Manual Rearview Mirror
Adjust the inside rearview mirror for a clear view of the area behind your vehicle. To avoid glare of the headlamps from behind, push the tab forward for daytime and pull it for nighttime use.
Vehicles with OnStar have three control buttons at the bottom of the mirror. See your dealer for more information about OnStar and how to subscribe to it. See OnStar Overview.
