Automatic Climate
Control System
The heating, cooling, and ventilation
for the vehicle can be controlled
with this system.
The vehicle may require the use of
an auxiliary heat source under
certain cold conditions. This
provides additional heating and
defrost capability obtained by
running the engine, even if the high
voltage battery is adequately
charged. Under these conditions,
the engine will start and use fuel.
Make sure there is fuel in the tank. Do not allow the vehicle to remain in
extreme temperatures for long
periods without being driven or
plugged in.

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.

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.

158 Climate Controls
Outside Air Temperature Sensor
The outside air temperature sensor
is behind the front grille of the
vehicle. The vehicle uses the sensor
information to display outside air
temperature. The climate control
system uses the information to
adjust the climate system operation.Air Vents
Use the louvers on the air vents to
change the direction of the airflow,
or to open and close off the airflow.
Operation Tips
.Keep all outlets open whenever
possible for best system
performance.
. Keep the path under all seats
clear of objects to help circulate
the air inside the vehicle more
effectively. .
Clear snow off the hood to
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.

162 Driving and Operating
{Warning
Taking your eyes off the road too
long or too often could cause a
crash resulting in injury or death.
Focus your attention on driving.
Refer to the infotainment manual for
more information on using that
system and the navigation system,
if equipped, including pairing and
using a cell phone.
Defensive Driving
Defensive driving means “always
expect the unexpected.” The first
step in driving defensively is to wear
the seat belt. See Seat Belts059.
. 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.
. Allow enough following distance
between you and the driver in
front of you. .
Focus on the task of driving.
Drunk Driving
Death and injury associated with
drinking and driving is a global
tragedy.
{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.
Control of a Vehicle
Braking, steering, and accelerating
are important factors in helping to
control a vehicle while driving.
Braking
Braking action involves perception
time and reaction time. Deciding to
push the brake pedal is perception
time. Actually doing it is
reaction time.
Average driver reaction time is
about three-quarters of a second. In
that time, a vehicle moving at
100 km/h (60 mph) travels 20 m
(66 ft), which could be a lot of
distance in an emergency.
Helpful braking tips to keep in mind
include:
. Keep enough distance between
you and the vehicle in front
of you.
. Avoid needless heavy braking.
. Keep pace with traffic.
Power brake assist is available
unless the 12-volt battery drains or
there is a fault in the brake
computer.

Chevrolet VOLT Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11349113) - 2018 - crc - 10/12/17
Driving and Operating 163
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.

11349113) - 2018 - crc - 10/12/17
164 Driving and Operating
3. Turn the steering wheel to gostraight down the roadway.
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three
control systems:
.Braking Skid —wheels are not
rolling.
. Steering or Cornering Skid —
too much speed or steering in a
curve causes tires to slip and
lose cornering force.
. Acceleration Skid —too much
throttle causes the driving
wheels to spin.
Defensive drivers avoid most skids
by taking reasonable care suited to
existing conditions, and by not
overdriving those conditions. But
skids are always possible.
If the vehicle starts to slide, follow
these suggestions: .
Ease your foot off the
accelerator pedal and steer the
way you want the vehicle to go.
The vehicle may straighten out.
Be ready for a second skid if it
occurs.
. Slow down and adjust your
driving according to weather
conditions. Stopping distance
can be longer and vehicle
control can be affected when
traction is reduced by water,
snow, ice, gravel, or other
material on the road. Learn to
recognize warning clues —such
as enough water, ice, or packed
snow on the road to make a
mirrored surface —and slow
down when you have any doubt.
. Try to avoid sudden steering,
acceleration, or braking,
including reducing vehicle speed
by shifting to a lower gear. Any
sudden changes could cause
the tires to slide.
Remember: Antilock brakes help
avoid only the braking skid.
Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep-standing or flowing water.
{Warning
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle (Continued)
