AIR SUSPENSION SYSTEM (2500/3500 MODELS) —
IF EQUIPPED
Description
The air suspension system is a rear leveling ride height
system. The main purpose of this system is to maintain
the truck’s rear ride height level.
524 STARTING AND OPERATING

Normal Ride Height (NRH)– This is the standard
position of the suspension and is meant for normal
driving.
Trailer Mode (Lowers the vehicle approximately 1 in
(25 mm)– This position will lower the rear suspension
and provide load leveling for all loading conditions
including towing a trailer. After the “ALT TRAILER
HEIGHT” button has been pushed, it will blink continu-
ously until the trailer height has been achieved.
The system requires that the ignition be in ON/RUN
position or the engine running with zero vehicle speed
for all user requested changes.
After the engine is turned off, it may be noticed that the
air suspension system operates briefly, this is normal. The
system is correcting the position of the vehicle to ensure
a proper appearance.
NOTE:If equipped with a touch screen radio all
enabling/disabling of air suspension features must be
done through the radio. Refer to “Uconnect® Settings” in
“Understanding Your Instrument Panel” for further in-
formation.

AXLE LOCKER SYSTEM — POWER WAGON
MODELS ONLY (IF EQUIPPED)
This vehicle is equipped with electronically locking front
and rear differentials. 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 becoming
stuck. The locking front and rear differentials should only
be engaged during low-speed, extreme off-road situa-
tions 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.
528 STARTING AND OPERATING

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.
Due to the use of taller springs, this vehicle has an
increased ride height of approximately 1.9 in (48.3 mm)
in the front and 1.5 in (38.1 mm) in the rear. A major
advantage to increasing ride height is the positive effect
it has on approach/departure and break over angles.
This system is controlled by the electronic control sway
bar switch located on the instrument panel.
The switch has two positions; On-Road and Off-Road. The
system is normally in the On-Road mode, indicated by a
solid green light. The stabilizer/sway bar should remain in
the On-Road mode during normal driving conditions.
