headlamp PONTIAC BONNEVILLE 2005 User Guide

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
ON or until the manual parking lamps are turned off.
Also, it is 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 exterior lamp control.
Exterior Lighting Battery Saver
If the exterior lamp control has been left on, the exterior
lamps will turn off about 10 minutes after the ignition
is turned to OFF and a 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 exterior lamp control to turn the
lamps back on after turning the ignition to OFF and
opening a door. To delay the lamps from turning off, see
“Twilight Sentinel
®,” listed previously.
Instrument Panel Brightness
When it is dark outside, you can brighten or dim your
instrument panel cluster lights using the DIM knob,
located to the left of the steering wheel on the
instrument panel.
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 DIM knob all
the way clockwise to turn the interior courtesy lamps on.

Entry Lighting
If it is dark enough outside and you press the unlock
button on the remote keyless entry transmitter, if
equipped, the interior courtesy lamps will come on and
stay on for about 25 seconds. The lamps will turn
off immediately by pressing the lock button on the
remote keyless entry transmitter, by turning the ignition
key to ON or by activating the power door locks.
If a door is left ajar, your interior lamps will turn off after
10 minutes to save your battery.
Delayed Entry Lighting
When you open the door to enter your vehicle, the
interior lamps will come on if it is dark enough 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. Locking the doors with the power
door lock switch, or with the lock button on the
remote keyless entry transmitter, if equipped, will
override the delayed entry lighting and the lamps will
turn off immediately.
Theater Dimming
This feature allows for a three to ve-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 nd 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.
Perimeter Lighting
When the unlock button on the remote keyless entry
transmitter, if equipped, is pressed, the DRL headlamps,
parking lamps and back-up lamps will turn on if it is
dark enough outside.

Front Reading Lamps
The front reading lamps, located on the headliner, 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 button. Press it again to turn the lamp off.
To avoid draining your vehicle’s battery, be sure to
turn off the reading lamps when leaving your vehicle.
See “Inadvertent Power Battery Saver” later in this
section for more information.
Rear Reading Lamps
The rear reading lamps, located over each rear door,
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 button. Press it again to turn the lamp off.
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, fan on high
speed, heated seats, and engine cooling fans.
If your vehicle’s battery remains in a heavy discharge
condition for a long period of time, the 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 shaded 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.

2. Adjust the seat, if necessary, before setting the
height using the IMAGE switch.
Press and hold the top of the IMAGE switch, raising
the HUD image as far as possible. Then press on
the bottom of the HUD IMAGE switch to move
the image down, so the image is as low as possible,
but in full view.
3. Turn the INTENSITY knob counterclockwise until
the HUD image is no brighter than necessary. To
turn the HUD off, turn the HUD INTENSITY knob 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 INTENSITY knob.
Polarized sunglasses could make the HUD image
harder to see.
Clean the inside of the windshield as needed to remove
any dirt or lm 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 uid
could leak inside the unit.
If you cannot see the HUD image when the ignition is
on, check to see if:
The HUD unit is covered.
The HUD INTENSITY knob is adjusted correctly.
The HUD image is adjusted to the proper height.
A fuse in the fuse panel may have blown. See
Fuses and Circuit Breakers on page 5-111.
If the HUD image is not clear, it could be too bright.
Move the HUD INTENSITY knob counterclockwise. You
may need to clean the windshield and HUD lens.
Your windshield is part of the HUD system. If you ever
have to have a new windshield, be sure to get one
designed for HUD. If you do not, the HUD image may
look blurred and out of focus.

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.
Do not drink and drive.
Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.
Since you cannot 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 are 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
are driving, do not wear sunglasses at night. They
may cut down on glare from headlamps, but they also
make a lot of things invisible.
4-15

You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even several
seconds, for your eyes to re-adjust to the dark. When
you are faced with severe glare, as from a driver
who does not 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 lm caused by dust. Dirty glass makes
lights dazzle and ash 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 is 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
are not even aware of it.Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a wet
road, you cannot stop, accelerate, or turn as well
because your tire-to-road traction is not as good as on
dry roads. And, if your tires do not have much tread
left, you will get even less traction. It is 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 reexes are tuned for driving on dry pavement.
4-16

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,
oor 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 cannot 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 does
not collect there.
Open a window just a little on the side of the
vehicle that is 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.
