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.

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, push 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 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.
Automatic Temperature Control (ATC) —
If Equipped
Automatic Operation
1. Push the AUTO button on the faceplate.
2. Next, adjust the temperature you would like the system
to maintain by adjusting the temperature control but-
tons. Once the desired temperature is displayed, the
system achieves and automatically maintains that com-
fort level. 3GETTING TO KNOW YOUR VEHICLE 53

3. When the system is set up for your comfort level, it is
not necessary to change the settings. You 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 remains on low
until the engine warms up. The blower increases 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.
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.54 GETTING TO KNOW YOUR VEHICLE
