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

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.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
See
Gasoline Octane on page 5-4. 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, mis®ring,
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.

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.

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.

Setting the Compass
The compass is self-calibrating, which eliminates the
need to manually set the compass.
However, under certain circumstances, such as during a
long distance cross-country trip, it will be necessary
to compensate for compass variance and reset the zone
through the DIC.
Compass variance is the difference between earth's
magnetic north and true geographic north. If not
adjusted to account for compass variance, the compass
in your vehicle could give you false readings.
In order to do this, you will have to set or calibrate the
compass to the variance zone in which you are located.
