I had a 2015 MKC that had a proximity sensor that would turn on the welcome mat light and such when I approached the vehicle. Does the MKX do the same because I can't get it to work. I've tried locking the door from the inside switch, the door handle and the fob walking far away and coming back much later and I don't see it light up unless I press the unlock on the fob. Is this correct? Anything I can do?
