Mirrors Automatic Dimming Rearview Mirror with OnStar® Your vehicle may have an automatic dimming rearview mirror with OnStar® system controls. For more information about OnStar®, see OnStar® System on page 2-42. When the automatic dimming feature is turned on, the mirror automatically changes to reduce glare from headlamps behind you. A photocell on the mirror senses when it is becoming dark outside. Another photocell built into the mirror face senses when headlamps are behind you. At night, when the glare is too bright, the mirror will gradually darken to reduce glare. This change may take a few seconds. The mirror will return to its clear, daytime state when the glare is reduced. Mirror Operation O (On/Off): Press the on/off button, located on the lower left side of the mirror face, to turn the automatic dimming feature on or off. The indicator light will be illuminated when the automatic dimming feature is on. Cleaning the Mirror When cleaning the mirror, use a paper towel or similar material dampened with glass cleaner. Do not spray glass cleaner directly on the mirror as that may cause the liquid cleaner to enter the mirror housing. 2-37
