Vehicle height raises [When starting engine, if vehicle height of vehicle rear continues for 30 seconds or more in a status that is 15 mm (0.59 in) or less than standard vehicle height] 

1. Vehicle height sensor detects vehicle height status, and transmits this information to air levelizer control module.
2. Air levelizer control module turns air compressor relay ON and operates air compressor.
3. Air compressor charges air in air chamber of shock absorber.
4. Vehicle height raises, and control is complete when status is -1 mm (-0.04 in) of standard vehicle height value.

Vehicle height lowers [When starting engine, if vehicle height of vehicle rear continues for 30 seconds or more in a status that is 15 mm (0.59 in) or more of standard vehicle height] 

1. Vehicle height sensor detects vehicle height status, and transmits this information to air levelizer control module.
2. Air levelizer control module turns exhaust solenoid of air compressor ON.
3. Air compressor discharges air from air chamber of shock absorber.
4. Vehicle height lowers, and control is complete when status is +1 mm (+0.04 in) of standard vehicle height.
