System Operation - Exterior Auto-Dimming

WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

The LH exterior mirror is equipped with an auto-dimming feature. This feature automatically reduces the glare caused by bright light behind the vehicle during nighttime conditions. The interior auto-dimming mirror supplies voltage and ground to electronically darken the LH exterior mirror glass based on ambient lighting conditions. The reflectance level of the mirror glass is variable and depends on the amount of rear glare in relation to ambient light conditions in front of the interior mirror.

To provide increased visibility when backing up, the interior auto-dimming mirror glass and LH exterior mirror glass automatically returns to a high reflectance mode whenever the vehicle in REVERSE, regardless of exterior lighting conditions.

An interior auto-dimming mirror concern can affect the operation of the LH exterior mirror auto-dimming mirror.
