How to Turn on the Vehicle's External Air Circulation?
2 Answers
The vehicle's external air circulation can be activated by pressing the button on the center console. The symbol for the external air circulation button is an arrow pointing from the outside of the front windshield into the vehicle, while the symbol for the internal air circulation button is an arrow forming a circle inside the vehicle. The external air circulation draws air from outside the car into the interior, similar to opening a window for ventilation, but it filters out impurities and harmful gases from the external air, preventing them from entering the cabin and polluting the environment. It is advisable to use external air circulation when driving on highways, while internal air circulation is more suitable for city roads. The vehicle's cabin air filter should be inspected and cleaned every year to prevent blockages that could impair the normal functioning of the air conditioning system.
I often see my friends struggling with how to turn on the external air circulation in their cars. Actually, it's quite simple, but you need to follow the steps. First, start the vehicle's engine, then look at the air conditioning control panel on the center console. There are usually several buttons or knobs there. Find the one with a small car icon and an arrow pointing outward—some models may directly label it "External Circulation" or have a switch for "Internal/External" air. Gently press it with your finger; when the indicator light turns on, it means you've switched to external air mode. I recommend trying it out more often, like turning it on while driving, to avoid stuffy air inside the car. It’s especially effective for long-distance driving or preventing window fogging in winter. Additionally, newer cars might have this function in the touchscreen menu, while older models rely entirely on physical buttons. Remember, don’t rely too much on auto mode—manual control is more flexible. It’s also great for ventilation on rainy days. Using it regularly isn’t difficult; just get familiar with your car’s control panel.
