Electric Vehicle
Operating Modes
System Operation
This vehicle is an Extended Range
Electric Vehicle (EREV). It uses an
electric propulsion system to drive
the vehicle at all times. Electricity is
the vehicle's primary source of
energy, while gasoline is the
secondary source.
The vehicle has two modes of
operation: Electric and Extended
Range. In Electric Mode, the vehicle
is propelled by its electric drive unit
only. It converts electrical energy
into mechanical energy to drive the
wheels. In Extended Range Mode,
both the battery and the engine
power the vehicle. The vehicle's
performance remains nearly the
same in either mode. See Driving
for Better Energy Efficiency 026.

If the FMM request was delayed for
one day, FMM will start at the next
vehicle start and display the FMM
Notification screen on the center
stack display. The engine will not
start until after a short delay once
shifted into D (Drive).
If FMM is required and the fuel level
is low, FMM may eventually empty
the fuel tank if fuel is not added.
This will result in reduced, or no
power. An adequate fuel level must
be maintained in the vehicle to keep
it operational. SeePropulsion Power
Messages 0138. After FMM has
run it is recommended to fill the
fuel tank.
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 engine is running in
Extended Range Mode in
areas with poor ventilation
(parking garages, tunnels,
or 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.
(Continued)
Warning (Continued)
.There are holes or openings
in the vehicle body from
damage or aftermarket
modifications that are not
completely sealed.
If unusual fumes are detected or
if it is suspected that exhaust is
coming into the vehicle: . Drive it only with the
windows completely down.
. Have the vehicle repaired
immediately.
Never park with the engine
running in Extended Range Mode
in an enclosed area such as a
garage or a building that has no
fresh air ventilation.

186 Driving and Operating
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. See
Shifting Into Park0177 andEngine
Exhaust 0185.
Electric Drive Unit
The vehicle uses an electric
drive unit.
P : This position locks the front
wheels. It is the best position to use
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 0177.
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
vehicle is in ON/RUN. If you cannot
shift out of P (Park), ease pressure

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.

9807421) - 2017 - CRC - 11/18/15
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.

194 Driving and Operating
Cruise Control
The cruise control lets the vehicle
maintain a speed of about 40 km/h
(25 mph) or more without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
With the Traction Control System
(TCS) or Electronic Stability Control
(ESC), the system may begin to
limit wheel spin while you are using
cruise control. If this happens, the
cruise control will automatically disengage. See
Traction Control/
Electronic Stability Control 0192.
If a collision alert occurs when
cruise control is activated, cruise
control is disengaged. See Forward
Collision Alert (FCA) System 0208.
When road conditions allow you to
safely use it again, cruise control
can be turned back on.
If the brakes or the Regen on
Demand paddle are applied, cruise
control disengages.
5: Press to turn the cruise control
system on and off. A white indicator
comes on in the instrument cluster
when cruise is turned on.
*: Press to disengage cruise
control without erasing the set
speed from memory.
+RES : If there is a set speed in
memory, press briefly to resume that
speed or press and hold to
accelerate. If cruise control is
already active, use to increase
vehicle speed.
−SET : Press briefly to set the
speed and activate cruise control.
If cruise control is already active,
use to decrease vehicle speed.
Setting Cruise Control

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

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.
