Automatic Dimming Rearview Mirror
The vehicle has an automatic dimming inside rearview mirror.
Automatic dimming reduces the glare from the headlamps of the vehicle behind you.
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 the OnStar Owner's Guide for more information about the services OnStar provides.
