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
immediately after cranking has ended,
can overheat and damage the cranking
motor, and drain the battery. Wait at
least 15 seconds between each try, to let
the cranking motor cool down.
Stopping the Engine
Shift to P (Park) and press and hold ENGINE
START/STOP on the instrument panel, until
the engine shuts off. If the transmission is
not in P (Park), the engine shuts off and the
vehicle goes into the accessory mode. The

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).

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.

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

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.

Warning (Continued)
death, or vehicle damage. Before making
a lane change, always check mirrors,
glance over your shoulder, and use the
turn signals.
SBZA Detection Zones
The SBZA sensor covers a zone
approximately one lane over from both
sides of the vehicle, or approximately
3.5 m (11 ft). The height of the zone is
approximately between 0.5 m (1.5 ft) and
2 m (6 ft) off the ground. This zone starts at
approximately the middle of the vehicle and
goes back 5 m (16 ft).
How the System Works
The SBZA symbol lights up in the side
mirrors when the system detects a moving
vehicle in the next lane over that is in the
side blind zone. This indicates it may be
unsafe to change lanes. Before making a
lane change, check the SBZA display, check
mirrors, glance over your shoulder, and use
the turn signals.
Left Side Mirror DisplayRight Side Mirror Display
When the vehicle is started, both outside
mirror SBZA displays will briefly come on to
indicate the system is operating. When the
vehicle is in a forward gear, the left- or
right-side mirror display will light up if a
moving vehicle is detected in that blind
zone. If the turn signal is activated in the
same direction as a detected vehicle, this
display will flash as an extra warning not to
change lanes. SBZA can be disabled through vehicle
personalization. To view available settings
from the infotainment screen, touch
Settings > Vehicle > Collision/Detection
Systems. If SBZA is disabled by the driver,
the SBZA mirror displays will not light up.
When the System Does Not Seem to
Work Properly
SBZA displays may not come on when
passing a vehicle quickly, for a stopped
vehicle. SBZA may alert to objects attached
to the vehicle, such as a bicycle, or object
extending out to either side of the vehicle.
This is normal system operation; the vehicle
does not need service.
SBZA may not always alert the driver to
vehicles in the side blind zone, especially in
wet conditions. The system does not need
to be serviced. The system may light up due
to guardrails, signs, trees, shrubs, and other
non-moving objects. This is normal system
operation; the vehicle does not need service.
SBZA may not operate when the SBZA
sensors in the left or right corners of the
rear bumper are covered with mud, dirt,
snow, ice, or slush, or in heavy rainstorms.
