Climate controls
The Climate Control System allows you to regulate the temperature, amount, and direction of air circulating throughout the vehicle. The controls are located on the instrument panel below the radio.
NOTE: During snowplow usage on vehicles equipped with outside temperature display, the display may show higher temperatures than the outside ambient tempera- ture. The higher displayed temperature is due to blocked or reduced airflow to the underhood ambient tempera- ture sensor caused by the snowplow. In addition, on vehicles equipped with Automatic Temperature Control (ATC), it is suggested that the interior cabin temperature be manually controlled should the system not perform as desired while in automatic mode. Both the outside tem- perature display and ATC operation will return to nor- mal when the snowplow is removed.
Manual Heating And Air Conditioning System
The controls for the manual heating and air conditioning system in this vehicle consist of a series of outer rotary
dials and inner push knobs. These comfort controls can be set to obtain desired interior conditions.
1 – Front Blower 4 – DEFROST Mode 2 – Temperature Control 5 – Air Conditioning (A/C) 3 – MODE Control 6 – RECIRCULATION Control
Front Blower Control
There are four blower speeds. Use this control to regulate the amount of air forced through the system in any mode you select. The blower speed increases as you move the control clockwise from the OFF position.
NOTE: For vehicles equipped with Remote Start, the climate controls will not function during Remote Start operation if the blower control is left in the OFF position.
Temperature Control
Use this control to regulate the tem- perature of the air inside the passenger compartment. Rotating the knob coun- terclockwise, from top center into the blue area of the scale, indicates cooler
temperatures. Rotating the knob clockwise, into the red area, indicates warmer temperatures.
NOTE: If your air conditioning performance seems lower than expected, check the front of the A/C con- denser (located in front of the radiator), for an accumu- lation of dirt or insects. Clean with a gentle water spray from behind the radiator and through the condenser. Fabric front fascia protectors may reduce airflow to the condenser, reducing air conditioning performance.
Mode Control (Air Direction)
Mode control allows you to choose from several patterns of air distribu- tion. You can select either a primary mode, as identified by the symbols, or a blend of two of these modes. The closer the control is to a particular mode, the more air distribution you
receive from that mode.
Panel Mode
Air is directed through the outlets in the instrument panel. These outlets can be adjusted to direct airflow.
Bi-Level Mode
Air is directed through the panel and floor outlets.
NOTE: There is a difference in temperature (in any conditions other than full cold or full hot), between the upper and lower outlets for added comfort. The warmer air goes to the floor outlets. This feature gives improved comfort during sunny but cool conditions.
Floor Mode
Air is directed through the floor outlets with a small amount through the defrost and side window
demist outlets.
Mix Mode
Air is directed through the floor, defrost and side window demist outlets. This setting works best in cold or snowy conditions that require extra heat at
the windshield. This setting is good for maintaining comfort, while reducing moisture on the windshield.
Defrost Mode
Air is directed through the windshield and side window demist outlets. Use the DEFROST mode
with maximum blower and warm temperature settings for best windshield and side window defrosting.
NOTE: The air conditioning compressor operates in MIX and DEFROST, or a blend of these modes even if the A/C button is not pressed. This dehumidifies the air to help dry the windshield. To improve fuel economy, use these modes only when necessary.
Recirculation Control
Press this button to choose between outside air intake or recirculation of the air inside the vehicle. A LED will illuminate when you are in Recircula- tion mode. Only use the Recirculation mode to temporarily block out any outside odors, smoke, or dust, and to
cool the interior rapidly upon initial start-up in very hot or humid weather.
NOTE:
If the RECIRCULATION button is pressed when the
system is in Mix or Defrost mode the Recirculation LED indicator will flash three times and then turn off to indicate Recirculation mode is not allowed.
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.
In cold or damp weather, the use of the Recirculation mode will cause windows to fog on the inside because of moisture buildup inside the vehicle. For maximum defogging, select the outside air position.
The A/C can be deselected manually without disturb- ing the mode control selection by pressing the A/C button.
Air Outlets
The airflow from each of the instrument panel outlets can be adjusted for direction, and turned on or off to control airflow.
NOTE: For maximum airflow to the rear, the center instrument panel outlets can be directed toward the rear seat passengers.
Economy Mode
If ECONOMY mode is desired, press the A/C button to turn off the LED indicator and the A/C compressor. Rotate the temperature control knob to the desired temperature.
Air Conditioning Operation
Push this button to engage the Air Conditioning (A/C). A LED will illu- minate when the A/C system is engaged.
MAX A/C
For maximum cooling, when MAX A/C is selected the A/C is turned on automatically and the air is recircu- lated.
NOTE: A/C cannot be deselected when in MAX A/C position. The LED will blink three times if the A/C button is pushed.
Automatic Temperature Control (ATC) If Equipped
The Automatic Temperature Control (ATC) allows
both driver and front passenger seat occupants to select individual comfort settings.
