CADILLAC STS 2006 1.G Repair Manual

{CAUTION:
If something is between an occupant and an
airbag, the airbag 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. Never secure anything to the
roof of your vehicle by routing the rope or
tie-down through any door or window opening.
If you do, the path of an inating airbag will
be blocked. Do not let seat covers block the
ination path of a side impact airbag. 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 has electronic frontal sensors, 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.
1-55

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 12 to 16 mph
(19 to 26 km/h), and the threshold level for a full
deployment is about 18 to 24 mph (28.5 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.
Frontal airbags may inate at different crash speeds.
For example:
If the vehicle hits a stationary object, the airbags
could inate at a different crash speed than if the
vehicle hits a moving object.
If the vehicle hits an object that deforms, the
airbags could inate at a different crash speed than
if the vehicle hits an object that does not deform.
If the vehicle hits a narrow object (like a pole) the
airbags 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
airbags 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.
The side impact airbags are intended 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
intended to inate in frontal or near-frontal impacts,
rollovers or rear impacts. A side impact airbag is intended
to 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 what the vehicle
hits, 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.
1-56

What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash. 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 many
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 frontal and seat-mounted side impact airbags
inate, they quickly deate, so quickly that some people
may not even realize the airbags inated. Roof-mounted
side impact airbags are designed to deate more slowly
and may still be at least partially inated minutes after
the vehicle comes to rest. 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 — may be hot for a short time. The parts of
the airbag that come into contact with you may be warm,
but not too hot to touch.
1-57

There will be some smoke and dust coming from the
vents in the deated airbags. Airbag ination does
not prevent the driver from seeing out of the windshield
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 may automatically unlock
the doors, turn the interior lamps on, turn the hazard
warning ashers on, and turn off the climate control
system when the airbags inate.You can lock the doors, turn the interior lamps off, turn
the hazard warning ashers off, and turn the climate
control system on by using the controls for those
features.
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 has 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.

Passenger Sensing System
Your vehicle has a passenger sensing system for the
right front passenger position. The passenger airbag
status indicator will be visible when the vehicle is
running. The words ON and OFF or the symbol for on
and off, will be visible in the overhead console during the
system check. When the system check is complete,
either the word ON or the word OFF, or the symbol for
on or the symbol for off will be visible. SeePassenger
Airbag Status Indicator on page 3-61.
The passenger sensing system will turn off the right
front passenger’s frontal airbag under certain conditions.
The driver’s airbags are not part of the passenger
sensing system.The passenger sensing system works with sensors
that are part of the right front passenger’s seat.
The sensors are designed to detect the presence of
a properly-seated occupant and determine if the
passenger’s frontal airbag should be enabled (may
inate) or not.
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
We recommend that child restraints be secured in a
rear seat, including an infant riding in a rear-facing infant
seat, a child riding in a forward-facing child seat and
an older child riding in a booster seat.

Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun visor
says, “Never put a rear-facing child seat in the
front.” This is because the risk to the rear-facing child
is so great, if the airbag deploys.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating airbag.
Even though the passenger sensing system is
designed to turn off the passenger’s frontal
airbag if the system detects a rear-facing child
restraint, no system is fail-safe, and no one
can guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend that
rear-facing child restraints be secured in the
rear seat, even if the airbag is off.
CAUTION: (Continued)
CAUTION: (Continued)
If you need to secure a forward-facing child
restraint in the right front seat, always move
the front passenger seat as far back as it will
go. It is better to secure the child restraint in a
rear seat.
The passenger sensing system is designed to turn off
the right front passenger’s frontal airbag if:
the right front passenger seat is unoccupied
the system determines that an infant is present in a
rear-facing infant seat
the system determines that a small child is present
in a forward-facing child restraint
the system determines that a small child is present
in a booster seat
a right front passenger takes his/her weight off of
the seat for a period of time
the right front passenger seat is occupied by a
smaller person, such as a child who has outgrown
child restraints
or if there is a critical problem with the airbag
system or the passenger sensing system.
1-60

