Fuel economy is not a fixed number. It varies based on driving conditions, driving habits and vehicle condition. Therefore, it is not possible for one set of estimates to predict fuel economy precisely for all drivers in all environments. The EPA fuel economy estimates shown in the example to the right are a useful tool for comparison when buying a vehicle. EPA estimates include: City MPG － Represents urban driving in a vehicle in light traffic. A range of miles per gallon achieved is also provided. Highway MPG － Represents a mixture of rural and interstate driving, in a warmed-up vehicle, typical of longer trips in free-flowing traffic. A range of miles per gallon achieved is also provided. 358 City MPG Highway MPG Combined Fuel Economy Estimated Annual Fuel Cost (Sample U.S. EPA label shown) Combined Fuel Economy － Represents a combination of city and highway driving. The scale represents the range of combined fuel economy for other vehicles in the class. Estimated Annual Fuel Cost － Provides an estimated annual fuel cost, based on 15,000 miles (20,000 km) per year multiplied by the cost per gallon (based on EPA fuel cost data) divided by the combined fuel economy. For more information on fuel economy ratings and factors that affect fuel economy, visit www.fueleconomy.gov (Canada: Visit www.vehicles.gc.ca) 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Fuel Economy Factors The following factors can lower your vehicle's fuel economy: ● Aggressive driving (hard acceleration and braking) ● Excessive idling, accelerating and braking in stop-and-go traffic ● Cold engine operation (engines are more efficient when warmed up) ● Driving with a heavy load or the air conditioner running ● Improperly inflated tires Improving Fuel Economy VehicleMaintenance A properly maintained vehicle maximizes fuel economy. Poor maintenance can significantly reduce fuel economy. Always maintain your vehicle according to the maintenance messages displayed on the information display (see Owner's Maintenance Checks on page 417). For example: ● Use the required engine oil (see page 420). ● Maintain proper tire inflation － An underinflated tire increases ‘‘rolling resistance,’’ which reduces fuel economy. ● Avoid carrying excess weight in your vehicle － It puts a heavier load on the engine, increasing fuel consumption. Fuel Economy ● Keep your vehicle clean － In particular, a build-up of snow or mud on your vehicle's underside adds weight and rolling resistance. Frequent cleaning helps your fuel economy. CONTINUED 359 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu ● Always drive in the highest gear possible － If your vehicle has a manual transmission, you can boost your fuel economy by up shifting as early as possible. ● Avoid excessive idling － Idling results in 0 miles per gallon (0 kms per liter). ● Minimize the use of the air conditioning system － The A/C puts an extra load on the engine which makes it use more fuel. Use the fresh-air ventilation when possible. ● Plan and combine trips － Combine several short trips into one. A warmed-up engine is more fuel efficient than a cold one. Fuel Economy DriveEfficiently ● Drive moderately － Rapid acceleration, abrupt cornering, and hard braking increase fuel consumption. ● Observe the speed limit － Aerodynamic drag has a big effect on fuel economy at speeds above 45 mph (75 km/h). Reduce your speed and you reduce the drag. Trailers, car top carriers, roof racks and bike racks are also big contributors to increased drag. 360 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Calculating Fuel Economy MeasuringTechniques Direct calculation is the recommended source of information about your actual fuel economy. Using frequency of fill-ups or taking fuel gauge readings are NOT accurate measures of fuel economy. Fuel economy may improve over the first several thousand miles. CheckingYourFuelEconomy Fuel Economy Miles driven Gallons of fuel Miles per Gallon 100 Liter Kilometers L per 100 km 1)Fill the fuel tank until the nozzle automatically clicks off. 2)Reset trip counter to zero. 3)Record the total gallons (liters) needed to refill. 4)Follow one of the simple calculations above. 361 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Accessories and Modifications Modifying your vehicle, or installing some non-Acura accessories, can make your vehicle unsafe. Before you make any modifications or add any accessories, be sure to read the following information. Accessories Your dealer has Acura accessories that allow you to personalize your vehicle. These accessories have been designed and approved for your vehicle, and are covered by warranty. Although non-Acura accessories may fit on your vehicle, they may not meet factory specifications, and could adversely affect your vehicle's handling, stability, and reliability. Improper accessories or modifications can affect your vehicle's handling, stability, and performance, and cause a crash in which you can be hurt or killed. Follow all instructions in this owner's manual regarding accessories and modifications. When properly installed, cellular phones, alarms, two-way radios, and low-powered audio systems should not interfere with your vehicle's computer controlled systems, such as your airbags, anti-lock brakes, and tire pressure monitoring system. Before installing any accessory: ● Make sure the accessory does not obscure any lights, or interfere with proper vehicle operation or performance. ● Be sure electronic accessories do not overload electrical circuits (see page 469) or interfere with proper operation of your vehicle. ● Before installing any electronic accessory, have the installer contact your dealer for assistance. If possible, have your dealer inspect the final installation. ● Do not install accessories on the side pillars or across the rear windows. Accessories installed in these areas may interfere with proper operation of the side curtain airbags. 