In Winter, the Climate Control system must be turned on at
least once a month for about 10 minutes.
Have the system inspected at an authorized dealer before the
Summer.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.

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 Mode Mix Mode
Air is directed through the floor, defrost, and side window demister outlets. This setting works best in
cold or snowy conditions that require extra heat to the windshield. This setting is good for
maintaining comfort while reducing moisture on the windshield.
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.

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 orDefrost 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.
Recirculation
In cold weather, use of Recirculation mode may lead to
excessive window fogging. The Recirculation feature may be
unavailable if conditions exist that could create fogging on
the inside of the windshield. The recirculation mode is not
allowed in Defrost mode to improve window clearing oper -
ation. On systems with Manual Climate Controls (if equipped) the
Recirculation mode is not allowed in Defrost mode to
improve window clearing operation. Recirculation is
disabled 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. Organic
Additive Technology (OAT) coolant (conforming to MS.90032)
is recommended. Refer to “Fluids And Lubricants” in “Tech
-
nical Specifications” for proper coolant selection.

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, 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 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. Operating Tips Chart
