Defrost function. The incoming outside air is directed straight onto the front windshield, and the interior air recirculation mode is automatically turned off. The reason for fogging is that the temperature inside the car is higher than the outside temperature, causing water droplets to condense on the glass surface. Therefore, it is necessary to lower the temperature inside the car. To defog, press the front window defogging button. After pressing, the air volume from the vents on the center console will decrease.

I always drive a Volkswagen New Bora. When encountering window fogging, I first start the car, then locate the air conditioning control panel near the steering wheel—there's a front window defogging button with an icon resembling a small fan, which I simply press. Usually, I increase the fan speed and set the temperature to the warm air direction to allow the AC to quickly dehumidify. Once the fog clears, I adjust back to comfort mode. In winter, I make a habit of activating it in advance before driving off to prevent blurred vision. Through daily use, I've found that keeping windows clean and avoiding excessive interior humidity can also reduce fog formation—for example, leaving a slight window gap for ventilation after parking. These little tricks give me more peace of mind while driving, especially in rainy or foggy conditions to prevent accidents. Anyway, the New Bora's design is quite user-friendly, with quick response and effortless operation, making ownership quite hassle-free.

When encountering fog while driving, my approach is to press the defogging button on the center console. That button is located near the dashboard of the Volkswagen New Bora, with clear markings. I usually turn on the A/C cooling simultaneously and pair it with the external circulation mode, making the air drier. The principle is simple: the air conditioner absorbs moisture, and the hot air blows onto the windshield, dispersing the fog. If the fog is heavy, I also use the wipers along with the defrost function to speed up the clearing process. Besides operation, regular maintenance of the air conditioning system is crucial. For example, replacing the filter can prevent blockages and improve efficiency. I think car design should be this considerate, making it easy even for beginners to get the hang of it quickly. Overall, while defogging may seem minor, it’s vital for driving safety. I take the time to adjust it properly before setting off, never rushing.

Here's how I deal with foggy windows: start the car, press the defog button (very prominent on the Volkswagen New Bora), turn up the fan speed, and set the airflow direction to the windshield. The fog clears within minutes. If it's cold, preheating the car beforehand makes it even more convenient. Simple and effective.
