198 Driving and Operating
To shift out of D (Drive):1. Bring the vehicle to a complete stop.
2. Shift to the desired gear.
Downshifting the transmission in slippery
road conditions could result in skidding. See
“Skidding” underLoss of Control 0172.
The transmission can be shifted like a
manual transmission using the paddle shift
controls while in D (Drive). See Manual
Mode 0198.
Caution
Spinning the tires or holding the vehicle
in one place on a hill using only the
accelerator pedal may damage the
transmission. The repair will not be
covered by the vehicle warranty. If the
vehicle is stuck, do not spin the tires.
When stopping on a hill, use the brakes
to hold the vehicle in place.
Manual Mode
Manual Paddle Shift
With the transmission in D (Drive), press the
M (Manual Mode) switch on the center
console to enter Manual Mode. Use the
paddles on the steering wheel to manually
upshift or downshift the transmission.
The right + (plus) paddle upshifts, and the
left −(minus) paddle downshifts. When using the Manual Paddle Shift
system, the current gear will be displayed in
the instrument cluster or the Head-Up
Display (HUD), if equipped. See
Head-Up
Display (HUD) 095.
When accelerating the vehicle from a stop in
snowy and icy conditions, shifting to
2 (Second) gear, when available, will allow
the vehicle to gain more traction.
The Manual Paddle Shift system can be
deactivated by pulling the D (Drive) switch
on the center console.
With the transmission in D (Drive), pull the
right + paddle or the left −paddle to place
the transmission in Temporary Manual
Paddle Shift mode.

Driving and Operating 203
.Vehicle is in R (Reverse)
.Paddles are released separately
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.
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 if the
Traction Control System (TCS) is turned off
while performing a Rapid Exit. Rapid Exit
launch occurs when all of the following
conditions are met:
.Vehicle speed is below 10 km/h (6 mph)
.Vehicle is in D (Drive) or
M (Manual Mode)
.Both paddles 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).
Manual Launch (Z06 model only) :
While
the vehicle is in Double Paddle Declutch,
Manual Launch can be activated to gain
more precise control over the engine speed
to prepare for a Standard or Rapid Exit. To
activate this feature, first enter Double
Paddle Declutch, then release and repull
either the + paddle or −paddle while
keeping the opposite paddle held. The
Performance Transmission Active Light will
illuminate in the gauge cluster to indicate
that Manual Launch has been activated. See
Performance Transmission Active 089.
When Manual Launch is active, the engine
will respond differently when the accelerator
pedal is pressed compared to normal Double
Paddle Declutch. The accelerator pedal must
be pressed further to increase the engine
rpm and a lower engine rpm limit will be
applied. This feature also provides faster
engine response during a Rapid Exit if any
of the Performance Traction Management
(PTM) modes or Electronic Stability Control
(ESC) Off has been selected. To exit Manual Launch, release both the + paddle and
−
paddle. The vehicle will also exit Double
Paddle Declutch and the engine will
reconnect to the wheels. A Standard Exit or
Rapid Exit will be performed based on the
same conditions listed previously.
{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 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
turned off. Noise may be heard during this
time. If the brake pedal is pressed during

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16287457) - 2023 - CRC - 3/10/22
204 Driving and Operating
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 088.
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
The Electric Parking Brake (EPB) can always
be applied, even if the vehicle is off. In case
of insufficient electrical power, the EPB cannot be applied or released. To prevent
draining the battery, avoid unnecessary
repeated cycles of the EPB.
The system has a red parking brake status
light and an amber service parking brake
warning light. See
Electric Parking Brake
Light 088 and
Service Electric Parking Brake Light 088.
There are also parking brake-related Driver
Information Center (DIC) messages.
Before leaving the vehicle, check the red
parking brake status light 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 red parking brake status light will flash
and then stay on once the EPB is fully
applied. If the red parking brake status light
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,

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16287457) - 2023 - CRC - 3/10/22
Driving and Operating 205
have the vehicle serviced. Do not drive the
vehicle if the red parking brake status light
is flashing. See your dealer.
If the amber service parking brake warning
light is on, press the EPB switch. Continue to
hold the switch until the red parking brake
status light remains on. If the amber service
parking brake warning light is 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, or at the request of other
safety functions that utilize the EPB.
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 accessory mode. 2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the red parking
brake status light is off.
If the amber service parking brake warning
light is on, release the EPB by pressing and
holding the EPB switch. Continue to hold the
switch until the red parking brake status
light 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.
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 Driving
0 170.
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

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16287457) - 2023 - CRC - 3/10/22
206 Driving and Operating
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.
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 thespinning 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 the vehicle
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 0219.
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 0185 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
=comes 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.

Options > Display themes.
Throttle Progression
Adjusts throttle sensitivity by selecting how
quickly or slowly the throttle reacts to
input.
Throttle Progression is a preset of
Powertrain and cannot be modified or
changed independently.
Transmission Shift Operation
Basic:
.Transmission upshifts and downshifts are
selected based on vehicle speed and
accelerator position to optimize comfort
and fuel economy during mild driving
conditions.
Driver Influenced Gear Selection:
.Aggressive driving will influence both the
upshift and downshift points in all modes.
When engaged, the Performance
Transmission Active light displays. See
Performance Transmission Active 089. When Performance Transmission is
activated from a standstill, by selecting
PTM Race 1 or Race 2, the transmission
shift map is in the most aggressive state
where upshifts are only achieved at high
revolutions per minute (rpm), downshifts
happen early, and the lowest gear is
selected for cornering. Transmission
behavior will transition to a level
appropriate to the current driving
behavior after a short period of time.
If PTM Race 1 or Race 2 are not selected,
the Performance Transmission Active
behavior still activates automatically after
a sustained period of performance driving
is detected. See
“Performance Traction
Management (PTM)” later on in this
section.
.Criteria which have influence are: driving
mode, accelerator, brakes, lateral, and
longitudinal loading.
.Changes in gear selection behavior due to
aggressive driving can include:
‐ Downshifting early with higher rpm’s
during aggressive braking (i.e. entering
a corner)
‐ Altering upshifts while experiencing
lateral acceleration ‐
Not upshifting when the accelerator is
released to avoid unnecessary shifts if
the accelerator is re-applied
‐ Recognizing sporty driving and
anticipate upcoming corners with the
appropriate gear selection entering and
exiting
.Driver Modes
‐Driver influenced changes are effective
in all driving modes, however the
aggressiveness of the transmission
response will increase between Tour,
Sport, and Track Modes respectively.
Active Fuel Management (Engine Cylinder
Shuts Off)
.Normal with Dual Clutch Transmission:
The engine uses 8-cylinder mode when
accelerating, but changes to 4-cylinder
mode when coasting.
Active Fuel Management is a preset of
Powertrain and cannot be modified or
changed independently.
