Service Only Mode. Press the
button again to turn the vehicle off.
Starting the Engine
Place the transmission in the
proper gear.
Caution
If you add electrical parts or
accessories, you could change
the way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty.
See
Add-On Electrical
Equipment 0217.
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.
The RKE transmitter must be inside
the vehicle for the ignition to work.
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.
To start the vehicle: 1. For vehicles with an automatic transmission, press the brake
pedal, then press the ENGINE
START/STOP button on the
instrument panel. For vehicles
with a manual transmission,

Driving and Operating 185
press the clutch pedal first,
then press ENGINE
START/STOP.
If there is no RKE transmitter in
the vehicle or if there is
something causing interference
with it, the DIC will display a
message. SeeKey and Lock
Messages 0126.
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 027. If the
remote transmitter battery is
dead, insert it into the steering
column transmitter pocket to
enable engine starting. See
“NO REMOTE KEY WAS
DETECTED PLACE KEY IN
TRANSMITTER POCKET THEN START YOUR
VEHICLE”
underKey and Lock
Messages 0126.
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.
Stopping the Engine
If the vehicle has an automatic
transmission, move the shift lever to
P (Park) and press and hold the
ENGINE START/STOP button on
the instrument panel, until the
engine shuts off. If the shift lever is
not in P (Park), the engine shuts off
and the vehicle goes into the
accessory mode. The DIC displays
SHIFT TO PARK. Once the shift
lever is moved to P (Park), the
vehicle turns off. If the vehicle has a

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
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 you leave
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
you release 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
Shift lock release prevents shifting
out of P (Park) unless the vehicle is
running or in accessory mode 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 0292.
To shift out of P (Park): 1. Apply the brake pedal.
2. Release the parking brake. See Electric Parking
Brake 0197.
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 knob.
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.

196 Driving and Operating
The system is activated and
deactivated by pressing either of the
paddles marked REV MATCH on
the steering wheel. The system
must be activated with each new
ignition cycle.
A gear indicator in the instrument
cluster displays the current gear
selected:.
When ARM is activated, the
gear number is amber.
. When ARM is deactivated, the
gear number is white.
. A white dash indicates that
service is required. ARM will be
disabled, and the malfunction
indicator lamp will be on. See
Malfunction Indicator Lamp
(Check Engine Light) 0108. The
clutch and manual transmission
will continue to operate normally.
ARM will also:
. Be active above 25 km/h
(16 mph).
. Match engine speed up to
5400 rpm.
. Not operate when the
accelerator pedal is applied.
. Be disabled when the coolant
temperature is below
0 °C (32 °F).
Brakes
Antilock Brake
System (ABS)
This vehicle has an Antilock Brake
System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the vehicle begins to drive
away, ABS checks itself.
A momentary motor or clicking noise
may be heard while this test is going
on, and it may even be noticed that
the brake pedal moves a little. This
is normal.
If there is a problem with ABS, this
warning light stays on. See Antilock
Brake System (ABS) Warning
Light 0111.

9956103) - 2017 - crc - 4/28/16
Driving and Operating 197
If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses the wheels are
slowing down. If one of the wheels
is about to stop rolling, the computer
will separately work the brakes at
each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
you steer around the obstacle while
braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You may hear the ABS
pump or motor operating and feel
the brake pedal pulsate. This is
normal.
Braking in Emergencies
ABS allows you to steer and brake
at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The switch is on the
center console. The EPB can
always be activated, even if the
ignition is off. To prevent draining
the battery, avoid repeated cycles of
the EPB when the engine is not
running.
The system has a red parking brake
status light and an amber parking
brake warning light. SeeElectric
Parking Brake Light 0110 and
Service Electric Parking Brake Light
0 111. There are also parking
brake-related Driver Information
Center (DIC) messages. See Brake
System Messages 0122. In case of
insufficient electrical power, the EPB
cannot be applied or released.
Before leaving the vehicle, check
the red parking brake status light to
ensure that the parking brake is
applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
9956103) - 2017 - crc - 4/28/16
198 Driving and Operating
2. Lift up the EPB switchmomentarily.
The red parking brake status light
will flash and then stay on once the
EPB is fully applied. If the red
parking brake status light flashes
continuously, then the EPB is only
partially applied or there is a
problem with the EPB. A DIC
message will display. Release the
EPB and try to apply it again. If the
light does not come on, or keeps
flashing, have the vehicle serviced.
Do not drive the vehicle if the red
parking brake status light is flashing.
See your dealer. See Electric
Parking Brake Light 0110.
If the amber parking brake warning
light is on, lift up on the EPB switch
and hold it up. Continue to hold the
switch until the red parking brake
status light remains on. If the amber
parking brake warning light remains
on, see your dealer.
If the EPB is applied while the
vehicle is moving, the vehicle will
decelerate as long as the switch is held up. If the switch is held up 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.
If the EPB fails to apply, the rear
wheels should be blocked to
prevent vehicle movement.
EPB Release
To release the EPB:
1. Place the ignition in the ACC/ ACCESSORY or ON/RUN/
START position.
2. Apply and hold the brake pedal.
3. Push down momentarily on the EPB switch.
The EPB is released when the red
parking brake status light is off.
If the amber parking brake warning
light is on, release the EPB by
pushing down on the EPB switch and holding it down. 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.
The EPB can also be used to
prevent roll back for vehicles with a
manual transmission taking off on a
hill. When no roll back is desired, an
applied EPB will allow both feet to
be used for the clutch and

While pressing the accelerator pedal
or shortly following the release to
override cruise control, briefly
pressing SET/–will result in cruise
set to the current vehicle speed.
Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain your
speed. When going downhill, you
might have to brake or shift to a
lower gear to keep your speed
down. If the brake pedal is applied,
cruise control will disengage.
Cruise Control in Manual Paddle
Shift Gear Selection
When the vehicle is in M (Manual
Mode) and the manual paddle shift
controls are not being used, cruise
control operates in the same
manner as D (Drive). When the vehicle is in M (Manual
Mode) and the manual paddle shift
controls are being used, cruise
control operates as follows:
.
If cruise control is active and a
gear is selected with the manual
paddle shift controls, the vehicle
speed is maintained in the driver
selected gear and will not
automatically upshift or
downshift the transmission while
the driver ’s gear selection is
active.
. If driving in hilly terrain, cruise
control may not be able to
maintain vehicle speed if an
upshift or downshift is not
selected by the driver. While
driving on hilly terrain and cruise
control is active with a manual
paddle shift gear selection, the
driver must select the proper
gear for the terrain or select D
