2009 Pontiac G8 Owner ManualM

SeeAdding Equipment to Your
Airbag-Equipped Vehicle on
page 1-32for 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 will be
lit. 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 the vehicle
should be serviced. There are parts
of the airbag system in several
places around the vehicle. Your
dealer/retailer and the service
manual have information about
servicing the 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.
Seats and Restraints 1-31

When the ignition is on, the brake
system warning light will also
come on when you set your parking
brake. The light will stay on if
your parking brake does not release
fully. If it stays on after your
parking brake is fully released, it
means you have a brake problem.
If the light comes on and Brake
message comes on the Driver
Information Center (DIC), while you
are driving, pull off the road and
stop carefully. You may notice that
the pedal is harder to push or
the pedal may go closer to the oor.
It may take longer to stop. If the
light is still on, have the vehicle
towed for service. SeeAntilock
Brake System (ABS) Warning Light
on page 4-16andTowing Your
Vehicle on page 9-88.{CAUTION
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after the
vehicle has been pulled off the
road and carefully stopped, have
the vehicle towed for service.
The Brake message will remain until
3(Trip/Fuel) or8(Enter) are
pressed, but the brake light will
remain until the problem is xed.
SeeDIC Warnings and Messages
on page 4-26for more information.
Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light will come on
briey, as a check, when you start
your vehicle.
If it does not, have your vehicle
serviced so that the light works
properly when it needs to.
If the light and a message in the DIC
stays on longer than a few seconds
after you start your engine, or comes
on and stays on while you are
driving, try resetting the system.
To reset the system:
1. If you are driving, pull over when
it is safe to do so.
2. Place the vehicle in P (Park).
3. Turn off the ignition.
4. Then restart the engine.
4-16 Instruments and Controls

If the light remains on after resetting
the system or comes on again
while driving, your vehicle needs
service. If the ABS light is on,
but the regular brake system
warning light is not on, the antilock
brakes are not working properly,
but the regular brakes are still
functioning. Have your vehicle
serviced right away. If both brake
lights are on, you do not have
antilock brakes, and there’s a
problem with your regular brakes as
well. Have your vehicle towed for
service. SeeTowing Your Vehicle
on page 9-88.
The ABS Fault message will remain
until
3(Trip/Fuel) or8(Enter)
are pressed, but the warning
light will remain until the problem is
xed. SeeDIC Warnings and
Messages on page 4-26for more
information.
Engine Coolant
Temperature Gage
This gage shows the engine coolant
temperature. If the gage pointer
moves into the red area, the engine
is too hot. It means that the engine
has overheated. Pull off the road,
stop the vehicle, and turn off the
engine as soon as possible. See
Engine Overheating on page 9-20.
Tire Pressure Light
TPMS Light
This light comes on briey when the
engine is started and provides
information about tire pressures and
the Tire Pressure Monitoring System.When the Light is On Steady
This light will also come on when
one or more of your tires are
signicantly underinated. A CHECK
TIRE PRESSURE DIC message
will accompany the light.
SeeDIC Warnings and Messages
on page 4-26for more information.
Stop and check your tires as soon
as it is safe to do so. If underinated,
inate to the proper pressure.
SeeTires on page 9-42for more
information.
When the Light Flashes First and
Then is On Steady
This indicates that there may be a
problem with the Tire Pressure
Monitor System.
The light ashes for about a minute
and stays on on steady for the
remainder of the ignition cycle.
This sequence will repeat with every
ignition cycle. SeeTire Pressure
Monitor System on page 9-52
andTire Pressure Monitor Operation
on page 9-54for more information.
Instruments and Controls 4-17

This light comes on during a
malfunction in one of two ways:
Light Flashing:A misre condition
has been detected. A misre
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
The following can prevent more
serious damage to the vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If towing a trailer, reduce the
amount of cargo being hauled
as soon as it is possible.
If the light continues to ash,
when it is safe to do so, stop the
vehicle. Find a safe place to
park the vehicle. Turn the key off,
wait at least 10 seconds, and restart
the engine. If the light is still ashing,
follow the previous steps and see
your dealer/retailer for service as
soon as possible.Light On Steady:An emission
control system malfunction has been
detected on the vehicle. Diagnosis
and service might be required.
An emission system malfunction
might be corrected by doing
the following:
Make sure the fuel cap is fully
installed. SeeFilling the Tank on
page 8-37. The diagnostic system
can determine if the fuel cap
has been left off or improperly
installed. A loose or missing fuel
cap allows fuel to evaporate into
the atmosphere. A few driving
trips with the cap properly
installed should turn the light off.
If the vehicle has been driven
through a deep puddle of water,
the vehicle’s electrical system
might be wet. The condition is
usually corrected when the
electrical system dries out.
A few driving trips should turn
the light off.
Make sure to fuel the vehicle with
quality fuel. Poor fuel quality
causes the engine not to run as
efficiently as designed and may
cause: stalling after start-up,
stalling when the vehicle is
changed into gear, misring,
hesitation on acceleration, or
stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these conditions
occurs, change the fuel brand
used. It will require at least one
full tank of the proper fuel to turn
the light off.
SeeGasoline Octane on
page 8-35.
If none of the above have made the
light turn off, your dealer/retailer can
check the vehicle. The dealer/retailer
has the proper test equipment and
diagnostic tools to x any mechanical
or electrical problems that might
have developed.

New Vehicle Break-In
Notice:Your vehicle does not
need an elaborate break-in. But it
will perform better in the long
run if you follow these guidelines:
Do not drive at any one
constant speed, fast or slow,
for the rst 500 miles (805 km).
Do not make full-throttle
starts. Avoid downshifting to
brake or slow the vehicle.
During the rst 600 miles
(1 000 km), avoid using more
than moderate acceleration
in lower gears and avoid
vehicle speeds above 68 mph
(110 km/h).
Between the rst 600 miles
(1 000 km) and 3,000 miles
(5 000 km), heavy acceleration
in lower gears can be used.
Vehicle speeds above 68 mph
(110 km/h) should be limited to
ve minutes per use.
Avoid making hard stops for the
rst 200 miles (322 km) or so.
During this time the new brake
linings are not yet broken in.
Hard stops with new linings can
mean premature wear and
earlier replacement. Follow this
breaking-in guideline every
time you get new brake linings.
Do not tow a trailer during
break-in. SeeTowing a Trailer
on page 9-89for the trailer
towing capabilities of your
vehicle and more information.
Following break-in, engine speed
and load can be gradually
increased.
Ignition Positions
The ignition switch has four different
positions.
Notice:Using a tool to force the
key to turn in the ignition could
cause damage to the switch or
break the key. Use the correct key,
make sure it is all the way in, and
turn it only with your hand. If the
key cannot be turned by hand,
see your dealer/retailer.
To shift out of P (Park), turn the
ignition to ON/RUN and apply
the brake pedal.
