I have a Canadian '95 E420, and on my center dash, there is a button for snow chain. I've never had the need to use the button, and was curious as to what it exactly does. The manual very vaguely states that it "increases traction"...and also mentions that if your car is equipped with ASR, the button MUST be depressed if you are to be using snow chains. I was wondering if that snow chain button actual deactivates ASR, since I can't see how the jerky movements caused by ASR could be helpful if one has snow chains on. I've always wanted to test it out when I was at home, but it keeps slipping my mind. Any bits and pieces of information would be appreciated. Thank you!
