Automatic Dimming Rearview Mirror with OnStar® Your vehicle may have an automatic dimming rearview mirror with the OnStar® System. The automatic dimming feature is automatically on or enabled each time the vehicle is started. If you need to turn off the feature, press the button located below the mirror, on the far left, once and the green indicator light will go out indicating the feature is off. To turn the feature back on, press and release the button again and the green indicator light will come on. While turned on, this mirror functions exactly like the automatic dimming mirror described previously. There are also three OnStar® buttons located at the bottom of the mirror. See your dealer for more information on the system and how to subscribe to OnStar®. See OnStar® System on page 2-38 for more information about the service OnStar® provides. 2-36
