Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three
control systems:
.Braking Skid —wheels are not
rolling.
. Steering or Cornering Skid —
too much speed or steering in a
curve causes tires to slip and
lose cornering force.
. Acceleration Skid —too much
throttle causes the driving
wheels to spin.
Defensive drivers avoid most skids
by taking reasonable care suited to
existing conditions, and by not
overdriving those conditions. But
skids are always possible.
If the vehicle starts to slide, follow
these suggestions: .
Ease your foot off the
accelerator pedal and steer the
way you want the vehicle to go.
The vehicle may straighten out.
Be ready for a second skid if it
occurs.
. Slow down and adjust your
driving according to weather
conditions. Stopping distance
can be longer and vehicle
control can be affected when
traction is reduced by water,
snow, ice, gravel, or other
material on the road. Learn to
recognize warning clues —such
as enough water, ice, or packed
snow on the road to make a
mirrored surface —and slow
down when you have any doubt.
. Try to avoid sudden steering,
acceleration, or braking,
including reducing vehicle speed
by shifting to a lower gear. Any
sudden changes could cause
the tires to slide.
Remember: Antilock brakes help
avoid only the braking skid.
Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep-standing or flowing water.
{Warning
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle (Continued)

New Vehicle Break-In
The vehicle does not require a
break-in period. Vehicle break-in is
performed during manufacturing.
Power Button
The vehicle has an electronic
pushbutton start. The POWER
O
light flashes when the driver door is
open and the vehicle is not on. The
flashing light will eventually time out. The light is on steady when in ON/
RUN power mode. When the vehicle
is turned off, the POWER
Olight
will turn off.
The Remote Keyless Entry (RKE)
transmitter must be in the vehicle for
the system to operate. If the vehicle
will not start, place the RKE
transmitter in the transmitter pocket.
See Remote Keyless Entry (RKE)
System Operation 032.
ON/RUN : This position is for
starting and driving. With the vehicle
off, and the brake pedal applied,
pressing POWER
Oonce will place
the vehicle in ON/RUN. When the
READY light is on in the instrument
cluster, the vehicle is ready to be
driven. This could take up to
15 seconds at extremely cold
temperatures. See Vehicle Ready
Light 0121. The engine will only
start if needed. If the vehicle did not
start, the instrument cluster will
display a screen with inactive fuel
and battery gauges. See Starting
and Stopping the Vehicle 0172.

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.
Electric Parking Brake

Chevrolet VOLT Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11349113) - 2018 - crc - 10/12/17
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.

Chevrolet VOLT Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11349113) - 2018 - crc - 10/12/17
188 Driving and Operating
The controller interprets the braking
request and uses regenerative
braking, conventional hydraulic
braking, or a combination of both as
necessary.
The brake controller applies the
hydraulic brakes using a pump. The
pump may be heard during some
braking, such as rapid applies. This
is normal.
SeeWarning Lights, Gauges, and
Indicators 0106 andDriver
Information Center (DIC) 0133.
If there is a controller problem, the
brake pedal may be harder to push
and the stopping distance may be
longer.Regen on Demand
Regen on Demand allows increased
deceleration by pressing and
holding the steering wheel paddle.
It works in D (Drive) and L (Low).
The accelerator pedal must be fully
released for it to work.
The brake pedal must be applied at
low speed, because Regen on
Demand will not bring the car to a
full stop.
Cruise control will turn off, and the
brake lights may come on, when
this feature is activated. The brake controller applies the
hydraulic brakes using a pump. You
may hear the pump during some
braking maneuvers, such as rapid
brake applies or while replacing any
regenerative brake torque as the
vehicle comes to a stop. This is
normal operation.

Ride Control Systems
Traction Control/
Electronic Stability
Control
The vehicle has a Traction Control
System (TCS) and an Electronic
Stability Control system called
StabiliTrak. These systems help
limit wheel slip and assist the driver
in maintaining control, especially on
slippery road conditions.
TCS activates if it senses that any
of the drive wheels are slipping or
beginning to lose traction. When this
happens, TCS applies the brakes to
the spinning wheels and reduces
engine power to limit wheel spin.
StabiliTrak activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak selectively applies
braking pressure to any of the
vehicle wheel brakes to help assist
the driver in keeping the vehicle on
the intended path.If cruise control is being used and
TCS or StabiliTrak begins to limit
wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow.
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 0167
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 is
activated.
. Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate, a message may display in
the Driver Information Center (DIC),
and
dcomes 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.
If
dcomes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.

accelerator pedal to maintain the
vehicle speed. When going
downhill, you might have to brake or
shift to a lower gear to keep your
speed down.
If a lower gear is being used while
going downhill, this causes the
vehicle to have improved control of
vehicle speed by using a
combination of engine and
regenerative braking depending on
vehicle conditions. At times you
might have to apply the brakes to
keep your speed down. If the brake
pedal is applied, cruise control will
disengage.
Ending Cruise Control
There are five ways to end cruise
control:
.Step lightly on the brake pedal.
. Press
*.
. Shift the electric drive unit to
N (Neutral).
. Press
5to turn the cruise
control system off completely. .
Press the Regen on Demand
paddle.
Erasing Speed Memory
The cruise control set speed is
erased from memory if
5is pressed
or if the vehicle is turned off.
Adaptive Cruise Control
If equipped with Adaptive Cruise
Control (ACC), it allows you to
select the cruise control set speed
and following gap. Read this entire
section before using this system.
The following gap is the following
time between your vehicle and a
vehicle detected directly ahead in
your path moving in the same
direction. If no vehicle is detected in
your path, ACC works like regular
cruise control. ACC uses camera
and radar sensors. See Radio
Frequency Statement 0351.
If a vehicle is detected in your path,
ACC can apply acceleration or
limited, moderate braking to
maintain the selected following gap.
To disengage ACC, apply the brake.
If ACC is controlling your vehicle speed when the Traction Control
System (TCS) or StabiliTrak system
activates, the ACC may
automatically disengage. See
Traction Control/Electronic Stability
Control
0189. When road
conditions allow ACC to be safely
used, the ACC can be turned
back on.
ACC will not engage if the TCS or
StabiliTrak system is disabled.
{Warning
ACC has limited braking ability
and may not have time to slow
the vehicle down enough to avoid
a collision with another vehicle
you are following. This can occur
when vehicles suddenly slow or
stop ahead, or enter your lane.
Also see “Alerting the Driver” in
this section. Complete attention is
always required while driving and
you should be ready to take
action and apply the brakes. See
Defensive Driving 0162.