362 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Modifying Your Vehicle Removing parts from your vehicle, or replacing components with non- Acura components could seriously affect your vehicle's handling, stability, and reliability. Here are some examples: ● Lowering the vehicle with a non- Acura suspension kit that significantly reduces ground clearance can allow the undercarriage to hit speed bumps or other raised objects, which could cause the airbags to deploy. ● Raising your vehicle with a non- Acura suspension kit can affect the handling, stability, and reliability. ● Non-Acura wheels, because they are a universal design, can cause excessive stress on suspension components and will not be compatible with the tire pressure monitoring system (TPMS). ● Larger or smaller wheels and tires can interfere with the operation of your vehicle's anti-lock brakes and other systems. ● Modifying your steering wheel or any other part of your vehicle's safety features can make the systems ineffective. If you plan to modify your vehicle, consult your dealer. Accessories and Modifications 363 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Carrying Cargo DOOR LINING POCKETS FRONT DOOR POCKET CARGO HOOKS CENTER POCKET CARGO AREA SEAT BACK POCKETS GLOVE BOX CONSOLE COMPARTMENT 364 Your vehicle has several convenient storage areas: ● Glove box ● Front door pockets ● Door lining pockets ● Seat-back pockets ● Center pocket ● Console compartment ● Cargo area, including the rear seats when folded down. ● Roof-rack (if equipped) However, carrying too much cargo, or improperly storing it, can affect your vehicle's handling, stability, stopping distance, and tires, and make it unsafe. Before carrying any type of cargo, be sure to read the following pages. 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Load Limits The maximum load for your vehicle is 870 lbs (395 kg). See Tire And Loading Information label attached to the driver's doorjamb. Label Example Overloading or improper loading can affect handling and stability and cause a crash in which you can be hurt or killed. Follow all load limits and other loading guidelines in this manual. This figure includes the total weight of all occupants, cargo, and accessories, and the tongue load if you are towing a trailer. Carrying Cargo Steps for Determining Correct Load Limit － 1. Locate the statement ‘‘The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.’’ on your vehicle's placard. 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle. 3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs. 4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the ‘‘XXX’’ amount equals 1,400 lbs. and there will be five 150 lb. passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs. (1,400－750 (5╳150)＝650 lbs.) CONTINUED 365 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Carrying Cargo 5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4. 6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle. 366 Example 1 Example 2 Example 3 Max Load Passenger Weight Cargo Weight (870 lbs) (395 kg) (150 lbs x 2 = 300 lbs) (68 kg x 2 = 136 kg) (570 lbs) (259 kg) Max Load Passenger Weight Cargo Weight (870 lbs) (395 kg) (150 lbs x 4 = 600 lbs) (68 kg x 4 = 272 kg) (270 lbs) (123 kg) Max Load Passenger Weight Cargo Weight (870 lbs) (395 kg) (150 lbs x 5 = 750 lbs) (68 kg x 5 = 340 kg) (120 lbs) (55 kg) In addition, the total weight of the vehicle, all occupants, accessories, cargo, and trailer tongue load must not exceed the Gross Vehicle Weight Rating (GVWR) or the Gross Axle Weight Rating (GAWR). Both are on a label on the driver's doorjamb. 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Carrying Cargo Carrying Cargo in the Passenger Compartment ● Store or secure all items that could be thrown around and hurt someone during a crash. ● Be sure items placed on the floor behind the front seats cannot roll underneath and interfere with the proper operation of the seats, the sensors under the seats, or the driver's ability to operate the pedals. ● If you fold the rear seats down, tie down items that could be thrown about the vehicle during a crash or sudden stop. Also, keep all cargo below the bottom of the windows. If it is higher, it could interfere with the proper operation of the side curtain airbags. ● Keep the glove box closed while driving. If it is open, a passenger could injure their knees during a crash or sudden stop. ● Do not put any items on top of the cargo area cover. They can block your view and be thrown around the vehicle during a crash. Carrying Cargo in the Cargo Area or on a Roof Rack ● Distribute cargo evenly on the floor of the cargo area, placing the heaviest items on the bottom and as far forward as possible. Tie down items that could be thrown about the vehicle during a crash or sudden stop. ● If you fold the rear seats down, tie down items that could be thrown about the vehicle during a crash or sudden stop. Keep all cargo below the bottom of the windows. If it is higher, it could interfere with the proper operation of the side curtain airbags. CONTINUED 367 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Carrying Cargo ● If you carry large items that prevent you from closing the tailgate, exhaust gas can enter the passenger area. To avoid the possibility of carbon monoxide poisoning, follow the instructions on page 57. ●● If you carry any items on a roof rack, be sure the total weight of the rack and the items does not exceed 110 lbs (50 kg). 368 Cargo Hooks/Hanger Bars The hanger bars can be used to hang items. The hanger bar is designed to hang light items (maximum load: 11 lbs or 5 kg on each side). Heavy items may damage the bars. HANGER BARS HOOK To secure the cargo, you can use the four cargo hooks in the cargo area. The illustration shows the location of each cargo hook. The cargo hooks on the floor can be used to install the cargo net for securing items. 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Optional Cargo Net The cargo net can be used to help hold down light items in the cargo area. The cargo net may not prevent heavy items from being thrown forward in a crash or a sudden stop. Heavy items should be secured to the cargo area floor with the hooks or cinch straps attached to the cargo hooks.

