Control System
The climate control buttons and the
touch screen are used to adjust the
heating, cooling, and ventilation.
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
being plugged in.

Climate Controls 8-5
The air conditioning and electric
heat could be on at the same time
when dehumidification is required in
ECO or Comfort modes.
In Fan Only mode, occasionally the
air conditioning and/or heating
status will be on if the Auto Defog
function is enabled and high
humidity is detected. See“Climate
and Air Quality” underVehicle
Personalization on page 5-54, for
details on enabling or disabling the
Auto Defog function.
The air conditioning may also run if
0is selected, regardless of the
climate mode.
Automatic Operation
The system automatically controls
the fan speed, air delivery mode,
and recirculation to heat or cool
the vehicle to the selected
temperature.
When the AUTO indicator light is
on, the system is in full automatic
operation. If the air delivery mode, fan speed, or recirculation setting is
adjusted, the AUTO indicator turns
off and the selected settings display.
For automatic operation:
1. Press AUTO.
2. Set the temperature. An initial
setting of 23°C (74°F) is
recommended. Allow the system
time to stabilize. Adjust the
temperature as needed.
Q/R(Temperature Control):
Press to increase or decrease the
temperature.
Auto Defog: The system will
monitor high humidity inside the
vehicle. When high humidity is
detected, the climate control system
may adjust to outside air supply and
turn on the air conditioner or the
heater. The fan speed may slightly
increase to help prevent fogging.
When high humidity is no longer
detected, the system will return to
its prior operation. To turn Auto Defog off or on, see
“Climate and
Air Quality” underVehicle
Personalization on page 5-54.
Manual Operation
A(Fan Control): Press the fan
control buttons or the touch screen
fan control, to increase or decrease
the fan speed. The fan speed
setting displays. Pressing either
button cancels automatic fan control
and the fan can be controlled
manually. Press AUTO to return to
automatic operation. Press the fan
down button repeatedly to turn off
the fan and the climate control
system.
If the fan is manually turned off
while in ECO or Comfort mode, the
display will automatically change to
Fan Only mode. When the fan is
turned back on either by manually
increasing fan speed or pressing the
AUTO button, the climate mode will
revert back to ECO or
Comfort mode.

MAUTO/LAUTO (Auto Heated
Seats): If available, the controls
are on the touch screen on the
center stack.
Press the touch screen
LAUTO or
MAUTO button. The button color
will change to green when this
feature is on. When the vehicle is
on, this feature will automatically
activate the heated seats at the
level required by the vehicle's
interior temperature. The active
high, medium, low, or off heated
seat level will be indicated by the
manual heated seat button lights on
the center stack. Use the touch
screen buttons or the manual
heated seat buttons on the center
stack to turn auto heated seats off.
For more information, see Heated
Front Seats on page 3-5.
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.
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 Mirrors on page 2-17.
{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:
If equipped 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.

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 Hold Mode on a trip where all
or most of the electric charge will be
depleted. Use Hold Mode mainly
during highway or high speed
driving to maximize both EV miles
and fuel efficiency.
Use L (Low) in heavy stop-and-go
traffic or when traveling downhill.
L (Low) requires less brake pedalapplication 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.
Engine Assisted Heating operation,
if equipped, can be personalized.
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 Personalization on
page 5-54.

{Warning
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the vehicle if there is a
leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
If there seems to be no leak, with
the engine on, check to see if the
cooling fans are running. If the
engine is overheating, the fans
should be running. If it is not, the
vehicle needs service. Turn off the
vehicle.
Cooling System (High
Voltage Battery)
During vehicle operation and also
during charging, the high voltage
battery cells in the vehicle are kept within a normal operating
temperature range. If the
temperature rises above this
temperature, the battery cooling
system turns on the air conditioning
compressor and cools the coolant
until the correct temperature is
reached. If the temperature falls
below this temperature, a high
voltage heater, located in the
battery, heats the coolant until the
correct temperature is reached.
What to Use
The high voltage battery coolant
reservoir in the vehicle is filled with
a 50/50 mixture of DEX-COOL
®
engine coolant and deionized water.
If using this mixture, nothing else
needs to be added.
The coolant needs to be replaced at
the appropriate interval. See
Maintenance Schedule on
page 11-2.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
The high voltage battery coolant
reservoir is located in the engine
compartment. See
Engine
Compartment Overview on
page 10-8.
Check to see if coolant is visible in
the high voltage battery coolant
reservoir. If coolant is visible but the
