CHEVROLET ASTRO CARGO VAN 2004 2.G Manual PDF

{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 inate in a moderate to severe
frontal, or near-frontal crash. The air bag will inate
only if the impact speed is above the system’s designed
“threshold level”. If your vehicle goes straight into a
wall that doesn’t move or deform, the threshold level is
about 9 to 16 mph (14 to 26 mph/h). The threshold
level can vary, however, with specic 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 inate in
rollovers, rear impacts, or in many side impacts because
ination would not help the occupant.
In any particular crash, no one can say whether an air
bag should have inated simply because of the damage
to a vehicle or because of what the repair costs were.
Ination 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
inator, which inates the air bag. The inator, 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 right front passenger.
1-65

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 an air bag inates, it quickly deates, so quickly that
some people may not even realize the air bag inated.
Some components of the air bag module — the steering
wheel hub for the driver’s air bag, or the instrument
panel for the right front 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 deated air bags. Air bag ination 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. 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.
1-66

Air bags are designed to inate only once. After they
inate, 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 ination and driver’s safety belt
usage at deployment. The module also records
speed, engine rpm, brake and throttle data.
Let only qualied 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, 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 right front passenger’s 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 system in several places
around your vehicle. You don’t want the system to
inate 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 7-12.
{CAUTION:
For up to 10 minutes 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 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.

Adding Equipment to Your
Air Bag-Equipped Vehicle
Q:Is there anything I might add to the front of
the vehicle that could keep the air bags from
working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, front end sheet metal or
height, they may keep the air bag system from
working properly. Also, the air bag system may
not work properly if you relocate any of the air bag
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 theCustomer Satisfaction Procedure
on page 7-2.
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 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 sever crash, the you need new 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 wasn’t being used at the time of
the collision.
If your seat adjuster won’t work after a crash, the
special part of the safety belt that goes through the
seat to the adjuster may need to be replaced.
If an air bag inates, you’ll need to replace air bag
system parts. See the part on the air bag system
earlier in this section.
