continue to drive normally and have the
cooling system checked for proper fill and
function.
If the warning continues, pull over safely,
and park the vehicle right away.
If there is no sign of steam, idle the engine
for three minutes while parked. If the
warning is still displayed, turn off the
engine until it cools down.
Washer Fluid
What to Use
When the vehicle needs windshield washer
fluid, be sure to read the manufacturer
instructions before use. If the vehicle will be
operating in an area where the temperature
may fall below freezing, use a fluid that has
sufficient protection against freezing.
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.
.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 0325.

How to Reset the Brake Pad Life System
The system will automatically detect when
significantly worn brake pads are replaced.
When the ignition is turned on after new
pads and wear sensors are installed, a
message will display. Follow the prompts to
reset the system.
The brake pad life system can also be
manually reset:1. Display Brake Pad Life on the DIC. See Driver Information Center (DIC) 099.
2. Select the Brake Pad Life menu.
3. Select front or rear pads as appropriate.
4. Select YES on the confirmation message. Repeat for the pads on the other axle if
they were also replaced.
How to Disable the Brake Pad Life
System
The brake pad life system can be turned off.
This may be necessary if aftermarket brake
pads without wear sensors are installed.
When the system is turned off, the front
and rear brake pad life percentages will not
display. However, the built-in wear
indicators that make a high-pitched warning sound when the brake pads are worn can
still determine when the pads should be
replaced. See
Brakes0262.
To turn off the brake pad life system: 1. Display Brake Pad Life on the DIC. See Driver Information Center (DIC) 099.
2. Select the Brake Pad Life menu.
3. Select DISABLE.
To turn the brake pad life system back on,
follow the above steps but select ENABLE in
Step 2.
Electronic Brake Pad Sensor System
(Z06/Z07/E-Ray with J57 Carbon Ceramic
Brake Rotors)
The brake pads have electronic brake pad
wear sensors, when the brake pads need to
be replaced, a message displays in the
Driver Information Center (DIC) which says
“Service Brakes Worn”.
When the message displays, install new
brake pads and brake pad wear sensors on
the vehicle.
When the ignition is turned on after new
brake pads and brake pad wear sensors are
installed, the message should no longer
display. The brake pad sensor system can only be
reset by replacing the brake pads and brake
pad wear sensors.
Brake Fluid
The brake master cylinder reservoir is filled
with GM approved DOT 4 brake fluid as
indicated on the reservoir cap. See
Underhood Compartment Overview
0235 for
the location of the reservoir.
Checking Brake Fluid
With the vehicle in P (Park) on a level
surface, the brake fluid level should be
between the minimum and maximum marks
on the brake fluid reservoir.
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.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17272984) - 2024 - CRC - 2/20/23
266 Vehicle Care
.A fluid leak in the brake hydraulic system.
Have the brake 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 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
hydraulic system.
Caution
If too much brake fluid is added, the
brake fluid can spill and cause vehicle
damage, including damage to electrical
components and surfaces. Add brake fluid
only when work is done on the brake
hydraulic system.
When the brake fluid falls to a low level,
the brake warning light comes on. See Brake
System Warning Light 092. 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
0316.
What to Add
Use only GM approved DOT 4 brake fluid
from a clean, sealed container. See
Recommended Fluids and Lubricants 0320.
{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
Your vehicle may be equipped with a
standard 12-volt lead acid battery, 12-volt
lithium-ion battery, and/or a high voltage
battery.
See your dealer if the 12-volt lead acid
battery, 12-volt lithium-ion battery, or high
voltage battery need service.
12-Volt Lead Acid Battery
The original equipment battery is
maintenance free. Do not remove the cap
and do not add fluid.
Do not disconnect the 12-volt lead acid
battery during storage.
{Warning
WARNING: Battery posts, terminals and
related accessories can expose you to
chemicals including lead and lead
compounds, which are known to the
State of California to cause cancer and
birth defects or other reproductive harm.
Wash hands after handling. For more
information go to
www.P65Warnings.ca.gov.
See California Proposition 65 Warning 01.

310 Vehicle Care
cleaning, it is expected that brake dust and
road grime will darken the high performance
thermal coating over time.
{Warning
Altering, removing, or painting over the
white thermal coating on carbon fiber
wheels can cause the wheels to overheat
and become damaged. Damaged wheels
could cause a crash. To prevent property
damage, personal injury, and/or death,
do not change the coating on the carbon
fiber wheels.
Caution
Carbon fiber wheels 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
carbon fiber with soap and water after
exposure.
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,
vacuum pipes, electric vacuum pump
including bracket and vent hose, if equipped.
If equipped with Z51, inspect brake cooling
components. SeeTrack Events and
Competitive Driving 0160.
Steering, Suspension, and Chassis
Components
Visually inspect steering, suspension, and
chassis components for damaged, loose,
or missing parts or signs of wear at least
once a year.
Inspect power steering for proper hook-up,
binding, leaks, cracks, chafing, etc.
Visually check constant velocity joint boots
and axle seals for leaks.
Body Component Lubrication
Lubricate all key lock cylinders, hood hinges,
and liftgate hinges, unless the components
are plastic. Applying silicone grease on
weatherstrips with a clean cloth will make
them last longer, seal better, and not stick
or squeak.
Underbody Maintenance
At least twice a year, spring and fall, use
plain water to flush any corrosive materials
from the underbody. Take care to
thoroughly clean any areas where mud and
other debris can collect.
Do not directly power wash the transfer
case and/or front/rear axle output seals.
High pressure water can overcome the seals
and contaminate the fluid. Contaminated
fluid will decrease the life of the transfer
case and/or axles and should be replaced.
Body Damage
If the vehicle is damaged and requires sheet
metal repair or replacement, make sure the
body repair shop applies anti-corrosion
material to parts repaired or replaced to
restore corrosion protection.
