2000 CHEVROLET CORVETTE ignition

2-75
CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
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.
Voltmeter
When the key is in ON 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 cluster
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.
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 still be set or there could be a
brake problem. Refer to ªParking Brakeº in the
Index to see if it is set. If the parking brake is not set,
have your brake system inspected right away.If the light comes on while you are driving and you have
a LOW BRAKE FLUID message showing on the DIC,
pull off the road and stop carefully. You may notice that
the pedal is harder to push. Or, the pedal may go closer
to the floor. It may take longer to stop. If the light is still
on, have the vehicle towed for service. (See ªTowing
Your Vehicleº in the Index.)
CAUTION:
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.

2-77 Anti-Lock Brake System Warning Light
With the anti-lock brake
system, the light will come
on when you start your
engine and may stay on
for several seconds.
That's normal.
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 ªBrake System
Warning Lightº earlier in this section. Also see
ªSERVICE ABSº under ªDriver Information
Center (DIC) Messagesº in the Index.
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.
Traction Control System (TCS) Light
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.
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.

2-79 Engine Coolant Temperature Gage
United States Canada
This gage shows the engine coolant temperature. If the
gage pointer moves into the shaded area, your engine is
too hot.
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.
(The larger tic marks are in increments of 30
below
220
F (104
C) and in increments of 10

above 220
F (104
C).)
See ªEngine Overheatingº in the Index for
more information.
Malfunction Indicator Lamp
(Check Engine Light)
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (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.

2-80
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.
NOTICE:
Modifications made to the engine, transmission,
exhaust 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 the CHECK ENGINE light to
come on. Modifications 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 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.

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.
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.

2-83
CAUTION:
Don't keep driving if the oil pressure is low.
If you do, your engine can become so hot that it
catches fire. 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.
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 ªTheft
-Deterrent Systemº and ªPASS-Key Systemº
in the Index.
Check Gages Warning Light
This light will come on
briefly 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

2-84
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 ªE,º
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 four 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 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
fit it.

The gage pointer may move while cornering, braking
or speeding up.

The gage may not indicate EMPTY (E) when the
ignition is turned off.
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: The fuel economy calculated for your current
driving conditions.

RANGE: The distance you can drive before refueling.

BLANK: The fuel gage is displayed alone.

2-88
If the ignition is on and you can't see the HUD image,
check to see if:

Something is covering the HUD unit.

The HUD dimmer control is adjusted properly.

The HUD image is adjusted to the proper height.

Ambient light (in the direction your vehicle is
facing) is low.

A fuse is blown. See ªFuses and Circuit Breakersº
in the Index.
Keep in mind that your windshield is part of the HUD
system. If you ever have to have your windshield
replaced, be sure to get one that is designed for HUD or
your HUD image may look blurred and out of focus.
Driver Information Center (DIC)
The Driver Information Center (DIC) will display
information about how your vehicle is functioning,
as well as warning messages if a system problem is
detected. The DIC display area is located in the
instrument panel cluster below the speedometer
and tachometer, directly above the steering column.The following buttons are located on the DIC control
panel which is located to the right of the instrument
panel cluster.
1 FUEL: Press this button to display fuel information
such as fuel economy and range.
2 GAGES: Use this button to display gage information
like oil pressure and temperature, coolant temperature,
transmission fluid temperature, battery voltage and
front/rear tire pressures.
