2008 CHEVROLET AVEO ECU

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 1-52.
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. SeeHead
Restraints on page 1-6.
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 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/retailer.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 seat-mounted side impact 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.
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, turn the vehicle off, remove any additional
material from the seat, such as blankets, cushions,
seat covers, seat heaters or seat massagers 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.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about 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. Changing or moving any parts
of the front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel, instrument
panel, front sensors, or airbag wiring can affect
the operation of the airbag system.
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 1-65.
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.
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: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. See
Customer Satisfaction Procedure on page 7-2.
In addition, your dealer/retailer and the service manual
have information about the location of the airbag
sensors, sensing and diagnostic module and airbag
wiring.

Keys
{CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons, children
or others could be badly injured or even killed.
They could operate the power windows or
other controls or even make the vehicle move.
The windows will function with the keys in the
ignition and they could be seriously injured
or killed if caught in the path of a closing
window. Do not leave the keys in a vehicle
with children.
One key is used for the ignition, the doors and all
other locks.
When a new vehicle is delivered, the dealer/retailer
removes the key tag and gives it to the first owner.
The tag has a code on it that tells your dealer/retailer
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.

being started by unauthorized persons.
The system is automatically armed when the key is
removed from the ignition.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
