STARTING AND OPERATING
171
The system requires that the ignition be in the
ON/RUN position or the engine running for all user
requested changes. When lowering the vehicle, all
of the doors must be closed. If a door is opened at
any time while the vehicle is lowering, the change
will not be completed until the open door(s) is
closed.
This system uses a lifting and lowering pattern
which keeps the headlights from incorrectly
shining into oncoming traffic. When raising the
vehicle, the rear of the vehicle will move up first
and then the front. When lowering the vehicle, the
front will move down first and then the rear.
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.
To assist with changing a spare tire, the air
suspension system has a feature which allows the
automatic leveling to be disabled

NOTE:
Default Ride Height:
Select Aero Height or Normal Ride Height as
the default for all vehicle speeds and oper
-
ation. This is the selected height that the
suspension will level for speed changes
(e.g. raising from Entry/Exit Height at speed,
lowering from Off-Road Height at speed,
etc.).
Default ride height can be changed by
manually adjusting the Air Suspension
switch to Normal Ride Height or Aero Ride
Height and staying in the selected height for
2.5 seconds. It will be stored as the default
ride height and the height will be main
-
tained until a new default ride height is
selected.
If equipped with a touchscreen radio, all enabling/
disabling of air suspension features must be done
through the radio

Transport Mode
For towing your vehicle with four wheels off the
road, the air suspension system has a feature
which will put the vehicle into Entry/Exit height and
disable the automatic load leveling system

page 237.
Wheel Alignment Mode
Before performing a wheel alignment, this mode
must be enabled which moves the vehicle to
normal ride height and disables the automatic
leveling
Ú
page 237.
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.

volume of air to operate the system. To avoid
personal injury or damage to the system, see an
authorized dealer for service.
