FOUR-WHEEL DRIVE
PRECAUTIONS
WARNING: Vehicles with a highercenter of gravity (utility and four-wheeldrive vehicles) handle differently thanvehicles with a lower center of gravity(passenger cars). Avoid sharp turns,excessive speed and abrupt steering inthese vehicles. Failure to drive cautiouslyincreases the risk of losing control of yourvehicle, vehicle rollover, personal injuryand death.
WARNING: Do not becomeoverconfident in the ability of four-wheeldrive vehicles. Although a four-wheeldrive vehicle may accelerate better thana two-wheel drive vehicle in low tractionsituations, it won't stop any faster thantwo-wheel drive vehicles. Always driveat a safe speed.
Truck and utility vehicles can differ fromsome other vehicles. Your vehicle could behigher to allow it to travel over roughterrain without getting stuck or damagingunderbody components. The differencesthat make your vehicle so versatile alsomake it handle differently than an ordinarypassenger car. Always maintain steeringwheel control, especially in rough terrain.Since sudden changes in terrain can resultin abrupt steering wheel motion, make sureyou grip the steering wheel from theoutside. Do not grip the spokes. Drivecautiously to avoid vehicle damage fromconcealed objects such as rocks andstumps. Drive slower in strong crosswindswhich can affect the normal steeringcharacteristics of your vehicle. Beextremely careful when driving onpavement made slippery by loose sand,water, gravel, snow or ice.
Note:Your vehicle may come with a frontair dam that can become damaged (due toreduced ground clearance) when taking yourvehicle off-road. This air dam can be takenoff by removing 15 bolts.
Parking
WARNING: If the parking brake isfully released, but the brake warninglamp remains illuminated, the brakesmay not be working properly. Have yourvehicle checked as soon as possible.
WARNING: Apply the parkingbrake, shift into park (P), switch theignition off and remove the key beforeyou leave your vehicle. Failure to followthis instruction could result in personalinjury or death.
On some four-wheel drive vehicles, whenthe transfer case is in the neutral (N)position, the engine and transmissiondisconnects from the rest of the driveline.Therefore, your vehicle is free to roll evenif the automatic transmission is in park (P).Do not leave the vehicle unattended withthe transfer case in the neutral (N)position. Always set the parking brake fullyand turn off the ignition when leaving yourvehicle.
FOUR-WHEEL DRIVE
LIMITATIONS
Do not use four-wheel drive high orfour-wheel drive low mode on dry, hardsurface roads. Doing so can produceexcessive noise, increase tire wear and candamage drive components. Four-wheeldrive high or four-wheel drive low modesare intended for consistently slippery orloose surfaces. Use of four low mode onthese surfaces could produce some noise,such as occasional clunks, but should not

WHAT IS TRACTION CONTROL
The traction control system helps to avoiddrive wheel spin and loss of traction.
HOW DOES TRACTION
CONTROL WORK
If your wheels begin to spin, the loss oftraction can compromise steering controland stability of the vehicle. The tractioncontrol system applies the brakes toindividual wheels and when needed,reduces engine power at the same time toincrease traction.
SWITCHING TRACTION
CONTROL ON AND OFF
WARNING: Operating your vehiclewith the traction control disabled couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
The traction control system turns on eachtime you switch the ignition on.
The button for the stability and tractioncontrol system is on the instrument panel.
Press and release the button to switchtraction control off. The stability controlsystem remains fully active, to switch it off,press and hold the button for a fewseconds, then release.
When you switch traction control off, amessage and an illuminated icon appearon the instrument cluster.
Press the switch again to turn the tractioncontrol system back on to normaloperation.
If your vehicle is stuck in mud or snow,switching traction control off may bebeneficial as this allows the wheels to spin.

