Automatic Dimming Rearview Mirror

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.

See OnStar Overview.

Cleaning the Mirror

Do not spray glass cleaner directly on the mirror. Use a soft towel dampened with water.
