WARNING:
Do not remove an air spring under any circumstances when there is pressure in the air spring. Do not remove any components supporting an air spring without either exhausting the air or providing support for the air spring to prevent vehicle damage or personal injury.
CAUTION:
The suspension height D dimensions are for reference only. The vehicle attitude must be controlled by the correct dimensions to prevent vehicle damage.
NOTE:
Improper air suspension ride height D dimension can be caused by an air suspension system that is incorrectly set.
- Position the vehicle on a level surface over an open repair pit.
- Open the luggage compartment and verify that the air suspension switch is turned on.

- Measure the ride height D dimension.
- If ride height dimension D is not within specification, use the scan tool to vent or fill the air suspension to the correct dimension.
- Use the scan tool to monitor the suspension height sensor voltage PID.
- Loosen the height sensor ball stud bracket retaining nuts.
- Slide the ball stud bracket until the height sensor voltage PID is equal to 2.80 volts.
