ECU CHEVROLET EPICA 2006 1.G Owner's Manual

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 3-33.
The passenger sensing system will turn off the
right front passenger’s frontal airbag and side airbag
(if equipped) under certain conditions. The driver’s
frontal airbag and side airbag (if equipped) 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 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. General Motors recommends 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 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.
1-58

{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 3-33.
1-59

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 1-46.
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), 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 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
three minutes. This will allow the system to
detect that person and then enable the passenger’s
airbag or airbags.
1-60

{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 3-32for 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 1-62for more information about modifications
that can affect how the system operates.
1-61

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 7-14.
{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.
1-62

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.

Section 2 Features and Controls
2-1

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.
Your vehicle may have an electronic immobilizer
designed to protect your car against theft. If so, only
keys with the correct electronic code can be used
to start the vehicle. Even if a key has the same profile,
it will not start the engine if the electronic code is
incorrect. If you need a new key, contact your dealer
who can obtain the correct key code. SeeRoadside
Assistance Program on page 7-6for more information.Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
