Engine Oil
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0237. .
Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil (Except
ZR1, Z06, Grand Sport, and
Stingray with Z51)
If the ENGINE OIL LOW–ADD OIL
message displays on the Driver
Information Center (DIC), check the
engine oil level right away.
Check the engine oil level regularly,
every 650 km (400 mi), especially
prior to a long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview
0225 for the location.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.

Caution (Continued)
.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.
. 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
Brake Wear
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 can come and go or be
heard all the time 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 pads could result in costly
brake repair.
Under certain weather or operating
conditions, occasional brake squeal
might be heard with the vehicle's
performance braking system. This
brake system is designed for
superior fade resistance and
consistent operation using high performance brake pads. Brake
squeal is normal and does not affect
system performance.
If equipped with high performance
brake linings, there could be an
increased build-up of brake dust as
well as minor noises as compared
to standard brake linings.
Brake linings should always be
replaced as complete axle sets.
Brake Wear (ZR1, Z06, and Grand
Sport with J57 Ceramic Brakes)
This vehicle does not have built-in
brake pad wear indicators. Periodic
visual inspection is required to
determine when to replace the
brake pads.
The ZR1, Z06, and Grand Sport
Coupe with J57 models also have
an electronic brake pad wear sensor
system. When pads are worn, the
CHANGE BRAKE PADS message
displays in the Driver Information
Center. Some driving conditions or
climates can cause a brake squeal
when the brakes are first applied or

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12032182) - 2019 - crc - 5/8/18
250 Vehicle Care
lightly applied. Brake linings should
always be replaced as complete
axle sets.
Brake Rotor Wear
ZR1, Z06, and Grand Sport models
may have ceramic brake rotors.
Rotors should be visually inspected
whenever the brake pads are
replaced. Rotors also need to be
weighed before brake pads are
replaced to confirm that the rotor
mass is greater than the wear-out
mass printed on then rotor. The
rotor can be reused if the weight of
the rotor is above the mass limit.
Rotor inspection and weighing
methods can be found in the service
manual.
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
that brake service may be required.
Replacing Brake System Parts
Always replace brake system parts
with new, approved replacement
parts. If this is not done, the brakes
may not work properly. The braking
performance expected can change
in many other ways if the wrong
replacement brake parts are
installed or parts are improperly
installed.
Cold Weather Brake Operation
High performance brake
components may bind and clunk
when moving the vehicle. This may
be noticeable after parking when the
brakes have been wet, such as
when driving in the rain or after a
car wash. This is normal for brakes
with high friction pads and does not
affect the operation of the brakes.
Apply the brakes several times until
the binding or clunking stops. Drive
the vehicle and apply the brakes
several times if it is washed before
long-term storage.
Brake Fluid
The brake/clutch master cylinder
reservoir is filled with GM approved
DOT 4 brake fluid as indicated on
the reservoir cap. SeeEngine
Compartment Overview 0225 for
the location of the reservoir.
Checking Brake Fluid
Place the vehicle in P (Park) or
Neutral with the parking brake
applied if equipped with a manual
transmission. On a level surface,
the brake fluid level should be
between the minimum and
maximum marks on the brake fluid
reservoir.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12032182) - 2019 - crc - 5/8/18
Vehicle Care 251
There are only two reasons why the
brake fluid level in the reservoir may
go down:
.Normal brake lining wear. When
new linings are installed, the
fluid level goes back up.
. A fluid leak in the brake/clutch
hydraulic system. Have the
brake/clutch hydraulic system
fixed. With a leak, the brakes will
not work well.
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it.
Do not top off the brake/clutch fluid.
Adding fluid does not correct a leak.
If fluid is added when the linings are
worn, there will be too much fluid
when new brake linings are
installed. Add or remove fluid, as
necessary, only when work is done
on the brake/clutch hydraulic
system.{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and
the vehicle could be damaged.
Add brake fluid only when work is
done on the brake/clutch
hydraulic system.
When the brake/clutch fluid falls to a
low level, the brake warning light
comes on. See Brake System
Warning Light 0115.
Brake fluid absorbs water over time
which degrades the effectiveness of
the brake fluid. Replace brake fluid
at the specified intervals to prevent
increased stopping distance. See
Maintenance Schedule 0312.
What to Add
Use only GM approved DOT 4
brake fluid from a clean, sealed
container. See Recommended
Fluids and Lubricants 0321.
{Warning
The wrong or contaminated brake
fluid could result in damage to the
brake system. This could result in
the loss of braking leading to a
possible injury. Always use the
proper GM approved brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces, the
paint finish can be damaged.
Immediately wash off any painted
surface.
Battery - North America
The original equipment battery is
maintenance free. Do not remove
the cap and do not add fluid.
Refer to the replacement number on
the original battery label when a
new battery is needed. For battery
replacement, see your dealer.