It also provides good visibility so you can anticipate problems earlier. Because your vehicle rides higher off the ground, it has a high center of gravity that can cause it to roll over if you make abrupt turns. Utility vehicles have a significantly higher roll over rate than other types of vehicles. To prevent rollovers or loss of control: ● Take corners at slower speeds than you would with a passenger vehicle. ● Avoid sharp turns and abrupt maneuvers whenever possible. ● Do not modify your vehicle in any way that would raise the center of gravity. ● Do not carry heavy cargo on the roof. Your vehicle is equipped with a super handling-all wheel drive (SH-AWD) system. When the system senses a loss of one or more wheel traction, it automatically transfers some power to the other wheels. This gives you better traction and mobility. You still need to exercise the same care when accelerating, steering, and braking that you would in a two- wheel drive vehicle. Seepage405foroff-highwaydriving guidelines. 372 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu You should do these checks and adjustments before you drive your vehicle: 1. Make sure all windows, mirrors, and outside lights are clean and unobstructed. Remove frost, snow, or ice. 2. Check that the hood is fully closed. 3. Visually check the tires. If a tire looks low, use a gauge to check its pressure. 4. Check that any items you may be carrying are stored properly or fastened down securely. 5. Check the seat adjustment (see page 134). 6. Check the adjustment of the inside and outside mirrors (see page 146). 7. Check the steering wheel adjustment (see page 122). 8. Make sure the doors and the tailgate are securely closed and locked. 9. Fasten your seat belt. Check that your passengers have fastened their seat belts (see page 15). Preparing to Drive 10. When you start the engine, check the gauges and indicators in the instrument panel, and the messages on the multi-information display (see pages 63, 73 and 74). 373 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Starting the Engine Your vehicle's starting system has an auto control mode. When you turn the ignition switch to the START (III) position, this feature keeps the engine's starter motor running until the engine starts. Follow these instructions to start the engine: 1. Apply the parking brake. 2. In cold weather, turn off all electrical accessories to reduce the drain on the battery. 3. Make sure the shift lever is in Park. Press on the brake pedal. 374 4. Without touching the accelerator pedal, turn the ignition switch to the START (III) position, then release the ignition switch. You do not need to hold the ignition switch in the START (III) position to start the engine. The starter motor can run for up to 9 seconds to guarantee starting when the outside temperature is very low. If you hold the ignition switch in the START (III) position for more than 7 seconds, the starter motor, depending on the outside temperature, runs for up to 25 seconds until the engine starts. If the engine does not start, wait at least 10 seconds before trying again. The immobilizer system protects your vehicle from theft. If an improperly coded key (or other device) is used, the engine's fuel system is disabled. For more information, see page 124. The engine is harder to start in cold weather. Also, the thinner air found at altitudes above 8,000 feet (2,400 meters) adds to this problem. 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Your vehicle has an electric vacuum pump located in the engine compartment. When you drive in cold weather or thinner air at high altitude, the electric vacuum pump operates more frequently after the engine is started. When the electric vacuum pump is in operation, it makes some mechanical noises come from the engine compartment. This is normal. Starting the Engine Check Starter System Message Canada U.S. If there is a problem with the starter system, you will see a ‘‘CHECK STARTER SYSTEM’’ message on the multi-information display when the ignition switch is turned to the ON (II) position. You will also see this message when the auto control mode of the starter system has a problem. If this message is on, the ignition switch has to be held in the START (III) position manually until the engine starts. The ignition switch can be held in that position up to 15 seconds. Even though you may be able to start the engine manually without the auto control mode of the starter system, have your dealer inspect your vehicle. 375 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Automatic Transmission Shift Lever Position Indicators These indicators on the instrument panel show which position the shift lever is in. 376 The ‘‘D’’ indicator comes on for a few seconds when you turn the ignition switch to the ON (II) position. If it flashes while driving (in any shift position), it indicates a possible problem in the transmission. If the malfunction indicator lamp comes on along with the ‘‘D’’ indicator, there is a problem with the automatic transmission control system. Avoid rapid acceleration, and have the transmission checked by your dealer as soon as possible. When the ‘‘D’’ indicator warns of a possible problem with the transmission, you will see a ‘‘CHECK TRANSMISSION’’ message on the multi-information display (see page 80). Shifting SHIFT LEVER RELEASE BUTTON To shift from Park to any position, press firmly on the brake pedal and press the release button on the front of the shift lever, then pull the lever. You cannot shift out of Park when the ignition switch is in the LOCK (0) or the ACCESSORY (I) position. 