How to turn on the air conditioning external circulation?
4 Answers
To turn on the air conditioning external circulation, follow these steps: Locate the button with a car-shaped icon where the arrow points from outside the car into the car, then press it once to activate the external circulation. The difference between internal and external circulation: When air is drawn from outside the car, it is in external circulation mode; if the air comes from inside the car, it is in internal circulation mode. The air conditioner can control the temperature inside the cabin, heating or cooling the air to maintain a comfortable level. It can also remove humidity from the air, drying it to absorb body sweat and create a more comfortable environment. The air conditioner can intake fresh air, providing ventilation and filtering out dust and pollen from the air.
I remember when I first started driving, I didn’t know how to turn on the air conditioning’s external circulation either, but I figured it out later. Look for the air conditioning control panel in the car—there’s usually a button marked with an arrow rotating inside the car—that’s the internal circulation button. Press it to turn off its light, and you’ll switch to external circulation mode. This way, fresh air comes in from outside, making breathing in the car much smoother, especially on long drives—using external circulation is very effective at preventing fogging. Just avoid using it in heavy traffic to prevent inhaling exhaust fumes; on the highway, closing the windows and using it can reduce noise. It’s simple and safe to operate. I recommend regularly cleaning the air conditioning filter to ensure air quality.
For those who know a bit about cars, turning on the air conditioning's external circulation is super easy: On the center console, there's a button with a symbol resembling air circulating from inside the car to the outside—just press the internal circulation button to turn off its light. This mode draws in outside air, helping with dehumidification and odor removal, and is especially quick at preventing fogging in winter. I often use this trick while driving—it's energy-efficient and comfortable, especially during long trips to avoid keeping the internal circulation on for too long, which can lead to insufficient oxygen. I recommend friends give it a try; combining it with the air conditioning's temperature settings makes for a smarter approach.
After driving on highways frequently, you'll realize how quick it is to switch to fresh air mode: Locate the AC button—the recirculation light indicates cabin air is being recycled; press to turn it off for fresh air intake. Benefits include fresher cabin air and effective defogging on rainy days. Avoid using it in traffic jams to prevent exhaust fumes. Just a simple press does the trick.
