Drive (D) Use this position for your normal driving. The transmis- sion 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.


Automatic Transmission


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.

Driving with the Paddle Shifters


Using the Paddle Shifters in D position (D-Paddle Shift Mode) When you are driving in 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.


To shift up or down, use the (right) or each side of the steering wheel.

Driving with the Paddle Shifters


The automatic transmission will not allow you to shift up or down if:


You downshift before the engine speed falls below the upper limit 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 rises above the lower limit of the higher gear.


You press both paddle shifters at the same time.


You press one of the two paddle shifters with another paddle shifter being pressed.


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 goes out.


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.


298


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).


2009 RDX 08/04/11 18:42:45 31STK620 0304 


Driving with the Paddle Shifters


Using the Paddle Shifters in S position (Sequential Shift Mode) With the shift lever in 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.


GEAR POSITION INDICATOR


‘‘M’’ INDICATOR


When you move the shift lever from ‘‘D’’ to ‘‘S’’ position and pull either paddle shifter, the gear position indicator displays ‘‘M’’ along with the selected gear number.


To upshift, pull the 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.

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. Driving in the higher gear helps fuel economy.


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:


Here are the speed ranges for upshifting and downshifting.


You downshift before the engine speed falls below the upper limit 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 rises above the lower limit of the higher gear.


You try to shift to third or a higher gear when the vehicle is stationary.

Super Handling-All Wheel Drive (SH-AWD ) System The super handling-all wheel drive (SH-AWD) system is a full time all- wheel-drive system that automatically controls and transfers varying amounts of engine torque to all wheels independently, according to the driving conditions.


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.

2009 RDX 08/04/11 18:43:08 31STK620 0307 


Super Handling-All Wheel Drive (SH-AWD ) System


TM


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 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.

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.


If the vehicle is facing uphill, turn the front wheels away from the curb.


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 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.


303


2009 RDX 08/04/11 18:43:26 31STK620 0309 


Braking System


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


384


304


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 effective- ness. 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 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.


2009 RDX 08/04/11 18:43:33 31STK620 0310 


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.


Anti-lock Brakes (ABS)


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 78


).


If the indicator comes on while driving, test the brakes as instructed on page

Anti-lock Brakes (ABS)


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.


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.


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.


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.

. If the brakes feel normal,


Test your brakes as instructed on page 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.

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.


Tire Pressure Monitoring System (TPMS)


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.


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 370


).


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.


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.

307


2009 RDX 08/04/11 18:43:57 31STK620 0313 


Tire Pressure Monitoring System (TPMS)


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 361


).


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 guidelines.

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 mounted inside the tire behind the valve stem. 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.

The vehicle stability assist (VSA) system helps to stabilize the vehicle during cornering if the vehicle turns more or less than desired. 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.

Vehicle Stability Assist (VSA ), aka Electronic Stability Control (ESC), System


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.


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.


VSA is turned on every time you start the engine, even if you turned it off the last time you drove the vehicle.


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

surfaces.


if you plan to tow off paved


Off-Highway section on page


The


Total Trailer Weight: 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.


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.


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.


314


2009 RDX 08/04/11 18:44:57 31STK620 0320 


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.



The maximum


Gross Vehicle Weight Rating (GVWR) allowable weight of the vehicle, all occupants, all accessories, all cargo, and the tongue load is 4,894 lbs (2,220 kg).



The maximum


Gross Axle Weight Ratings (GAWR) allowable weight of the vehicle, all occupants, all accessories, all cargo, and the tongue load must not exceed 2,546 lbs (1,155 kg) on the front axle, and 2,381 lbs (1,080 kg) on the rear axle.



The maximum


Gross Combined Weight Rating (GCWR) allowable weight of the fully loaded vehicle and trailer is 6,394 lbs (2,900
kg)


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.


Towing a Trailer


If you normally pull the same load each time you tow a trailer, you can use a suitable scale or a special tongue load gauge to check the tongue load the first time you set up a towing combination (a fully loaded vehicle and trailer), then recheck the tongue load whenever the conditions change.


