Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD and
4WD LOW) are located in the instrument cluster and
indicate the current and desired transfer case selec-
tion. When you select a different transfer case position,
the indicator lights will do the following:
If All Of The Following Shift Conditions Are Met:
1. The current position indicator light will turn off.
2. The selected position indicator light will flash until
the transfer case completes the shift.
3. When the shift is complete, the indicator light for the
selected position will stop flashing and remain on.
If One Or More Of The Following Shift Conditions Are
Not Met:
1. The indicator light for the current position will
remain on.
2. The newly selected position indicator light will con-
tinue 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 electroni-
cally shifted four-wheel drive system. 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.
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.
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 two-
wheel drive or 4WD HIGH 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 indicator light for the pre-
vious position will remain on and the newly selected
position indicator light will continue to flash until all
the requirements for the selected position have
been met.
•
If all the requirements to select a new transfer case
position have been met, the current position indica-
tor 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 indi-
cator light for the selected position will stop flashing
and remain on.
2WD TO 4WD HIGH
Push the desired position on the four-wheel drive con-
trol switch to shift the transfer case. Shifts between
two-wheel drive and 4WD HIGH can be done with the
vehicle stopped or in motion. With the vehicle in
motion, the transfer case will engage/disengage faster
if you momentarily release the accelerator pedal after
turning the control switch. If the vehicle is stopped, the
ignition switch must be in the ON/RUN position with the
engine either running or off. This shift cannot be com-
pleted if the ignition switch is in the ACC position.
NOTE:
The four-wheel drive system will not allow shifts
between 2WD/4WD HIGH if the front and/or rear
wheels are spinning (no traction). In this situation, the
selected position indicator light will flash and the origi-
nal position indicator light will remain on. At this time,
reduce speed and stop spinning the wheels to complete
the shift.
2WD OR 4WD HIGH TO 4WD LOW
NOTE:
When shifting into or out of 4WD LOW some gear noise
may be heard. This noise is normal and is not detrimen-
tal to the vehicle or occupants.
Shifting can be performed with the vehicle rolling 2 to
3 mph (3 to 5 km/h) or completely stopped. You can
use either of the following procedures:
