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 Quadra-Lift™ air
suspension system has a feature which allows the auto-
matic leveling to be disabled. Press and hold both the
“Up” and “Down” buttons simultaneously between 5
and 10 seconds, a message will appear in the EVIC
stating leveling has been disabled immediately after both
buttons have been released. Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information. Driving the
vehicle over 5 mph (8 km/h) will return the air suspen-
sion to normal operation. Refer to “Jacking and Tire
Changing” in “What To Do In Emergencies” for further
information.WARNING!
The air suspension system uses a high pressure
volume of air to operate the system. To avoid per-
sonal injury or damage to the system, see your
authorized dealer for service.
