168 STARTING AND OPERATING
Wheel Alignment Mode
Before performing a wheel alignment, this
mode must be enabled 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.
NOTE:
For towing with air suspension Ú page 214.
INSTRUMENT CLUSTER DISPLAY
M
ESSAGES
When the appropriate conditions exist, a
message will appear in the instrument cluster
display Ú page 114.
An audible chime will be heard whenever a
system error has been detected.
See an authorized dealer for system service if
normal operation does not resume.
OPERATION
Air Suspension Switch
The indicator lamps 1 through 5 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, if multiple indicator lamps are flashing,
the highest flashing indicator lamp is the
position the system is working to achieve. When
lowering, if multiple indicators are flashing, the
lowest solid indicator lamp is the position the
system is working to achieve.
Pushing the height selector 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 OR2 or the highest
position allowed based on current conditions
(i.e. vehicle speed, etc).
Pushing the height selector 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.)
Automatic height changes will occur based on
vehicle speed and the current vehicle height.
The indicator lamps and instrument cluster
display messages will operate the same for
automatic changes and user requested
changes.
