How to Turn on the External Circulation?
2 Answers
To activate the external circulation, simply press the external circulation button on the air conditioning control panel. Below is relevant information about external circulation: 1. External Circulation Button: The air conditioning control panel features both an external circulation button and an internal circulation button. The internal circulation button icon depicts a small car with an arrow circulating inside it. The external circulation button icon shows a small car with an arrow entering from outside the vehicle. Drivers can locate these buttons on the air conditioning control panel. All car air conditioning systems have internal and external circulation functions. When external circulation is activated, fresh air from outside enters the cabin. 2. When to Use External Circulation: External circulation is suitable when opening windows for ventilation is inconvenient, such as during highway driving. However, when passing through areas with heavy dust or traffic congestion, the internal circulation mode should be used. If external circulation is activated in severely congested areas, exhaust fumes may enter the cabin.
On most cars, turning on the fresh air mode is quite simple. There's usually a button in the climate control area with an icon showing a fan arrow pointing outward from the car or an outward arrow on a recirculation symbol. Press it once to switch to outside air mode. I find this feature extremely useful – like when driving in the countryside with fresh air, pressing it brings in outside oxygen, helping reduce stuffiness or window fogging inside the car. Sometimes when there are many people in the car after a meal with lingering odors, I also use the fresh air mode for quick ventilation. However, I'm careful to avoid using it in city traffic jams, as it would otherwise draw in unpleasant exhaust fumes. Some newer cars offer more convenient touchscreen settings, but manual AC models typically have the button near the center console fan. You'll know it's working when you feel cool air coming in – I recommend using it together with the AC for better results.
