped with Occupant Position Detection System (OPDS), an innovative technology designed to deactivate the side airbag if a child or small-stature adult leans into the side airbag deployment path. When the passenger returns to an upright seating position, the side airbag reactivates so it can deploy to help protect the occupant in a side impact. The unique system utilizes sensors in the passenger seatback to determine the height and position of the occupant. The 2010 MDX's side airbags have a 2-chamber design featuring a stiffer lower chamber to load the pelvis area earlier in the collision, along with a softer upper chamber to help reduce the likelihood of a rib injury.

SIDE CURTAIN AIRBAGS

In a severe side impact or rollover, the MDX's side curtain airbags deploy from roof-mounted modules, to help provide head protection for front and outboard rear occupants. Side curtain airbags effectively cover the side window area from the front to rear seats in both side and rollover impact collisions. Tests show that the g forces acting upon an outboard occupant's head are far lower with side curtain airbags.

FRONT SEAT BELTS WITH AUTOMATIC TENSIONING SYSTEM

The MDX front seat belts have an automatic tensioning system with load limiters to help protect the driver and front passenger in a collision. Research has shown that seat belts that are snugly secured around the occupants provide better protection; thus, in the first few milliseconds of a collision a tensioning system—powered by a small pyrotechnic device—automatically tightens the front seat belts. If deceleration forces rise above a predetermined threshold, a load limiter releases a small length of seat belt webbing to reduce the pressure applied to the occupant. The load limiter system helps reduce the injuries that seat belts can cause in a severe high-speed collision. In addition, the driver's seat belt has a dual-stage load limiter that provides a higher initial load, and then steps down to a lower load after a certain amount of the seat belt spools out. The dual-stage load limiter is specially designed to prevent too much forward driver movement, given the close proximity of the steering wheel.

All MDX seating positions feature 3-point seat belts, and adjustable shoulder belt height is available for front seat passengers. The rear center seat belt buckle stores in a recessed pocket when not in use.

LATCH (LOWER ANCHORS AND TETHERS FOR CHILDREN)

The 2010 MDX includes a LATCH (Lower Anchors and Tethers for CHildren) child-seat mounting system for the outboard rear seating positions. LATCH features built-in lower anchors and ready-to-use tether attachment points that allow compatible child safety seats to be installed without using the vehicle's seat belt system. Additionally, the LATCH system simplifies child-seat installation when an owner installs a LATCH-compatible child seat. The center rear seat position has upper tether anchors only.

ACTIVE FRONT HEAD RESTRAINTS

The 2010 MDX is fitted with active front head restraints designed to help minimize the risk of neck injuries in the event of a rear impact. The head restraint is mechanically linked to a lumbar plate located inside of the front seatback. In a rear impact, the occupant's body pushes against the seatback, causing the head restraint to move forward in a carefully prescribed arc. This motion helps equalize the impact forces transmitted to the head, neck and spine as the occupant's head moves backward during the collision. Effectively managing and dispersing this energy is critical to help minimize the potential for injuries.

VOLUNTARY SAFETY IMPROVEMENTS

As the popularity soared for light trucks (including pickups, crossover vehicles and SUVs) in the last decade, so did the risk of such large vehicles colliding head-on with smaller ones. In light of this risk, engineers of the 2010 Acura MDX designed a front structure that helps minimize the likelihood of over-ride or submarining in frontal collisions between vehicles of disparate size.

Pedestrian Safety
The 2010 Acura MDX makes pedestrian injury mitigation a high priority, and adopts several pedestrian-injury mitigation measures that U.S. law does not require. For example, the MDX hood frame and aluminum hood panel are designed to help protect pedestrians by deforming over a broad area to absorb collision energy. In addition, the hood hinges are designed to bend and the windshield wiper pivots also feature a breakaway design to help reduce the likelihood of injury in the event that a collision with a pedestrian should occur.

Dynamic Rollover
Another target that Acura designers felt strongly about was the MDX's ability to withstand a rollover with the roof frame maintained, no fuel system damage, and no tailgate or tailgate door-opening damage. Though not required or regulated by the government, the high-strength steel safety cage provides the stiffness that allows the MDX to better withstand rollover forces.

STANDARD VEHICLE STABILITY ASSIST™ (VSA®) WITH TRACTION CONTROL AND BRAKE ASSIST

Standard equipment on the 2010 Acura MDX is Vehicle Stability Assist™ (VSA®), an Electronic Stability Control system that enhances controllability while the vehicle is accelerating, braking or cornering, or when the driver makes a sudden maneuver. VSA® has been retuned for 2010 to deliver a 10-percent improvement in performance during hard acceleration on slippery surfaces. The VSA® works in conjunction with the vehicle's drive-by-wire throttle and its 4-channel ABS system to help the vehicle maintain the driver's intended path of travel. It functions by applying brake force to one or more wheels independently while also managing the throttle, ignition and fuel systems to reduce engine power output.

