Base Courtesy and Extended Lighting

WARNING: This page is about a different car, the 2003 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.

The base courtesy lighting feature provides interior lighting for the convenience of the vehicle's occupants. The courtesy lamps consist of the map/dome lamps for the coupe and the map lamps for the convertible. All lamps designated as courtesy lamps will be illuminated whenever the GEM detects that the driver or passenger doors become ajar, by means of the driver or passenger door ajar circuits. The courtesy lamps will also be illuminated when the GEM detects that the dome lamp switch has been activated, by means of the dome lamp switch circuit.

The extended courtesy lighting feature provides temporary extended illumination of the courtesy lamps after the customer has entered the vehicle. The courtesy lamps will remain illuminated for 25 seconds after the GEM detects that the drive and passenger doors are closed, as detected by the door ajar circuits. The extended courtesy lighting feature will be terminated after the 25 second time-out period, of if the GEM detects that the ignition switch has been moved from the OFF position to either the RUN, ACC, or START positions.
