Ambient Light Sensor

AMBIENT LIGHT SENSOR

An ambient light sensor is located in the instrument cluster, adjacent to the alarm indicator. The ambient light sensor is a phototransistor which measures the available ambient light.

The phototransistor measures the ambient light (lux) level and passes a signal value for the available light level to the instrument cluster microprocessor. The instrument cluster software adjusts the display brightness of the message center and information display LCD's accordingly to ensure that the displays are clearly visible during day and night time driving.
