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

3.Reinsert the lug wrench extension(s)through the rear bumper and guidetube and turn the lug wrench clockwiseuntil the tire is raised to its stowedposition underneath the vehicle. Thewrench will become harder to turn andthe spare tire winch will ratchet or slipwhen the tire is raised to maximumtightness. You will hear a clicking soundfrom the winch indicating that the tireis properly stowed, tighten until aminimum of three clicks are heard.Check that the tire lies flat against theframe and is secure.
4.Carefully place all tools back in the toolkit bag.
5.Reinstall the tool kit bag and tightenthe wing nut.
6.Properly reinstall the jack into thebracket and tighten the wing nut.
WHEEL NUTS
WARNING: When you install awheel, always remove any corrosion, dirtor foreign materials present on themounting surfaces of the wheel or thesurface of the wheel hub, brake drum orbrake disc that contacts the wheel. Makesure to secure any fasteners that attachthe rotor to the hub so they do notinterfere with the mounting surfaces ofthe wheel. Installing wheels withoutcorrect metal-to-metal contact at thewheel mounting surfaces can cause thewheel nuts to loosen and the wheel tocome off while your vehicle is in motion,resulting in loss of vehicle control,personal injury or death.

1 Torque specifications are for nut and boltthreads free of dirt and rust. Use only ourrecommended replacement wheel nutsand or wheel bolts.
Retighten the wheel nuts to the specifiedtorque within 100 mi (160 km) after anywheel disturbance, such as tire rotation,changing a flat tire or wheel removal.
On vehicles equipped with dual rearwheels, retighten the wheel lug nuts to thespecified torque at 100 mi (160 km), andagain at 500 mi (800 km) of new vehicleoperation and after any wheel disturbance,such as tire rotation, changing a flat tire,or wheel removal.
It is important to follow the proper wheelmounting and lug nut torque procedures.
