Hey guys,

So I've had my lovely SLK 200K for about half a year now and I've come to a point where I need answers.

You see, I never really understood what functions all of the buttons have until two or three days of ownership. However, there is one button which I still can't figure out. It's the button on the picture, the one positioned to the right. It has a car and a hook on it and it says "Off".

So if anyone could help me out on this one, I'd be most grateful

 

That's your tow-away alarm.
It sounds an alarm if someone tries to tow your car away.
It's armed when you lock your car. Switch it off (light out) if you need to tow it.
At least that's how it works on my cls.

 

Aha!! Thank's a lot for the help!