When the passenger sensing system has turned off
the passenger’s frontal airbag, the off indicator in
the overhead console will light and stay lit to remind
you that the airbag is off. SeePassenger Airbag Status
Indicator on page 3-61.
If a child restraint has been installed and the on indicator
is lit, turn the vehicle off. Remove the child restraint from
the vehicle and reinstall the child restraint following the
child restraint manufacturer’s directions and refer to
Securing a Child Restraint in the Right Front Seat
Position on page 1-46.
If after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the child
restraint into the seat cushion. If this happens, slightly
recline the vehicle’s seatback and adjust the seat
cushion if possible. Also make sure the child restraint
is not trapped under the vehicle head restraint. If
this happens, adjust the head restraint.
If the on indicator is still lit, secure the child in the
child restraint in a rear seat position in the vehicle and
check with your dealer.The passenger sensing system is designed to enable
(may inate) the right front passenger’s frontal airbag
anytime the system senses that a person of adult size is
sitting properly in the right front passenger’s seat. When
the passenger sensing system has allowed the airbag to
be enabled, the on indicator will light and stay lit to remind
you that the airbag is active.
For some children who have outgrown child restraints
and for very small adults, the passenger sensing system
may or may not turn off the right front passenger’s
frontal airbag, depending upon the person’s seating
posture and body build. Everyone in your vehicle who
has outgrown child restraints should wear a safety
belt properly — whether or not there is an airbag for
that person.
1-61

If a person of adult-size is sitting in the right front
passenger’s seat, but the off indicator is lit, it could be
because that person is not sitting properly in the seat. If
this happens, turn the vehicle off and ask the person to
place the seatback in the fully upright position, then sit
upright in the seat, centered on the seat cushion, with the
person’s legs comfortably extended. Restart the vehicle
and have the person remain in this position for about
two minutes. This will allow the system to detect that
person and then enable the passenger’s airbag.
{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on,
it means that something may be wrong with
the airbag system. If this ever happens, have
the vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger’s seat may not have the protection
of the frontal airbag. SeeAirbag Readiness
Light on page 3-60for more on this, including
important safety information.
A thick layer of additional material such as a blanket,
or aftermarket equipment such as seat covers, seat
heaters and seat massagers can affect how well
the passenger sensing system operates. Remove
any additional material from the seat cushion before
reinstalling or securing the child restraint or small
occupant. You may want to consider not using seat
covers or other aftermarket equipment if your vehicle
has the passenger sensing system. SeeAdding
Equipment to Your Airbag-Equipped Vehicle on
page 1-63for more information about modications
that can affect how the system operates.
1-62

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. You do not 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 airbag system. To
purchase a service manual, seeService Publications
Ordering Information on page 7-14.
{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 close to an airbag
when it inates. Avoid yellow connectors. They
are probably part of the airbag system. 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.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Also, the airbag system may not
work properly if you relocate any of the airbag
sensors. If you have any questions about this, you
should contact Customer Assistance before you
modify your vehicle. The phone numbers and
addresses for Customer Assistance are in Step Two
of the Customer Satisfaction Procedure in this
manual. SeeCustomer Satisfaction Procedure
on page 7-2.
1-63

Q:Because I have a disability, I have to get my
vehicle modied. How can I nd out whether
this will affect my airbag system?
A:Changing or moving any parts of the front seats,
safety belts, the airbag sensing and diagnostic
module, steering wheel, instrument panel, overhead
console, ceiling headliner, ceiling and pillar garnish
trim, roof-mounted airbag modules, or airbag wiring
can affect the operation of the airbag system. If you
have questions, call Customer Assistance. The
phone numbers and addresses for Customer
Assistance are in Step Two of the Customer
Satisfaction Procedure in this manual. See
Customer Satisfaction Procedure on page 7-2.
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. Keep safety belts clean and dry.
SeeCare of Safety Belts on page 5-97for more
information.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.)
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.
