Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17272984) - 2024 - CRC - 2/20/23
Driving and Operating 191
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)
.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 : 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 093. 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.
Drive Systems
All-Wheel Drive
If equipped with E-Ray, advanced electric
All-Wheel Drive (eAWD) delivers power to all
four wheels and adjusts automatically to the
driving conditions. The eAWD system
continuously varies the drive power to the

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17272984) - 2024 - CRC - 2/20/23
194 Driving and Operating
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. SeeDefensive Driving
0 157.
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.
Regenerative Braking
E-Ray models have a regenerative braking
system that activates when the brake pedal
is applied.
Regenerative braking captures some of the
energy from the moving vehicle and turns it
back into electrical energy. This energy is
then stored back into the high voltage
battery system, contributing to increased
energy efficiency.
The brake system uses regenerative braking,
conventional hydraulic braking, or a
combination of both as appropriate.
When the brake pedal is applied, a slight
sound may be heard. This is normal.
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 the vehicle
wheel brakes to assist the driver in keeping
the vehicle on the intended path.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17272984) - 2024 - CRC - 2/20/23
Driving and Operating 195
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. SeeCruise Control 0212.
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 0173 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.
If
=comes 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
=comes on and
stays on, the vehicle may need more time
to diagnose the problem. If the condition
persists, see your dealer.
Turning the Systems Off and On
The TCS/StabiliTrak/ESC button is on the
center console.
Caution
Do not repeatedly brake or accelerate
heavily when TCS is off. The vehicle
driveline could be damaged.

vehicle and ESC is in Competitive Mode,
Performance Traction Management (PTM)
mode, or if it has been turned off, the ESC
Off light will turn off when the vehicle
exceeds 160 km/h (100 mph), indicating that
StabiliTrak/ESC is fully enabled.
Hill Rollback Control
If the vehicle is in gear and inadvertently
rolls backwards, Hill Rollback Control helps
limit the rollback to a very low speed.
A noise may be heard while the vehicle
speed is actively being controlled. A Driver
Information Center (DIC) message displays
when active.
Driver Mode Control
Driver Mode Control (DMC) allows the driver
to adjust the overall driving experience to
better suit preference by selecting different
modes.
Drive mode availability and affected driver
systems are dependent upon vehicle trim
level, region, and optional features. Driver
modes may include: Weather, Tour, Sport,
and Track, along with two customizable
modes: My mode and Z-mode.
If equipped with E-Ray, there are two
additional EV drive modes and a Hybrid
Battery Charging (Charge+) feature. The two
EV drive modes, Shuttle and Stealth mode,
can be used without turning on the engine.
The Charge+ feature affects how each drive
mode operates.
Climate controls are disabled when in EV
drive modes, since the engine needs to be
running to generate heat or operate the air
conditioning system. The engine autostarts
when climate controls are turned on.
If equipped, the heated and cooled seats,
and the heated steering wheel are enabled
in EV drive modes.

E-Ray Only
Hybrid Battery Charging (Charge+)
The Charge+ feature is used to quickly
charge the high voltage battery to near
maximum State of Charge (SOC). This
feature is useful to prepare for maximum
effort at a racetrack or Stealth mode use. By
activating the Charge+ feature, it rapidly
increases the hybrid battery SOC status into the blue 100% full zone. See
Power Indicator
Gauge 087. When the Charge+ feature is
enabled, the battery SOC may still deplete
during aggressive driving.
The Charge+ feature can be used in
conjunction with any drive mode except
Stealth or Shuttle mode.
On a racetrack, using the Charge+ feature
optimizes the high voltage battery discharge
rate for sustaining continuous lapping or to
set your fastest lap. When the Charge+
feature is enabled, a strategic discharge rate
is activated, which is the best for continuous
lapping on the racetrack. When the Charge+
feature is off, a maximum discharge rate
occurs, which is best for setting the fastest
lap time. For additional details on vehicle
track preparation, see Chevrolet.com >
Corvette Experience > Guides > Track Prep
Guide.
Do not leave the Charge+ feature on longer
than needed since extra fuel may be
consumed due to aggressive charging.
Charge+ draws on engine power to help
recharge the battery quickly, rather than
charging efficiently through brake or coast
regen. When the high voltage battery is full,
no additional regen energy of any type can
be captured. When the Charge+ feature is turned off, the
high voltage propulsion system efficiently
uses battery energy to improve fuel
economy or performance. This allows room
in the high voltage battery for the next
regen charging opportunity. The high
voltage battery automatically seeks its
nominal SOC in the white zone of the
Hybrid Battery Gauge, between 50-80%. The
SOC status is displayed in the HYBRID
BATTERY info tile, and is shown in the blue
Hybrid Battery state. See
“Info Tiles”in
Instrument Cluster 081.
The Charge+ feature is only effective when
the car is being driven. Optimal high voltage
battery charging occurs when the vehicle
speed exceeds 56 km/h (35 mph).

