belt CADILLAC CTS 2009 2.G Service Manual

Here are the most important things to know about the
airbag system:
{CAUTION:
You can be severely injured or killed in a crash if
you are not wearing your safety belt — even if you
have airbags. Airbags are designed to work with
safety belts, but do not replace them. Also, airbags
are not designed to deploy in every crash. In some
crashes safety belts are your only restraint. See
When Should an Airbag Inflate? on page 1-63.
Wearing your safety belt during a crash helps
reduce your chance of hitting things inside the
vehicle or being ejected from it. Airbags are
“supplemental restraints” to the safety belts.
Everyone in your vehicle should wear a safety belt
properly — whether or not there is an airbag for
that person.
{CAUTION:
Airbags inate with great force, faster than the
blink of an eye. Anyone who is up against, or
very close to, any airbag when it inates can be
seriously injured or killed. Do not sit unnecessarily
close to the airbag, as you would be if you were
sitting on the edge of your seat or leaning forward.
Safety belts help keep you in position before and
during a crash. Always wear your safety belt,
even with airbags. The driver should sit as far
back as possible while still maintaining control of
the vehicle.
Occupants should not lean on or sleep against the
door or side windows in seating positions with
seat-mounted side impact airbags and/or roof-rail
airbags.
1-59

{CAUTION:
Children who are up against, or very close to, any
airbag when it inates can be seriously injured
or killed. Airbags plus lap-shoulder belts offer
protection for adults and older children, 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 1-34orInfants and Young Children on
page 1-37.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 3-36
for more information.
1-60

What Makes an Airbag Inate?
In a deployment event, the sensing system sends an
electrical signal triggering a release of gas from
the inator. Gas from the inator lls the airbag
causing the bag to break out of the cover and deploy.
The inator, the airbag, and related hardware are all
part of the airbag module.
Frontal airbag modules are located inside the steering
wheel and instrument panel. For vehicles with
seat-mounted side impact airbags, there are airbag
modules in the side of the front seatbacks closest to the
door. For vehicles with roof-rail airbags, there are
airbag modules in the ceiling of the vehicle, near the
side windows that have occupant seating positions.
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.
Airbags supplement the protection provided by safety
belts. Frontal airbags distribute the force of the impact
more evenly over the occupant’s upper body, stopping
the occupant more gradually. Seat-mounted side impact
and roof-rail airbags distribute the force of the impact
more evenly over the occupant’s upper body.
But airbags would not help in many types of collisions,
primarily because the occupant’s motion is not
toward those airbags. SeeWhen Should an Airbag
Inflate? on page 1-63for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.
1-65

The passenger sensing system turns off the right front
passenger frontal airbag under certain conditions.
The driver airbag, seat-mounted side impact airbags
and the roof-rail airbags are not affected by the
passenger sensing system.
The passenger sensing system works with sensors that
are part of the right front passenger seat. The sensors
are designed to detect the presence of a properly-seated
occupant and determine if the right front passenger
frontal airbag should be enabled (may inate) or not.
According to accident statistics, children are safer when
properly secured in a rear seat in the correct child
restraint for their weight and size.
We recommend that children be secured in a rear seat,
including: an infant or a child riding in a rear-facing
child restraint; a child riding in a forward-facing child
seat; an older child riding in a booster seat; and children,
who are large enough, using safety belts.
A label on the 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
airbag inates. This is because the back of the
rear-facing child restraint would be very close to the
inating airbag. A child in a forward-facing child
restraint can be seriously injured or killed if the right
front passenger airbag inates and the passenger
seat is in a forward position.
Even if the passenger sensing system has turned
off the right front passenger frontal airbag, no
system is fail-safe. No one can guarantee that
an airbag will not deploy under some unusual
circumstance, even though the airbag is turned off.
Secure rear-facing child restraints in a rear
seat, even if the airbag is off. If you 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.
1-68

The passenger sensing system is designed to turn off
the right front passenger airbag if:
The right front passenger seat is unoccupied.
The system determines an infant is present in a
child restraint.
A right front passenger takes his/her weight off of
the seat for a period of time.
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
right front passenger frontal airbag, the off indicator
will light and stay lit to remind you that the airbag is off.
SeePassenger Airbag Status Indicator on page 3-37.
The passenger sensing system is designed to turn
on (may inate) the right front passenger frontal airbag
anytime the system senses that a person of adult
size is sitting properly in the right front passenger 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, including children in child restraints,
and for very small adults, the passenger sensing
system may or may not turn off the right front passenger
frontal airbag, depending upon the person’s seating
posture and body build. Everyone in the vehicle who has
outgrown child restraints should wear a safety belt
properly — whether or not there is an airbag for that
person.
{CAUTION:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. SeeAirbag Readiness Light on page 3-36
for more information, including important safety
information.
1-69

