headlamp CHEVROLET IMPALA 2004 8.G User Guide

Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may have to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control. Many
drivers nd this to be too much trouble and don’t use
cruise control on steep hills.
Ending Cruise Control
There are three ways to cancel the cruise control:
Step lightly on the brake pedal.
Slide the lever on the multifunction lever to the
OFF position.
Press the COAST and ACCEL buttons at the
same time.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
Exterior Lamps
The exterior lamps control
is located on the
instrument panel to the left
of the steering wheel.
It controls the following systems:
Headlamps
Taillamps
Parking Lamps
License Plate Lamps
Instrument Panel Lights
3-14

The exterior lamps control has three positions:
Off:Push the control all the way in to turn off the
exterior lamps.
Parking Lamps:Pull the control out halfway to turn
on the parking lamps together with the following:
Taillamps
License Plate Lamps
Instrument Panel Lights
Headlamps:Pull the control all the way out to turn on
the headlamps together with the previously listed
lamps and lights. SeeInterior Lamps on page 3-17for
information on the instrument panel brightness
control and on the dome lamps. A warning chime will
sound if you open the driver’s door when the ignition
switch is off and the headlamps are on.
Daytime Running Lamps/Automatic
Headlamp System
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
rst sold in Canada.A light sensor on top of the instrument panel makes
the DRL work, so be sure it isn’t covered.
The DRL system’s automatic headlamp control will
make your high-beam headlamps come on at a reduced
brightness when the following conditions are met:
The ignition is on,
the exterior lamps control is off and
the gearshift is not in PARK (P).
When the DRL are on, only your high-beam headlamps,
at a reduced level of brightness, will be on. The
headlamps, taillamps, sidemarker and other lamps won’t
be on. Your instrument panel and cluster won’t be lit
up either.
When it’s dark enough outside, your high-beam
headlamps will turn off and the headlamps and parking
lamps will turn on. The other lamps that come on
with your headlamps will also come on.
When it’s bright enough outside, your headlamps will
go off and your DRL will come on.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Delayed Headlamps
The delayed headlamps feature provides a period of
exterior lighting as you leave the area around your
vehicle. The feature is activated when the headlamps
are on due to the automatic headlamps control
feature described previously in this section, and when
the ignition is turned off. Your headlamps will then
remain on until the exterior lamps control is moved to
the parking lamps position or until either a 30 second or
60 second lighting period has ended.
If you turn off the ignition with the headlamps switch in
the parking lamps or headlamps position, the delayed
headlamps cycle will not occur.
To disable the delayed headlamps feature or change
the time of delay, seeVehicle Customization Settings on
page 3-97.
Fog Lamps
If your vehicle is equipped
with fog lamps, the button
is located on the
instrument panel next to
the exterior lamps
control wheel to the left of
the steering column.
Your ignition must be in ON for the fog lamps to
illuminate.
To turn the fog lamps on, press the FOG button. A light
will come on in the button to let you know that the
fog lamps are on. Press the FOG button again to turn
the fog lamps off.
The ignition must be ON and the parking lamps must be
on for your fog lamps to work.
The fog lamps will go off while you change to high-beam
headlamps.
3-16

Delayed Exit Lighting
This feature illuminates the interior for a period of time
after the key is removed from the ignition.
The ignition must be off for delayed exit lighting to work.
When the key is removed, interior illumination will
activate and remain on until one of the following occurs:
The ignition is moved to ON,
the power door locks are activated, or
an illumination period of 25 seconds has elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled and the
interior lamps will remain on because a door is open.
Parade Dimming
The instrument panel has an added feature called
parade mode. This feature prohibits the dimming of your
instrument panel displays during the daylight while
the headlamps are on so that you’ll still be able to see
the displays.
Reading Lamps
Your vehicle may be equipped with reading lamps that
are located on the assist handles in the headliner.
These lamps and the interior courtesy lamps come on
when any door is opened. Press the lens to turn them on
and off.
Dome Lamp
If your vehicle has this feature, the dome lamp will
come on when you open a door. You can also turn this
lamp on by turning the exterior lamps control clockwise
as far as it will go. Vehicles that have the optional
sunroof do not have a dome lamp.
Battery Rundown Protection
Your vehicle has a feature to help prevent you from
draining the battery in case you accidentally leave on the
interior courtesy lamps, reading/map lamps, visor
vanity lamps or trunk lamp. If you leave any of these
lamps on, they will automatically turn off after
10 minutes, if the ignition is off. The lamps won’t come
back on again until you do the following:
Turn the ignition on, or
turn the exterior lamps control off, then on again.
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.
Battery rundown protection will also work if the
headlamps are left on. After having been left on for
10 minutes, the headlamps and the parking lamps will
ash three times. They will remain on for one more
minute before turning off automatically.

Highbeam Out Warning Message
If this message appears, you may have a problem with
your high-beam headlamps.
The message will stay on about 60 seconds. When the
ignition is turned off, this message will be displayed
again for three seconds to remind you that you
may have a problem with your highbeam-headlamps.
Be sure to check your bulbs right away and replace
them if necessary.
SeeBulb Replacement on page 5-58.
Driver Information Center (DIC)
If your vehicle is equipped with the DIC, it will show
information about the vehicle and the surroundings. It is
located in the headliner between the sun visors. United States

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 can not 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.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 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.

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.
Then, shut the engine off and close the window almost all
the way to preserve the heat. Start the engine again and
repeat this only when you feel really uncomfortable from
the cold. But do it as little as possible. Preserve the fuel
as long as you can. To help keep warm, you can get out
of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
If You Are Stuck: In Sand, Mud, Ice
or Snow
In order to free your vehicle when it is stuck, you will
need to spin the wheels, but you do not want to
spin your wheels too fast. The method known as
“rocking” can help you get out when you are stuck, but
you must use caution.
{CAUTION:
If you let your tires spin at high speed, they can
explode, and you or others could be injured.
And, the transaxle or other parts of the vehicle
can overheat. That could cause an engine
compartment re or other damage. When you
are stuck, spin the wheels as little as possible.
Do not spin the wheels above 35 mph (55 km/h)
as shown on the speedometer.
Notice:Spinning your wheels can destroy parts of
your vehicle as well as the tires. If you spin the
wheels too fast while shifting your transaxle back
and forth, you can destroy your transaxle. See
“Rocking Your Vehicle To Get It Out.”
For information about using tire chains on your vehicle,
seeTire Chains on page 5-80.

Headlamp Aiming
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the low beam
may be necessary if it is difficult to see lane markers
(for horizontal aim), or if oncoming drivers ash
their high beams at you (for vertical aim). If you believe
your headlamps need to be re-aimed, we recommend
that you take your vehicle to the dealer for service.
However, it is possible for you to re-aim your headlamps
by following the procedure in the service manual for
your vehicle.
Notice:To make sure your headlamps are aimed
properly, read all the instructions before beginning.
Failure to follow these instructions could cause
damage to headlamp parts.
Bulb Replacement
For the proper type of replacement bulb, see
Replacement Bulbs on page 5-62.
For any bulb changing procedure not listed in this
section, contact your dealer.
Halogen Bulbs
{CAUTION:
Halogen bulbs have pressurized gas inside and
can burst if you drop or scratch the bulb. You or
others could be injured. Be sure to read and
follow the instructions on the bulb package.
