Automatic Dimming Rearview Mirror with OnStar® for Cadillac STS 2008

Your vehicle may have an automatic dimming rearview mirror that also contains OnStar® controls. For more information on OnStar®, see OnStar® System .

Mirror Operation

(On/Off): Press and hold the button, located on the lower left side of the mirror face, for about three seconds to turn the automatic dimming feature on or off. The indicator light will illuminate when this feature is active. The automatic dimming feature is active each time the vehicle is started.

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.
