Wheel Alignment Mode
Before performing a wheel alignment this mode must be
enabled. Refer to “Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument Panel” for
further information.
NOTE:This mode is intended to be enabled with engine
running.
Protection Mode
In order to “protect” the air suspension system, the vehicle
will enter Protection Mode when load leveling cannot be
achieved. Some driving may be required to clear the pro-
tection mode telltale in the EVIC. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Understanding
Your Instrument Panel” for further information.
NOTE: If equipped with a touch screen radio all
enabling/disabling of air suspension features must be
done through the radio. Refer to “Uconnect® Access Settings” in “Understanding Your Instrument Panel” for
further information.

AIR SUSPENSION SYSTEM (2500/3500 MODELS
ONLY) — 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. 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

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
5
STARTING AND OPERATING 461

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.
CAUTION!
•Do not lock the front or rear axle on hard surfaced
roads. The ability to steer the vehicle is reduced
and damage to the drivetrain may occur when the
axles are 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
drivetrain components. Lock the rear axle before
attempting situations or navigating terrain, which
could possibly cause the vehicle to become stuck. The locking axles are controlled by the axle locker switch.
The switch has three positions, AXLE UNLOCK, REAR
LOCK, and FRONT/REAR LOCK. Under normal driv-
ing conditions, the switch should be left in the AXLE
UNLOCK position. In the AXLE UNLOCK position, the
front and rear axles are unlocked. In the REAR LOCK
position, the rear axle is locked. In the FRONT/REAR
LOCK position, the front and rear axles are locked.
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.
462 STARTING AND OPERATING

To lock the rear axle, place the vehicle in 4LO. Refer to
“Four Wheel Drive Operation” in “Starting and Operat-
ing” for further information. Move the axle locker switch
position to REAR LOCK while traveling less than 3 mph
(5 km/h). The RR indicator light will remain on when the
rear axle is locked.
NOTE:
Left to right wheel speed difference may be neces-
sary to allow the axle to fully lock. If the indicator light is
flashing after placing the switch in the REAR LOCK or
FRONT/REAR LOCK position, drive the vehicle in a turn
or on loose gravel to expedite the locking action.
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.
To lock the front axle; move the axle locker switch to
FRONT/REAR LOCK while traveling less than 3 mph
(5 km/h). The indicator light will be solid when the front
axle is locked.
NOTE: The rear axle must be locked before the front axle
will lock.
To unlock the front axle; move the axle locker switch to
REAR LOCK. 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.
5
STARTING AND OPERATING 463

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.
WARNING!
Do not disconnect the stabilizer bar and drive on hard
surfaced roads or at speeds above 18 mph (29 km/h),
you may lose control of the vehicle, which could result
in serious injury or death. The front stabilizer bar
enhances vehicle stability and is necessary for main-
taining control of the vehicle. The system monitors
vehicle speed and will attempt to reconnect the stabi-
lizer bar at speeds over 18 mph (29 km/h). This is
indicated by a flashing off road light and solid on road
light. Once vehicle speed is reduced below 14 mph
(22 km/h), the system will attempt to return to the
Off-Road mode.
To disconnect the stabilizer/sway bar, shift to either 4HI
or 4LO as shown in “Four Wheel Drive Operation” and
press the right hand Off Road stabilizer/sway bar button
to obtain the Off-Road position. The amber indicator
light will flash until the stabilizer/sway bar has been
fully disconnected.
NOTE:The stabilizer/sway bar may be torque locked
due to left and right suspension height differences. This
condition is due to driving surface differences or vehicle
loading. In order for the stabilizer/sway bar to
disconnect/reconnect, the right and left halves of the bar
must be aligned. This alignment may require that the
vehicle be driven onto level ground or rocked from side
to side.
To return to the On-Road mode; press the left hand On
Road stabilizer/sway bar button.
5
STARTING AND OPERATING 465

WARNING!
If the stabilizer/sway bar will not return to On-Road
mode, vehicle stability is greatly reduced. Do not
attempt to drive the vehicle over 18 mph (29 km/h).
Driving faster than 18 mph (29 km/h) may cause loss
of control of the vehicle, which could result in
serious injury or death. Contact your local service
center for assistance.
SAFE OFF-ROAD DRIVING — POWER WAGON
ONLY
Off-Road Driving Tips And Vehicle Characteristics
Your vehicle has excellent on and off-road capabilities.
These off-road capabilities will allow you to explore
those wilderness trails where few travel, providing a
source of exciting and satisfying recreation. Before you
venture out, you should contact your local governmentalagency to determine the designated off-road vehicle
(ORV) trails or recreation areas. You should always tread
lightly and only use established roads, trails or ORV
recreational areas. The National Forest Service, Bureau of
Land Management or local Department of Natural Re-
sources are a wealth of information and usually have
maps with marked trails.
Skid Plates And Underbody Protection
Steel skid plates protect the major driveline components
of the truck including the fuel tank, transfer case and
steering damper. In addition, this vehicle is equipped
with boxed cross members and fore/aft rails. This addi-
tional protection allows the vehicle to be utilized in
severe off-road situations that would be considered im-
passable by a normal truck.
Ramp Travel Index (RTI)
The ramp travel index is the distance, in inches, that you
can drive your vehicle with one wheel on a 20-degree
