Hi, everyone. I just got a HCH last night and while the salesman was nice and friendly, he was clearly unable to explain how my new engine works and what the gauges mean to me. What does the green "Auto Stop" light mean when I'm idling at a light? And am I supposed to be paying attention to the "Assist" bar as it rises and falls? I love the car and am anxious to see my next gas bill, but I'm not interested in trying to squeeze another few miles out of the car if it requires a lot of effort. Any feedback would be greatly appreciated!
