{WARNING:
When you are driving off-road, bouncing and
quick changes in direction can easily throw you
out of position. This could cause you to lose
control and crash. So, whether you are driving on
or off the road, you and your passengers should
wear safety belts.
Scanning the Terrain
Off-road driving can take you over many different kindsof terrain. Be familiar with the terrain and its manydifferent features.
Surface Conditions :Off-roading surfaces can behard-packed dirt, gravel, rocks, grass, sand, mud, snow,or ice. Each of these surfaces affects the vehicle'ssteering, acceleration, and braking in different ways.Depending on the surface, slipping, sliding, wheelspinning, delayed acceleration, poor traction, andlonger braking distances can occur.
Surface Obstacles :Unseen or hidden obstacles canbe hazardous. A rock, log, hole, rut, or bump can startleyou if you are not prepared for them. Often theseobstacles are hidden by grass, bushes, snow, or eventhe rise and fall of the terrain itself.
Some things to consider:
.Is the path ahead clear?
.Will the surface texture change abruptly up ahead?
.Does the travel take you uphill or downhill?
.Will you have to stop suddenly or change directionquickly?
When driving over obstacles or rough terrain, keep afirm grip on the steering wheel. Ruts, troughs, or othersurface features can jerk the wheel out of your hands.
When driving over bumps, rocks, or other obstacles, thewheels can leave the ground. If this happens, even withone or two wheels, you cannot control the vehicle aswell or at all.
Because you will be on an unpaved surface, it isespecially important to avoid sudden acceleration,sudden turns, or sudden braking.
Off-roading requires a different kind of alertness fromdriving on paved roads and highways. There are noroad signs, posted speed limits, or signal lights. Usegood judgment about what is safe and what is not.

Driving Uphill
Once you decide it is safe to drive up the hill:
.Use a low gear and get a firm grip on thesteering wheel.
.Get a smooth start up the hill and try to maintainspeed. Not using more power than needed canavoid spinning the wheels or sliding.
{WARNING:
Turning or driving across steep hills can be
dangerous. You could lose traction, slide
sideways, and possibly roll over. You could be
seriously injured or killed. When driving up hills,
always try to go straight up.
.Try to drive straight up the hill if at all possible.If the path twists and turns, you might want to findanother route.
.Ease up on the speed as you approach the top ofthe hill.
.Attach a flag to the vehicle to be more visible toapproaching traffic on trails or hills.
.Sound the horn as you approach the top of the hillto let opposing traffic know you are there.
.Use headlamps even during the day to make thevehicle more visible to oncoming traffic.
{WARNING:
Driving to the top (crest) of a hill at full speed can
cause an accident. There could be a drop-off,
embankment, cliff, or even another vehicle. You
could be seriously injured or killed. As you near
the top of a hill, slow down and stay alert.
If the vehicle stalls, or is about to stall, and you cannotmake it up the hill:
.Push the brake pedal to stop the vehicle andkeep it from rolling backwards and apply theparking brake.
.If the engine is still running, shift the transmissionto R (Reverse), release the parking brake, andslowly back down the hill in R (Reverse).
6-19
Page 410 of 616
.If the engine has stopped running, you need torestart it. With the brake pedal pressed and theparking brake still applied, shift the transmissionto P (Park) and restart the engine. Then, shift toR (Reverse), release the parking brake, andslowly back down the hill as straight as possiblein R (Reverse).
.While backing down the hill, put your left handon the steering wheel at the 12 o'clock positionso you can tell if the wheels are straight and canmaneuver as you back down. It is best to backdown the hill with the wheels straight rather thanin the left or right direction. Turning the wheel toofar to the left or right will increase the possibilityof a rollover.
Things not to do if the vehicle stalls, or is about to stall,when going up a hill:
.Never attempt to prevent a stall by shifting intoN (Neutral) to rev-up the engine and regain forwardmomentum. This will not work. The vehicle can rollbackward very quickly and could go out of control.
.Never try to turn around if about to stall whengoing up a hill. If the hill is steep enough to stallthe vehicle, it is steep enough to cause it to rollover. If you cannot make it up the hill, back straightdown the hill.
If, after stalling, you try to back down the hill and decideyou just cannot do it, set the parking brake, put yourtransmission in P (Park), and turn off the engine. Leavethe vehicle and go get some help. Exit on the uphill sideand stay clear of the path the vehicle would take if itrolled downhill.
Driving Downhill
When off-roading takes you downhill, consider:
.How steep is the downhill? Will I be able tomaintain vehicle control?
.What is the surface like? Smooth? Rough?Slippery? Hard-packed dirt? Gravel?
.Are there hidden surface obstacles? Ruts? Logs?Boulders?
.What is at the bottom of the hill? Is there a hiddencreek bank or even a river bottom with largerocks?
If you decide you can go down a hill safely, try to keepthe vehicle headed straight down. Use a low gear soengine drag can help the brakes so they do not have todo all the work. Descend slowly, keeping the vehicleunder control at all times.
6-20
Page 411 of 616
{WARNING:
Heavy braking when going down a hill can cause
your brakes to overheat and fade. This could
cause loss of control and a serious accident.
Apply the brakes lightly when descending a
hill and use a low gear to keep vehicle speed
under control.
Things not to do when driving down a hill:
.When driving downhill, avoid turns that take youacross the incline of the hill. A hill that is not toosteep to drive down might be too steep to driveacross. The vehicle could roll over.
.Never go downhill with the transmission inN (Neutral), called free-wheeling. The brakes willhave to do all the work and could overheatand fade.
Vehicles are much more likely to stall when going uphill,but if it happens when going downhill:
1. Stop the vehicle by applying the regular brakesand apply the parking brake.
2. Shift to P (Park) and, while still braking, restartthe engine.
3. Shift back to a low gear, release the parking brake,and drive straight down.
4. If the engine will not start, get out and get help.
6-21

