8-4 Climate Controls
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 5‑53
for more information on the
Auto Defog selection. The air
conditioning may also run
if
0is selected.
ECO Mode: The vehicle 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 vehicle 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.

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.
For vehicles 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 2‑16. Notice:
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
wouldn't be covered by the
vehicle warranty.
Remote Start: For vehicles 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 L (Low) in heavy stop‐and‐go
traffic or when traveling downhill.
L (Low) requires less brake
pedal application 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.
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 Charging/Maintenance
Charging
Keep the vehicle plugged in, even
when fully charged, to keep the
battery temperature ready for the
next drive. This is important when
outside temperatures are extremely
hot or cold.

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.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
The high voltage battery
coolant reservoir is located
on the passenger side of the
engine compartment. SeeEngine
Compartment Overview on
page 10‑10 for more information
on location.Check to see if coolant is visible
in the high voltage battery coolant
reservoir. If coolant is visible but the
coolant level is below the cold fill
line, there could be a leak in the
cooling system.
The high voltage battery coolant
should only be serviced by a
qualified technician.
