It is a car symbol with an arrow pointing from the outside into the car, which represents the external air circulation button. When the vehicle's air conditioning or heating system is activated, using the external air circulation allows outside air to enter the car, providing ventilation. Here are additional details: Using external air circulation: When the air inside the car is stale, activating the external air circulation brings in fresh air, effectively improving the air quality inside the vehicle. This is especially useful for new cars, as it helps remove odors. On rainy days, using the external air circulation prevents fogging on the windshield and other windows, enhancing driving safety. Do not use internal air circulation for extended periods: While driving, it is recommended to switch to external air circulation for at least ten minutes every 40 to 50 minutes. Otherwise, the carbon dioxide concentration inside the car can become very high, causing fatigue and drowsiness among passengers and the driver, which can compromise safety.

After driving for so many years, I find the car's external circulation button quite easy to locate. The icon usually depicts a small car with an arrow pointing from the outside into the car, symbolizing the control that allows fresh outside air to enter the vehicle. It's typically positioned in the middle or on the side of the air conditioning control panel, right next to the internal circulation button, which features an arrow circling inside the car. I particularly enjoy using it on rural roads with fresh air, as it makes breathing inside the car much more comfortable and prevents stuffiness. However, during traffic jams or on smoggy days, I switch to internal circulation to avoid inhaling exhaust fumes. Operating it is straightforward—just a press of the button, though some newer models use touchscreen settings. It's advisable to check the air filter during regular maintenance; a clogged filter can reduce efficiency, making the airflow less satisfying. In short, locate that icon, experiment with it in different environments, and you'll get the hang of it over time.

In daily car use, the exterior air circulation button is designed intuitively, usually featuring a small car icon with an inward-pointing arrow. In my Volkswagen model, it's located among the air conditioning buttons on the center console, near the temperature knob. When activated, it introduces outdoor air, which is particularly useful for maintaining ventilation during long drives to prevent dizziness. Compared to the interior circulation mode, which recirculates air within the cabin to minimize external pollutants, it's important to avoid prolonged use in dusty areas to prevent filter clogging. During each maintenance service, I have the technician inspect the air conditioning system to ensure clean ducts. Simply switching between modes can significantly improve driving comfort, especially for quick cooling in hot weather.

From my veteran driver experience, the external air circulation button is the icon on the AC panel with an arrow pointing into the car, prominently located in the control area. Press it while driving, and fresh air comes right in. I usually activate it during morning commutes to refresh the cabin air. Don't confuse it with the internal recirculation mode. Easy to operate without affecting other functions.

Locating that button in the car is easy - it features an icon of a car with an arrow pointing inward, representing the external circulation mode. On my Honda model, it's a small button positioned at the corner of the control panel, requiring just a gentle press to operate. I frequently use it during park drives when the intake draws in fresh air to improve cabin air quality; remember to switch back to internal circulation when returning to the city to avoid pollution. For maintenance, cleaning the filter every six months is recommended. This intuitive design helps first-time users master it quickly.

How often should the coolant be replaced in a Kia K2?

It is generally recommended to replace the coolant in a Kia K2 every two years or 40,000 kilometers. Below are the steps for replacing the coolant in a Kia K2: 1. The coolant drain outlet is located at the bottom of the radiator; the drain outlet is right beneath the radiator. 2. After draining the coolant, pour in a 2L bottle of coolant and start the engine to flush it. Do not run the engine for too long; about one minute is sufficient. 3. A full coolant replacement requires 4L. After draining, initially pouring in a 2L bottle of coolant may make it seem full, but this is just an illusion due to air in the radiator. Start the engine to expel the air, and you will see the coolant level drop. Then, pour in the remaining coolant.
