Driving If a load is added to, or removed from the vehicle, the load leveling feature of the air suspension system will adjust the suspension to keep the vehicle at a constant level. When exiting the vehicle, the air suspension will automatically lower the vehicle to its lowest height to provide easier exit. You may hear a buzz or click from the air suspension system when the ignition is turned off. The air suspension system will stay active for 40 minutes after the ignition is turned off to accommodate any load changes. (The air compressor may run when the vehicle is off; this is normal.) The air suspension shut-off switch is located behind an access panel on the left rear quarter trim panel, near the liftgate. To remove the panel, turn the control counterclockwise. On vehicles equipped with air suspension, turn the air suspension and the ignition switch off prior to jacking, hoisting or towing your vehicle. Press the bottom portion of the switch to turn off the air suspension. 253 2006 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus)
