ELECTROCHROMIC (EC) OPERATION (auto dimming feature) 

The automatic dimming feature detects forward and rear light conditions and adjusts the reflectance level of the mirror to eliminate unwanted glare by the use 2 photoelectric sensors. The feature can be disabled by depressing the Left and Right buttons together for more than 5 seconds. The disable command will only remain in effect until the ignition is turned off. The EC function will automatically return to ON with each ignition cycle.

When the forward sensor detects daytime conditions, the rear sensor is inactive and the mirror remains in a high reflectance state.

When nighttime conditions are sensed by the forward sensor, the rear facing sensor is active and detects glare from rearward approaching vehicles or other glare producing light sources. The mirror will automatically adjust to a low reflectance state to remove the unwanted glare from the inside rear view mirror. The mirror will automatically return to a high reflectance state whenever the vehicle is placed in REVERSE to ensure a clear view when backing up.
