The mirrors on my ML350 stoped folding after I lock the car. How can I get that feature back?

 

I've found on my O8 ML. That the mirrors won't fold in if a door is open when I hit the lock on my key fob. If all doors are closed then they fold in. Also if the mirrors don't fold in then hit the lock button again and they will.

This assumes that you have the folding mirror option turned on.
