2008 - Pontiac G8 Owner Manual

The parts of the airbag that come
into contact with you may be warm,
but not too hot to touch. There may
be some smoke and dust coming
from the vents in the deated
airbags. Airbag ination does not
prevent the driver from seeing out of
the windshield or being able to steer
the vehicle, nor does it prevent
people from leaving the vehicle.
{CAUTION
When an airbag inates, there
may be dust in the air. This
dust could cause breathing
problems for people with a
history of asthma or other
breathing trouble. To avoid this,
everyone in the vehicle should
get out as soon as it is safe to
do so. If you have breathing
(Continued)
CAUTION (Continued)
problems but cannot get out of
the vehicle after an airbag
inates, then get fresh air by
opening a window or a door.
If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors,
turn the interior lamps on, and turn
the hazard warning ashers on
when the airbags inate. You can
lock the doors, turn the interior
lamps off, and turn the hazard
warning ashers off by using the
controls for those features.
In many crashes severe enough to
inate the airbag, windshields
are broken by vehicle deformation.Additional windshield breakage may
also occur from the right front
passenger airbag.Airbags are designed to inate
only once. After an airbag
inates, you will need some new
parts for the airbag system. If
you do not get them, the airbag
system will not be there to
help protect you in another crash.
A new system will include
airbag modules and possibly
other parts. The service manual
for your vehicle covers the
need to replace other parts.
The vehicle has a crash sensing
and diagnostic module which
records information after a crash.
SeeVehicle Data Recording and
Privacy on page 12-16andEvent
Data Recorders on page 12-16.
Let only qualied technicians work
on the airbag systems. Improper
service can mean that an airbag
system will not work properly. See
your dealer/retailer for service.

2008 - Pontiac G8 Owner Manual

{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 airbag(s).
SeeAirbag Readiness Light on
page 4-13for more on this,
including important safety
information.A thick layer of additional material,
such as a blanket or cushion, or
aftermarket equipment such as seat
covers, seat heaters, and seat
massagers can affect how well the
passenger sensing system
operates. We recommend that you
not use seat covers or other
aftermarket equipment other than
any that GM has approved for your
specic vehicle. SeeAdding
Equipment to Your Airbag-Equipped
Vehicle on page 1-30for more
information about modications
that can affect how the system
operates.The passenger sensing system may
suppress the airbag deployment
when liquid soaks into the seat.
If this happens, the off indicator in
the passenger airbag status
indicator and the airbag readiness
light on the instrument panel
will be lit. The system should
resume normal operation after the
seat is allowed to dry. If the
system operates incorrectly after
the seat has dried, have your
dealer/retailer check the system.
{CAUTION
Stowing of articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the
passenger sensing system.

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. Your
dealer/retailer 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 12-15.
{CAUTION
For up to 10 seconds after the
ignition 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.
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 the 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, roof-rail airbag modules,
the inside rearview mirror, ceiling
headliner or pillar garnish trim,
front sensors, or airbag wiring can
affect the operation of the airbag
system.
1-30 Seats and Restraints
2008 - Pontiac G8 Owner Manual

In addition, the vehicle has a
passenger sensing system for the
right front passenger 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 1-26.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 12-1.
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. SeeCustomer
Satisfaction Procedure on
page 12-1.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.
Airbag System Check
The airbag system does not need
regularly scheduled maintenance or
replacement. Make sure the
airbag readiness light is working.
SeeAirbag Readiness Light
on page 4-13for more information.
Notice:If an airbag covering
is damaged, opened, or broken,
the airbag may not work properly.
Do not open or break the airbag
coverings. If there are any opened
or broken airbag covers, have
the airbag covering and/or airbag
module replaced. For the
location of the airbag modules,
seeWhat Makes an Airbag
Inflate? on page 1-24. See your
dealer/retailer for service.

Replacing Airbag System
Parts After a Crash
{CAUTION
A crash can damage the airbag
systems in your vehicle.
A damaged airbag system
may not work properly and
may not protect you and your
passenger(s) in a crash,
resulting in serious injury or
even death. To help make sure
your airbag systems are
working properly after a crash,
have them inspected and any
necessary replacements made
as soon as possible.If an airbag inates, you will need to
replace airbag system parts. See
your dealer/retailer for service.
If the airbag readiness light stays on
after the vehicle is started or comes
on when you are driving, the
airbag system may not work
properly. Have the vehicle serviced
right away. SeeAirbag Readiness
Light on page 4-13for more
information.
