2WD To 4WD LOCK
Push the desired position on the 4WD control switch to
shift the transfercase. Shifts between 2WD and 4WD LOCK
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 selecting the desired position on the control
switch. If the vehicle is stopped, the ignition must be in the
ON 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 LOCK 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 LOCK 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. 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 complete stop.
2. With the ignition switch in the ON 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.
