Electrochromic Day/Night Rearview Mirror (If Equipped) Your vehicle may have an automatic electrochromic day/night rearview mirror. Your vehicle's mirror may also contain OnStarR controls. This is the on/off button for mirrors equipped with OnStar controls. When this 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 high, 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 To turn on the automatic dimming feature, press AUTO (or the on/off button for mirrors equipped with OnStar controls). To turn off automatic dimming, press OFF (or the on/off button for mirrors equipped with OnStar controls). The indicator light will be illuminated when this feature is active. Electrochromic Day/Night Rearview Mirror with Compass (If Equipped) Your vehicle may have an electrochromic inside rearview mirror with a compass. Your vehicle's mirror may also contain OnStarR controls. This is the on/off button for mirrors equipped with OnStar controls. Pressing the MIRROR button (or the on/off button for mirrors equipped with OnStar controls) located at the bottom of the mirror, turns the automatic dimming feature on or off. The mirror also includes an eight-point compass display in the upper right corner of the mirror face. When on, the compass automatically calibrates as the vehicle is driven. 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. 2-51
