Manual 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 a manual rearview mirror, push the tab forward for daytime use and pull it for nighttime use to avoid glare from the headlamps from behind.

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