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.

Without touching the accelerator pedal, turn the ignition key to the START (III) position. Do not hold the key in the START (III) position for more than 15 seconds at a time. If the engine does not start right away, pause for at least 10 seconds before trying again.

The immobilizer system protects your vehicle f rom thef t. If an improperly- coded key (or other device) is used, the engine’s f uel system is disabled. For more inf ormation, see page

5.

6.

If the engine does not start within 15 seconds, or starts but stalls right away, repeat step 4 with the accelerator pedal pressed halfway down. If the engine starts, release pressure on the accelerator pedal so the engine does not race.

If the engine fails to start, press the accelerator pedal all the way down, and hold it there while starting to clear flooding. If the engine still does not start, return to step 5.

The engine is harder to start in cold weather. Also, the thinner air f ound at altitudes above 8,000 f eet (2,400
meters) adds to this problem.

Shift Lever Position Indicators

These indicators on the instrument panel show which position the shift lever is in.

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.

Second (2) pull the shift lever towards you, then shift to the lower gear. This position locks the transmission in second gear. It does not downshift to first gear when you come to a stop.

Shifting out of the D position will cancel D3, and cause the D3
indicator to go out. Selecting the D position again will resume D3, and the indicator will come on.

Use second gear:

For more power when climbing.

To increase engine braking when going down steep hills.

Turning the ignition switch to the LOCK (0) position turns D3 off. To use D3 when you restart the engine, select the D position, and press the D3 switch again.

The D3 indicator also comes on for a few seconds when you turn the ignition switch to the ON (II) position.

For starting out on a slippery surface or in deep snow.

First (1) − To shift from second to first, pull the shift lever towards you, then shift to the lower gear. This position locks the transmission in first gear. By upshifting and downshifting through 1, 2, and D, you can operate the transmission much like a manual transmission without a clutch pedal.

If you shift into first position when the vehicle speed is above 28 mph (45 km/h), the transmission shifts into second gear first to avoid sudden engine braking.

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.

Remove the key from the shift lock release slot, then reinstall the cover. Make sure the notch on the cover is on the instrument panel side. 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.

Your vehicle is equipped with a variable torque management 4-wheel-drive system (VTM-4) that distributes engine torque to the appropriate drive axle depending on the available traction conditions. The system is completely automatic, always active, and does not require any driver interaction.

206

2008 Ridgeline ０７／０４／２７　１４：０８：４４　３１ＳＪＣ６２０　０２１２　

VTM-4 System

If you become stuck, you can activate the VTM-4 by pressing the VTM-4 LOCK button while in first (1), second (2), or reverse (R) gear below 18 mph (30 km/h). This mode overrides the auto system to send maximum torque to the rear axle. This mode is only intended for intermittent use at low speed to free your vehicle if it becomes stuck or when you encounter a steep grade with one wheel on a slippery surface. Generally, you should first allow the auto mode to operate to adjust for the available traction conditions.

To Engage the VTM-4 Lock: 1.

The vehicle speed must be below 18 mph (30 km/h).

2.

Move the shift lever to first (1), second (2), or reverse (R) gear.

3.

Press the VTM-4 LOCK button. The indicator in the button comes on.

To get unstuck, apply light pressure to the accelerator pedal. Do not spin the front tires for more than a few seconds. Because of the amount of torque applied to the rear tires, they should not spin. This is normal. If you are not able to move the vehicle, stop and reverse direction.

The VTM-4 Lock will temporarily disengage when the vehicle speed exceeds 18 mph (30 km/h). The indicator in the button will remain on.

To Disengage the VTM-4 Lock, any of the following:

Press the VTM-4 LOCK button.

do

Move the shift lever to D.

Turn the ignition switch to the LOCK (0) position.

Do not use the VTM-4 LOCK button on dry, paved roads. Driving on dry, paved roads with VTM-4 Lock ON may damage the rear dif f erential when making a turn. Strange noise and vibration can also result.

Do not continuously spin the f ront tires of your vehicle. Continuously spinning the f ront tires can cause transmission or rear dif f erential damage.

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 (not including the spare tire). 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 indicator and the appropriate tire on the tire pressure monitor to come on.

Low Tire Pressure Indicator

When the low tire pressure 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, and inflate the tire to the recommended pressure shown on the driver’s doorjamb.

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 276

).

If you cannot make the low tire pressure indicator go out after inflating the tires to the specified values, have your dealer check the system as soon as possible.

208

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 indicator may come on unexpectedly.

2008 Ridgeline ０７／０４／２７　１４：０９：０２　３１ＳＪＣ６２０　０２１４　

Tire Pressure Monitoring System (TPMS)

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 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 indicator will not come on if the tires are overinflated.

Refer to page guidelines.

267

for tire inflation

Although your tire pressure is monitored, you must manually check the tire pressures monthly.

