Do our cars have the automatic seatbelt adjustment feature when you use the seatbelt? Mine isn't adjusting, Nor I there a manual adjustment feature. Could it be a blown fuse?

Not sure what you mean by "manual adjustment feature", but my 2008 W221 does not initially snug the belt like the new cars do.

By manual I mean press a button and it adjusts by hand like on standard cars. So the belt guide only moves if you raise our lower the seat?

The vehicle automatically adjusts the seat belt height for the driver's and passenger's seats as well as for the rear outer seats. The seat belts must be fastened in order for the adjustments to occur.

I think what you mean is a motorized tightening of the seatbelt after you first fasten it. I had a loaner 2016 e350 that did this, but I don't think that's a feature on the 2007 S550.

No it's not. New S has, and I don't like it. Sometimes newer isn't always better.

It is on the 2013. Probably was added in the 221 refresh.

I ment the elevation guide of the seatbelt on the B pillar. I'm going to try and "shorten" my shoulder today and see if it moves.

See post #4. It comes directly out of the 2007 owners manual.

This is in the service campaign thread that is stickied, it's worthwhile to read through it.
