What is the reason for the Mercedes-Benz auto hold not engaging?

[AdelineAnn]

Mercedes-Benz auto hold not engaging is due to poor foot technique and lack of adaptation, which can be improved with more practice. Below is relevant information about auto hold: 1. 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 auto hold function uses a slope sensor to provide precise braking 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. When the driving force exceeds the running resistance, the parking brake is automatically released, allowing the car to start smoothly. However, it is best to turn off this function during low-speed parking to avoid frequent activation. 2. 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.
