Interior, Auto-Dimming: Notes

The interior auto-dimming interior mirror automatically darkens to reduce the glare caused by headlamps reflecting in the mirror from behind the vehicle. The auto-dimming feature is active any time the ignition is on and the amount of dimming will vary with different ambient lighting conditions.

The auto-dimming interior mirror uses 2 photoelectric sensors. The forward facing sensor located on the front of the mirror (facing the windshield) is used to detect ambient lighting conditions. The rearward facing sensor, located at the top of the mirror glass (facing the driver) is used to detect glare from behind the vehicle during nighttime conditions. When the forward facing sensor detects daytime conditions, the rearward facing sensor is inactive and the mirror stays in a high reflectance mode. When the forward facing sensor detects nighttime conditions, the rearward facing sensor is active and detects glare from the headlights of vehicles approaching from the rear, or other glare producing light sources. To provide increased visibility when backing up, the interior rear view mirror automatically returns to a clear state whenever the vehicle is in reverse.
