Dome Defeat
WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
When the instrument panel dimmer switch is in the DOME DEFEAT position, the illuminated entry and exit features do not turn the courtesy lamps on, however the timer for each feature is still active. If the instrument panel dimmer switch is moved out of the DOME DEFEAT position before the 25-second timer expires, the courtesy lamps are illuminated until the 25-second timer has elapsed.
