Automatic Dimming Rearview Mirror

The vehicle may have an automatic dimming inside rearview mirror with OnStar® and/or a compass display. Automatic dimming reduces the glare from the headlamps of the vehicle behind you. The dimming feature comes on and the indicator light illuminates each time the vehicle is started.

Vehicles with OnStar have three additional control buttons located at the bottom of the mirror. See your dealer/retailer for more information on the system and how to subscribe to OnStar. See the OnStar® owners guide for more information about the services OnStar provides.

dimming feature and/or (On/Off): Press to turn the dimming feature and/or compass display on or off.

Cleaning the Mirror

Do not spray glass cleaner directly on the mirror. Use a soft towel dampened with water.
