Enhance your Auto-Dimming Mirror experience by adding the Exterior Auto-Dimming Mirrors with Approach Light.* Open or unlock the doors with the keyless entry system and LED lights located behind the Subaru logo in each exterior mirror help to light the way. Light is cast down from all four doors and onto the ground next to and towards the rear of the vehicle. When in traffic, the Exterior Auto-Dimming Mirrors help add to a safer driving experience by reducing headlight glare on the exterior mirrors. This occurs when excessive light is detected from the rear of the vehicle. The dimming level of the exterior mirrors is regulated by the level of light detected by the Interior Auto Dimming mirror. *Requires accessory interior Auto-Dimming Mirror.
