Automatic Inside Mirror
Your Buick may have an automatic inside mirror.
The automatic mirror adjusts for the glare of headlights
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.
Automatic Mirror Settings
There is an automatic and an off position. When the
button on the bottom of the mirror is pressed up and has
a green halo, the mirror is on automatic. Press again to
turn off.
Time Delay
The mirror delays before changing from the night to the
day position. This delay prevents rapid changing of the
mirror as you drive under lights and through traffic.
Reverse Gear Day Mode
The reverse mode is another important feature of the
automatic mirror. When the shift lever is placed in "R"
(Reverse), the mirror changes to the day mode. This
gives you a bright image in the mirror as you back up.
