2006 CHEVROLET OPTRA 5 ECU

{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 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. General Motors recommends 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.The passenger sensing system is designed to turn off
the right front passenger’s frontal airbag and side 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
passenger’s frontal airbag and side airbag (if equipped),
the off symbol near the clock will light and stay lit to
remind you that the airbag or airbags are off. See
Passenger Airbag Status Indicator on page 3-31.
1-61

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 to
Securing a Child Restraint in the Right Front Seat
Position on page 1-48.
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 side 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), dependingupon 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 symbol is lit, it could be
because that person is not sitting properly in the seat. If
this happens do one of the following:
•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 three minutes. This will allow the
system to detect that person and then enable
the passenger’s airbag or airbags.
•Take the right front passenger’s weight off of the
seat for more than three seconds, place the
seatback in the fully upright position, and then sit
upright in the seat, centered on the seat cushion,
with the person’s legs comfortably extended.
Have the person remain in this position for about
3 minutes. This will allow the system to detect
that person and then enable the passenger’s airbag
or airbags.

{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 3-30for 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 1-64for more information about modifications that
can affect how the system operates.
1-63

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
inflate 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 7-15.
{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.
1-64

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 (located under the right front passenger’s
seat), or the instrument panel 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.
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 frontal airbag, or
an airbag covering (if equipped) on a seatback, the
airbag 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 frontal airbag, or both
the airbag module and the seatback for seating
positions with a side impact airbag (if equipped.) Do
not open or break the airbag coverings.

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
