There are 2 ways to reset the air suspension..The first one is to remove the access plastic panel located on the drivers side in the very back of the vehicle After you remove the panel you will find a rocker switch marked on/off.Turn it off wait about 30 seconds then turn it back on.It is also very important to turn this switch off before raising or using a jack to lift the vehicle off the ground. You can also hit the reset button on the dashboard when the Air suspension is illuminated on the readout of the system check.
