I've had the car 6+ yrs and I discovered a new scenario yesterday. Got self serve gas which I never do, always full in NJ. So I pull my car into a space, shut her off, then put the ignition back on to enter the odo info into my droid app. Exit the car and lock etc. when I get back I go oh s***. My drl's are on, as is the entire ignition, with a key with a slash icon.
that coulda been a dead batt.....
