ELECTRONIC AUTOMATIC TEMPERATURE CONTROL (EATC) SYSTEM

The EATC system will maintain a selected temperature and automatically control the fan speed and airflow location.

Automatic operation

Press Automatic/AUTO and select the desired temperature. The system will either heat or cool to achieve the selected temperature. The system will automatically determine fan speed, airflow location and if outside air or recirculated air is required. When in automatic operation and weather conditions require heat, the air will be sent to the floor ducts. However, until the engine warmed, the fan speed will operate at a low speed and airflow will be directed to the windshield defroster ducts. Upon engine warm up, the system will automatically direct airflow to the floor ducts and operate the required fan speed to achieve the selected temperature. If unusual conditions exist (i.e.-window fogging, etc.), the manual overrides allow you to select airflow locations and the fan speed. To return to automatic operation, press Automatic/AUTO.

Temperature selection

To control the temperature, select the desired temperature by pressing the temperature controls. For continuous maximum cooling, push the temperature control until 16°C (60°F) is shown in the display window. The system will continue maximum cooling (disregarding the displayed temperature) until a warmer temperature is selected by pressing the temperature control. For continuous maximum heating, push the temperature control until 32°C (90°F) appears in the display window. The system will continue maximum heating (disregarding the displayed temperature) until a cooler temperature is selected by pressing the temperature control.

Temperature conversion

Press the Max A/C and Defrost simultaneously for one second to switch between Fahrenheit and Celsius. The English/Metric (E/M) control on the message center (if equipped) and the trip computer will not change the temperature display.

Displaying outside temperature

Press Ext Temp/Outside Temp to display the outside temperature. The outside temperature will be displayed until Ext Temp/Outside Temp has been pressed again.

If the interior temperature or fan speed are adjusted or a manual override is selected while the outside temperature is being displayed, the new temperature, fan speed, or override control will appear in the display window for four seconds and the outside temperature will return to the display window.

The outside temperature reading is most accurate when the vehicle is moving. Higher readings may be displayed when the vehicle is not moving. Due to locations, the outside temperature readings displayed on the climate control system may not agree with those from the radio station broadcasts.

Fan speed

When in automatic operation, fan speed operates as necessary to achieve the selected temperature. If desired, the fan speed can be controlled manually through the use of the fan speed control. To return to automatic fan operation, press Automatic/AUTO.

Manual override controls

The manual override controls allow you to determine airflow location and fan speed. To return to full automatic control, press Automatic/AUTO.

• Max A/C - Distributes recirculated air through the instrument panel registers. A temperature of 16°C (60°F) will appear in the display window until Automatic/AUTO, another manual override control, or the temperature control has been selected. The A/C compressor will only function if the outside temperature is above approximately 6°C (43°F). Max A/C is noisier than Norm A/C, but more economic and efficient. This mode will reduce undesirable odors from entering the vehicle.
• Norm A/C- Distributes outside air through the instrument panel registers. The A/C compressor will only function if the outside temperature is above approximately 6°C (43°F). Norm A/C is more quiet than Max A/C, but not as economic and efficient.
• Vent-Distributes outside air through the instrument panel registers. The air cannot be cooled below the outside temperature.
• Floor- Distributes outside air through the floor ducts. The air cannot be cooled below the outside temperature.
• Floor & Defrost - Distributes outside air through the windshield defroster ducts, floor ducts and the side window demisters. The A/C compressor will operate automatically if the outside temperature is above approximately 6°C (43°F). The air distributed through the floor ducts will be slightly warmer than that sent to the windshield defroster ducts and the side window demisters.
• Defrost - Distributes outside air through the windshield defroster ducts and the side window demisters. The A/C compressor will operate automatically if the outside temperature is above approximately 6°C (43°F). This mode will clear ice and fog from the windshield.
  

Operating tips

• To reduce fogging under humid weather conditions, place the climate control system in Defrost and Rear Defrost (if equipped) mode before driving.
• To reduce humidity buildup inside the vehicle under warm weather conditions, do not drive with the climate control system in Off mode.
• To reduce humidity buildup inside the vehicle under cold weather conditions, do not drive with the climate control system in Max A/C (if equipped), recirculation control (if equipped) or Off mode.
• Under normal weather conditions, do not leave your vehicle in Max A/C (if equipped), recirculation control (if equipped) or Off mode when turning off the ignition.
• Under snowy or dirty weather conditions, leave your vehicle in Max A/C (if equipped), recirculation control (if equipped), or Off mode when turning off the ignition.
• Remove any snow, ice or leaves from the exterior base of the windshield.
• To increase the efficiency of the A/C (if equipped), drive with the windows slightly open for 2–3 minutes or until the vehicle has been “aired” out.
• Do not place objects under the front seat or over the defroster ducts. They may reduce visibility, fall into the ducts, or degrade the performance of your climate control system.
  

To aid in side window defogging/demisting in cold weather conditions:

1. Select VENT
2. Set the temperature control to full heat
3. Set the fan speed to HI
4. Direct the outer panel vents towards to side windows
   

To increase airflow to the outer panel vents, close the central panel vents.

Do not place objects on top of the instrument panel, as these objects may become projectiles in a collision or sudden stop.
