2004 BUICK REGAL Owner's Manual

When Should an Air Bag Inate?
The driver’s and right front passenger’s frontal air bags
are designed to inate 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.”
If the front of your vehicle goes straight into a wall that
does not move or deform, the threshold level is
about 12 to 18 mph (19 to 29 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.
Your vehicle may or may not have a driver’s side impact
air bag. SeeAir Bag Systems on page 1-46. A driver
’s side impact air bag is designed to inate in moderate
to severe side crashes involving the driver’s door. 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. A
driver’s side impact air bag is not designed to inate
in frontal or near-frontal impacts, rollovers or rear
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.
For frontal air bags, ination 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, ination 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 the 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. Frontal air
bag modules are located inside the steering wheel
and instrument panel. For vehicles with a driver’s side
impact air bag, the air bag modules are located in
the seatback closest to the driver’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. A side impact air bag
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 that air bag. 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
side impact air bag.
What Will You See After an Air Bag
Inates?
After the 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, 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
deated air bags. Air bag ination does not prevent
the driver from seeing or being able to steer the vehicle,
nor does it stop people from leaving the vehicle.
1-52

{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 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.
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
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
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 the air
bag covering on the driver’s 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 the driver’s 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 7-11.
{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
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.
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 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 wasn’t being used at the time of
the collision.
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.
