Starting Procedure
Move the shift lever to P (Park) or
N (Neutral). The propulsion system
will not start in any other position.
Notice:Do not try to shift to
P (Park) if the vehicle is moving
or the electric drive unit could be
damaged. Shift to P (Park) only
when the vehicle is stopped.
Notice: The vehicle is designed
to work with the electronics in the
vehicle. If you add electrical parts
or accessories, you could change
the way the vehicle operates.
Before adding electrical

might not perform properly. Any
resulting damage would not be
covered by the vehicle warranty. The Remote Keyless Entry (RKE)
transmitter must be in the vehicle.
Press the brake pedal and push and
release the POWER
Obutton.
If the RKE transmitter is not in the
vehicle or something is interfering
with the transmitter, a message
displays in the Driver Information
Center (DIC). See Key and Lock
Messages on page 5‑51.
If the vehicle will not start due to a
low RKE transmitter battery, the
vehicle can still be driven. See
“Starting the Vehicle with a Low
Transmitter Battery” inRemote
Keyless Entry (RKE) System

Driving and Operating 9-25
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

Each time the vehicle is started, it
will return to Normal Mode.
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. See
Hill
and Mountain Roads on page 9‑9
and Electric Drive Unit on
page 9‑31.
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 5‑52.

Black plate (27,1)Chevrolet Volt Owner Manual - 2012
Driving and Operating 9-27
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 estimated electric range
will adjust accordingly and any
battery charge reserve still unused
upon exiting Mountain Mode will be
added back to the electric range
display.
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 5‑24.
Each time the vehicle is started, it
will return to Normal Mode to
maintain a smaller battery charge
reserve for normal driving.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

Maintenance Modes
Engine Maintenance Mode (EMM)
Engine Maintenance Mode (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. During
EMM, a DIC message displays to
show the EMM percentage
complete.
If No is selected, the EMM Request
screen will appear when the vehicle
is next started. The EMM request
can be delayed for only one day.
If the EMM request was delayed for
one day, EMM will automatically
start the engine at the next vehicle
start. An EMM Notification screen
will appear in the center stack
display.If the vehicle shuts off during EMM,
it will restart the next time the
vehicle is driven. A message
displays to indicate that EMM is
active.
If EMM is required and the fuel level
is low, EMM 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

Fuel Maintenance Mode (FMM)
Fuel Maintenance Mode (FMM)
tracks average fuel age. Old fuel
can cause engine problems. If low
engine usage causes average fuel
age to exceed approximately
one year, FMM will run the engine to
use up the old fuel. The engine will
run until enough fresh fuel is added
to bring the average fuel age into an
acceptable range. Allowing more old
fuel to be used up by FMM and
adding a larger amount of fresh fuel
will maximize the length of time
before another fuel maintenance
mode is needed. During FMM the
engine may turn on and off.When FMM is needed, the FMM
Request screen appears on the
center stack display at vehicle start.
If Yes is selected, FMM will begin.
FMM will automatically continue at
each vehicle start until fresh fuel is
added.
If No is selected, the FMM Request
screen will appear when the vehicle
is next started. The FMM request
can be delayed for only one day.
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.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. See

