light CHEVROLET AVEO 2004 1.G Service Manual

If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
•Reducing vehicle speed.
•Avoiding hard accelerations.
•Avoiding steep uphill grades.
If the light stops flashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to flash, when it is safe to do so,
stop the vehicle.Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart
the engine. If the light remains on steady, see “If the
Light Is On Steady” following. If the light is still flashing,
follow the previous steps, and see your dealer for
service as soon as possible.
If the Light Is On Steady
You also may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. SeeFilling Your Tank on page 5-8. The
diagnostic system can determine if the fuel cap has
been left off or improperly installed. A loose or missing
fuel cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.
3-30

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 5-5. Poor fuel quality will
cause your engine not to run as efficiently as designed.
You may notice this as stalling after start-up, stalling
when you put the vehicle into gear, misfiring, hesitation
on acceleration or stumbling on acceleration.
(These conditions may go away once the engine is
warmed up.) This will be detected by the system and
cause the light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
your dealer can check the vehicle. Your dealer has
the proper test equipment and diagnostic tools to fix
any mechanical or electrical problems that may
have developed.Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the
Check Engine light is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen
if you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.

Oil Pressure Light
If you have a low engine
oil pressure problem, this
light will stay on after
you start your engine, or
come on when you
are driving. This indicates
that your engine is not
receiving enough oil.
The engine could be low on oil, or could have some
other oil problem. Have it fixed immediately.
The oil light could also come on in three other situations:
•When the ignition is on but the engine is not
running, the light will come on as a test to show you
it is working. The light will go out when you turn
the ignition on. If it does not come on with the
ignition on, you may have a problem with the fuse
or bulb. Have it fixed right away.
•If you are idling at a stop sign, the light may blink
on and then off.
•If you make a hard stop, the light may come on for
a moment. This is normal.
{CAUTION:
Do not keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would not be
covered by your warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.
Fog Lamp Light
If your vehicle has this
feature, the fog lamps light
will come on when the
fog lamps are in use.
The light will go out when the fog lamps are turned off.
See “Fog Lamps” underExterior Lamps on page 3-8
for more information.
3-32

Daytime Running Lamps Indicator
Light
This light will come on
when the Daytime Running
Lamps (DRL) are on.
A flashing DRL light indicates a possible burned out
headlamp, or that the vehicle may need service to repair
a defective DRL relay.
See “Daytime Running Lamps (DRL)” underExterior
Lamps on page 3-8for further information on the
DRL system.
Door Ajar Light
When the ignition is on,
this light will stay on until
all doors are closed
and completely latched.
If the key is in the ignition while the driver’s door is
open, you will also hear a warning chime.
3-33

Theft-Deterrent Feature
The theft-deterrent system is designed to discourage
theft of your radio. When the radio and vehicle are
turned off, your radio has a blinking red light to indicate
that the theft-deterrent system is activated.
The theft-deterrent system also activates when the
audio system has been disconnected from the battery.
When this occurs, the AF code and security code
will have to be entered in order to operate your radio.
An identification card stamped with the AF code
and security code will be provided with the vehicle.
Keep it in a safe place, not in the vehicle.
To enter the security code do the following:
1. Turn the ignition to ACC or ON.
2. Turn the radio on. AF or COdE will flash on the
display. If AF flashes on the display, go to Step 2.
If COdE flashes on the display, go to Step 4.
3. Enter the AF code by using the preset pushbuttons.
COdE will flash on the display.
4. Enter the security code by using the preset
pushbuttons. When the complete security code is
entered, the code will flash three times.If the security code is not entered correctly, Err will
appear on the display for a few seconds. When
COdE appears back on the display, repeat Step 4.
If the incorrect AF code is entered, an incorrect
frequency level may be chosen and the radio
reception may be affected. If this occurs, reset the
audio system by removing and re-installing the
AUDIO fuse. See “Instrument Panel Fuse Block”
underFuses and Circuit Breakers on page 5-85for
more information. Then repeat Steps 1 through 4.
Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines.
Try reducing the treble to reduce this noise.
FM
FM stereo will give you the best sound, but FM signals
will reach only about 10 to 40 miles (16 to 65 km).
Tall buildings or hills can interfere with FM signals,
causing the sound to come and go.
3-43

