Also, it's smart enough not to turn off when the engine is cold - it needs to be at full operating temperature before it becomes active. If it is very hot out and there is lots of A/C load, it does not turn off. If you start creeping (you can feather the brake to keep it from engaging), it does not stop. If you sit for too long with the A/C running or if the batter falls to a certain level, it will restart the engine. The logic sitting behind it seems really robust and generally well thought through. It was unnerving at first, but now I like it. BTW, when you put the car into sport mode (which is really cool how it remaps shift points and throttle response), auto stop is disabled; plus you can disable it in a situation where it would be annoying, such as in stop and go traffic.
