2005 CADILLAC STS Owners Manual

{CAUTION:
If something is between an occupant and an
airbag, 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 airbag must be kept clear. Do not put
anything between an occupant and an airbag,
and do not attach or put anything on the
steering wheel hub or on or near any other
airbag covering. And, because your vehicle
has side impact airbags, 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 airbag will be blocked. The path
of an inating airbag must be kept clear.

When Should an Airbag Inate?
The driver’s and right front passenger’s frontal airbags
are designed to inate in moderate to severe frontal
or near-frontal crashes. But they are designed to inate
only if the impact exceeds a predetermined deployment
threshold. Deployment thresholds take into account
a variety of desired deployment and non-deployment
events and are used to predict how severe a crash
is likely to be in time for the airbags to inate and help
restrain the occupants. Whether your frontal airbags
will or should deploy is not based on how fast your
vehicle is traveling. It depends largely on what you hit,
the direction of the impact and how quickly your
vehicle slows down.
In addition, your vehicle has “dual stage” frontal airbags,
which adjust the restraint according to crash severity.
Your vehicle is equipped with an electronic frontal sensor,
which helps the sensing system distinguish between a
moderate frontal impact and a more severe frontal
impact. For moderate frontal impacts, these airbags
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 11 to 15 mph (18 to 24 km/h),and the threshold level for a full deployment is about
20 to 24 mph (32 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.)
Airbags may inate at different crash speeds. For
example:
If the vehicle hits a stationary object, the airbag
could inate at a different crash speed than if
the object were moving.
If the object deforms, the airbag could inate at
a different crash speed than if the object does
not deform.
If the vehicle hits a narrow object (like a pole) the
airbag could inate at a different crash speed
than if the vehicle hits a wide object (like a wall).
If the vehicle goes into an object at an angle the
airbag could inate at a different crash speed
than if the vehicle goes straight into the object.
The frontal airbags (driver and right front passenger)
are not intended to inate during vehicle rollovers, rear
impacts, or in many side impacts because ination
would not likely help the occupants.
1-52

The side impact airbags are designed to inate in
moderate to severe side crashes. A side impact airbag
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 airbags are
not designed to inate in frontal or near-frontal impacts,
rollovers or rear impacts, because ination would not
likely help the occupant. A side impact airbag will
only deploy on the side of the vehicle that is struck.
In any particular crash, no one can say whether
an airbag should have inated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, 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 airbags, ination is determined by the location
and severity of the impact.
What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash. For both
frontal and side impact airbags, the sensing system
triggers a release of gas from the inator, which inates
the airbag. The inator, airbag and related hardware are
all part of the airbag modules inside the steering wheel,
instrument panel, the side of the front seatbacks closest
to the door and the ceiling of the vehicle, near the side
windows.
How Does an Airbag 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 airbag supplements the protection
provided by safety belts. Airbags distribute the force of
the impact more evenly over the occupant’s upper
body, stopping the occupant more gradually. But the
frontal airbags 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 airbag. Side impact airbags 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 airbags. Airbags 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 airbags, and only in moderate to severe
side collisions for side impact airbags.

What Will You See After an Airbag
Inates?
After the airbag inates, it quickly deates, so quickly that
some people may not even realize the airbag inated.
Some components of the airbag module — the steering
wheel hub for the driver’s airbag, the instrument panel for
the right front passenger’s bag, the side of the seatback
closest to the door for the seat-mounted side impact
airbags and the area along 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 airbags.
Airbag ination 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 airbag 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
cannot get out of the vehicle after an airbag
inates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an airbag deployment, you
should seek medical attention.
Your vehicle has a feature that will automatically unlock
the doors and turn the interior lamps on when the
airbags inate (if battery power is available). You can
lock the doors again and turn the interior lamps off
by using the door lock and interior lamp controls. The
hazard warning ashers will also come on when
the airbags deploy. If you want to turn them off, press
the hazard warning asher button twice.
1-54

In many crashes severe enough to inate the airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger airbag.
Airbags are designed to inate only once. After an
airbag inates, you will need some new parts for
your airbag system. If you do not get them,
the airbag system will not be there to help protect
you in another crash. A new system will include
airbag 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 after
a crash. SeeVehicle Data Collection and Event
Data Recorders on page 7-8.
Let only qualied technicians work on your airbag
system. Improper service can mean that an
airbag 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 airbag, or the airbag
covering on the driver’s and right front passenger’s
seatback, or the side impact airbag covering on
the ceiling near the side windows, the bag may not
work properly. You may have to replace the
airbag module in the steering wheel, both the airbag
module and the instrument panel for the right
front passenger’s airbag, the airbag module and
seatback for the driver’s and right front passenger’s
seat-mounted side impact airbags, or side impact
airbag module and ceiling covering for the
roof-mounted side impact airbag. Do not open or
break the airbag coverings.

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the
airbag system. To purchase a service manual, see
Service 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
airbag can still inate during improper service.
You can be injured if you are too close to an
airbag when it inates. Avoid wires wrapped
with yellow tape, yellow coverings or yellow
connectors. They are probably part of the
airbag systems. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualied to do so.
The airbag system does not need regular maintenance.
Restraint System Check
Checking the 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 airbag covers, and
have them repaired or replaced. (The airbag 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 an airbag inates, you will need to replace airbag
system parts. See the part on the airbag system earlier
in this section.
If the frontal airbags inate, you will also need to
replace the driver’s and right front passenger’s safety
belt buckle 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 buckle assemblies, even
if the frontal airbags have not deployed. The driver and
front passenger’s safety belt buckle assemblies
contain the safety belt pretensioners. Have your safety
belt pretensioners checked if your vehicle has been
in a collision, or if your airbag readiness light stays on
after you start your vehicle or while you are driving.
SeeAirbag Readiness Light on page 3-63.
