check engine light CHEVROLET CORVETTE 1997 5.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
Air bags inflate with great force, faster than the
blink
of an eye. If you’re too close to an inflating
air bag, it could seriously injure you. Safety belts
help keep you in position before and during
a
crash. Always wear your safety belt, even with air
bags. The driver should sit as far back as possible
while still maintaining control
of the vehicle.
An inflating
air bag can seriously injure small
children. Always secure children properly in your
vehicle.
To read how, see the part of this manual
called “Children” and the caution label on the
passenger’s safety belt.
There is an air bag
readiness light on the
instrument panel, which
shows AIR BAG.
The system checks the air bag electrical system for
malfunctions. The light tells you if there is an electrical
problem. See “Air Bag Readiness Light” in the Index
for more information.

If the vehicle’s safety belt will fasten around you, you
should use it.
But if a safety belt isn’t long enough to fasten, your
dealer will order you an extender. It’s free. When you go
in to order it, take the heaviest coat you will wear,
so the
extender will be long enough for you. The extender will
be just for you, and just for the seat in your vehicle that
you choose. Don’t let someone else use it, and use it
only for the seat it is made to fit.
To wear it, just attach it
to the regular safety belt.
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors and
anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from
doing its job, have it repaired.
Tom or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces.
If a belt is
torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced, (The air bag system
does not need regular maintenance.)

Downloaded from www.Manualslib.com manuals search engine PASS-Key@
Your vehicle is equipped
with the PASS-Key
(Personalized Automotive
Security System)
theft-deterrent system. PASS-Key is a passive
theft-deterrent system.
It works when you insert
or remove the key from
the ignition. When the
PASS-Key system senses that someone
is using the wrong key, it shuts down the vehicle’s
starter and fuel systems. For about three minutes, the
starter won’t work and fuel won’t go to the engine.
If someone tries to start your vehicle again or uses
another key during this time, the shutdown period
will start over again. This discourages someone from
randomly trying different keys with different resistor
pellets in an attempt to make a match.
The key must be clean and dry before it’s inserted in the
ignition or the engine may not start. If the SECURITY
light comes on, the key may be dirty or wet.
’ PASS-Key uses a resistor pellet in the ignition key that
matches a decoder in your vehicle. If
this happens and the starter won’t work, turn the
ignition off. Clean and dry the key, wait three minutes
and try again. If the starter still won’t work, wait three
minutes and try the other ignition key. At this time, you
may also want to check the fuses
(see “Fuses and Circuit
Breakers” in the Index). If the starter won’t work with
the other key, your vehicle needs service.
If your vehicle
does start, the first ignition key may be faulty. See your
Chevrolet dealer or a locksmith who can service the
PASS-Key.

Your preferred mirror position can be stored if you have
the memory option. See “Memory” in the Index.
Convex Outside Mirror
Your passenger’s side mirror is convex. A convex
mirror’s surface is curved
so you can see more from
the driver’s seat.
A CAUTION:
I
A convex mirror can make things (like other
vehicles) look farther away than they really are. If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder before changing lanes.
Storage Compartments
Instrument Panel Cupholder
The cupholder is located on the center console. To open
it, place your thumb
on the left side of the lid and raise

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.

Downloaded from www.Manualslib.com manuals search engine I Safety Belt Reminder Light
When the key is turned to ON or START, a chime will
come on for about eight seconds to remind people to
fasten their safety belts, unless the driver’s safety belt
is already buckled.
The safety belt light
will also come
on and
stay on until the driver’s
belt is buckled.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows a deployed air bag symbol. The
system checks the air bag’s electrical system for
malfunctions. The light tells you if there
is an electrical
problem. The system check includes the air bag sensors, the
air bag modules, the wiring and the diagnostic
module. For more information
on the air bag system,
see “Air Bag” in the Index.
This light will come on
when you start your engine,
and it will flash for a few
seconds. Then the light should
go out. This means
the system is ready.
If the air bag readiness light stays on after you
start the
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to
ON. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you if there
is a problem.

When the key is in the ON
position with the engine not
running, the voltmeter
shows the voltage output of
your battery. When the engine is running, it shows
the voltage output of the
charging system.
the rate of charge changes
J
The reading will change as
(with engine speed, for example), but if the voltmeter
reads at
9 volts or below, your instrument panel and
other systems may shut down. The DIC will read LOW
VOLTAGE when your Corvette is at
10 volts or below.
Have it checked right away. Driving with the voltmeter
reading at
10 volts or below could drain your battery
and disable your vehicle.
Brake System Warning Light
Your Corvette’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
BRAKE
This light should come on when you turn the ignition
key to START.
If it doesn’t
come on then, have it fixed
so it will be ready to warn
you
if there’s a problem.
If this warning light stays on after you start the engine,
the parking brake may be set or there may be a brake
problem. Refer to “Parking Brake” in the Index to see
if it is set.
If the parking brake is not set, have your
brake system inspected right away.

Downloaded from www.Manualslib.com manuals search engine Malfunction Indicator Lamp (Check Engine Light)
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.
