Roadside Emergencies 1. Block the wheels (both front or both rear) on the opposite end of the vehicle from the wheel being changed. If on a grade, block both wheels on the downward side of the hill. 2. Turn off the air suspension system. The air suspension system is controlled through the message center. Refer to Air suspension system in the Driving section for more information. Also, turn off the deployable running boards (if equipped). Refer to Message center in the Instrument Cluster section. 3. Obtain the spare tire and jack from their storage locations. 4. Use the tip of the jack handle to remove any wheel trim. Loosen each wheel lug nut one-half turn counterclockwise but do not remove them until the wheel is raised off the ground. 5. 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. 6. Lift the vehicle so the tire is no further than 1 inch (2.5 cm) off the ground when installing the spare tire. 280 2012 Navigator (nav) Owners Guide, 1st Printing USA (fus)