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, province, and local regulations.

Towing a Trailer


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.


TrailerBrakes Acura requires that any trailer with a total trailer weight of 1,000 lbs (455
kg) or more have its own brakes.


If you choose electric brakes, be sure they are electronically actuated. Do not attempt to tap into your vehicle’s hydraulic system. No matter how successful it may seem, any attempt to attach trailer brakes to your vehicle’s hydraulic system will lower braking effectiveness and create a potential hazard.


See your trailer dealer or rental agency for more information on installing electric brakes.


TrailerLights Trailer lights and equipment must comply with federal, state/province, and local regulations. Check with your local trailer sales or rental agencies for the requirements in the area where you plan to tow, and use only equipment designed for your vehicle.


316


2009 RDX 08/04/11 18:45:10 31STK620 0322 


Since lighting and wiring vary by trailer type and brand, you should have a qualified technician install a suitable connector between the vehicle and the trailer. Improper equipment or installation can cause damage to your vehicle’s electrical system and affect your vehicle warranty.

AdditionalTowingEquipment Many states and Canadian provinces require special outside mirrors when towing a trailer. Even if they don’t, you should install special mirrors if you cannot clearly see behind you, or if the trailer creates a blind spot.


Ask your trailer sales or rental agency if any other items are recommended or required for your towing situation.

Pre-Tow Checklist When preparing to tow, and before driving away, be sure to check the following:


The vehicle has been properly serviced, and the suspension, cooling system, and lights are in good operating condition.


The trailer has been properly serviced and is in good condition.


All weights and loads are within limits.


The hitch, safety chains, and any other attachments are secure.


All items in or on the trailer are properly secured and cannot shift while you drive.


The lights and brakes on your vehicle and the trailer are working properly.


Your vehicle tires and spare are properly inflated, and the trailer tires and spare are inflated as recommended by the trailer maker.


You may want to fill the fuel tank with premium fuel. Premium fuel provides improved performance.

Driving Safely With a Trailer The added weight, length, and height of a trailer will affect your vehicle’s handling and performance, so driving with a trailer requires some special driving skills and techniques.


For your safety and the safety of others, take time to practice driving maneuvers before heading for the open road, and follow the guidelines in this section.


TowingSpeedsandGears Drive slower than normal in all driving situations, and obey posted speed limits for vehicles with trailers. Use the D position when towing a trailer on level roads. See ‘‘ Hills additional gear information. Do not exceed 55 mph (88 km/h). At higher speeds, the trailer may sway or affect vehicle handling.


’’ in the next column for


Drivingon


MakingTurnsandBraking Make turns more slowly and wider than normal. The trailer tracks a smaller arc than your vehicle, and it can hit or run over something the vehicle misses. Allow more time and distance for braking. Do not brake or turn suddenly as this could cause the trailer to jackknife or turn over.


Towing a Trailer


DrivingonHills When climbing hills, closely watch your temperature gauge (see page 76
). If it nears the H (Hot) mark, turn the A/C off, reduce speed and, if necessary, pull to the side of the road to let the engine cool.


When driving down hills, reduce your speed, and shift down to S position, or use the paddle shifters to the lower gear (3, 2 or 1) in the S position. When towing a trailer, do not ‘‘ride’’ the brakes, and remember, it will take longer to slow down and stop when towing a trailer.

If you must stop when facing uphill, use the foot brake or parking brake. Do not try to hold the vehicle in place by pressing on the accelerator, as this can cause the automatic transmission to overheat.


HandlingCrosswindsandBuffeting Crosswinds and air turbulence caused by passing trucks can disrupt your steering and cause the trailer to sway. When being passed by a large vehicle, keep a constant speed, and steer straight ahead. Do not try to make quick steering or braking corrections.


BackingUp Always drive slowly and have someone guide you when backing up. Grip the wheel; then turn the wheel to the left to get the trailer to move to the left, and turn the wheel right to move the trailer to the right.

