Fig. 1.12. Appearance and functional features of the automatic rearview mirror
At night, if there is a large difference in the intensity of the ambient light and the light falling on the interior rearview mirror from the headlights of vehicles driving behind, the system automatically reduces the reflectivity of the mirror and thus dampens the brightness of the light in the mirror (Fig. 1.12).
Table 1.3. Purpose of the elements of the automatic rearview mirror
| Element | Purpose |
| Ambient Light Detection Sensor (sensor number 1) | Determines the intensity of light surrounding the vehicle |
| Rear light detection sensor (sensor number 2) | Determines the intensity of light falling on the interior rearview mirror |
| LED | Turns on to inform the driver that the mirror is in AUTO mode |
| Mode selection switch (AUTO, OFF) | Selects the rearview mirror operating mode: AUTO or DAY |
| Electrochromic mirror element | Changes the reflection coefficient |
