8-8 Climate Controls
Rear Window Defogger
=(Rear Window Defogger):
Press to turn the rear window
defogger on or off.
The rear window defogger
turns off automatically after about
five minutes. If turned on again,
it runs for about five minutes
before turning off. The defogger
can also be turned off by turning
the vehicle off.
For vehicles with heated outside
rearview mirrors, they turn on when
the rear window defogger button
is on and help to clear fog or frost
from the surface of the mirror.
See Heated Mirrors on page 2‑16. Notice:
Do not try to clear frost
or other material from the inside
of the front windshield and rear
window with a razor blade or
anything else that is sharp.
This may damage the rear
window defogger grid and affect
the radio's ability to pick up
stations clearly. The repairs
wouldn't be covered by the
vehicle warranty.
Remote Start: For vehicles with
this feature, the climate control
system may be started by using
the Remote Keyless Entry (RKE)
transmitter. The climate control
system will default to an appropriate
heating or cooling mode.
See Remote Start on page 2‑8.
The rear window defogger turns on
if it is cold outside.
Compressor
The vehicle has an electric powered
air conditioning compressor.
This allows for continuous air
conditioning and/or high voltage
battery cooling operation, without
running the engine.
The compressor operating speed
is not tied to the engine speed, so
some noise may be heard from the
compressor, especially when air
conditioning use is high and the
engine has turned off. This is
normal.

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.

9-12 Driving and Operating
Blizzard Conditions
Being stuck in snow can be
a serious situation. Stay with
the vehicle unless there is help
nearby. If possible, use the
Roadside Assistance Program.
To get help and keep everyone
in the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{WARNING
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
Carbon Monoxide (CO) which
cannot be seen or smelled. It can
cause unconsciousness and even
death.(Continued)
WARNING (Continued)
If the vehicle is stuck in the snow:
.Clear away snow from
around the base of the
vehicle, especially any that
is blocking the exhaust pipe.
.Check again from time to
time to be sure snow does
not collect there.
.Open a window about 5 cm
(2 in) on the side of the
vehicle that is away from
the wind to bring in fresh air.
.Fully open the air outlets
on or under the instrument
panel.
.Adjust the climate control
system to a setting that
circulates the air inside
the vehicle and set the fan
speed to the highest setting.
See Climate Control Systems
in the Index.(Continued)
WARNING (Continued)
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑30.
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.

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 (23,1)Chevrolet Volt Owner Manual - 2011
Driving and Operating 9-23
Leaving the Vehicle with the
Propulsion System On
{WARNING
It can be dangerous to leave
the vehicle with the propulsion
system on. The vehicle could
move suddenly if the shift lever
is not fully in P (Park) with the
parking brake firmly set. And,
if you leave the vehicle with the
propulsion system on, it could
overheat and even catch fire.
You or others could be injured.
Do not leave the vehicle with
the propulsion system on.
If you have to leave the vehicle with
the propulsion system on, be sure
the vehicle is in P (Park) and the
parking brake is firmly set before
you leave it. After you have moved the shift lever into P (Park), hold
down the regular brake pedal.
See if you can move the shift lever
away from P (Park) without first
pulling it toward you. If you can,
it means that the shift lever was
not fully locked into P (Park).
Torque Lock
Torque lock is when the weight of
the vehicle puts too much force on
the parking pawl in the electric drive
unit. This happens when parking
on a hill and shifting the electric
drive unit into P (Park) is not done
properly and then it is difficult to
shift out of P (Park). To prevent
torque lock, set the parking brake
and then shift into P (Park).
If torque lock does occur, your
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so you
can shift out of P (Park).
Shifting out of Park
To shift out of P (Park), the vehicle
must be in ON/RUN, the brake
pedal must be applied, and the
charge cord must be unplugged.
The vehicle has an electronic shift
lock release system. The shift lock
release is designed to:
.Prevent the vehicle from turning
off unless the shift lever is in
P (Park).
.Prevent moving the shift lever
out of P (Park), unless the
vehicle is in ON/RUN, the brake
pedal is applied, and the charge
cord is unplugged.
The shift lock is always functional
except in the case of an uncharged
or low charged 12‐volt battery
(less than 9 volts).
If the vehicle has an uncharged
12‐volt battery or a 12‐volt battery
with low voltage, try charging or
jump starting the 12‐volt battery.
See Jump Starting on page 10‑79.
