2004 CHEVROLET AVEO Owners Manual

CAUTION: (Continued)
And, for some unrestrained occupants, frontal
air bags may provide less protection in frontal
crashes than more forceful air bags have
provided in the past.
The side impact air bag for the driver is
designed to inate only in moderate to severe
crashes where something hits the driver’s side
of your vehicle. It isn’t designed to inate in
frontal, in rollover or in rear crashes.
Everyone in your vehicle should wear a safety
belt properly, whether or not there’s an air bag
for that person.
{CAUTION:
Both frontal and side impact air bags inate
with great force, faster than the blink of an
eye. If you’re too close to an inating air bag,
as you would be if you were leaning forward,
it could seriously injure you. Safety belts help
keep you in position for air bag ination before
and during a crash. Always wear your safety
belt, even with frontal air bags. The driver
should sit as far back as possible while still
maintaining control of the vehicle, and should
not lean on the door.
1-51

{CAUTION:
Anyone who is up against, or very close to,
any air bag when it inates can be seriously
injured or killed. Air bags plus lap-shoulder
belts offer the best protection for adults, but
not for young children and infants. Neither the
vehicle’s safety belt system nor its air bag
system is designed for them. Young children
and infants need the protection that a child
restraint system can provide. Always secure
children properly in your vehicle. To read how,
see the part of this manual called “Older
Children” or “Infants and Young Children.”There is an air bag
readiness light on the
secondary information
center, which shows the
air bag symbol.
The system checks the air bag electrical system for
malfunctions. The light tells you if there is an electrical
problem. SeeAir Bag Readiness Light on page 3-26
for more information.

Where Are the Air Bags?
The driver’s air bag is in the middle of the steering wheel.The right front passenger’s air bag is in the instrument
panel on the passenger’s side.
1-53

If your vehicle has one, the driver’s side impact air bag
is in the side of the driver’s seatback closest to the door.
{CAUTION:
If something is between an occupant and an
air bag, the bag might not inate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inating air bag must be kept clear. Don’t put
anything between an occupant and an air bag,
and don’t attach or put anything on the
steering wheel hub or on or near any other
air bag covering. Don’t let seat covers block
the ination path of a side impact air bag.
1-54

When Should an Air Bag Inate?
The driver’s and right front passenger’s frontal air bags
are designed to inflate in moderate to severe frontal
or near-frontal crashes. But they are designed to inflate
only if the impact speed is above the system’s
designed “threshold level.”
If the front of your vehicle goes straight into a wall that
doesn’t move or deform, the threshold level is about
9 to 14 mph (14.5 to 23 km/h). The threshold level can
vary, however, with specific vehicle design, so that
it can be somewhat above or below this range.
If your vehicle strikes something that will move or
deform, such as a parked car, the threshold level will be
higher. The driver’s and right front passenger’s frontal
air bags are not designed to inflate in rollovers, rear
impacts, or in many side impacts because inflation
would not help the occupant.
Your vehicle may or may not have a side impact air
bag. See “Air Bag Systems” in the Index. A driver’s side
impact air bag is designed to inflate in moderate to
severe side crashes involving the driver’s door. A side
impact air bag will inflate if the crash severity is above
the system’s designed “threshold level.” The threshold
level can vary with specific vehicle design. A driver’s
side impact air bag is not designed to inflate in frontal or
near-frontal impacts, rollovers or rear impacts, because
inflation would not help the occupant.In any particular crash, no one can say whether an air
bag should have inflated simply because of the damage
to a vehicle or because of what the repair costs were.
For frontal air bags, inflation is determined by the angle
of the impact and how quickly the vehicle slows down
in frontal and near-frontal impacts. For side impact
air bags, inflation is determined by the location
and severity of the impact.
What Makes an Air Bag Inate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. For both
the frontal and side impact air bags, the sensing system
triggers a release of gas from the inflator, which
inflates the air bag. The inflator, air bag and related
hardware are all part of the air bag modules. Frontal air
bag modules are located inside the steering wheel
and instrument panel. For vehicles with a driver’s side
impact air bag, the air bag modules are located in
the seatback closest to the driver’s door.
1-55

How Does an Air Bag Restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel
or the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle. The air bag supplements the protection
provided by safety belts. Air bags distribute the force
of the impact more evenly over the occupant’s upper
body, stopping the occupant more gradually. But the
frontal air bags would not help you in many types
of collisions, including rollovers, rear impacts, and many
side impacts, primarily because an occupant’s motion
is not toward the air bag. A side impact air bag
would not help you in many types of collisions, including
frontal or near frontal collisions, rollovers, and rear
impacts, primarily because an occupant’s motion is not
toward that air bag. Air bags should never be regarded
as anything more than a supplement to safety belts,
and then only in moderate to severe frontal or
near-frontal collisions for the driver’s and right front
passenger’s frontal air bags, and only in moderate to
severe side collisions for vehicles with a driver’s
side impact air bag.
What Will You See After an
Air Bag Inates?
After the air bag inflates, it quickly deflates, so quickly
that some people may not even realize the air bag
inflated. Some components of the air bag module will be
hot for a short time. These components include the
steering wheel hub for the driver’s frontal air bag and the
instrument panel for the right front passenger’s frontal
air bag. For vehicles with a side impact air bag, the side
of the seatback closest to the driver’s door will be
hot. The parts of the bag that come into contact with
you may be warm, but not too hot to touch. There will be
some smoke and dust coming from the vents in the
deflated air bags. Air bag inflation doesn’t prevent the
driver from seeing or being able to steer the vehicle,
nor does it stop people from leaving the vehicle.
1-56

{CAUTION:
When an air bag inates, there is dust in the
air. This dust could cause breathing problems
for people with a history of asthma or other
breathing trouble. To avoid this, everyone in
the vehicle should get out as soon as it is safe
to do so. If you have breathing problems but
can’t get out of the vehicle after an air bag
inates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an air bag deployment,
you should seek medical attention.
In many crashes severe enough to inflate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from
the right front passenger air bag.
•Air bags are designed to inflate only once. After an
air bag inflates, you’ll need some new parts for your
air bag system. If you don’t get them, the air bag
system won’t be there to help protect you in another
crash. A new system will include air bag modules
and possibly other parts. The service manual for your
vehicle covers the need to replace other parts.
•Your vehicle is equipped with a crash sensing and
diagnostic module, which records information about
the air bag system. The module records information
about the readiness of the system,
when the system commands air bag inflation and
driver’s safety belt usage at deployment.
•Let only qualified technicians work on your air bag
system. Improper service can mean that your air bag
system won’t work properly. See your dealer for
service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s air bag, or the air bag
covering on the driver’s seatback, the bag may not
work properly. You may have to replace the air bag
module in the steering wheel, both the air bag
module and the instrument panel for the right front
passenger’s air bag, or the air bag module and
seatback for the driver’s side impact air bag.
Do not open or break the air bag coverings.

Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the air
bag systems. To purchase a service manual, seeService
Publications Ordering Information on page 7-11.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected,
an air bag can still inate during improper
service. You can be injured if you are close
to an air bag when it inates. Avoid yellow
connectors. They are probably part of the air
bag system. Be sure to follow proper service
procedures, and make sure the person
performing work for you is qualied to do so.
The air bag systems do not need regular maintenance.
Restraint System Check
Checking Your 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 air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)
