DESCRIPTION
Note. Electronic air suspension is available only on models manufactured prior to 7/25/97.
Rear air suspension is air-operated and computer-controlled. Optional air suspension system replaces conventional steel coil springs and provides low spring rates for improved ride and automatic rear load leveling.
Two air springs replace conventional steel coil springs and support vehicle load at rear wheels. Air springs are mounted on the rear axle spring seats and to the frame upper spring seats, much like conventional steel coil springs.
OPERATION
Rear air suspension system is operational with ignition switch in RUN position and has limited operation for one hour after ignition is turned off. The air suspension switch, located in jack storage area under right rear interior trim panel, must be turned off when vehicle is being hoisted, towed or jump-started.
A CHECK AIR SUSPENSION warning light is located in warning light indicator panel, to right of instrument cluster. Warning light stays on when air suspension switch is turned off or a system malfunction is detected.
Air required for leveling vehicle is distributed from air compressor to the air springs through a nylon air line, which runs from compressor drier through a "Y" fitting to each individual air spring.
