2004 CHEVROLET CORVETTE Owners Manual

{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.
When Should an Air Bag Inate?
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
“threshold level.” If your vehicle goes straight into a
wall that does not 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, rear impacts, or in many side 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.
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. 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.
1-43

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 many
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
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 – the
steering wheel hub for the driver’s air bag, 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 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.
{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.
CAUTION: (Continued)
1-44

CAUTION: (Continued)
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 not 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 the 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 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 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. The module also records
speed, engine rpm, brake and throttle data.
•Let only qualified technicians work on your air bag
systems. Improper service can mean that an 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.
1-45

Air Bag Off Switch
Your vehicle has a switch in the glove box that you can
use to turn off the passenger’s air bag.This switch should only be turned to AIR BAG OFF if
the person in the passenger’s position is a member of a
passenger risk group identified by the national
government as follows:
Infant.An infant (less than 1 year old) must
ride in the front seat because:
•
my vehicle has no rear seat;
•my vehicle has a rear seat too small to
accommodate a rear-facing infant seat; or
•the infant has a medical condition which, according
to the infant’s physician, makes it necessary for the
infant to ride in the front seat so that the driver
can constantly monitor the child’s condition.
Child age 1 to 12.A child age 1 to 12 must
ride in the front seat because:
•
my vehicle has no rear seat;
•although children ages 1 to 12 ride in the rear
seat(s) whenever possible, children ages 1 to 12
sometimes must ride in the front because no space
is available in the rear seat(s) of my vehicle; or
•the child has a medical condition which, according
to the child’s physician, makes it necessary for the
child to ride in the front seat so that the driver
can constantly monitor the child’s condition.
1-46

Medical Condition.A passenger has a
medical condition which, according to his or
her physician:
•
causes the passenger air bag to pose a special risk
for the passenger; and
•makes the potential harm from the passenger air
bag in a crash greater than the potential harm
from turning off the air bag and allowing the
passenger, even if belted, to hit the dashboard or
windshield in a crash.
{CAUTION:
If the passenger’s air bag is turned off for a
person who isn’t in a risk group identied by
the national government, that person won’t
have the extra protection of an air bag. In a
crash, the air bag wouldn’t be able to inate
and help protect the person sitting there. Don’t
turn off the passenger’s air bag unless the
person sitting there is in a risk group.To turn off the passenger’s air bag, insert your ignition
key into the switch, push in, and move the switch to
the off position.
1-47

The air bag off light on the center console switch panel
will come on to let you know that the passenger’s air
bag is off. The passenger’s air bag will remain off until
you turn it back on again, and the air bag off light
will stay on to remind you that the air bag is off.
To turn the passenger’s air bag on again, insert your
ignition key into the switch, push in, and move the switch
to the on position.

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, 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 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 qualied to do so.
The air bag system does 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.)

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’ve had a crash, do you need new belts?
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 you ever see a label on the driver’s safety belt that
says to replace the belt, be sure to do so. Then the new
belt will be there to help protect you in a collision.
You would see this label on the belt near the latch plate.
If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have safety belt
or seat parts repaired or replaced. New parts and
repairs may be necessary even it the belt wasn’t being
used at the time of the collision.
If an air bag inflates, you’ll need to replace air bag
system parts. See the part on the air bag system earlier
in this section.
