covered by the vehicle warranty.
See Add-On Electrical Equipment
0 214.
Automatic Transmission
Move the shift lever to P (Park) or
N (Neutral). To restart the vehicle
when it is already moving, use
N (Neutral) only.
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped. Manual Transmission
The shift lever should be in Neutral
and the parking brake engaged.
Hold the clutch pedal down to the
floor and start the engine.
Starting the Vehicle
The RKE transmitter must be inside

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 RKE
transmitter is weak, the DIC will
display a message. The vehicle
can still be driven.
See “Starting the Vehicle with a
Low Transmitter Battery” under
Remote Keyless Entry (RKE)
System Operation 028. If the
RKE transmitter battery is
dead, insert it into the steering
column transmitter 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 returning the
ignition to the START position
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.

Leaving the Vehicle with the
Engine Running (Automatic
Transmission)
{Warning
It can be dangerous to leave the
vehicle with the engine running.
It could overheat and catch fire.
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
(Continued)
Warning (Continued)
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
SeeShifting Into Park 0182.
If you have to leave the vehicle with
the engine running, be sure the
vehicle is in P (Park) and the
parking brake is firmly set before
you leave it. After moving the shift
lever into P (Park), hold down the
regular brake pedal. See if you can
move the shift lever away from
P (Park) without first pushing the
button on the lever. If you can, it
means that the shift lever was not
fully locked into P (Park).
Torque Lock (Automatic
Transmission)
If you are parking on a hill and you
do not shift the transmission into
P (Park) properly, the weight of
the vehicle may put too much
force on the parking pawl in the

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11374030) - 2018 - CRC - 11/8/17
Driving and Operating 183
transmission. You may find it difficult
to pull the shift lever out of P (Park).
This is called“torque lock.”To
prevent torque lock, set the parking
brake and then shift into P (Park)
properly before leaving the driver
seat. To find out how, see “Shifting
Into P (Park)” previously in this
section.
When you are ready to drive, move
the shift lever out of P (Park) before
releasing the parking brake.
If torque lock does occur, you may
need to have another vehicle push
yours a little uphill to take some of
the pressure from the transmission
parking pawl, so you can pull the
shift lever out of P (Park).
Shifting out of Park
This vehicle is equipped with an
electronic shift lock control system.
The shift lock release is designed to
prevent movement of the shift lever
out of P (Park), unless the ignition is
on and the brake pedal is applied. The shift lock release is always
functional except in the case of an
uncharged or low voltage (less than
9-volt) battery. See
Jump Starting -
North America 0287.
To shift out of P (Park):
1. Apply the brake pedal.
2. Release the parking brake. See Electric Parking Brake
0 193.
3. Press the shift lever button.
4. Move the shift lever to the desired position.
If you still are unable to shift out of
P (Park): 1. Fully release the shift lever button, and let go of the shift
lever.
2. While holding down the brake pedal, press the shift lever
button again.
3. Move the shift lever to the desired position. If you still cannot move the shift
lever from P (Park), consult your
dealer or a professional towing
service.
Parking (Manual
Transmission)
Before exiting the vehicle, move the
shift lever into 1 (First) or
R (Reverse), and apply the parking
brake. Once the shift lever has been
placed into 1 (First) or R (Reverse)
with the clutch pedal pressed in,
turn the ignition off and release the
clutch.
Parking over Things
That Burn
{Warning
Things that can burn could touch
hot exhaust parts under the
vehicle and ignite. Do not park
over papers, leaves, dry grass,
or other things that can burn.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11374030) - 2018 - CRC - 11/8/17
184 Driving and Operating
Active Fuel Management
This system allows the engine to
operate on either all or half of its
cylinders, depending on the driving
conditions. With a manual
transmission, the system is only
active in Eco Mode. With an
automatic transmission, the system
is available in all modes, but is more
aggressive in Eco Mode. SeeDriver
Mode Control 0198.
When less power is required, such
as cruising at a constant vehicle
speed, the system will operate in
the half cylinder mode, allowing the
vehicle to achieve better fuel
economy. When greater power
demands are required, such as
accelerating from a stop, passing,
or merging onto a freeway, the
system will maintain full-cylinder
operation.
Extended Parking
It is best not to park with the vehicle
running. If the vehicle is left running,
be sure it will not move and there is
adequate ventilation. See Shifting
Into Park 0182 andEngine Exhaust
0 184.
If the vehicle is left parked and
running with the RKE transmitter
outside the vehicle, it will turn off
after one hour.
If the vehicle is left parked and
running with the RKE transmitter
inside the vehicle, it will turn off after
two hours.
The vehicle could turn off sooner if it
is parked on a hill, due to lack of
available fuel.
Automatic Transmission
The timer will reset if the vehicle is
shifted out of P (Park) while it is
running.
Manual Transmission
The timer will reset if the vehicle
speed is greater than 4 km/h
(2.5 mph).
Engine Exhaust
{Warning
Engine exhaust contains carbon
monoxide (CO), which cannot be
seen or smelled. Exposure to CO
can cause unconsciousness and
even death.
Exhaust may enter the vehicle if: . The vehicle idles in areas
with poor ventilation
(parking garages, tunnels,
deep snow that may block
underbody airflow or tail
pipes).
. The exhaust smells or
sounds strange or different.
. The exhaust system leaks
due to corrosion or damage.
. The vehicle exhaust system
has been modified,
damaged, or improperly
repaired.

