Multifunction camera malfunction: Usually caused by dirt, but since the camera is located inside the vehicle, this is rarely the cause of the issue. Below is some related information about Mercedes-Benz: 1. Name meaning: "Mercedes" means happiness, implying that the cars produced by Daimler will bring happiness to their owners. Mercedes-Benz, a German automotive brand, is considered one of the most successful premium car brands in the world, renowned for its perfect technical level, rigorous quality standards, innovative capabilities, and a series of classic coupe models. 2. Premium products: Currently, it mainly produces C-Class (mid-range sedans and coupes), E-Class (high-end sedans and coupes), S-Class (luxury sedans and coupes), and G-Class (SUV off-road vehicles).
I've been driving a Mercedes for several years, and the limitation of the Active Brake Assist system is a common annoyance. Usually, it's because the radar sensor or camera at the front is covered by dirt, such as mud, bird droppings, or ice in winter blocking the view. Occasionally, the software can also act up, requiring an update or system reset. These Mercedes assistance features are quite smart but not very dirt-resistant; driving in the city for long periods with too much dust can easily cause issues. If the dashboard shows a limitation warning, it's best not to risk driving on the highway; instead, find a safe place to park and check the sensor area. Last time I went to the car wash, the staff cleaned the lens thoroughly, and it returned to normal. Overall, addressing the issue early prevents small problems from becoming big ones. Regular checks and maintenance are key.
I noticed that when this Mercedes system is limited, the automatic braking function fails, which is quite nerve-wracking. The causes are mostly related to sensing devices, such as obstructions on the radar detector or a dirty camera, especially more frequent after rain or snow. It could also be due to loose wiring connections causing signal interruptions. My experience is that once a limitation warning appears, immediately slow down and pull over to check if the areas around the front bumper and windshield are clean. Regular maintenance focusing on cleaning these areas can reduce issues. This topic is often discussed in Mercedes owner groups, with the general advice not to ignore the warnings, as it poses significant safety risks. Promptly visiting a professional shop for a scan can quickly resolve minor issues.
