ECU CADILLAC STS 2007 1.G Owner's Manual

{CAUTION:
Anyone who is up against, or very close to,
any airbag when it inates can be seriously
injured or killed. Airbags plus lap-shoulder
belts offer the best protection for adults,
but not for young children and infants.
Neither the vehicle’s safety belt system nor
its airbag system is designed for them.
Young children and infants need the
protection that a child restraint system can
provide. Always secure children properly
in your vehicle. To read how, seeOlder
Children on page 38orInfants and Young
Children on page 40.
There is an airbag
readiness light on the
instrument panel cluster,
which shows the
airbag symbol.The system checks the airbag electrical system for
malfunctions. The light tells you if there is an
electrical problem. SeeAirbag Readiness Light on
page 244for more information.
Where Are the Airbags?
The driver’s frontal airbag is in the middle of the
steering wheel.
66

The roof-mounted side impact airbag for the right
front passenger and the person seated directly
behind that passenger is in the ceiling above the
side windows.
{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.
69

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 245.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.
United StatesCanada
74

{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.
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.
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 245.
75

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 toSecuring a
Child Restraint in the Right Front Seat Position
on page 59.
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.
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.
76

{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.
CAUTION: (Continued)
CAUTION: (Continued)
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. See
Airbag Readiness Light on page 244for
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 79for
more information about modications that can
affect how the system operates.
77

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 526.
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. SeeCustomer
Satisfaction Procedure on page 526.
