What is the reason why the Mercedes-Benz automatic parking cannot be engaged?

Mercedes-Benz automatic parking cannot be engaged because of improper foot technique and lack of familiarity, which can be improved with more practice. Below is a related introduction to automatic parking: Definition: Traditional handbrakes require the driver to manually release the handbrake or skillfully coordinate the clutch and throttle for a smooth start on slopes. The automatic parking function uses a slope sensor to provide precise parking force via the controller. During startup, the parking control unit calculates information from the clutch distance sensor, clutch engagement speed sensor, throttle pedal sensor, etc. It automatically releases the parking brake when the driving force exceeds the running resistance, allowing the car to start smoothly. However, it is best to turn off this function during low-speed parking to avoid frequent activation. Function: It simplifies operation by avoiding the use of handbrakes or electronic handbrakes, and automatic transmission models do not need to frequently switch between D to N or D to P.
Recently, I also encountered a situation where the Mercedes auto-hold function wouldn't engage, which was quite frustrating. As a driver with years of experience, I think there could be several common reasons for this. If the sensors in the brake system become loose or fail, the parking function may not work. Blown fuses are also a common issue, especially during circuit overload or aging. Additionally, if the electronic control module has a software bug or poor contact, it can cause the system to stop responding. Don't forget to check the brake fluid level, as low hydraulic pressure can cause the entire system to fail. When facing such problems, never force the car to drive, especially on slopes where it can easily slip and become dangerous. I recommend visiting a professional repair shop as soon as possible to diagnose the specific fault codes with a diagnostic computer, ensuring precise repairs and preventing minor issues from turning into major problems.
