Settings -> System (or Settings -> Vehicle) So I used to drive a car with 'always on' headlights -- daytime running lights or whatever. Clarity being an energy saver does not do that (or exactly that) by default. I was delighted to find that we can adjust the AUTO headlight sensitivity. For my preferences, the highest sensitivity works great. It still leaves lights off in broad daylight, but then even come on during the day when diving down a very shady lane. Just right in my book. The other obvious one that most people know (and I really like) is the walk-away auto-lock. Not all like the way this one works, but for my particular habits, this feature has been 100% reliable. Anyway, I'd be interested in other folks use of the available settings, and which they prefer and why.
