carbon monoxide, see Engine
Exhaust on page 9-27.
To conserve energy, run the vehicle
for only short periods as needed to
warm the vehicle and then shut the
vehicle off and close the window
most of the way to save heat.
Repeat this until help arrives but
only when you feel really
uncomfortable from the cold. Moving
about to keep warm also helps. If it takes some time for help to
arrive, start the vehicle. The engine
may start to charge the 12-volt
battery. Turn off unnecessary
accessories to conserve energy.If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
The Traction Control System (TCS)
must be turned off by pressing the
TCS/ESC button. Traction control is
not completely off, but will only
engage if the maneuver can cause
damage to the electric drive unit.
{Warning
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other

Warning (Continued)
damage. Spin the wheels as little
as possible and avoid going
above 56 km/h (35 mph).
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Shift back and forth
between R (Reverse) and a forward
gear, spinning the wheels as little as
possible. The Traction Control
System prevents the tires from
spinning at high speeds. To prevent
electric drive unit wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator
pedal while shifting, and press
lightly on the accelerator pedal
when the electric drive unit is
in gear. Slowly spinning the wheels
in the forward and reverse
directions causes a rocking
motion that could free the vehicle.

{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.
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 both modes, the vehicle
is propelled by its electric drive unit.
It converts electrical energy into
mechanical energy to drive the
wheels. The vehicle's performance
remains the same in either mode.
See Driving for Better Energy
Efficiency on page 9-2.

9-22 Driving and Operating
Electric Mode
In Electric Mode, the vehicle does
not use fuel or produce tailpipe
emissions. During this primary
mode, the vehicle is powered by
electrical energy stored in the high
voltage battery. The vehicle can
operate in this mode until the
battery has reached a low charge.
There are some conditions when the
battery charge is high enough to
provide Electric Mode operation, but
the engine still runs. They are:
.Cold ambient temperatures.
.Hot or cold high voltage battery
temperatures.
.The hood being open or not
completely closed and latched.
.Certain high voltage battery fault
conditions.
.Engine Maintenance Mode or
Fuel Maintenance Mode
being run.
Extended Range Mode
When the vehicle reaches the end
of its electric range, it switches to
Extended Range Mode (ERM). In
this secondary mode, electricity is
produced by the fuel‐powered
engine. This secondary source of
electric power extends the vehicle
range. Operation will continue in
ERM until the vehicle can be
plugged in to recharge the high
voltage battery and restore
Electric Mode.
The high voltage battery will
continue to provide some power and
work together with the engine to
provide peak performance when it is
required, such as driving up a steep
incline or for high acceleration
maneuvers. The battery will not be
charged nor will electric vehicle
range be restored by the engine.In either Electric Mode or Extended
Range Mode, when the hood is
open, the engine will run without
turning off if the vehicle is on. The
high voltage battery is neither
charged nor discharged when this
occurs.
In either Electric Mode or Extended
Range Mode, if there is a high
voltage battery fault, the engine may
run without turning off to generate
needed electricity. The malfunction
indicator lamp will turn on. See
Malfunction Indicator Lamp on
page 5-19.
Driver Selected Operating
Modes
While driving in Electric or Extended
Range Mode, additional operating
modes can be selected.

9-24 Driving and Operating
Mountain Mode
Mountain Mode should be selected
at the beginning of a trip before
climbing steep, uphill grades and
when expecting to drive in very hilly
or mountainous terrain. This mode
maintains a reserve electrical
charge of the high voltage battery to
provide better grade climbing
performance. While driving in
Mountain Mode, the vehicle will
have less responsive acceleration.
Mountain Mode will not change
normal vehicle braking performance
for steep downhill grades. SeeHill
and Mountain Roads on page 9-9
and Electric Drive Unit on
page 9-28. Press the DRIVE MODE button to
select Mountain Mode. If steep hill
driving is expected, it is
recommended to select Mountain
Mode at least 20 minutes before
driving on steep grades. This will
allow the vehicle time to build a
sufficient battery charge reserve.
If Mountain Mode is not selected for
these conditions, propulsion power
may be reduced and the engine
speed may increase. See
Propulsion Power Messages on
page 5-50.
The engine may run when Mountain
Mode is selected, depending on
high voltage battery charge, to build
reserve battery charge for uphill
climbs. If Mountain Mode is entered
with a sufficient battery charge
reserve, the battery charge reserve
will appear grayed out and any
battery charge reserve still unused
upon exiting Mountain Mode will
return to normal appearance.
Press the Drive Mode button again
to return to Normal Mode and it
becomes active after three seconds.
The Mountain light comes on when
Mountain Mode is selected. See
Mountain Mode Light on page 5-23.
Each time the vehicle is started, it
will return to Normal Mode to
maintain a smaller battery charge
reserve for normal driving.Hold Mode
Hold Mode is only available when
the vehicle is in Electric Mode. This
mode places the remaining battery
charge into a reserve for the driver
to use as desired. Selecting this

(25,1)Chevrolet VOLT Owner Manual (GMNA-Localizing-U.S./Canada-6014139) -
2014 - CRC - 9/16/13
Driving and Operating 9-25
mode transitions the vehicle to
Extended Range Mode to maintain
the battery charge reserve.
Upon exiting Hold Mode, the
reserved battery charge becomes
available again and the vehicle
returns to Electric Mode. If the
transition is from Hold Mode directly
to Mountain Mode, the electric
range displayed adjusts for the
Mountain Mode charge reserve.
Hold Mode will not change normal
vehicle acceleration or braking
performance.
Press the DRIVE MODE button to
select Hold Mode.
Press the DRIVE MODE button
again to return to Normal Mode and
it becomes active after
three seconds.
The Hold light comes on when Hold
Mode is selected. SeeHold Mode
Light on page 5-23.
Each time the vehicle is started, it
will return to Normal Mode.Out of Fuel/Engine
Unavailable
If the vehicle runs out of fuel, or the
engine will not start due to a
malfunction, the vehicle can
continue to be driven in Electric
Mode. The vehicle will have less
responsive acceleration. DIC
messages indicate reduced
propulsion power, that the engine is
not available, and the need for fuel
or service.
Once the vehicle is refueled, or the
malfunction is corrected, the engine
will start the next time the vehicle is
turned on to perform a self test, and
DIC messages will not be displayed.
Once the engine starts successfully,
normal operation will continue in
either Electric or Extended Range
Mode. The engine will stop running
after the self test is completed, and
based on the current mode of
operation. See Fuel System
Messages on page 5-48 and
Service Vehicle Messages on
page 5-52.
Maintenance Modes
Engine Maintenance Mode (EMM)
EMM runs the engine to keep it in
good working condition after
approximately six weeks of no or
very limited engine operation. EMM
will force the engine to run, even if
there is a charge to power the
vehicle. When EMM is needed, the
EMM Request screen appears on
the center stack display at vehicle
start.
If Yes is selected, EMM will begin.
The engine will run for a set
amount of time without turning off.
