Mirrors Manual Inside Mirror When you are sitting in a comfortable driving position, adjust the mirror so you can see clearly behind your car. Grip the mirror in the center to move it up or down and side to side. The day-night adjustment allows you to adjust the mirror to avoid glare from the lights behind you. Pull the tab forward for daytime use; push it back for night use. Automatic Inside Mirror (Option) Your Buick may have an automatic inside mirror. The automatic mirror adjusts for the glare of headlamps behind you. It detects changes in light, and then adjusts for day or night operation. During the day the mirror reflects all the light from behind your car. At night, when the glare is too high, it changes to the night mode. Then, it reflects only part of the light from behind you. When the mirror changes to the night mode, it holds that position until glare is no longer present. 2-43
