Front Defrost Button
Press and release the touchscreen button, or push and release the button on the faceplate, to
change the current airflow setting to Defrost mode. The indicator illuminates when this feature
is on. Air comes from the windshield and side window demist outlets. When the defrost button
is selected, the blower level will increase. Use Defrost mode with maximum temperature set-
tings for best windshield and side window defrosting and defogging. Performing this function
will cause the ATC to switch into manual mode. If the front defrost mode is turned off, the cli-
mate system will return the previous setting.
Rear Defrost Button
Push and release the button on the touchscreen, or push and release the button on the faceplate,
to turn on the rear window defroster and the heated outside mirrors (if equipped). An indicator
will illuminate when the rear window defroster is on. The rear window defroster automatically
turns off after 10 minutes.

Blower Control
Blower Control is used to regulate the amount of air forced through the climate system. There
are seven blower speeds available. Adjusting the blower will cause automatic mode to switch to
manual operation. The speeds can be selected using either the blower control knob on the face-
plate or the buttons on the touchscreen.
• Faceplate: The blower speed increases as you turn the blower control knob clockwise from
the lowest blower setting. The blower speed decreases as you turn the blower control knob
counterclockwise.
• Touchscreen: Use the small blower icon to reduce the blower setting and the large blower
icon to increase the blower setting. Blower can also be selected by pressing the blower bar
area between the icons.
Panel ModePanel 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 lo-
cated 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.

CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
•Use care when washing the inside of the rear win-
dow. 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 heat-
ing 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.
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:
•
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.
Recirculation
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.
The recirculation indicator will illuminate when this button
is selected. Press the button a second time to turn off the
Recirculation mode and allow outside air into the vehicle.
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 to blink and then turn off.
Automatic Temperature Control (ATC) —
If Equipped
Automatic Operation
1. Push the AUTO button on the faceplate, or the AUTObutton on the touchscreen on the Automatic Tempera-
ture 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
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 US/Metric customer-programmable fea-
ture.
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.
NOTE: The system will not automatically sense the pres-
ence of fog, mist or ice on the windshield. DEFROST mode
must be manually selected to clear the windshield and side
glass.

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. Refer
to “Maintenance Procedures” in “Maintaining Your Ve-
hicle” for proper coolant selection.
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. Refer to “Maintenance Procedure” 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 condi-
tioning system at idle for about five minutes in fresh air
with the blower setting in high. This will ensure adequate
system lubrication to minimize the possibility of compres-
sor damage when the system is started again.
Window Fogging
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 auto-
matically 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 cause
odor, 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 has a cabin air filter that filters
out dust and pollen from the air. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for filter re-
placement instructions.
