2003 CHEVROLET CORVETTE fuel pump

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).

Gasoline Speci®cations
It is recommended that gasoline meet speci®cations
which were developed by the American Automobile
Manufacturers Association and endorsed by the
Canadian Vehicle Manufacturers Association for better
vehicle performance and engine protection. Gasoline
meeting these speci®cations could provide improved
driveability and emission control system performance
compared to other gasoline.
In Canada, look for the
ªAuto Makers' Choiceº
label on the pump.
California Fuel
If your vehicle is certi®ed to meet California Emission
Standards (see the underhood emission control label), it
is designed to operate on fuels that meet California
speci®cations. If this fuel is not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
speci®cations, but emission control system performance
may be affected. The malfunction indicator lamp may
turn on (see
Malfunction Indicator Lamp on page 3-38)
and your vehicle may fail a smog-check test. If this
occurs, return to your authorized GM dealer for
diagnosis. If it is determined that the condition is caused
by the type of fuel used, repairs may not be covered
by your warranty.

{CAUTION:
If you get fuel on yourself and then something
ignites it, you could be badly burned. Fuel can
spray out on you if you open the fuel cap too
quickly. This spray can happen if your tank is
nearly full, and is more likely in hot weather.
Open the fuel cap slowly and wait for any
ªhissº noise to stop. Then unscrew the cap all
the way.
Be careful not to spill fuel. Clean fuel from painted
surfaces as soon as possible. See
Cleaning the Outside
of Your Vehicle on page 5-78.
When you put the fuel cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make
sure you fully install the cap. The diagnostic system can
determine if the fuel cap has been left off or improperly
installed.
This would allow fuel to evaporate into the atmosphere.
See
Malfunction Indicator Lamp on page 3-38.
Notice:If you need a new fuel cap, be sure to get
the right type. Your dealer can get one for you.
If you get the wrong type, it may not ®t properly.This may cause your malfunction indicator lamp
to light and may damage your fuel tank and
emissions system. See ªMalfunction Indicator
Lampº in the Index.
Filling a Portable Fuel Container
{CAUTION:
Never ®ll a portable fuel container while it is in
your vehicle. Static electricity discharge from
the container can ignite the gasoline vapor.
You can be badly burned and your vehicle
damaged if this occurs. To help avoid injury to
you and others:
·Dispense gasoline only into approved
containers.
·Do not ®ll a container while it is inside a
vehicle, in a vehicle's trunk, pickup bed or
on any surface other than the ground.
·Bring the ®ll nozzle in contact with the
inside of the ®ll opening before operating
the nozzle. Contact should be maintained
until the ®lling is complete.
·Don't smoke while pumping gasoline.
