NOTE:
This mode is intended to be enabled with the engine
running.
Bed Lowering Mode
While at zero vehicle speed, this setting is used to lower
the rear suspension to the lowest possible height and
disable the air suspension system. It enables easier
loading/unloading of the truck and makes it easier to
hook up trailers
page 85 or page 174.
Protection Strategy
In order to protect the air suspension system, the
vehicle will disable load leveling as required (suspen-
sion overloaded, battery charge low, etc.). Load leveling
will automatically resume as soon as system operation
requirements are met. See an authorized dealer if sys-
tem does not resume.
INSTRUMENT CLUSTER DISPLAY
MESSAGES
When the appropriate conditions exist, a message will
appear in the instrument cluster display
page 85.

has been detected.
See an authorized dealer for system service if normal
operation does not resume.

AXLE LOCKER SYSTEM —IF EQUIPPED
This vehicle is equipped with an electronically locking
rear differential. Power Wagon also includes a locking
front differential. These differentials, when engaged,
mechanically lock together the axle shafts forcing the
wheels to spin at an equal rate. This allows the vehicle
to maintain its momentum and prevents it from becom-
ing stuck. The locking differentials, rear or front, 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 one or both of the differentials locked on
pavement due to the reduced ability to turn and speed
limitations.
AXLE Lock Selector
1 — FRONT/REAR LOCK – the front and rear axles are
locked (Power Wagon Only)
2 — REAR LOCK – the rear axle is locked
3 — AXLE UNLOCK – the front and rear axles are
unlocked (Rear only if equipped)
