ECU CADILLAC DTS PROFESSIONAL 2006 1.G Owner's Manual

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.
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.
To remove the child restraint, just unbuckle the vehicle’s
safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for an
adult or larger child passenger.Airbag System
Your vehicle has the following airbags:
a frontal airbag for the driver and another frontal
airbag for the right front passenger, and
a seat-mounted side impact airbag for the driver
and another for the right front passenger.
Your vehicle may also have the following airbags:
a roof-mounted side impact airbag for the driver and
passenger directly behind the driver, and
a roof-mounted side impact airbag for the right front
passenger and the person seated directly behind
that passenger.
Frontal airbags are designed to help reduce the risk of
injury from the force of an inating airbag. But these
airbags must inate very quickly to do their job
and comply with federal regulations.
1-54

{CAUTION:
Both frontal and side impact airbags inate
with great force, faster than the blink of an
eye. If you are too close to an inating airbag,
as you would be if you were leaning forward, it
could seriously injure you. Safety belts help
keep you in position for airbag ination before
and during a crash. Always wear your safety
belt even with frontal 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.
{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 1-30orInfants and
Young Children on page 1-33.
1-56

If your vehicle has one, 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. If your vehicle has
roof-mounted side impact airbags, 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.
1-60

The passenger sensing system works with sensors that
are part of the right front passenger’s seat and safety
belt. The sensors are designed to detect the presence of
a properly-seated occupant and determine if the right
front passenger’s frontal airbag and seat-mounted
side impact 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.
General Motors recommends 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 right front passenger’s
frontal and seat-mounted side impact 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 airbags are 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.
1-66

The passenger sensing system is designed to turn off
the right front passenger’s frontal airbag and
seat-mounted side impact 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
right front passenger’s frontal airbag and seat-mounted
side impact airbag, the off indicator will light and
stay lit to remind you that the airbags are off.
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 1-51.
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.

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.
1-70

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 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. SeeCare of Safety Belts on
page 5-86for 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 (if
equipped) 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 (if
equipped). Do not open or break the airbag
coverings.
