Index
To quickly locate information about
the vehicle use the Index in the
back of the manual. It is an
alphabetical list of what is in the
manual and the page number where
it can be found.
Cautions and Notices
There are a number of safety
cautions in this book. A box with the
word CAUTION is used to tell
about things that could cause injury
if the warning is ignored.
{CAUTION
These mean there is something
that could hurt you or other
people.
Cautions tell what the hazard is and
what to do to avoid or reduce the
hazard. Read these cautions.A circle with a slash through it is a
safety symbol which means “Do Not,”
“Do Not do this” or “Do Not let this
happen.”
Notices are also used in this
manual.
Notice:These mean there is
something that could damage
your vehicle.
A notice tells about something that
can damage the vehicle. Many
times, this damage would not be
covered by the vehicle’s warranty,
and it could be costly. The notice
tells what to do to help avoid
the damage.There are also warning labels on
the vehicle which use the same
words, CAUTION or NOTICE.
Other manuals may use CAUTION
and NOTICE warnings in different
colors or in different words.
Vehicle Symbols
The vehicle has components and
labels that use symbols instead
of text. Symbols are shown along
with the text describing the operation
or information relating to a specic
component, control, message,
gage, or indicator.
Preface iii
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.

Matching Transmitter(s) to
Your Vehicle
Each RKE transmitter is coded to
prevent another transmitter from
unlocking your vehicle. If a
transmitter is lost or stolen, a
replacement can be purchased
through your dealer/retailer. Bringany additional transmitters so they
can also be re-coded to match
the new transmitter. Once your
dealer/retailer has coded the new
transmitter, the lost transmitter
will not unlock your vehicle.
Battery Replacement
The RKE transmitter has a lithium
battery which should last about
three years.
Have the battery replaced if the
Replace Battery in Remote
Key message displays in the DIC or
if the transmitter will not work at
the normal range in any location.
See “Replace Battery in Remote
Key” underDIC Warnings and
Messages on page 4-27.
