If it is genuine Mercedes the instructions should be in your owners manual. Check here http://repairpal.com/automobile-owners-manuals-online or try this link you may be able to down load a free copy of the owner's manual for your vehicle http://www.autousermanual.com/
I have the owner manual, BUT the problem that I need to get to the dealer to do it and the dealer need $1400 to do it for me, and I don't like anyone to take my money for no reason. So what I was looking for someone to tell me how to turn it on without the Dealer word.
