• Depressurize AIRmatic components (suspension struts, valve unit, main memory) before removal using Star Diagnosis, if necessary, discharge entire system. The components or the entire system must not  be discharged by unscrewing pressure lines!
• Soiled pressure line connections must be cleaned before unscrewing. Do not use detergents or solvents as these may damage the pressure lines.

  Seal off the pressure lines and the connections on the components immediately with blind plugs.

• Only use flare nut wrenches or special tools to unscrew the pressure lines.
• Removed or slackened off suspension struts may not be filled with compressed air and they must not be pushed together!
• When installing the spring struts, take particular care to ensure that the residual pressure valves, protective boots and the ADS valves with their electrical connections are not damaged.
• The suspension struts must not be loaded (no spring movement) between installation of the suspension struts and the time when the system is filled.
• Before driving the vehicle through washing cubicles or over workpits, lifting platforms or ramps with uneven surfaces, set the vehicle level switch to raised level. A high level is reached when "Air spring vehicle rising!" is shown in the multifunction display.
• If the vehicle is to be left parked for a long time, turn the wheels to the straight-ahead position otherwise a pressure loss may occur.
• Emergency buffers that are used for transport or shipment on the suspension struts are available from the replacement part department.

Emergency buffers may only  be used for maneuvering.
