Ford Fiesta: Climate Control

Ford Fiesta 2009-2019 Owners Manual

Principle of Operation

Outside Air

Keep the air intakes in front of the windshield free from obstruction (such as snow or leaves) to allow the climate control system to function effectively.

Recirculated Air

WARNING

Prolonged use of recirculated air may cause the windows to mist up. If the windows mist up, follow the settings for demisting the windshield.

The air currently in the passenger compartment recirculates. Outside air does not enter your vehicle.

Heating

Heating performance depends on the temperature of the engine coolant.

Air Conditioning

Note: The air conditioning operates only when the temperature is above 39ºF (4ºC).

Note: When you use air conditioning, your vehicle uses more fuel.

The system directs air through the evaporator for cooling. The evaporator extracts humidity from the air to help keep the windows free of mist. The system directs the resulting condensation to the outside of your vehicle, which may cause a small pool to form under your vehicle.

This is normal.

General Information on Controlling the Interior Climate

Fully close all the windows.

Warming the Interior

Direct the air toward your feet. In cold or humid weather conditions, direct some of the air toward the windshield and the door windows.

Cooling the Interior

Direct the air toward your face.

Air Vents

Center Air Vents

Side Air Vent

Manual Climate Control

1. Fan speed control: Controls the volume of air circulated in your vehicle. Adjust to select the desired fan speed.
2. Air distribution control: Adjust to select the desired air distribution. If you select MAX A/C the system distributes recirculated air through the instrument panel air vents. This mode is more economical and efficient than normal air conditioning. Select O to turn the system off.
3. Recirculated air: Press the button to switch between outside air and recirculated air. When you select recirculated air, the button illuminates and the air currently in the passenger compartment recirculates. This can reduce the time needed to cool the interior and reduce unwanted odors from entering your vehicle.
4. Temperature control: Controls the temperature of the air circulated in your vehicle. Adjust to select the desired temperature.
5. Heated rear window: Press the button to defog and clear the rear window of a thin covering of ice.
6. Air conditioning: Press the button to switch the air conditioning on or off. Air conditioning cools your vehicle using outside air. To improve air conditioning when starting your vehicle, drive with the windows slightly open for two to three minutes.

Automatic Climate Control (If equipped)

1. Fan speed: Controls the volume of air circulated in your vehicle. Rotate the control to select the desired fan speed. The setting is shown in the display.
2. Instrument panel: Press the button to distribute air through the instrument panel air vents.
3. Windshield: Press the button to distribute air through the windshield air vents.

   You can also use this setting to defog and clear the windshield of a thin covering of ice.

4. MAX Defrost: Press the button to distribute outside air through the windshield air vents. Air conditioning is automatically selected. The fan is set to the highest speed and the temperature to HI. When the air distribution is set in this position, you are unable to select recirculated air or manually adjust the fan speed and temperature control. Press the AUTO button to return to auto mode.
5. MAX A/C: Press the button to distribute recirculated air through the instrument panel air vents. This mode is more economical and efficient than normal air conditioning.
6. Temperature control: Controls the temperature of the air circulated in your vehicle. Adjust to select the desired temperature.
7. Air conditioning: Press the button to switch the air conditioning on or off. Air conditioning cools your vehicle using outside air. To improve air conditioning when starting your vehicle, drive with the windows slightly open for two to three minutes.
8. Recirculated air: Press the button to switch between outside air and recirculated air. The air currently in the passenger compartment recirculates.

   This can reduce the time needed to cool the interior and reduce unwanted odors from entering your vehicle.

9. Off button: Press the button to switch the system off.
10. Heated rear window: Press the button to defog and clear the rear window of a thin covering of ice.
11. Footwell: Press the button to distribute air through the footwell air vents.
12. AUTO: Press the button to switch the system on and off. The system automatically controls the temperature, amount and distribution of the airflow to reach and maintain your previously selected temperature.

Temperature Control

You can set the temperature between 61ºF (16ºC) and 82ºF (28ºC). In position low, the system switches to permanent cooling.

In position high, the system switches to permanent heating.

Note: If you select either position low or high, the system will not regulate a stable temperature.

Hints on Controlling the Interior Climate

General Hints

Note: Prolonged use of recirculated air may cause the windows to fog up.

Note: A small amount of air may be felt from the footwell air vents regardless of the air distribution setting.

Note: To reduce humidity build-up inside your vehicle, do not drive with the system switched off or with recirculated air always switched on.

Note: Do not place objects under the front seats as this may interfere with the airflow to the rear seats.

Note: Remove any snow, ice or leaves from the air intake area at the base of the windshield.

Manual Climate Control

Note: To reduce fogging of the windshield during humid weather, adjust the air distribution control to the windshield air vents position. Increase the temperature and fan speed to improve clearing, if required.

Automatic Climate Control

Note: Do not adjust the settings when your vehicle interior is extremely hot or cold. The system automatically adjusts to the previously stored settings. For the system to function efficiently, the instrument panel and side air vents should be fully open.

Note: At low ambient temperatures with AUTO selected, the air stream is directed toward the windshield and side windows for as long as the engine remains cold.

Note: When the system is switched off, outside air is prevented from entering your vehicle.

Note: When you select AUTO mode and the interior and exterior temperatures are high, the system automatically selects recirculated air to maximize cooling of the interior. When the desired air temperature is reached, the system automatically selects outside air.

Note: When you select windshield defrosting and defogging, the instrument panel and footwell level functions automatically switch off and air conditioning switches on. Outside air flows into your vehicle.

Maximum Cooling Performance in Instrument Panel or Instrument Panel and Footwell Positions

1. Adjust the temperature control to the lowest setting.

2. Press the A/C and recirculated air buttons.

3. Adjust the fan speed to the highest setting initially and then adjust it to suit the desired comfort level.

Heated Windows and Mirrors

Heated Windows

Use the heated windows to defrost or demist the rear window.

Note: The heated windows operate only when the engine is running.

Heated Rear Window

Heated Exterior Mirrors

Electric exterior mirrors have a heating element that will defrost or demist the mirror glass. They will switch on automatically when you switch the heated rear window on.

Cabin Air Filter

Your vehicle is equipped with a cabin air filter. It is located behind the center console.

The particulate filtration system reduces the concentration of airborne particles such as dust, spores and pollen in the air supplied to the interior of your vehicle.

Note: Make sure you have a cabin air filter installed at all times. This prevents foreign objects from entering the system. Running the system without a filter in place could result in degradation or damage to the system.

The particulate filtration system gives you and your passengers the following benefits:

• It improves your driving comfort by reducing particle concentration.
• It improves the interior compartment cleanliness.
• It protects the climate control components from particle deposits.

Replace the filter at regular intervals. See Scheduled Maintenance.

For additional cabin air filter information, or to replace the filter, see an authorized dealer.