HYDRAULIC POWER
STEERING
HYDRAULIC POWER STEERINGGUIDELINES
To help prevent damage to the powersteering system:
•Do not hold the steering wheel at itsfurthest turning points for more thanthree to five seconds when the engineis running.
•Avoid continuously steering back andforth with elevated engine RPM as thismay overheat the system. If trying tofree a stuck vehicle, pause betweenattempts to allow the power steeringsystem to cool or seek assistance.Typical steering and driving maneuversallow the system to cool.
•Do not operate the vehicle if the powersteering pump fluid level is below theMIN mark on the reservoir.
•Some noise is normal during operation.If excessive, check for low powersteering pump fluid level beforeseeking service by your dealer.
•Heavy or uneven efforts may be causedby low power steering fluid. Check forlow power steering pump fluid levelbefore seeking service by your dealer.
•Do not fill the power steering pumpreservoir above the MAX mark on thereservoir, as this may result in leaksfrom the reservoir.
If the power steering system breaks downor if you switch the engine off, you cansteer the vehicle manually, but it takesmore effort.
If you have any steering componentsserviced or replaced, install new fasteners.Many fasteners have coatings with threadadhesive, or have prevailing torquefeatures you cannot reuse. Do not reuse abolt or nut. Torque fasteners tospecifications.
Steering Tips
If the steering wanders or pulls, check for:
•An improperly inflated tire.
•Uneven tire wear.
•Loose or worn suspensioncomponents.
•Loose or worn steering components.
•Improper vehicle alignment.
Note:A high crown in the road or highcrosswinds may also make the steeringseem to wander or pull.
Electronic Torque Overlay Steering
(If Equipped)
WARNING: The electric powersteering system has diagnostic checksthat continuously monitor the system. Ifa fault is detected, a message displaysin the information display. Stop yourvehicle as soon as it is safe to do so.Switch the ignition off. After at least 10seconds, switch the ignition on andwatch the information display for asteering system warning message. If asteering system warning messagereturns, have the system checked assoon as possible.
WARNING: If the system detectsan error, you may not feel a difference inthe steering, however a serious conditionmay exist. Have your vehicle checked assoon as possible. Failure to do so mayresult in loss of steering control.

PARKING AID PRECAUTIONS
WARNING: To help avoid personalinjury, always use caution when inreverse (R) and when using the sensingsystem.
WARNING: The system may notdetect objects with surfaces that absorbreflection. Always drive with due careand attention. Failure to take care mayresult in a crash.
WARNING: Traffic control systems,fluorescent lamps, inclement weather,air brakes, external motors and fans mayaffect the correct operation of thesensing system. This may cause reducedperformance or false alerts.
WARNING: The system may notdetect small or moving objects,particularly those close to the ground.
WARNING: The parking aid systemcan only assist you to detect objectswhen your vehicle is moving at parkingspeeds. To help avoid personal injury youmust take care when using the parkingaid system.
WARNING: The system may notfunction if the sensor is blocked.
WARNING: In cold and severeweather conditions the system may notfunction. Rain, snow and spray can alllimit sensor performance.
WARNING: If damage occurs in theimmediate area surrounding the sensor,have your vehicle checked as soon aspossible.
Note:If your vehicle sustains damageleaving the sensors misaligned, this willcause inaccurate measurements or falsealerts.
When you connect a trailer to your vehicle,the rear parking aid detects the trailer andprovides an alert. Disable the parking aidwhen you connect a trailer to prevent thealert.
Note:Connected trailers might be detectedby the vehicle and parking aid turns offautomatically in those instances.
Note:Certain add-on devices installedaround the bumper or fascia may createfalse alerts, for example, large trailerhitches, bike or surfboard racks, license platebrackets, bumper covers or any other devicethat could block the normal detection zoneof the parking aid system. Aftermarket sparetires or spare tire covers mounted to the reartailgate could cause false alerts from thepark aid system. Remove the add-on deviceto prevent false alerts.
Note: Keep the sensors free from snow, iceand large accumulations of dirt. If thesensors are covered, the system's accuracycan be affected.
Do not clean the sensors with sharpobjects.