Off-Highway Driving Guidelines


Improperly operating this vehicle on or off pavement can cause an accident or rollover in which you and your passengers could be seriously injured or killed.


Follow all instructions and guidelines in this owner’s manual. Keep your speed low, and don’t drive faster than conditions permit.


General Information Your vehicle has been designed primarily for use on pavement. But its higher ground clearance and super handling-all wheel drive (SH-AWD) system allow you to occasionally travel on unpaved roads, to campgrounds, picnic sites, and similar locations. It is not designed for trailblazing, mountain climbing, or other challenging off-road activities.


If you decide to drive on unpaved roads, you will find that it requires somewhat different driving skills. Your vehicle will also handle somewhat differently than it does on pavement. So be sure to read this owner’s manual, pay special attention to the precautions and tips in this section, and get acquainted with your vehicle before you leave the pavement.


Important Safety Precautions To avoid loss of control or rollover, be sure to follow all precautions and recommendations.


Be sure to store cargo properly, and do not exceed your vehicle cargo load limits (see pages 284


and


314


).


Wherever you drive, make sure you and your passengers always wear seat belts.


Keep your speed low, and never go faster than the conditions allow.


It’s up to you to continually assess the situation and drive within the limits.

Off-Highway Driving Guidelines


Accelerating and Braking For better traction on all surfaces, accelerate slowly and gradually build up speed. If you try to start too fast on wet soil, mud, snow, or ice, you might not have enough traction to get underway, and you may dig yourself a hole. Starting with the shift lever in D position will help you have a smoother start on snow or ice.


Keep in mind that you will usually need more time and distance to brake to a stop on unpaved surfaces. Avoid hard braking. Do not ‘‘pump’’ the brakes; let the anti-lock braking system pump them for you.


Check Out Your Vehicle Before you leave the pavement, be sure to do all scheduled maintenance and service, and inspect your vehicle for any problems. Pay special attention to the condition of the tires, and check the tire pressures.


After you return to the pavement, carefully inspect your vehicle to make sure there is no damage that could make driving it unsafe. Recheck the condition of the tires and the tire pressures.


Remember The route presents limits (too steep or bumpy roads). You have limits (driving skill and comfort). And your vehicle has limits (traction, stability, and power).


Driving off-highway can be hazardous if you fail to recognize limits and take the proper precautions.


322


Avoiding Obstacles Debris in the road can damage your suspension or other components. Because your vehicle has a high center of gravity, driving over a large obstacle, or allowing a wheel to drop into a deep hole can cause your vehicle to tip or roll over.


Driving on Slopes If you can’t clearly see all conditions or obstacles on a slope, walk the slope before you drive on it. If you have any doubt whether or not you can safely drive on the slope, don’t do it. Find another route.


If you are driving up a hill and find that you cannot continue, turnaround over. Slowly back down the hill, following the same route you took up the hill.

Off-Highway Driving Guidelines


Crossing a Stream Avoid driving through deep water. If you encounter water in your route (a small stream or large puddle, for example), evaluate it carefully before going ahead. Make sure it is shallow, flowing slowly, and has firm ground underneath. If you are not sure of the depth or the ground, turn around and find another route.


Driving through deep water can also damage your vehicle. The water can get into the transmission and differential, diluting the lubricant and causing an eventual failure. It can also wash the grease out of the wheel bearings.


If You Get Stuck Avoid driving on soft sand, deep mud, or other surfaces where you could get stuck. If you do happen to get stuck because of inclement weather or other conditions, choose a safe and appropriate course of action.


If you spin the wheels excessively trying to get unstuck, you may overheat the components of the SH-AWD system. The SH-AWD indicator on the instrument panel will blink to indicate the rear differential temperature is too high.


You should never use a jack to try getting unstuck. A jack only works on firm, level ground. Also, your vehicle could easily slip off the jack and hurt you or someone else.


You will also see an ‘‘SH-AWD DIFF TEMP HIGH’’ message on the multi- information display (see page ).


78


If this happens, stop and allow everything to cool down. The SH-AWD indicator goes off after the rear differential temperature drops.
