Downloaded from www.Manualslib.com manuals search engine Avoid needless heavy braking. Some people drive
in spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. 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
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system will check itself.
You may
hear a momentary motor or clicking noise while this test
is going on, and you may even notice that your brake
pedal moves a little. This is normal.
SERVICE
If there’s a problem with the
anti-lock brake system, this
warning light will stay on.
See “Anti-Lock Brake
System Warning Light” in
the Index.

ASR
This warning light will
come on to let you know if
there’s a problem with your
ASR system. See “ASR
System Warning Light” in
the Index.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly. (The ASR
OFF light will also come on when the ASR system
warning light comes on.)
The ASR system automatically comes on whenever you
start your vehicle.
To limit wheel spin, especially in
I slippery road conditions, you should always leave the
system on. But you can
turn the ASR system off if you
ever need to. (You should turn the system off if your
vehicle ever gets stuck in sand, mud, ice or snow. See
“Rocking Your Vehicle” in the Index.) To
turn the system off, press the button located
above-the
headlamp switch. The ASR
OFF light will come on and
stay on.
If the ASR system is limiting wheel spin when
you press the button,
the system will turn off right away.
You can turn the system back on at any time by pressing
the button again. The ASR
OFF light should go off.
Braking in Emergencies
Use your anti-lock braking system when you need to.
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.

One of the biggest problems with city streets is the
amount of traffic on them. You’ll want to watch
out for
what the other drivers are doing and pay attention to
traffic signals. Here are
ways to increase your safety in city driving:
0 Know the best way to get to where you are
going. Get a city map and plan your trip into an
unknown part of the city just as
you would for a
cross-country trip.
0 Try to use the freeways that rim and crisscross most
large cities. You’ll save time and energy. (See the
next part, “Freeway Driving.”)

Here are some tips for winter driving:
0 Have your Corvette in good shape for winter.
0 You may want to put winter emergency supplies in
your vehicle. Include
an ice scraper, a small brush or broom,
a supply
of windshield washer
fluid, a rag, some winter outer
clothing, a small shovel, a flashlight, a red cloth and a
couple of reflective warning triangles. And,
if you will
be driving under severe conditions, include a small bag
of sand, a piece of old carpet or a couple of burlap bags
to help provide traction. Be sure you properly secure
these items in your vehicle.

Downloaded from www.Manualslib.com manuals search engine . When to Change Engine Oil
If any one of these is true for you, use the short tripkity
maintenance schedule:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
Driving under these conditions causes engine oil to break
down sooner.
If any one of these is true for your vehicle,
you need to change your oil and filter every
3,000 miles
(5 OOO km) or 3 months -- whichever occurs first.
If none of them is true, use the long triphighway
maintenance schedule. Change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
occurs first. Driving a vehicle with a fully warmed
engine under highway conditions causes engine oil to
break down slower.
Your Corvette has an Oil Life Monitor. This featwe will
let you know when to change your
oil and filter -- usually
between
3,000 miles (5 O00 krn) 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 (whichever
occurs first) 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. Remember to reset the monitor when the
oil has been changed. For more information, see
“Engine Oil Life Monitor”
in the Index.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may
be unhealthy for your skin and could
even cause cancer? Don’t let used oil stay on your
skin for
very long. Clean your skin and nails with soap and water,
or a good hand cleaner. Wash or throw away clothing or
rags containing used engine
oil. (See the manufacturer’s
warnings about the use and disposal of oil products.)
Used oil can be a real threat to the environment. If you
change your own oil, be sure to
drain all free-flowing oil
from the filter before disposal. Don’t ever dispose of oil by
putting it in the trash, pouring it on the ground, into
sewers, or into
streams or bodies of water. Instead, recycle
it by taking it to a place that collects used oil.
If you have
a problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help\

Downloaded from www.Manualslib.com manuals search engine What to Use
To add lubricant when the level is low, use Axle
Lubricant (GM
Part No. 12345977) or SAE SOW-90
GL-5 gear lubricant.
To completely refill after draining,
add 4 ounces
(1 18 ml) of Limited-Slip Differential
Lubricant Additive (GM Part
No. 1052358). Then fill to
the bottom
of the filler plug hole with Axle Lubricant
(GM
Part No. 12345977) or SAE SOW-90 GL-5 gear
lubricant.
Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL (orange-colored, silicate-free) engine
coolant. This coolant is designed
to remain in your
vehicle for
5 years or 100,000 miles (166 000 km),
whichever occurs first.
The following explains your cooling system and how
to
add coolant when it is low. If you have a problem with
engine overheating or
if you need to add coolant to
your high fill reservoir, see “Engine Overheating”
in the Index.
A 50/50 mixture of water and the proper coolant for
your Corvette will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265 OF ( 129 O C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
0 Let the warning lights and gauges work as they should.
NOTICE:
When adding coolant it is important that you use
DEX-COOL (orange-colored, silicate-free)
coolant meeting GM Specification 6277M.
If
silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engine
coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first.

Downloaded from www.Manualslib.com manuals search engine Brake Wear
Your Corvette has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched warning sound when the brake pads
are
worn and new pads are needed. The sound may come
and go or be heard all the time your vehicle is moving
(except when you
are pushing on the brake pedal
firmly).
I A CAUTION:
The brake wear warning sound means that
sooner or later your brakes won’t work well.
That could lead to an accident. When you hear
-.he brake wear warning sound, have your vehicle
I serviced*
NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.
Brake linings should always be replaced as complete
axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or
if there is a rapid increase in pedal
travel. This could be a sign of brake trouble.
Brake Adjustment
As you make brake stops, your disc brakes
automatically adjust for wear.

Downloaded from www.Manualslib.com manuals search engine Extended Mobility Tires (Option)
If your Corvette has optional Goodyear Extended
Mobility Tires
(EMT’s), the tires will have “EMT”
molded on the sidewalls. Your vehicle may also have a
spare tire delete option. With the spare tire delete option,
there’s no spare tire,
no tire changing equipment and no
place to store
a tire in the vehicle. Extended Mobility
Tires perform
so well without any air that a Low Tire
Pressure Warning System (LTPWS) is used to alert you
if a tire has lost pressure. A LOWFLAT TIRE light will
appear on your Driver Information Center if a tire’s
inflation pressure is less than
25 psi (170 kPa). If the
LOWFLAT TIRE light comes
on, check your tire
pressures as soon as you can. See
“Low Tire Pressure
Warning Light” in the Index for additional information.
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 1 ,
55 mph (90 kmh) when the LOWLFLAT TIRE
warning light
is on. Drive cautiously, and check
your tire pressures as soon as you can.

Downloaded from www.Manualslib.com manuals search engine Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance. (This
applies only to vehicles sold in the United States.) The
grades are molded on the sidewalls
of most passenger
car tires. The Uniform Tire Quality Grading system does
not apply to deep tread, winter-type snow tires,
space-saver or temporary
use spare tires, tires with
nominal rim diameters of 10 to 12 inches (25 to
30 cm),
or to some limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may
vary with respect to these
grades, they must also conform to Federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions 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 lowest, are A, B, and
C, and 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 (straightahead) 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 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.