When occupants in the vehicle select an Auto mode operation, Auto blower operation is set by using rotary knobs on the control unit and a comfort temperature setting by using the temperature up and down but- tons.
The system provides set-and-forget operation for op- timum comfort and convenience.
The system can be controlled manually, if desired. • SYNC feature links the temperature controls, the passenger side temperature becomes the same as the temperature selected by the driver.
The ATC system automatically maintains the interior comfort level desired by the driver and all passengers.

Automatic Operation
1. Position the MODE control knob to the Auto position on the Automatic Temperature Control (ATC) Panel. 2. Position the BLOWER control knob in the Auto posi- tion on the ATC Panel. 3. Next, adjust the temperature you would like the system to maintain by adjusting the driver and front passenger temperature buttons. Once the desired tem- perature is displayed, the system will achieve and auto- matically maintain that comfort level. 4. When the system is set up for your comfort level, it is not necessary to change the settings. You will 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 fan speed to provide comfort as quickly as possible.
The temperature can be displayed in U.S. or Metric units by selecting the US/M customer-programmable feature. Refer to the “Electronic Vehicle Information Center (EVIC) Customer-Programmable Features (SETUP)” in this section of the manual.
To provide you with maximum comfort in the Automatic mode, during cold start-ups the blower fan will remain on low and the DELAY symbol will appear in the ATC display until the engine warms up. The blower will increase in speed and transition into Auto mode and DELAY will no longer be illuminated in the display. The blower will engage immediately if the Defrost mode is selected, or by adjusting the blower control knob and setting the fan to any fixed speed.
Manual Operation
This system offers a full complement of manual override features.
NOTE: Each of these features operate independently from each other. If any one feature is controlled manually, the temperature doors will continue to operate automati- cally.
There are six fixed blower speeds. Use this control to regulate the amount of air forced through the system in any mode you select. The blower speed increases as you move the control clockwise from the OFF position.
The blower fan speed can be set to any fixed speed by adjusting the blower control knob. The fan will now operate at a fixed speed until additional speeds are
selected. This allows the front occupants to control the volume of air circulated in the vehicle and cancel the Auto mode. The operator can also select the direction of the airflow by selecting one of the following positions.
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 rotated to regulate or shut off the airflow from these outlets.
Bi-Level Mode
Air comes from the instrument panel outlets, floor outlets and defrost outlets.
NOTE: In many temperature positions, the BI-LEVEL mode is designed to provide cooler air out of the panel outlets and warmer air from the floor outlets.
Blower Control
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
Air comes from the floor, defrost and side window demist outlets. This mode works best in cold or snowy conditions. It allows you to stay comfortable
while keeping the windshield clear.
Defrost Mode
Air comes from the windshield and side window demist outlets. Use Defrost mode with maximum
blower and temperature settings for best windshield and side window defrosting.
NOTE: While operating in the other modes, the system will not automatically sense the presence of fog, mist or ice on the windshield. Defrost mode must be manually selected to clear the windshield and side glass.
The Air Conditioning (A/C) button allows the operator to manually activate or deactivate the air conditioning system. When in A/C mode and the
ATC is set to a cool temperature, dehumidified air flows through the air outlets. If Economy mode is desired, press the A/C button to turn off the A/C mode in the ATC display and deactivate the A/C system.
NOTE:
If the system is in Mix, Bi-Level 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.
Recirculation Control
When outside air contains smoke, odors, or high humidity, or if rapid cooling is desired, you may wish to recirculate interior air by pressing the RECIRCULATION control button.
Recirculation mode should only be used temporarily. The recirculation LED will illuminate on the blower control knob when this button is selected. Push the button a second time to turn off the Recirculation mode LED and allow outside air into the vehicle.
NOTE: In cold weather, use of Recirculation mode may lead to excessive window fogging. The Recirculation mode is not allowed in the Floor/Defrost Mix and Defrost modes to improve window clearing operation. Recirculation will be disabled automatically if these modes are selected.
Summer Operation
The engine cooling system in air conditioned vehicles must be protected with a high-quality antifreeze coolant to provide proper corrosion protection and to protect against engine overheating. A solution of 50% ethylene glycol antifreeze coolant and 50% water is recommended. Refer to “Maintenance Procedures” in “Maintaining Your Vehicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor- mance, make sure the engine cooling system is function- ing properly and the proper amount, type, and concen- tration of coolant is used. Refer to “Maintenance Procedures” in “Maintaining Your Vehicle” for proper coolant selection. Use of the air Recirculation mode during Winter months is not recommended because it may cause window fogging.
Vacation/Storage
Any time 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 in high. This will ensure adequate system lubrication to minimize the possibility of compressor damage when the system is started again.
Window Fogging and Frosting
Vehicle windows tend to fog on the inside of the glass in mild, rainy and/or humid weather. Windows may frost on the inside of the glass in very cold 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 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.