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu To shift from: Do this: Press the brake pedal, and press the shift lever release button. Press the shift lever release button. Move the shift lever. P to R R to P N to R D to S S to D D to N N to D R to N Automatic Transmission Reverse (R) － Press the brake pedal and press the release button on the front of the shift lever to shift from Park to reverse. To shift from reverse to neutral, come to a complete stop, and then shift. Press the release button before shifting into reverse from neutral. Neutral (N) － Use neutral if you need to restart a stalled engine, or if it is necessary to stop briefly with the engine idling. Shift to the Park position if you need to leave your vehicle for any reason. Press on the brake pedal when you are moving the shift lever from neutral to another gear. Park (P) － This position mechanically locks the transmission. Use Park whenever you are turning off or starting the engine. To shift out of Park, you must press on the brake pedal and have your foot off the accelerator pedal. Press the release button on the front of the shift lever to move it. If you have done all of the above and still cannot move the lever out of Park, see Shift Lock Release on page 379. To avoid transmission damage, come to a complete stop before shifting into Park. You must also press the release button to shift into Park. The shift lever must be in Park before you can remove the key from the ignition switch. CONTINUED 377 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu With the shift lever in D or S, you can also use the paddle shifters to shift the transmission up or down. Once you begin to use the paddle shifters in S, the transmission will no longer upshift or downshift automatically. For more information of driving with the paddle shifters, see page 380. Engine Speed Limiter If you exceed the maximum speed for the gear you are in, the engine speed will enter into the tachometer's red zone. If this occurs, you may feel the engine cut in and out. This is caused by a limiter in the engine's computer controls. The engine will run normally when you reduce the rpm below the red zone. Automatic Transmission Drive (D) － Use this position for your normal driving. The transmission automatically adjusts to keep the engine at the best speed for the driving conditions. S Position (S) － To shift into the S position, press the release button on the front of the shift lever, and move the lever to S. This position is similar to D, except only gears from first to fourth are selected. The S position keeps the transmission from cycling between fourth and fifth gears in stop-and-go driving. 378 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Shift Lock Release This allows you to move the shift lever out of Park if the normal method of pushing on the brake pedal and pressing the release button does not work. 1. Set the parking brake. 2. Remove the key from the ignition switch. 3. Put a cloth on the notch of the shift lock release slot cover to prevent scratches. Using a small flat-tip screwdriver or a metal fingernail file, carefully pry on the notch of the cover to remove it. Automatic Transmission COVER NOTCH KEY 4. Insert the key in the shift lock release slot. 5. Push down on the key while you press the release button on the shift lever and move the shift lever out of Park to neutral. RELEASE BUTTON SHIFT LOCK RELEASE SLOT 6. Remove the key from the shift lock release slot, then install the cover. Make sure the notch on the cover is on the rear. Insert the key back into the ignition switch, press the brake pedal, and restart the engine. If you need to use the shift lock release, it means your vehicle is developing a problem. Have it checked by your dealer 379 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Driving with the Paddle Shifters Using the Paddle Shifters in the D position (D-Paddle Shift Mode) When you are driving in the D position, pulling either paddle shifter switches from the ordinary automatic transmission [drive mode (D)] to the D-paddle shift mode. You can shift the transmission up or down manually with the paddle shifters. Downshifting gives you more power when climbing, and provides engine braking when going down a steep hill. 380 To shift up or down, use the ＋ (right) or － (left) paddle shifter on either side of the steering wheel. GEAR POSITION INDICATOR Each time you pull ＋ (right), the transmission shifts to a higher gear. Pull － (left) to downshift. You will see the selected gear number on the instrument panel. When you pull either paddle shifter, the gear position indicator shows you the selected gear number. 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu The transmission control system monitors the accelerator pedal use and your driving conditions. When you press the accelerator pedal as in normal driving, the system judges that you are driving at a constant cruising speed without using the paddle shifters. Under these conditions, D-paddle shift mode is canceled, and the transmission automatically returns to drive mode (D). When the transmission returns to drive mode (D), the displayed gear number disappears. The transmission remains in the selected gear if you do not accelerate. Each time you pull either paddle shifter, the transmission shifts one gear up or down. If you want to shift up or down more than two gears, pull the paddle shifter twice, pause, and then pull it again. Driving with the Paddle Shifters The automatic transmission will not allow you to shift up or down if: ● You downshift before the engine speed reaches the highest threshold of the lower gear. If you try to do this, the gear position indicator will flash the number of the lower gear several times, then return to a higher gear. ● You upshift before the engine speed reaches the lowest threshold of the higher gear. ● You pull both paddle shifters at the same time. ● You pull one of the two paddle shifters while continuously pulling on the other one. The transmission downshifts to first gear and returns to drive mode (D) when the vehicle comes to a complete stop or the vehicle speed is about 6 mph (10 km/h). If there is a problem in the transmission while you are driving with the paddle shifters, the D indicator flashes, the D-paddle shift mode is canceled, and the transmission returns to drive mode (D). CONTINUED 381 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Driving with the Paddle Shifters GEAR POSITION INDICATOR ‘‘M’’ INDICATOR When you move the shift lever from ‘‘D’’ to ‘‘S’’ and pull either paddle shifter, the gear position indicator displays ‘‘M’’ along with the selected gear number. To upshift, pull the ＋ (right) paddle shifter. To downshift, pull the － (left) paddle shifter. When you accelerate from a stop, the transmission starts in first gear, and you must manually upshift between first and fifth gears. Make sure you upshift before the engine speed reaches the tachometer's red zone. The transmission remains in the selected gear (5, 4, 3, 2, or 1). There is no automatic downshift when you push the accelerator pedal to the floor. When you are driving in 4th or 5th gear, the transmission downshifts to the lower gear under the following conditions: ● The vehicle slows down to a certain speed. ● You press the brake pedal. Using the Paddle Shifters in the S position (Sequential Shift Mode) With the shift lever in the S position, you can select the sequential shift mode to shift gears; much like a manual transmission using the paddle shifters, but without a clutch pedal. To enter the sequential shift mode, press the release button on the front of the shift lever, move the lever to the S position, then pull either paddle shifter. To cancel the sequential shift mode and return to the ordinary automatic transmission, move the shift lever from the S position. When moving the shift lever, be careful not to operate incorrectly. While you are driving in the sequential shift mode, the transmission will not automatically return to ordinary automatic transmission. 