Brightness control

The instrument panel is illuminated when the lights are switched ON. A phototransistor is installed in the auxiliary instrument to calculate the necessary brightness (display, indicator and warning lights, scales, needles).

The brightness value calculated in the instrument panel is output on the K-CAN (e.g. for the Central Information Display). The dim can be adjusted individually in the auxiliary instrument, using the left button. When the vehicle lighting is switched on, these individual settings and the phototransistor are used to control the dimming. When the vehicle lighting is switched off, dimming is only controlled by the photo-transistor (display brightness specified by the ambient light).
