188 Driving and Operating
Brakes
Antilock Brake
System (ABS)
This vehicle has 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 0112.
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.

Driving and Operating 189
The vehicle has an Electric Parking
Brake (EPB). The EPB can always
be activated, even if the vehicle
is off.
The system has a red parking brake
status light and an amber parking
brake warning light. SeeElectric
Parking Brake Light 0111 and
Service Electric Parking Brake Light
0 112. There are also parking
brake-related Driver Information
Center (DIC) messages. See Brake
System Messages 0133. 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.
2. Pull the EPB switch momentarily. 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 0111.
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 is 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 vehicle in ON/RUN.
2. Apply and hold the brake pedal.
3. Push 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.

190 Driving and Operating
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 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 braking
pressure to hold the vehiclestationary. 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)
Select the duration of the HSA
feature on the center stack
touchscreen by choosing the
submenu for Hill Start Assist or
Extended Hill Start Assist (EHSA).
See
“Extended Hill Start Assist"
under “Comfort and Convenience” in
Vehicle Personalization 0141.
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 safety 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 safety belt
is unbuckled prior to releasing the
brake pedal. When EHSA is
deactivated after five minutes, or if it
is deactivated when the driver
safety 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-
9807421) - 2017 - CRC - 11/18/15
Driving and Operating 191
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 0101 andDriver
Information Center (DIC) 0130.
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.

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
paddles.
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 0192. 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 0166.

selected following gap. The vehicle
speed increases or decreases to
follow the vehicle in front of you, but
will not exceed the set speed. It may
apply limited braking, if necessary.
When braking is active, the brake
lamps will come on. The automatic
braking may feel or sound different
than if the brakes were applied
manually. This is normal.
Stationary or Very Slow-Moving
Objects
{Warning
Adaptive Cruise Control (ACC)
may not detect and react to
stopped or slow-moving vehicles
ahead of you. For example, the
system may not brake for a
vehicle it has never detected
moving. This can occur in
stop-and-go traffic or when a
vehicle suddenly appears due to
a vehicle ahead changing lanes.
Your vehicle may not stop and
could cause a crash. Use caution
when using ACC. Your complete(Continued)
Warning (Continued)
attention is always required while
driving and you should be ready
to take action and apply the
brakes.
ACC Automatically Disengages
ACC may automatically disengage
and the driver will need to manually
apply the brakes to slow the
vehicle when:
. The sensors are blocked.
. The Traction Control System
(TCS) or StabiliTrak system has
activated or been disabled.
. No traffic or other objects are
being detected.
. There is a fault in the system.
The ACC active indicator will not be
displayed when ACC is no longer
active. Notification to Resume ACC
ACC will maintain a following gap
behind a detected vehicle and slow
your vehicle to a stop behind that
vehicle.
If the stopped vehicle ahead has
driven away and ACC has not
resumed, the vehicle ahead
indicator will flash as a reminder to
check traffic before proceeding. In
addition, three beeps will sound.
See
“Go Notifier” in“Collision/
Detection Systems” underVehicle
Personalization 0141.
When the vehicle ahead drives
away, press +RES or the
accelerator pedal to resume ACC.
If stopped for more than
two minutes or if the driver door is
opened and the driver safety belt is
unbuckled, the ACC automatically
applies the Electric Parking Brake
(EPB) to hold the vehicle. The
Electric Parking Brake status light
will turn on. See Electric Parking
Brake 0188. To release the EPB,
press the accelerator pedal.

{Warning
The camera(s) do not display
children, pedestrians, bicyclists,
crossing traffic, animals, or any
other object outside of the
cameras’field of view, below the
bumper, or under the vehicle.
Shown distances may be different
from actual distances. Do not
drive or park the vehicle using
only these camera(s). Always
check behind and around the
vehicle before driving. Failure to
use proper care may result in
injury, death, or vehicle damage.
Parking Assist
With RPA, and if equipped with FPA,
as the vehicle moves at speeds of
less than 8 km/h (5 mph) the
sensors on the bumpers may detect
objects up to 1.8 m (6 ft) behind the
vehicle and 1.2 m (4 ft) in front of the
vehicle within a zone 25 cm (10 in)
high off the ground and below
bumper level. These detection
distances may be shorter during warmer or humid weather. Blocked
sensors will not detect objects and
can also cause false detections.
Keep the sensors clean of mud, dirt,
snow, ice, and slush; and clean
sensors after a car wash in freezing
temperatures.
{Warning
The Parking Assist system does
not detect children, pedestrians,
bicyclists, animals, or objects
located below the bumper or that
are too close or too far from the
vehicle. It is not available at
speeds greater than 8 km/h
(5 mph). To prevent injury, death,
or vehicle damage, even with
parking assist, always check the
area around the vehicle and
check all mirrors before moving
forward or backing.
The instrument cluster may have a
parking assist display with bars that
show
“distance to object” and object
location information for RPA, and on
some vehicles, FPA. As the object
gets closer, more bars light up and
the bars change color from yellow to
amber to red.
When an object is first detected in
the rear, one beep will be heard
from the rear. When an object is
very close (<0.6 m (2 ft) in the
vehicle rear, or <0.3 m (1 ft) in the
vehicle front), five beeps will sound
from the front or rear depending on
object location. Beeps for FPA are
higher pitched than for RPA.

Rear Cross Traffic Alert (RCTA)
If equipped, when the vehicle is
shifted into R (Reverse), RCTA
displays a red warning triangle with
a left or right pointing arrow on the
RVC screen to warn of traffic
coming from the left or right. This
system detects objects coming from
up to 20 m (65 ft) from the left or
right side of the vehicle. When an
object is detected, three beeps
sound from the left or right,
depending on the direction of the
detected vehicle.
Turning the Features On or Off
TheXbutton on the center
console is used to turn on or off the
Front and Rear Parking Assist and
the Rear Cross Traffic Alert (RCTA).
The indicator light in the button
comes on when the features are on
and turns off when the features
have been disabled.
RCTA can also be turned off
through vehicle personalization. See
“Collision/Detection Systems” under
Vehicle Personalization 0141. To turn the RPA symbols or
guidance lines on or off, see
“Rear
Camera” underVehicle
Personalization 0141.
Automatic Parking
Assist (APA)
If equipped, APA searches for and
steers the vehicle into parallel and
perpendicular parking spots. When
using APA, you must still shift gears,
and control the brakes and
accelerator. The Driver Information
Center (DIC) and audible beeps
help to guide parking maneuvers.
{Warning
APA does not apply the brakes.
APA may not detect objects in the
parking space, objects that are
soft or narrow, objects high off the
ground such as flatbed trucks,
or objects below ground level
such as large potholes. Always
verify that the parking space is
appropriate for parking a vehicle.
APA does not respond to changes
(Continued)
Warning (Continued)
in the parking space, such as
movement of an adjacent vehicle,
or a person or object entering the
parking space. APA does not
detect or avoid traffic that is
behind or alongside of the
vehicle. Always be prepared to
stop the vehicle during the
parking maneuver.
Press
Oon the center console to
enable the system to search for a
parking space that is large enough
and within 1.5 m (5 ft) of the vehicle.
The vehicle speed must be below
30 km/h (18 mph).
The system cannot:
. Detect whether it is a legal
parking space.
. Park exactly lined up with the
vehicle next to it if the spot is
approached at an angle or if the
parking space is angled.
. Park exactly centered in a spot
that is marked too large.
