Which button to press for fog inside the car?
2 Answers
For fog inside the car, press the front window defogger button. The formation of fog on the windows is caused by the temperature difference between the 'cold outside and warm inside.' The temperature inside the car is higher than the outside temperature, leading to the formation of fog. If the fog is not heavy, you can open a small gap in the side windows (avoid doing this when it's raining). This allows air convection inside the car, gradually equalizing the interior temperature with the outside temperature, which will dissipate the fog. The advantage of this method is that it achieves the effect of turning on the air conditioning without increasing fuel consumption. However, this method is not applicable in all situations, such as during extreme cold or rain.
I've driven many cars before, and when there's fog inside the car, I usually press the front windshield defogger button with the fan-shaped icon, typically located on the air conditioning control panel or near the steering wheel. As soon as I notice fog, pressing this button quickly activates the fan to blow air onto the glass, clearing the view. This is caused by moisture and temperature differences, so I usually turn on the AC function of the air conditioning, which helps dehumidify and dry the air a bit. Also, a reminder: when there's heavy fog inside the car in winter, don't rush to turn up the temperature too high, as it can increase the temperature difference on the glass, making it prone to fogging up again. I often check if the air filter is clean, as a dirty one can increase the chances of fogging. Safe driving relies on clear visibility, so when encountering heavy fog, slow down and find a place to stop, solve the issue first, then get back on the road.
