SATURN ION 2004 Repair 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.”
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 does not move or deform, the threshold level
for the reduced deployment is about 16 to 20 mph
(26 to 32 km/h), and the threshold level for a full
deployment is 25 to 30 mph (40 to 48 hm/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 with 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.
It is possible that, in a crash involving the front of your
vehicle, only one of the two frontal air bags in your vehicle
will deploy. This is rare, but it can happen in a crash just
severe enough to make a frontal air bag inate.
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
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. For vehicles with side impact air
bags, the air bag modules are located 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 frontalor 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 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.

{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.
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 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.
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 retailer
and the Saturn Service Manual have information
about servicing your vehicle and the air bag systems.
To purchase a service manual, seeService Publications
Ordering Information on page 7-10.
{CAUTION:
For up to one minute 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, yellow coverings, or
yellow connectors. They are probably part of
the air bag systems. 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.
Adding Equipment to Your
Air Bag-Equipped Vehicle
Q:If I add a luggage carrier or sunroof to the roof
of my vehicle, will it keep the roof-mounted side
impact air bags from working properly?
A:As long as the luggage carrier or sunroof is
properly installed so that the vehicle’s basic
structure isn’t changed, it’s not likely to keep the
roof-mounted side impact air bags from working
properly in a crash.

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.
1-59
ProCarManuals.com

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. See the part about the air bag system
earlier in this manual.If the frontal air bags inate you will need to replace the
driver’s and right front passengers safety belt retractor
assembly. Be sure to do so. Then the new retractor
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.
