Never knew this dial existed as there are not many ML 63 seeking help on this issue.

I will check the wiring diagram so give me some time with it.

AARG, I looked high and low at all the wiring diagrams and could not find anything on that dial. Do you know what the official name of it?

I also looked at your owner's manual and could not find the explanation of it. Do you know the page # where it explains it?
