Mine light up in reverse. Must be the programming changes with newer manufacturing (mine was July 2013). Someone on another thread who went to the dealer to get last driver remembered also noticed that the sideviews blink when opening the trunk with CA, the rear windows go up/down with one touch and the door puddle lights go on in reverse. Sounds like a trip to the dealer will fix this for those in this thread who don't have the reverse lights.
