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.

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.

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.

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

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.
