120 STARTING AND OPERATING
If the transfer case does not shift into the desired
position, one or more of the following events may
occur:
1. The indicator light for the current position will
remain on.
2. The newly selected position indicator light will
continue to flash.
3. The transfer case will not shift.
NOTE:
Before retrying a selection, make certain that all
the necessary requirements for selecting a new
transfer case position have been met. To retry the
selection, push the current position, wait five
seconds, and retry selection.
The SERV 4WD Warning Light monitors the
electronically-shifted transfer case. If this light
remains on after engine start-up or illuminates
during driving, it means that the four-wheel drive
system is not functioning properly and that service
is required.
NOTE:
Do not attempt to make a shift while only the front
or rear wheels are spinning. This could cause
damage to driveline components.
When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that of
the 2WD or 4WD LOCK positions at a given road
speed. Take care not to overspeed the engine and
do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type and
circumference on each wheel. Any difference in
tire size can cause damage to the drivetrain.
Because four-wheel drive provides improved
traction, there is a tendency to exceed safe turning
and stopping speeds. Do not go faster than road
conditions permit.
Shifting Procedure
NOTE:

If any of the requirements to select a new
transfer case position have not been met, the
transfer case will not shift. The position indi -
cator light for the previous position will remain
on and the newly selected position indicator
light will continue to flash until all the require -
ments for the selected position have been met.

If all the requirements to select a new transfer
case position have been met, the current posi -
tion indicator light will turn off, the selected
position indicator light will flash until the
transfer case completes the shift. When the
shift is complete, the position indicator light for
the selected position will stop flashing and
remain on.
LIMITED-SLIP DIFFERENTIAL
The limited-slip differential provides additional
traction on snow, ice, mud, sand and gravel,
particularly when there is a difference between the
traction characteristics of the surface under the
right and left rear wheels. During normal driving
and cornering, the limited-slip unit performs
similarly to a conventional differential. On slippery
surfaces, however, the differential delivers more of
the driving effort to the rear wheel having the
better traction.
The limited-slip differential is especially helpful
during slippery driving conditions. With both rear
wheels on a slippery surface, a slight application of
the accelerator will supply maximum traction.
When starting with only one rear wheel on an
excessively slippery surface, slight momentary
application of the parking brake may be necessary
to gain maximum traction.
WARNING!
Always engage the parking brake when powering
down the vehicle if the SERV 4WD Warning Light
is illuminated. Not engaging the parking brake
may allow the vehicle to roll which may cause
personal injury or death.
