Air Spring Service Precautions and Procedures

CAUTION: Power to the air system must be shut off by turning the air suspension switch (in luggage compartment) off or by disconnecting the battery when servicing any air suspension components.

WARNING: Do not attempt to install or inflate any air spring that has become unfolded.

CAUTION: Failure to follow the procedures below may result in a sudden failure of the air spring or suspension system.

Procedures to follow when working with the Air Springs:
- Any air spring which has unfolded must be refolded over the piston as shown, prior to being installed in a vehicle.
- The air spring refolding procedure should only be used to service an air spring which has never supported the vehicle's weight while in the improperly folded position.
- Improperly folded air springs found on vehicles during pre-delivery inspection or after customer mileage must be replaced.
- Do not attempt to inflate any air spring which has been collapsed while un-inflated from the rebound hanging position to the jounce stop.
- When installing a new air spring, care must be taken not to apply a load to the suspension until springs have been inflated using air spring fill procedure.
- When front air springs are replaced the height sensor must be checked and replaced if damaged.
- After inflating an air spring in hanging position, it must be inspected for proper shape.
