Electro-Chromatic Mirror.

The Electro-Chromatic Mirror (ECM) provides protection to the driver from the glare caused by the headlamps of vehicles behind. The ECM senses and reduces light intrusion from following vehicles with its dimming function to aid in reducing eye fatigue during light night driving. It also incorporates a compass, which can be handy in knowing the direction of travel.

Available on the Elite and Highlander variants.
