Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12470550) - 2020 - CRC - 4/23/20
152 Driving and Operating
Caution
Some high octane fuels contain
additives and compounds that
may damage the vehicle and void
the vehicle warranty. See
Prohibited Fuels 0 205.
Dual Clutch Transmission
Fluid
The transmission fluid and external
filter should be changed after every
24 hours of track usage. If prompted
by the transmission fluid life monitor
that remaining fluid life is low, the
fluid and external filter should be
changed as soon as possible.
Add an additional 2 L (2 qt) of DCT
transmission fluid prior to track
usage. It is not required to remove
the additional 2 L (2 qt) of DCT fluid.
Any transmission level set or
change should be performed at your
dealer.
Brakes
Brake Fluid
Replace existing brake fluid with a
qualified high performance brake
fluid from a sealed container. Brake
fluid with a dry boiling point >310 °C
(590 °F) is qualified. If high
performance brake fluid is used,
replace it with GM approved brake
fluid before driving on public roads.
If high performance brake fluid is in
the vehicle and the age of the brake
fluid is over a month old or
unknown, replace the brake fluid
before track events and competitive
driving. Do not use silicone or
DOT-5 brake fluids.
Check the fluid level before each
competitive driving event.
Brake Fade Warning Assist
The Brake Fade Warning Assist
system monitors the performance of
the brake system. If the system
detects brake fade, or if the brake
fluid is near the boiling point, the
driver will be alerted.
The Brake Fade Warning Assist
system is designed for use with the
factory-installed brake pads or
GM-approved replacement pads.
If the brake pads on the vehicle
need to be replaced, use
GM-approved brake pads. If this is
not done, the brake fade warning
system may not function properly.
Stage 1 : The Driver Information
Center (DIC) displays a “Reduce
Braking to Avoid Overheating”
message and brake pedal effort and
travel is increased. When the
message displays, the driver should
decrease brake pedal pressure.
Stage 2 : The Driver Information
Center (DIC) displays a “Brakes
Overheated Service Now” message
that the brake fluid temperature is
excessive and is about to boil. The
system increases brake pedal effort
and travel, and will also limit vehicle
speed. The driver should
immediately start a cool down lap if
on the track. If this message
displays, take the vehicle to be
serviced at your dealer.
