Vehicle Care 257
Adding Washer Fluid
1. Open the hood. SeeHood017.
2. Open the cap with the washer symbol
on it. Add washer fluid until the tank
is full.
Caution
.Do not use washer fluid that contains
any type of water repellent coating.
This can cause the wiper blades to
chatter or skip.
.Do not use engine coolant (antifreeze)
in the windshield washer. It can
damage the windshield washer system
and paint.
.Do not mix water with ready-to-use
washer fluid. Water can cause the
solution to freeze and damage the
washer fluid tank and other parts of
the washer system.
(Continued)
Caution (Continued)
.When using concentrated washer fluid,
follow the manufacturer instructions
for adding water.
.Fill the washer fluid tank only
three-quarters full when it is very cold.
This allows for fluid expansion if
freezing occurs, which could damage
the tank if it is completely full.
Brakes
Disc brake linings have built-in wear
indicators that make a high-pitched warning
sound when the brake linings are worn and
new linings are needed. The sound can come
and go or can be heard all the time when
the vehicle is moving, except when applying
the brake pedal firmly.
{Warning
The brake wear warning sound means
that soon the brakes will not work well.
That could lead to a crash. When the
brake wear warning sound is heard, have
the vehicle serviced.
Caution
Continuing to drive with worn-out brake
linings could result in costly brake
repairs.
Properly torqued wheel nuts are necessary
to help prevent brake pulsation. When tires
are rotated, inspect brake linings for wear
and evenly tighten wheel nuts in the proper
sequence to torque specifications. See
Capacities and Specifications 0315.
Brake linings should be replaced as complete
axle sets.
Brake Squeal and Brake Dust
Some driving conditions or climates can
cause a brake squeal when the brakes are
first applied, clearing up following several
applies. This does not mean something is
wrong with the brakes.
Vehicles equipped with high performance
brake systems provide superior fade
resistance but will produce increased brake
squeal and brake dust on the wheels and
calipers as compared to standard brake
linings. This is normal.

Wheels and Tires
Tires
Every new GM vehicle has high-quality
tires made by a leading tire
manufacturer. See the warranty manual
for information regarding the tire
warranty and where to get service. For
additional information refer to the tire
manufacturer.
{Warning
.Poorly maintained and improperly
used tires are dangerous.
(Continued)
Warning (Continued)
.Overloading the tires can cause
overheating as a result of too
much flexing. There could be a
blowout and a serious crash. See
Vehicle Load Limits 0186.
.Underinflated tires pose the same
danger as overloaded tires. The
resulting crash could cause serious
injury. Check all tires frequently to
maintain the recommended
pressure. Tire pressure should be
checked when the tires are cold.
.Overinflated tires are more likely
to be cut, punctured, or broken by
a sudden impact —such as when
hitting a pothole. Keep tires at the
recommended pressure.
.Worn or old tires can cause a
crash. If the tread is badly worn,
replace them.
.Replace any tires that have been
damaged by impacts with
potholes, curbs, etc.

