Twilight Sentinel

When the twilight switch is place in an ON position, the twilight sentinel keeps the lamps on for a delay period (3 to 180 seconds), when the vehicle is in PARK, the ambient light sensor indicates darkness and the ignition switch is turned to the OFF position. The twilight sentinel feature does not affect the operation of the Daytime Running Lamps (DRL).
