Climate Control Functions
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 condi -
tioning 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 manu -
ally 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 radi -
ator), 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
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 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 Recircu -
lation 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. Attempting 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 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 auto -
matically 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.

20_DJD2_OM_EN_USC_t.book Page 68

GETTING TO KNOW YOUR VEHICLE69
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.
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. 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 recom -
mended, 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 lubri -cation 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.
CAUTION!
Failure to follow these cautions can cause
damage to the heating elements:
Use care when washing the inside of the
rear window. Do not use abrasive window
cleaners on the interior surface of the
window. Use a soft cloth and a mild
washing solution, wiping parallel to the
heating elements. Labels can be peeled off
after soaking with warm water.
Do not use scrapers, sharp instruments, or
abrasive window cleaners on the interior
surface of the window.
Keep all objects a safe distance from the
window.
