258 STARTING AND OPERATING
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 2WD. Refer to “Four Wheel
Drive Operation” in “Starting And Operating” for
further information. 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
indicator 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.
STABILIZER/SWAY BAR SYSTEM — POWER
WAGON ONLY
Your vehicle is equipped with an electronic
disconnecting stabilizer/sway bar. This system
allows greater front suspension travel in
off-road situations.
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.
CAUTION! (Continued)
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.
