CHEVROLET AVEO 2002 Service Repair Manual

Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
or moisture condensing on the cool window glass. This
can be minimized if the climate control system is used
properly. There are two modes to clear fog or frost from
your windshield. Use the defog mode to clear the
windows of fog or moisture and warm the passengers.
Use the defrost mode to remove fog or frost from the
windshield more quickly.
For best results, clear all snow and ice from the
windshield before defrosting.
Select one of these available modes from the
right knob.
0(Defog):This mode directs most of the air to the
windshield and the floor outlets. A small amount of air
is also directed to the outboard outlets for the side
windows and to the instrument panel side outlets.
When you select this mode, the system runs the
air-conditioning compressor. To defog the windows
faster, turn the temperature control knob clockwise to
the warmest setting.
1(Defrost):This mode directs the air to the
windshield and the outboard outlets for the side
windows. A small amount of air is also directed to the
instrument panel side outlets. When you select this
mode, the system runs the air-conditioning compressor.
To defrost the windows faster, turn the temperature
control knob clockwise to the warmest setting.
Do not drive the vehicle until all windows are clear.
Rear Window and Outside Mirror
Defogger
Your vehicle may have a rear window and outside
mirror defogger. This feature will only work when the
ignition is turned to ON.
The rear window defogger uses a warming grid to
remove fog or frost from the rear window. Before using
this feature, clear as much snow from the rear
window as possible.
<(Rear Window Defogger):Press this button to
turn the rear window and outside mirror defogger on or
off. An indicator light in the button will come on to let
you know that the feature is activated.
If your vehicle does not have air conditioning, the rear
window defogger will remain on until the button is
pressed again.
3-20

If your vehicle has air conditioning, the rear window
defogger will turn off about 10 minutes after the button
is pressed. The defogger can also be turned off by
pressing the button again or by turning the engine off.
Notice:Do not use anything sharp on the inside of
the rear window. If you do, you could cut or
damage the warming grid, and the repairs would not
be covered by your warranty. Do not attach a
temporary vehicle license, tape, a decal or anything
similar to the defogger grid.
Outlet Adjustment
Use the knob located in the center of each outlet to
change the direction of the airflow.
Operation Tips
•
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into your vehicle.
•Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
•Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
Passenger Compartment Air Filter
Your vehicle may have a passenger compartment
air filter. It is located behind the glove box and can be
accessed after removing the glove box from its housing.
The filter traps most of the pollen from air entering
the module. Like your engine’s air cleaner/filter, it may
need to be changed periodically.
To change the passenger compartment air filter, use the
following steps:
1. Open the glove box halfway down.
2. Grip the glove box by both the upper and lower
sides and pull it out of its housing.
3-21

3. Remove the four screws on the knee bolster. 4. Remove the knee bolster.
5. Then reverse the steps to install the new air filter
and replace the glove box.
View the air flow arrows on the filter before installing
to ensure you install the filter correctly.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the engine
just to let you know they’re working. If you are familiar
with this section, you should not be alarmed when
this happens.Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays on
as you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual’s
advice. Waiting to do repairs can be costly and even
dangerous. So please get to know your warning
lights and gages. They’re a big help.

Instrument Panel Cluster
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You will know how fast
you are going, how much fuel you are using, and many other things you will need to drive safely and economically.
Your vehicle’s instrument panel cluster includes indicator warning lights and gages that are explained on the following
pages.
United States shown, Canada similar

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has
been driven in either miles, used in the United States,
or kilometers, used in Canada.
Trip Odometer
The trip odometer can record the number of miles, used
in the United States, or kilometers, used in Canada,
traveled for up to two trips.
You can cycle between the odometer and trip
odometers A and B by pressing the reset button located
in the lower right area of the speedometer. By pressing
the reset button, you can tell how many miles or
kilometers have been recorded on either Trip A or Trip B
since you last set the trip odometer back to zero.
To reset each trip odometer to zero, press and hold the
reset button. The reset button resets only the trip
odometer that is being displayed. Each trip odometer
must be reset individually.
Tachometer
The tachometer
displays your engine
speed in revolutions
per minute (rpm).
Safety Belt Reminder Tone
If your vehicle has this feature, a tone will sound for
several seconds when the ignition is turned to ON
to remind people to fasten their safety belts. The tone
will not sound if the driver’s safety belt is already
buckled.

Passenger Airbag Status Indicator
Your vehicle has a passenger airbag status indicator in
the clock, located in the center of the instrument panel.
When the ignition key is turned to ON or START, the
passenger airbag status indicator will light for several
seconds as a system check. Then, after several
more seconds, if the off symbol is lit on the passenger
airbag status indicator, it means that the passenger
sensing system has turned off the right front passenger’s
frontal airbag and side airbag (if equipped). See
Passenger Sensing System on page 1-65for more on
this, including important safety information.
If the off symbol is not lit on the passenger airbag status
indicator, it means that the right front passenger’s
frontal airbag and side airbag (if equipped) are enabled
(may inflate).{CAUTION:
If the off symbol in the passenger airbag
status indicator does not come on when you
have a rear-facing child restraint installed in
the right front passenger’s seat, it means that
the passenger sensing system has not turned
off the passenger’s frontal airbag and side
airbag (if equipped). A child in a rear-facing
child restraint can be seriously injured or killed
if the right front passenger’s airbag or airbags
inate. This is because the back of the
rear-facing child restraint would be very close
to the inating airbag or airbags. Do not use a
rear-facing child restraint in the right front
passenger’s seat unless the airbag or airbags
have been turned off. United States

{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on, it
means that something may be wrong with the
airbag system. If this ever happens, have the
vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger’s seat may not have the protection
of the frontal airbag and side airbag (if
equipped). SeeAirbag Readiness Light on
page 3-32for more on this, including important
safety information.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light
comes on, there is a
brake problem. Have your
brake system inspected
right away.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake does not fully
release. If it stays on after your parking brake is fully
released, it means you have a brake problem.
3-27

If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push or the pedal may go closer to the
floor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeTowing
Your Vehicle on page 4-34.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you have pulled off the road and
stopped carefully, have the vehicle towed for
service.
Engine Coolant Temperature Gage
Your vehicle has an engine coolant temperature gage.
With the ignition to ON, this gage shows the engine
coolant temperature.
If the gage pointer moves into the red area, your engine
is too hot. It means that your engine coolant has
overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
SeeEngine Overheating on page 5-24. United States

Cruise Control Light
If equipped, this light
comes on whenever you
set your cruise control.
The light will go out when the cruise control is turned
off. SeeCruise Control on page 3-10for more
information.
Highbeam On Light
This light comes on
whenever the high-beam
headlamps are on.
SeeHeadlamp High/Low-Beam Changer on page 3-8
for additional information.
Daytime Running Lamps (DRL)
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 your GM dealer.
SeeDaytime Running Lamps (DRL) on page 3-14for
more information.
