Electrochromic Day/Night Rearview Mirror with Compass, Temperature and OnStarR There are three buttons for the OnStar system. See your dealer for more information on the system and how to subscribe to OnStar. See "OnStarR System" in the Index for more information about the services OnStar provides. Automatic Dimming Feature When turned on, an electrochromic mirror automatically dims to the proper level to minimize glare from any headlamps behind you after dark.

A light on the mirror will be lit when the feature is turned on. It will go out when the feature is turned off. Temperature Display The temperature display is in the window in the upper right corner of the mirror face. The display will show the temperature in F or C when the compass is on. Press the on/off button to cycle through F, C, or OFF. _ _ _ _ This is the on/off button. 2-51
