S-Class Airmatic or ABC
AIRMATIC is a term unique to air suspension systems of Mercedes-Benz vehicles, that can be used to adjust the ride height and firmness. ABC stands for Active Body Control and is a suspension driven by either oil or hydraulic fluid.
ABC was a rare option on all the S-Class models. ABC however was standard on all S-600, S-55, S-63, and S-65 models.
How can I tell if my Mercedes S-Class is equipped with AIRMATIC or ABC?
The following are a few ways to tell whether your vehicle has got S-Class AIRMATIC or ABC:
1) Open the hood of your car and examine the top of the shock absorber. If the car is equipped with AIRMATIC, you will have clear air lines leading from the top of the shocks.
If your car is equipped with ABC, you will have small black electrical plugs leading into the top of both shocks.
2) If your car has ABC, there will be a button on the center console marked “ABC Sport”. If it has standard AIRMATIC, the button will show a picture of a spring with arrows.
