NOTE:In cold weather, use of Recirculation mode may
lead to excessive window fogging. The Recirculation
mode is not allowed in Defrost mode to improve window
clearing operation. Recirculation will be disabled auto-
matically if this mode is selected. Attempting to use
Recirculation while in this mode will cause the LED on
the faceplate to blink and then turn off and the button on
the touchscreen to be greyed out.
Automatic Temperature Control (ATC)
Automatic Operation
1. Press the AUTO button on the faceplate or button on
the touchscreen button (4) on the Automatic Tempera-
ture Control (ATC) Panel.
2. Next, adjust the temperature you would like the
system to maintain by adjusting the driver and pas-
senger temperature buttons on the touchscreen or
buttons on the faceplate. Once the desired temperature
is displayed, the system will achieve and automati-
cally 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 experi-
ence the greatest efficiency by simply allowing the
system to function automatically.
NOTE:
•It is not necessary to move the temperature settings.
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 US/M customer-programmable
feature. Refer to the “Uconnect® System Settings” in
this section of the manual.

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
The system allows for manual selection of blower speed,
air distribution mode, A/C status and recirculation con-
trol.
The blower fan speed can be set to any fixed speed by
adjusting the blower control. The fan will now operate at
a fixed speed until additional speeds are selected. This
allows the front occupants to control the volume of air
circulated in the vehicle and cancel the Auto mode.
The operator can also select the direction of the airflow
by selecting one of the available mode settings. A/C
operation and Recirculation control can also be manually
selected in Manual operation.
NOTE:Each of these features operates independently
from each other. If any feature is controlled manually,
temperature control will continue to operate automati-
cally.
Rear Automatic Temperature Control (ATC) — If
Equipped
The rear ATC system has floor air outlets at the rear right
side of the 3rd Row seats and overhead outlets at each
outboard rear seating position. The system provides
heated air through the floor outlets or cool, dehumidified
air through the headliner outlets.
The rear system temperature control buttons are located
in the Uconnect® press system, located on the instrument
panel.

Controlling The Rear Climate Controls From The
Front ATC Panel
The Three-Zone ATC system allows for adjustment of the
rear climate controls from the front ATC panel.
To change the rear system settings:
•Press#REAR#button to change control to rear control
mode, Rear display (below) will appear. Control func-
tions now operate rear system.
•To return to Front screen, press#REAR#button again,
or it will revert to the Front screen after six seconds.
Rear Lock
Pressing the Rear Temperature Lock button on the
Uconnect® touchscreen, illuminates a lock symbol in the
rear display. The rear temperature and air source are
controlled from the front Uconnect® system.
Rear second row occupants can only adjust the rear ATC
control when the Rear Temperature Lock button is turned
off.
The rear ATC is located in the headliner, near the center
of the vehicle.
•Press the Rear Temperature Lock button on the
Uconnect® touchscreen. This turns off the Rear Tem-
perature Lock icon in the rear temperature knob.
•Rotate the Rear Blower, Rear Temperature and the
Rear Mode Control knobs to suit your comfort needs.
•ATC is selected by adjusting the rear blower knob
counterclockwise to AUTO.
Once the desired temperature is displayed, the ATC
System will automatically achieve and maintain that
comfort level. 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 automati-
cally adjusts the temperature, mode and fan speed to
provide comfort as quickly as possible.
Rear Blower Control
The rear blower control knob can be manually set to off,
or any fixed blower speed, by rotating the knob from low

to high. This allows the rear seat occupants to control the
volume of air circulated in the rear of the vehicle.
CAUTION!
Interior air enters the Rear Automatic Temperature
Control System through an intake grille, located in
the right side trim panel behind the third row seats.
The rear outlets are located in the right side trim
panel of the 3rd Row seat. Do not block or place
objects directly in front of the inlet grille or heater
outlets. The electrical system could overload causing
damage to the blower motor.
Rear Temperature Control
To change the temperature in the rear of the vehicle,
rotate the temperature knob counterclockwise to lower
the temperature, and clockwise to increase the tempera-
ture. The rear temperature settings are displayed in the
Uconnect® system.
When rear controls are locked by the Uconnect® system,
the Rear Temperature Lock symbol on the temperature
knob is illuminated and any rear overhead adjustments
are ignored.
Rear Mode Control
Auto Mode
•The rear system automatically maintains the correct
mode and comfort level desired by the rear seat
occupants.
Headliner Mode
Air comes from the outlets in the headliner. Each
of these outlets can be individually adjusted to
direct the flow of air. Moving the air vanes of the outlets
to one side will shut off the airflow.

Bi-Level Mode
Air comes from both the headliner outlets and the
floor outlets.
NOTE:In many temperature positions, the BI-LEVEL
mode is designed to provide cooler air out of the head-
liner outlets and warmer air from the floor outlets.
Floor Mode
Air comes from the floor outlets.
Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
A solution of 50% OAT (Organic Additive Technology)
coolant that meets the requirements of Chrysler Material
Standard MS-12106 and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
Use of the air Recirculation mode during winter months
is not recommended because it may cause window
fogging.
Vacation Storage
Any time 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 the
fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.

Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes a problem, increase the blower
speed. Vehicle windows tend to fog on the inside in mild
but rainy or humid weather.
NOTE:
•Recirculation mode without A/C should not be used
for long periods, as fogging may occur.
•Automatic Temperature Controls (ATC) will automati-
cally adjust the climate control settings to reduce or
eliminate window fogging on the front windshield.
When this occurs, recirculation will be unavailable.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions 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.
A/C Air Filter
The climate control system filters outside air containing
dust, pollen and some odors. Strong odors cannot be
totally filtered out. Refer to “Maintenance Procedures” in
“Maintaining Your Vehicle” for filter replacement instruc-
tions.
