Re: A couple questions about my new HCH
Hi, and welcome!
To answer the first question, if you have come to an auto-stop, try not to creep forward if you can tell you will still be in a situation where you are not likely to be moving anywhere just yet. The auto-stop feature will not re-engage unless you get back up to about 10 miles per hour before the next stop.
As to the fan cooling off the engine once the car is stopped, I haven't actually timed it, but there were times when I went back to check on my car, curious to see if the fan was still on or not. I think it usually only stays on a couple of minutes. I usually only notice that the engine fan goes on in warm weather or after a really long trip.
Best of luck with your new car.
