downward side of the hill.
3. Turn off the air suspension system (the air suspension system is

deployable running boards (if equipped. See
Message center

Driver controls
section).
4. Obtain the spare tire and jack from their storage locations.
5. Use the tip of the jack handle to

6. Position the jack according to the
jack locator arrows found on the
frame and turn the jack handle and
extension tool assembly clockwise.
Note:
Use the frame rail as the
jacking point, NOT the control arm.

further than 1 inch (2.5 cm) off the
ground when installing the spare tire.
