Automatic heating and air conditioning
The automatic climate control system is controlled by simply setting the desired temperature.
The Full Automatic Temperature Control (FATC) system automatically controls the heating and cooling system as follows;
1. Push the AUTO button. The modes, fan speeds, air intake and air-conditioning will be controlled automatically by temperature setting.
2. Press the temperature control button to set the desired temperature. If the temperature is set to the lowest setting, the air conditioning system will operate continuously.
3. To turn the automatic operation off, select any button or switch of the following:
- Mode selection button
- Air conditioning button
- Front windshield defroster button
- Air intake control button
- Fan speed control switch
The selected function will be controlled manually while other functions operate automatically.
For your convenience and to improve the effectiveness of the climate control, use the AUTO button and set the temperature to 73°F (23°C).
✽ NOTICE
Never place anything over the sensor located on the instrument panel to ensure better control of the heating and cooling system.
Manual heating and air conditioning
The heating and cooling system can be controlled manually by pressing buttons or turning knob(s) other than the AUTO button. In this case, the system works sequentially according to the order of buttons or knob(s) selected.
1. Start the engine.
2. Set the mode to the desired position. For improving the effectiveness of heating and cooling;
- Heating:
- Cooling:
3. Set the temperature control to the desired position.
4. Set the air intake control to the outside (fresh) air position.
5. Set the fan speed control to the desired speed.
6. If air conditioning is desired, turn the air conditioning system on.
Press the AUTO button in order to convert to full automatic control of the system.
Mode selection
The mode selection button controls the direction of the air flow through the ventilation system.
The air flow outlet port is converted as follows:
Refer to the illustration in the “Manual climate control system”.
Face-Level
Air flow is directed toward the upper body and face. Additionally, each outlet can be controlled to direct the air discharged from the outlet.
Bi-Level
Air flow is directed towards the face and the floor.
Floor-Level
Most of the air flow is directed to the floor, with a small amount of the air being directed to the windshield and side window defrosters.
Floor & Defrost
Most of the air flow is directed to the floor and the windshield with a small amount directed to the side window defrosters.
Defrost-Level
Most of the air flow is directed to the windshield with a small amount of air directed to the side window defrosters.
Instrument panel vents
The outlet vents can be opened or closed separately using the thumbwheel.
Also, you can adjust the direction of air delivered from these vents using the vent control lever as shown.
Temperature control
The temperature will increase by pushing the up button. Each push of the button will cause the temperature to increase by 1°F/0.5°C.
The temperature will decrease by pushing the down button. Each push of the button will cause the temperature to decrease by 1°F/0.5°C. When set to the lowest temperature setting, the air conditioning will operate continuously.
Adjusting the driver and passenger side temperature individually
1. Press the DUAL button to operate the driver and passenger side temperature individually. Pressing the right temperature control button will automatically switch to the DUAL mode as well.
2. Press the left temperature control button to adjust the driver side temperature. Press the right temperature control button to adjust the passenger side temperature.
When the driver side temperature is set to the highest or lowest temperature setting, the DUAL mode is deactivated for maximum heating or cooling.
Adjusting the driver and passenger side temperature equally
1. Press the DUAL button again to deactivate DUAL mode. The passenger side temperature will be set to the same temperature as the driver side temperature.
2. Press the left temperature control button. The driver and passenger side temperature will be adjusted equally.
Temperature conversion
If the battery has been discharged or disconnected, the temperature mode display will reset to Fahrenheit.
This is a normal condition.You can switch the temperature mode between Fahrenheit to Celsius as follows; While pressing the MODE button, depress the DUAL button for 3 seconds or more. The display will change from Fahrenheit to Celsius, or from Celsius to Fahrenheit.
Air intake control
This is used to select the outside (fresh) air position or recirculated air position. To change the air intake control position, push the control button.
Recirculated air position
The indicator light on the button illuminates when the recirculated air position is selected.
With the recirculated air position selected, air from the passenger compartment will be drawn through the heating system and heated or cooled according to the function selected.
Outside (fresh) air position
The indicator light
✽ NOTICE
Prolonged operation of the heater in the recirculated air position (without air conditioning selected) may cause fogging of the windshield and side windows and the air within the passenger compartment may become stale.
In addition, prolonged use of the air conditioning with the recirculated air position selected will result in excessively dry air in the passenger compartment.
WARNING
- Continued use of the climate control system operation in the recirculated air position may allow humidity to increase inside the vehicle which may fog the glass and obscure visibility.
- Do not sleep in a vehicle with the air conditioning or heating system on. It may cause serious harm or death due to a drop in the oxygen level and/or body temperature.
- Continued use of the climate control system operation in the recirculated air position can cause drowsiness or sleepiness, and loss of vehicle control. Set the air intake control to the outside (fresh) air position as much as possible while driving.
Fan speed control
The fan speed can be set to the desired speed by turning the fan speed control knob.
The higher the fan speed is, the more air is delivered.
Air conditioning
Push the A/C button to turn the air conditioning system on (indicator light will illuminate).
Push the button again to turn the air conditioning system off.
OFF mode
Push the OFF button to turn off the air climate control system. However, you can still operate the mode and air intake buttons as long as the ignition switch is in the ON position.
The air intake control in your Hyundai Elantra plays a pivotal role in regulating engine performance and cabin climate. It helps manage the blend of outside and recirculated air for optimal combustion and air quality. In cold weather, proper intake balance supports faster engine warm-up and better defrosting efficiency. During high pollution or dusty conditions, switching to recirculated air prevents contaminants from entering the cabin. The system is often automated but can be manually overridden for targeted use. Knowing when to switch air modes enhances cabin comfort and protects sensitive passengers. Periodic maintenance ensures the intake flaps and filters operate smoothly. Misuse or blockage can reduce HVAC effectiveness and strain engine breathing. Learning how to integrate air control with other systems like A/C or defrost maximizes overall efficiency. This smart feature contributes both to environmental cleanliness and personalized comfort.
