The recirculation symbol is the best mode in the car AC system. The symbol of this mode is an image of a car with arrows pointing inside on a white background. This symbol has two modes in it.

  • Recirculation mode
  • Fresh air mode

You may choose between these two modes by pressing this recirculation symbol. Both these modes hold different functionality. 

Recirculation mode: If you choose the recirculation mode, the car AC system will use the air inside the car’s compartment. This mode is useful for instant cooling or heating. If you press this mode, you will instantly feel cool air coming out from the vent in case of AC and warm air in case of the heater. 

This method is ideal if you want instant or turbo cooling of the compartment, eliminate any foul smell, and avoid outside pollutants and allergens. 

Fresh air mode: This mode works completely opposite from the recirculation mode. If you choose fresh air mode, the car AC system will draw air from outside the compartment to bring you the best cooling or heating effect. This mode is comparatively slower than the recirculation mode, and the car’s cooling or heating will be gradual. 

This mode is ideal if you want to add fresh air and oxygen to your car’s compartment and improve the car’s ventilation. 

Defrost Symbol

The other symbol is the defrost symbol, which is often white and includes an image of a windshield with wavy lines on it. It indicates that the windshield can be defrosted or defogged by directing air toward it. When you push this button, the system will heat the windshield and, if available, defrost the back windows. This helps to remove your windshield of ice, snow, moisture, or fog while enhancing your driving vision.

This is one of the best features you should be familiar with if you reside in high altitudes. 

Auto Mode Symbol

The Auto mode symbol conserves your energy and efforts of again and again manually changing different modes. Instead, it automatically makes the changes according to your preferred settings. 

The AUTO mode in your car ac control panel is the button with an “A” marked on it in white. The function of the symbol is to set up the temperature and other settings based on your previous settings. You can still adjust the temperature by rotating the knob manually or pressing the up and down arrow button on the dashboard. 

This mode will also conserve fuel as the system automatically turns off the compressor when the compartment is cold enough. It will also reduce noise and pollution to the environment.

It is important to know the meaning of the car AC button or symbols because it will help you identify the purpose of each symbol. Each symbol in your car ac control panel serves a different purpose, and being a person who uses a car, it is vital to know about these features for effortless driving.

In conclusion, the icons that symbolize the numerous button operations are called the symbols for car air conditioning. The symbols may differ among different models of the car.
