CAUTION!
Interior air enters the Rear Automatic Temperature
Control System through an intake grille, located in
floor under the passengers’ seats. 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 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 Temperature 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 func-
tion automatically.
NOTE: It is not necessary to move the temperature. The
system automatically adjusts the temperature, mode and
fan speed to provide comfort as quickly as possible.
Climate Control Functions
A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the operator to
manually activate or deactivate the air conditioning sys-
tem. When the air conditioning system is turned on, cool
dehumidified air will flow through the outlets into the
cabin. For improved fuel economy, press the A/C button to
turn off the air conditioning and manually adjust the
blower and airflow mode settings. Also, make sure to select
only Panel, Bi-Level, or Floor modes.

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 perfor-
mance.
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 front ATC Panel and the
word “AUTO” will illuminate in the front ATC display,
along with two temperatures for the driver and front
passenger. The system will then automatically regulate
the amount of airflow.
2. Adjust the temperature you would like the system to maintain, by adjusting the driver, passenger, and rear
temperatures. Once the desired temperature is dis-
played, the system will achieve and automatically main-
tain that comfort level.

When the Sync feature is active, the rear temperature is
synchronized to the driver ’s temperature setting. If the rear
temperature is changed, the Sync feature will deactivate.
Operating Tips
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. A
solution of 50% OAT (Organic Additive Technology) cool-
ant that meets the requirements of FCA Material Standard
MS.90032 and 50% water is recommended. Refer to “Fluids
and Lubricants” in “Technical Specifications” 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
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 dam-
age when the system is started again.
Window Fogging
Interior fogging on the windshield can be quickly removed
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 window fogging be-
comes objectionable, increase blower speed to improve
airflow and clearing of the side windows. Vehicle windows
tend to fog on the inside in mild but rainy or humid
weather.
NOTE:
•
Recirculate 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.
