Electrochromic DaylNight Rearview Mirror Press the button at the base of the mirror to turn on the automatic feature. The button has an indicator light to (Option) show it is on. Press the button again to turn the automatic feature off. Time Delay The automatic mirror has a time delay feature which prevents unnecessary switching from the night back to the day position. This delay prevents rapid changing of the mirror as you drive under lights and through traffic. Your Pontiac may have an automatic electrochromic dayjnight rearview mirror. This mirror automatically changes to reduce glare from headlamps behind you. A photocell on the back of the mirror senses when it is becoming dark outside. Another photocell built into the mirror surface senses when headlamps are behind you. At night, when the glare is too high, the mirror will gradually darken to reduce glare (this change may take a few seconds). The mirror will return to its clear daytime state when the glare is reduced. Reverse Gear Day Mode The reverse day mode is another important feature of the electrochromic mirror. When you shift into REVERSE (R), the mirror changes to the day mode. This gives you a bright image in the mirror as you back up. Cleaning the Photocells Use a cotton swab and glass cleaner to clean the photocells when necessary. Manual Remote Control Mirror The outside rearview mirror should be adjusted so you can justsee the side of your vehicle when you are sitting in a comfortable driving position. 2-49
