CHEVROLET MALIBU 2004 5.G Repair Manual

The right front passenger’s air bag is in the instrument
panel on the passenger’s side.If your vehicle has a side impact air bag for the driver
and the person seated directly behind the driver, it
is located in the ceiling above the side windows.
1-55

If your vehicle has a side impact air bag for the right
front passenger and the person directly behind that
passenger, it is located in the ceiling above the
side windows.
{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. And, because your vehicle has
side impact air bags, never secure anything to
the roof of your vehicle by routing the rope or
tiedown through any door or window opening.
If you do, the path of an inating side impact
air bag will be blocked. The path of an inating
air bag must be kept clear.

When Should an Air Bag Inate?
The driver’s and right front passengers frontal air bags
are designed to deploy only in moderate to severe
frontal, or near-frontal crashes. But they are designed to
inate only if the impact speed is above the system’s
designed “threshold level.”
In addition, your vehicle has “dual stage” frontal air
bags, which adjust the amount of restraint according to
crash severity. For moderate frontal impacts, these
air bags inate at a level less than full deployment. For
more severe frontal impacts, full deployment occurs.
If the front of your vehicle goes straight into a wall that
doesn’t move or deform, the threshold level for the
reduced deployment is about 12 to 16 mph
(19 to 26 km/h), and the threshold level for a full
deployment is about 18 to 24 mph (29 to 38.5 km/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 driver’s and right front passenger’s frontal
air bags are not designed to inate in rollovers, rear
impacts, or in many side impacts because ination
would not help the occupant.
The side impact air bags are designed to inate in
moderate to severe side crashes. A side impact air bag
will inate if the crash severity is above the system’s
designed “threshold level.” The threshold level can vary
with specic vehicle design. Side impact air bags are
not designed to inate in frontal or near-frontal impacts,
rollovers or rear impacts, because ination would not
help the occupant. A side impact air bag will only deploy
on the side of the vehicle that is struck.
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.
For frontal air bags, ination is determined by the angle
of the impact and how quickly the vehicle slows down
in frontal or near-frontal impacts. For side impact
air bags, ination is determined by the location and
severity of the impact.
1-57

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 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 and in the ceiling of
the vehicle, near the side windows.
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 the side
impact air bags.
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, the instrument panel for
the right front passenger’s bag or the ceiling of your
vehicle near the side windows — 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.
1-58

{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’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 inate 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 inate only once. After an
air bag inates, 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 may record 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.
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, or the side
impact air bag covering on the ceiling near the side
windows, 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 side impact air bag module and ceiling
covering for the roof-mounted 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 air bag system parts 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 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.
Air bag systems do 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 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.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 was not being used at the time of
the collision.
If your seat adjuster will not 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 will need to replace air bag
system parts. SeeAir Bag Systems on page 1-52.
If the frontal air bags inate, you will also need
to replace the driver’s and right front passenger’s safety
belt retractor assembly. Be sure to do so. Then the
new buckle assembly will be there to help protect you in
a collision.
After a crash you may need to replace the driver and
front passenger’s safety belt retractor assemblies, even
if the frontal air bags have not deployed. The driver
and 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 3-34.
