How to Use the Defogger?

Turn off the AC switch and adjust to the defogging and downward blowing mode. The following introduces methods for defogging a car: 1. Turn on the cooling: Activate the car's air conditioning system to cool, directing cold air onto the fogged glass, and enable the defogging mode in the air conditioning; 2. Wipe the outside of the glass: Mix detergent with water and apply it to the outside of the car glass with absorbent cotton or a clean, soft cloth; 3. Air convection: If the fog inside the car is not heavy, open the sunroof or window to allow indoor air to circulate; 4. Install a defogging function: Install a window heating defogging function.

When encountering foggy windows while driving, I usually handle it this way: right after starting the vehicle, I press the defog button on the AC control panel - the icon typically shows a fan with a wavy line representing fog. I prefer setting the fan speed to maximum (level 3-4) and adjusting the temperature to around 25-30°C, as the hot air quickly evaporates moisture. Remember to switch to external circulation mode to let fresh air in and reduce humidity; prolonged use of internal circulation can accumulate breath moisture and worsen fogging. Pre-warming the car in winter helps, while in summer, turning on the AC compressor can cool and dehumidify. Don't forget to press the rear window heating grid button if available, as it melts condensation droplets. Keeping windows clean is crucial too - regularly wiping them with a slightly damp cloth reduces fog formation, and avoid oily cleaners that impair effectiveness. In short, this simple yet practical method ensures clear visibility for safer driving.

The defroster is my lifesaver for safe driving! When rain or heavy fog blurs the windshield, I immediately pull over, engage the handbrake, and activate the defrost function. Press the fan button, set the airflow specifically toward the front windshield, crank the fan speed to the highest setting, and adjust the temperature to a cozy 30°C or above. If there’s a recirculation switch in the car, make sure to turn it off to let dry air in and balance the temperature difference between inside and outside; recirculation tends to trap humidity, leading to faster fogging. Don’t forget to press the rear window heating button to melt water droplets and maintain clear visibility. Preventing fog is crucial—I avoid leaving open water bottles or damp items in the car to minimize moisture. If fog suddenly appears while driving, stay calm, slow down, and then operate the controls to ensure stability. Regularly test the defroster’s responsiveness to avoid malfunctions in critical moments. This method is incredibly reliable during drastic weather changes.

Using the defroster is simple for beginners: After getting in the car, I locate the defrost button on the AC panel and press it. It automatically directs airflow to the windshield. I usually set the fan speed to medium, with the temperature between 20-25°C, and wait about a minute for the fog to clear before driving. If the rear window fogs up, press another button with a line icon to activate the heated defrost. Remember to use the external circulation mode and don't close the windows too tightly. In hot summers, use cold air for better results, while warm air is more effective in winter; the A/C button can also help quickly dry the air sometimes. Just follow these simple steps, and your vision will clear up instantly, ensuring a safe drive.
