Which button to press when the car window is fogged up?

[DominicMarie]

To defog the car window, activate the front windshield defogging mode, then turn on the air conditioning cooling AC switch and lower the temperature. The fog will clear quickly. For automatic air conditioning, simply press the one-touch defrost button, and the remaining operations will be performed automatically. If you want to use the heating system to defog, it is recommended to stop the car first and let the hot air completely dry the moisture inside the car, and the fog will disappear. When the car window is fogged up, press the external circulation button to introduce outside air into the car, which can remove the fog faster. Front windshield defogging works by directing the air conditioning airflow to the front windshield, thereby reducing the temperature difference on both sides of the glass to achieve the defogging effect. When the rear window is fogged up, the water vapor can be evaporated through the rear window heating function, thus achieving the defogging effect.
