Double Paddle Declutch allows the
vehicle to temporarily disconnect
the engine from the wheels
–similar
to N (Neutral). This feature is
activated by pulling and holding
both the + paddle and −paddle at
the same time while the vehicle is in
R (Reverse), D (Drive), or M
(Manual Mode). The vehicle will
remain in this condition until both
the + paddle and −paddle are
released.
The R, D, or M indicator on the
center shift console will flash red to
indicate that the vehicle is in Double
Paddle Declutch. In addition, the
current gear state indicator in the
DIC may dim to gray to indicate that
the vehicle is in Double Paddle
Declutch.
To exit Double Paddle Declutch,
release both the + paddle and −
paddle. The engine will reconnect to
the wheels and the shift indicator
will stop flashing. There are two
Double Paddle Declutch exit styles:

12470550) - 2020 - CRC - 4/23/20
178 Driving and Operating
Rapid Exit :This is intended for
use at a closed course race track
and not on public roads. Engine
power is reapplied to the wheels
quickly to support spirited driving.
The rate of launch is dependent on
how much the accelerator pedal is
pressed when the paddles are
released: The further the accelerator
pedal is pressed, the greater the
rate of launch. Tire spin may occur
with the accelerator pedal pressed
and the Traction Control System
(TCS) turned off.
This launch occurs when both of
these conditions are met:
. Vehicle speed is below
10 km/h (6 mph).
. Both the + paddle and −paddle
are released at the same time.
With the accelerator fully pressed
and the engine at the rev limiter,
peak performance only occurs if the
paddles are released within a short
period of time after reaching the rev
limit (i.e., a few seconds). Standard Exit :
Engine power is
reapplied to the wheels gently to
support normal vehicle operation on
public roads.
This occurs when paddles are
released under any of the these
conditions:
. Vehicle speed is above
10 km/h (6 mph).
. The vehicle is in R (Reverse).
. The + paddle and −paddle are
not released at the same time.
If the vehicle was in Temporary
Manual Paddle Shift mode before
entering Double Paddle Declutch,
the vehicle will return to D (Drive)
with automatic shifting upon exiting
Double Paddle Declutch.
{Warning
When exiting Double Paddle
Declutch, the vehicle may move
rapidly. You could lose control
and cause a crash with nearby
people or objects. Be ready to (Continued)
Warning (Continued)
release the accelerator pedal or
apply the brakes immediately if
the vehicle moves too quickly. Do
not use the Double Paddle
Declutch when people or objects
are near.

Brakes
Electric Brake Boost
Vehicles equipped with electric
brake boost have hydraulic brake
circuits that are electronically
controlled when the brake pedal is
applied during normal operation.
The system performs routine tests
and turns off within a few minutes
after the vehicle is shutdown. Noise
may be heard during this time. If the
brake pedal is pressed during the
tests or when the electric brake
boost system is off, a noticeable
change in pedal force and travel
may be felt. This is normal.
Antilock Brake
System (ABS)
The Antilock Brake System (ABS)
helps prevent a braking skid and
maintain steering while
braking hard.
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
0 105.
ABS does not change the time
needed to get a foot on the brake
pedal and does not always
decrease stopping distance. If you
get too close to the vehicle ahead,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room ahead to stop,
even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly.
Hearing and feeling ABS operate is
normal.
Braking in Emergencies
ABS allows steering and braking at
the same time. In many
emergencies, steering can help
even more than braking.
Electric Parking Brake
If equipped, the Electric Parking
Brake (EPB) can always be
activated, even if the ignition is off.
To prevent draining the battery,
avoid repeated cycles of the EPB
system when the engine is not
running.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12470550) - 2020 - CRC - 4/23/20
180 Driving and Operating
The system has aYElectric
Parking Brake light, and a
8Service
Parking Brake light. See Electric
Parking Brake Light 0104 and
Service Electric Parking Brake Light
0 105.
Before leaving the vehicle, check for
the
Ylight to ensure that the
parking brake is applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Press the EPB switch momentarily.
The
Ylight will flash and then stay
on once the EPB is fully applied.
If the
Ylight flashes continuously,
then the EPB is only partially
applied or there is a problem with
the EPB. A DIC message will
display. Release the EPB and try to
apply it again. If the light does not
come on, or keeps flashing, have the vehicle serviced. Do not drive
the vehicle if the
Ylight is flashing.
See your dealer.
If the
8light is on, press the EPB
switch and hold it. Continue to hold
the switch until the
Ylight remains
on. If the
8light remains on, see
your dealer.
If the EPB is applied while the
vehicle is moving, the vehicle will
decelerate as long as the switch is
pressed. If the switch is pressed
until the vehicle comes to a stop,
the EPB will remain applied.
The vehicle may automatically apply
the EPB in some situations when
the vehicle is not moving. This is
normal, and is done to periodically
check the correct operation of the
EPB system.
If the EPB fails to apply, block the
rear wheels to prevent vehicle
movement.
EPB Release
To release the EPB: 1. Turn the ignition on or to ACC/
ACCESSORY.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the
Y
light is off.
If the
8light is on, release the EPB
by pressing and holding the EPB
switch. Continue to hold the switch
until the
Ylight is off. If either light
stays on after release is attempted,
see your dealer.
Caution
Driving with the parking brake on
can overheat the brake system
and cause premature wear or
damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.

