It's raining here but not terribly dark.   I just pulled the truck out of the garage, locked it, and then walked down the road a ways.  A few minutes later I came back.  When I approached the truck with the FOB in my hand, nothing happened.  The proximity wake-up has never worked for me.  I then hit unlock and the headlight animation ran successfully, and the headlights stayed on.  I got in the truck, started it, and then the headlights went off (it's too light outside).  I'll try to include a picture of my settings.  I have a video (*.MOV), but not sure how to attach it.
