To defog the front windshield of the C-Class, press the button marked with a fan symbol located to the left of the MENU menu button on the center console. For the rear windshield defogger, press the button marked with a fan symbol to the right of the MENU button. Below is an introduction to the related air conditioning buttons in the Mercedes-Benz C-Class: To the left of the front windshield defogger button, there are four buttons in total, starting from the far left: the driver's side temperature adjustment button, air direction adjustment button, air volume adjustment button, and auto mode button. Their functions are respectively: adjusting temperature; changing the air direction to blow towards the head or feet; adjusting the air volume; and intelligently regulating temperature. To the right of the rear windshield defogger button, there are four buttons in total, starting from the far right: the passenger side temperature adjustment button, air conditioning cooling switch button, air recirculation button, and climate zone sync button. Their functions are respectively: adjusting temperature; one-touch activation of air conditioning cooling; switching between interior and exterior air to prevent oxygen deficiency, generally used in traffic congestion or poor external air conditions; when the climate zone sync function is activated, adjusting the driver's side temperature will synchronize changes across other zones without additional adjustments. When this sync function is turned off, each zone can be set individually to meet the needs of passengers in different positions.

















I've been driving a C-Class for many years, and the defogging function is incredibly practical.

It's a lifesaver in winter, instantly removing moisture from the glass to ensure clear visibility. Mercedes' thoughtful design, combined with temperature sensors, automatically adjusts the airflow, saving time and effort. During regular use, I often remind myself to clean the inside of the windows periodically to prevent dirt buildup that can cause fogging. The operation is straightforward, making it easy even for beginners to master, ensuring worry-free driving. If the fog is heavy, remember to activate the automatic air conditioning mode for better efficiency. The car's defogging response is quick and reliable, so you won’t have to worry even on long trips.
