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 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.
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 2WD 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
●
If any of the requirements to select a new transfer
case position have not been met, then the transfer
case will not shift. The position indicator light for
the previous 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, then the current
position indicator light will turn off and 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
2WD 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.
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
original 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
detrimental 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:
Preferred Procedure
1. With the engine running, slow the vehicle to 2 to 3
mph (3 to 5 km/h).
2. Shift the transmission into NEUTRAL.
3. While still rolling, push the desired position on the
transfer case control switch.
4. After the desired position indicator light is on (not
flashing), shift the transmission back into gear.
Alternate Procedure
1. Bring the vehicle to a complete stop.
2. With the ignition switch in the ON/RUN position
and the engine running, shift the transmission into
NEUTRAL.
3. Push the desired position on the transfer case
control switch.
4. After the desired position indicator light is on (not
flashing), shift the transmission back into gear.
