IconDescription
MAX A/C Setting
Press the button to select MAX A/C. This is the coldest setting and will put the A/C to its maximum power.
A/C Button
Push the A/C button on the touchscreen or faceplate to engage the Air Conditioning (A/C). A LED will illuminate when
the A/C system is engaged.
Recirculation Button
Push and release this button to change the system between recirculation mode and outside air mode. Recirculation can
be used when outside conditions such as smoke, odors, dust, or high humidity are present.
NOTE:
• 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.
• The use of the Recirculation mode in cold or damp weather could cause windows to fog on the inside, because of
moisture buildup inside the vehicle. Select the outside air position for maximum defogging.
• Recirculation can be used in all modes except for Defrost.
• The A/C can be deselected manually without disturbing the mode control selection.
Front Defrost Setting
Push the button to activate Defrost mode. Air comes from the windshield and side window demist outlets. Use De-
frost mode with maximum temperature settings for best windshield and side window defrosting and defogging.
Rear Defrost Button
Push and release the Rear Defrost Control button 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 automati-
cally turns off after ten minutes.

Floor Mode
Floor Mode
Air comes from the floor outlets. A slight amount of air is directed through the defrost and side window demister outlets.
Mix ModeMix Mode
Air is directed through the floor, defrost, and side window demister outlets. This setting works best in cold or snowy con-
ditions that require extra heat to the windshield. This setting is good for maintaining comfort while reducing moisture
on the windshield.
Climate Control OFF Button
Press and release this button on the touchscreen, or push the faceplate button, to turn the Climate Control System off.
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 instru- ments, or abrasive window cleaners on
the interior surface of the window.
CAUTION!
• 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 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:
• If fog or mist appears on the windshield or
side glass, select Defrost mode, and in-
crease 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 ra-
diator), for an accumulation of dirt or in-

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 pro-
vide proper corrosion protection and to pro-
tect against engine overheating. OAT coolant
(conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and de-
froster 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 rec-
ommended, 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 ad-
equate 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.
Cabin Air Filter
The climate control system filters out dust
and pollen from the air. Contact an autho-
rized dealer to service your cabin air filter,
and to have it replaced when needed.
