I know it's a special feature of the truck.. My 2013 F150 has that too... I think I used it once.. It turns on when it's in the garage.. I park the truck in the garage. Didn't want that to happen every time I started the truck in the garage.
Just went back to my roots and turn them on when it's needed and turn them off when not. :)
Not trying to be snarky about it, as you and I did "pay" for that feature... Well, it came in an option package, so no choice unless you didn't want the whole package, which I did for the other features I use all the time..
Anyway, I still miss the high beams being a big button you pressed with your left foot under the parking brake pedal! :) :)