382 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Driving with the Paddle Shifters Downshifting with the paddle shifter allows you to increase the engine braking when going down steep or long hills, and provides more power when climbing uphills. You can upshift the transmission manually to reduce the rpm. The transmission also shifts automatically as the vehicle comes to a complete stop. It downshifts to first gear when the vehicle speed reaches 6 mph (10 km/h) or less. The automatic transmission will not allow you to shift up or down if: ● You downshift before the engine speed reaches the highest threshold of the lower gear. If you try to do this, the gear position indicator will flash the number of the lower gear several times, then return to a higher gear. ● You upshift before the engine speed reaches the lowest threshold of the higher gear. ● You try to shift to third or a higher gear when the vehicle is stationary. ● You pull both paddle shifters at the same time. ● You pull one of the two paddle shifters while continuously pulling on the other one. StartinginSecondGear When you are in sequential shift mode, and the vehicle is stopped, pull the ＋ (right) paddle shifter to shift to second gear. You will see ‘‘M2’’ in the display. Starting in second gear helps to reduce wheelspin in deep snow or on a slippery surface.

While the SH-AWD system helps to enhance the vehicle's driving stability in all situations, it is still your responsibility to drive and corner at reasonable speeds and to leave a sufficient margin of safety. SH-AWD Torque Distribution Monitor TORQUE INDICATOR TORQUE INDICATOR The SH-AWD torque distribution monitor on the multi-information display shows you the amount of torque being sent to the wheels. Each wheel － right front (RF), left front (LF), right rear (RR), and left rear (LR) － has its own torque indicator. 384 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Super Handling-All Wheel Drive™ (SH-AWD®) System Each torque indicator is displayed as a bar graph divided into 5 segments. The number of segments represents the amount of torque distributed to each wheel. When there is only a slight change in torque distribution while driving, such as cruising on level roads at the same speed, the torque distribution monitor may stop displaying the amount of torque. This is not a system problem. The monitor will show the amount if the system senses any change in torque distribution. If the SH-AWD indicator blinks while driving, it indicates the differential temperature is too high. You will also see an ‘‘SH-AWD DIFF TEMP HIGH’’ message on the multi- information display. If this happens, pull to the side of the road when it is safe, shift to Park, and let the engine idle until the indicator goes out. If the indicator does not go out, take your vehicle to a dealer to have it checked. If the SH-AWD indicator on the instrument panel stays on, and the ‘‘CHECK SH-AWD SYSTEM’’ message also appears on the multi- information display, there is a problem with the SH-AWD system. Your vehicle still has normal front- wheel drive with vehicle stability assist (VSA), but does not have the advantages of SH-AWD. Have your vehicle checked by a dealer as soon as possible. 385 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Parking Always use the parking brake when you park your vehicle. Make sure the parking brake is set firmly, or your vehicle may roll if it is parked on an incline. Set the parking brake before you put the transmission in Park. This keeps the vehicle from moving and putting pressure on the parking mechanism in the transmission. Parking Tips ● Make sure the moonroof and the windows are closed. ● Turn off the lights. ● Place any packages, valuables, etc. in the cargo area or take them with you. ● Lock the doors and the tailgate. ● Never park over dry leaves, tall grass, or other flammable materials. The hot three way catalytic converter could cause these materials to catch on fire. ● If the vehicle is facing uphill, turn the front wheels away from the curb. ● If the vehicle is facing downhill, turn the front wheels toward the curb. ● Check the indicator on the instrument panel to verify that the security system is set. ● Make sure the parking brake is fully released before driving away. Driving with the parking brake partially set can overheat or damage the rear brakes. 386 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Your vehicle is equipped with disc brakes at all four wheels. A power assist using negative pressure generated by the engine and the electric vacuum pump helps reduce the effort needed on the brake pedal. The anti-lock brake system (ABS) helps you retain steering control when braking very hard. When the electric vacuum pump is in operation, it makes some mechanical noises come from the engine compartment. This is normal. When you drive in cold weather or thinner air at high altitude, the electric vacuum pump operates more frequently after the engine is started. For more information about the electric vacuum pump, see page 468. Resting your foot on the pedal keeps the brakes applied lightly, builds up heat, and reduces their effectiveness and reduces brake pad life. In addition, fuel economy can be reduced. It also keeps your brake lights on all the time, confusing drivers behind you. Constant application of the brakes when going down a long hill builds up heat and reduces their effectiveness. Use the engine to assist the brakes by taking your foot off the accelerator and downshifting to a lower gear. Check your brakes after driving through deep water. Apply the brakes moderately to see if they feel normal. If not, apply them gently and frequently until they do. Be extra cautious and alert in your