Locking Rear Axle

If equipped, the locking rear axle can give
the vehicle additional traction from the rear
wheels when traveling in off-road situations
such as mud, snow, steep hills, and uneven
terrain.
Caution
If you try to lock the axle while the
vehicle is stuck and the tires are spinning,
the vehicle s drivetrain could be damaged.
The repairs would not be covered by the
vehicle warranty. Always lock the axle
before attempting situations and/or
navigating terrain that could cause the
vehicle to become stuck.
Caution
If the vehicle s axle is locked while driving
on pavement, the drivetrain could be
damaged. Repairs would not be covered
by the vehicle warranty. Do not use the
locking axle on pavement.
Before the front axle can be locked, the rear
axle must be locked and the transfer case
must be in 4 .
To lock the rear axle:
1. Press the rear axle locking switch with
the vehicle moving less than 30 km/h
(20 mph).
2. Wait for the light in the switch to stop
flashing and remain illuminated to show
that the rear axle is locked.
If the electronic locking differential has
difficulty engaging, release the
accelerator pedal.
The locking rear axle will be disengaged
when the vehicle speed exceeds 30 km/h
(20 mph). The Off-Road Mode allows the
axle lock to remain engaged at higher
vehicle speeds.
Driving and Operating
After pressing the switch to unlock the axle,
it may remain locked due to torque in the
driveline. The axle is more easily unlocked
by turning the steering wheel to the right
and to the left while traveling at a low
speed.

Locking Front Axle

If equipped, the locking front axle can give
the vehicle additional traction when
traveling in off-road situations such as mud,
snow, steep hills, and uneven terrain.
The locking front axle must not be used on
high traction surfaces such as pavement.
