Fig 1: Identifying Multifunction Display, Level Adjustment Switch And ADS Comfort And Sport Switch (Model 220)

Switching on ignition and starting engine

When the ignition is switched on, the LEDs in the comfort and sport and level adjustment switches light up and when the engine is running indicate the setting selected prior to "ignition OFF".

Display rating

In the event of electrical faults in the AIRmatic or ADS system, the following message appears on the multifunction display in the instrument cluster: "AIRmatic VISIT WORKSHOP! "

The fault is stored in the ADS suspension control module and can be read out using the diagnosis tool.

If the vehicle level at the front axle is more than 50 mm ( 60 mm), or at the rear axle more than 60 mm ( 70 mm) below the normal level, the multifunction display in the instrument cluster displays the warning:

"AIRmatic STOP, CAR TOO LOW ". The display disappears again when the level has risen back to 48 mm or 58 mm ( 58 mm or 68 mm) respectively below the normal level.

Limp-home function

A malfunction in the adaptive damping system causes the ADS to shut down. The suspension is switched to the hardest setting. In the event of a fault in the suspension system or in the level adjustment system, the vehicle attempts to maintain the set level. Manual and automatic level adjustments are no longer possible.

Comfort and sport switch (N72/1s3)

The ADS comfort and sport switch is used to switch between three suspension maps. With the switch at the "Sport I" setting, one red indicator lamp (LED) in the switch (N72/1s3) lights up. With the switch at the "Sport II" setting, both indicator lamps light up.

Level adjustment switch (N72/1s2)

This can be used to raise the vehicle level by 25 mm ( 20 mm). The raised level switch position is indicated by the red indicator lamp (LED) in the switch (N72/1s2). In addition, the multifunction display in the instrument cluster displays: "AIRmatic VEHICLE RISING ".

As long as the multifunction display in the instrument cluster shows the message: "AIRmatic VEHICLE RISING ", the desired vehicle level has not yet been reached.

If the raising of the vehicle is cancelled due to the driving speed, the instrument cluster displays the following message for approx. 10 s: "AIRmatic LEVEL SETTING CANCELLED ".

If the vehicle is raised several times in quick succession, it may happen that the air compressor shuts down temporarily in order to prevent an overload. The raising sequence will then take an unusually long time.
