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 0173. 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 Performance Driving 0206.
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.

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).

Cluster Display
For more information on the display themes
of the Drive modes on the instrument
cluster, seeInstrument Cluster 081 >
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 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.

204 Driving and Operating
Engine Sound
Caution
Using a stealth engine sound setting
during spirited driving will cause the
exhaust system to overheat and damage
the variable exhaust valves. Do not use
this setting when auto-crossing or driving
on high speed tracks.
If available, engine sound settings change
when the variable exhaust valves open.
Steering (Assist Effort)
Adjusts from a lighter steering feel to
reduced assist for more steering feel.
Magnetic Ride Control
If equipped, this feature adjusts the shock
dampening firmness based on driving
conditions to improve comfort and
performance.
Drive Mode Customization
The vehicle is equipped to modify the
following vehicle settings base on vehicle
content. Through the infotainment home
screen, select Settings > Vehicle > “Drive
Mode Customization” to customize and
personalize My mode and/or Z-mode.
Engine Sound
Engine Sound adjusts the volume of engine
noise. Setting range from quietest to loudest
volume as you move from Stealth through
Track.
.Stealth, Tour, Sport, Track
Steering
This setting adjusts the effort required to
turn the steering wheel. The steering wheel
offers better feedback but requires more
effort as you move from Tour to Track.
.Tour, Sport, Track
Suspension
This setting adjusts the firmness of the
suspension in the vehicle. Suspension adjust
stiffness of the shocks and/or springs. The
ride is more comfortable at lower settings
and is stiffer at higher settings for better
control.
.Tour, Sport, Track Engine/Shift
This setting adjusts the throttle response,
gear shifting and engine performance. An
increased throttle response enhances the
acceleration feel as you move toward Track,
but with a comfort trade-off due to more
aggressive gear shifting.
.Weather, Tour, Sport, Track
Brake Feel
This setting adjusts the brake pedal
response. Settings range from a slower
response for more comfortable driving to
the quickest response for quicker
deceleration. Track allows for improved
pedal precision at higher decelerations for
high performance driving.

Performance Driving
If equipped, Competitive Driving mode,
Performance Traction Management (PTM),
and Launch Control are systems designed to
allow increased performance while
accelerating and/or cornering. This is
accomplished by regulating and optimizing
the engine, brakes, and suspension performance. These modes are for use at a
closed course race track and are not
intended for use on public roads. They will
not compensate for driver inexperience or
lack of familiarity with a race track.
Drivers who prefer to allow the system to
have more control of the engine, brakes,
and suspension are advised to turn on the
normal traction control and StabiliTrak/
Electronic Stability Control (ESC) systems on.
If equipped with E-Ray, there is a
Performance app on the infotainment screen
that shows the vehicle electric and engine
power/torque. See
“E-Ray Performance App”
later in this section for more information.
E-Ray Performance App
If equipped with E-Ray, to access the
Performance App, select the performance
app icon on the infotainment screen. The
landing screen of the Performance app is the
gauges page.

Dyno
While Driving
The Dyno page shows both electric and
engine power/torque in numeric and script
format. This shows the usage over time in
intervals of 15 or 30 seconds, or one or
two minutes. This is the same data as
shown on the gauges page but in a different
viewing format.
While in P (Park) When the car is shifted into P (Park), the
viewing cursor appears to allow the driver
to analyze the data in the viewing time
increment.
The Gauges and Dyno pages include the
Hybrid battery gauge indicating how much
battery charge is present.
Electric power/torque can be either positive
or negative. When electric power is being
provided the gauge shows positive values
and lights up orange. When electric power is
being stored, the gauge shows negative
values and lights up green.
Engine power is only positive and lights up
white.
Data
There are two available screens for the Data
page. Swipe the screen to the left to access
the second screen. See
Using the System
0 120.
The default screen displays the following
facts about the vehicle hybrid performance
and vehicle efficiency saved since the last
reset:
.Charge Gained is the accumulation of
brake and coast regen in units of energy.
.Charge Used is how much energy has
been used to enhance performance or
efficiency.
.Fuel Saved is the charge gained through
regen energy and converted to liters of
fuel saved.
The second screen displays the hybrid vitals,
such as the electric motor power and RPMs,
and hybrid battery and electric motor
temperature.
Settings
The setting menu allows the display to be
shown in preferred unit of metric or English
units.
To access the setting menu from any page

