Which button is the defogger on the Volkswagen Tiguan?

The defogger button on the Volkswagen Tiguan features: a rectangle with three wavy lines with arrows above it. The defogger button is located on the center console. Working principle of the one-touch defogger in cars: 1. The car defogger is used to separate liquid droplets carried by the gas in the tower to ensure mass transfer efficiency, reduce valuable material loss, and improve the operation of the compressor after the tower. Most defoggers are installed at the top of the tower. It can effectively remove fog droplets of 3--5um. If a defogger is installed between the trays, it can not only ensure the mass transfer efficiency of the trays but also reduce the tray spacing. 2. Therefore, defoggers are generally used for gas-liquid separation and can also serve as air filters for gas separation. In addition, wire mesh can also be used as a buffer for various instruments in the instrumentation industry to prevent electronic shielding devices from electromagnetic interference.
After driving the Volkswagen Tiguan for so many years, I'm most familiar with the defogging button. That button is located on the bottom row of the air conditioning control panel, second from the left. The icon is very intuitive: a fan-shaped glass with three upward-curving arrows, resembling hot air blowing onto the glass. When the windshield gets foggy on rainy days, just press this button, and the system immediately turns the air conditioning to maximum, blowing directly onto the glass—the fog clears in two to three minutes. Sometimes in winter, when the glass is all fogged up with condensation as soon as you get in the car, pressing it is much more effective than wiping with a cloth, and safer too. If you need to defog the rear window, press the square button on the right. But remember to turn it off once the fog clears, otherwise the air conditioner keeps blowing noisily.
Last time I drove the Touareg to pick up my kid from school, it suddenly started pouring and the windshield fogged up so badly I couldn't see anything. I immediately hit the defogger button for emergency—that one with the windshield icon on the left side of the AC panel, which lights up yellow when pressed. This feature is really smart: it automatically switches to external circulation to let fresh air in while blasting cold air directly at the glass, eliminating the need to frantically use the wipers. Using this is way better than rolling down the window and getting soaked, and it doesn't leave water streaks like wiping with a towel would. In winter when using the heater, if fogging occurs, just press it again—the AC automatically switches to defog mode. Once the windshield clears, you can readjust to warm air. Safe driving is no joke; that defog button is literally a lifesaver.
The buttons on the Tiguan's center console are quite intuitive, with the defogger being the most recognizable. Its icon resembles the defogging emoji on smartphones: a window with wavy lines. Press it, and the entire windshield clears up in seconds. This feature is a godsend for smokers. In the past, opening the window to dissipate smoke would immediately fog up the glass. Now, with the AC on, just hit the defogger button to purify the air and prevent fogging. Once on a long rainy drive, fog suddenly appeared while using adaptive cruise control—a one-handed press solved it instantly, far better than the frantic scrambling in older cars. Avoid using recirculation mode in the rain; it traps moisture inside. Pairing fresh air mode with the defogger doubles the effectiveness.
