The Climate Control System allows you to regulate the temperature, amount, and direction of air circulating throughout the vehicle. The controls are located in the center stack of the instrument panel.

Manual Heating and Air Conditioning System

Single-Zone Manual Climate Control

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 “O” (Off) position.

Temperature Control

Use this control to regulate the temperature of the air inside the passenger compartment. Rotating the knob counterclockwise, from top center into the blue area 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 condenser (located in front of the radiator), for an accumulation 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

Mode control allows you to choose from several selections of air distribution.

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 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.

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 DEFROST mode with maximum blower and 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.Alamp will illuminate when you are in RECIRCULATION 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, DEFROST, or FLOOR mode the RECIRCULATION LED indicator will flash 3 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.

• In order to prevent fogging, when the RECIRCULATION button is pressed and the mode control is set to PANEL, the A/C will engage automatically.

• The A/C can be deselected manually without disturbing the mode control selection.

Economy Mode
If ECONOMY mode is desired, press the A/C button to turn off the indicator light and the A/C compressor.

Rotate the temperature control knob to the desired temperature.

Air Conditioning Operation

Push on this button to engage the Air Conditioning (A/C). A light will illuminate when the A/C System is engaged.

NOTE: The air conditioning compressor will not engage until the engine has been running for about 10 seconds.

Max A/C

For maximum cooling use the A/C and RECIRCULATION mode buttons at the same time.

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 in air-conditioned vehicles must be protected with a high-quality antifreeze coolant to provide proper corrosion protection and to protect against engine overheating. Refer to “Cooling System” under “Maintenance Procedures” and to “Fluids, Lubricants, and Genuine Parts” in “Maintaining Your Vehicle” for information pertaining to the cooling system and coolant selection.

Winter Operation

Use of the air Recirculation mode during Winter months is not recommended because it may cause window fogging.

Vacation Storage

Anytime 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 the fresh air and high blower settings. This will ensure adequate system lubrication to minimize the possibility of compressor damage when the system is started again.

Window Fogging

Interior fogging on the windshield can be quickly removed by turning the mode selector to Defrost. The Defrost/Floor mode can be used to maintain a clear windshield and provide sufficient heating. If side window fogging becomes a problem, increase blower speed.

Vehicle windows tend to fog on the inside in mild but rainy or humid weather.

NOTE: Recirculate without A/C should not be used for long periods as fogging may occur.

Side Window Demisters

A side window demister outlet is located at each end of the instrument panel. These non-adjustable outlets direct air toward the side windows when the system is in the Floor, Mix, or Defrost mode. The air is directed at the area of the windows through which you view the outside mirrors.

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 — If Equipped

The A/C Air Filter will reduce, but not eliminate, diesel and agricultural smells. The filter acts on air coming from outside the vehicle and recirculated air within the passenger compartment. Refer to “Maintenance Procedures” in “Maintaining Your Vehicle” for A/C Air Filter service information or see your authorized dealer for service.

Refer to “Maintenance Schedules” for filter service intervals.