If this happens, use the following steps to allow the
system to detect that person and enable the right front
passenger frontal airbag:
1. Turn the vehicle off.
2. Remove any additional material from the seat, such
as blankets, cushions, seat covers, seat heaters, or
seat massagers.
3. Place the seatback in the fully upright position.
4. Have the person sit upright in the seat, centered on
the seat cushion, with legs comfortably extended.
5. Restart the vehicle and have the person remain in
this position for two to three minutes after the on
indicator is lit.Additional Factors Affecting System
Operation
Safety belts help keep the passenger in position on the
seat during vehicle maneuvers and braking, which helps
the passenger sensing system maintain the passenger
airbag status. See “Safety Belts” and “Child Restraints” in
the Index for additional information about the importance
of proper restraint use.
A thick layer of additional material, such as a blanket
or cushion, or aftermarket equipment such as seat
covers, seat heaters, and seat massagers can affect
how well the passenger sensing system operates.
We recommend that you not use seat covers or other
aftermarket equipment except when approved by GM
for your specic vehicle. SeeAdding Equipment to
Your Airbag-Equipped Vehicle on page 1-73for more
information about modications that can affect how
the system operates.
1-71

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change the vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts
of the front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel, instrument
panel, roof-rail airbag modules, ceiling headliner
or pillar garnish trim, front sensors, or airbag wiring
can affect the operation of the airbag system.
In addition, the vehicle has a passenger sensing
system for the right front passenger position, which
includes sensors that are part of the passenger’s
seat. The passenger sensing system may not
operate properly if the original seat trim is replaced
with non-GM covers, upholstery or trim, or with
GM covers, upholstery or trim designed for a
different vehicle. Any object, such as an aftermarket
seat heater or a comfort enhancing pad or device,
installed under or on top of the seat fabric, could alsointerfere with the operation of the passenger sensing
system. This could either prevent proper deployment
of the passenger airbag(s) or prevent the passenger
sensing system from properly turning off the
passenger airbag(s). SeePassenger Sensing
System on page 1-67.
If you have any 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 7-2.
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: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.
In addition, your dealer/retailer and the service
manual have information about the location of the
airbag sensors, sensing and diagnostic module and
airbag wiring.

Restraint System Check
Checking the Restraint Systems
Safety Belts
Now and then, check the safety belt reminder light,
safety belts, buckles, latch plates, retractors, and
anchorages are all working properly.
Look for any other loose or damaged safety belt system
parts that might keep a safety belt system from doing
its job. See your dealer/retailer to 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.
Make sure the safety belt reminder light is working.
SeeSafety Belt Reminders on page 3-35for more
information.
Keep safety belts clean and dry. SeeCare of Safety
Belts on page 5-109.
Airbags
The airbag system does not need regularly scheduled
maintenance or replacement. Make sure the airbag
readiness light is working. SeeAirbag Readiness Light
on page 3-36for more information.
Notice:If an airbag covering is damaged, opened,
or broken, the airbag may not work properly.
Do not open or break the airbag coverings. If there
are any opened or broken airbag covers, have
the airbag covering and/or airbag module replaced.
For the location of the airbag modules, seeWhat
Makes an Airbag Inflate? on page 1-65. See your
dealer/retailer for service.
1-74

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 the vehicle has been in a crash, do you need new
safety belts or LATCH system (if equipped) parts?
After a very minor crash, nothing may be necessary.
But the safety belt assemblies that were used during any
crash may have been stressed or damaged. See your
dealer/retailer to have the safety belt assemblies
inspected or replaced.
If the vehicle has the LATCH system and it was being
used during a crash, you may need new LATCH
system parts.
New parts and repairs may be necessary even if the
safety belt or LATCH system (if equipped), was
not being used at the time of the crash.
If an airbag inates, you will need to replace airbag
system parts. See the part on the airbag system earlier
in this section.
Have the safety belt pretensioners checked if the
vehicle has been in a crash, if the airbag readiness light
stays on after the vehicle is started, or while you are
driving. SeeAirbag Readiness Light on page 3-36.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers, especially children, can easily
open the doors and fall out of a moving vehicle.
When a door is locked, the handle will not open
it. You increase the chance of being thrown out
of the vehicle in a crash if the doors are not
locked. So, wear safety belts properly and lock
the doors whenever you drive.
Young children who get into unlocked vehicles
may be unable to get out. A child can be
overcome by extreme heat and can suffer
permanent injuries or even death from heat
stroke. Always lock your vehicle whenever you
leave it.
Outsiders can easily enter through an unlocked
door when you slow down or stop your vehicle.
Locking your doors can help prevent this from
happening.There are several ways to lock and unlock the vehicle.
From the inside, use the manual lock levers located
on the door panels near the windows.
Push down on the manual lock lever to lock the door.
To unlock the door, pull up on the lever.
If the windows are down and the doors are locked,
do not reach in to manually unlock the vehicle because
you will set off the alarm.
From the outside, use the key, or press the lock or
unlock button on the Remote Keyless Entry (RKE)
transmitter. SeeRemote Keyless Entry (RKE) System
Operation on page 2-6for more information.
On vehicles with the Remote Keyless Access system,
the door unlocks by pulling the door handle when
you have the transmitter with you. SeeKeyless Access
System Operation on page 2-8for more information.
Central Door Unlocking System
The vehicle has a central door unlocking feature.
When unlocking the driver door, the other doors can be
unlocked by holding the key in the turned position for a
few seconds or by quickly turning the key twice in the
lock cylinder.
