330 STARTING AND OPERATING
2WD to 4WD Auto
Move the transfer case switch to the desired position.
Shifts between 2WD and 4WD Auto can be done with the
vehicle stopped or in motion. If the vehicle is stopped,
the ignition switch must be in the ON position with the
engine either OFF or RUNNING. This shift cannot be
completed if the ignition switch is in the ACC position.
2WD or 4WD Auto to 4WD Low
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 its occupants.
Shifting can be performed with the vehicle rolling 2 to
3 mph (3 to 5 km/h) using the "Preferred Procedure" or
completely stopped using the "Alternate Procedure."
Preferred Procedure
1. With the engine RUNNING, slow the vehicle speed to
2 to 3 mph (3 to 5 km/h).
2. Shift the transmission into NEUTRAL.
3. While still rolling, move the transfer case switch to the
desired position.
4. After the desired position indicator light is on (not
flashing), shift the transmission into gear.
Alternate Procedure
1. Bring the vehicle to a complete stop.
2. With the ignition switch in the ON position and the
engine OFF or RUNNING, shift the transmission into
NEUTRAL.
3. Move the transfer case switch to the desired position.
4. After the desired position indicator light is on (not
flashing), shift the transmission into gear.
NOTE: Steps 1 and 2 in the "Preferred Procedure" and
the "Alternate Procedure" are requirements for shifting
