How can I tell if my Mercedes has 4MATIC®?
4MATIC® is a Mercedes registered trademark for all-wheel drive. Usually, if the vehicle features 4MATIC®, there will be an emblem on the right side of the trunk. See illustration below.
How can I tell if my Mercedes S-Class is equipped with AIRMATIC® or ABC?
AIRMATIC® is a Mercedes trademark for air suspension. ABC stands for Active Body Control. ABC was a rare option on all S-Class models. ABC, however, was standard on all S-600, S-55, S-63, and S-65 models. You can tell which suspension you have by opening the hood of your car and examining the top of the shock absorber.
If the car is equipped with AIRMATIC, you will have obvious 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.
