Protection Strategy
In order to “protect” the air suspension system, the

(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

OPERATION
Air Suspension Switch
The indicator lamps 1 through 4 will illuminate to
show
the current position of the vehicle. Flashing
indicator lamps will show a position which the
system is working to achieve. When raising or
lowering, the flashing indicator lamp is the position
the system is working to achieve.
Pushing the height selector switch up once will
move
the suspension one position higher from the
current position, assuming all conditions are met
(i.e., key in ON/RUN position, engine running,
speed below threshold, etc.). The height selector
switch can be pushed up multiple times, each push
will raise the requested level by one position up to
a maximum position of OR or the highest position
allowed based on current conditions (i.e., vehicle
speed, etc.).
Pushing the height selector switch down once will
move
the suspension one position lower from the
current level, assuming all conditions are met (i.e.,
key in ON/RUN position, engine running, doors
closed, speed below threshold, etc.). The height
selector switch can be pushed down multiple
times, each push will lower the requested level by
one position down to a minimum of Entry/Exit
Mode or the lowest position allowed based on
current conditions (i.e., vehicle speed, etc.).
