CHEVROLET CORVETTE 2003 5.G Owners Manual

Notice:Modi®cations 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 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.
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 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 also 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.
3-39

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.

Engine Oil Pressure Gage
The engine oil pressure gage shows the engine oil
pressure in psi (pounds per square inch) or kPa
(kilopascals) when the engine is running.
Oil pressure should be 20 to 80 psi (140 to 550 kPa). In
certain situations such as long, extended idles on hot
days, it could read as low as 6 psi (40 kPa) and still be
considered normal. It may vary with engine speed,
outside temperature and oil viscosity, but readings
above the shaded area show the normal operating
range. Readings in the shaded area tell you that
the engine is low on oil, or that you might have some
other oil problem. See
Engine Oil on page 5-13.The engine oil pressure can also be displayed using the
GAGES button on the Driver Information Center (DIC).
See
Driver Information Center (DIC) on page 3-44.
{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. United States

Security Light
This light comes on to
remind you to arm your
theft-deterrent system. If it
comes on and stays on
when your ignition is
on, there may be a
problem with your
theft-deterrent system.
See
Theft-Deterrent System on page 2-16andPASS-Keyžon page 2-17.
Check Gages Warning Light
This light will come on
brie¯y when you are
starting the engine. If the
light comes on and
stays on while you are
driving, check your gages
to see if they are in the
warning areas.This light can come on for the following reasons:
·Low Oil Pressure
·High Coolant Temperature
·High or Low Battery Voltage
·Low Fuel Level
Fuel Gage
Your fuel gage tells you
about how much fuel you
have left when the
ignition is on.
When the needle approaches the red zone, RESERVE
FUEL will appear on the Driver Information Center (DIC)
display. When the needle approaches the E, LOW
FUEL will appear on the display. At this time, you still
have a little fuel left, but you should get more soon.

Press RESET to acknowledge a DIC message(s).
Pressing RESET will also turn off a DIC message but
the LOW FUEL message will come on again in
10 minutes if you have not added fuel to the vehicle.
Here are ®ve things that some owners ask about.
All these things are normal and do not indicate that
anything is wrong with the fuel gage.
·At the gas station, the gas pump shuts off before
the gage reads F (full).
·It takes more (or less) fuel to ®ll up than the gage
reads. For example, the gage reads half full, but it
took more (or less) than half of the tank's
capacity to ®t it.
·The gage pointer may move while cornering,
braking or speeding up.
·The gage may not indicate E (empty) when the
ignition is turned off.
·The gage reading may change slightly within the
®rst several minutes after starting the vehicle.You can use the Driver Information Center (DIC) to
display more detailed fuel information. Each time you
press FUEL, one of the following will appear in the
Driver Information Center (DIC).
·AVERAGE:The fuel economy calculated for the
current tank of fuel, or since you last reset the
display.
·INST (Instant):The fuel economy calculated for
your current driving conditions.
·RANGE:The distance you can drive before
refueling.
You should reset the fuel information display every time
you refuel. To reset the display, press FUEL until
AVERAGE appears. Then, press RESET on the Driver
Information Center (DIC).
