The interior rearview mirror can be dimmed according to the brightness of the light (electrochromizing technology).
The operating principle of this system is based on comparing the illumination brightness values corresponding to the signals of two sensors:
- sensor A on the side of the windshield;
- sensor 8 from the side of the mirror.
Note. The exterior mirrors can also be equipped with this system. In the atom case, dimming is switched on by the interior rear guide mirror. Exterior mirrors but have light brightness sensors.
