Instrument Cluster
Your instrument cluster and Driver
Information Center are designed to let
you know at a glance how your 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
center display in
the cluster is
controlled by the Trip Monitor.
Speedometer and Odometer
Your speedometer lets you see your
speed in either miles per hour (mph)
or kilometers per hour (kmh).
Your
odometer shows how far your vehicle has
been driven,
in either miles or kilometers.

automatically reset to the correct reading.
If an electrical or other problem makes
setting the odometer correctly impossible,
then it’s set at zero, but
a label on the
driver’s door must show the old reading
and when the new one was installed.
Trip Odometer
The trip odometer can tell you how far
your Corvette has been driven since you
last set the trip odometer to zero.
To display the trip odometer, press
“TRIP ODO” on the Trip Monitor. To
reset it, press and hold “RESET TRIP”
for two seconds.

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.

Downloaded from www.Manualslib.com manuals search engine For your convenience, the following table
gives the reading for each mark.
For numeric gauge measurements, refer to
the digital readings by pressing
“GAUGES” on the Trip Monitor.

Fuel Gauge
Your fuel gauge shows about how much
fuel is in your tank. The bars light up
when the ignition is on or, if the ignition
is
off, when you turn on your parking
lights.
When the display
is down to the last two
bars,
“RESERVE” will appear next to the
gauge.
Here are three concerns some owners
have had about the fuel gauge. All these
situations are normal and do not indicate
that anything is wrong with the fuel
gauge.
At the gas station, the fuel pump shuts
off before the gauge reads
“F.”

It takes more (or less) fuel to fill up
than the gauge reads. For example, the
gauge reads half full, but it took more
(or less) than half of the tank’s
capacity to fill it.
The gauge moves a little when you
turn, stop or speed up.
You can use the Trip Monitor to display
more detailed fuel information. Each time
you press “FUEL INFO,” one
of the
following will appear next to the fuel
gauge.
INST The fuel economy calculated
for your current driving conditions.
AVERAGE: The fuel economy
calculated for the current tank of fuel,
or since you last reset the display.

before refueling.

Brake System Warning Light
Your Corvette’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 as you start thc
vehicle. 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, there could be
a brake problem.
Have your brake system inspected right
away.
If the light comes on while you are
driving, pull
off the road and stop
carefully. You may notice that the pedal
is harder to push. Or, the pedal may go

Anti-Lock Brake System Warning
Light
With anti-lock, this light will come on
when you start your engine and may stay
on for about two seconds. That’s normal.
If the light doesn’t come on, have it fixed
so it will be ready to warn you if there is i
problem.
If the light stays on, turn the ignition 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 Corvette 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 part.

Low Tire Pressure Warning Light
(Option)
The LTPWS has a sensor on each road
wheel that transmits to a receiver
on the
instrument panel. The system operates on
a radio frequency subject to Federal
Communications Commission (FCC)
Rules.
This device complies with Part
15 of the
FCC Rules. Operation
is subject to the
following two conditions:
1. This device may not cause harmful
2. This device must accept any
interference,
and
interference received, including
interference that may cause undesired
operation.
Changes or modifications to this system
by other than an authorized service
facility could void authorization to use
this equipment.
LOWIFLAT
TIRE
..
The Low Tire Pressure Warning System
(LTPWS) monitors air pressure in each
road tire while you’re driving your
Corvette. The “LOW/FLAT TIRE” light
will come
on whenever tire pressure in
any road tire goes below
25 psi (175 kPa)
and it will stay
on until you turn off the
ignition. The light may come on if any
LTPWS parts aren’t working properly.
..

Downloaded from www.Manualslib.com manuals search engine Features and Controls
For LTPWS to work properly, you must
drive your Corvette faster than
25 mph
(40 km/h) and for more than
2 miles
(4 km). The system will not warn you
before
you begin to drive that a tire is flat.
When the “LOW/FLAT TIRE’ light
comes on, check
the tire pressure in all
four road tires as soon as you can. Adjust
the tire pressure as needed to those shown
on the Tire-Loading Information label on
the driver’s door. If the light stays on after
the tire pressure is adjusted, see your
dealer.
NOTICE:
Driving with a flat tire may damage
the tire,
the wheel or the tire pressure
sensor installed inside the tire on the
wheel rim. Using tire sealants may
also damage
the sensor.
If you have EMTs, see “Extended
Mobility Tires”
in the Index. The
LTPWS sensor is directly opposite
the valve stem on the tire. Take care when
servicing or having your tires serviced.
The sensors may not work properly if
damaged. To prevent damage to the
sensors, see the 1994 Corvette Service
Manual for correct tire mounting and
dismounting procedures.
The “LOWRLAT TIRE” light may come
on if your vehicle is close to another
vehicle that has LTPWS and has a tire
with low pressure.
LTPWS can
warn you about a low tire,
but it does not replace normal tire
maintenance. See “Tires” in the Index.
