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
conditioning system is turned on, cool dehu-
midified 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 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
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) —
If Equipped
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 that 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 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 tempera-
ture settings for cold or hot vehicles. The
system automatically adjusts the tempera-
ture, 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” in the Owner’s Manual 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
Summer Operation
The engine cooling system must be
protected with a high-quality antifreeze
coolant to provide proper corrosion protec -
tion and to protect against engine over -
heating. 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 Recircula -
tion 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 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.
Outside Air Intake
Make sure the air intake, located directly in
front of the windshield, is free of obstruc -
tions, 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.
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 inte-
rior surface of the window.
Keep all objects a safe distance from the
window.

Gear Shift Indicator (GSI) — If Equipped
The Gear Shift Indicator (GSI) system is
enabled on vehicles when automatic trans-
mission is in manual shift mode. The GSI
provides the driver with a visual indication
when the recommended gear shift point has
been reached. This indication notifies the
driver that changing gears will allow a reduc -
tion in fuel consumption. When the up shift
indicator is shown on the instrument cluster
display, the GSI is advising the driver to
engage a higher gear. When the down shift
indicator is shown on the display, the GSI is
advising the driver to engage a lower gear.
The GSI remains illuminated until the driver
changes gear, or the driving conditions
return to a situation where changing gears is
not required to improve fuel consumption.

Diesel Particulate Filter (DPF) Messages
This engine meets all required diesel engine
emissions standards. To achieve these emis -
sions standards, your vehicle is equipped
with a state-of-the-art engine and exhaust
system. These systems are seamlessly inte -
grated into your vehicle and managed by the
Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the
exhaust system’s catalyst to trap and burn
Particulate Matter (PM) pollutants, with no
input or interaction on your part.
WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do
not park or operate your vehicle in areas
where your exhaust system can contact
anything that can burn.
CAUTION!
Always drive at a speed appropriate to the
traffic conditions, the weather and traffic
regulations. The engine may be switched
off even if the warning light is on: repeated
interruptions of the regeneration process
could cause an early deterioration of
engine oil. For this reason it is always
advisable to wait for the symbol to go off
before turning off the engine, following the
instructions above. Do not complete the
DPF regeneration process when the vehicle
is stopped.
