Automatic
Mirror
(Option)
Your Buick may have the 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,jt holds that position until glare is no
longer present.
d
Time Delay
The mirror delays before switchingcfrom the night back
to the day position. This delay prevents rapid changing
of the mirror as you drive under li-ghts and through
traffic.
Reverse Gear Day Mode
The-reverse mode is another important €eature of the
automatic mirror. When the shift lever
is
placed in
"R'
(Reverse), the mirror shifts to the day mode. This gives
you a bright image in the mirror as you back up.
Automatic/Off Switch
Push the switch up for the AUTO position. The switch
cap will light indicating the mirror will automatically
adjust for glare.
To turn the automatic adjust off, push the switch down.
Front Reading Lights
There are two reading lights located on .the rearview
mirror. Push the switch closest'to the light to turn it on
or off.
