162 STARTING AND OPERATING
AXLE Lock Selector
The locking axles are controlled by the axle lock
buttons.
Under normal driving conditions, the vehicle
should be left in the AXLE UNLOCK position.
NOTE:
Even when the axles are in the AXLE UNLOCK
position, the limited slip differential in the rear
axle still provides torque biasing capability for
moderate low traction environments.
During the command to lock the axle, the indicator
light will flash until the axle is locked. After the lock
command has been successfully executed, the
light will remain on solid.
To lock the rear axle, place the vehicle in 4WD
LOW, 4WD HIGH or two-wheel drive Ú page 152.
Push the REAR LOCK button while traveling less
than 10 mph (16 km/h). The REAR LOCK indicator
light will remain on when the rear axle is locked.
NOTE:
Left to right wheel speed difference may be
necessary to allow the axle to fully lock. If the indi-
cator light is flashing after placing the vehicle in
the REAR LOCK or FRONT/REAR LOCK position,
drive the vehicle in a turn or on loose gravel to
expedite the locking action.
To lock the front axle, push the FRONT/REAR LOCK
button while traveling less than 10 mph (16 km/h)
in 4WD LOW. The FRONT/REAR LOCK indicator
light will be solid when the front axle is locked.
NOTE:
The rear axle must be locked before the front axle
will lock.
When both the axles are locked, to unlock the front
axle, push the REAR LOCK button while in 4WD
LOW. The FRONT/REAR LOCK indicator light will go
out when the axle is unlocked.
NOTE:
The axle lockers could be torque locked due to side
to side loads on the axle. Driving slowly while
turning the steering wheel from a left hand turn to
a right hand turn or driving in REVERSE for a short
distance may be required to release the torque
lock and unlock the axles.
To unlock the rear axle, push the AXLE UNLOCK
button. The REAR LOCK indicator light will go out
when the rear axle is unlocked.
1 — FRONT/REAR LOCK the front and rear axles
are locked
2 — REAR LOCK – the rear axle is locked
3 — AXLE UNLOCK – the front and rear axles are
unlocked
CAUTION!
Do not lock the front or rear axle on hard
surfaced roads. The ability to steer the vehicle
is reduced and damage to the drivetrain may
occur when the axles are locked on hard
surfaced roads.
Do not try to lock the rear axle if the vehicle is
stuck and the tires are spinning. You can damage
drivetrain components. Lock the rear axle before
attempting situations or navigating terrain, which
could possibly cause the vehicle to become stuck.
WARNING!
Do not use the locked axle position for normal
driving. A locked front axle is intended for off-road
driving only. Locking the front axle during on-road
driving will reduce the steering ability. This could
cause a collision and you may be seriously injured.
