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, as this can 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 previous posi -
tion 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. To retry
a shift: return the control switch back to the original
position, make certain all shift requirements have been
met, wait five seconds and try the shift again.

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 position 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 engine either running or off.
This shift cannot be completed if the ignition switch is in
the ACC position.
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.
