HOW DOES FOUR-WHEEL DRIVE
WORK
Using the 1-Speed Automatic Four-Wheel Drive System
The 1-speed automatic four-wheel drivesystem utilizes an electronically controlledon-demand 1-speed transfer case. Thissystem monitors various vehicle sensoryinputs to provide an increased level ofperformance. This system offers the drivertwo-wheel drive high, four-wheel drive autoand four-wheel drive high as available modesof operation via the selectable drive modeswitch. When four-wheel drive auto isselected, the system continuously variespower to the front wheels for optimumperformance for all on-road conditions. Whenfour-wheel drive high is selected, the systemprovides power to the front and rear wheelsfor use in off-road or slippery conditions suchas deep snow, sand or mud. There is furtherinformation on driving in unique drivingconditions. See Driving Hints (page 384).
Using the 2-Speed Automatic Four-Wheel Drive System (If Equipped)
The 2-speed automatic four-wheel drivesystem utilizes an electronically controlledon-demand 2-speed transfer case. Thissystem monitors various vehicle sensoryinputs to provide an increased level ofperformance. This system offers the drivertwo-wheel drive high, four-wheel drive auto,four-wheel drive high, and four-wheel drivelow as available modes of operation. Whenfour-wheel drive auto is selected, the systemcontinuously varies power to the front wheelsfor optimum performance for all on-roadconditions. When either four-wheel drive highor four-wheel drive low are selected with theappropriate drive modes , the four-wheeldrive system provides electronically lockedpower to the front and rear wheels for usein off-road or slippery conditions such asdeep snow, sand or mud. Selecting slowclimb also provides additional gearing forincreased torque multiplication for conditionslike deep sand, snow, steep slopes, or pulling
heavy objects. See Slow Climb (page 297).Additionally, the system is capable ofrecreational flat towing by putting thetransfer case into neutral (N). SeeRecreationally Towing Your Vehicle (page397).

WHAT IS THE ELECTRONIC
LIMITED-SLIP DIFFERENTIAL
The electronic limited-slip differential systemdirects torque across the axle, enabling thevehicle to drive over terrain and roadconditions that a conventional axle cannot.The system is active at all times and requiresno input from the driver.
Note:If your vehicle is not at optimaloperating conditions or a system fault ispresent, a warning may display in theinstrument cluster. Depending on thewarning, you may need to service yourvehicle.
Operating the Electronic Limited-SlipDifferential with a Spare or MismatchedTires
If your vehicle has an electronic limited-slipdifferential, do not use a spare tire of adifferent size than the tire provided. If youhave a spare tire installed, a message mayappear indicating the system has disabledautomatically or reduced function to preventsystem overheat and damage. Werecommend you reinstall the repaired orreplaced spare tire as soon as possible.When you replace the spare tire, the systemresumes normal operation on the next keycycle.
Trailer Towing
The electronic limited-slip differentialenhances vehicle stability during trailer towoperation. During high demand traileringevents, such as steep slopes, high speedsor with a spare tire, the system may providea warning in the instrument cluster andreduce function or enter a temporarilydisabled state. To resume normal function,stop the vehicle in a safe location and allowthe unit to adequately cool. Once the systemreaches normal operating temperatures,system function restores and the electroniclimited-slip differential restored messagedisplays.
