154 STARTING AND OPERATING
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
selection. 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
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. To find the shift
requirements Ú page 154.
The SERV 4WD Warning Light monitors the
electronic shift 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.
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 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 position
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 posi-
tion will stop flashing and remain on.
2WD TO 4WD HIGH
Push the desired position on the four-wheel drive
control 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
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.
