Do not bleed the air suspension system until the vehicle has been raised.

When disconnecting a Voss type fitting from any air suspension component, do not remove it from the air hose being disconnected.

Do not remove the nipple from the air hose. When removing the nipple from the hose, there is a high probability of scratches appearing on it, which may subsequently lead to air leakage from the system.

Dismantling

1. Raise the front of the vehicle and support it with stands.

CAUTION: Do not work under a vehicle supported solely by a jack or lift. Always support the vehicle with safety stands.

2. Release air from the air suspension system.
