For the uninitiated, the ABC (Active Body Control) system is Mercedes's electro-hydraulic suspension which constantly self-monitors and adjusts suspension settings thereby virtually eliminating body roll and pitch in various driving situations including cornering, accelerating, and braking. You'll find it on CL and SL models; however I note that it's been supplanted by Airmatic in most W216 CLs.

And to help adjust ride quality and responsiveness, the driver can select either Sport or Comfort mode via a button next to the shift knob.
We are linking some of the clearest and most-informative ABC threads in the next post
in this thread. Please contribute your own--just link here to the posts if they're already on the forum, and I'll take care of the cleanup. No way can I do this alone.
This post (scroll down) now serves as a general-issues sticky for non-ABC matters. (See the next post
for ABC Threads.) Like it or not, our cars are aging, they are quite complex, and they'll have issues from time to time. We're here to help each other.
NB: Keep in mind that the W220 sedans are mechanically very similar, and vastly more numerous. Therefore the W220 Forum
here at BenzWorld has a greater wealth of information, much of which applies to our cars. See especially their W220 Encyclopedia
