Warning Lights, Gauges
and Indicators
This section describes the warning lights
and gauges that may be on your vehicle.
The pictures will help you locate them.
Warning lights and gauges 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 gauges could
also save you or others from injury.
Warning lights go 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 turn the
ignition key just to let you know they’re
working. If you are familiar with this
section, you should not be alarmed when
this happens.
Gauges can indicate when there may be
or is a problem with one of your vehicle’s
functions. Often gauges and warning
lights work together to
let you know
when there’s a problem with your vehicle.
... 82
When one of the warning lights comes on
and stays on when you are driving, or
when one of the gauges shows there may
be a problem, check the section that tells
you what to do about
it. Please follow the
manual’s advice. Waiting to
do repairs
can be costly
- and even dangerous. So
please get to know your warning lights
and gauges. They’re a big help.
Your vehicle also has a driver information
center that works along with the warning
lights and gauges. See “Driver Information Center’’
in the Index.
System Problems
If “SYS” flashes on the display near your
fuel gauge, there may be a problem with
your Corvette’s electrical system. If the
“SECURITY” light flashes at the same
time, there is a problem with your theft
deterrent system. Have your vehicle
checked by your dealer
if “SYS’ keeps
appearing.
Gauge Markings
The analog gauges provide a quick visual
reference to the actual measurement of
these gauges. However, you must keep in mind that the gauges aren’t linear. This means that the middle mark is not
a
temperature halfway between the top and
bottom temperatures on the gauge. For
example, the middle mark on the coolant
gauge represents 210°F,
not 180°F as you
might expect.

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 “Universal Theft
Deterrent” and “PASS-Key” in the Index.
