2007 CADILLAC STS ECU

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.

{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.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some
cities. Although your vehicle has a number of
theft-deterrent features, we know that nothing
we put on it can make it impossible to steal.
107

Theft-Deterrent System
Your vehicle has a theft-deterrent alarm system.
The security light is
located on the
instrument panel cluster.
If the ignition is off and a door is open, the
security light will ash, reminding you to arm
the theft-deterrent system.
To arm the system, do one of the following:
Press the lock button on the keyless access
transmitter. If the door is closed when the
lock button is pressed, the security light
will stay illuminated for 30 seconds. After the
security light goes off, the theft-deterrent
system is armed. Pressing the lock button
twice will arm the system immediately.
If the vehicle is locked using the keyless
access transmitter and the trunk lid, hood
or a door is open or not closed completely,the security light will ash for 60 seconds and
then turn off. At this time, the theft-deterrent
system is armed but the alarm will not sound if
the trunk lid, hood or door that was not
closed completely is tampered with or opened.
The alarm will sound for the trunk lid, hood
or a door that was completely closed at
the time the vehicle was locked using the
keyless access transmitter.
Open the door. Lock the door with the power
door lock switch or lock button on the keyless
access transmitter. The security light should
ash. Close the door. The security light
will stop ashing and stay on. After 30 seconds
the light should turn off, the theft-deterrent
system is armed.
Passive Arming, if activated through the
vehicle personalization feature, will arm
the system automatically after you close the
door and take at least one keyless access
transmitter with you. The security light will turn
on. After 60 seconds the light should turn
off. The theft-deterrent system is armed. See
Vehicle Personalization on page 148.
