Mirrors Manual Rearview Mirror While sitting in a comfortable driving position, adjust the mirror so you can see clearly behind your vehicle. Hold the mirror in the center to move it up or down and side to side. The day/night control at the bottom of the mirror lets you adjust the mirror to avoid glare from the lamps behind you. Turn the control to the right for nighttime conditions and to the center for daytime conditions. 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 126 for more information about the services OnStar® provides. Automatic Dimming Rearview Mirror While sitting in a comfortable driving position, adjust the mirror so you can see clearly behind your vehicle. Hold the mirror in the center to move it up or down and side to side. The vehicle may have an automatic dimming rearview mirror that darkens gradually to reduce the glare of headlamps from behind. Press the button in the center of the mirror to turn this feature on or off. One photocell on the front of the mirror senses when it is becoming dark outside. Another photocell, facing rearward, senses headlamps behind you. To keep the photocells operating well, occasionally clean them with a cotton swab and glass cleaner.
