Headlights - Automatic Twilight Sentinel: Description

Automatic twilight sentinel determines automatic on/off control of exterior lights, and holds exterior lights on for a period of time after ignition switch is turned off. Automatic twilight sentinel uses reading from ambient light sensor to determine whether Daytime Running Lights (DRL) or exterior lights (low beam headlights at full intensity) should be on. Twilight sentinel also keeps lights on for a delay period of 3-180 seconds when the gearshift lever is in Park, ambient light sensor reads darkness, and ignition is turned off.

Twilight sentinel switch cannot be turned off permanently. If moved to OFF position, it will automatically return to ON position when released. If gearshift lever is in Park and ignition is turned on, headlights can be cycled off by moving switch to OFF position and then releasing. Headlights will return to automatic operation when gearshift is moved out of Park.
