N (Neutral)
Only used when towing the vehicle. No
power to front or rear wheels.
4L (4X4 Low)
Uses extra gearing to provide maximum
power to all four wheels at reduced
speeds. Intended only for off road
applications such as deep sand, steep
grades or pulling heavy objects.
Shifting between system modes
Note: Do not perform these operations if
the rear wheels are slipping or when
applying the accelerator pedal.
Note: Some noise may be heard as the 4x4
system shifts or engages. This is normal. In
order to reduce engagement noise, it is
recommended that all shifts be performed
at speeds below3 mph (5 km/h).
Note: The vehicle should not be driven in
4X4 High with the hub locks disengaged as
this condition may damage driveline system
components.
Engage the locking hubs by rotating the
hub lock control from FREE to LOCK, then
move the transfer case lever from 2H to
4H at a stop or a vehicle speed below
3 mph (5 km/h).
Move the transfer case lever from 4H to
2H at a stop or a vehicle speed below
3 mph (5 km/h), then disengage the
locking hubs (optional) by rotating the hub
lock control from LOCK to FREE.
For proper operation, make sure that both
hubs are set to either FREE or LOCK.
Shifting to or from 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 the
desired position.
4. If the transfer case does not, or only
partially moves to the desired position,
perform a shift with the transmission
in N (Neutral) and the vehicle rolling at
a speed below 3 mph (5 km/h).
5. If shifting to 2H with the vehicle at a
complete stop, disengage the locking
hubs (optional) by rotating the hub
lock control from LOCK to FREE.
Using the N (Neutral) position
WARNING: Always set the parking
brake and leave your vehicle with the
transmission in park (P).
E233846
The transfer case neutral position overrides
the transmission and puts the vehicle in
neutral regardless of transmission gearshift
lever position. The vehicle can move
forward or backwards.
This position should only be used when
towing the vehicle.
