Which button to press when there is fog inside the car?
2 Answers
To remove fog inside the car, press the front window defogging button. The formation of fog on the windows is caused by the temperature difference between the cold outside and warm inside. Methods to defog: 1. Open the windows slightly to allow air convection when the fog is not heavy. This balances the temperature difference between inside and outside, gradually eliminating the fog; 2. Use the air conditioning system to defog by turning on the fan and cooling switch. The cold air directed at the front windshield will quickly remove the fog; 3. Apply a defogging agent to the inner surface of the car windows and wipe it clean. This not only cleans the glass but also forms a protective film to prevent moisture condensation and fog formation. One application can prevent fogging for about ten days.
I've been driving for almost ten years, and fogging up inside the car is all too common, especially on rainy winter days when a white layer of fog covers the windshield, making it hard to see the road. The way to deal with it is to press the defrost button on the dashboard—the one with the icon of a small square with three wavy lines on top. Pressing it will automatically turn the AC to maximum fan speed, blowing hot air directly at the front windshield, and the fog will disappear in seconds. Remember to turn on the AC first and set the temperature to around 22 degrees for the most comfortable setting—not too cold or too hot. If the fog clears but comes back, it might be because the windshield is too dirty or has an oily film; just wipe it with a clean cloth and try again. To prevent fogging, start the car a few minutes early to warm it up, or on rainy days, dry your shoes before getting in to reduce moisture. Safety comes first when driving—if the fog is too thick to see, find a place to pull over and handle it.
