CHEVROLET AVEO 2008 1.G Repair Manual

{CAUTION:
Frontal airbags are designed to deploy in
moderate to severe frontal and near frontal
crashes. They are not designed to inate
in rollover, rear crashes, or in many side
crashes.
Seat-mounted side impact airbags are
designed to inate in moderate to severe
crashes where something hits the side of
your vehicle. They are not 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 is an
airbag for that person.
{CAUTION:
Airbags inate with great force, faster than
the blink of an eye. Anyone who is up against,
or very close to, any airbag when it inates
can be seriously injured or killed. Do not sit
unnecessarily close to the airbag, as you
would be if you were sitting on the edge of
your seat or leaning forward. Safety belts
help keep you in position before and during a
crash. Always wear your safety belt, even with
airbags. The driver should sit as far back as
possible while still maintaining control of
the vehicle.
Occupants should not lean on or sleep against
the door or side windows in seating positions
with seat-mounted airbags.

{CAUTION:
Airbags 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 airbag 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
Older Children on page 1-32orInfants and
Young Children on page 1-34.There is an airbag
readiness light on the
instrument panel, which
shows the airbag symbol.
The system checks the airbag electrical system for
malfunctions. The light tells you if there is an electrical
problem. SeeAirbag Readiness Light on page 3-30
for more information.
1-58

Where Are the Airbags?
The driver’s frontal airbag is in the middle of the
steering wheel.The right front passenger’s frontal airbag is in the
instrument panel on the passenger’s side.
1-59

If your vehicle has seat-mounted side impact airbags
for the driver and right front passenger, they are in
the side of the seatbacks closest to the door.
{CAUTION:
If something is between an occupant and an
airbag, the airbag might not inate properly
or it might force the object into that person
causing severe injury or even death. The path
of an inating airbag must be kept clear.
Do not put anything between an occupant and
an airbag, and do not attach or put anything
on the steering wheel hub or on or near any
other airbag covering.
Do not use seat accessories that block the
ination path of a seat-mounted side impact
airbag.

When Should an Airbag Inate?
Frontal airbags are designed to inflate in moderate to
severe frontal or near-frontal crashes to help reduce
the potential for severe injuries mainly to the driver’s
or right front passenger’s head and chest. However,
they are only designed to inflate if the impact exceeds
a predetermined deployment threshold. Deployment
thresholds are used to predict how severe a crash
is likely to be in time for the airbags to inflate and help
restrain the occupants.
Whether your frontal airbags will or should deploy is not
based on how fast your vehicle is traveling. It depends
largely on what you hit, the direction of the impact,
and how quickly your vehicle slows down.Frontal airbags may inflate at different crash speeds.
For example:•If the vehicle hits a stationary object, the airbags
could inflate at a different crash speed than if the
vehicle hits a moving object.
•If the vehicle hits an object that deforms, the
airbags could inflate at a different crash speed than
if the vehicle hits an object that does not deform.
•If the vehicle hits a narrow object (like a pole), the
airbags could inflate at a different crash speed
than if the vehicle hits a wide object (like a wall).
•If the vehicle goes into an object at an angle, the
airbags could inflate at a different crash speed
than if the vehicle goes straight into the object.
Thresholds can also vary with specific vehicle design.
1-61

In addition, your vehicle has dual-stage frontal airbags.
Dual-stage airbags adjust the restraint according to
crash severity. Your vehicle has electronic frontal
sensors, which help the sensing system distinguish
between a moderate frontal impact and a more severe
frontal impact. For moderate frontal impacts, dual-stage
airbags inflate at a level less than full deployment.
For more severe frontal impacts, full deployment occurs.
Frontal airbags are not intended to inflate during
vehicle rollovers, rear impacts, or in many side impacts.
Your vehicle may or may not have seat-mounted
side impact airbags. SeeAirbag System on page 1-56.
Seat-mounted side impact airbags are intended
to inflate in moderate to severe side crashes.
Seat-mounted side impact airbags will inflate if the
crash severity is above the system’s designed
threshold level. The threshold level can vary with
specific vehicle design.Seat-mounted side impact airbags are not intended to
inflate in frontal impacts, near-frontal impacts, rollovers,
or rear impacts. A seat-mounted side impact airbag
is intended to deploy on the side of the vehicle that
is struck.
In any particular crash, no one can say whether an
airbag should have inflated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, inflation is determined by
what the vehicle hits, the angle of the impact, and how
quickly the vehicle slows down. For seat-mounted
side impact airbags, deployment is determined by the
location and severity of the side impact.
1-62