driving. Braking System Braking System Design The hydraulic system that operates the brakes has two separate circuits. Each circuit works diagonally across the vehicle (the left-front brake is connected with the right-rear brake, etc.). If one circuit should develop a problem, you will still have braking at two wheels. Brake Pad Wear Indicators All four brakes have audible brake wear indicators. If the brake pads need replacing, you will hear a distinctive, metallic screeching sound when you apply the brake pedal. If you do not have the brake pads replaced, they will screech all the time. It is normal for the brakes to occasionally squeal or squeak when you apply them. 387 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Anti-lock Brakes (ABS) The anti-lock brake system (ABS) helps prevent the wheels from locking up, and helps you retain steering control by pumping the brakes rapidly, much faster than a person can do it. The electronic brake distribution (EBD) system, which is part of the ABS, also balances the front-to-rear braking distribution according to vehicle loading. Youshouldneverpumpthebrakepedal. Let the ABS work for you by always keeping firm, steady pressure on the brake pedal. This is sometimes referred to as ‘‘stomp and steer.’’ You will feel a pulsation in the brake pedal when the ABS activates, and you may hear some noise. This is normal: it is the ABS rapidly pumping the brakes. On dry pavement, you will need to press on the brake pedal very hard before the ABS activates. However, you may feel the ABS activate immediately if you are trying to stop on snow or ice. ABS Indicator If this indicator comes on, the anti- lock function of the braking system has shut down. The brakes still work like a conventional system, but without anti-lock. You should have your dealer inspect your vehicle as soon as possible. You will also see a ‘‘CHECK ABS SYSTEM’’ message on the multi- information display (see page 80). If the indicator comes on while driving, test the brakes as instructed on page 467. 388 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu If the ABS indicator and the brake system indicator come on together, and the parking brake is fully released, the EBD system may also be shut down. Test your brakes as instructed on page 467. If the brakes feel normal, drive slowly and have your vehicle repaired by your dealer as soon as possible. Avoid sudden hard braking which could cause the rear wheels to lock up and possibly lead to a loss of control. Important Safety Reminders ABS does not reduce the time or distance it takes to stop the vehicle. It only helps with the steering control during braking. ABS will not prevent a skid that results from changing direction abruptly, such as trying to take a corner too fast or making a sudden lane change. Always drive at a safe speed for the road and weather conditions. ABS cannot prevent a loss of stability. Always steer moderately when you are braking hard. Severe or sharp steering wheel movement can still cause your vehicle to veer into oncoming traffic or off the road. Anti-lock Brakes (ABS) A vehicle with ABS may require a longer distance to stop on loose or uneven surfaces, such as gravel or snow, than a vehicle without anti- lock. 389 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Tire Pressure Monitoring System (TPMS) Your vehicle is equipped with a tire pressure monitoring system (TPMS) that turns on every time you start the engine and monitors the pressure in your tires while driving. Each tire has its own pressure sensor. If the air pressure of a tire becomes significantly low, the sensor in that tire immediately sends a signal that causes the low tire pressure/TPMS indicator in the instrument panel to come on. If this happens, you will see which tire is losing pressure on the multi- information display along with a ‘‘CHECK TIRE PRESSURE’’ message. Low Tire Pressure/TPMS Indicator When the low tire pressure/TPMS indicator is on, one or more of your tires is significantly underinflated. You should stop and check your tires as soon as possible, and inflate them to the proper pressure as indicated on the vehicle's tire information placard. It is possible that the pressures shown on the multi-information display and the pressures you manually measure are slightly different. If the difference is significant or you cannot make the low tire pressure/ TPMS indicator and message on the multi-information display go out after inflating the tires to the specified values, have your dealer check the system as soon as possible. If you think you can safely drive a short distance to a service station, proceed slowly to the station, then inflate the tire to the recommended pressure. If the tire is flat, or if the tire pressure is too low to continue driving, replace the tire with the compact spare tire (see page 454). Driving on a significantly under- inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Because tire pressure varies by temperature and other conditions, the low tire pressure/TPMS indicator may come on unexpectedly. 390 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu For example, if you check and fill your tires in a warm area, then drive in extremely cold weather, the tire pressure will be lower than measured and could be underinflated and cause the low tire pressure/ TPMS indicator to come on. Or, if you check and adjust your tire pressure in cooler conditions, and drive into extremely hot conditions, the tire may become overinflated. However, the low tire pressure/ TPMS indicator will not come on if the tires are overinflated. Refer to page 444 for tire inflation guidelines. If there is a problem with the TPMS, this indicator begins to flash. It stops flashing after approximately 1 minute, then stays on. You will also see a ‘‘CHECK TPMS SYSTEM’’ message on the multi-information display (see page 393). Tire Pressure Monitoring System (TPMS) Tire Pressure Monitor Although your tire pressure is monitored, you must manually check the tire pressures monthly. Each tire, including the spare, should be checked monthly when the vehicle is cold, and set to the recommended inflation pressure as specified on the vehicle placard and in the owner's manual (see page page 445). INFO BUTTON To select the tire pressure monitor, press the INFO button several times with the ignition switch in the ON (II) position. You will see the above display on the multi-information display when all tire pressures are normal.

