For best results, clear all snow and
ice from the windshield before
defrosting.
L:Touch to turn on
recirculation.
An indicator light comes on. Air is
recirculated to quickly cool the
inside of the vehicle or to reduce the
entry of outside air and odors. Using
the recirculation mode for extended
periods may cause the windows to
fog. If this happens, select the
defrost mode.
Using air conditioning and
recirculation together for long
periods of time may cause the air
inside the vehicle to become too
dry. To prevent this from happening,
after the air in the vehicle has
cooled, turn the recirculation
mode off.
Touching this button cancels
automatic recirculation. Press AUTO
to return to automatic operation;
recirculation runs automatically as
needed.
vHEAT : Touch to turn the heater
on when the fan is on. A/C :
Touch to turn the air
conditioning on when the fan is on.
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 0146.
Auto Heated Seats : If equipped,
when the vehicle is on, this feature
will automatically activate the
heated seats at the level required by
the vehicle’ s interior temperature. In
auto mode, the indicators
automatically show the level setting
required.
Use the manual heated seat buttons
on the infotainment display to turn
auto heated seats off. Once this feature is turned off, the auto heated
seats will be activated the next time
the vehicle is turned on.
In manual mode, the controls can
be accessed while the vehicle is on
by touching
(orMwith three level
indicators high, medium, low or off
on the climate control display. If the
passenger seat is unoccupied, the
auto heated seats feature will not
activate that seat.
See Heated Front Seats 060 and
Vehicle Personalization 0146.
Rear Window Defogger
K:Press to turn the rear window
defogger on or off. An indicator light
on the button comes on to show that
the rear window defogger is on.
The defogger only works when the
vehicle is on. The defogger will turn
off if the vehicle is turned off.

It is not necessary to regularly
check coolant unless a leak is
suspected or an unusual noise is
heard. A coolant loss could indicate
a problem. Have it inspected and
repaired by your dealer.
The following explains the cooling
systems and how to check coolant
levels.

High Voltage Battery
. Single Power Inverter Module
(SPIM), Accessory Power
Module (APM), and Charger
Module
. Cabin Heating
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 outside the
battery on a cradle, heats the
coolant until the correct temperature
is reached.
Single Power Inverter Module
(SPIM), Accessory Power
Module (APM), and Charger
Module
The SPIM, APM, and charger
module are cooled using a separate
coolant loop. These modules are
kept below a maximum temperature.
If the temperature rises above this
temperature, the electric cooling fan
will turn on to cool the coolant.
Cabin Heating
Cabin heating is maintained by
coolant heated by the Coolant
Heater Control Module (CHCM),
separate from the power electronics
and battery coolant loops. This
module heats the coolant based on
temperature inputs from the cabin
climate control systems.
