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

FOUR-WHEEL DRIVE MODES
TWO-WHEEL DRIVE HIGH
Two-wheel drive high is for generalon-road driving. Power is sent to the rearwheels only.
Note:Two-wheel drive high can turn on oroff based on Drive Mode selection See DriveMode Control (page 311).
FOUR-WHEEL DRIVE HIGH
Four-wheel drive high provideselectronically or mechanically lockedfour-wheel drive power to both the frontand rear wheels for use in off-road orwinter conditions such as deep snow, sandor mud. This mode is not for use on drypavement.
Note:Four-wheel drive high can turn on oroff automatically based on Drive Modeselection. See Selecting a Drive Mode(page 311).
FOUR-WHEEL DRIVE LOW
Four-wheel drive low provideselectronically or mechanically lockedfour-wheel drive power to both the frontand rear wheels for use on low tractionsurfaces, but does so with additionalgearing for increased torque multiplication.This mode is only for off-road conditionssuch as deep sand, steep slopes, or pullingheavy objects.
Note:Four-wheel drive low can turn on oroff automatically based on drive modeselection. See Selecting a Drive Mode(page 311).

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.
