2004 CHEVROLET EPICA 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. Don’t let seat covers block the
ination path of a side impact air bag.
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.
1-51

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
frontal and side impact air bags, the sensing system
triggers a release of gas from the inflator, which inflates
the air bag. The inflator, the 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 side impact air bags,
the air bag modules are located in the seatback closest to
the driver’s and/or right front passenger’s door.
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. Side impact air bags 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 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 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 and right front passenger’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 – the
steering wheel hub for the driver’s air bag, the instrument
panel for the right front passenger’s bag, the side of the
seatback closest to the door for the driver’s side impact
air 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
does not 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
CAUTION: (Continued)
CAUTION: (Continued)
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 will need some new parts for
your air bag system. If you do not get them, the air
bag system will not 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.
1-53

•Your vehicle is equipped with a crash sensing
and diagnostic module, which records information
about the frontal 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 will not 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 an air
bag covering on a 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 a 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 7-12.
{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.
1-54

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 have 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 severe crash, then you need new parts.
If the LATCH system was being used during a more
severe crash, you may need new LATCH system parts.
1-55

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 the frontal air bags inflate, you will also need to
replace the driver’s and right front passenger’s safety
belt pretentioners and safety belt. Be sure to do
so. Then the new pretensioner and safety belt will be
there to help protect you in a collision.
After a crash you may need to replace the driver and
right front passenger’s safety belt retractor assemblies,
even if the frontal air bags have not deployed. The
driver and right front passenger’s safety belt retractor
assemblies contain the safety belt pretensioners.Have your safety belt pretensioners checked if your
vehicle has been in a collision, or if your air bag
readiness light stays on after you start your vehicle or
while you are driving. SeeAir Bag Readiness Light
on page 3-33.
If your vehicle is equipped with side air bags, the front
seat assembly must be replaced after the side air
bag has been deployed.
If an air bag inflates, you will need to replace air bag
system parts. See the part on the air bag system earlier
in this section.
