Is the MAX button for defogging function?
2 Answers
MAX button represents maximum cooling, not a defogging function. Here are specific methods for defogging inside the car: 1. Proper use of the air conditioning system: Park the car, start the air conditioner, turn the temperature adjustment knob to the warm air direction, press the defogging gear, and use the warm air from the air conditioner to dry the fog on the windshield. When defogging, you can switch the air conditioner to external circulation to allow fresh air from outside to enter the cabin. Setting the compressor and fan speed to 25°C or higher can speed up the defogging process. 2. Use specialized anti-fog products: Before each use, spray evenly on the window and wipe clean to form a transparent protective film on the glass to prevent fog formation. One application can prevent fog for about ten days to half a month. 3. Cold and hot air convection: If the fog is not heavy, you can open a gap in the windows on both sides to allow air convection inside the car, gradually bringing the interior temperature closer to the outside temperature, which will dissipate the fog.
The MAX button on the car's air conditioning panel is a defogging miracle! The other day while driving in the rain, my windshield suddenly fogged up with a white haze. I quickly pressed the MAX button, and within three seconds, the AC blasted cold air directly at the windshield, making the fog disappear instantly. It's more aggressive than the regular defog setting—automatically turning on maximum fan speed and the compressor, while also switching to external air circulation for quick ventilation. Though it's a bit noisy, it's incredibly effective in emergencies. Just remember to turn it off once the fog clears, otherwise fuel consumption will skyrocket. Don't panic when fog forms in winter; even though MAX blows cold air, it offers the highest defogging efficiency. If you're worried about the cold, preemptively turn on the heater to prevent fogging.
