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

Downloaded from www.Manualslib.com manuals search engine Low Tire Pressure Warning Light (Option)
The Low Tire Pressure Warning System (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 interference, and
(2) This device must accept any 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.
The (LTPWS) monitors air pressure in each road tire
while you’re driving your Corvette.
LOW/FLAT
TIRE
The amber 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.
2-76

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.

control systems. This amber
light should come on when
the ignition is on, but the
engine is not running, as a
check to show you it is
working.
If it does not come
on at all, have it fixed right away. If
it stays on, or it comes on while you are driving, the
computer is indicating that you have
a problem. You
should take your vehicle in for service soon.

OIL
PRESS
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.

warranty.
Engine Oil Temperature Gauge
LT1 LT5
This gauge shows your engine oil temperature. Oil
temperature may vary with the type
of driving you do
and weather conditions. If your gauge pointer moves
close to or into the shaded area and stays there, your oil
temperature is too high. Check the engine coolant
temperature and engine oil level. If your engine is too
hot, see “Engine Overheating” in the Index. Your
vehicle may need service; see your dealer.
2-81

Downloaded from www.Manualslib.com manuals search engine It’s normal for the transmission fluid temperature to
vary, depending on the type of driving you do and
weather conditions. If you drive on long grades on a hot
day, the transmission fluid temperature will be higher
than normal driving on a cold day. If you drive your
Corvette at high speeds with a lot of stop-and-go or fast
accelerations, your transmission fluid temperature may
also be higher.
If the transmission fluid exceeds
280°F (138 “C), the
CHECK GAUGES light will come on and HI
AUTO
will be displayed next to the transmission fluid
temperature when you toggle through the GAUGES
button. You should move the shift lever to DRIVE (D)
and continue driving at a slower, constant speed.
Monitor the transmission fluid temperature and allow
it
to cool to 180°F (82°C) to 200°F (93°C). Then, you
should check the transmission fluid level for a low fill or
overfill condition and bring your Corvette in for service
as soon as possible (see “Automatic Transmission Fluid”
in the Index). Also, check the engine coolant
temperature. If it’s too hot, see “Cooling System” in the
Index.
Check Gauges Light
This red light will come on
briefly when you are
starting the engine. If the
light comes on and stays on
while
you are driving, check
your gauges to see if they
are
in the warning areas.
This light can come
on for:
0 high engine oil temperature or low oil pressure
high coolant temperature
high or low battery voltage
0 low fuel level
0 high automatic transmission oil temperature
