On vehicles with an automatic dimming inside rearview mirror the automatic dimming reduces the glare from the headlamps of the vehicle behind you.

Vehicles with OnStar have three control buttons located at the bottom of the mirror. See your dealer for more information about OnStar and how to subscribe to it.
