warning CHEVROLET CORVETTE 2003 5.G User Guide

Cruise Control
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. This can really help on long
trips. Cruise control does not work at speeds below
about 25 mph (40 km/h).
When using cruise control, the accelerator pedal will
return to its fully-released position and will not
move while cruise control is engaged.
The Driver Information Center (DIC) will display the
cruise set speed in a digital number. For example, the
DIC will say CRUISE SET 60 mph (97 km/h). The cruise
set speed and the speedometer indicated speed maynot always be exactly the same. When you apply the
brakes or push the clutch pedal, the cruise control
disengages. The DIC will show CRUISE DISENGAGED.
See
DIC Warnings and Messages on page 3-53.
{CAUTION:
·Cruise control can be dangerous where
you can't drive safely at a steady speed.
So, don't use your cruise control on
winding roads or in heavy traffic.
·Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
needless wheel spinning, and you could
lose control. Don't use cruise control on
slippery roads.
If your vehicle is in cruise control when the Traction
Control System begins to limit wheel spin, the cruise
control will automatically disengage. See
Traction
Control System (TCS) on page 4-9. When road
conditions allow you to safely use it again, you may turn
the cruise control back on.

Warning Lights, Gages and
Indicators
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 brie¯y 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 Ð 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
Driver Information Center (DIC) on page 3-44.

Instrument Panel Cluster
Your instrument panel cluster and Driver Information Center (DIC) are designed to let you know at a glance how the
vehicle is running. You'll know how fast you're going, about how much fuel you have left and many other things
you'll need to know to drive safely and economically. The instrument panel cluster indicator warning lights, gages and
DIC messages are explained on the following pages.

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 ®xed 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
Parking Brake on page 2-30to 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 ¯oor. It may take longer to stop. If the light
is still on, have the vehicle towed for service. See
Towing Your Vehicle on page 4-33.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system 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.

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
Brake System Warning Light on page 3-35. Also
see ªService ABSº underDIC Warnings and Messages
on page 3-53.
The anti-lock brake system warning light will come on
brie¯y when you turn the ignition key to ON. This is
normal. If the light doesn't come on then, have it ®xed

Warning Light
This light should come on
brie¯y as you start the
engine. If the light doesn't
come on then, have it
®xed 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.

Active Handling System Light
The Active Handling System light will come on brie¯y as
you start the engine. If the light does not come on
then, have it ®xed 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
DIC Warnings and Messages on
page 3-53for 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

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

display. When the needle approaches the E, LOW
FUEL will appear on the display. At this time, you still
have a little fuel left, but you should get more soon.
