AIRMATIC is a unique term for the air suspension system of Mercedes-Benz vehicles, which can be used to adjust ride height and firmness. ABC stands for Active Body Control and is a suspension driven by oil or hydraulic fluid.

The ABC was a rare option on all S-Class models. However, ABC was standard on all S-600, S-55, S-63 and S-65 models.

The following are some ways to tell if your vehicle has an S-Class AIRMATIC or ABC:

1) Open the hood of your car and check the top of the shock absorber. If the car is equipped with AIRMATIC, it will have clear air lines running over the shock absorbers.
