A/C Button
Push the A/C button to engage the Air Conditioning (A/C). A LED will illuminate when the
A/C system is engaged. The A/C can be deselected manually without disturbing the mode con-
trol selection.
Recirculation Button
Press 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. Recirculation can be used in all modes except for Defrost. Recirculation
may be unavailable 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.
Front Defrost
Use Defrost mode with maximum temperature settings for best windshield and side window
defrosting and defogging. Turn the knob to the Front Defrost position. Air comes from the
windshield and side window demist outlets.
Rear Defrost Button — If Equipped
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 de-
froster is On. The rear window defroster automatically turns OFF after 20 minutes.

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:
•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.
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.
On systems with Manual Climate Controls, if equipped,
the Recirculation mode is not allowed in Defrost mode to
improve window clearing operation. Recirculation is dis-
abled 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.
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 “Fluids and Lubricants” in “Technical Specifications” for
proper coolant selection.
