I just bought my ST1 this past Saturday and have spent some time off and on sitting in the car with the owners manual trying to learn some of the features. One that I cannot figure out is the Auto Engine Off option on my display. I know some of the Fords have a feature that shuts the engine off at a stop light and it automatically starts up when pressing in the clutch or gas pedal. My manual doesn't explain what this is or does. All I can do is check and uncheck it on my display. Can someone tell me what this does??
