Light Sensor Exterior Lighting Battery Saver If the parking lamps or headlamps have been left on, the exterior lamps will turn off about 10 minutes after the ignition is turned to OFF. This protects against draining the battery in case you have accidentally left the headlamps or parking lamps on. The battery saver does not work if the headlamps are turned on after the ignition is turned to OFF. If you need to leave the lamps on for more than 10 minutes, use the exterior lamp control to turn the lamps back on. The light sensor for the DRL and AUTO headlamp feature is located on top of the instrument panel. If you cover the sensor, it will read dark, and the exterior lamps or the Headlamps Suggested message will appear on the DIC whenever the ignition is on. 3-20
