Automatic Dimming Rearview Mirror
The vehicle may have an automatic dimming inside rearview mirror.
Automatic dimming reduces the glare from the headlamps of the vehicle behind you. The dimming feature and the indicator light come on each time the vehicle is started.
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.
