AUTOLAMPS Function
The 'AUTO' autolamps function is a driver assistance system. The driver can override the system operation by selection of side lamp or low beam headlamp on.
The autolamps system uses a rain/light sensor which is connected to the BCM/GWM assembly via a LIN bus. The BCM/GWM assembly reacts to the signals from the rain/light sensor and activates the exterior lamps as required.
The light sensor is incorporated in the rain/light sensor located on the inside of the windshield, below the rear view mirror. The wiper system also uses the rain/light sensor for automatic wiper operation. For additional information, refer to: Wipers and Washers (501-16 Wipers and Washers, Description and Operation).
The light sensor measures the ambient light around the vehicle in a vertical direction and also the angular light level from the front of the vehicle. The rain/light sensor uses vehicle speed signals, wiper switch position and the park position of the front wipers to control the system.

Operation of the autolamps requires the ignition to be on (power mode 6 or above), the left steering column multifunction switch to be in the 'AUTO' position and a lights on request signal from the light sensor. When the autolamps system is active, the side lamp warning indicator in the IC will be illuminated.
