leak. If you add fluid when your linings
are worn, then
you’ll have too much fluid when
you get new brake
linings. You should add (or remove) brake fluid, as
necessary, only when work is done on the brake
hydraulic system. On
vehicles equipped with the
LT5 (Code J) engine, the
brake warning light will come on when your brake fluid
falls to a low level. See “Brake System Warning Light”
in the Index.
For vehicles equipped with the
LT1 (Code P) engine,
refer to the Maintenance Schedule to determine when to
check your brake fluid. See “Periodic Maintenance
Inspections” in the Index.
To Check Brake Fluid
You can check the brake fluid without taking off the cap.
Just look at the brake fluid reservoir.
The fluid level
should be above the MIN mark on the reservoir. If it
isn’t, have your brake system checked to see
if there is
a leak.
After work is done on the brake hydraulic system, make
sure the level is between the MIN and MAX
marks.

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 LOWELAT TIRE light will
appear on your Driver Information Center
if a tire’s
inflation pressure is less than
25 psi (170 kPa). If the
LOW/FLAT
TIRE light comes on, check your tire
pressures as soon as you can. See “Low Tire Pressure
Warning System” in the Index for additional information. If a
tire goes flat,
you won’t need to stop on the side of
the road to change the tire. You can just keep on driving.
The shorter the distance
you drive and the slower the
speed, the greater the chance that the tire will not have
to be replaced. If
you drive on a deflated EMT for
distances
of 50 miles (80 km) or less and at speeds of
55 mph (90 km/h) or less, there is a good chance that the
tire can be repaired. The tire can operate effectively with
no air pressure for up to 200 miles (320 km) at speeds
up to
55 mph (90 kmk), but the tire would then have to
be replaced. Also remember: When a tire is filled with
air, it provides a cushion between the road and the
wheel. Because you do not have this cushion when
driving on a deflated tire, try to avoid potholes that
could damage your wheel and require replacement of it.
Some road hazards can damage a tire beyond repair. This
damage could occur before you’ve driven on the tire
in a
deflated condition. Whenever a tire has been damaged, or
if you’ve driven any distance on a deflated EMT, check
with a Goodyear EMT Service Center to determine
whether
the tire can be repaired or should be replaced.
To maintain your vehicle’s extended mobility feature,
all replacement tires must be Extended Mobility Tires.
See the Goodyear Extended Mobility Tire Owner’s
Manual and Limited Warranty supplied with your
Corvette for additional information.

Downloaded from www.Manualslib.com manuals search engine Inflation - Tire Pressure
The Tire-Loading Information label which is on the
driver’s door shows the correct inflation pressures for
your tires, when they’re cold. “Cold” means your
vehicle has been sitting for at least three hours or driven
no more than a mile.
For competitive driving or high-speed driving (over
150 mph or 240 km/h), make sure your tires are inflated
to
35 psi (240 Wa). When you end this type of driving,
reduce the “cold” inflation pressures
(if necessary) to
those listed on the Tire-Loading Information label.

I NOTICE:
Don’t let anyone tell you that underinflation or
overidation is
all right. It’s not. If your tires don’t
have enough
air (underinflation) you can get:
Too much flexing

Tire overloading
Bad wear

When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 Wa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. Simply looking at the tires will not tell you the
pressure, especially if you have radial tires
-- which
may look properly inflated even if they’re underinflated.
If your tires have valve caps, be sure to put them back
on. They help prevent leaks by keeping out dirt and
moisture.

The tires on your Corvette are directional, asymmetrical,
and are different sizes front to rear. Due to this, your
tires should not be rotated. Each tire and wheel should
be used only in the position it is in.
When it’s Time for New Tires
One way to tell when it’s time for new tires is to check
the treadwear indicators, which will appear when your
tires have only
1/16 inch (1.6 mm) or less of tread
remaining. You

