Automatic Dimming Rearview Mirror

To adjust the inside rearview mirror, hold the rearview mirror in the center and move it to view the area behind the vehicle.

For vehicles with an automatic dimming rearview mirror, the mirror will automatically reduce the glare from the headlamps from behind. The dimming feature comes on when the vehicle is started.

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