Automatic Dimming Rearview Mirror
The vehicle has an automatic dimming inside rearview mirror.
Automatic dimming reduces the glare of headlamps from behind you.
If the vehicle has a rear vision camera (RVC), see Rear Vision Camera (RVC) for more information.
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.
