2009 Pontiac G8 Owner ManualM

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 1-25. 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.

Malfunction
Indicator Lamp
Check Engine Light
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the fuel, ignition, and emission
control systems. It ensures
that emissions are at acceptable
levels for the life of the vehicle,
helping to produce a cleaner
environment.
This light comes on when the ignition
is on, but the engine is not running,
as a check to show it is working. If it
does not, have the vehicle serviced
by your dealer/retailer.If the check engine light comes on
and stays on, while the engine
is running, this indicates that there
is an OBD II problem and service
is required.
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage to
the vehicle. This system assists the
service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is
continually driven with this light
on, after a while, the emission
controls might not work as well,
the vehicle’s fuel economy
might not be as good, and the
engine might not run as
smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.Notice:Modications made to
the engine, transmission, exhaust,
intake, or fuel system of the
vehicle or the replacement of the
original tires with other than those
of the same Tire Performance
Criteria (TPC) can affect the
vehicle’s emission controls and
can cause this light to come on.
Modications to these systems
could lead to costly repairs not
covered by the vehicle warranty.
This could also result in a failure
to pass a required Emission
Inspection/Maintenance test.
SeeAccessories and
Modifications on page 9-3.
4-18 Instruments and Controls

Emissions Inspection and
Maintenance Programs
Some state/provincial and local
governments have or might begin
programs to inspect the emission
control equipment on the vehicle.
Failure to pass this inspection could
prevent getting a vehicle registration.
Here are some things to know to
help the vehicle pass an inspection:
The vehicle will not pass this
inspection if the check engine
light is on with the engine
running, or if the key is in the
ON/RUN and the light is
not on.
The vehicle will not pass this
inspection if the OBD II
(on-board diagnostic) system
determines that critical emission
control systems have not
been completely diagnosed by
the system. The vehicle would
be considered not ready forinspection. This can happen if
the battery has recently been
replaced or if the battery has run
down. The diagnostic system
is designed to evaluate critical
emission control systems
during normal driving. This can
take several days of routine
driving. If this has been done
and the vehicle still does not
pass the inspection for lack of
OBD II system readiness,
your dealer/retailer can prepare
the vehicle for inspection.
Security Light
For information regarding this light
and the vehicle’s security system,
seeContent Theft-Deterrent
on page 2-13.
Fog Lamp Light
The fog lamp light comes on when
the fog lamps are in use.
The light goes out when the fog
lamps are turned off. SeeFog Lamps
on page 5-3for more information.
Highbeam On Light
This light comes on when the
high-beam headlamps are in use.
SeeHeadlamp High/Low-Beam
Changer on page 4-7for more
information.
4-20 Instruments and Controls

Daytime Running Lamps
(DRL) Indicator Light
This light turns on whenever the
Daytime Running Lamps are on.
SeeDaytime Running Lamps (DRL)
on page 5-2for more information.
Door Ajar Light
When the ignition is on, this light
stays on until all doors are closed
and completely latched.
If a door is not closed properly,
a chime sounds after the engine is
started and the vehicle is not in
P (Park).
Oil Pressure Gage
The gage shows the engine oil
pressure.
It is located in the center of the
instrument panel.
{CAUTION
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches re.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice:Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule in this manual for
changing engine oil.
Fuel Gage
The fuel gage shows about how
much fuel you have left, when the
ignition is on.
When the indicator nears empty,
the low fuel warning light will come
on and along with a chime.
There is still a little fuel left,
but you should refuel soon.
Here are four things that some
owners ask about. These are normal
and do not indicate a problem
with your fuel gage:
At the service station, the gas
pump shuts off before the gage
reads full.
It takes a little more or less fuel
to ll up than the gage indicated.
The indicator moves a little when
you turn a corner or speed up.
The gage will continue to show
the remaining fuel when the
ignition is turned off.

If you put things inside the
vehicle — like suitcases,
tools, packages, or anything
else — they will go as fast as
the vehicle goes. If you have
to stop or turn quickly, or if there
is a crash, they will keep going.
{CAUTION
Things you put inside the
vehicle can strike and injure
people in a sudden stop or
turn, or in a crash.
Put things in the trunk of
your vehicle. In a trunk,
put them as far forward as
you can. Try to spread the
weight evenly.
(Continued)
CAUTION (Continued)
Never stack heavier
things, like suitcases,
inside the vehicle so that
some of them are above
the tops of the seats.
Do not leave an unsecured
child restraint in the
vehicle.
When you carry something
inside the vehicle, secure it
whenever you can.
Do not leave a seat folded
down unless you need to.
Fuel
Use of the recommended fuel is
an important part of the proper
maintenance of this vehicle.
To help keep the engine clean and
maintain optimum vehicle
performance, we recommend the