What Makes an Airbag Inate?
In a deployment event, the sensing system sends
an electrical signal triggering a release of gas from
the inflator. Gas from the inflator fills the airbag
causing the bag to break out of the cover and deploy.
The inflator, the airbag, and related hardware are
all part of the airbag module.
Frontal airbag modules are located inside the
steering wheel and instrument panel. For vehicles
with seat-mounted side impact airbags, there are
airbag modules in the side of the front seatbacks
closest to the door.
How Does an Airbag 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.
Airbags supplement the protection provided by safety
belts. Frontal airbags distribute the force of the
impact more evenly over the occupant’s upper body,
stopping the occupant more gradually. Seat-mounted
side impact airbags distribute the force of the impact
more evenly over the occupant’s upper body.
But airbags would not help in many types of collisions,
primarily because the occupant’s motion is not
toward those airbags. SeeWhen Should an Airbag
Inflate? on page 1-61for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.
1-63

What Will You See After an
Airbag Inates?
After the frontal and seat-mounted side impact airbags
inflate, they quickly deflate, so quickly that some
people may not even realize the airbags inflated.
Some components of the airbag module may be hot
for several minutes. For location of the airbag modules,
seeWhat Makes an Airbag Inflate? on page 1-63.
The parts of the airbag that come into contact with you
may be warm, but not too hot to touch. There may
be some smoke and dust coming from the vents in the
deflated airbags. Airbag inflation does not prevent
the driver from seeing out of the windshield or being
able to steer the vehicle, nor does it prevent people
from leaving the vehicle.
{CAUTION:
When an airbag inates, there may be 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 cannot get out of the vehicle after an airbag
inates, then get fresh air by opening a window
or a door. If you experience breathing problems
following an airbag deployment, you should
seek medical attention.
Your vehicle has a feature that may automatically
unlock the doors, turn the interior lamps on, and turn on
the hazard warning flashers when the airbags inflate.
You can lock the doors, turn the interior lamps off,
and turn the hazard warning flashers off by using the
controls for those features.

In many crashes severe enough to inflate the airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from
the right front passenger airbag.
•Airbags are designed to inflate only once. After an
airbag inflates, you will need some new parts for
the airbag system. If you do not get them, the airbag
system will not be there to help protect you in
another crash. A new system will include airbag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
•Your vehicle has a crash sensing and diagnostic
module which records information after a crash.
SeeVehicle Data Recording and Privacy on
page 7-18andEvent Data Recorders on page 7-19.
•Let only qualified technicians work on the airbag
system. Improper service can mean that the
airbag system will not work properly. See your
dealer/retailer for service.
Passenger Sensing System
Your vehicle has a passenger sensing system for the
right front passenger’s position. The passenger airbag
status indicator will be visible when you start your vehicle.
If you have a sedan, the airbag off symbol will be visible
near the clock, located in the center of the instrument
panel, during the system check. SeePassenger
Airbag Status Indicator (Sedan) on page 3-31. United States – Sedan
Canada – Sedan
1-65

If you have a hatchback, the airbag off symbol will be
visible in the Secondary Information Center (SIC) during
the system check. SeeSecondary Information Center
(SIC) (Hatchback Only) on page 3-43. When the system
check is complete, the airbag off symbol will be visible
under certain conditions.
The passenger sensing system will turn off the right
front passenger’s frontal airbag and seat-mounted side
impact airbag (if equipped) under certain conditions.
The driver’s airbags are not part of the passenger
sensing system.The passenger sensing system works with a sensor that
is part of the right front passenger’s seat. The sensor
is designed to detect the presence of a properly-seated
occupant and determine if the right front passenger’s
frontal airbag and seat-mounted side impact airbag
(if equipped) should be enabled (may inflate) or not.
Accident statistics show that children are safer if
they are restrained in the rear rather than the front seat.
We recommend that children be secured in a rear
seat, including: an infant or a child riding in a rear-facing
child restraint; a child riding in a forward-facing child
seat; an older child riding in a booster seat; and children,
who are large enough, using safety belts.
A label on your sun visor says, “Never put a rear-facing
child seat in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys. United States –
