256 STARTING AND OPERATING
AIR SUSPENSION MODES
The air suspension system has multiple modes
to protect the system in unique situations:
Tire/Jack Mode
To assist with changing a tire, the air
suspension system has a feature which allows
the automatic leveling to be disabled. This
mode is intended to be enabled with the engine
running. Refer to “Instrument Cluster Display”
in “Getting To Know Your Instrument Panel” or
“Uconnect Settings” in “Multimedia” (if
equipped with a touch screen radio) for further
information.
NOTE:
This mode is intended to be enabled with the
engine running.
Transport Mode
For towing your vehicle with four wheels off the
road, the air suspension system has a feature
which will put the vehicle below Normal Ride
Height (NRH) and disable the automatic load
leveling system. This mode is intended to be
enabled with engine running. Refer to
“Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” or “Uconnect
Settings” in “Understanding Your Instrument
Panel” if equipped with a touch screen radio for
further information.
NOTE:
This mode is intended to be enabled with the
engine running.
Wheel Alignment Mode
Before performing a wheel alignment this mode
must be enabled. Refer to “Instrument Cluster
Display” in “Getting To Know Your Instrument
Panel” or “Uconnect Settings” in “Multimedia”
(if equipped with a touch screen radio) for
further information.
NOTE:
This mode is intended to be enabled with the
engine running.
Bed Lowering Mode
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. Refer to “Instrument Cluster
Display” in “Getting To Know Your Instrument
Panel” or “Uconnect Settings” in
“Understanding Your Instrument Panel” if
equipped with a touch screen radio for further
information.
Protection Strategy
In order to “protect” the air suspension system,
the vehicle will disable load leveling as required
(suspension overloaded, battery charge low,
etc.). Load leveling will automatically resume as
soon as system operation requirements are
met. See an authorized dealer if system does
not resume.

ESSAGES
When the appropriate conditions exist, a
message will appear in the instrument cluster
display. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
further information.
WARNING!
The air suspension system uses a high
pressure volume of air to operate the system.
To avoid personal injury or damage to the
system, see an authorized dealer for service.
