1997 CHEVROLET CORVETTE fuel

Downloaded from www.Manualslib.com manuals search engine Speedometer
Your speedometer lets you see your speed in either miles
per hour (mph) or kilometers per hour
(km/h).
You may note that there are not two separate scales
for mph and
km/h. When you press the EM
(EnglisMetric) button on the DIC, the cluster
will calculate the proper speed and move the needle
to the correct position. Either the
MPH or the km/h
telltale will illuminate, depending on which
measurement you choose.
Tachometer
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
Fuel will shut off at about
6200 rpm.
If you continue to drive your Corvette at the fuel shut
off rpm, you could damage your engine. Be sure to
operate your Corvette below the fuel shut
off rpm or
reduce your rpm quickly when the fuel shuts off.
Warning Lights, Gages.and Messages
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them. Warning
lights and gages can signal that something
is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions.
As
you will see in the details on the next few pages,
some warning lights come on briefly when you start
the engine just to let you know they’re working. If
you are familiar with this section, you should not be
alarmed when this happens.
Gages can indicate when there may be or is a problem
with one
of your vehicle’s functions. Often gages and
warning lights work together to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays
on when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Please follow this manual’s
advice. Waiting to
do repairs can be costly -- and even
dangerous.
So please get to know your warning lights
and gages. They’re a big help.
Your vehicle also has a Driver Information Center that
works along with the warning lights and gages.
See
“Driver Information Center” in the Index.

CHECK
Your Corvette is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD I1 (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. (In Canada, OBD
I1 is replaced by
Enhanced Diagnostics.) 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.
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:
0
0 Light Flashing -- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service
is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.

Downloaded from www.Manualslib.com manuals search engine If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
0 Avoiding hard accelerations.
0 Avoiding steep uphill grades.
If the light stops flashing and remains on steady, see “If
the Light Is On Steady” following.
If the light continues to flash, 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 flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
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
“Fuel” in the Index). 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, misfiring, 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,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.

At the gas station, the fuel pump shuts off before the
gage reads FULL
(F).
It takes more (or less) fuel to fill 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
fill it.
The gage moves a little when you turn, stop or
