152 STARTING AND OPERATING
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

Default Ride Height:

Select Aero Height or Normal Ride Height as the
default for all vehicle speeds and operation.
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 ride height switch to Normal Ride
Height or Aero Ride Height and stay in the
selected height for 2.5 seconds. It will be stored
as the default ride height and the height will be
maintained 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
