Turn Signals and Headlights Even with the automatic lighting feature turned on, we recommend that you turn on the lights manually when driving at night or in a dense fog, or when you enter dark areas such as long tunnels or parking facilities. Do not leave the light switch in AUTO if you will not be driving the vehicle for an extended period (a week or more). You should also turn off the lights if you plan to leave the engine idling or off for a long time. LIGHT SENSOR Automatic Lighting Off Feature This feature turns off the headlights, fog lights, parking lights, taillights, side marker lights, license plate lights, and instrument panel lights within 15 seconds of removing the key from the ignition switch and closing the driver's door. The automatic lighting off feature activates if you leave the headlight switch in the or position or if the lights are turned on by setting the switch in the ''AUTO'' position, and you remove the key, then open and close the driver's door. The automatic lighting feature is controlled by a sensor located on top of the dashboard. Do not cover this sensor or spill liquids on it. 118 2010 RDX
