Shifting Procedures
4WD HI To 4WD LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the ignition switch in the
ON/RUN position or the engine running, shift the transmission into NEUTRAL and
press the “4WD LOW” button once on the transfer case switch. The “4WD LOW”
indicator light in the instrument cluster will begin to flash and remain on solid when
the shift is complete.
4WD LOW To 4WD HI
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the ignition switch in the
ON/RUN position or the engine running, shift the transmission into NEUTRAL, and
press the “4WD LOW” button once on the transfer case switch. The “4WD LOW”
indicator light in the instrument cluster will flash and turn off when the shift is
complete.
NOTE:
Shifting into or out of 4WD LOW is possible with the vehicle completely stopped;
however, difficulty may occur due to the mating clutch teeth not being properly
aligned. Several attempts may be required for clutch teeth alignment and shift
completion to occur. The preferred method is with the vehicle rolling 0 to 3 mph
(0 to 5 km/h). If the vehicle is moving faster than 3 mph (5 km/h), the transfer case
will not allow the shift.
NEUTRAL Shift Procedure
WARNING!
You or others could be injured or killed if you leave the vehicle unattended with the
transfer case in the NEUTRAL (N) position without first fully engaging the parking
brake. The transfer case NEUTRAL (N) position disengages both the front and rear
driveshafts from the powertrain and will allow the vehicle to roll, even if the
transmission is in PARK. The parking brake should always be applied when the
driver is not in the vehicle.
1. Bring the vehicle to a complete stop, with the engine running.
2. Press and hold the brake pedal.
3. Shift the transmission into NEUTRAL.
