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.

require any action by the driver.
AUTOMATIC TRANSMISSION OPERATION
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the ON position unless the brake pedal is depressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the ON position and the brake pedal depressed:
1. Apply the parking brake, turn ignition key to LOCK, then remove the
key.
2. Insert the key and turn it to OFF.Apply the brake pedal and shift
to N (Neutral).
When the key is in the ignition OFF position, the automatic
transmission shift lever can be moved from the P (Park) position
without the brake pedal depressed. To avoid unwanted vehicle
movement, always set the parking brake.
3. Start the vehicle.
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
emergencieschapter.
