Fan Only Mode:The air
conditioning and electric heat are
turned off. As long as
0is 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 off. When
AUTO is selected in Fan Only
mode, the mode will change to
either ECO or Comfort.
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 on page 5-54 for
more information on the Auto Defog
selection. The air conditioning may
also run if
0is selected.
ECO Mode: The air conditioning
and electric heat are controlled to
balance comfort with fuel economy.
As long as
0is not selected, the
vehicle electric range or fuel
economy will decrease less than in
Comfort mode, but will result in
moderate comfort.
Comfort Mode: 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.
Climate Power Gauge
When the climate mode is changed,
the Climate Power gauge displays
the impact that user setting changes
have on energy consumption. The
higher the reading, the more energy
is being used.
Air Conditioning/Heat Status Indicators
The air conditioning/heat status
displays when the air conditioning or
electric heat is being used.

{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 Care 10-15
{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
