They and all the car accessories run off the 12 volt battery, which is charged by the main drive battery. Go into settings on the center screen. There is a screen that is all light, lock, and horn settings. It's been several years now, but I turned almost everything off. My outside lights go off as soon as the car does.1 can the time the headlights are on after turning the car off be reduced? Do the headlights run off the main drive battery?
2 I am confused about when the air conditioner is on. Can someone explain the operation? Do I need to turn on the heat/air conditioner if I want it cooler?
