2004 PONTIAC GRAND PRIX ignition

Brake System Warning Light
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on brie¯y when you turn the
ignition key to RUN. If it doesn't come on then, have it
®xed so it will be ready to warn you if there's a problem.
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 doesn't
release fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.The PARKING BRAKE ON message will also appear in
the Driver Information Center (DIC) when the parking
brake is set.
The brake warning light may also come on when the
brake ¯uid is low. If this occurs, the LOW BRAKE FLUID
message will also appear in the Driver Information
Center (DIC).
If the brake warning light comes on 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. See
Towing Your
Vehicle on page 4-33.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you've pulled off the road and stopped
carefully, have the vehicle towed for service. United States

Anti-Lock Brake System Warning
Light
If your vehicle has the
Anti-lock Brake System
(ABS), this light will come
on when your engine is
started and may stay on
for several seconds.
That's normal.
If the ABS warning light comes on and stays on, there
may be a problem with the anti-lock portion of the brake
system. If the brake system warning light is not on,
you still have brakes, but you don't have anti-lock
brakes. See
Brake System Warning Light on page 3-36.If the light stays on, turn the ignition to OFF. If the light
comes on when you're driving, stop as soon as
possible and turn the ignition off. Then start the engine
again to reset the system. If the light still stays on,
or comes on again while you're driving, your vehicle
needs service. If the regular brake system warning light
isn't on, you still have brakes, but you don't have
anti-lock brakes. If the brake system warning light is
also on, you don't have anti-lock brakes and there's a
problem with your regular brakes. See
Brake System
Warning Light on page 3-36.
The anti-lock brake system warning light will come on
brie¯y when you turn the ignition key to RUN. This
is normal. If the light doesn't come then, have it ®xed
so it will be ready to warn you if there is a problem.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. The Check Engine light comes on
to indicate that there is a problem and service is
required. Malfunctions often will be indicated by the
system before any problem is apparent. This may
prevent more serious damage to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.
Notice:If you keep driving your vehicle with this
light on, after a while, your emission controls
may not work as well, your fuel economy may not
be as good and your engine may not run as
smoothly. This could lead to costly repairs that
may not be covered by your warranty.
Notice:Modi®cations made to the engine,
transaxle, 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 may cause this light to come on.
Modi®cations to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test.
3-40

This light should come on, as a check to show you it
is working, when the ignition is on and the engine is not
running. If the light doesn't come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
·Light FlashingÐ A mis®re condition has been
detected. A mis®re increases vehicle emissions
and may damage the emission control system
on your vehicle. Diagnosis and service may
be required.
·Light On SteadyÐ An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
If the Light is Flashing
The following may prevent more serious damage to
your vehicle:
·Reducing vehicle speed.
·Avoiding hard accelerations.
·Avoiding 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 stops ¯ashing and remains on steady,
see ªIf the Light Is On Steadyº following.
If the light continues to ¯ash, when it is safe to do so,
stop the vehicle.Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart
the engine. If the light remains on steady, see ªIf the
Light Is On Steadyº following. If the light is still ¯ashing,
follow the previous steps, and see your dealer for
service as soon as possible.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. See
Filling Your Tank on page 5-7.
The diagnostic system can determine if the fuel cap has
been left off or improperly installed. A loose or missing
fuel cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
3-41

Oil Pressure Light
If you have a problem with
your oil pressure, this light
may stay on after you
start the engine, or it may
come on while you are
driving.
This indicates that oil is not going through your engine
quickly enough to keep it lubricated. The engine
could be low on oil or could have some other oil
problem. Have it ®xed right away.
The oil light could also come on in two other situations:
·When the ignition is on but the engine is not running,
the light will come on as a test to show you it's
working. The light will go out when you turn the
ignition to RUN. If it doesn't come on with the ignition
on, you may have a problem with the fuse or bulb.
See
Fuses and Circuit Breakers on page 5-99.
·If you make a hard stop, the light may come on for
a moment. This is normal.
{CAUTION:
Don't 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:Damage to your engine from neglected
oil problems can be costly and is not covered
by your warranty.

Fog Lamp Light
This light will come on
when the fog lamps
are in use.
The light will go out when the fog lamps are turned off.
See ªFog Lampsº under
Exterior Lamps on page 3-12for more information.
High-Beam On Light
This light comes on
whenever the high-beam
headlamps are on.
See ªHeadlamp High/Low-Beam Changerº under
Exterior Lamps on page 3-12for additional information.
Fuel Gage
The fuel gage tells you
about how much fuel
you have left when
the ignition is on.
When the indicator nears empty, you still have a little
fuel left, but you should get more soon.
Here are four things owners usually ask about the fuel
gage. All these situations are normal and do not
indicate a problem with the fuel gage:
·At the gas station the pump shuts off before the
gage reads full.
·It takes more or less fuel to ®ll up than the gage
indicates. For example, the gage reads half full, but it
took more or less than half the tank's capacity to ®ll it.
·The gage pointer may move while cornering, braking
or speeding up.
·The gage may not indicate full when the ignition is
turned off.

Driver Information Center (DIC)
The Driver Information Center (DIC) gives you important
safety and maintenance facts. When you turn the ignition
on, all of the DIC lights illuminate for a few seconds and
the phrase WIDETRACK GP will appear. After this, the
DIC will begin working.
DIC Controls and Displays
Base Level DIC
The Driver Information Center (DIC) control buttons
and the message display screen are located above
the radio. The DIC gives you important safety and
maintenance facts concerning the vehicle. The status
of many of the vehicle's systems along with driver

Press the trip odometer button again to access TRIP A.
Press the trip odometer button again to access TRIP B.
To reset the trip odometer(s) back to zero miles or
kilometers, access the trip you want to reset and press
the set/reset button.
The trip odometer has a feature called the retro-active
reset. This can be used to set the trip odometer to the
number of miles or kilometers driven since the ignition
was last turned on. This can be used if you forget to reset
your trip odometer at the beginning of the trip.
To use the retro-active reset feature, press and hold the
set/reset button for at least three seconds. The trip
odometer will display the number of miles or kilometers
driven since the ignition was last turned on and you
began driving. Once you begin driving, the trip odometer
will accumulate mileage. For example, if you have
driven 5.0 miles (8.0 km) since you started the vehicle,
and then activate the reto-active reset feature, the
display will show 5.0 miles (8.0 km) since you started
your vehicle. As you drive, the display will then increase
to 5.1 miles (8.2 km), 5.2 miles (8.4 km), etc.
If the retro-active reset feature is activated after the
vehicle is started, but before it begins moving, the
display will show the number of miles or kilometers
that were driven during the last ignition cycle.
