STARTING AND OPERATING
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 posi
-
tion indicator light will turn off, the selected posi
-
tion 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.
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.
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.
