Principles of Operation: Autolamps
WARNING: This page is about a different car, the 2005 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
The autolamp system, controlled by the vehicle security module, supplies voltage to the same circuits used by the headlamp switch to power the exterior lamps when low light conditions are detected. The autolamp system provides light sensitive automatic on/off control of the exterior lamps normally controlled by the headlamp switch. The autolamp system keeps the exterior lamps on for a pre-selected period of time after the ignition switch is turned off. The pre-selected time lapse is adjustable up to approximately 3 minutes. Refer to the owner literature for further information about the autolamp time lapse adjustment.
