Light Sensor Interior Lamps Instrument Panel Brightness Control This feature controls the brightness of the instrument panel lights. The knob for this feature is located to the left of the steering wheel on the instrument panel. This knob is also used to control the exterior lamps. See "Exterior Lamps" listed previously in this section for more information. Turn the knob clockwise to brighten the lights or counterclockwise to dim them. 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. Illuminated Entry The illuminated entry system turns on the courtesy lamps and the backlighting to the door controls and to the exterior lamp knob when a door is opened or if you press a remote keyless entry transmitter button. Since the illuminated entry system has a photocell, this means that it must be dark outside in order for the courtesy lamps or backlighting to turn on. The courtesy lamps turn off approximately 20 seconds after the last door is closed or after the ignition is turned to RUN. Exterior Lighting Battery Saver If the parking lamps have been left on, the exterior lamps will turn off approximately 10 minutes after the ignition is turned to LOCK or ACCESSORY. This protects against 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 off and then back on. To delay the lamps from turning off, see "Twilight Sentinel" in the Index. 2-46
