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 OnStap System on page 2-45. 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. 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. Automatic Dimming Rearview Mirror with Onstar@and Compass Your vehicle may have an automatic dimming rearview mirror with a compass display. The mirror also contains Onstar@controls. For more information see OnStap System on page 2-45. The automatic dimming feature functions the same as that of the automatic dimming rearview mirror without a compass. See Automatic Dimming Rearview Mirror with OnStap on page 2-40. 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. Mirror Operation 6 (On/Off): This is the on/off button, located on the lower left side of the mirror face. To turn the automatic dimming feature on or off, press the on/off button. The indicator light will be illuminated when the automatic dimming feature is on. 2-40
