The small switch on the interior rearview mirror is used to toggle the auto-dimming function. Pressing the switch can turn the auto-dimming feature on or off. When the indicator light is illuminated, it means the auto-dimming function is activated, and the interior rearview mirror will automatically reduce reflection based on the intensity of the headlights from vehicles behind. There are two types of anti-glare features for interior rearview mirrors: one is manual, which suppresses glare through optical principles. This type of mirror uses a dual-reflectivity glass. When the driver feels the reflected light is too strong and dazzling, they can manually adjust the mirror angle by moving the adjustment lever, causing the mirror to tilt. In this position, the mirror's reflectivity decreases, naturally reducing the light intensity.
