ECU CADILLAC STS 2009 1.G Owner's Manual

{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 1-28
orInfants and Young Children on page 1-31.
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 3-58
for more information.
Where Are the Airbags?
The driver’s frontal airbag is in the middle of the
steering wheel.
1-53

The roof-rail airbags for the driver, right front passenger,
and second row outboard passengers are 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.
Do not use seat accessories that block the ination
path of a seat-mounted side impact airbag.
Never secure anything to the roof of a vehicle with
roof-rail airbags by routing a rope or tie down
through any door or window opening. If you do, the
path of an inating roof-rail airbag will be blocked. Driver Side shown, Passenger Side similar
1-55

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 right front 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 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 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
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 it 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.
1-60

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 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, the off indicator
will light and stay lit to remind you that the airbag is off.
SeePassenger Airbag Status Indicator on page 3-59.
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 followingthe child restraint manufacturer’s directions and refer to
Securing a Child Restraint in the Right Front Seat
Position on page 1-47.
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. SeeHead Restraints on page 1-5.
Remove any additional material from the seat such as
blankets, cushions, seat covers, seat heaters, or seat
massagers before reinstalling or securing the child
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/retaier.
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.
1-61

In addition, your vehicle has a passenger sensing
system for the right front passenger’s 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 also
interfere 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 1-59.
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.

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. 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.
Exit the vehicle and 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

If Passive Arming is activated through the vehicle
personalization feature, the system will arm
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.
SeeVehicle Personalization on page 2-61.
If a door, hood, or the trunk is opened without the
keyless access transmitter, the horn will sound for
30 seconds and the lamps will ash for two minutes.
The vehicle cannot be started without a keyless access
transmitter.
The Theft-Deterrent system will not arm if:
The key is used to turn the key cylinder to the lock
position.
The driver’s door is locked using the power door
lock switch after the doors are closed.
