2002 CHEVROLET CORVETTE Owners Manual

2-79 Speedometer and Odometer
Your speedometer lets you see your speed in either
miles per hour (mph) or kilometers per hour (km/h).
There is only one scale for mph and km/h. When you
press the E/M (English/metric) button on the Driver
Information Center (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.
To read the odometer with the ignition off, turn on
the parking lamps.
You may wonder what happens if your vehicle needs a
new odometer installed. The mileage total of the new
odometer will be set to the original miles (kilometers)
of the old odometer. See your dealer if a new odometer
must be replaced in your vehicle.
Tachometer
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
Fuel will shut off at about 6200 rpm (6500 rpm for Z06).
If you continue to drive your vehicle at the fuel shut off
rpm, you could damage your engine. Be sure to operate
your vehicle 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 may also have a driver information center
that works along with the warning lights and gages.
See ªDriver Information Centerº in the Index.
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.

2-81 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 modules, the wiring and the diagnostic module.
For more information on the air bag system,
see ªAir Bagº in the Index.
This light will come on
when you start your vehicle,
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
vehicle or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
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.

2-82
Air Bag Off Light
When you turn the passenger's air bag off, this light will
come on and stay on to remind you that the air bag
has been turned off. This light will go off when you
turn the air bag back on again. See ªAir Bag Off
Switchº in the Index for more on this, including
important safety information.CAUTION:
If the passenger's air bag is turned off for a
person who isn't in a risk group identified by the
national government, that person won't have the
extra protection of an air bag. In a crash, the air
bag wouldn't be able to inflate and help protect
the person sitting there.
Don't turn off the passenger's air bag unless the
person sitting there is in a risk group identified
by the national government. See ªAir Bag Off
Switchº in the Index for more on this, including
important safety information.

2-83
CAUTION:
If the air bag readiness light ever comes on when
you have turned off the air bag, it means that
something may be wrong with the air bag system.
The passenger's air bag could inflate even though
the switch is off. If this ever happens, don't let
anyone whom the national government has
identified as a member of a passenger air bag
risk group sit in the passenger's position
(for example, don't secure a rear
-facing child
restraint in your vehicle) until you have your
vehicle serviced.
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.

2-84
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.

2-85 Anti-Lock Brake System Warning Light
With the anti-lock brake
system, the light will
come on when your
engine is started 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.

2-86
Active Handling System Light
The Active Handling System light will come on briefly
as you start the engine. If the light does not come on
then, have it fixed so it will be ready to warn you if
there is a problem. The light will also come on while the
system warms up and the ACT HNDLING WARMING
UP message will be displayed in the Driver Information
Center (DIC).
If the light stays on or
comes on while you are
driving, a chime sounds
and a SERVICE ACTIVE
HNDLG message appears
on the DIC, there is a
problem with your Active
Handling System and your
vehicle needs service.The driver can acknowledge this message by pressing
the RESET button. When the SERVICE ACTIVE
HNDLG message is displayed, the Active Handling
System will not assist you in controlling the vehicle.
You should have the system serviced as soon as
possible. Adjust your driving accordingly.
When the system is working, you will see the ACTIVE
HANDLING message displayed in the DIC. You may
also feel or hear the system working. This is normal.
If the driver turns off the Active Handling System by
pressing the button on the console, the Active Handling
System light will come on, a chime will sound, and the
TRAC/ACT HNDLG OFF message will be displayed in
the DIC. The Traction Control System will also be
turned off. See ªDriver Information Center Messagesº
in the Index for more information.
If the Active Handling System and the Traction Control
System are off, pressing the console button momentarily
will turn both systems on. The DIC will display the
TRAC/ACT HNDLG ON message, the instrument
cluster light will be off, and a chime will sound.
See ªDriver Information Center Messagesº in the Index
for more information.
