Mirrors Automatic Dimming Rearview Mirror with OnStar® The vehicle may have an automatic dimming inside rearview mirror with OnStar® controls. For more information about OnStar®, see OnStar® System on page 137. Passenger Airbag Indicator The mirror may have a passenger airbag indicator on the mirror glass, just above the buttons. If the vehicle has this feature, the mirror will display the word ON, or an airbag symbol in Canada, when the passenger airbag is enabled. See Passenger Sensing System on page 79 for more information. 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. O (On/Off): The on/off button, located on the lower left side of the mirror, is used for the automatic dimming functions of the rearview mirror. Mirror Operation The automatic dimming feature comes on each time the vehicle is started. Automatic dimming reduces the glare of lights from behind the vehicle. To turn the automatic dimming feature on or off, press and release the on/off button. The indicator light will come on when this feature is on. 132