Stalling on an Incline
{WARNING:
Getting out on the downhill (low) side of a vehicle
stopped across an incline is dangerous. If the
vehicle rolls over, you could be crushed or killed.
Always get out on the uphill (high) side of the
vehicle and stay well clear of the rollover path.
If the vehicle stalls when crossing an incline, be sureyou, and any passengers, get out on the uphill side,even if the door there is harder to open. If you get outon the downhill side and the vehicle starts to roll over,you will be right in its path.
If you have to walk down the slope, stay out of the paththe vehicle will take if it does roll over.
Driving in Mud, Sand, Snow, or Ice
When you drive in mud, snow, or sand, the wheelsdo not get good traction. Acceleration is not asquick, turning is more difficult, and braking distancesare longer.
It is best to use a low gear when in mud—thedeeper the mud, the lower the gear. In really deep mud,keep the vehicle moving so it does not get stuck.
When driving on sand, wheel traction changes.On loosely packed sand, such as on beaches orsand dunes, the tires will tend to sink into the sand.This affects steering, accelerating, and braking.Drive at a reduced speed and avoid sharp turns orabrupt maneuvers.
Hard packed snow and ice offer the worst tire traction.On these surfaces, it is very easy to lose control. Onwet ice, for example, the traction is so poor that you willhave difficulty accelerating. And, if the vehicle does getmoving, poor steering and difficult braking can cause itto slide out of control.
{WARNING:
Driving on frozen lakes, ponds, or rivers can be
dangerous. Underwater springs, currents under
the ice, or sudden thaws can weaken the ice. Your
vehicle could fall through the ice and you and your
passengers could drown. Drive your vehicle on
safe surfaces only.
6-23

Driving in Water
{WARNING:
Driving through rushing water can be dangerous.
Deep water can sweep your vehicle downstream
and you and your passengers could drown. If it is
only shallow water, it can still wash away the
ground from under your tires, and you could lose
traction and roll the vehicle over. Do not drive
through rushing water.
Heavy rain can mean flash flooding, and flood watersdemand extreme caution.
Find out how deep the water is before driving throughit. Do not try it if it is deep enough to cover the wheelhubs, axles, or exhaust pipe—you probably will not getthrough. Deep water can damage the axle and othervehicle parts.
If the water is not too deep, drive slowly through it.At faster speeds, water splashes on the ignition systemand the vehicle can stall. Stalling can also occur if youget the tailpipe under water. If the tailpipe is underwater, you will never be able to start the engine. Whengoing through water, remember that when the brakesget wet, it might take longer to stop. SeeDriving in Rainand on Wet Roads on page 6!25.
After Off-Road Driving
Remove any brush or debris that has collectedon the underbody, chassis, or under the hood.These accumulations can be a fire hazard.
After operation in mud or sand, have the brake liningscleaned and checked. These substances can causeglazing and uneven braking. Check the body structure,steering, suspension, wheels, tires, and exhaust systemfor damage and check the fuel lines and cooling systemfor any leakage.
The vehicle requires more frequent service due tooff-road use. Refer to the Maintenance Schedule foradditional information.
Driving at Night
Night driving is more dangerous than day drivingbecause some drivers are likely to be impaired—byalcohol or drugs, with night vision problems, or byfatigue.
Night driving tips include:
.Drive defensively.
.Do not drink and drive.
.Reduce headlamp glare by adjusting the insiderearview mirror.

4. Reapply the brake pedal. Then apply the parkingbrake and shift into P (Park).
5. Release the brake pedal.
{WARNING:
It can be dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the parking
brake firmly set. The vehicle can roll.
If the engine has been left running, the vehicle
can move suddenly. You or others could be
injured. To be sure the vehicle will not move, even
when on fairly level ground, always put the shift
lever fully in P (Park) with the parking brake
firmly set.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
2. Start the engine
3. Shift into a gear
4. Release the parking brake
5. Let up on the brake pedal.
6. Drive slowly until the trailer is clear of the chocks.
7. Stop and have someone pick up and storethe chocks.
Maintenance When Trailer Towing
The vehicle needs service more often when pulling atrailer. See this manual's Maintenance Schedule orIndex for more information. Things that are especiallyimportant in trailer operation are automatic transmissionfluid, engine oil, axle lubricant, belts, cooling systemand brake system. It is a good idea to inspect thesebefore and during the trip.
Check periodically to see that all hitch nuts and boltsare tight.

