PONTIAC GRAND PRIX 2005 Owners Manual

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 does not come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions and
may damage the emission control system on your
vehicle. Diagnosis and service may be required.
Light On Steady— 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 possibleIf the light stops ashing and remains on steady, see
“If the Light Is On Steady” 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 “If
the Light Is On Steady” 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. SeeFilling 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.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.
3-45

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-5. Poor fuel quality will
cause your engine not to run as efficiently as designed.
You may 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 may go away once the engine is warmed up.)
This will be detected by the system and cause the
light to turn on.
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 steps have made the light turn off,
your dealer can check the vehicle. Your dealer has
the proper test equipment and diagnostic tools to x any
mechanical or electrical problems that may have
developed.Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need 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 your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may 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 GM dealer can prepare the
vehicle for inspection.
3-46

Oil Pressure Light
If there is a problem with
the vehicle’s oil pressure,
this light may stay on
when the engine is started,
or it may come on while
the vehicle is being driven.
This indicates that oil is not going through the 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 indicate
it is working. The light will go out when the
ignition is turned to RUN. If it does not come on
while the ignition is in the on position, there may be
a problem with the fuse or bulb. SeeFuses and
Circuit Breakers on page 5-103.
If the brakes are applied quickly and the vehicle
makes a hard stop, the light may come on for a
moment. This is normal.
{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 your warranty. Always follow the maintenance
schedule in this manual for changing engine oil.
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.
SeeFog Lamps on page 3-16for more information.
3-47

Cruise Control Light
This light, if equipped,
comes on whenever you
set your cruise control.
The light will go out when the cruise control is turned off.
SeeCruise Control on page 3-10for more information.
Highbeam On Light
This light comes on
whenever the high-beam
headlamps are on.
See “Headlamp High/Low-Beam Changer” under
Exterior Lamps on page 3-14for additional information.
Fuel Gage
The fuel gage shows
about how much fuel
is left in the fuel tank
when the ignition is on.
When the indicator nears empty, there is still 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.
3-48

Driver Information Center (DIC)
The Driver Information Center (DIC) gives important
safety and maintenance facts. When the vehicle’s
ignition is turned on, all of the DIC lights illuminate for a
few seconds and an introductory message 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 important safety and maintenance
facts concerning the vehicle. The status of many of
the vehicle’s systems along with driver personal
programming mode menus and warning messages
about the vehicle’s systems may display on the

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
the trip odometer was not reset 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 the
vehicle began moving. Once the vehicle has begun
moving, the trip odometer will accumulate mileage. For
example, if the vehicle was driven 5.0 miles (8.0 km)
before the vehicle is started again, and then the
retro-active reset feature is activated, the display will
show 5.0 miles (8.0 km). As the vehicle begins moving,
the display will 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
