DUAL CLUTCH TRANSMISSION
The Dual Clutch Transmission provides an extremely connected feel with very fast shift times for maximum performance. The transmission is electronically contro\
lled using the shift switches located on the center console. The selected gear position\
illuminates in red on the shift switch.
Park – Press the P button to shift to Park.
Reverse – Pull the R switch to shift to Reverse.
Neutral – Press and hold the N button until the indicator is red to shift to Neutral.
Drive – Pull the D switch to shift to Drive.
MANUAL MODE
The Dual Clutch Transmission can be shift-ed manually using the paddles behind the steering wheel.
With the transmission in Drive, press the Manual Mode (M) button to shift manually. Pull the left (–) steering wheel paddle to downshift and the right (+) steering wheel paddle to upshift. The current gear is displayed on the instrument cluster and HUDF. The transmission will hold the current gear until a change is requested. Pull the Drive (D) switch to return to Drive.
To engage temporary manual paddle shifts, pull either the left (–) \
or right (+) steering wheel paddle with the transmission in Drive (D). The transmission will\
return to auto-matic shifting after approximately 6 seconds of cruising at steady speed\
s and without any manual shifts or by pulling and holding the right paddle for more th\
an 1 second. Automatic shifting also will return when the vehicle stops.
To downshift to the lowest gear possible for the current vehicle speed, \
pull and briefly hold the left (–) steering wheel paddle.
If vehicle speed is too fast or too slow for the requested gear, the shi\
ft will not occur.
DOUBLE PADDLE DECLUTCH
Double Paddle Declutch allows the vehicle to temporarily disconnect the \
engine from the wheels, similar to shifting to Neutral.
Pull and hold both the left (–) and right (+) steering wheel padd\
les at the same time to activate Double Paddle Declutch. The gear position indicator on the cent\
er console will flash red and the gear position indicator on the instrument cluster wi\
ll turn gray. Release both paddles to exit Double Paddle Declutch.

The Driver Mode Control system can provide enhanced performance for diff\
erent driving conditions by automatically adjusting the steering, throttle progression\
, shift mode, braking response, suspensionF, traction control, engine sound, instrument cluster theme, and other calibrations (if equipped) in real time. The modes ar\
e displayed on the Driver Information Center.
Rotate the Driver Mode Control knob on the center console to select the \
desired mode:
MyMode – Allows the engine sound, steer-ing, suspensionF, and braking response to be customized to your preference in everyday driving.
Weather – Use during slippery conditions to help control wheel speed.
Tour – Use in normal driving for balanced comfort and handling.
Sport – Use where road conditions or personal preference dictate a more performance-oriented response.
Track – Use when maximum vehicle
performance is desired. Track mode is for closed racetracks.
Z-Mode – Press the Z-Mode button on the steering wheel to activate custom-ized engine sound, steering, suspensionF,
powertrain, and braking response settings for maximum handling.
The mode features vary. Not all vehicles have all features. Allow a few seconds for the changes to be activated before the current mode is displayed.
DRIVER MODE CUSTOMIZATION
The MyMode and Z-Mode settings can be customized in the Settings menu on the infotainment screen.
Go to Settings > Vehicle > MyMode or Z-Mode to change the engine sound, steering, suspensionF, powertrain, and brake response settings.