200 Driving and Operating
Turning On or Off Charge+
Press the Charge+ button on the drive side
of the center console. When the Charge+
feature is active, the hybrid battery charging
light displays on the DIC. SeeHybrid Battery
Charging Light (Charge+) 087. Also, a small
pop-up window will also appear showing the
exact SOC and electric power input/output.
The Hybrid Battery Gauge shows the
increasing SOC filling into the blue zone. See
Power Indicator Gauge 087.
EV Drive Mode Attributes
Stealth Mode : Use to silently exit your
residence before the engine turns on for
maximum performance capability. The
typical range in Stealth mode is about three to four miles depending on the starting SOC,
vehicle speed, and other driving conditions.
The Stealth Drive Mode Capability Gauge on
the instrument cluster informs the driver of
when the engine will start, see
Stealth Drive
Mode Capability Gauge 086.
Stealth mode automatically deactivates if
the following occurs:
.The vehicle speed exceeds 72 km/h
(45 mph).
.The outside temperature is lower than
10°C (50°F).
.The high voltage battery SOC is lower
than 21%.
.Quickly depressing the accelerator pedal.
.Depressing the accelerator pedal beyond
one-third of the way.
.Turning on the climate controls. See Dual
Automatic Climate Control System 0150.
If one of the conditions occur, an indicator
on the Driver Information Center (DIC)
displays explaining Stealth mode was
automatically deactivated.
When Stealth mode is deactivated, the
vehicle will transition into Tour mode. Stealth mode can only be activated one
time per ON/OFF cycle. Once the engine
auto-starts while in Stealth mode, the only
way to re-enter Stealth mode is to put the
vehicle in P (Park), turn the vehicle off and
repeat the steps above in the
“E-Ray–EV
Drive Mode Activation” section.
Once the engine starts, the propulsion
system transitions from EV propulsion to
engine power. A message will display on the
EV selection menu to indicate how long the
engine power transition will take. This
transition may take two to four seconds
depending on the engine temperature.
The electric power indicator gauge will
indicate a transition from EV propulsion to
engine propulsion. The instrument cluster
will show two or three phases of the
transition (red, yellow, green) and then
display the engine tachometer when the
transition is complete.
If Stealth Mode was used in the beginning
of a drive cycle, the Stop/Start System will
be disabled. The vehicle must be turned off
and restarted normally to enable the Stop/
Start System. See Stop/Start System 0180.

{Warning
When exiting Stealth mode, allow
sufficient time for the vehicle to
automatically start the engine and
develop full system propulsion power
before merging into traffic. Attempting to
merge into traffic before the engine has
reached full power could cause a crash
resulting in vehicle damage, personal
injury, or death. It is best to exit Stealth
mode first and allow the engine to reach
full capacity before engaging in traffic.
Shuttle Mode : Use to propel the vehicle
using only electric power. Shuttle mode is
not intended for public roads. The typical
range in Shuttle mode is about four to
five miles depending on the starting SOC,
vehicle speed, terrain, and other driving
conditions. While the vehicle is in Shuttle
mode, the instrument cluster only displays
the vehicle speed, battery gauge, and a
electric power indicator gauge. The infotainment screen will only show the
date and time. If equipped, the HUD system
will not be functional.
Shuttle mode automatically deactivates if
the following occurs:
.The vehicle speed exceeds 24 km/h
(15 mph).
.The outside temperature is lower than
–
10°C (14°F).
.The high voltage battery SOC is 0%.
To deactivate Shuttle mode, put the vehicle
in P (Park) and turn off the vehicle. Then,
start the vehicle normally.
Shuttle mode will automatically start to
reduce propulsion power as the SOC reaches
0%. The message Start Engine to Charge
Battery will display on the instrument
cluster when the SOC reaches 5%.
If the engine is not started, propulsion
power reduces automatically and the vehicle
comes to a stop. The only way to charge your battery is to
start and run the vehicle from Normal mode.
See
“Normal Mode” later on in this section.
Do not store the hybrid battery with a low
SOC for an extended period of time. It is
best to store the battery in the white
eAWD zone.
Normal Mode : Use to have a normal
engine start when going through the EV
drive mode selection process.
Starting and running the vehicle from
Normal mode allows the engine and front
electric motor to regenerate power to
charge the hybrid battery.

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 093.
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
anticipating 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)
If equipped with Active Fuel Management
(AFM), the engine uses driver demand to
deactivate cylinders to improve fuel
performance. When accelerating, V8 mode is
prevalent. For lighter throttle applications,
the system may disable cylinders to run in
4-cylinder mode to save fuel.
Active Fuel Management is a preset of
Powertrain and cannot be modified or
changed independently.
