Brake Fluid
6
Your brake master cylinder reservoir is here. It is filled
with
DOT-3 brake fluid.
There are only two reasons why the brake fluid level in the
reservoir might
go down. The first is that the brake fluid
goes down to
an acceptable level during normal brake
lining wear. When new linings are put in, the fluid level
goes back up. The other reason is that fluid is leaking out
of the brake system. If it is, you should have your brake system fixed, since a leak means that
sooner or later your
brakes won't work well, or won't work at all.
So, it isn't a good idea to "top off' your brake fluid.
Adding brake fluid won't correct a
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.
A CAUTION:
If you have too much brake fluid, it can spill
on the engine. The fluid will burn if the engine
is hot enough. You
or others could be burned,
and
your vehicle could be damaged. Add brake
fluid only when work is done on the brake
hydraulic system.
Refer to the Maintenance Schedule to determine when to
check your brake fluid. See "Periodic Maintenance
Inspections" in the Index.

Downloaded from www.Manualslib.com manuals search engine Checking Brake Fluid
You can check the brake fluid without taking off the cap. NOTICE:
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.
What to Add
When you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme ll@ (GM Part
No. 12377967). Use new brake fluid from a sealed
container only.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This will help keep
dirt from entering the reservoir.
With the wrong kind of fluid in your b,,ke
system, your brakes may not work well, or they
may not even work at all. This could cause
a
crash. Always use the proper brake fluid.
0 Using the wrong fluid can badly damage
brake system parts. For example, just
a few
drops
of mineral-based oil, such as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind of fluid.
0 If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on your vehicle.
If you do, wash it off
immediately. See “Appearance Care”
in the Index.

Your new Corvette comes with high-quality tires made
by a leading tire manufacturer. If you ever have
questions about your tire warranty and where to obtain
service, see your Corvette Warranty booklet for details.
Poorly maintained and improperly used tires are
dangerous.
0 Overloading your tires can cause
overheating as a result of too much friction.
You could have an air-out and a serious
accident. See “Loading Your Vehicle”
in the Index.

Underinflated tires
pose the same danger as
overloaded tires. The resulting accident could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
Overinflated tires are more likely to be
cut, punctured or broken by a sudden
impact
-- such as when you hit a pothole.
Keep tires
at the recommended pressure.
Worn, old tires can cause accidents.
If your
tread is badly worn, or if your tires have
been damaged, replace them.

high-speed driving.

Downloaded from www.Manualslib.com manuals search engine Extended Mobility Tires
Your Corvette, when new, had Goodyear Extended
Mobility Tires (EMT). 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 Tire Pressure Monitor (TPM) is
used to alert you if a tire has lost pressure.
The Tire Pressure Monitor (TPM) has a sensor on
each road wheel that transmits to a receiver on the
instrument panel.
The system operates on a radio frequency subject to
Federal Communications Commission (FCC) Rules and with Industry and Science Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1)
this device may not cause harmful interference, and
(2) this device must accept any interference received,
including interference that may cause undesired operation.
This device complies with RSS-210 of Industry and
Science Canada. Operation is subject to the following
two conditions:
(1) this device may not cause
interference, and (2) this device must accept any
interference received, including interference that may
cause undesired operation of the device. Changes
or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
If a tire’s inflation pressure is between
5 psi (35 kPa)
and 25 psi
(170 kPa), you will see a message on the
Driver Information Center. This message will show
which tire is underinflated and two chimes will sound.
An example would be LOW TIRE PRESSURE-LR.
This would mean that the inflation pressure in your left
rear tire is between
5 psi (35 Pa) and 25 psi (170 Wa).
If the inflation pressure in the tire drops below
5 psi
(35 kPa), the message would read FLAT TIRE-LR and
four chimes will sound. See “Driver Information
Center” in the Index.
The TPM will also alert you if a tire’s pressure is higher
than 42 psi (290 kPa). The message will show which tire
is overinflated and two chimes will sound. An example
would be
HIGH PRESSURE-LR. This would mean that
the inflation pressure in your left rear tire is higher than
42 psi
(290 Wa). See “Driver Information Center” in
the Index.
If a tire pressure message appears
on the Driver
Information Center, stop as soon as you can. Have the
tire pressures checked and set to those shown on your
Tire Loading Information label.

