WARNING
• The air conditioner cooling function op-
erates only when the engine is running.
• Do not leave children or adults who
would normally require the assistance of
others alone in your vehicle. Pets should
also not be left alone. They could acci-
dentally injure themselves or others
through inadvertent operation of the
vehicle. Also, on hot, sunny days, tem-
peratures in a closed vehicle could
quickly become high enough to cause se-
vere or possibly fatal injuries to people or
animals.
• Do not use the recirculation mode for
long periods as it may cause the interior
air to become stale and the windows to
fog up.
Start the engine and operate the controls to
activate the air conditioner.

NOTE:
• Odors from inside and outside the vehiclecan build up in the air conditioner unit.
Odor can enter the passenger compart-
ment through the vents.
• When parking, set the heater and air con- ditioner controls to turn off air recircula-
tion to allow fresh air into the passenger
compartment. This should help reduce
odors inside the vehicle
AUTOMATIC OPERATION
Press the AUTO button to set the automatic
control mode that keeps the air distribution,
temperature and the fan speed automatically.
Cooling and/or dehumidified
heating (AUTO)
This mode may be used all year round as the
system automatically works to keep a con-
stant temperature. Air flow distribution, air
intake control, and fan speed are also con-
trolled automatically.
1. Press the
CLIMATE button on the
lower display menu. The CLIMATE screen
will display on the lower display.
2. Press the AUTO button on. (The indicator on the button will illuminate and AUTO
will be displayed on the CLIMATE screen.) 3. Press the

buttons on the driver’s side to set the de-
sired temperature.
• The temperature of the passenger com- partment will be maintained automatically.
Air flow distribution, air intake control and
fan speed are also controlled automatically.
• A visible mist may be seen coming from the vents in hot, humid conditions as the air is
cooled rapidly. This does not indicate a
malfunction.
Dehumidified defrosting or
defogging
1. Press thefront defroster button on.
(The indicator light on the button will
come on.)
2. Operate the
temperature con-
trol buttons to set the desired
temperature.
• To quickly remove ice from the outside of the windows, use the

trol button or the “” key to set the fan
speed to maximum.
• As soon as possible after the windshield is clean, press the AUTO button to return to
the automatic mode. • When the
front defroster button is
pressed, the air conditioner will automati-
cally be turned on at outside temperatures
approximately 32°F (0°C) to defog the
windshield. The air recirculate mode auto-
matically turns off, allowing outside air to
be drawn into the passenger compartment
to further improve the defogging
performance.
Remote Engine Start with
Intelligent Climate Control (if so
equipped)
Vehicles equipped with automatic climate
controls and Remote Engine Start function
may go into automatic heating or cooling
mode when Remote Engine Start is activated
depending on outside and cabin tempera-
tures. During this period, the climate control
display and buttons will be inoperable until
the ignition switch is turned on. In Remote
Engine Start defrosting mode, the rear win-
dow defroster, heated seat (if so equipped)
and heated steering wheel (if so equipped)
may be activated automatically. In Remote
Engine Start cooling mode, the climate con-
trolled seat (if so equipped) may be activated
automatically.

OPERATING TIPS
The sensors,OAandOBon the instrument
panel, help the system maintain a constant
temperature. Do not put anything on or
around these sensors. • When the engine coolant temperature and
outside air temperature are low, the air may
flow from defroster or foot outlets to ini-
tialize automatic heating mode. This is not a
malfunction. After the coolant temperature
warms up, air will flow normally from the
foot outlets
• A visible mist may be seen coming from the ventilators in hot, humid conditions as the
air is cooled rapidly. This does not indicate a
malfunction.