Downshifting the transmission in
slippery road conditions could result
in skidding. See“Skidding”under
Loss of Control 0159.
The transmission can be shifted like
a manual transmission using the
paddle shift controls while in
D (Drive). See Manual Mode0187.
Caution
A transmission hot message may
display if the automatic
transmission fluid is too hot.
Driving under this condition can
damage the vehicle. Stop and idle
the engine to cool the automatic
transmission fluid. This message
clears when the transmission fluid
has cooled sufficiently.
M : In M (Manual Mode), the
transmission can be shifted like a
manual transmission using the
paddle shift controls. See Manual
Mode 0187.
Manual Mode
Manual Paddle Shift
(Automatic Transmision)
When the shift lever is moved to
M (Manual Mode), the transmission
enters Manual Mode. The
transmission will hold the current
gear until a change is requested.
The paddles on the steering wheel
can be used to manually upshift or
downshift the transmission. The
right (+) plus paddle upshifts, and
the left (−) minus paddle downshifts.
When using the Manual Paddle
Shift feature while in M (Manual
Mode), the current gear will be
displayed in the instrument cluster
or the Head-Up Display (HUD),
if equipped. See Head-Up Display
(HUD) 0121.
When accelerating the vehicle from
a stop in snowy and icy conditions,
shifting to 2 (Second) gear allows
the vehicle to gain more traction.
The Manual Paddle Shift system
can be deactivated by moving the
shift lever from M (Manual Mode)
back to D (Drive).

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

188 Driving and Operating
When the shift lever is in D (Drive),
press either the right (+) plus paddle
or the left (−) minus paddle to place
the transmission in Temporary
Manual Paddle Shift mode. The
gear indicator next to the shift lever,
in the cluster, and in the HUD will
display an M, even though the shift
lever is still in D (Drive). To exit the
system, hold the (+) plus paddle for
more than one second. The system
will return to automatic shifting after
six seconds of cruising at a steady
speed, no manual shifts, no
aggressive cornering, or when the
vehicle comes to a stop.
While the Manual Paddle Shift gear
selection system is active, the
transmission will automatically
downshift through the gears as thevehicle 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 the manual paddle shifts are
used to shift into a different gear,
or D (Drive) is selected.
If the left (−) minus paddle is held
down briefly, the transmission will
downshift to the lowest gear
possible for the vehicle speed. If the
paddle continues to be held as the
vehicle slows, downshifts will
continue to occur as vehicle speed
allows. This feature also works
while in Temporary Manual Paddle
Shift mode, but first press and
release the (−) minus paddle to
enter Temporary Manual Paddle
Shift mode, then press and hold the
(−) minus paddle briefly.
The Manual Paddle Shift system will
not allow an upshift or a downshift if
the vehicle speed is too fast or too
slow, nor will it allow a start from
3 (Third) or higher gear.
If upshifting does not occur when
needed, vehicle speed will be
limited to protect the engine.When a requested shift is denied
due to the speed restrictions shown,
a DIC message will be displayed,
and the current gear remains
displayed in the instrument cluster
and HUD.
Manual Paddle Shift operation is
available for use with cruise control.
See
Cruise Control 0205.
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).
For Vehicles with a 2.41:1 Axle
Ratio (RPO GXB)
. Upshifts to 3 (Third) gear require
approximately 25 km/h (16 mph).
. Upshifts to 4 (Fourth) gear
