So while waiting to pick up my daughter I started playing with the menus. Lo and behold, I have winter mode. So I guess my 21 Ultimate(U.S) has a Battery heater? My next question is, do I wait for freezing temps to put it on or does it not matter and I can put it on now? From what I read it only activates at a certain temperature.
Ya, it doesn't do a thing until it's cold enough to activate. You're perfectly safe if you just leave it on. I would caution you slightly that (in the 2019 anyway) Winter Mode has a habit of turning itself off once in a while so it's worth checking in on the settings occasionally.
