Leaving the Vehicle with the
Propulsion System On
{Warning
It can be dangerous to leave the
vehicle with the propulsion
system 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
propulsion system is running.
If you have left the propulsion
system running, the vehicle can
move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when (Continued)
Warning (Continued)
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
SeeShifting Into Park 0174.
If you have to leave the vehicle with
the propulsion system on, be sure
the vehicle is in P (Park) and the
parking brake is firmly set before
you leave it. After you have moved
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 pulling it
toward you. If you can, it means that
the shift lever was not fully locked
into P (Park).
Torque Lock
Torque lock is when the weight of
the vehicle puts too much force on
the parking pawl in the electric drive
unit. This happens when parking on
a hill and shifting the electric drive
unit into P (Park) is not done
properly and then it is difficult to

Chevrolet VOLT Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11349113) - 2018 - crc - 10/12/17
Driving and Operating 175
shift out of P (Park). To prevent
torque lock, set the parking brake
and then shift into P (Park).
If torque lock does occur, your
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so you
can shift out of P (Park).
Shifting out of Park
To shift out of P (Park), the vehicle
must be on, the brake pedal must
be applied, and the charge cord
must be unplugged.
The vehicle has an electronic shift
lock release system. The shift lock
release is designed to:
.Prevent the vehicle from turning
off unless the shift lever is in
P (Park).
. Prevent moving the shift lever
out of P (Park), unless the
vehicle is on, the brake pedal is
applied, and the charge cord is
unplugged. Parking the vehicle in extreme cold
for several days without the charge
cord connected may cause the
electric drive unit to be locked in
P (Park) until the propulsion system
has warmed sufficiently.
The shift lock is always functional
except in the case of an uncharged
or low charged 12-volt battery (less
than 9 volts).
If the vehicle has an uncharged
12-volt battery or a 12-volt battery
with low voltage, try charging or
jump starting the 12-volt battery.
See
Battery - North America 0253
or Jump Starting - North America
0 306.
If the shift lever cannot be moved
out of P (Park): 1. Apply and maintain the regular brakes.
2. Turn the vehicle on using POWER
O. See Power Button
0 171. 3. Let up on the shift lever and
make sure the shift lever is
pushed all the way into
P (Park).
4. Press the shift lever button.
5. Move the shift lever into the desired gear.
If you still cannot move the shift
lever from P (Park), see your dealer
or a professional towing service.
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.

Driving and Operating 183
Running the Vehicle
While Parked
It is better not to park with the
propulsion system running.
If the vehicle is left with the
propulsion system running, follow
the proper steps to be sure the
vehicle will not move.
SeeShifting Into Park 0174 and
Engine Exhaust 0182.
Electric Drive Unit
The vehicle uses an electric
drive unit.
P : This position locks the drive
wheels. Use P (Park) when starting
the propulsion system, because the
vehicle cannot move easily.
{Warning
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
propulsion system is running.
If you have left the propulsion
system running, the vehicle can
move suddenly. You or others
could be injured. To be sure the
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).
See Shifting Into Park 0174.
Make sure the shift lever is fully in
P (Park) before starting the
propulsion system. The vehicle has
an electric drive unit shift lock
control system. The regular brake
must be fully applied first and then
the shift lever button pressed before
shifting from P (Park) when the
ignition is on. If you cannot shift out
of P (Park), ease pressure on the

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 propulsion is active and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
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. SeeAntilock
Brake System (ABS) Warning Light
0 117. 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 that 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
the driver 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 might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.

186 Driving and Operating
The vehicle has an Electric Parking
Brake (EPB). The EPB can always
be activated, even if the ignition is
off. To prevent draining the battery,
avoid repeated cycles of the EPB
system when the engine is not
running.
The system has a
Yor PARK
Electric Parking Brake light, and a
8
Service Parking Brake light.
See Electric Parking Brake Light
0 117 and Service Electric Parking
Brake Light 0117.
Before leaving the vehicle, check for
the
Yor PARK 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.
2. Pull the EPB switch momentarily.
The
Yor PARK light will flash and
then stay on once the EPB is fully
applied. If the
Yor PARK 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
Yor
PARK light is flashing. See your
dealer. See Electric Parking Brake
Light 0117.
If the
8light is on, press and hold
the EPB switch. Continue to hold
the switch until the
Yor PARK
light remains on. If the
8light
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
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. 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 ACC/ ACCESSORY.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the
Y
or PARK light is off.
If the
8light is on, release the EPB
by pressing and holding the EPB
switch. Continue to hold the switch
until the
Yor PARK light is off.
If either light stays on after release
is attempted, see your dealer.

Driving and Operating 187
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.
Hill Start Assist (HSA)
The Hill Start Assist (HSA) feature
will activate when the vehicle is
stopped on a moderate to steep
grade to help prevent it from rolling
in an unintended direction. After the
brake pedal has been released and
before the accelerator pedal has
been pressed, HSA uses brakingpressure to hold the vehicle
stationary. If HSA is holding the
vehicle, a DIC message displays.
HSA will not activate in a forward
drive gear when facing downhill,
or in R (Reverse) when facing uphill.
Extended Hill Start
Assist (EHSA)
To change the duration of the HSA
feature, see
“Extended Hill Start
Assist" under “Comfort and
Convenience” inVehicle
Personalization 0137. When
Standard Hold is selected, the
vehicle is held stationary for up to
two seconds after the brake pedal is
released. When Extended Hold is
selected, the vehicle is held
stationary for up to five minutes
after the brake pedal is released. In
either case, override the hold
feature by pressing the accelerator
pedal and attempting to drive away.
If Hill Start Assist is selected in the
Settings menu, it will hold the
vehicle for two seconds unless the
driver door is opened or the driver
seat belt is unbuckled after releasing the brake pedal.
If Extended Hill Start Assist is
selected, it will hold the vehicle for
five minutes unless the driver door
is opened and the driver seat belt is
unbuckled prior to releasing the
brake pedal. When EHSA is
deactivated after five minutes, or if it
is deactivated when the driver seat
belt is unlatched or the driver door is
opened, the Electric Parking Brake
will engage to prevent vehicle
movement.
Regenerative Braking
Some braking energy from the
moving vehicle is turned back into
electrical energy. This energy is
then stored back into the high
voltage battery system, increasing
energy efficiency.
The hydraulic disc brakes work with
the regenerative braking to ensure
effective braking, such as when a
high braking demand is requested.
