direction
of the turn or lane change.
To signal a lane change, just raise or lower the lever
until the green arrow starts to flash. Hold it there until
you complete your lane change. The lever will return by
itself when you release it.
As you signal a turn or a lane change, if the arrows don’t
flash but just stay on, a signal bulb may be’burned out
and other drivers won’t see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the green arrows don’t go on at all when you
signal a turn, check the fuse (see “Fuses” in the Index)
and for burned-out bulbs.

Downloaded from www.Manualslib.com manuals search engine Your Corvette’s odometer is tamper-resistant. It will
read
OD0 ERR if someone has tampered with it.
If a new odometer is installed, it will 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 OD0 on the
Trip Monitor.
To reset it, press and hold RESET TRIP
for two seconds.
Tachometer
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
Fuel will shut off at
7200 rpm for the LT5 (Code J)
engine and at 5850 rpm for the LT1, (Code P) engine.
If you continue to drive your Corvette at the fuel shut
off rpm, you could damage your engine. Be sure to
operate your Corvette below the fuel shut
off rpm or
reduce your rpm quickly when the fuel shuts off.
Warning Lights, Gauges and
Indicators
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 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.
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.
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 this 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.

Downloaded from www.Manualslib.com manuals search engine Your vehicle also has a driver information center that
works along with the warning lights and gauges. See
“Driver Information Center” in the Index.
Safety Belt Reminder Light
When the key is turned to
RUN 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.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. 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 sensors and the wiring and the
diagnostic module. For more information on the air bag
system, see “Air Bag” in the Index.
AIR
BAG
You will see this light flash
for a few seconds when you
turn your ignition to RUN
or START. Then the light
should go out. This means
the system is ready.
If the air bag readiness light doesn’t come on when
you
start your vehicle, or stays on, or comes on when you
are driving, your air bag system may not work properly.
Have your vehicle serviced right away.

.
This red light will come on
when you turn on the
ignition, but the engine is
not running, as a check to
show you it is working. It
should go out when the
engine starts.
If it stays on or comes on while you
are driving, you
may have a problem with the electrical charging system.
It could indicate that you have a loose
or broken drive
belt
or another electrical problem. Have it checked right
away. Driving while this light is on could drain your
battery.
If you must drive a short distance with the light on, be
certain to turn
off all your accessories, such as the radio
and
air conditioner.
Brake System Warning Light

SERVICE
With the anti-lock brake
system, this light will come
on when you start your
engine and may stay on for
several 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 a problem.
Anti-Lock Brake System Active Light
ABS
ACTIVE
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
the
ABS ACTIVE light will
come on. Slippery road
conditions may exist
if this
light comes on,
so adjust
your driving accordingly.
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. The
light will stay on for a few seconds after the system
stops adjusting brake pressure.
The ABS ACTIVE light also comes on briefly, as a bulb
check, when the engine is started. If the light doesn’t
come on then, have it fixed
so it will be there to tell you
when the system is active.

Downloaded from www.Manualslib.com manuals search engine 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 LOWLFLAT 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. 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
1995 Corvette Service Manual for correct tire mounting
and dismounting procedures.
The LOWELAT 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.
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.

SERVICE
LTPWS
The amber SERVICE
LTPWS light comes on
whenever a LTPWS part is
not working properly. It
may also come on when
you’re going less than
25 mph (40 km/h) or in
stop-and-go traffic.
The light will
go out when the electronic receiver gets a
signal from each sensor.
Check the system by turning the ignition on. The light
should come on and then
go out. See your dealer if the
light stays on or doesn’t come on.
Here
are two situations that cause the SERVICE LTPWS
light to come on and stay on. Both of these situations are
normal and do qot indicate that anything is wrong with
your Corvette.
You turn the ignition on three times in a row for half
an hour without moving your Corvette. The light will
then come on every time you turn the ignition on
until you move your Corvette.
You run your Corvette three times for half an hour
while all four sensors
are missing. (All the sensors
would be missing, for example, if you put different
wheels on your Corvette without transferring the
sensors.)
If you would like to clear the SERVICE LTPWS light
from your driver information center permanently, see
your dealer.
If the light comes on and stays on, even when the
vehicle is driven, there may be a problem with LTPWS.
See your dealer.
Door Ajar Light
This red light comes on
when you open one of the
doors with the ignition on.
It stays on until you fully
close the door. Have your
vehicle serviced
if the light
comes on and stays on even
when the doors are fully
closed.

When the engine is 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.
Readings between the shaded areas show the normal
operating range. The reading will change as the rate
of
charge changes (with engine speed, for example), but if
the voltmeter reads in either shaded area, and it stays
there, you may have a problem with the charging system,
Have it checked right away. Driving with the voltmeter
reading in a shaded area could drain your battery.

PSI
The engine oil pressure gauge shows the engine
oil pressure in psi (pounds per square inch) or
kPa (kilopascals) when the engine is running. Oil
pressure should be
20 to 80 psi (140 to 550 Ea). It
may vary with engine speed, outside temperature and oil
viscosity, but readings above the shaded area show the
normal operating range. Readings in the shaded area tell
you that the engine is low on oil, or that you might have
some other oil problem. See “Engine Oil” in the Index.
