2008 PONTIAC G8 light

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 PARK (P).
3. Turn off the ignition.
4. Then restart the engine.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 9-84.
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 4-27for 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 9-16.

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 Solid
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 4-27for more information.Stop and check your tires as soon as
it is safe to do so. If underinated,
inate to the proper pressure. See
Tires on page 9-39for more
information.
When the Light Flashes First and
Then is Solid
This indicates that there may be a
problem with the Tire Pressure
Monitor System.
The light ashes for about a minute
and stays on solid for the
remainder of the ignition cycle. This
sequence will repeat with every
ignition cycle. SeeTire Pressure
Monitor System on page 9-49
andTire Pressure Monitor Operation
on page 9-51for 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 makes sure that
emissions are at acceptable
levels for the life of the vehicle,
helping to produce a cleaner
environment.
This light comes on briey, as a
check to show it is working,
when the ignition is turned to
ON/RUN. If the light does not come
on, see your dealer/retailer.
If the light stays on it indicates that
there is an OBD II problem and
service is required.

Malfunctions often are indicated by
the system before any problem
is apparent. Heeding the light can
prevent more serious damage
to your vehicle. This system assists
your service technician in correctly
diagnosing any malfunction.
Notice:If you keep driving your
vehicle with this light on, after
a while, the emission controls
might not work as well, your
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 your
warranty.
Notice:Modications made to
the engine, transmission, exhaust,
intake, or fuel system of your
vehicle or the replacement of the
original tires with other than those
of the same Tire Performance
Criteria (TPC) can affect your
vehicle’s emission controls and
can cause this light to come on.
Modications to these systemscould lead to costly repairs not
covered by your warranty. This
could also result in a failure to
pass a required Emission
Inspection/Maintenance test.
SeeAccessories and
Modifications on page 9-3.
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 your vehicle. Diagnosis
and service might be required.
The following can prevent more
serious damage to your vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If you are 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 your vehicle. Diagnosis
and service might be required.
You might be able to correct the
emission system malfunction
by considering the following:
Make sure the fuel cap is fully
installed. SeeFilling the Tank
on page 8-35. 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.
Instruments and Controls 4-19

If you just drove through a deep
puddle of water, your 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.
If you recently changed brands of
fuel, be sure to fuel your vehicle
with quality fuel. SeeGasoline
Octane on page 8-33. Poor
fuel quality causes the engine
not to run as efficiently as
designed. You might notice this
as stalling after start-up,
stalling when you put the vehicle
into gear, misring, hesitation
on acceleration, or stumbling on
acceleration — these conditions
might go away once the
engine is warmed up.
If you experience one or more of
these conditions, change the
fuel brand you use. It will require
at least one full tank of the
proper fuel to turn the light off.If none of the above have made
the light turn off, your dealer/retailer
can check the vehicle. Your
dealer/retailer has the proper test
equipment and diagnostic tools to
x any mechanical or electrical
problems that might have
developed.
Emissions Inspection and
Maintenance Programs
Some state/provincial and local
governments have or might begin
programs to inspect the emission
control equipment on your vehicle.
Failure to pass this inspection
could prevent getting a vehicle
registration.Here are some things to know to
help your vehicle pass an
inspection:
Your vehicle will not pass this
inspection if the check engine
light is on or not working properly.
Your vehicle will not pass
this inspection if the OBD
(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 for
inspection. This can happen if
you have recently replaced
the battery 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 you have done this and
your vehicle still does not pass
the inspection for lack of
OBD system readiness, your
dealer/retailer can prepare
the vehicle for inspection.

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. If you do, your
engine can become so hot that
it catches re. You or others
could be burned. Check your
oil as soon as possible and
have your vehicle serviced.
Notice:Lack of proper engine oil
maintenance may 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.
