This system keeps the rear of your vehicle at a constant level by
automatically adding air or releasing air from the springs.
If you exceed the load limit, the rear air suspension may not operate.
The air suspension shut-off switch is
located on the left side of the trunk.
If this switch is in the OFF position,
the rear air suspension will not
operate.
On vehicles equipped with
Air Suspension, turn OFF
the Air Suspension switch prior to
jacking, hoisting or towing your
vehicle.
Normal vehicle operation does not
require any action by the driver.

(Park) position without the brake pedal depressed. To avoid unwanted
vehicle movement, always set the parking brake.

If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle’s brakelamps are not
operating properly. Refer toFuses and relaysin theRoadside
