Driving and Operating 9-3
Drive Mode and PRNDL Selection
Use Normal Mode when possible.
Sport Mode provides more
responsive acceleration than
Normal Mode but can reduce
efficiency.
Use Mountain Mode prior to
climbing long, steep grades in
mountainous areas. Be sure to
engage Mountain Mode before
starting to climb. Mountain Mode
reduces electric range and power
but may be needed to maintain
speeds above 96 km/h (60 mph)
when climbing grades of 5% or
greater.
Use L (Low) in heavy stop‐and‐go
traffic or when traveling downhill.
L (Low) requires less brake
pedal application and provides
a controlled, efficient way to
slow the vehicle down.Climate Setting
Using the heat and air conditioning
systems decreases the energy
available for electric driving.
Optimal energy efficiency is
achieved with the heat, air
conditioning, and fan turned off.
Less energy is used at low fan
speeds. When using the fan:
.Fan Only is the most energy
efficient climate setting as long
as
0is not selected.
.ECO is for moderate air
conditioning and heater
operation and is the next
most energy efficient setting as
long as
0is not selected.
.Comfort provides the most
comfort but is the least energy
efficient.
Use the auto heated seat feature
instead of climate settings. Heating
the seat uses less energy than
heating the vehicle interior. Use remote start to heat or cool the
interior when the vehicle is plugged
in to maximize the electric range by
utilizing electricity from the electrical
outlet.
In hot weather, avoid parking in
direct sunlight or use sunshades
inside the vehicle.
Turn off the front and rear window
defog/defrost when they are no
longer needed.
Avoid driving with the windows open
at highway speeds.
Vehicle Charging/Maintenance
Charging
Keep the vehicle plugged in, even
when fully charged, to keep the
battery temperature ready for the
next drive. This is important when
outside temperatures are extremely
hot or cold.

Black plate (4,1)Chevrolet Volt Owner Manual - 2011
9-4 Driving and Operating
Maintenance
Always keep the tires properly
inflated and the vehicle properly
aligned.
The weight of excess cargo in the
vehicle affects efficiency and range.
Avoid carrying more than is needed.
If fuel is not regularly used, consider
keeping the fuel tank only one‐third
full. Excess fuel weight impacts
efficiency and range.
Use premium fuel.
Avoid unnecessary use of electrical
accessories. Power used for
functions other than propelling
the vehicle will reduce EV range.
Using a rooftop carrier will reduce
efficiency due to additional weight
and drag.Defensive Driving
Defensive driving means“always
expect the unexpected.” The first
step in driving defensively is to wear
the safety belt. See Safety Belts on
page 3‑10.
{WARNING
Assume that other road users
(pedestrians, bicyclists, and other
drivers) are going to be careless
and make mistakes. Anticipate
what they might do and be ready.
In addition:
.Allow enough following
distance between you and
the driver in front of you.
.Focus on the task of driving.
Driver distraction can cause
collisions resulting in injury or
possible death. These simple
defensive driving techniques
could save your life.
Drunk Driving
{WARNING
Drinking and then driving is
very dangerous. Your reflexes,
perceptions, attentiveness, and
judgment can be affected by
even a small amount of alcohol.
You can have a serious —or
even fatal —collision if you
drive after drinking.
Do not drink and drive or ride with
a driver who has been drinking.
Ride home in a cab; or if you are
with a group, designate a driver
who will not drink.
Death and injury associated with
drinking and driving is a global
tragedy.

Black plate (6,1)Chevrolet Volt Owner Manual - 2011
9-6 Driving and Operating
And, of course, actual stopping
distances vary greatly with the
surface of the road, whether it is
pavement or gravel; the condition
of the road, whether it is wet, dry,
or icy; tire tread; the condition of the
brakes; the weight of the vehicle;
and the amount of brake force
applied.
Avoid needless heavy
braking. Some people drive in
spurts—heavy acceleration
followed by heavy braking —rather
than keeping pace with traffic.
This is a mistake. The brakes
might not have time to cool between
hard stops. The brakes will wear
out much faster with a lot of heavy braking. Keeping pace with the
traffic and allowing realistic following
distances eliminates a lot of
unnecessary braking. That means
better braking and longer brake life.
If propulsion is disabled while
the vehicle is being driven, brake
normally but do not pump the
brakes. If the brakes are pumped,
the pedal could get harder to push
down. If propulsion stops, there
will still be some power brake assist
but it will be used when the brake
is applied. Once the power assist is
used up, it can take longer to stop
and the brake pedal will be harder
to push.Steering
Electric Power Steering
If propulsion is disabled, the power
steering assist system may continue
to operate until you are able to stop
the vehicle. If power steering assist
is lost because the electric power
steering system is not functioning,
the vehicle can be steered but it
will take more effort.
The electric power steering
system does not require regular
maintenance. If you suspect
steering system problems and/or
the SERVICE POWER STEERING
message comes on, contact your
dealer for service. See
Service
Vehicle Messages on page 5‑51.

9-22 Driving and Operating
Restarting Procedure
If the vehicle must be restarted
while it is still moving, move the
shift lever to N (Neutral) and
press the POWER
Obutton twice
without pressing the brake pedal.
The propulsion system will not
restart in any other position.
Computers determine when the
engine needs to run. The engine
may start, if required, when the
propulsion system is on. Some
vehicle conditions that force the
engine to run are:
.Cold ambient temperatures.
.The hood is open or not
completely latched.
.The high voltage battery has a
low charge.
.The engine is needed to
maintain the high voltage
battery temperature.
.The engine needs to run for
maintenance. See
Maintenance Modes on
page 9‑28.
A chime will sound if the driver
door is opened while the vehicle
is in ON/RUN. Always press the
POWER
Obutton to turn the
vehicle off before exiting.
Stopping Procedure
For information on how to turn the
vehicle off, see Power Button on
page 9‑18.
Retained Accessory
Power (RAP)
The following features will operate
for up to 10 minutes or until the
driver door is opened:
.Audio System
.Power Windows
.Accessory Power Outlets
Shifting Into Park
{WARNING
It can be 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. If you have left the propulsion
system on, 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, use the steps
that follow.
1. Hold the brake pedal down and set the parking brake.
See Electric Parking Brake on
page 9‑35 for more information.
2. Move the shift lever into P (Park) by pushing the lever all the way
toward the front of the vehicle.
3. Turn the vehicle off.

Black plate (25,1)Chevrolet Volt Owner Manual - 2011
Driving and Operating 9-25
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 5‑21.
