Mirrors Automatic Dimming Rearview Mirror 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 on page 2-41 for more information on the services OnStar® provides. 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. 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. Compass Compass Operation With the compass feature on, each time the vehicle is started, the compass will take a few seconds to adjust and display the current compass heading. For example, NE is displayed for north-east. P (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. T (Indicator Light): This light turns on when the automatic dimming feature is active. 2-38
