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)
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.
54 GETTING TO KNOW YOUR VEHICLE

3. When the system is set up for your comfort level, it isnot 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.
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 adequate system
lubrication to minimize the possibility of compressor dam-
age 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 De-
frost 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.
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.

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, 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.
A/C Air Filter
The climate control system filters out dust and pollen from
the air. Contact an authorized dealer to service your A/C
air filter, and to have it replaced when needed.

WINDOWS
Power Window Controls
The power window controls are located on the shifter
bezel, below the climate controls, which operate the driver
and passenger door windows. The window controls will
operate when the ignition switch is in the MAR (ACC/
ON/RUN) position.
WARNING!
Never leave children unattended in a vehicle, and do
not let children play with power windows. Do not
leave the key fob in or near the vehicle, or in a location
accessible to children. Occupants, particularly unat-
tended children, can become entrapped by the win-
dows while operating the power window switches.
Such entrapment may result in serious injury or death.
Auto-Down
The window switches have an Auto-Down feature. Push
the window switch for approximately one second, release,
and the window will go down automatically. To cancel the
Auto-Down movement, operate the switch in either the up
or down direction and release the switch. To open the
window part way, pull the window switch briefly, and
release the switch when the window is in the desired
position.
Wind Buffeting
Wind buffeting can be described as the perception of
pressure on the ears or a helicopter-type sound in the ears.
Your vehicle may exhibit wind buffeting with the windows
down, or the sunroof (if equipped) in certain open or
Power Window Switches
