Blower Control
There are seven blower speeds. Use this control knob to regulate the amount of air forced through the
system in any mode you select. The blower speed increases as you move the control clockwise from
the off position.
Modes Control
Rotate the Mode Control Knob to change the airflow distribution mode. The airflow distribution mode
can be adjusted so air comes from the instrument panel outlets, floor outlets, defrost outlets and
demist outlets. The Mode settings are as follows:
Panel Mode Panel Mode
Air comes from the outlets in the instrument panel. Each of these outlets can be individually adjusted
to direct the flow of air. The air vanes of the center outlets and outboard outlets can be moved up and
down or side to side to regulate airflow direction. There is a shut off wheel located below the air vanes
to shut off or adjust the amount of airflow from these outlets.
Bi-Level Mode Bi-Level Mode
Air comes from the instrument panel outlets and floor outlets. A slight amount of air is directed
through the defrost and side window demister outlets.
NOTE:
Bi-Level mode is designed under comfort conditions to provide cooler air out of the panel outlets and
warmer air from the floor outlets.

Recirculation can be used when outside conditions such as smoke, odors, dust, or high humidity are
present. Recirculation can be used in all modes. Recirculation may be unavailable (button on the
touchscreen greyed out) if conditions exist that could create fogging on the inside of the windshield.
The A/C can be deselected manually without disturbing the mode control selection. Continuous use
of the Recirculation mode may make the inside air stuffy and window fogging may occur. Extended
use of this mode is not recommended.

NOTE:
• On vehicles equipped with a 12-inch display, reducing theblower control all the way down will turn the climate off.
• 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 radi -
ator 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 condi
-
tions 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 you would like the system to maintain by adjusting the driver and passenger
temperature control buttons. Once the desired tempera -
ture is displayed, the system will achieve and automati -
cally 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 func -
tion automatically.

NOTE:
• It is not necessary to move the temperature settings forcold 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 perfor
-
mance, 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 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 wind
-
shield, is free of obstructions, 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.
Cabin Air Filter
The climate control system filters out dust and pollen from
the air. Contact an authorized dealer to service your cabin air
filter, and to have it replaced when needed.
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.