HIGH-PERFORMANCE DRIVING FEATURES
PTM MODESF
PTM 1 – WET is for wet or damp conditions. ESC is on and engine power is reduced ba\
sed on conditions.
PTM 2 – DRY is for dry conditions. ESC is on and engine power is slightly reduced.
PTM 3 – SPORT 1 is for dry conditions. ESC is on and additional engine power is availabl\
e.
PTM 4 – SPORT 2 is for dry conditions. ESC is off and engine power is the same as PTM 3\
.
PTM 5 – RACE is for dry conditions. ESC is off and additional engine power is availa\
ble for maximum cornering speed.
LAUNCH CONTROL
Launch Control, available when Competitive Driving Mode or PTM is select\
ed, is a form of traction control that manages tire spin while launching the vehicle to h\
elp achieve high levels of acceleration in a straight line.
With the vehicle not moving and the wheels pointed straight, press the b\
rake pedal very firmly to the floor, rapidly press the accelerator pedal to wid\
e open throttle, and then release the brake pedal while fully pressing the accelerator pedal.\
The system initially limits engine speed and manages wheel slip.
See Driving and Operating in your Owner’s Manual.
DRY SUMP OIL LEVEL INSPECTION
To check the oil level, run the engine to operating temperature. With th\
e engine run-ning at idle, check the oil level on the dipstick located on top of the \
external oil tank.
Note: Overfilling the oil tank may lead to an oil leak or engine damage.
The oil and filter should be changed when indicated by the engine oil life system. A Change Engine Oil Soon message will be displayed on the Driver Information Center. Oil and filter change intervals are based on a combination of factors, including engine revolutions, temperature and miles driven. Reset the engine oil life system every time the oil is changed.
ENGINE COMPARTMENT ACCESS (CONVERTIBLE MODEL)F
To raise the tonneau cover to the service position:
1. With the vehicle in Park, press and release the Lock button on the Remote Keyless Entry (RKE) transmitter.
2. Immediately press and hold the button on the RKE transmitter.
SERVICE COVERS
The Corvette has several service covers underhood and in the engine comp\
artment that must be opened in order to access certain components. Make sure that all\
covers are properly secured after performing any service checks.

HIGH-PERFORMANCE DRIVING FEATURES
TRANSMISSION FLUID
The Dual Clutch Transmission fluid and filter should be changed when\
indicated by the transmission fluid life system. A Change Transmission Fluid Soon messa\
ge will be dis-played on the Driver Information Center. Fluid and filter change inter\
vals are based on a combination of factors, including temperature and miles driven. Fluid sh\
ould be changed after every 24 hours of track use. Reset the transmission fluid life s\
ystem every time the fluid is changed. The transmission filter also must be changed a\
t the first oil change interval. Two extra liters of transmission fluid is recommended for tr\
ack use.
RUN-FLAT TIRES
The run-flat tires eliminate the need for a spare tire. The tire desig\
n enables safe
function during and after a loss of pressure for some distance at a mode\
rate speed. Driving only a short distance with a loss of pressure increases the chan\
ce that the tire can be repaired. Contact Roadside Assistance for the nearest run-flat \
tire servicing facility.
SUMMER TIRESF
Your vehicle may be equipped with high-performance summer tires, which h\
ave a special tread and compound that are optimized for maximum dry and wet road perfo\
rmance. The special tread and compound of the tires will have decreased performa\
nce in cold climates and on ice and snow.
Winter or all-season tires are recommended for the vehicle if driving at\
temperatures below approximately 40°F (5°C) or on ice- and snow-covered roads\
.
TIRE TEMPERATURE
The Tire Status page under the Performance menu on the Driver Information Center shows individual tire pressures and overall temperature as either Cold, Cool, Normal, Warm, or Hot. A Normal temperature is typical for normal driving and a Warm temperature is typical for aggressive driving.
TIRE PRESSURE MONITOR
The Low Tire Pressure warning light on the instrument cluster illuminates wh\
en one or more of the vehicle’s tires is significantly underinflated. Fi\
ll the tires to the proper tire pressures listed on the Tire and Loading Information label, located belo\
w the driver’s door latch. Current tire pressures can be viewed on the Driver Informati\
on Center.
Note: Refer to your Owner’s Manual for information about normal monthly tire maintenance.
TIRE FILL ALERT
With the ignition On or in Accessory mode, the Tire Fill Alert will prov\
ide visual and audible alerts when inflating a tire. When the recommended tire pressu\
re is reached, the horn sounds and the turn signal changes from flashing to a solid light\
.
