446 STARTING AND OPERATING

Normal Ride Height (NRH)– This is the standard position
of the suspension and is meant for normal driving. It will
automatically adjust to maintain the rear ride height as
conditions change.
Alternate Trailer Height (ATH) – Lowers the vehicle
approximately 1 in (25 mm) for a level truck, to be used as
required while trailer towing. It will automatically adjust
to maintain the rear ride height as conditions change.
Trailer Decoupling/Unloading - The air suspension sys-
tem will load level (lower/exhaust only) for up to 10 min-
utes after the vehicle is turned off. This allows for easy
removal of a trailer and/or load from the back of the truck
by maintaining the ride height. After 10 minutes you will
need to turn the ignition to the run position for the air
suspension to maintain ride height. If the air suspension
system is disabled using the settings menu (Tire Jack Mode,
Transport Mode or Alignment Mode) the system will
remain disabled when the vehicle is turned off. Reactivat-
ing the air suspension can be accomplished via the settings
menu or driving the vehicle above 5 mph (8 km/h) for Tire
Jack Mode or Alignment Mode and 16 mph (26 km/h) for
Transport Mode. NOTE:
•
Most 3500 models will not lower to Alternate Trailer
Height (ATH) when unloaded.
• Refer to “Trailer Towing” in “Starting And Operating”
for further information.
Ignition OFF Behavior
For a predetermined amount of time after the ignition is off
the air suspension may adjust to maintain a proper appear-
ance.
WARNING!
The air suspension system uses a high pressure vol-
ume of air to operate the system. To avoid personal
injury or damage to the system, see your authorized
dealer for service.

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 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.
5
STARTING AND OPERATING 453

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 possi-
bly cause the vehicle to become stuck. The locking axles are controlled by the axle locker switch.
The switch has three positions:
•
AXLE UNLOCK – the front and rear axles are unlocked
• REAR LOCK – the rear axle is locked
• FRONT/REAR LOCK – the front and rear axles are
locked
Under normal driving conditions, the switch should be left
in the AXLE UNLOCK position.
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 trac-
tion 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.
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

454 STARTING AND OPERATING

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.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 assists in maintaining
control of the vehicle. The system monitors vehicle
speed and will attempt to reconnect the stabilizer 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 push
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.
