2001 BUICK CENTURY headlamp

2-46 Battery Rundown Protection
Your vehicle has a feature to help prevent you from
draining the battery in case you accidentally leave the
interior courtesy lamps, reading/map lamps, visor
vanity lamps, trunk lamp, underhood lamp or glove box
lamps on. If you leave any of these lamps on, they will
automatically turn off after 20 minutes, if the ignition is
in OFF. The lamps won't come back on again until you
do one of the following:

Turn the ignition on,

turn the lamp switch off, then on, or

open a door.
If your vehicle has less than 15 miles (25 km) on the
odometer, the battery saver will turn off the lamps after
only three minutes.
Retained Accessory Power (If Equipped)
With retained accessory power, your power windows,
audio system and sunroof (if equipped) will continue to
work up to 10 minutes after the ignition key is turned
to OFF and before any of the doors are opened.
Mirrors
Adjust all the mirrors so you can see clearly when you
are sitting in a comfortable driving position.
Inside Day/Night Rearview Mirror
To reduce glare from headlamps behind you, pull the
lever at the bottom of the mirror toward you (to the
night position). To return the mirror to the day position,
push the lever away from you.
Inside Day/Night Rearview Mirror with
OnStar and Map Lamps (If Equipped)
This mirror has a lever located at the bottom of the
mirror between the two map lamps. This lever is used to
change the mirror from day to night position. To reduce
glare from headlamps behind you while driving at night,
turn the lever 90 degrees. To return the mirror to the day
position, return the lever to its original position.

2-47
There are two map lamps located on the bottom of the
mirror. Each lamp is turned on and off by pressing the
button next to the lamp.
There are also three OnStar buttons located at the
bottom of the mirror face. See your dealer for more
information on the system and how to subscribe to
OnStar. See ªOnStar Systemº in the Index for
more information about the services OnStar provides.
Electrochromic Automatic Dimming
Rearview Mirror (If Equipped)
Your vehicle may have an electrochromic day/night
rearview mirror. Push the button in the center of the
mirror to turn this feature on. The mirror will darken
gradually to reduce glare from headlamps behind you.
This may take a few moments.
The mirror's two outer buttons operate the lights on
the bottom sides of the mirror.

2-48
One photocell on the front of the mirror senses when
it is becoming dark outside. Another photocell, facing
rearward, senses headlamps behind you. To turn the
electrochromic feature off, press the button in the
center of the mirror again.
To keep the photocells operating well, occasionally
clean them with a cotton swab and glass cleaner.
Electrochromic Day/Night Rearview
Mirror with OnStar
and Map Lamps
(If Equipped)
Your vehicle may have an automatic electrochromic
day/night rearview mirror with the OnStar System.
The automatic dimming feature is turned on or off by
pressing the far left button, located on the lower part of
the mirror face, for up to three seconds. When turned on,
this mirror functions exactly like the electrochromic mirror
described previously. See ªMirrors, Electrochromic
Day/Night Rearviewº in the Index for more information.There are two map lamps located on the bottom of the
mirror. Each lamp is turned on and off by pressing the
button next to the lamp.There are also three OnStar buttons located at the
bottom of the mirror face. See your dealer for more
information on the system and how to subscribe to
OnStar. See ªOnStar

more information about the services OnStar provides.

2-50 Automatic Dimming/Heated Outside
Rearview Mirror (If Equipped)
With this feature, the driver's side outside mirror
will adjust for the glare of headlamps behind you.
This feature is controlled by the on and off settings
on the electrochromic automatic dimming rearview
mirror. (See ªElectrochromic Automatic Dimming
Rearview Mirrorº earlier in this section.)
The left and right outside mirrors are also heated when
you activate the rear window defogger. (See ªRear
Window Defoggerº in the Index.)
Both outside mirrors can be folded forward or rearward.
This feature is particularly useful in automatic car washes.

Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to be
impaired
-- by alcohol or drugs, with night vision
problems, or by fatigue.Here are some tips on night driving.

Drive defensively.

Don't drink and drive.

Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.

Since you can't see as well, you may need to
slow down and keep more space between you and
other vehicles.

Slow down, especially on higher speed roads. Your
headlamps can light up only so much road ahead.

In remote areas, watch for animals.

If you're tired, pull off the road in a safe place
and rest.
No one can see as well at night as in the daytime. But as
we get older these differences increase. A 50
-year-old
driver may require at least twice as much light to see the
same thing at night as a 20
-year-old.
What you do in the daytime can also affect your night
vision. For example, if you spend the day in bright
sunshine you are wise to wear sunglasses. Your eyes
will have less trouble adjusting to night. But if you're
driving, don't wear sunglasses at night. They may cut
down on glare from headlamps, but they also make a lot
of things invisible.

4-17
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even several
seconds, for your eyes to readjust to the dark. When
you are faced with severe glare (as from a driver who
doesn't lower the high beams, or a vehicle with misaimed
headlamps), slow down a little. Avoid staring directly
into the approaching headlamps.
Keep your windshield and all the glass on your vehicle
clean
-- inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a film caused by dust. Dirty glass makes
lights dazzle and flash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it's easier to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim, so should your eyes
be examined regularly. Some drivers suffer from night
blindness
-- the inability to see in dim light -- and
aren't even aware of it.
Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a wet
road, you can't stop, accelerate or turn as well because
your tire
-to-road traction isn't as good as on dry roads.
And, if your tires don't have much tread left, you'll get
even less traction. It's always wise to go slower and be
cautious if rain starts to fall while you are driving.
The surface may get wet suddenly when your reflexes
are tuned for driving on dry pavement.

4-29

Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags, floor
mats
-- anything you can wrap around yourself or
tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
CAUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can't see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will help
keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well
-charged battery
to restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.
