I believe the switch for the mirrors has to be in the left or right position if it is in the middle they will not work.
I felt the same exact way at first, but it really helps when you park your car backwards (which I do religiously!)Thanks for this information. I've been trying to figure out how to turn the auto-tilt feature off. I think the mirrors are less usable for backing when they are tilted down than they are in the standard position. Just my thoughts on it.
