This has happened twice and does go away, but I still have a question of why it happens. The temperature is close to 10 degrees F (in Northeast). I turn on my 745 and I see in the center display area a yellow icon that looks like a car tilting to one side. It stays on. I drive 10 minutes and put the car in garage. Next morning the icon is gone. I went to the i–drive indow, for car data, to look for any maintenance errors and saw none.

Any idea what this icon means? In general is there a place where ALL icons are explained?