The display changes as shown above. Each tire pressure is shown in PSI (U.S. models) or in kPa (Canadian models). 392 This shows that front left tire is losing pressure. Each tire has its own pressure sensor. If the air pressure of a tire becomes significantly low, the sensor in that tire immediately sends a signal that causes the low tire pressure/TPMS indicator in the instrument panel to come on. If this happens, you will see which tire is losing pressure on the multi- information display along with a ‘‘CHECK TIRE PRESSURE’’ message. When any of the tires have low pressure, the tire pressure monitor shows a ‘‘TIRE PRESS. ERROR SYSTEM FUNC NORMAL’’ message. When you continue driving after installing the spare tire, you will also see this message on the multi- information display. 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Tire Pressure Monitoring System (TPMS) TPMS System Failure If there is a problem with the TPMS, the tire pressure monitor shows a ‘‘SYSTEM FUNCTION ERROR’’ message and the tire pressure readings are not displayed. If this happens, you will first see a system warning message ‘‘CHECK TPMS SYSTEM’’ on the multi-information display. If there is a problem with the TPMS, you will see the above message on the multi-information display. If you see this message, the system is off and is not monitoring the tire pressures. Have the system checked by your dealer as soon as possible. Also, the low tire pressure/TPMS indicator begins to flash (see page page 71). If the low tire pressure/TPMS indicator comes on, or the multi- information display shows a ‘‘CHECK TPMS SYSTEM’’ message, the VSA system automatically turns on even when the VSA system is turned off by pressing the VSA OFF switch (see page 396). If this happens, you cannot turn the VSA system off by pressing the VSA OFF switch again. When you restart the vehicle with the compact spare tire, the TPMS system message will also be displayed on the multi-information display after several miles (kilometers) driving.

Replace the indicated flat tire with the compact spare tire (see page 454). After the flat tire is replaced with the spare tire, the low tire pressure/ TPMS indicator stays on while driving. After several miles (kilometers) driving, this indicator begins to flash, then stays on again. You will also see a ‘‘CHECK TPMS SYSTEM’’ message on the multi- information display. This is normal; the system cannot monitor the spare tire pressure. Manually check the spare tire pressure to be sure it is correct. This indicator and the warning message on the multi-information display will go off, after several miles (kilometers) driving, when the spare tire is replaced with the specified regular tire equipped with the tire pressure monitor sensor. Each wheel is equipped with a tire pressure sensor. You must use TPMS specific wheels. It is recommended that you always have your tires serviced by your dealer or a qualified technician. Never use a puncture-repairing agent in a flat tire. If used, you will have to replace the tire pressure sensor. Have the flat tire repaired by your dealer as soon as possible.

