How to Defog the Front Windshield of the Tiguan?

[DeAlivia]

When using the air conditioning to defog, simply press the defog button. Additional extended information is as follows: 1. When the front windshield fogs up: The outside temperature is lower than the inside temperature, and accordingly, the front windshield temperature is also lower than the inside temperature. This causes the water vapor inside the car to condense into small droplets on the glass when it meets the cold surface, attaching to the glass surface and creating a foggy appearance on the window. This situation usually occurs on rainy days or in winter. 2. The reason for fogging: For the mid-to-low-end Tiguan models with manual air conditioning, you can choose the front window defogging mode. The reason for fogging is that the inside temperature is higher than the outside temperature, causing water droplets to condense on the glass surface when they meet the cold. Therefore, simply lowering the inside temperature can achieve the defogging effect.
