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 accumula-
tion 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
performance.
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 set-
tings 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.
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. Attempt-
ing to use Recirculation while in this mode causes the
LED in the control button to blink and then turns off.
AUTOMATIC TEMPERATURE
CONTROL (ATC)
Automatic Operation
1. Push the AUTO button on the faceplate, or the AUTO
button on the touchscreen on the Automatic Tem-
perature Control (ATC) Panel.
2. Next, adjust the temperature you would like the sys-
tem to maintain by adjusting the driver and passen-
ger 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 Set-
tings” 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 over-
ride features. The AUTO symbol in the front ATC display
will be turned off when the system is being used in the
manual mode.
OPERATING TIPS
NOTE:
Refer to the chart at the end of this section for sug-
gested control settings for various weather conditions.
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 overheat-
ing. OAT coolant (conforming to MS.90032) is
recommended.
