I just bought a used 2013 MKZ - I know, I'm behind the times from most of you guys. I can't figure out how to get my mirrors to fold. I looked through the steering wheel left buttons & didn't see anything on there about the mirrors? Any help is greatly appreciated (just upgraded from my 09 Galant). Did I miss the option? The dealership guy said they folded in but I'm stumped (and/or just dumb)...
