How to Turn on the Outside Air Circulation in a Sedan?
2 Answers
To activate the outside air circulation in a sedan, you can directly press the button on the center console. The symbol for the outside air circulation button is an arrow pointing from outside the front windshield into the car. Some vehicles do not have a dedicated outside air circulation button but only an inside air circulation button. Typically, when the light on the inside air circulation button is on, it indicates inside air circulation is active; pressing it again to turn off the light switches to outside air circulation mode. When using the car's air conditioning, it's advisable to alternate between inside and outside air circulation. During hot summer days, if the car has been exposed to the sun, it's recommended to first turn on the outside air circulation to expel the hot air after entering the car. After a few minutes, when the temperature inside and outside the car balances, you can then switch to inside air circulation.
Activating the exterior air circulation in a sedan is actually quite simple. I frequently use this feature while driving: First, locate a button on the instrument panel or the air conditioning control panel with a small car and outward arrow symbol, or labeled 'Exterior Circulation,' then press it to activate. This allows fresh outside air to enter the vehicle, which is especially useful when the car is crowded or the air feels stuffy—for instance, during long highway drives to prevent dizziness. I recommend turning it on in suburban areas with good air quality, avoiding congested city roads to prevent inhaling exhaust fumes. On rainy days, it also helps defog the windshield; turning on exterior circulation along with the blower is very effective when cold air causes fogging. Just remember not to confuse it with the interior circulation button, which recirculates the air inside the car. Regularly checking the cabin air filter is also important to avoid dust buildup affecting performance—I replace the filter every six months to keep the system running smoothly. This small trick significantly improves driving comfort.