It also assists you in maintaining traction while accelerating on loose or slippery road surfaces. It does this by regulating the engine's output and by selectively applying the brakes. When VSA activates, you may notice that the engine does not respond to the accelerator in the same way it does at other times. There may also be some noise from the VSA hydraulic system. You will also see the VSA activation indicator blink. The VSA system cannot enhance the vehicle's driving stability in all situations and does not control your vehicle's entire braking system. It is still your responsibility to drive and corner at reasonable speeds and to leave a sufficient margin of safety. VSA Activation Indicator When VSA activates, you will see the VSA activation indicator blink (see page 69). Vehicle Stability Assist (VSA) System Indicator If this indicator comes on while driving, pull to the side of the road when it is safe, and turn off the engine. Reset the system by restarting the engine. If the VSA system indicator stays on or comes back on while driving, have the VSA system inspected by your dealer. NOTE: The main function of the VSA system is generally known as Electronic Stability Control (ESC). The system also includes a traction control function. If the indicator does not come on when the ignition switch is turned to the ON (II) position, there may be a problem with the VSA system. Have your dealer inspect your vehicle as soon as possible. You will also see a ‘‘CHECK VSA SYSTEM’’ message on the multi- information display if there is a problem with the VSA system. If the low tire pressure/TPMS indicator comes on (see page 390), or the multi-information display shows a ‘‘CHECK TPMS SYSTEM’’ message with the indicator flashing (see page 393), the VSA system automatically turns on even if the VSA system is turned off with the VSA OFF switch. In this case, you cannot turn the VSA system off by pressing the VSA OFF switch again. CONTINUED 395 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Vehicle Stability Assist (VSA®), aka Electronic Stability Control (ESC), System VSA and Tire Sizes Driving with varying tire or wheel sizes may cause the VSA to malfunction. When replacing tires, make sure they are the same size and type as your original tires (see page 448). If you install winter tires, make sure they are the same size as those that were originally supplied with your vehicle. Exercise the same caution during winter driving as you would if your vehicle was not equipped with VSA. Without VSA, your vehicle will have normal braking and cornering ability, but it will not have VSA traction and stability enhancement. VSA OFF Switch In certain unusual conditions when your vehicle gets stuck in shallow mud or fresh snow, it may be easier to free it with the VSA temporarily switched off. When the VSA system is off, the traction control system is also off. You should only attempt to free your vehicle with the VSA off if you are not able to free it when the VSA is on. Immediately after freeing your vehicle, be sure to switch the VSA on again. We do not recommend driving your vehicle with the VSA and traction control systems switched off. 396 VSA OFF SWITCH This switch is under the driver's side vent. To turn the VSA system on and off, press and hold it until you hear a beep. When VSA is off, the VSA activation indicator comes on as a reminder. Press and hold the switch again. It turns the system back on. VSA is turned on every time you start the engine, even if you turned it off the last time you drove the vehicle. 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Your vehicle has been designed primarily to carry passengers and their cargo. You can also use it to tow a trailer if you carefully observe the load limits, use the proper equipment, and follow the guidelines in this section. Break-InPeriod Avoid towing a trailer during your vehicle's first 600 miles (1,000 km) (see page 352). Towing a Trailer Be sure to read the Off-Highway Driving Guidelines section on page 405 if you plan to tow off paved surfaces. Load Limits Exceeding any load limit or improperly loading your vehicle and trailer can cause a crash in which you can be seriously hurt or killed. Check the loading of your vehicle and trailer carefully before starting to drive. Total Trailer Weight: The maximum allowable weight of the trailer and everything in or on it must not exceed 1,500 lbs (680 kg). Towing a load that is too heavy can seriously affect your vehicle's handling and performance. It can also damage the engine and drivetrain. CONTINUED 397 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Towing a Trailer To achieve a proper tongue load, start by loading 60% of the load toward the front of the trailer and 40% toward the rear, then re-adjust the load as needed. Gross Vehicle Weight Rating (GVWR) － The maximum allowable weight of the vehicle, all occupants, all accessories, all cargo, and the tongue load is : 4WD: 4,894 lbs (2,220 kg) 2WD: 4,718 lbs (2,140 kg) Gross Axle Weight Ratings (GAWR) － The maximum allowable weight of the vehicle axle is : 4WD: 2,546 lbs (1,155 kg) on the front axle 2,381 lbs (1,080 kg) on the rear axle 2WD: 2,447 lbs (1,110 kg) on the front axle 2,271 lbs (1,030 kg) on the rear axle Gross Combined Weight Rating (GCWR) － The maximum allowable weight of the fully loaded vehicle and trailer is : 4WD: 6,394 lbs (2,900 kg) 2WD: 4,718 lbs (2,140 kg) Tongue Load: The weight that the tongue of a fully-loaded trailer puts on the hitch should be approximately 10% of the total trailer weight. Too much tongue load reduces front-tire traction and steering control. Too little tongue load can make the trailer unstable and cause it to sway. 398 2011 RDX10/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu Towing a Trailer Towing Equipment and Accessories Towing can require a variety of equipment, depending on the size of your trailer, how it will be used, how much load you are towing, and where you tow. Discuss your needs with your trailer sales or rental agency, and follow the guidelines in this section. Also make sure that all equipment is properly installed and maintained, and that it meets federal, state, provincial, territorial and local regulations. Hitches Any hitch used on your vehicle must be properly bolted to the underbody. SafetyChains Always use safety chains when you tow a trailer. Make sure the chains are secured to the trailer and hitch, and that they cross under the tongue and can catch the trailer if it becomes unhitched. Leave enough slack to allow the trailer to turn corners easily, but do not let the chains drag on the ground. Checking Loads The best way to confirm that all loads are within limits is to check them at a public scale. For public scales in your area, check your local phone book, or contact your trailer dealer or rental agency for assistance. If you cannot get to a public scale, you can estimate the total trailer weight by adding the weight of your trailer (as quoted by the manufacturer) with everything in or on the trailer.
