Your passenger’s side mirror is convex. A convex
mirror’s surface is curved
so you can see more from the
driver’s seat.
A CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut
too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder before
changing lanes.
Each door has a storage compartment below the armrest
which can be accessed
by lifting up on the armrest.

Downloaded from www.Manualslib.com manuals search engine 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 farniliar 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.
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.

Downloaded from www.Manualslib.com manuals search engine 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, the air bag modules,
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.
Charging System Indicator Light
-+I
This 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.

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. If you
must drive a short distance with the voltmeter
reading in a shaded area, turn
off all your accessories,
including your comfort controls and audio systems.
For numeric gauge
measurements, press the
GAUGES button on the
trip monitor until
VOLT

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.

Downloaded from www.Manualslib.com manuals search engine Malfunction Indicator Lamp (Service Engine Soon Light)
Your Corvette is equipped
with a.computer which
SERVICE
SOON
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.

Downloaded from www.Manualslib.com manuals search engine Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor
fuel quality will cause your
engine not to run as efficiently as designed.
You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience this condition, change the fuel brand
you use. It will require at least one full tank of the
proper fuel to turn the light
off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.

This light should come on
while you are starting your
engine.
If the light doesn’t

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 Wa).
(In certain situations such as long, extended idles on hot
days, it could read as low as
6 psi (40 kPa) and still be
considered normal.) 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.
A CAUTIOh:
Don’t keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
