HOW DOES FOUR-WHEEL
DRIVE WORK
Using the Electronic Shift On theFly System (If Equipped)
This four-wheel drive system utilizes a2-speed Electronic Shift On the Fly (ESOF)transfer case which is also known as apart-time system. This system offers thedriver two-wheel drive high, four-wheeldrive high, and four-wheel drive low asavailable modes of operation. When youselect either four-wheel drive high orfour-wheel drive low, the system providesmechanically locked four-wheel drivepower to both the front and rear wheelsfor use in off-road or slippery conditionssuch as deep snow, sand or mud. Whenyou select four-wheel drive low, the systemprovides additional gearing for increasedtorque multiplication for conditions likedeep sand, steep slopes, or pulling heavyobjects. Additionally, the system is capableof recreational flat towing by putting thetransfer case into a neutral position. SeeRecreationally Towing Your Vehicle(page 427).
There is further information available ondriving in unique driving conditions. SeeOff-Road Driving (page 412).
Your vehicle has manual hub locks on thedriver side and passenger side of yourvehicle. For proper operation, make surethat each hub is fully engaged and thatboth hub locks are set to the same position(both set to lock or both set to auto). Toengage lock, turn the hub locks completelyclockwise. To engage auto, turn the hublocks completely counterclockwise.
The ESOF four-wheel drive system:
•Provides 4x4 High engagement anddisengagement while the vehicle ismoving.
•Operates by a push button controllocated on the instrument panel thatallows you select 4x2, 4x4 High or 4x4Low operation.
•Uses auto-manual hub locks. When setto auto, the hubs engage anddisengage automatically based on the4x4 mode you select. When set to lock,the hubs remain engaged at all times.
•Increases fuel economy when used inthe hub lock's recommended automode.
Note:Auto-manual hub locks manuallylock by rotating the hub lock control fromauto to lock.
Note:Hub locks should be in auto modewhen in 4x2 mode. If hub locks are in lockmode in 4x2 mode, there will be additionalnoise from the front axle.

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
