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 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 adjust blower speed if
needed.
• If your air conditioning performance seems lower than
expected, check the front of the A/C condenser (lo-
cated in front of the radiator), for an accumulation of
dirt or insects. Clean with a gentle water spray from
behind the radiator and through the condenser. Fabric
front fascia protectors may reduce airflow to the
condenser, reducing air conditioning performance.
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 on the touchscreen 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 prior
settings and the MAX A/C indicator will turn off.
Recirculation Control
When outside air contains smoke, odors, or
high humidity, or if rapid cooling is desired,
you may wish to recirculate interior air by
pressing the RECIRCULATION control button
on the touchscreen or faceplate. Recirculation mode
should only be used temporarily. The recirculation LED
button on the faceplate will illuminate when either
button is selected. Push either button a second time to
turn off the Recirculation mode LED and allow outside
air into the vehicle.
362 UNDERSTANDING YOUR INSTRUMENT PANEL

NOTE: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, the recirculation mode is not allowed
in Defrost mode to improve window clearing operation.
Recirculation will be disabled automatically if this mode
is selected. Attempting to use Recirculation while in this
mode will cause the LED in the control button on the
faceplate to blink and then turn off.
Automatic Temperature Control (ATC)
Automatic Operation
1. Push the AUTO button on the faceplate or press the “AUTO” button on the touchscreen. 2. Adjust the temperature you would like the system to
maintain by adjusting the driver and passenger tem-
perature buttons on the faceplate or buttons on the
touchscreen. Once the desired temperature is dis-
played, 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 temperature. You will
experience 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 Uconnect 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.
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.
364 UNDERSTANDING YOUR INSTRUMENT PANEL

OAT coolant (conforming to MS.90032) is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection. 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
fresh air with the blower setting in high. This will ensureadequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging and Frosting
Vehicle windows tend to fog on the inside of the glass in
mild, rainy and/or humid weather. Windows may frost
on the inside of the glass in very cold 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.
NOTE:
Automatic Temperature Controls (ATC) will au-
tomatically 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, can causeodor, and if they enter the plenum they could plug the
water drains. In winter months, ensure the air intake is
clear of ice, slush and snow.
