Wish this car had a real off switch. That way I could work on the car and not drain the battery.
Put the key fob far away, if it is in your pocket while you wash or fiddle with the car, it keeps the ECU awake and waiting to do something. I do this now always when I work on the car. Lets the ECU go to sleep and stay asleep so the battery does not drain.
