192 Driving and Operating
Cell phone chargers can interfere with the
operation of the Keyless Access system.
Battery chargers should not be plugged in
when starting or turning off the engine.1. Press the brake pedal, then press ENGINE START/STOP on the instrument panel.
If there is no remote key in the vehicle
or if there is something causing
interference with it, the Driver
Information Center (DIC) will display a
message.
2. When the engine begins cranking, let go of the button and the engine cranks
automatically until it starts.
If the battery in the remote key is weak,
the DIC will display a message. The
vehicle can still be driven.
See “Starting the Vehicle with a Low
Remote Key Battery” underRemote Key
Operation 07. If the remote key battery
is dead, insert it into the cupholder
remote key pocket to enable engine
starting.
3. Do not race the engine immediately after starting it. Operate the engine and
transmission gently until the oil warms
up and lubricates all moving parts. 4. If the engine does not start and no DIC
message is displayed, wait 15 seconds
before trying again to let the cranking
motor cool down.
If the engine does not start after five to
10 seconds, especially in very cold
weather (below −18 °C or 0 °F), it could
be flooded with too much gasoline. Try
pushing the accelerator pedal all the way
to the floor while cranking for up to
15 seconds maximum. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down. When
the engine starts, let go of the
accelerator. If the vehicle starts briefly
but then stops again, repeat these steps.
This clears the extra gasoline from the
engine.
Caution
Cranking the engine for long periods of
time, by pressing ENGINE START/STOP

194 Driving and Operating
Parking over Things That Burn
{Warning
Things that can burn could touch hot
exhaust parts under the vehicle and
ignite. Do not park over papers, leaves,
dry grass, or other things that can burn.
Active Fuel Management
This vehicle's engine may be equipped with
Active Fuel Management, which allows the
engine to operate on either all or half of its
cylinders, depending on the driving
conditions.
When less power is required, such as
cruising at a constant vehicle speed, the
system will operate in the half cylinder
mode, allowing the vehicle to achieve better
fuel economy. When greater power
demands are required, such as accelerating
from a stop, passing, or merging onto a
highway, the system will maintain
full-cylinder operation.If the vehicle has an Active Fuel
Management indicator, see Driver
Information Center (DIC) for more
information on using this display.
Extended Parking
It is best not to park with the vehicle
running. If the vehicle is left running, be
sure it will not move and there is adequate
ventilation.
See
Shifting Into Park 0193 and
Engine Exhaust 0194.
If the vehicle is left parked and running with
the remote key outside the vehicle, it will
continue to run for up to 15 minutes.
If the vehicle is left parked and running with
the remote key inside the vehicle, it will
continue to run for up to 30 minutes.
The vehicle could turn off sooner if it is
parked on a hill, due to lack of
available fuel.
The timer will reset if the vehicle is taken
out of P (Park) while it is running.
Engine Exhaust
{
Warning
Engine exhaust contains carbon monoxide
(CO), which cannot be seen or smelled.
Exposure to CO can cause
unconsciousness and even death.
Exhaust may enter the vehicle if:
.The vehicle idles in areas with poor
ventilation (parking garages, tunnels,
deep snow that may block underbody
airflow or tail pipes).
.The exhaust smells or sounds strange
or different.
.The exhaust system leaks due to
corrosion or damage.
.The vehicle exhaust system has been
modified, damaged, or improperly
repaired.
.There are holes or openings in the
vehicle body from damage or
aftermarket modifications that are not
completely sealed. (Continued)

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.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16287457) - 2023 - CRC - 3/10/22
Driving and Operating 199
To exit Temporary Manual Paddle Shift
mode do one of the following:
.Hold the + paddle for more than
one second.
.Drive at a steady speed without manual
shifts or aggressive cornering for several
seconds.
.Lower vehicle speed to 6 km/h (4 mph)
or less.
While the Manual Paddle Shift system is
active, the transmission will automatically
downshift through the gears as the vehicle
slows. The transmission will select 1 (First)
gear as the vehicle stops. From a stop, the
vehicle will start from and hold 1 (First) gear
unless Manual Paddle Shifts are used to
shift into a different gear, or D (Drive) is
selected. To cause the transmission to downshift to
the lowest gear possible for the vehicle
speed, in Manual Paddle Shift or Temporary
Manual Paddle Shift mode:
.Pull and briefly hold the
−paddle. If the
paddle continues to be held as the vehicle
slows, downshifts will continue as vehicle
speed allows.
The Manual Paddle Shift system will not
upshift or downshift if vehicle speed is too
fast or too slow, and will not start from any
gear other than 1 (First) gear.
If upshifting does not occur when necessary
in Manual Paddle Shift mode, vehicle speed
is limited to protect the engine. When in
Temporary Manual Paddle Shift mode, the
transmission will automatically upshift if the
accelerator pedal is pressed all the way to
the floor. Manual Paddle Shift can be used with cruise
control. See
Cruise Control 0219.
At maximum engine speed (rpm), auto-shifts
will occur after a specified time period to
protect the engine.
The vehicle speeds required for Manual
Paddle Shift upshifts depend on several
vehicle inputs, which will vary the allowed
upshift speed by a few km/h (mph).
To prevent damage to the powertrain,
Manual Paddle downshifts cannot be
performed above certain speeds.
The vehicle speeds for allowed Manual
Paddle shifts can vary by vehicle model or
optional equipment; such as the Stingray Z51
with Electronic Limited-Slip Differential
(eLSD) differs from non-Z51 with Mechanical
Limited-Slip Differential (mLSD).

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 Driver
Information Center (DIC) may change to
flashing blue 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:
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:
.Accelerator pedal is fully released
.Vehicle speed is above 10 km/h (6 mph)

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16287457) - 2023 - CRC - 3/10/22
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

Mode Description
uWeather :Used for slippery surfaces to
help control wheel speed. This can
compromise the acceleration on dry asphalt.
This feature is not intended for use when
the vehicle is stuck in sand, mud, ice, snow,
or gravel. If the vehicle becomes stuck, see If
the Vehicle Is Stuck 0185. See “Driver Mode
Attributes,” later in this section.
sTour :Use for normal city and highway
driving to provide a smooth, soft ride. This
setting provides a balanced setting between
comfort and handling. This is the standard
mode. See “Driver Mode Attributes,” later in
this section.
rSport : Use when road conditions or
personal preference demand a more
controlled response. When this mode is
selected, the vehicle will immediately
downshift. The steering will change to
provide more precise control. If the vehicle
has Magnetic Ride Control, the suspension
will change to provide better cornering
performance. Competitive Mode can be accessed through
this mode. See
Competitive Driving Mode
0 215.
tTrack : Use for closed race tracks. Use
when maximum vehicle handling is desired.
When in Track Mode, the dual clutch
transmission and steering will adjust to
track settings. In this mode the vehicle also
monitors driving behaviors and
automatically enables Performance Shift
features when spirited driving is detected.
These features maintain lower transmission
gears to increase available engine braking
and improve acceleration response. The
vehicle will exit this feature and return to
normal operation after a short time when
spirited driving is no longer detected.
If equipped, this mode also modifies real
time damping, exhaust valve tuning, engine
sound, brake pedal feel, Electronic Stability
Control (ESC) performance and Traction
Control System (TCS) performance.
Performance Traction Management (PTM)
can be accessed through this mode. See
“Performance Traction Management,” later
in this section.
qMy Mode : Use to personalize everyday
driving. This mode allows the driver to
configure the driver systems to their driving
preferences. This mode modifies the
suspension, steering, brake feel, and engine
sound. My Mode will remain active across
ignition cycles.

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.