Each tire, including the spare, should be checked monthly when cold and set to the recommended inflation pressure as specified in the vehicle placard and this owner’s manual (see page

268

).

Tire Pressure Monitor

The appropriate tire indicator and low tire pressure indicator comes on if a tire becomes significantly Low Tire underinflated. See Pressure Indicator on page

208

Tire Pressure Monitoring System (TPMS) Indicator This indicator comes on and stays on if there is a problem with the tire pressure monitoring system.

If this happens, the system will shut off and no longer monitor tire pressures. Have the system checked by your dealer as soon as possible.

If the low tire pressure indicator or TPMS indicator comes on, the VSA system automatically turns on even when the VSA system is turned off by pressing the VSA OFF switch (see page cannot turn the VSA system off by pressing the VSA off switch again.

). If this happens, you

Tire Pressure Monitoring System (TPMS)

The low tire pressure indicator or the TPMS indicator will go off when you replace the spare tire with the specified regular tire equipped with the tire pressure monitor sensor.

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.

).

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.

After you replace the flat tire with the spare, the TPMS indicator stays on. This is normal; the system is not monitoring the spare tire pressure. Manually check the spare tire pressure to be sure it is correct.

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 (if equipped) and the windows are closed.

Turn off the lights.

Place any packages, valuables, etc. in the cargo area in your vehicle or the In-Bed Trunk, or take them with you.

Lock the doors.

Onvehicleswithsecuritysystem Check the indicator on the driver’s door to verify that the security system is set.

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.

Parking

If the vehicle is facing uphill, turn the front wheels away from the curb, and set the parking brake.

If the vehicle is facing downhill, turn the front wheels toward the curb, and set the parking brake.

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.

211

2008 Ridgeline ０７／０４／２７　１４：０９：２５　３１ＳＪＣ６２０　０２１７　

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 the 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 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.

Braking System

Your vehicle is equipped with disc brakes at all four wheels. A power assist helps reduce the effort needed on the brake pedal. The emergency brake assist system increases the stopping force when you depress the brake pedal hard in an emergency situation. The anti-lock brake system (ABS) helps you retain steering control when braking very hard.

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.

212

2008 Ridgeline ０７／０４／２７　１４：０９：３２　３１ＳＪＣ６２０　０２１８　

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.

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.’’

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.

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

292

CONTINUED

213

2008 Ridgeline 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. Slow down, and allow a greater distance between vehicles under those conditions.

０７／０４／２７　１４：０９：３９　３１ＳＪＣ６２０　０２１９　

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.

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.

292

. 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.

The VSA indicator will come on along with the ABS indicator.

Vehicle Stability Assist (VSA) System

VSA Activation Indicator

When VSA activates, you will see the VSA activation indicator blink (see page

67

).

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.

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.

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.

If the low tire pressure indicator or TPMS indicator comes on, the VSA system automatically turns on even when the VSA system is turned off by pressing the VSA OFF switch (see page cannot turn the VSA system off by pressing the VSA off switch again.

). If this happens, you

Vehicle Stability Assist (VSA) System

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.

216

VSA and Tire Sizes Driving with varying tire or wheel sizes may cause the VSA to malfunction. When replacing tires, make sure they are of the same size and type as your original tires (see page

271

).

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.

This switch is above the parking brake release handle. Press it to turn the VSA system on and off.

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.

Hitch AllmodelsexceptRTX We strongly recommend that you have your dealer install a class 3
hitch. Using non-Honda equipment may result in serious damage to your vehicle.

Your dealer offers an optional trailer package for models other than RTX. The package includes a hitch, a ball mount, and a wiring harness.

Read the trailer manufacturer’s instructions, and select the appropriate draw bar for the height of the trailer you will be towing.

Discuss any additional needs with your trailer sales or rental agency, and make sure all equipment is properly installed, maintained, and also meets state, federal, province, and local regulations.

WeightDistributingHitch A weight distributing hitch is not recommended for use with your vehicle, as an improperly adjusted weight distributing hitch may reduce handling, stability, and braking performance.

Towing a Trailer

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

There are two common types of trailer brakes: surge and electric. Surge brakes are common for boat trailers, since the brakes will get wet.

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 manufacturer for more information on installing electric brakes.

222

Use this illustration to identify each terminal in the trailer brake controller connector.

STOP (WHITE/BLACK)

A factory installed, 4-pin gray connector is located under the instrument panel near the top of the parking brake pedal. This connector has all of the circuits required to install most electric trailer brake controllers. A jumper harness to adapt your electric trailer brake controller to the vehicle is included with the optional Genuine Honda trailer hitch kit. To obtain a trailer hitch kit, see your dealer.

Have a qualified mechanic install your trailer brake controller following the trailer brake controller manufacturer’s instructions. Failure to properly install the trailer brake controller may increase the distance it takes for you to stop your vehicle when towing a trailer.

