STARTING AND OPERATING
Pushing the height selector switch up once will move the
suspension one position higher from the current position,
assuming all conditions are met (i.e. key in ON/RUN
position, engine running, speed below threshold, etc). The
height selector switch can be pushed up multiple times,
each push will raise the requested level by one position up
to a maximum position of OR or the highest position
allowed based on current conditions (i.e. vehicle speed,
etc).
Pushing the height selector switch down once will move
the suspension one position lower from the current level,
assuming all conditions are met (i.e. key in ON/RUN
position, engine running, doors closed, speed below
threshold, etc). The height selector switch can be pushed
down multiple times, each push will lower the requested
level by one position down to a minimum of Entry/Exit
Mode or the lowest position allowed based on current
conditions (i.e. vehicle speed, etc.)
Automatic height changes will occur based on vehicle
speed and the current vehicle height. The indicator lamps
and instrument cluster display messages will operate the
same for automatic changes and user requested changes.

AXLE LOCKER SYSTEM — IF EQUIPPED
This vehicle is equipped with an electronically locking rear
differential. This differential, when engaged, mechanically
lock together the axle shafts forcing the wheels to spin at
an equal rate. The locking of the rear differential should
only be engaged during low-speed, extreme off-road
situations where one wheel is likely to not be in contact
with the ground. It is not recommended to drive the vehicle
with the differentials locked on pavement due to the
reduced ability to turn and speed limitations.
Axle Lock Button
CAUTION!
 Do not lock the rear axle on hard surfaced roads. The
ability to steer the vehicle is reduced and damage to
the drivetrain may occur when the axle is 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 drive-
train components. Lock the rear axle before
attempting situations or navigating terrain, which
could possibly cause the vehicle to become stuck.
The locking rear axle is controlled by the AXLE LOCKER
button.
Under normal driving conditions, the rear axle should be
unlocked.
