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-programmable 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.
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.

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. Organic Additive Technology (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 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 (A/C) 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.
