1998 CHEVROLET CORVETTE light

Downloaded from www.Manualslib.com manuals search engine Voltmeter
I 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 reading will change as the rate of charge changes
(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 Driver Information
Center (DIC) will read LOW
VOLTAGE when your
vehicle 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 vehicle’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 not be set or there could 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.

That’s’normal.
Your brake system may not be working properly
if the brake warning light is on. Driving with the
brake warning light on can lead to an accident.
If
the light is still on after you’ve pulled off the road
and stopped carefully, have the vehicle towed
for service.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on when you’re driving, stop as soon as
possible and turn the ignition
off. Then start the engine
again to reset the system.
If the light still stays on, or
comes
on again while you’re driving, your vehicle needs
service. If the regular brake system warning light isn’t
on, you still have brakes, but you don’t have anti-lock
brakes. If the regular brake system warning light
is also
on, you don’t have anti-lock brakes and there’s a
problem with your regular brakes. See “Brake System
Warning Light” earlier in this section.
The anti-lock brake system warning light should come
on briefly 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.

Engine Coolant Temperature Gage
I
This light should come on
briefly as you start the
engine. If the light doesn’t
come on then, have it fixed
so it will be ready to warn
you if there’s a problem. This gage shows
the engine
coolant temperature. If the
gage pointer moves into the
shaded area, your engine is
too hot!
If it stays on, or comes on and the DIC shows a
SERVICE TRACTION SYSTEM message when you’re
driving, there’s a problem with your TCS system and
your vehicle needs service. When this light is on, the
system will not limit wheel spin. Adjust your driving
accordingly. If the driver
turns off the Traction Control
System by pressing the button on the console, the TCS
system light will come on and the TRACTION
SYSTEM
OFF message will show on the DIC. This means that your engine coolant has overheated.
If
you have been operating your vehicle under normal
driving conditions, you should pull
off the road, stop
your vehicle and turn
off the engine as soon as possible.

of 30 O below

CHECK
Your vehicle 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. 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 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 may be required.
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.
Light On Steady -- An emission control system

Downloaded from www.Manualslib.com manuals search engine 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 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.