Care of Your CDs
Handle CDs carefully. Store them in their original cases
or other protective cases and away from direct
sunlight and dust. If the surface of a CD is soiled,
dampen a clean, soft cloth in a mild, neutral detergent
solution and clean it, wiping from the center to the edge.
Be sure never to touch the side without writing when
handling CDs. Pick up CDs by grasping the outer edges
or the edge of the hole and the outer edge.
Care of Your CD Player
The use of CD lens cleaners for CD players is not
advised, due to the risk of contaminating the lens of the
CD optics with lubricants internal to the CD mechanism.
Backglass Antenna
The AM-FM antenna is integrated with the rear window
defogger, located in the rear window. Be sure that the
inside surface of the rear window is not scratched and
that the lines on the glass are not damaged. If the inside
surface is damaged, it could interfere with radio
reception. Also, for proper radio reception, the antenna
connector at the top-center of the rear window needs to
be properly attached to the post on the glass.Notice:Using a razor blade or sharp object to clear
the inside rear window may damage the rear window
antenna and/or the rear window defogger. Repairs
would not be covered by your warranty. Do not clear
the inside rear window with sharp objects.
Notice:Do not apply aftermarket glass tinting with
metallic lm. The metallic lm in some tinting
materials will interfere with or distort the incoming
radio reception. Any damage caused to your
backglass antenna due to metallic tinting materials
will not be covered by your warranty.
Because this antenna is built into your rear window,
there is a reduced risk of damage caused by car washes
and vandals.
If you choose to add a cellular telephone to your
vehicle, and the antenna needs to be attached to the
glass, be sure that you do not damage the grid lines for
the AM-FM antenna. There is enough space between
the lines to attach a cellular telephone antenna
without interfering with radio reception.
Do not apply aftermarket glass tinting to the back glass.
The metallic film in some tinting materials will interfere
with or distort the incoming radio reception. Care
must be taken when cleaning the rear window because
it breaks in the resistive material heating element
and will adversely affect radio and defogger
performance. See your dealer for details.
3-44

Avoid needless heavy braking. Some people drive
in spurts−heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is
a mistake. Your brakes may not have time to cool
between hard stops. Your brakes will wear out much
faster if you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you will eliminate a lot of unnecessary braking.
That means better braking and longer brake life.
If your engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do,
the pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and
the brake pedal will be harder to push.Anti-lock Brake System (ABS)
Your vehicle may have anti-lock brakes. ABS is an
advanced electronic braking system that will help
prevent a braking skid.
If your vehicle has anti-lock
brakes, this warning light
on the instrument panel will
come on briefly when
you start your vehicle.
4-7

Remember: Anti-lock does not change the time you
need to get your foot up to the brake pedal or always
decrease stopping distance. If you get too close to
the vehicle in front of you, you will not have time to apply
your brakes if that vehicle suddenly slows or stops.
Always leave enough room up ahead to stop, even
though you have anti-lock brakes.
Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down firmly and let anti-lock work for you. You may feel
a slight brake pedal pulsation or notice some noise,
but this is normal.
Braking in Emergencies
At some time, nearly every driver gets into a situation
that requires hard braking.
If you have anti-lock, you can steer and brake at the
same time. However, if you do not have anti-lock, your
first reaction — to hit the brake pedal hard and hold
it down — may be the wrong thing to do. Your wheelscan stop rolling. Once they do, the vehicle can not
respond to your steering. Momentum will carry it
in whatever direction it was headed when the wheels
stopped rolling. That could be off the road, into the very
thing you were trying to avoid, or into traffic.
If you do not have anti-lock, use a “squeeze” braking
technique. This will give you maximum braking
while maintaining steering control. You can do this by
pushing on the brake pedal with steadily increasing
pressure.
In an emergency, you will probably want to squeeze the
brakes hard without locking the wheels. If you hear or
feel the wheels sliding, ease off the brake pedal.
This will help you retain steering control. If youdohave
anti-lock, it is different. See “Anti-Lock Brake System”
in this section.
In many emergencies, steering can help you more than
even the very best braking.
4-9

Off-Road Recovery
You may find that your right wheels have dropped off the
edge of a road onto the shoulder while you’re driving.
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease off the
accelerator and then, if there is nothing in the way,
steer so that your vehicle straddles the edge of
the pavement. You can turn the steering wheel up to
one-quarter turn until the right front tire contacts
the pavement edge. Then turn your steering wheel
to go straight down the roadway.
Passing
The driver of a vehicle about to pass another on a
two-lane highway waits for just the right moment,
accelerates, moves around the vehicle ahead, then
goes back into the right lane again. A simple maneuver?
Not necessarily! Passing another vehicle on a two-lane
highway is a potentially dangerous move, since the
passing vehicle occupies the same lane as oncoming
traffic for several seconds. A miscalculation, an error in
judgment, or a brief surrender to frustration or anger
can suddenly put the passing driver face to face with the
worst of all traffic accidents — the head-on collision.
So here are some tips for passing:
•“Drive ahead.” Look down the road, to the sides
and to crossroads for situations that might affect
your passing patterns. If you have any doubt
whatsoever about making a successful pass, wait
for a better time.
•Watch for traffic signs, pavement markings and
lines. If you can see a sign up ahead that might
indicate a turn or an intersection, delay your pass.
A broken center line usually indicates it is all
right to pass (providing the road ahead is clear).
Never cross a solid line on your side of the lane or
a double solid line, even if the road seems empty
of approaching traffic.
4-12

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 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.
