154 Climate Controls
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 will 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 will 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.
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.

.Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and
the road creates less traction or
grip, so drive carefully. Wet ice can
occur at about 0 °C (32 °F) when
freezing rain begins to fall. Avoid
driving on wet ice or in freezing rain
until roads can be treated.
For slippery road driving:
.Accelerate gently. Accelerating
too quickly causes the wheels to
spin and makes the surface
under the tires slick.
. Turn on Traction Control. See
Traction Control/Electronic
Stability Control 0186.
. The Antilock Brake System
(ABS) improves vehicle stability
during hard stops, but the
brakes should be applied sooner than when on dry pavement.
See
Antilock Brake System
(ABS) 0182.
. Allow greater following distance
and watch for slippery spots. Icy
patches can occur on otherwise
clear roads in shaded areas.
The surface of a curve or an
overpass can remain icy when
the surrounding roads are clear.
Avoid sudden steering
maneuvers and braking while
on ice.
. Turn off cruise control.
. Select All-Wheel Drive (AWD)
Mode for vehicles equipped with
AWD. Select Snow/Ice Mode for
FWD only vehicles. See Driver
Mode Control 0188.
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby.
If possible, use Roadside
Assistance. See Roadside
Assistance Program 0339. 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.
If the vehicle is stuck in snow:
. Clear snow from the base of
the vehicle, especially any
blocking the exhaust pipe.
. Open a window about 5 cm
(2 in) on the vehicle side
that is away from the wind,
to bring in fresh air.
. Fully open the air outlets on
or under the instrument
panel.

164 Driving and Operating
Warning (Continued)
.Adjust the climate control
system to circulate the air
inside the vehicle and set
the fan speed to the highest
setting. See “Climate
Control Systems.”
For more information about CO,
see Engine Exhaust 0180.
To save fuel, start the vehicle for
short periods to warm the vehicle
and then shut the engine off and
partially close the window. Moving
about to keep warm also helps.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
The Traction Control System (TCS)
must be turned off by pressing the
TCS/ESC button. Traction control is
not completely off, but will only
engage if the maneuver can cause
damage to the electric drive unit.
{Warning
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 56 km/h (35 mph).
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Shift back and forth
between R (Reverse) and a forward
gear, spinning the wheels as little as
possible. The Traction Control
System prevents the tires from
spinning at high speeds. To prevent
electric drive unit wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator
pedal while shifting, and press
lightly on the accelerator pedal
when the electric drive unit is in
gear. Slowly spinning the wheels in the forward and reverse directions
causes a rocking motion that could
free the vehicle. If that does not get
the vehicle out after a few tries, it
might need to be towed out. If the
vehicle does need to be towed out,
see
Towing the Vehicle 0305.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can
carry. This weight is called the
vehicle capacity weight and
includes the weight of all
occupants, cargo, and all
nonfactory-installed options.
Two labels on the vehicle may
show how much weight it may
properly carry: the Tire and
Loading Information label and
the Certification label.

Electric Vehicle
Operating Modes
System Operation
This vehicle is an Extended Range
Electric Vehicle (EREV). It uses an
electric propulsion system to drive
the vehicle at all times. Electricity is
the vehicle's primary source of
energy, while gasoline is the
secondary source.
The vehicle has two modes of
operation: Electric and Extended
Range. In Electric Mode, the vehicle
is propelled by its electric drive unit
only. It converts electrical energy
into mechanical energy to drive the
wheels. In Extended Range Mode,
both the battery and the engine
power the vehicle. The vehicle's
performance remains nearly the
same in either mode. See Driving
for Better Energy Efficiency 027.