Vehicle Stability Assist™ constantly analyzes data from seven sensors that monitor wheel and vehicle speed, steering input, lateral G-forces and yaw rate, and compares the driver's control inputs with the vehicle's actual response. Whenever the vehicle's actual response falls outside of a predetermined acceptable range, VSA® intervenes with corrective action. If VSA® detects an oversteer condition, the system may apply braking force to the outside front and rear wheels to counteract the unintended yawing effect. Or in the event of understeer, VSA® may apply braking to the inside rear wheel while reducing engine power to help return the car to its intended course.

Vehicle Stability Assist™ is calibrated to work in a nearly transparent manner, meaning that drivers may not even be aware of its operation. Therefore, to keep the driver informed, an indicator light flashes on the instrument panel anytime the system is enhancing vehicle stability. While the driver may deactivate the VSA® and traction-control functions via a switch on the instrument panel, ABS and Brake Assist remain fully operational at all times.

Emergency Braking
Brake Assist, which utilizes some of the VSA® system components, recognizes emergency braking situations and assists the driver to apply maximum braking force to slow the vehicle more quickly. This important system is controlled by special computer logic that determines when the speed and stroke of the brake pedal exceed a typical range—as they would in a panic stop. At this point the modulator pump increases braking pressure to ensure maximum stopping force and help shorten braking distance as much as possible. Brake Assist functions only when the driver is pressing the brake pedal; the additional braking force provided by the system ceases when the driver releases pressure on the brake pedal.

ADVANCED 4-CHANNEL ABS WITH ELECTRONIC BRAKE DISTRIBUTION

The 2010 Acura MDX is equipped with 4-wheel disc brakes and a sophisticated 4-channel/4-sensor anti-lock braking system. The system helps improve active safety by offering a firm brake-pedal feel and a short activation stroke, as well as Electronic Brake Distribution (EBD) circuitry that automatically proportions braking force between the front and rear wheels based on the vehicle's weight distribution. EBD helps maximize braking effectiveness whether the MDX is transporting only the driver, or is fully loaded with passengers and luggage.

TIRE PRESSURE MONITORING SYSTEM (TPMS)

The 2010 Acura MDX has a Tire Pressure Monitoring System (TPMS) that alerts the driver whenever the air pressure in one or more of the tires decreases below a specified level. Using four sensors (one in each tire), TPMS transmits information on tire air pressure to the vehicle's ECU. A low tire pressure indicator located on the instrument panel illuminates when tire pressure drops to a potentially critical level.

FUEL TANK SAFETY

The MDX's 21-gallon fuel tank is positioned in front of the rear body-deformation zone to minimize the risk of damage in a collision. Locating the fuel tank in this protected area optimizes vehicle balance by moving the weight of the fuel tank farther forward. Thus, handling characteristics are minimally affected whether the fuel tank is full or near empty.

COLLISION MITIGATING BRAKING SYSTEM™ (CMBS™)

The MDX Advance Package includes a Collision Mitigating Braking System™ (CMBS™), the first application of this technology on an Acura SUV. This revolutionary safety technology monitors the likelihood of a rear-end collision, and uses audio, visual and tactile signals to alert drivers to the risk of collision. Should the system determine that a collision likely is unavoidable, it applies the MDX's brakes and tensions the front seat belts to help reduce impact force on occupants. Unlike pre-collision systems on competitive vehicles, in certain circumstances CMBS™ automatically applies the brakes to help mitigate the severity of a collision.

Using a millimeter-wave radar unit located inside the front grille, the CMBS™ system monitors the distance between the MDX and the vehicle directly in front of it up to a distance of 300 feet, and tracks the rate of closure between the two vehicles. If the closing rate increases to a point where a collision is likely to occur (based on relative vehicle speeds and following distance), the CMBS™ system uses visual and audible warnings to prompt the driver to take preventative action. Based on the driver's response, the system will disengage if it determines that the likelihood of a collision has decreased to an acceptable level. If the driver's response does not sufficiently reduce the risk of a collision, the CMBS™ system will issue a secondary warning consisting of audible, visual and tactile elements as well as light braking to alert the driver to take action. If the closing rate increases so much that a collision becomes seemingly unavoidable, CMBS™ can initiate hard braking to reduce the vehicle's speed as well as automatically tension the driver and front passenger seat belts to help reduce the severity of the crash. In some circumstance, CMBS will not give any or all warnings before applying the brakes.

The CMBS™ system used in the MDX's Advance Package is similar in concept to the one used on the Acura RL, and its special seat belt retractors replace the standard automatic tensioning system found on the base MDX and the MDX with Technology Package.