9 CAUTION:
When the LOW TIRE PRESSURE or FLAT TIRE message is displayed on the Driver
Information Center, 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 LOW TIRE PRESSURE or FLAT TIRE
message is displayed. Drive cautiously, and check
your tire pressures as soon as you can.
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
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 kdh), but the tire would then have to be
replaced. When a tire is filled with air,
it provides a
cushion between the road and the wheel. Because you
won’t 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 even before you’ve driven
on the tire in a deflated condition. When a tire has
been damaged, or if you’ve driven any distance on
a
deflated EMT, check with an authorized 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.
As soon as possible,
contact the nearest authorized Chevrolet or Goodyear
EMT servicing facility for inspection and repair or
replacement. Call Chevrolet at 1-800-CHEV-USA
(1-800-243-8872) or Goodyear at 1-800-789-9878
24-hours a day for information on the location of the
nearest EMT servicing facility. In Canada, contact the
Customer Communication Center at 1-800-263-3777, or
Canadian Roadside Assistance at 1-800-268-6800. You
can also use the Goodyear number listed above to locate
an authorized EMT servicing facility.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
Don’t let anyone tell you that underinflation or
overinflation
is all right. It’s not. If your tires
don’t have enough air (underinflation), you can
get the following:
0 Too much flexing
0 Too much heat
0 Tire overloading
0 Bad wear
Bad handling
0 Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
0 Bad handling
Rough ride
0 Needless damage from road hazards. When to Check
Check your tires
once a month or more.
How to Check
Use a good quality pocket-type gage to check tire
pressure.
You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure
to put the valve caps back on the valve stems.
They help prevent leaks by keeping out
dirt and moisture.
Tire Rotation
The tires on your Corvette are directional 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.

Downloaded from www.Manualslib.com manuals search engine 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 need
a new tire if any of the following statements
are true:
You can see the indicators at three or more places
You can see cord or fabric showing through the
around the tire.
tire’s rubber.
The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
The tire has a bump, bulge or split.
The tire has a puncture, cut or other damage that
can’t be repaired well because of the size or location
of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at
the Tire-Loading Information label.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire’s sidewall. When you get new tires,
get ones with that same TPC Spec number. That way
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service on
your vehicle.
If your tires have an all-season tread
design, the TPC number will be followed by an
“MS”
(for mud and snow).

Keep belts clean and dry.
Do not bleach or dye safety belts. If you do, it
may severely weaken them. In a crash, they
might not
be able to provide adequate protection.
Clean safety belts only with mild soap and
lukewarm water.
Cleaning Glass Surfaces
Glass should be cleaned often. GM Glass Cleaner (GM
Part No. 1050427) or a liquid household glass cleaner
will remove normal tobacco smoke and dust films on
interior glass.
Don’t use abrasive cleaners on glass, because they may
cause scratches. Avoid placing decals on the inside rear
window, since they may have to be scraped
off later. If
abrasive cleaners are used on the inside of
the rear
window, an electric defogger element may be damaged.
Any temporary license should not be attached across the defogger grid.
Cleaning the Outside of the
Windshield and Wiper Blades
If the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running,
wax, sap or other material may be on the blade
or windshield.
Clean the outside of the windshield with GM
Windshield Cleaner, Bon
Ami@ Powder (non-scratching
glass cleaning 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 damage the panel.
Grime
horn the windshield will stick to the wiper blades
and affect their performance. Clean the blade by wiping
vigorously with a cloth
soaked in full-strength windshield
washer solvent. Then rinse the blade
with water.
Check the wiper blades and clean them as necessary;
replace blades that look worn.
