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.
On systems with Manual Climate Controls, if equipped, the
Recirculation mode is not allowed in Defrost mode to
improve window clearing operation. Recirculation is
disabled automatically if this mode is selected. Attempting
to use Recirculation while in this mode causes the LED in
the control button to blink and then turns off.

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 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 temperature settings for
cold or hot vehicles. The system automatically adjusts
the temperature, 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 U.S./Metric customer-program-
mable feature. Refer to the "Uconnect Settings" in
"Multimedia" for further information.
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.

NOTE:
Refer to the chart at the end of this section for suggested
control settings for various weather conditions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended.

GETTING TO KNOW YOUR VEHICLE
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
Recirculation 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.