Windshield and Wiper Blades
If the windshield is not clear after using the windshield
washer,
or if the wiper blade chatters when running, wax
or other material may be on the blade or windshield.
Clean the outside
of the windshield with GM
Windshield Cleaner, Bon-Ami Powder@ (GM
Part No.
1050011). The windshield is clean if beads do not form
when you rinse it with water.
If you use a glass treatment or conditioner containing
ethyl alcohol or ethyl sulfate on your glass, be sure to
remove the acrylic roof panel, if
so equipped. These
products may darnage the panel.
Clean the blade by wiping vigorously with a cloth
soaked in full strength windshield washer solvent. Then
rinse the blade with water.
Wiper blades should be checked on a regular basis and
replaced when worn.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth at least every six
months. During very cold, damp weather more frequent
application may be required. (See “Recommended
Fluids and Lubricants” in the Index.)
Cleaning a Removable Roof Panel
Special care is necessary when cleaning, removing
and/or storing the roof panel.
Flush with water to remove dust and dirt, then dry
the panel.
Clean the panel with GM Glass Cleaner. Leave the
cleaner on the panel for one minute, then wipe the
panel with a soft, lint-free cloth.
Don’t use abrasive cleaning materials.
If water drops are frequently allowed to dry on the roof
panel, impurities in the water will adhere to the top.
These impurities may destroy the finish. When the panel
gets wet, you should dry it o€f.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
Do not use a glass treatment or conditioner
containing ethyl alcohol or ethyl sulfate on the
roof panel. These products may damage the panel.
Cleaning the Outside of Your
Corvette
The paint finish on your vehicle provides beauty, depth
of color, gloss retention and durability.
Washing Your Vehicle
The best way to preserve your vehicle’s finish is to keep
it clean by washing it often with lukewarm or cold water.
Don’t wash your vehicle in the direct rays of the sun.
Don’t use strong soaps or chemical detergents. Use
liquid hand, dish
or car washing (mild detergent) soaps.
Don’t use cleaning agents that are petroleum based, or
that contain acid or abrasives. All cleaning agents
should be flushed promptly and not allowed
to dry on the surface,
or they could stain.
Dry the finish with a
soft, clean chamois
or a 100% cotton towel to avoid
surface scratches and water spotting.
High pressure car washes may cause water to enter
your
vehicle.
I 1
I NOTICE:
Conveyor systems on some automatic car washes
may damage
a Corvette. They may not have
enough clearance for the undercarriage
or for the
extra wide rear tires
on ZR-1 models.
Check with the manager before using a car wash.
Finish Care
Occasional waxing or mild polishing of your Corvette
by hand may be necessary to remove residue from the
paint finish. You can get
GM approved cleaning
products from your dealer. (See “Appearance Care and
Materials” in the Index.)

NOTICE:
Don’t add anything electrical to your Corvette
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your warranty. Some add-on electrical equipment can
keep other components from working as they
should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your Corvette, see “Servicing
Your Air Bag-Equipped Corvette” in the Index.
The wiring circuits in your vehicle are protected from
short circuits by a combination
of maxi-fuses,
mini-fuses, and circuit breakers. This greatly reduces the
chance
of fires caused by electrical problems.
6-67

Downloaded from www.Manualslib.com manuals search engine There are three fuse centers on your vehicle. One is in
the right side of your instrument panel. Turn the knob
and pull the door to access the fuses.
The other two fuse blocks are in the engine
compartment. One
is part of the Forward Lamp wiring
harness
(A), and the other is part of the ECM-Engine
wiring harness
(B).
Look at the silver-colored band inside the fuse. If the
band
is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one
of the correct size.
If you ever have a problem on the road and don’t have a
spare fuse, you can borrow one of the correct value. Just
pick some feature
of your vehicle that you can get along
without
-- like the radio or cigarette lighter -- and use
its fuse, if it is the size you need. Replace it as soon as
you can.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the switch. An electrical overload will cause the lamps
to
go on and off, or in some cases to remain off. If this
happens, have your headlamp wiring checked right
away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker and a
fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools. If
the overload is caused by some electrical problem and
not snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load is too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is fixed or goes away.

The remainder of this section is divided into five parts:
“Part A: Scheduled Maintenance Services” shows
what
to have done and how often. Some of these
services can be complex,
so unless you are technically
qualified and have the necessary equipment, you should
let your dealer’s service department
or another qualified
service center do these jobs.
If you are skilled enough to do some work on your
i vehicle, you will probably want to get the service

“Part B: Owner Checks and Services” tells you what
should be checked whenever you stop for fuel. It also
explains what you can easily do to help keep your
vehicle in good condition.
“Part C: Periodic Maintenance Inspections” explains
important inspections that your Chevrolet dealer’s
service department or another qualified service center
should perform.
“Part D: Recommended Fluids and Lubricants” lists
some products
GM recommends to help keep your
vehicle properly maintained. These products, or their
equivalents, should be used whether you do the work
yourself or have it done.
“Part E: Maintenance Record’’ provides a place for
you to record the maintenance performed on your
vehicle. Whenever any maintenance is performed, be
sure to write it down
in this part. This will help you
determine when your next maintenance should be done.
In addition, it is a good idea to keep your maintenance
receipts. They may be needed to qualify your vehicle for
warranty repairs.
