improve visibility and help
decrease moisture drawn into
the vehicle.
. Do not use non-GM approved
hood deflectors. They can
adversely affect the performance
of the system.
. Do not attach any devices to the
air vent slats. This restricts
airflow and may cause damage
to the air vents.

Service
All vehicles have a label underhood
that identifies the refrigerant used in
the vehicle. The refrigerant system
should only be serviced by trained
and certified technicians. The air
conditioning evaporator should
never be repaired or replaced by
one from a salvage vehicle.
It should only be replaced by a new
evaporator to ensure proper and
safe operation.
During service, all refrigerants
should be reclaimed with proper
equipment. Venting refrigerants
directly to the atmosphere is harmful
to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite,
or other health-based concerns.
The air conditioning system requires
periodic maintenance. See
Maintenance Schedule 0321.

160 Driving and Operating
Steering
Electric Power Steering
The vehicle has electric power
steering. It does not have power
steering fluid. Regular maintenance
is not required.
If power steering assist is lost due
to a system malfunction, the vehicle
can be steered, but may require
increased effort.
If the steering assist is used for an
extended period of time while the
vehicle is not moving, power assist
may be reduced.
If the steering wheel is turned until it
reaches the end of its travel and is
held against that position for an
extended period of time, power
steering assist may be reduced.
Normal use of the power steering
assist should return when the
system cools down.
See your dealer if there is a
problem.
Curve Tips
.Take curves at a reasonable
speed.
. Reduce speed before entering a
curve.
. Maintain a reasonable steady
speed through the curve.
. Wait until the vehicle is out of
the curve before accelerating
gently into the straightaway.
Steering in Emergencies
.There are some situations when
steering around a problem may
be more effective than braking.
. Holding both sides of the
steering wheel allows you to turn
180 degrees without removing
a hand.
. The Antilock Brake System
(ABS) allows steering while
braking.
Off-Road Recovery
The vehicle's right wheels can drop
off the edge of a road onto the
shoulder while driving. Follow
these tips:
1. Ease off the accelerator and then, if there is nothing in the
way, steer the vehicle so that it
straddles the edge of the
pavement.
2. Turn the steering wheel about one-eighth of a turn, until the
right front tire contacts the
pavement edge.

174 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 and the vehicle is moving at
low speed or stopped, the engine
will run without turning off if the
vehicle is on, except when the electric drive unit is in N (Neutral).
The engine will turn off or remain off
at low vehicle speed in N (Neutral).
The high voltage battery is not
charged when this occurs. Under
these conditions, the high voltage
battery can still be discharged
based on the vehicle loads such as
A/C, or 12-volt loads.
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 (Check
Engine Light)
0114.
Driver Selected Operating
Modes
While driving in Electric or Extended
Range Mode, additional operating
modes can be selected.

Chevrolet VOLT Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12163007) - 2019 - CRC - 11/5/18
Driving and Operating 177
Mode mainly during highway or high
speed driving to maximize both EV
miles and fuel efficiency.
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
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 MODE to select Hold Mode.
Press MODE again to return to
Normal Mode and it becomes active
after three seconds.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 until the current charge is
depleted. The vehicle will have less
responsive acceleration. Driver
Information Center (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 may stop running
after the self test is completed,
based on the current mode of
operation.
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
notification will display.
If Start is selected, EMM will begin.
The engine will not start until after a
short delay once shifted into
D (Drive). 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 More Info is selected, a pop-up
will show describing the Engine
Maintenance procedure. There will
be an option to Start or an option to
Postpone. Postpone will allow EMM
to be delayed for up to one day and
the EMM notification will re-appear
when the vehicle is next started.
If the EMM request was delayed for
one day, EMM will automatically
start the engine at the next vehicle
start, and a notification will display
stating that EMM is starting
maintenance. A More Info button will
also be available on the notification
which, when pressed, provides an
explanation of Engine Maintenance.The engine will not start until after a
short delay once shifted into
D (Drive).
If the vehicle is shut off during EMM,
it will restart the next time the
vehicle is driven and a notification
will display showing that
maintenance is being resumed now.
A message displays to indicate that
EMM is active and a notification will
display showing that maintenance is
being resumed now.
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. See
Propulsion Power
Messages 0136.
Fuel Maintenance Mode (FMM)
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
notification will display.
If Start is selected, FMM will begin.
The engine will not start until after a
short delay once shifted into
D (Drive). FMM will automatically
continue at each vehicle start until
fresh fuel is added.
If More Info is selected, a pop-up
will show describing the Fuel
Maintenance procedure. There will
be an option to Start or an option to
Postpone. Postpone will allow FMM
to be delayed for up to one day and
the FMM notification will re-appear

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
infotainment display. The engine will
not start until after a short delay
once shifted into D (Drive).
A More Info button will also be
available on the notification which,
when pressed, provides an
explanation of Fuel Maintenance.
If the vehicle is shut off during FFM,
it will restart the next time the
vehicle is driven and a notification
will display showing that
maintenance is being resumed now.
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
