• Do not shift into 4H (4x4
High) with the rear wheels
slipping.
• The vehicle should not be
driven in 4X4 High with the
hub locks disengaged as this
condition may damage
driveline system components.
Shifting from 4H (4x4 High) to 2H (2WD)
Move the transfer case lever to 2H
(2WD) at a stop or a vehicle speed
below 3 mph (5 km/h).
With the vehicle at complete stop,
disengage the locking hubs
(optional) by rotating the hub lock
control from LOCK to FREE.
• For proper operation, make
sure that both indicator arrows on the hub are aligned, and
that both hubs are set to FREE.
Shifting from 2H (2WD) or 4H (4x4 High) to 4L (4x4 Low)
1. Bring the vehicle to a stop or a speed below 3 mph (5 km/h).
2. Place the transmission in N (Neutral).
3. Move the transfer case shift lever
through N (Neutral) directly to 4L
(4x4 Low).
4. If the shift lever does not, or only
partially moves to the 4L (4x4 Low)
position, perform a shift with the
transmission in N (Neutral) and the
vehicle rolling at a speed below
3 mph (5 km/h). This will ensure the transfer case is fully engaged into
4L (4x4 Low).
Note: The vehicle should not be driven in 4X4 High with the hub locks
disengaged as this condition may damage driveline system components.
