To Know Your Instrument Panel” or “Uconnect Settings” in

loaded, battery charge low, etc.). Load leveling will automat -
ically resume as soon as system operation requirements are
met. See your authorized dealer if system does not resume.

If towing with air suspension refer to “Trailer Towing” in
“Starting And Operating” for further information.

ment Cluster Display” in “Getting To Know Your Instru-
ment Panel” for further information. An audible chime will be heard whenever a system error has

The indicator lamps 1 through 4 will illuminate to show the

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

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 -

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.)

and the current vehicle height. The indicator lamps and instrument cluster display messages will operate the same
for automatic changes and user requested changes.
