Where is the Mercedes-Benz windshield defogging button located?

The Mercedes-Benz windshield defogging button is located on the air conditioning control panel below the CD player. Below are specific methods for defogging the interior: 1. Proper use of the air conditioning system: Park the car, start the air conditioning, turn the temperature adjustment button to the warm air direction, press the defogging button, and use the warm air from the air conditioning to dry the windshield fog. During defogging, you can switch the air conditioning to external circulation to allow fresh air 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 windows and wipe clean to form a transparent protective film on the glass, preventing fog formation. One application can prevent fogging for about ten days to half a month. 3. Cold and hot air convection: If the fog is not heavy, you can open a small gap in the side windows to allow air convection inside the car. As the interior temperature gradually approaches the outside temperature, the fog will dissipate.
I've been driving a Mercedes for several years. The front defroster button is usually located on the air conditioning control panel of the center console, with an icon of a windshield featuring upward-curved wavy lines, indicating airflow defogging. On C-Class or E-Class models, its position is very prominent—just press it and the air conditioning system will activate high-speed dehumidification, instantly clearing fog. I recommend turning on the AC cooling switch and external circulation mode first if the fog is heavy, as this speeds up dehumidification. Newer models like the A-Class may integrate it into the touchscreen quick menu, but the button layout is similar. Develop a habit of pressing a few times to locate it during daily driving, avoiding blurred vision in rainy conditions. Cleaning the glass surface can also help speed up defogging.
