Just a warning to all. The car's I have owned over the past 10 years aways had a feature to shut off headights or other accessories if left on for a certain amount of time or the battery was running low. I came home last night an turned the headlights on to fiddle with some settings on the dashboard. As can be expected these days, I left he headlights on. I happened to go outside 2 1/2 hours later and noticed the headligts were still on. I hooked up my charger and the amp reading showed the battery was pretty tired. The moral of the story is "don't leave your headligts on or you might be stranded the next morning".
