CHEVROLET CORVETTE 2000 5.G Service Manual

1-23
CAUTION:
If something is between an occupant and an
air bag, the bag might not inflate properly or it
might force the object into that person. The path
of an inflating 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.
When should an air bag inflate?
An air bag is designed to inflate in a moderate to severe
frontal or near
-frontal crash. The air bag will inflate
only if the impact speed is above the system's designed
ªthreshold level.º If your vehicle goes straight into a
wall that doesn't move or deform, the threshold level is
about 9 to 15 mph (14 to 24 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 air bag is not designed to inflate in rollovers, side
impacts 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.
Inflation is determined by the angle of the impact and
how quickly the vehicle slows down in frontal or
near
-frontal impacts.

1-24
What makes an air bag inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. 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 inside the
steering wheel and in the instrument panel in front of
the passenger.
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. Air bags supplement 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 air bags
would not help you in many types of collisions,
including rollovers, rear impacts and side impacts,
primarily because an occupant's motion is not toward
those air bags. 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.What will you see after an air bag inflates?
After an 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
-- the
steering wheel hub for the driver's air bag, or the
instrument panel for the passenger's bag
-- will be hot
for a short time. 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 vents
in the deflated air bags. Air bag inflation doesn't prevent
the driver from seeing or from being able to steer the
vehicle, nor does it stop people from leaving the vehicle.
CAUTION:
When an air bag inflates, 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 inflates, then get
fresh air by opening a window or door.

1-25
In many crashes severe enough to inflate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
passenger air bag.

Air bags are designed to inflate only once. After they
inflate, 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 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. Some modules also record speed,
engine rpm, brake and throttle data.

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 passenger's air bag, the bag may not work
properly. You may have to replace the air bag
module in the steering wheel or both the air
bag module and the instrument panel for the
passenger's air bag. Do not open or break the
air bag coverings.

1-26 Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag system in several places
around your vehicle. You don't 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 air bag system.
To purchase a service manual, see ªService and Owner
Publicationsº in the Index.
CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service. You
can be injured if you are close to an air bag when
it inflates. Avoid yellow wires, wires wrapped
with yellow tape or 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 qualified
to do so.
The air bag system does not need regular maintenance.
Children
Everyone in a vehicle needs protection! That includes
infants and all children smaller than adult size. Neither
the distance to be traveled nor the age and size of the
traveler changes the need, for everyone, to use safety
restraints. In fact, the law in every state in the United
States and in every Canadian province says children up
to some age must be restrained while in a vehicle.
Smaller Children and Babies
CAUTION:
Children who are up against, or very close to, any
air bag when it inflates 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.

1-27
CAUTION:
A very young child's hip bones are so small that a
regular belt might not stay low on the hips, as it
should. Instead, the belt will likely be over the
child's abdomen. In a crash, the belt would apply
force right on the child's abdomen, which could
cause serious or fatal injuries. Smaller children
and babies should always be restrained in a
child restraint. However, infants, who should be
restrained in a rear
-facing child restraint, cannot
ride safely in this vehicle. The instructions for
the restraint will say whether it is the right type
and size for your child. If a forward
-facing child
restraint is suitable for your child, be sure the
child is always properly restrained while riding
in this vehicle.
Infants need complete support, including support for
the head and neck. This is necessary because an infant's
neck is weak and its head weighs so much compared
with the rest of its body. In a frontal crash, an infant in a
rear
-facing restraint settles into the restraint, so the crash
forces can be distributed across the strongest part of the
infant's body, the back and shoulders. A baby should
be secured in an appropriate infant restraint, but you
shouldn't secure that type of restraint in this vehicle
because of the air bag risk.

1-28
CAUTION:
Never hold a baby in your arms while riding in
a vehicle. A baby doesn't weigh much
-- until a
crash. During a crash a baby will become so
heavy you can't hold it. For example, in a crash
at only 25 mph (40 km/h), a 12
-lb. (5.5 kg) baby
will suddenly become a 240
-lb. (110 kg) force on
your arms. The baby would be almost impossible
to hold.

1-29
Child Restraints
Every time infants and young children ride in
vehicles, they should have protection provided by
appropriate restraints.
Q:What are the different types of add-on
child restraints?
A:Add-on child restraints are available in four basic
types. When selecting a child restraint, take into
consideration not only the child's weight and size,
but also whether or not the restraint will be
compatible with the motor vehicle in which it
will be used.
An infant car bed (A) is a special bed made for use
in a motor vehicle. It's an infant restraint system
designed to restrain or position a child on a
continuous flat surface. With an infant car bed,
make sure that the infant's head rests toward the
center of the vehicle.

1-30
A rear-facing infant restraint (B) positions an infant
to face the rear of the vehicle. Rear
-facing infant
restraints are designed for infants of up to about
20 lbs. (9 kg) and about one year of age. This type
of restraint faces the rear so that the infant's head,
neck and body can have the support they need in
a frontal crash. Some infant seats come in two
parts
-- the base stays secured in the vehicle and
the seat part is removable.

1-31
A forward-facing child restraint (C-E) positions
a child upright to face forward in the vehicle. These
forward
-facing restraints are designed to help
protect children who are from 20 to 40 lbs. (9 to
18 kg) and about 26 to 40 inches (66 to 102 cm) in
height, or up to around four years of age. One type,
a convertible restraint, is designed to be used either
as a rear
-facing infant seat or a forward-facing
child seat.

1-32
A booster seat (F) is designed for children who
are about 40 to 60 lbs., or even up to 80 lbs.
(18 to 27 kg, or even up to 36 kg), and about four
to eight years of age. A booster seat is designed to
improve the fit of the vehicle's safety belt system.
Booster seats with shields use lap
-only belts;
however, booster seats without shields use
lap
-shoulder belts. Booster seats can also help a
child to see out the window.When choosing a child restraint, be sure the child
restraint is designed to be used in a vehicle. If it is,
it will have a label saying that it meets federal motor
vehicle safety standards.
Then follow the instructions for the restraint. You may
find these instructions on the restraint itself or in a
booklet, or both. These restraints use the belt system in
your vehicle, but the child also has to be secured within
the restraint to help reduce the chance of personal injury.
The instructions that come with the child restraint will
show you how to do that. Both the owner's manual and
the child restraint instructions are important, so if either
one of these is not available, obtain a replacement copy
from the manufacturer.
The child restraint must be secured properly in the
passenger seat.
Keep in mind that an unsecured child restraint can move
around in a collision or sudden stop and injure people
in the vehicle. Be sure to properly secure any child
restraint in your vehicle
-- even when no child is in it.
