Air suspension system is operational with ignition switch in RUN position, and has limited operation for 40 minutes after ignition is turned off. The air suspension switch, located in left rear corner of vehicle, must be turned off when vehicle is being hoisted, towed or jump-started.
A CHECK AIR SUSPENSION warning light is located in message center, to right of instrument cluster. Warning light stays on when air suspension is turned off or a system malfunction is detected.
Air required for leveling vehicle is distributed from air compressor to front (if equipped) and rear fill solenoids through nylon air lines. Air system can be pneumatically separated from side to side by control module activation of rear gate solenoid. This separation provides vehicle stability during roll conditions.
For safety during loading and unloading, vehicle height is memorized and maintained when any door is opened. Vehicle will return to commanded height when doors are closed or vehicle speed exceeds 10 MPH.
