Climate Mode Operation
There are three climate mode
settings: Fan Only, eco, and MAX.
These settings adjust the impact the
climate control system has on the
vehicle's electric range or fuel
economy.
To select a climate mode,
press eco.
Fan Only Mode :
To select this
mode, turn off both eco and MAX
mode. The air conditioning and
electric heat are turned off. As long as
0MAX is not selected, the
climate control settings may not
have a noticeable effect on the
vehicle electric range and fuel
economy.
When in Fan Only mode, the AUTO
indicator light will be on. When
AUTO is selected in Fan Only
mode, the mode will change to
either eco or MAX.
When in Fan Only mode, the air
conditioning system may turn on
automatically if the high voltage
battery is being cooled. The climate
control system could blow cold air.
This is normal. To prevent cold air
from blowing into the interior, turn off
the fan control and select the vent
mode and manual recirculation
mode, and close the air vents.
When in Fan Only mode, if Auto
Defog is enabled, the air
conditioning and electric heat may
turn on when high humidity
conditions exist. See “Climate and
Air Quality” underVehicle
Personalization 0137 for more

economy will decrease less than in
MAX mode, but will result in
moderate comfort.
MAX Mode : Press MAX to select
this mode and the indicator will be
lit. The air conditioning and electric
heat are controlled to reach the best
comfort level based on the
temperature setting selected. In this
mode, vehicle electric range or fuel
economy will decrease depending
on the amount of energy required to
reach the best comfort levels.
The air conditioning and electric
heat could be on at the same time
when dehumidification is required in
eco or MAX modes. The air conditioning may also run if
0MAX is selected, regardless of
the climate mode.
Automatic Operation
The system automatically controls
the fan speed, air delivery mode, air
conditioning, and recirculation to
heat or cool the vehicle to the
selected temperature.

Climate Controls 157
The defogger only works when the
vehicle is on. The defogger will turn
off if the vehicle is turned off.
If equipped 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 Mirrors048.
Caution
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 would not be
covered by the vehicle warranty.
Remote Start : 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
038.
If equipped, the heated seats will
turn on if it is cold outside. The
heated seat indicator light may not
come on during a remote start.
If equipped, the heated steering
wheel will come on if it is cold
outside. The heated steering wheel
indicator light may not come on
during a remote start.
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.
Sensors
Solar Sensor
The solar sensor is on top of the
instrument panel, near the
windshield, where it monitors solar
intensity.
The climate control system uses the
sensor information to adjust the
temperature, fan speed,
recirculation, and air delivery mode
for best comfort.
Do not cover the sensor; otherwise
the automatic climate control system
may not work properly.
Humidity Sensor
The humidity sensor is near the
base of the inside rearview mirror.
The climate control system uses the
sensor information to adjust the
temperature and recirculation for
best comfort.

Warning (Continued)
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
SeeShifting Into Park 0174.
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

Chevrolet VOLT Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11349113) - 2018 - crc - 10/12/17
Driving and Operating 175
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 on, 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 on, the brake pedal is
applied, and the charge cord is
unplugged. Parking the vehicle in extreme cold
for several days without the charge
cord connected may cause the
electric drive unit to be locked in
P (Park) until the propulsion system
has warmed sufficiently.
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.