9-34 Driving and Operating
Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The
Yswitch is on
the center stack. The EPB can
always be activated, even if the
vehicle is off. To prevent draining
the 12‐volt battery, avoid repeated
cycles of the EPB system when the
vehicle is off. In case of insufficient electrical
power, the EPB cannot be applied
or released.
Before leaving the vehicle, check
the Electric Parking Brake Light to
ensure the parking brake is applied.
EPB Apply
The EPB can be applied anytime
the vehicle is stopped. The EPB is
applied by momentarily lifting up on
the
Yswitch. Once fully applied,
the Electric Parking Brake Light will
be on. While the brake is being
applied, the Electric Parking Brake
Light will flash until full apply is
reached. If the light does not come
on, or remains flashing, have the
vehicle serviced. Do not drive the
vehicle if the Electric Parking Brake
Light is flashing. See your dealer. If the EPB is applied while the
vehicle is in motion, a chime will
sound, and the DIC message
RELEASE PARKING BRAKE will be
displayed. The vehicle will
decelerate as long as the switch is
held in the up position. Releasing
the
Yswitch during the
deceleration will release the parking
brake. If the
Yswitch is held in
the up position until the vehicle
comes to a stop, the EPB will
remain applied.
If the Electric Parking Brake Light
flashes continuously, the EPB is
only partially applied or released,
or there is a problem with the EPB.
The DIC message SERVICE
PARKING BRAKE will be displayed.
If this light flashes continuously,
release the EPB, and attempt to
apply it again. If this light continues
to flash, do not drive the vehicle.
See your dealer.

Driving and Operating 9-35
If the Service Electric Parking Brake
Light is on, the EPB has detected a
system problem and is operating
with reduced functionality. To apply
the EPB when this light is on, lift up
on the
Yswitch and hold it in the
up position. Full application of the
parking brake by the EPB system
may take a longer period of time
than normal when this light is on.
Continue to hold the
Yswitch until
the Electric Parking Brake Light
remains on. If the Service Electric
Parking Brake Light is on, see your
dealer.
If the EPB fails to apply, the rear
wheels should be blocked to
prevent vehicle movement.
For maximum EPB force when
parking on a hill, pull the EPB
switch twice.
EPB Release
To release the EPB, place the
vehicle in ON/RUN, apply and hold
the brake pedal, and push down
momentarily on the
Yswitch.
If attempting to release the EPB
without the brake pedal applied, a
chime will sound, and the DIC
message STEP ON BRAKE TO
RELEASE PARK BRAKE will be
displayed. The EPB is released
when the Electric Parking Brake
Light is off.
If the Service Electric Parking Brake
Light is on, the EPB has detected a
system problem, and is operating
with reduced functionality. To
release the EPB when this light is
on, push down on the
Yswitch
and hold it in the down position.
EPB release may take a longer
period of time than normal when this
light is on. Continue to hold the
Y
switch until the Electric Parking
Brake Light is off. If the light is on,
see your dealer. Notice:
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
Electric Parking Brake 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.

Driving and Operating 9-37
When the vehicle is started and
begins to move, the system
performs several diagnostic checks
to ensure there are no problems.
The system may be heard or felt
while it is working. This is normal
and does not mean there is a
problem with the vehicle. The
system should initialize before the
vehicle reaches 32 km/h (20 mph).
In some cases, it may take
approximately 3.2 km (2 mi) of
driving before the system initializes.
The TCS may activate on dry or
rough roads or under conditions
such as heavy acceleration while
turning or abrupt changes in output
from the electric drive unit. When
this happens, a reduction in
acceleration may be noticed, or a
noise or vibration may be heard.
This is normal.dflashes to indicate that TCS is
active. See Traction Control System
(TCS)/StabiliTrak
®Light on
page 5‑25 for more information.
If there is a problem detected with
TCS, SERVICE TRACTION
CONTROL is displayed on the
Driver Information Center (DIC).
See Ride Control System Messages
on page 5‑53. When this message
is displayed and
dcomes on and
stays on, the vehicle is safe to drive
but the system is not operational.
Driving should be adjusted
accordingly.
If
dcomes on and stays on, reset
the system:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.
If
dstill comes on and stays on, the
vehicle needs service. Notice:
Do not repeatedly brake
or accelerate heavily when TCS is
off. The vehicle's driveline could
be damaged.
TCS can be turned off by pressing
and releasing the TCS/ESC button
located on the overhead console.
When TCS is turned off,
icomes
on, and the appropriate DIC
message also displays. See Ride
Control System Messages on
page 5‑53. With TCS turned off, the
system does not limit wheel spin.
