330 STARTING AND OPERATING
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 posi-
tion, 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 posi -
tion, 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 posi -
tion 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.
