2007 CHEVROLET OPTRA 5 ECU

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 airbag off symbol
will be visible near the
clock, located in the
center of the instrument
panel, during the
system check.
When the system check is complete, the airbag off
symbol will be visible under certain conditions.
SeePassenger Airbag Status Indicator on
page 165. The passenger sensing system will turn
off the right front passenger’s frontal airbag and
seat-mounted side impact airbag (if equipped)
under certain conditions. The driver’s airbags are
not part of the passenger sensing system.The passenger sensing system works with a
sensor that is part of the right front passenger’s
seat cushion. The sensor is designed to detect the
presence of a properly-seated occupant and
determine if the passenger’s frontal airbag and
seat-mounted side impact airbag (if equipped)
should be enabled (may inflate) 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 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.
76

{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 and side
impact airbag (if equipped) 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 or
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.
77

The passenger sensing system is designed to turn
off the right front passenger’s frontal airbag and
seat-mounted side impact airbag (if equipped) 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 (if equipped),
the off symbol near the clock will light and stay
lit to remind you that the airbag or airbags are off.
SeePassenger Airbag Status Indicator on
page 165.
If a child restraint has been installed and the off
symbol is not 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 62.
78

If, after reinstalling the child restraint and restarting
the vehicle, the off symbol is still not 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 off symbol is still not 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 inflate) the right front passenger’s
frontal airbag and seat-mounted side impact airbag
(if equipped) 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 or airbags
to be enabled, the off symbol will not light.
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 and side
airbag (if equipped), 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.
79

{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 and side airbag (if equipped).
SeeAirbag Readiness Light on page 164
for 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 83for
more information about modifications that can
affect how the system operates.
81

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 388.
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,
the instrument panel, 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 388.

One key is used for the
ignition, the doors and
all other locks.When a new vehicle is delivered, the dealer
removes the key tag and gives it to the first owner.
The tag has a code on it that tells your dealer
how to make extra keys. For vehicle security, keep
the key tag in a safe place and also record the
key number somewhere other than inside of
the vehicle. If you lose your key, you will be able
to have a new one made easily using the tag.
If you need a new key, contact your dealer who
can obtain the correct key code. SeeRoadside
Assistance Program on page 394for more
information.
Notice:If you ever lock your keys in your
vehicle, you may have to damage the vehicle
to get in. Be sure you have spare keys.