Launch Control (Sport and Track
Mode Only)
A Launch Control feature is available, within
Competitive Driving mode or PTM, on all
vehicles to allow the driver to achieve high
levels of vehicle acceleration in a straight
line. Launch Control is a form of TCS that
manages tire spin, and transmissions clutch,
while launching the vehicle. This feature is
intended for use during closed course race
events where consistent zero to
60 and quarter mile times are desirable.
Caution
The new vehicle break-in period should be
completed before using the launch
control feature, otherwise performance
will be limited and damage may occur to
the powertrain/engine. See New Vehicle
Break-In 0177. Launch Control is only available when the
following criteria are met:
.Competitive Driving mode or any of the
PTM modes are selected (if equipped). See
Driver Mode Control
0196.
.The steering wheel must be straight.
.The driver door must be closed.
.The vehicle must be in D (Drive) or
M (Manual mode).
.The parking brake must not be engaged.
Launching the Vehicle
.Ensure the vehicle is in Competitive
Driving mode or any of the PTM modes.
.The brake pedal must be firmly pressed
to the floor, equivalent to a panic brake
event.
.While maintaining the brake pedal, the
accelerator pedal is rapidly applied to
wide open throttle. If the vehicle rolls due
to wide open throttle or engine speed
does not exceed 3,000 Revolutions Per
Minute (RPM), release the throttle, press
the brake pedal more firmly, and reapply
the accelerator to wide open throttle.
.If the engine is cold, the vehicle may
be limited to 3000 rpm until
conditions are suitable for
acceleration.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17272984) - 2024 - CRC - 2/20/23
210 Driving and Operating
The Launch Control feature initially limits
engine speed as the driver rapidly applies
the accelerator pedal to wide open throttle.
Allow the engine RPMs to stabilize.
A smooth, quick release of the brake pedal,
while maintaining the fully pressed
accelerator pedal, will manage tire slip and
transmissions clutch. After the vehicle is
launched, the system continues in
Competitive Driving mode or PTM.
Custom Launch Control
If equipped, Custom Launch Control allows
the following parameters for Launch Control
to be modified:
.Launch RPM
.Slip Target (5%–15%)
Adjusting the Launch RPM will also change
the behavior of the transmission during the
start of the launch. The higher the Launch
RPM, the faster the clutch will be applied
resulting in greater acceleration. This
parameter can be used to match the launch
behavior to the available tire traction. If the
driving wheels spin excessively during the
launch, reduce the Launch RPM. To adjust the Launch RPM, all of these
conditions must be met:
.Competitive Driving mode or any of the
PTM modes are selected (if equipped). See
Driver Mode Control
0196.
.The steering wheel must be straight.
.The driver door must be closed.
.The vehicle must be in D (Drive) or
M (Manual mode).
.The parking brake must not be engaged.
1. Using the DIC buttons on the right side
of the steering wheel, navigate to the
performance menu. See Instrument
Cluster 081.
2. Select Launch Control > Custom.
3. Scroll down to Launch RPM.
4. Adjust the desired RPM: 3500, 4000, 4500, 4750, 5000
5. Set Slip Target to custom desired setting.

pedal to activate Launch Control.
7. Fully press the accelerator. Release thebrake pedal to launch the vehicle.
Limited-Slip Differential
The standard mechanical limited-slip
differential provides more traction on snow,
mud, ice, sand, or gravel. It works like a
standard axle most of the time, but when traction is low, this feature allows the drive
wheel with the most traction to move the
vehicle. See
Performance Driving 0206 and
Maintenance Schedule 0316.
Stingray, E-Ray, and Z06 Models Only
The Electrical Limited-Slip Differential (eLSD)
located on the rear axle is a hydraulically
actuated clutch system. It can infinitely vary
the clutch engagement between 0 and
2250 N*m (1659 lb-ft) of breakaway torque
between the rear wheels. When necessary it
responds from open to full engagement in
fractions of a second. Smaller clutch
adjustments happen even faster.
The eLSD:
.Uses the vehicle sensors and driver inputs
to determine the optimum amount of
clutch engagement for the conditions.
.Improves traction while cornering by
changing the engagement to achieve a
balance between directional control and
acceleration.
.Provides optimal engagement for
high-speed control and stability without
affecting precise steering and turn-in.
.Improves vehicle stability during spirited
driving and evasive maneuvers. It is fully
integrated with the Active Handling and
Performance Traction Management (PTM)
systems (if equipped).
There are unique calibrations based on the
Traction Control System (TCS) setting. eLSD
modes change automatically when the
traction control button is pressed. No unique
input from the driver is required.
.Mode 1 is the standard mode when the
vehicle is started. It provides a touring
calibration with an emphasis on vehicle
stability. Mode 1 is also used in PTM
Wet mode.
.Mode 2 is engaged when both TCS and
StabiliTrak are turned off. This calibration
provides more nimble corner turn-in, and
is biased for better traction out of
corners.
.Mode 3 is engaged when PTM is engaged
in Dry, Sport 1 & 2, and Race modes. This
is a nimble calibration with similar
functionality as eLSD Mode 2, however, it
is integrated to work with PTM.
.Mode 4 is engaged when TCS is selected
off, but StabiliTrak remains on. Vehicle
stability is still the priority, while allowing
for optimized traction out of corners.