Driving and Operating 181
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to
drive away. Avoid rapid acceleration
when the EPB is applied, to
preserve parking brake lining life.
Brake Assist
Brake Assist detects rapid brake
pedal applications due to
emergency braking situations and
provides additional braking to
activate the Antilock Brake System
(ABS) if the brake pedal is not
pushed hard enough to activate
ABS normally. Minor noise, brake
pedal pulsation, and/or pedal
movement during this time may
occur. Continue to apply the brake
pedal as the driving situation
dictates. Brake Assist disengages
when the brake pedal is released.
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA feature.
HSA does not replace the need to
pay attention and drive safely.
You may not hear or feel alerts or
warnings provided by this system.
Failure to use proper care when
driving may result in injury, death,
or vehicle damage. See
Defensive Driving0147.
When the vehicle is stopped on a
grade, Hill Start Assist (HSA)
prevents the vehicle from rolling in
an unintended direction during the
transition from brake pedal release
to accelerator pedal apply. The
brakes release when the accelerator
pedal is applied. If the accelerator
pedal is not applied within a few
minutes, the Electric Parking Brake
will apply. The brakes may also
release under other conditions. Do
not rely on HSA to hold the vehicle. HSA is available when the vehicle is
facing uphill in a forward gear,
or when facing downhill in
R (Reverse). The vehicle must
come to a complete stop on a grade
for HSA to activate.

182 Driving and Operating
Ride Control Systems
Traction Control/
Electronic Stability
Control
The vehicle has a Traction Control
System (TCS) and a StabiliTrak/
Electronic Stability Control (ESC)
system. These systems help limit
wheel spin and assist the driver in
maintaining control, especially on
slippery road conditions.
TCS activates if it senses that the
rear wheels are spinning too much
or are beginning to lose traction.
When this happens, TCS applies
the brakes to the spinning wheel
and reduces engine power (by
closing the throttle and managing
engine spark) to limit wheel spin.
StabiliTrak/ESC activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak/ESC selectively applies
braking pressure to any one of thevehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used when
TCS begins to limit wheel spin, the
cruise control will automatically
disengage. Cruise control may be
reengaged when road conditions
allow. See
Cruise Control 0196.
If the driver disables TCS, cruise
control will disengage. Cruise
control will also be disabled if
Performance Traction Management
(PTM) is selected, or if StabiliTrak is
turned off.
Both systems come on
automatically when the vehicle is
started and begins to move. The
systems may be heard or felt while
they are operating or while
performing diagnostic checks. This
is normal and does not mean there
is a problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow. See
If the Vehicle Is Stuck 0159
and “Turning the Systems Off and
On” later in this section.
The indicator light for both systems
is in the instrument cluster. This
light will:
.
Flash when TCS is limiting
wheel spin
. Flash when StabiliTrak/ESC is
activated
. Flash when ABS is active
. Turn on and stay on when either
system is not working
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC), and
dcomes on and stays on to
indicate that the system is inactive
and is not assisting the driver in

maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly.
If
dcomes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.
Drive the vehicle. If
dcomes on and
stays on, the vehicle may need
more time to diagnose the problem.
If the condition persists, see your
dealer.
