AIR SUSPENSION SYSTEM (IF EQUIPPED)
The load leveling feature of the air suspension automatically keeps the
vehicle at a constant level if a load is added or removed from the vehicle.
This system maintains the vehicle height at a constant level by
automatically adding air or releasing air from the springs to offset
changes in vehicle loads.
When ever a door is opened (including the liftgate) the system
memorizes and maintains the height of the vehicle until all doors are
closed.
It is normal to hear a buzz or clicking from the air compressor on the
vehicle when the ignition is turned off. The system stays energized for 40
minutes after the ignition is turned off to compensate for any load
changes made after the vehicle is parked.
The air suspension shut-off switch is
located in the cargo area behind the
left rear quarter trim panel.
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.

Removing the spare tire
1. Insert the jack handle into the
rear bumper opening.
The handle will stop moving and
forward resistance to turning will be
felt when properly engaged.
2. Turn the handle counterclockwise
until tire is lowered to the ground,
the tire can be slid rearward and the
cable is slightly slack.
3. Remove the retainer from the spare tire.
Stowing the spare
1. Lay the tire on the ground with the valve stem facing up.
2. Slide the wheel under the vehicle
and install the retainer through the
wheel center.
3. Turn the jack handle clockwise
until the tire is raised to its original
position underneath the vehicle. The
jack handle ratchets when the tire is
raised to the stowed position. It will
not allow you to overtighten.
Tire change procedure
To prevent the vehicle from moving when you change a tire, be
sure the parking brake is set, then block (in both directions) the
wheel that is diagonally opposite (other side and end of the vehicle) to
the tire being changed.
If the vehicle slips off the jack, you or someone else could be
seriously injured.
On vehicles equipped with Air Suspension, turn OFF the Air
Suspension switch prior to jacking, hoisting or towing your
vehicle.
