Avoid driving at excessive speed. Thiscauses vehicle momentum to work againstyou and your vehicle could become stuckto the point that assistance may berequired from another vehicle. Remember,you may be able to back out the way youcame if you proceed with caution.
DRIVING THROUGH MUD ANDWATER
WARNING: Do not spin the wheelsat over 34 mph (55 km/h). The tires mayfail and injure a passenger or bystander.
Mud
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud. Even four-wheel drive vehicles canlose traction in slick mud. If your vehicledoes slide, steer in the direction of the slideuntil you regain control of your vehicle.After driving through mud, clean off residuestuck to rotating driveshafts and tires.Excess mud stuck on tires and rotatingdriveshafts can cause an imbalance thatcould damage drive components.
Water
If you must drive through high water, driveslowly. Traction or brake capability maybe limited. When driving through water,determine the depth and avoid waterhigher than the bottom of the hubs. If theignition system gets wet, your vehicle maystall. Once through water, test the brakes.Wet brakes do not stop your vehicle aseffectively as dry brakes. Drying improvesby applying light pressure to the brakepedal while moving slowly.
Note:Driving through deep water maydamage the transmission. If the front or rearaxle is submerged in water, the axlelubricant and transfer case lubricant shouldbe checked and changed if necessary.
DRIVING ON HILLY OR SLOPINGTERRAIN
Although natural obstacles may make itnecessary to travel diagonally up or downa hill or steep incline, you should try to drivestraight up or straight down.
Note:Avoid turning on steep slopes or hills.A danger lies in losing traction, slippingsideways and possible vehicle roll over.Whenever driving on a hill, determinebeforehand the route you can use. Do notdrive over the crest of a hill without seeingwhat conditions are on the other side. Donot drive in reverse over a hill without theaid of an observer.
When climbing a steep slope or hill, startin a lower gear rather than downshifting toa lower gear from a higher gear once theascent has started. This reduces strain onthe engine and the possibility of stalling.
If your vehicle stalls, do not try toturnaround because this could causevehicle roll over. It is better to reverse backto a safe location.
Apply just enough power to the wheels toclimb the hill. Too much power can causethe tires to slip, spin or lose traction,resulting in loss of vehicle control.
Descend a hill in the same gear you woulduse to climb up the hill to avoid excessivebrake application and brake overheating.Do not descend in neutral. Disengageoverdrive or move the transmissionselector lever to a lower gear. Whendescending a steep hill, avoid sudden hardbraking as you could lose control. The frontwheels have to be turning in order to steeryour vehicle.

COLD WEATHER
PRECAUTIONS
The functional operation of somecomponents and systems can be affectedat temperatures below approximately-13°F (-25°C).
DRIVING ON SNOW AND ICE
WARNING: If you are driving inslippery conditions that require tirechains or cables, then it is critical thatyou drive cautiously. Keep speeds down,allow for longer stopping distances andavoid aggressive steering to reduce thechances of a loss of vehicle controlwhich can lead to serious injury or death.If the rear end of your vehicle slides whilecornering, steer in the direction of theslide until you regain control of yourvehicle.
On ice and snow, you should drive moreslowly than usual. Your vehicle has a fourwheel anti-lock brake system, do not pumpthe brake pedal. See Anti-Lock BrakingSystem Limitations (page 229).
BREAKING-IN
Your vehicle requires a break-in period. Forthe first 1,000 mi (1,600 km), avoid drivingat high speeds, heavy braking, aggressiveshifting or using your vehicle to tow. Duringthis time, your vehicle may exhibit someunusual driving characteristics.
DRIVING ECONOMICALLY
The following helps to improve fuelconsumption:
•Drive smoothly, accelerate gently andanticipate the road ahead to avoidheavy braking.
•Regularly check your tire pressures andmake sure that they are inflated to thecorrect pressure.
•Follow the recommended maintenanceschedule and carry out therecommended checks.
•Plan your journey and check the trafficbefore you set off. It is more efficientto combine errands into a single tripwhenever possible.
•Avoid idling the engine in cold weatheror for extended periods. Start theengine only when you are ready to setoff.
•Do not carry unnecessary weight in yourvehicle as extra weight wastes fuel.
•Do not add unnecessary accessoriesto the exterior of your vehicle, forexample running boards. If you use aroof rack, remember to fold it down orremove it when not in use.
•Do not shift into neutral when you arebraking or when your vehicle is slowingdown.
•Shut all windows when driving at highspeeds.
•Switch off all electric systems whennot in use, for example air conditioning.Make sure that you unplug anyaccessories from the auxiliary powerpoints when not in use.

DRIVING IN SPECIAL
CONDITIONS
DRIVING THROUGH MUD ANDWATER
Mud
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud. Even all-wheel drive and four-wheeldrive vehicles can lose traction in mud. Ifyour vehicle slides, steer in the direction ofthe slide until you regain control of yourvehicle. After driving through mud, cleanoff residue stuck to rotating driveshaftsand tires. Excess residue can cause animbalance that could damage drivecomponents.
Note:If your vehicle gets stuck in mud, itcould be rocked out by shifting betweenforward and reverse gears, stoppingbetween shifts in a steady pattern. Presslightly on the accelerator in each gear.
Note:Do not rock your vehicle if the engineis not at normal operating temperature, asdamage to the transmission could occur.
Note:Do not rock your vehicle for morethan a minute, as damage to thetransmission and tires could occur or theengine could overheat.
Water
If you must drive though deep water, driveslowly. The water could limit traction orbrake capability. See Driving ThroughShallow Water (page 391).
When driving though water, determine thedepth and avoid water higher than thecenter of the wheel.
Once through water, always try the brakes.Wet brakes do not stop your vehicle asquickly as dry brakes. Apply light pressureto the brake pedal while slowly moving thevehicle to dry the brakes.
Note:Driving through deep water couldcause damage to the transmission. If thefront or rear axle is submerged in water,have the axle lubricant and power transferunit lubricant checked and changed ifnecessary.
DRIVING ON HILLY OR SLOPINGTERRAIN
WARNING: Extreme care shouldbe used when steering the vehicle inreverse down a slope so as not to causethe vehicle to swerve out of control.
Although natural obstacles could make itnecessary to travel diagonally up or downa hill or steep incline, you should try to drivestraight up or straight down.
Note:Avoid turning on steep slopes or hills.A danger lies in losing traction, slippingsideways and possible vehicle roll over.Whenever driving on a hill, determinebeforehand the route you can use. Do notdrive over the crest of a hill without seeingwhat conditions are on the other side. Donot drive in reverse over a hill without theaid of an observer.
Apply just enough power to the wheels toclimb the hill. Too much power causes thetires to slip, spin or lose traction, and youcould lose control of your vehicle. Whendescending a steep hill, do not descendthe hill in neutral. Avoid sudden hardbraking to keep the front wheels rolling andto maintain your vehicle's steering.
Note:Your vehicle has anti-lock brakes,apply the brakes steadily. Do not pump thebrakes.
