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 when you turn the
ignition key to START.
If
it doesn’t come on then,
have it fixed

ready to warn you if there’s
a problem. 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 closer to the floor.
It may take longer to stop. If the light is still on, have the
vehicle towed for service. (See “Towing Your Vehicle”

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 anti-lock brake system warning light should come
on briefly when you turn the ignition key to
RUN.

Driving with the LOW COOLANT light on
could cause your Corvette to overheat. See
“Engine Overheating” in the Index. Your
Corvette could be damaged and it wouldn’t be
covered by your warranty.
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.
LOW/FLAT
TI RE
The LTPWS monitors air
pressure in each road tire
while you’re driving your
Corvette. The LOWELAT
TIRE light will come on
whenever tire pressure in
any road tire goes below
25 psi (170 kPa), and it will
stay on until
you turn off
the ignition.
2-83

Downloaded from www.Manualslib.com manuals search engine The light may come on if any LTPWS parts aren’t
working properly.
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 LOWELAT 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.
I
When the LOWELAT TIRE warning light is on,
your vehicle’s handling capabilities will be
reduced during severe maneuvers.
If you drive
too fast, you could lose control of your vehicle.
You or others could be injured. Don”t drive over
55 mph (90 km/h) when the LOWWLAT TIRE
warning light is on. Drive cautiously, and check
your tire pressures as soon
as you can.
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
1996 Corvette Service Manual for correct tire mounting
and dismounting procedures.
The LOW/FLAT 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.

Downloaded from www.Manualslib.com manuals search engine Service LTPWS Light (Option)
SERVICE
LTPWS
The 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 kmh) 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 not indicate that anything is wrong with
your Corvette.
0 You turn the ignition on three times in a row within
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.
0 You run your Corvette three times within 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.

monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD I1 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the life
of the vehicle, helping to produce a cleaner
environment. (In Canada, OBD I1 is replaced by
Enhanced Diagnostics.) The SERVICE ENGINE
SOON
light comes on to indicate that there is a problem and
service is required. Malfunctions often will be indicated
by the system before any problem is apparent, which
may prevent more serious damage to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls won’t
work as well, your fuel economy won’t be as good
and your engine may not run as smoothly. This
could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine
is not
running. If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
0
0 Light Flashing -- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.
2-86

Downloaded from www.Manualslib.com manuals search engine If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you just put fuel into your vehicle?
If
so, reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system can determine if the fuel
cap has been left
off or improperly installed. This will
allow fuel to evaporate into the atmosphere.
A few
driving trips should turn the light
off.
Did you just drive through a deep puddle of water?
If
so, your electrical system may be wet. The condition
will usually
be corrected when the electrical system
dries out. A few driving trips should turn the light
off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly. It
will take a few driving trips to turn the light
off.
Reduce vehicle speed.
Avoid hard accelerations.
0 Avoid steep uphill grades.
If the light stops flashing and remains
on steady see “If
the Light Is On Steady” following.
If
the light continues to flash, when it is safe to do so,
stop the vehicle. Put your vehicle in PARK (P). Turn the
key off,
wait at least 10 seconds and restart the engine.
If the light remains on steady, see “If the Light Is On
Steady” following. If the light is still flashing follow the
previous steps, and drive the vehicle to your dealer or
qualified service center for service.
