The vehicle may have an automatic dimming inside rearview mirror with a compass display and/or map lamps, and OnStar®. If the vehicle has OnStar, there are three control buttons located at the bottom of the mirror. See OnStar® System for more information on the services OnStar® provides.

Automatic Dimming Mirror Operation

The mirror automatically changes to reduce glare from headlamps behind you. A time delay feature prevents rapid changing from the day to night positions while driving under lights and through traffic.

(On/Off): The automatic dimming feature is activated when the vehicle is started. Press and hold this button for up to six seconds to turn this feature on or off.

(Indicator Light): This light turns on when the automatic dimming feature is active.

Map Lamps

If the mirror has map lamps, they are located at the bottom of the mirror. To manually turn the lamps on or off, press the button next to each lamp.

Cleaning the Mirror

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