ECU CADILLAC CTS 2006 1.G Owner's 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 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.

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 you turn your ignition
key to ON or START. The words ON and OFF or the
symbol for on and off, will be visible on the rearview
mirror 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 3-35.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.
There is a critical problem with the airbag system
or the passenger sensing system.
1-64

When the passenger sensing system has turned off
the passenger’s frontal airbag, the off indicator in
the rearview mirror will light and stay lit to remind you
that the airbag is off. SeePassenger Airbag Status
Indicator on page 3-35.
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 1-50.
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.
1-65

{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 3-34for 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 1-68for more information about modications
that can affect how the system operates.
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 7-16.
{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, front end or side sheet
metal or height, 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.
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, the inside rearview mirror, steering wheel,
ceiling headliner, ceiling and pillar garnish trim,
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 7-2.

Programmable Automatic
Door Locks
If your vehicle has an automatic transmission, the
vehicle is programmed so that the doors will lock
automatically when all doors are closed, the ignition
is on, and the shift lever is moved out of PARK (P). The
doors will automatically unlock when you stop the
vehicle and move the shift lever back into PARK (P).
If your vehicle has a manual transmission, the vehicle is
programmed so that the doors will lock automatically
after the vehicle speed reaches 5 mph (8 km). The doors
will automatically unlock when the ignition is turned
off and the key is removed from the ignition.
If someone needs to exit the vehicle once the doors
are locked, have that person use the manual lever
or power door lock switch. When the door is closed
again, it will not lock automatically. Use the manual lever
or the power door lock switch to lock the door.
The power door locks can be programmed through
prompts displayed on the Driver Information
Center (DIC). These prompts allow you to choose
various lock and unlock settings. For more information
on programming, seeDIC Vehicle Personalization
on page 3-70.
