Which button can remove the fog from the front windshield?

[McJosie]

The button with a front window-shaped icon represents the front windshield defogging and defrosting function, while the rectangular icon represents the rear windshield defogging and defrosting. Here are the methods to remove fog from the front windshield: 1. First, turn on the car's air conditioning and set it to the hot air position. Then activate the external circulation mode and direct the air vents toward the front windshield to blow hot air directly. This allows outside air to enter the vehicle. Under normal circumstances, the fog on the front windshield will dissipate within about 5 minutes. This defogging method utilizes the heat generated by the engine after it starts operating. As mentioned in window defogging techniques, this approach does not increase the vehicle's fuel consumption and is an economical and effective defogging method. Although the defogging speed is not very fast, combining it with wiping the windshield with a towel makes it both economical and practical. 2. If the fog is not heavy, you can slightly open the side windows to create a gap. This allows air convection inside the car, gradually equalizing the interior temperature with the outside temperature, which will help dissipate the fog. This achieves the same effect as using the air conditioning without increasing fuel consumption. However, this method is not suitable for rainy days.
