Climate Control Functions
A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the
operator to manually activate or deactivate
the air conditioning system. When the air
conditioning system is turned on, cool dehu-
midified air will flow through the outlets into
the cabin. For improved fuel economy, press

NOTE:
For Manual Climate Controls, if the system
is in Mix, Floor or Defrost Mode, the A/C
can be turned off, but the A/C system shall
remain active to prevent fogging of the
windows.
If fog or mist appears on the windshield or
side glass, select Defrost mode, and
increase blower speed if needed.

If your air conditioning performance seems
lower than expected, check the front of the A/C
condenser (located in front of the radiator), for
an accumulation of dirt or insects. Clean with a
gentle water spray from the front of the radiator
and through the condenser.
MAX A/C
MAX A/C sets the control for maximum
cooling performance.

Press and release to toggle between MAX A/C
and the prior settings. The button illuminates
when MAX A/C is on.
In MAX A/C, the blower level and mode position
can be adjusted to desired user settings.
Pressing other settings will cause the MAX A/C
operation to switch to the selected setting and
MAX A/C to exit.

Recirculation
In cold weather, use of Recirculation mode
may lead to excessive window fogging. The
Recirculation feature may be unavailable
(button on the touchscreen greyed out) if
conditions exist that could create fogging on
the inside of the windshield.
Automatic Temperature Control (ATC)
Automatic Operation
1. Push the AUTO button on the faceplate,
or the AUTO button on the touchscreen
on the Automatic Temperature Control
(ATC) Panel.
2. Next, adjust the temperature that you would like the system to maintain by
adjusting the driver and passenger
temperature control buttons. Once the
desired temperature is displayed, the
system will achieve and automatically
maintain that comfort level.
3. When the system is set up for your comfort level, it is not necessary to
change the settings. You will experience
the greatest efficiency by simply allowing
the system to function automatically.
NOTE:
It is not necessary to move the tempera-
ture settings for cold or hot vehicles. The
system automatically adjusts the tempera-
ture, mode, and blower speed to provide
comfort as quickly as possible.

The temperature can be displayed in U.S.
or Metric units by selecting the US/Metric
customer-programmable feature. Refer to
the “Uconnect Settings” in “Multimedia”
in your Owner’s Manual for further infor-
mation.
To provide you with maximum comfort in the
Automatic mode during cold start-ups, the
blower fan will remain on low until the
engine warms up. The blower will increase in
speed and transition into Auto mode.
Manual Operation Override
This system offers a full complement of
manual override features. The AUTO symbol
in the front ATC display will be turned off
when the system is being used in the manual
mode.
Operating Tips
NOTE:
For suggested control settings for various
weather conditions, refer to “Climate
Controls” in “Getting To Know Your Vehicle”
in the Owner’s Manual.
Summer Operation
The engine cooling system must be
protected with a high-quality antifreeze
coolant to provide proper corrosion protec -
tion and to protect against engine over -
heating. OAT coolant (conforming to
MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and
defroster performance, make sure the engine
cooling system is functioning properly and
the proper amount, type, and concentration
of coolant is used. Use of the Air Recircula -
tion mode during Winter months is not
recommended, because it may cause window
fogging.
Vacation/Storage
Before you store your vehicle, or keep it out
of service (i.e., vacation) for two weeks or
more, run the air conditioning system at idle
for about five minutes, in fresh air with the
blower setting on high. This will ensure
adequate system lubrication to minimize the
possibility of compressor damage when the
system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in
mild, rainy, and/or humid weather. To clear
the windows, select Defrost or Mix mode and
increase the front blower speed. Do not use
the Recirculation mode without A/C for long
periods, as fogging may occur.
CAUTION!
Failure to follow these cautions can cause
damage to the heating elements:
Use care when washing the inside of the
rear window. Do not use abrasive window
cleaners on the interior surface of the
window. Use a soft cloth and a mild
washing solution, wiping parallel to the
heating elements. Labels can be peeled
off after soaking with warm water.
Do not use scrapers, sharp instruments,
or abrasive window cleaners on the inte-
rior surface of the window.
Keep all objects a safe distance from the
window.

Outside Air Intake
Make sure the air intake, located directly in
front of the windshield, is free of obstruc-
tions, such as leaves. Leaves collected in the
air intake may reduce airflow, and if they
enter the plenum, they could plug the water
drains. In Winter months, make sure the air
intake is clear of ice, slush, and snow.
Cabin Air Filter
The climate control system filters out dust
and pollen from the air. Contact an autho -
rized dealer to service your cabin air filter,
and to have it replaced when needed.
Stop/Start System — If Equipped
While in an Autostop, the Climate Control
system may automatically adjust airflow to
maintain cabin comfort. Customer settings
will be maintained upon return to an engine
running condition.
Windshield Wiper De-icer — If Equipped
The windshield wiper de-icer is a heating
element located at the base of the wind -
shield.
It operates automatically once the following
conditions are met:
Activation By Front Defrost
The wiper de-icer activates automatically
during a cold weather manual start with
full defrost, and when the ambient tem-
perature is below 33°F (0.6°C) .
Activation By Rear Defrost
The wiper de-icer activates automatically
when the Rear Defrost is operating and
the ambient temperature is below 33°F
(0.6°C) .
Activation By Remote Start Operation
When the Remote Start is activated and
the outside ambient temperature is less
than 33°F (0.6°C) the windshield wiper
de-icer is activated. Upon exiting Remote
Start, the climate control functions will
resume their previous operation except, if
the de-icer is active, the de-icer timer
and operation will continue.