Towing a Trailer

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.

SwayControl This device is recommended if your trailer tends to sway. Your trailer maker can tell you what kind of sway control you need and how to install it.

TrailerMirrors Many states and provinces require special exterior 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.

SpareTires When towing a trailer, we recommend that you carry a full-size spare wheel and tire for your vehicle and trailer. See page for proper for how to store a tire size, page full size wheel and tire, and page 277

Towing a Trailer

Your vehicle tires and spare are in good condition and properly inflated.

The trailer tires and spare are in good condition and inflated as recommended by the trailer maker.

Towing performance can be affected by high altitude, high temperature, or when climbing steep grades. Therefore, premium fuel (premium unleaded gasoline with pump octane number of 91 or higher) is recommended when towing more than 3,500 lbs (1,590
kg).

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 below.

Break-InPeriod Avoid towing a trailer during your vehicle’s first 600 miles (1,000 km).

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 tires, brakes, 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 on and in the trailer are properly secured and cannot shift while you drive.

Towing a Trailer

TowingSpeedsandGears Drive slower than normal in all driving situations, and obey posted speed limits for vehicles with trailers. When towing a fixed-sided trailer (e.g., camper), do not exceed 55 mph (88 km/h). At higher speeds, the trailer may sway or affect vehicle handling.

When towing a trailer on level roads under normal driving conditions, do not use D3. This will increase the automatic transmission fluid temperature and may cause overheating.

With heavy cargo on the pickup bed, your vehicle has a higher center of gravity. Drive slowly and cautiously, and allow more time and distance for braking. Loading heavy cargo could affect your vehicle’s handling and performance.

230

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.

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.

Allow more time and distance for braking. Do not brake or turn suddenly as this could cause the trailer to jackknife or turn over.

DrivingonHills When climbing hills, closely watch your temperature gauge. If it nears the red (Hot) mark, turn the air conditioning 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 use D3. Do not Remember, it ‘‘ride’’ the brakes. takes longer to slow down and stop when towing a trailer.

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.

Parking When parking on level ground, follow all normal precautions (see page ) including putting the transmission in Park, and firmly setting the parking brake.

211

Do not park on an incline unless it is unavoidable. If you must park on an incline, follow the steps below to help prevent the vehicle and trailer from rolling and possibly injuring someone.

1.

3.

Turn the front wheels toward the curb on a downhill, and away from the curb on an uphill.

With the foot brake fully pressed, have someone place wheel chocks on the downhill side of the vehicle and trailer wheels.

Firmly apply the parking brake before you put the transmission in Park. This keeps the vehicle from putting pressure on the parking mechanism in the transmission. It also makes it easier to move the shift lever out of Park when you want to drive away.

Off-Highway Driving Guidelines

General Information Your vehicle has been designed primarily for use on pavement. But its higher ground clearance and four- wheel drive VTM-4 system allow you to occasionally travel on unpaved roads and surfaces. Your vehicle 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. Be sure to pay extra attention to the precautions and tips in this section, and get acquainted with your vehicle before leaving the pavement.

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.

232

2008 Ridgeline ０７／０４／２７　１４：１２：１７　３１ＳＪＣ６２０　０２３８　

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 cargo load limits (see page

and

191

217

).

Be aware that a heavy load can reduce ground clearance and your ability to clear obstacles.

Whenever 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

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.

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.

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 second (2) gear 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.

Avoiding Obstacles Your vehicle is not equipped with undercarriage guards to protect key components, so take care to avoid rocks, tree stumps, and other obstacles in your path.

Because your vehicle has a higher center of gravity than a conventional passenger vehicle, driving a wheel over a tall object, or allowing a wheel to drop into a deep hole, can cause your vehicle to tip or roll over.

234

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 Before driving through water, stop, get out if necessary, and make sure that:

The banks and surface under the water provide good traction. The water may hide hazards such as rocks, holes, or mud.

The water is not deep enough to cover your wheel hubs, axles, or exhaust pipe. You could stall and not be able to restart your engine. The water can also damage important vehicle components.

The banks are sloped so you can drive out.

The water is not flowing too fast. Deep rushing water can sweep you downstream. Even very shallow rushing water can wash the ground from under your tires and cause you to lose traction and possibly roll over.

If you decide it is safe to drive through water, choose a suitable speed, and proceed without shifting, changing speeds, stopping, or shutting off the engine.

Do not try to cross water at high speeds, as this may cause severe damage to the cooling system or result in loss of control.

After driving through water, test your brakes. If they got wet, gently ‘‘pump’’ them while driving slowly until they operate normally.

If the water is deeper than the wheel hubs, some additional service may be required. This service is not covered by your warranties.

If You Get Stuck If you get stuck, and cannot get unstuck with the VTM-4 system,
