from only a few seconds to three minutes. Your

“dark” and your lights will come on.

-Headlights Reminder Light (Canada Only)
If your vehicle was first sold, when new, in Canada, this
light will go on at night to remind you to turn on the
headlights.
Daytime Running Lights (Canada Only)
The Canadian Federal Government has decided that
“Daytime Running Lights” (DRL) are a useful feature,
in that DRL can make your vehicle more visible to
pedestrians and other drivers during daylight hours.
DRL are required on new vehicles sold in Canada. Your
DRL work with a light sensor on
top of the
instrument panel. Don’t cover it up.
The low beam headlights will come
on at reduced
brightness in daylight when:
The ignition is on.
The headlight switch is off, and
The transaxle is not in “P” (Park).
At dusk, if the Twilight Sentinel feature is turned
on, the
exterior lights will come on automatically and the low
beams will change to
full brightness. At dawn, the
exterior lights will
go out and the low beams will
change to the reduced brightness of DRL (if the
headlight switch is
off). If the Twilight Sentinel is off, at
dusk a “HEADLIGHTS SUGGESTED” message will
appear on the instrument panel to remind you to turn. on
the headlights.
Of course, you may still turn on the headlights any time
you need to.
.
To idle your vehicle with the DRL off, shift the
transaxle into
T“ (Park). The DRL will stay off until
you shift out of “P”.(Park).

Mirrors

Automatic (Option) Settings
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 operatiol-~
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.
MIN: The minimum setting is suggested when driving
where glare conditions change
often. '"in" works well
for city driving at night.
MAX: Maximum sensitivity is a good setting for
highway driving in light traffic. The mirror
starts to
darken in any glare, such as headlights a long way
behind your car.
OFF: The mirror will stay in the day mode.
Time Delay
The mirror delays before 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.
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 shifts to the day mode. This gives
you a bright image in the mirror as you back up.