4. With the coolant surge tank pressure cap off, startthe engine and let it run until you can feel theupper radiator hose getting hot. Watch out for theengine cooling fan.
By this time, the coolant level inside the coolantsurge tank may be lower. If the level is lower, addmore of the proper mixture to the coolant surgetank until the level reaches the FULL COLD mark.
5. Replace the pressure cap. Be sure the pressurecap is hand-tight and fully seated.
6. Verify coolant level after engine is shut off and thecoolant is cold. If necessary, repeat coolant fillprocedure Steps 1 through 6.
Notice:If the pressure cap is not tightly installed,coolant loss and possible engine damage mayoccur. Be sure the cap is properly and tightlysecured.
Engine Overheating
The vehicle has several indicators to warn of engineoverheating.
There is a coolant temperature gage on your vehicle'sinstrument panel. SeeEngine Coolant TemperatureGage on page 4!35.
In addition, ENGINE OVERHEATED STOP ENGINE,ENGINE OVERHEATED IDLE ENGINE, and a ENGINEPOWER IS REDUCED message comes on in the DriverInformation Center (DIC) on the instrument panel. SeeDIC Warnings and Messages on page 4!48.
You may decide not to lift the hood when this warningappears, but instead get service help right away. SeeRoadside Service on page 9!8.

Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radioand sensor technology to check tire pressure levels.The TPMS sensors monitor the air pressure in yourvehicle's tires and transmit tire pressure readings to areceiver located in the vehicle.
Each tire, including the spare (if provided), should bechecked monthly when cold and inflated to the inflationpressure recommended by the vehicle manufactureron the vehicle placard or tire inflation pressure label.(If your vehicle has tires of a different size than the sizeindicated on the vehicle placard or tire inflation pressurelabel, you should determine the proper tire inflationpressure for those tires.)
As an added safety feature, your vehicle has beenequipped with a tire pressure monitoring system(TPMS) that illuminates a low tire pressure telltale whenone or more of your tires is significantly under!inflated.
Accordingly, when the low tire pressure telltaleilluminates, you should stop and check your tires assoon as possible, and inflate them to the properpressure. Driving on a significantly under!inflated tirecauses the tire to overheat and can lead to tire failure.Under!inflation also reduces fuel efficiency and tiretread life, and may affect the vehicle's handling andstopping ability.
Please note that the TPMS is not a substitute for propertire maintenance, and it is the driver's responsibility tomaintain correct tire pressure, even if under!inflationhas not reached the level to trigger illumination of theTPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMSmalfunction indicator to indicate when the system isnot operating properly. The TPMS malfunction indicatoris combined with the low tire pressure telltale. Whenthe system detects a malfunction, the telltale will flashfor approximately one minute and then remaincontinuously illuminated. This sequence will continueupon subsequent vehicle start!ups as long as themalfunction exists.
When the malfunction indicator is illuminated, thesystem may not be able to detect or signal low tirepressure as intended. TPMS malfunctions may occurfor a variety of reasons, including the installation ofreplacement or alternate tires or wheels on the vehiclethat prevent the TPMS from functioning properly.Always check the TPMS malfunction telltale afterreplacing one or more tires or wheels on your vehicle toensure that the replacement or alternate tires andwheels allow the TPMS to continue to function properly.
SeeTire Pressure Monitor Operationon page 7!68foradditional information.

TPMS Sensor Matching Process
Each TPMS sensor has a unique identification code.Any time you rotate your vehicle's tires or replace oneor more of the TPMS sensors, the identification codeswill need to be matched to the new tire/wheel position.The sensors are matched to the tire/wheel positionsin the following order: driver side front tire, passengerside front tire, passenger side rear tire, and driverside rear tire using a TPMS diagnostic tool. See yourdealer/retailer for service.
The TPMS sensors can also be matched to each tire/wheel position by increasing or decreasing the tire's airpressure. If increasing the tire's air pressure, do notexceed the maximum inflation pressure indicated on thetire's sidewall.
To decrease air-pressure out of a tire you can use thepointed end of the valve cap, a pencil-style air pressuregage, or a key.
You have two minutes to match the first tire/wheelposition, and five minutes overall to match all four tire/wheel positions. If it takes longer than two minutes, tomatch the first tire and wheel, or more than five minutesto match all four tire and wheel positions the matchingprocess stops and you need to start over.
The TPMS sensor matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with theengine off.
3. PressQandKon the Remote Keyless Entry
(RKE) transmitter at the same time forapproximately five seconds. The horn sounds twiceto signal the receiver is in relearn mode and TIRELEARNING ACTIVE message displays on the DICscreen.
4. Start with the driver side front tire.
