2000 PONTIAC BONNEVILLE headlamp

2-43
At night, you can turn off all exterior lamps when you
are in PARK (P) by turning the Twilight Sentinel knob
all the way to OFF. If the knob was already in OFF, it
must be cycled to ON then back to OFF, to turn the
exterior lighting off. The lamps will come back on when
you turn the knob clockwise.
If the Twilight Sentinel lighting is active, it can be
disabled by turning on the manual parking lamps. This
lighting will be disabled until the key is turned from
RUN or until the manual park lamps are turned OFF.
Also, it's possible that your headlamps may go out if
you drive from a dark area into a bright area like a
lighted parking lot. If this happens, turn on your
headlamps with the regular headlamp switch.
Exterior Lighting Battery Saver
If the manual lamp control has been left on, the exterior
lamps will turn off approximately 10 minutes after the
ignition is turned to OFF and any door has been opened.
This protects against draining the battery in case you
have accidentally left the headlamps or parking lamps
on. If you need to leave the lamps on for more than
10 minutes, use the manual control to turn the lamps
back on after turning the ignition to OFF and opening
any door. To delay the lamps from turning off,
see ªTwilight Sentinel

º in the Index.
Interior Lamps
Instrument Panel/Brightness Control
When it is dark outside, you can brighten or dim your
instrument panel cluster lights by turning the DIM knob in
the light control. Turn the knob clockwise to brighten the
instrument panel cluster lights and displays. Turn the knob
clockwise all the way to turn on the interior courtesy lamps.
Turn the knob counterclockwise to dim the instrument panel
cluster lights and displays and to turn off the courtesy lamps.
Courtesy Lamps
If it is dark enough outside, when any door is opened,
several lamps will come on. They make it easier for you
to enter and leave the vehicle. Turn the dimmer knob all
the way clockwise to turn the interior courtesy lamps on.
Illuminated Entry
If it is dark enough outside and you press the button with
the unlock symbol on the remote keyless entry transmitter,
the interior courtesy lamps will come on and stay on for
approximately 40 seconds. The lamps will turn off
immediately by pressing the button with the lock symbol
on the remote keyless entry transmitter, turning the ignition
key to RUN or activating the power door locks.
If a door is left ajar, your interior lamps will turn off
after 10 minutes to save your battery.

2-44
Delayed Entry Lighting
When you open the door to enter your vehicle, the
interior lamps will come on if it is dark outside. When
you close the door with the ignition off, the interior
lamps will stay on for 25 seconds or until the ignition is
turned on. Please note that locking the doors with the
power door lock switch, or with the lock button on the
remote keyless entry transmitter, will override the
delayed entry lighting and the lamps will turn
off immediately.
Theater Dimming
This feature allows for a three to five-second fade out of
the courtesy lamps instead of immediate turn off after
you remove the key from the ignition.
Delayed Exit Lighting
This feature will turn on the interior lamps for
25 seconds after you remove the key from the ignition
while the doors are closed and it is night. This will give
you time to find the door handle or lock switches as
you exit the vehicle.
This lighting will only be deactivated if the key is
reinserted into the ignition switch or the power door
locks are activated.
Parade Dimming
To activate the instrument panel backlighting during the
day, turn the headlamp switch to the parking lamp or
headlamp position. Dimming of the instrument panel
display is not possible during daylight hours. The
instrument panel display can only be adjusted when the
parking lamps or headlamps are on and it is dark outside.
Perimeter Lighting
When the button with the unlock symbol on the remote
keyless entry transmitter is pressed, the DRL headlamps,
parking lamps and back
-up lamps will turn on if it is
dark enough outside.
Personalization Programming
This feature can be programmed in the on or off mode for
each transmitter. Vehicles are delivered with this feature on.
To turn the feature off:
1. Keep all doors closed, vehicle in PARK (P) and the
ignition on throughout this procedure.
2. Press and hold LOCK on the power door lock switch
throughout this procedure. All the doors will lock.
3. Press the instant alarm on the transmitter. Perimeter
lighting remains on at this time and the horn will
chirp twice.

2-46
Rear Reading Lamps
The rear reading lamps will come on as courtesy lamps
when you open any of the doors while it is dark outside.
They will also come on as part of the interior lighting
features listed previously.
To turn on a reading lamp when the doors are closed,
press either switch. Press it again to turn the lamp off.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle's battery
against drainage from the interior lamps, trunk lamp,
glove box lamp or cigarette lighters. When the ignition
is turned off, the power to these features will
automatically turn off after 10 minutes. Power will be
restored for an additional 10 minutes if any door is
opened, the trunk is opened or the courtesy lamp switch
is turned on. To restore power back to the cigarette
lighters the ignition must be turned back to RUN.
Battery Load Management
The battery load management feature is designed to
monitor the vehicle's electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at
higher revolutions per minute (rpm) than normal to
make sure the battery charges. High electrical loads may
occur when several of the following are on: headlamps,
high beams, fog lamps, rear window defogger, high
blower fan, heated seats and engine cooling fans.

2-47
If your vehicle's battery remains in a heavy discharge
condition for a long period of time, the blower fan, rear
defogger, heated seats and heated mirrors will be
disabled and the DIC will display BATTERY SAVER
ACTIVE. This can happen either under long periods of
idling or low speed driving with high electrical loading,
or in the event of a charging system fault.
Monitor the battery voltage when in the BATTERY
SAVER ACTIVE mode.

If the voltmeter remains in the red area (below
11 volts) when driving then have the charging
system serviced immediately.

If the voltage increases above 12 volts then the battery
needs to be recharged. Try driving on the highway
with as few electrical accessories on as possible.
Mirrors
Inside Day/Night Manual Rearview Mirror
When you are sitting in a comfortable driving position,
adjust the mirror so you can see clearly behind your
vehicle. 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 lamps
behind you. Push the tab away from you for daytime
use; pull it toward you for night use.
Electrochromic Day/Night Rearview Mirror
(If Equipped)
Your vehicle may have an automatic electrochromic
day/night rearview mirror.
When this feature is turned on, the mirror automatically
changes to reduce glare from headlamps behind you.
A photocell on the mirror senses when it is becoming
dark outside. Another photocell built into the mirror face
senses when headlamps are behind you.
At night, when the glare is too high, the mirror will
gradually darken to reduce glare (this change may take a
few seconds). The mirror will return to its clear daytime
state when the glare is reduced.

2-81
The HUD controls are located to the left of the
steering column.
1. Start your engine and turn the HUD dimmer all of
the way clockwise.
The brightness of the HUD image is determined by
ambient light, and where you have set the HUD
dimmer control.2. Adjust the seat, if necessary, before setting the
height control.
Press and hold the top of the IMAGE (image height)
control, raising the HUD image as far as possible.
Then press on the bottom of the HUD image height
control to move the image down, so the image is as
low as possible, but in full view.
3. Turn the dimmer control counterclockwise until the
HUD image is no brighter than necessary. To turn the
HUD off, rotate the HUD dimmer control all the
way counterclockwise.
If the sun comes out, or it becomes cloudy, or if you turn
on your headlamps, you may need to adjust the HUD
brightness using the HUD dimmer control. Polarized
sunglasses could make the HUD image harder to see.
Clean the inside of the windshield as needed to remove
any dirt or film that reduces the sharpness or clarity of
the HUD image.
Spray household glass cleaner on a soft, clean cloth.
Wipe the HUD lens gently, then dry it. Do not spray
cleaner directly on the lens, because the cleaner fluid
could leak inside the unit.

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.

Tie a red cloth to your vehicle to alert police that
you've been stopped by the snow.

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.
