Where is my suspension "up" and "down" switches located? on 2004 Mercedes-Benz SL500

I bought a used SL500 ans it came without an owner's manual. I am having a hard time with my ABC system. I had a new pump installed and I'm still having problems with it.

do you mean an abs pump?
I'm talking about the Active Body Control pump.
the switch is usually in either side of the kick panels or under the dash beside the OBd2 reader