272 Vehicle Care
Warning (Continued)
.Improperly repaired tires can cause
a crash. Only your dealer or an
authorized tire service center
should repair, replace, dismount,
and mount the tires.
.Do not spin the tires in excess of
56 km/h (35 mph) on slippery
surfaces such as snow, mud, ice,
etc. Excessive spinning may cause
the tires to explode.
See Tire Pressure for High-Speed
Operation 0279 for inflation pressure
adjustment for high-speed driving.
All-Season Tires
This vehicle may come with all-season tires.
These tires are designed to provide good
overall performance on most road surfaces
and weather conditions. Original equipment
tires designed to GM's specific tire
performance criteria have a TPC specification
code molded onto the sidewall. Original
equipment all-season tires can be identified
by the last two characters of this TPC code,
which will be “MS.” Consider installing winter tires on the
vehicle if frequent driving on snow or
ice-covered roads is expected. All-season tires
provide adequate performance for most
winter driving conditions, but they may not
offer the same level of traction or
performance as winter tires on snow or
ice-covered roads. See
Winter Tires0272.
Winter Tires
This vehicle was not originally equipped
with winter tires. Winter tires are designed
for increased traction on snow and
ice-covered roads. Consider installing winter
tires on the vehicle if frequent driving on ice
or snow covered roads is expected. See your
dealer for details regarding winter tire
availability and proper tire selection. Also,
see Buying New Tires 0285.
With winter tires, there may be decreased
dry road traction, increased road noise, and
shorter tread life. After changing to winter
tires, be alert for changes in vehicle
handling and braking.
If using winter tires:
.Use tires of the same brand and tread
type on all four wheel positions.
.Use only radial ply tires of the same size,
load range, and speed rating as the
original equipment tires.
Winter tires with the same speed rating as
the original equipment tires may not be
available for H, V, W, Y, and ZR speed rated
tires. If winter tires with a lower speed
rating are chosen, never exceed the tire's
maximum speed capability.
Run-Flat Tires
This vehicle, when new, may have had
run-flat tires. There is no spare tire, no tire
changing equipment, and no place to store a
tire in the vehicle.
{Warning
While driving with run-flat tires at a
reduced inflation pressure, avoid making
sudden stops or severe maneuvers as the
handling capabilities of the tires will be
reduced. Driving too fast could cause loss
of control and you or others could be
injured. Do not drive over 80 km/h
(50 mph) with the tire operating at low
pressure. Drive cautiously and check the
tire pressure as soon as possible.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16287457) - 2023 - CRC - 3/10/22
Vehicle Care 273
Run-flat tires can be driven up to 80 km
(50 mi) at speeds less than 80 km/h
(50 mph) after a loss of inflation pressure
has occurred. There is no need to stop on
the side of the road to change the tire. The
possible driving range after a pressure loss
will vary based on the vehicle load and
driving conditions. As soon as possible,
contact the nearest authorized GM or
run-flat servicing facility for inspection and
repair or replacement.
When driving on a deflated run-flat tire,
avoid potholes and other road hazards that
could damage the tire and/or wheel beyond
repair. When a tire has been damaged, or if
driven any distance while deflated, check
with an authorized run-flat tire service
center to determine whether the tire can be
repaired or should be replaced. To maintain
the run-flat feature, all replacement tires
must be run-flat tires.
To locate the nearest GM or run-flat
servicing facility, call Customer Assistance.Low-Profile Tires
If the vehicle has 245/35ZR19,
305/30ZR20, 275/30ZR20, or 345/25ZR21
size tires, they are classified as
low-profile tires.Caution
Low-profile tires are more susceptible to
damage from road hazards or curb impact
than standard profile tires. Tire and/or
wheel assembly damage can occur when
coming into contact with road hazards
like potholes, or sharp edged objects,
or when sliding into a curb. The warranty
does not cover this type of damage. Keep
tires set to the correct inflation pressure
and when possible, avoid contact with
curbs, potholes, and other road hazards.
Competition Oriented Tires
This vehicle may come with 275/30ZR20 and
345/25ZR21, Michelin Pilot Sport Cup 2 R ZP,
competition oriented tires that are DOT
approved for street use. Competition
oriented tires use a special tread pattern
and compound that provide more grip than
normal road tires. The minimum tread depth
will be reached earlier than typical tires,
resulting in reduced tire life. This special
tread pattern and compound will have
decreased performance in cold climates,
heavy rain, and standing water. It is
recommended that winter tires be installed
on the vehicle when driving at temperatures
below approximately 10 °C (50 °F) or on ice
or snow covered roads.
{Warning
Driving on wet roads, in heavy rain,
or through standing water with
competition oriented tires may cause
hydroplaning and loss of control. Use
extreme caution and drive slowly on wet
roads.

16287457) - 2023 - CRC - 3/10/22
274 Vehicle Care
{Warning
Driving with competition oriented tires on
snow, ice, or cold road surfaces can cause
loss of control or a crash. Competition
oriented tires are summer season tires
and are not intended to be driven on
snow, ice, or road surfaces below 10 °C
(50 °F). Do not drive a vehicle with
competition oriented tires in these
conditions.
Caution
Competition oriented tires have rubber
compounds that lose flexibility and may
develop surface cracks in the tread area
at temperatures below−7 °C (20 °F).
Always store competition oriented tires
indoors and at temperatures above −7 °C
(20 °F) when not in use. If the tires have
been subjected to −7 °C (20 °F) or less, let
them warm up in a heated space to at
least 10 °C (50 °F) for 24 hours or more
before being installed or driving a vehicle
on which they are installed. Do not apply

Caution (Continued)
heat or blow heated air directly on the
tires. Always inspect tires before use. See
Tire Inspection 0283.
Summer Tires
High Performance Summer Tires
This vehicle may come with 245/35ZR19 and
305/30ZR20 Michelin Pilot Sport 4 S ZP or
275/30ZR20 and 345/25ZR21 Michelin Pilot
Sport 4 S ZP high performance summer tires.
These tires have a special tread and
compound that are optimized for maximum
dry and wet road performance. This special
tread and compound will have decreased
performance in cold climates, and on ice and
snow. It is recommended that winter tires
be installed on the vehicle if frequent
driving at temperatures below
approximately 5 °C (40 °F) or on ice or snow
covered roads is expected. See Winter Tires
0 272.
Caution
High performance summer tires have
rubber compounds that lose flexibility
and may develop surface cracks in the
tread area at temperatures below −7 °C
(20 °F). Always store high performance
summer tires indoors and at
temperatures above −7 °C (20 °F) when
not in use. If the tires have been
subjected to −7 °C (20 °F) or less, let them
warm up in a heated space to at least
5 °C (40 °F) for 24 hours or more before
being installed or driving a vehicle on
which they are installed. Do not apply
heat or blow heated air directly on the
tires. Always inspect tires before use. See
Tire Inspection 0283.