Vehicle Care 253
heard. A fluid loss could indicate a
problem. Have it inspected and
repaired.
How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface.
The fluid level should be at or within
13 mm (0.5 in) of the bottom of the
fill plug hole threads. If it is at this
level, no additional fluid is needed.
If the fluid level is below 13 mm
(0.5 in), add fluid until it is above
this level.
What to Use
To add lubricant when the level is
low or to completely refill after
draining, seeRecommended Fluids
and Lubricants 0321. Then fill to
within 13 mm (0.5 in) of the bottom
of the fill plug hole threads with the
required lubricant.
Starter Switch Check
{Warning
When you are doing this
inspection, the vehicle could
move suddenly. If the vehicle
moves, you or others could be
injured.
1. Before starting this check, be sure there is enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular brake.
See Electric Parking Brake
0 195. Do not use the accelerator
pedal, and be ready to turn off
the engine immediately if it
starts.
3. For automatic transmission vehicles, try to start the engine
in each gear. The vehicle
should start only in P (Park) or
N (Neutral). If the vehicle starts
in any other position, contact
your dealer for service.
For manual transmission
vehicles, put the shift lever in
Neutral, push the clutch pedal
down halfway, and try to start
the engine. The vehicle should
start only when the clutch
pedal is pushed down all the
way to the floor. If the vehicle
starts when the clutch pedal is
not pushed all the way down,
contact your dealer for service.

304 Vehicle Care
Replace the wiper blades if they are
worn or damaged. Damage can be
caused by extreme dusty
conditions, sand, salt, heat, sun,
snow, and ice.
Weatherstrips
Apply weatherstrip lubricant on
weatherstrips to make them last
longer, seal better, and not stick or
squeak. Lubricate weatherstrips at
least once a year. Hot, dry climates
require more frequent application.
Black marks from rubber material on
painted surfaces can be removed by
rubbing with a clean cloth. See
Recommended Fluids and
Lubricants0321.
Tires
Use a stiff brush with tire cleaner to
clean the tires.
Caution

or tires. When applying a tire
dressing, always wipe off any
overspray from all painted
surfaces on the vehicle.
Wheels and Wheel Trim
Use a soft, clean cloth with mild
soap and water to clean the wheels.
After rinsing thoroughly with clean
water, dry with a soft, clean towel.
A wax may then be applied.
Caution
Chrome wheels and chrome
wheel trim may be damaged if the
vehicle is not washed after driving
on roads that have been sprayed
with magnesium chloride or
calcium chloride. These are used
on roads for conditions such as
dust and ice. Always wash the
chrome with soap and water after
exposure.
Caution
To avoid surface damage on
wheels and wheel trim, do not
use strong soaps, chemicals,
abrasive polishes, cleaners,
or brushes. Use only GM
approved cleaners. Do not drive
the vehicle through an automatic
car wash that uses silicone
carbide tire/wheel cleaning
brushes. Damage could occur
and the repairs would not be
covered by the vehicle warranty.
Brake System
Visually inspect brake lines and
hoses for proper hook-up, binding,
leaks, cracks, chafing, etc. Inspect
disc brake pads for wear and rotors
for surface condition. Inspect drum
brake linings/shoes for wear or
cracks. Inspect other brake parts,
including drums, wheel cylinders,
calipers, parking brake, master
cylinder, brake fluid reservoir,
