According to my service tech, my cars presafe function seems to be activating for some unknown reason.

Sitting at a traffic light at a complete stop, all of a sudden the seat belt tightens down on me.

Parking in my garage, come to a stop, put into park and seat belt tighten downs on me.

Give me a break. This stuff all sounds good in the brochure, but it takes them years to get a the GOOFS out of it.

This one will be interesting to get fixed. I can see the mechanical genius scratching his head on this one. To avoid getting the standard Mercedes response of "UNABLE TO DUPLICATE", I plan on driving the service manager around until it happens. It shouldn't take long.

Is it the SL600 that is giving you the problems? I did not realize the SL had pre-safe. I thought it was an S class only function.

I didn't know it had it, but the rep sure thinks it does.

First I've ever heard of it having it, agree it's only the S. What worries me is all this guessing haapens while they're trying to fix your car as well.

Let's just say he is WRONG! No PRE-SAFE in the SL.

What in the world would cause the seat belt to tighten while at a stop. Not stopping at a STOP!

My driver's seatlbelt locked up twice -- both times the dealer replaced the units.

Whoever told you that is dumb. There is no Pre-Safe on SL. Maybe the seatbelt sensors, ( that tighten up and sense if you hit the brakes or whatever) or screwed up.
