come on every time you
turn the
ignition on until you move your
Corvette.

row for half an hour while all four
sensors are missing. (All the sensors
would be missing, for example, if yo,u

without transferring the sensors.)
If you would like to clear the
”SERVICE LTPWS” light from your
driver information center permanently,
see your dealer.
[f the light comes on and stays on, even
when the vehicle is driven, there may be a
problem with LTPWS. See your dealer.

your vehicle under normal driving
conditions, you should pull off the road,
stop your vehicle and turn off the engine

Malfunction Indicator Lamp (Service Engine Soon Light)
A computer monitors operation of your
fuel, ignition and emission control
systems. This 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.
NOTICE:
If you keep driving your vehicle
with this light on, after a while the
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 not covered by your warranty.

Engine Oil Pressure Gauge
This gauge tells you if there could be a
problem with your engine oil pressure.
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 kPa).
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.

Care of Your Compact Discs
Handle discs carefully. Store them in theil
original cases or other protective cases
and away from direct sunlight and dust.
U
the surface of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral
detergent solution and clean it, wiping
from the center to
the edge.
Be sure never to touch the signal surface
when handling discs. Pick up discs by
grasping the outer edges or the edge of
the
hole and the outer edge.
Power Antenna Mast Care
Your power antenna will look its best and
work well if it’s cleaned from time to
time.
To clean the antenna mast:
1. Turn on the radio to raise the antenna.
2. Dampen a clean cloth with mineral
spirits or an equivalent solvent.
3. Wipe the cloth over the mast, removing any dirt.
4. Wipe the mast dry with a clean cloth.
5. Turn the radio off and on to make the
antenna go down and up.
If the antenna is still dirty, repeat the steps.

Downloaded from www.Manualslib.com manuals search engine This is a mistake. Your brakes may not
have time to cool between hard stops.
Your brakes will wear out much faster if
you do a lot
of heavy braking. If you keep
pace with the traffic and allow realistic
following distances, you will eliminate a
lot of unnecessary braking. That means
better braking and longer brake life.
If your engine ever stops while you’re
driving, brake normally but don’t pump
your brakes. If you do, the pedal may get
harder to push down. If your engine stops,
you will still have some power brake
assist. But you will use it
when you brake.
Once the power assist is used up, it may
take longer to stop and the brake pedal
will be harder to push.

Anti-Lock Brakes (ABS)
Your Corvette has an advanced electronic
braking system that will help prevent
skidding.
This light on the instrument panel will go
on when you start your vehicle.
When you start your vehicle and begin to
drive away, you may hear a momentary
motor or clicking noise. And you may
even notice that your brake pedal moves
,
little while this is going on. This is the
ABS system testing itself. If there’s a
problem with the anti-lock brake system,
the anti-lock brake system warning light
will stay on.
See “Anti-lock Brake System Warning
Light” in the Index. Here’s how anti-lock works. Let’s, say
the road
is wet. You’re driving safely.

could. The computer is programmed to
