The air suspension system is under pressure (up to 10 bar, or 150 lbf/in). Verify pressure has been relieved and disconnect power to the air suspension system prior to disassembly. Do not allow dirt or grease to enter the system. Always wear standard hand, ear, and eye protection when servicing the air suspension system.
Reading this manual signifies your agreement to the terms of the general release, waiver of liability, and hold harmless agreement, the full text of which is available at
Not to be stored below 5°F (-15°C) or above 122°F (50°C).
Avoid damage to air lines and cables.
Removal and installation is only to be performed by fully qualified personnel.
Use car manufacturer’s diagnostic software.
Damage to the vehicle and air suspension system can be incurred if work is carried out in a manner other than specified
in the instructions or in a different sequence.
To avoid the possibility of short circuits while working with electric components consult your owner's manual on how to
disconnect your battery.
