CHEVROLET AVEO 2002 Service Repair Manual

For some children who have outgrown child restraints
and for very small adults, the passenger sensing system
may or may not turn off the right front passenger’s
frontal airbag and side airbag (if equipped), depending
upon the person’s seating posture and body build.
Everyone in your vehicle who has outgrown child
restraints should wear a safety belt properly — whether
or not there is an airbag for that person.
If a person of adult-size is sitting in the right front
passenger’s seat, but the off symbol is lit, it could be
because that person is not sitting properly in the seat.
If this happens do the following:
Turn the vehicle off and ask the person to place the
seatback in the fully upright position, then sit upright in
the seat, centered on the seat cushion, with the
person’s legs comfortably extended. Restart the vehicle
and have the person remain in this position for about
two minutes. This will allow the system to detect
that person and then enable the passenger’s airbag or
airbags.
1-68

{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.
A thick layer of additional material such as a blanket,
or aftermarket equipment such as seat covers, seat
heaters and seat massagers can affect how well
the passenger sensing system operates. Remove any
additional material from the seat cushion before
reinstalling or securing the child restraint or small
occupant. You may want to consider not using seat
covers or other aftermarket equipment if your vehicle
has the passenger sensing system. SeeAdding
Equipment to Your Airbag-Equipped Vehicle on
page 1-70for more information about modifications
that can affect how the system operates.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. You do not want the system to
inflate while someone is working on your vehicle.
Your dealer and the service manual have information
about servicing your vehicle and the airbag system.
To purchase a service manual, seeService Publications
Ordering Information on page 7-15.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
airbag can still inate during improper service.
You can be injured if you are close to an
airbag when it inates. Avoid yellow
connectors. They are probably part of the
airbag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualied to do so.
The airbag system does not need regular maintenance.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front or
sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Also, the airbag system may
not work properly if you relocate any of the airbag
sensors. If you have any questions about this,
you should contact Customer Assistance before you
modify your vehicle. The phone numbers and
addresses for Customer Assistance are in Step Two
of the Customer Satisfaction Procedure in this
manual. SeeCustomer Satisfaction Procedure on
page 7-2.
Q:Because I have a disability, I have to get my
vehicle modied. How can I nd out whether
this will affect my airbag system?
A:Changing or moving any parts of the front seats,
safety belts, the airbag sensing and diagnostic
module, steering wheel, the instrument panel, or
airbag wiring can affect the operation of the airbag
system. If you have questions, call Customer
Assistance. The phone numbers and addresses for
Customer Assistance are in Step Two of the
Customer Satisfaction Procedure in this manual.
SeeCustomer Satisfaction Procedure on page 7-2.

Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.Also look for any opened or broken airbag covers, and
have them repaired or replaced. (The airbag system
does not need regular maintenance.)
Notice:If you damage the covering for the driver’s
or the right front passenger’s frontal airbag, or an
airbag covering (if equipped) on a seatback, the
airbag may not work properly. You may have to
replace the airbag module in the steering wheel, both
the airbag module and the instrument panel for the
right front passenger’s frontal airbag, or both the
airbag module and the seatback for seating positions
with a side impact airbag (if equipped.) Do not open
or break the airbag coverings.
1-71

Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems in
your vehicle. A damaged restraint system may
not properly protect the person using it,
resulting in serious injury or even death in a
crash. To help make sure your restraint
systems are working properly after a crash,
have them inspected and any necessary
replacements made as soon as possible.
If you have had a crash, do you need new or LATCH
system parts?
After a very minor collision, nothing may be necessary.
But if the belts were stretched, as they would be if
worn during a more severe crash, then you need
new parts.
If the LATCH system was being used during a more
severe crash, you may need new LATCH system parts.If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have LATCH
system, safety belt or seat parts repaired or replaced.
New parts and repairs may be necessary even if the belt
or LATCH system was not being used at the time of
the collision.
If the frontal airbags inflate, you will also need to
replace the driver’s and right front passenger’s safety
belt pretensioners and safety belt. Be sure to do
so. Then the new pretensioner and safety belt will be
there to help protect you in a collision.
After a crash you may need to replace the driver and
right front passenger’s safety belt retractor assemblies,
even if the frontal airbags have not deployed. The
driver and right front passenger’s safety belt retractor
assemblies contain the safety belt pretensioners.
Have your safety belt pretensioners checked if your
vehicle has been in a collision, or if your airbag
readiness light stays on after you start your vehicle or
while you are driving. SeeAirbag Readiness Light
on page 3-32.
If an airbag inflates, you will need to replace airbag
system parts. See the part about the airbag system
earlier in this section.

Section 2 Features and Controls
2-1

Keys
{CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons. They
could operate the power windows or other
controls or even make the vehicle move. The
children or others could be badly injured or
even killed. Do not leave the keys in a vehicle
with children.
2-2

One key is used for the
ignition, the doors and all
other locks.
When a new vehicle is delivered, the dealer removes the
key tag and gives it to the first owner. The tag has a code
on it that tells your dealer how to make extra keys. For
vehicle security, keep the key tag in a safe place and also
record the key number somewhere other than inside of
the vehicle. If you lose your key, you will be able to have
a new one made easily using the tag.Your vehicle may have an electronic immobilizer
designed to protect your car against theft. If so, only
keys with the correct electronic code can be used
to start the vehicle. SeeImmobilizer Operation on
page 2-16for additional information. Even if a key has
the same profile, it will not start the engine if the
electronic code is incorrect. If you need a new key,
contact your dealer who can obtain the correct key code.
Also seeRoadside Assistance Program on page 7-6.
Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.
2-3

Remote Keyless Entry System
If the vehicle has the keyless entry system, it operates
on a radio frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired

2-4

Remote Keyless Entry System
Operation
You can lock and unlock your vehicle’s doors from
about 20 ft (6 m) away using the remote keyless entry
transmitter.
The following functions are
available if your vehicle
has the remote keyless
entry system:
Q(Lock):Press this button to lock all of the doors.
If all of the doors and the trunk or liftgate are closed, the
hazard lamps will flash once and the horn will chirp to
indicate that locking has occurred and that the
theft-deterrent system is active.
K(Unlock):Press this button to unlock all of the
doors. The hazard lamps will flash twice to indicate that
unlocking has occurred and that the theft-deterrent
system is deactivated.
The LED light, on the transmitter, will flash when the
buttons on the transmitter are pressed.
The lock and unlock buttons will not operate and the
theft-deterrent system will not activate while the key
is in the ignition.
Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your dealer. Remember to bring
any remaining transmitters with you when you go to
your dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of
five transmitters matched to it.
