I've noticed recently that my front footwell lights are on at night when driving. It's not every trip. I don't mean the coloured ambient lighting which can switch off. These are the white lights that go on when you open the car door. Is there somewhere to turn these off? The manual states they should go off after 20 secs after all doors closed/locked. I tried holding the center front interior courtesy light until it flashes but that didn't do anything.
