gauge reads half full, but it took more
(or less) than half of the tank’s
capacity to fill it.
The gauge moves a little when you
turn, stop or speed up.
You can use the Trip Monitor to display
more detailed fuel information. Each time
you press “FUEL INFO,” one

Brake System Warning Light
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 as you start thc
vehicle. If it doesn’t come on then, have
it fixed
so it will be ready to warn you if
there’s a problem. If this warning light
stays on, there could be
a brake problem.
Have your brake system inspected right
away.
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

With anti-lock, this light will come on
when you start your engine and may stay

If the light doesn’t come on, have it fixed
so it will be ready to warn you if there is i
problem.
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

You can still drive, but you should see
your dealer soon.
The Selective Ride Control system is
designed to sense vehicle speed in the
first minute after the vehicle is started.
If the vehicle is not moved
in that first
minute, the system records a fault. The

If you need to add more coolant, add the
proper mix at
the coolant recovery tank,
but only when your engine is cool. If the
tank is very low or empty, also add
coolant to the coolant high fill reservoir.
See “Engine Overheating”
in the Index
for information.
. . .190
Add coolant mix at the recovery tank, but
be careful not to spill it.
NOTICE:
You can be burned if you spill coolant
on hot engine parts. Coolant contains
ethylene glycol, and it will burn if the
engine parts are hot enough. Don’t
spill coolant on a hot engine.
For complete drain, flush and refill
of
the engine, contact your Chevrolet
jealer or the procedure may be found in
3 Chevrolet Corvette Service Manual. To
purchase a service manual, see “Service
Publications” in the Index.
Thermostat
Engine coolant temperature is controlled
by a thermostat in
the engine coolant
system. The thermostat stops the flow of
coolant through the radiator until the
coolant reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.

on a specified government test course. For
example, a tire graded 150 would wear
one and a half
(1 1/2) times as well on the
government course as a tire graded
100.
The relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly
from the norm due to variations in driving
habits, service practices and differences in
road characteristics and climate.
Traction - A, B, C
The traction grades, from highest to
iowest are:
A, B, and C. They represent
the tire’s ability to stop on wet pavement
as measured under controlled conditions
on specified government test surfaces of
asphalt and concrete.
A tire marked C
may have poor traction performance.
Warning: The traction grade assigned
to this tire is based on braking
(straight-ahead) traction tests and does
not include cornering (turning) traction.
Temperature - A, B, C
The temperature grades are A (the
highest),
B, and C, representing the tire’s
resistance to the generation of heat and its
ability to dissipate heat when tested under
controlled conditions on a specified
. . .208
indoor laboratory test wheel. Sustained
high temperature can cause the material
of the tire to degenerate and reduce tire
life, and excessive temperature can lead to
sudden tire failure. The grade C
corresponds to a level
of performance
which all passenger car tires must meet
under the Federal Motor Vehicle Safety
Standard
No. 109. Grades B and A
represent higher levels of performance on
the laboratory test wheel than the
minimum required by law.
Warning: The temperature grade for
this tire is established for a tire that is
properly inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either separately or
in combination, can cause heat buiidup
and possible tire failure.
These grades are molded on the sidewalls
of passenger car tires.
While the tires available as standard or
optional equipment on General Motors
vehicles may vary with respect to these
grades, all such tires meet General Motors
performance standards and have been
approved for use on General Motors
vehicles. All passenger type
(P Metric)
tires must conform to Federal safety
requirements in addition to these grades.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned
and balanced carefully at the factory to
give you the longest tire life and best
overall performance.
In most cases, you will not need to have
your wheels aligned again. However, if
you notice unusual tire wear or your
vehicle pulling one way or
the other, the
alignment may need to be reset. If you
notice your vehicle vibrating when
driving on a smooth road, your wheels may need to be rebalanced.
Wheel- Replacement - . -
Replace any wheel that is bent, cracked or
badly rusted. If wheel nuts keep coming
loose, the wheel, wheel bolts, and wheel
nuts should be replaced. If the wheel
leaks air, replace it (except some
aluminum wheels, which can sometimes
be repaired). See your Chevrolet dealer
if any of these conditions exist.
Your dealer will know the kind of wheel
you need.
Each new wheel should have the same
load carrying capacity, diameter, width,
offset, and be mounted
the same way as
the one it replaces.

To determine the preferred
viscosity for your vehicle’s
engine (e.g.,
SAE 5W-30 or SAE
10W-30), see “Engine Oil” in
the Index.
Your vehicle has an Engine Oil
Life Monitor. This monitor will
show you when to change the oil
- usually between 3,000 miles
(5 000 km) and 7,500 miles
( 12 500 km) since your last oil
change. Under severe conditions
the indicator may come on before
3,000 miles
(5 000 km). Never
drive your vehicle more than
7,500 miles (12
500 km) or 12
months without an oil change.
The system won’t detect dust in
the oil..
So if you drive in a dusty
area be sure
to change your oil
every 3,000 miles
(5 000 km) or
sooner if the “Change Oil” light
comes on.
