yellowblue If it's dark enough outside and the Twilight Sentinel control is off, a HEADLAMPS SUGGESTED message will display on the Driver Information Center (DIC). This message informs the driver that turning on the exterior lamps is recommended (it's become dark enough outside to require the headlamps and/or other exterior lamps). Turning on the Twilight Sentinel, the headlamps or the fog lamps will remove the HEADLAMPS SUGGESTED message. Light Sensor Exterior Lighting Battery Saver If the manual parking lamp control has been left on, the exterior lamps will turn off approximately 10 minutes after the ignition is turned to LOCK or ACCESSORY. This protects draining the battery in case you have accidentally left the headlamps or parking lamps on. If you need to purposely leave the lamps on for more than 10 minutes with the ignition in LOCK or ACCESSORY, turn the exterior lamps control knob off and then back on. To delay the lamps from turning off, see "Twilight Sentinel" in the Index. Interior Lamps Instrument Panel Intensity/Brightness Control The digital displays automatically dim when it becomes dark outside and your lights are on. When it's dark, the brightness control can be manually adjusted by turning the exterior lamps control knob counterclockwise to dim and clockwise to brighten the lighting. The digital displays automatically brighten when it becomes light outside, although backlighting will remain active at the selected brightness as long as the lights are on. The light sensor for the Daytime Running Lamps (DRL) and the Twilight Sentinel is located in the center of the front defogger grille. If you cover the sensor, it will read "dark" and the lamps will come on. 2-43
