Mercedes-Benz C-Class's OBD interface is located below the steering wheel on the left side. The functions of OBD are: OBD, as an abbreviation of a proprietary term, stands for On-Board Diagnostics, which means the vehicle's self-diagnosis system in Chinese. This system can monitor the working conditions of the engine's electronic control system and other functional modules of the vehicle in real-time during operation. If any abnormal conditions are detected, it will determine the specific fault according to a specific algorithm and store it in the system's memory in the form of a Diagnostic Trouble Code (DTC). The useful information obtained from the system's self-diagnosis can assist in vehicle maintenance and repair. Maintenance personnel can use the vehicle's original specialized equipment to read the fault codes, quickly locate the fault, facilitate vehicle repairs, and reduce the time required for manual diagnosis. The instructions for the Mercedes-Benz C-Class handbrake are as follows: The Mercedes-Benz C-Class uses an electronic handbrake, which does not require manual operation. The handbrake is automatically engaged when the engine is turned off and the door is closed. If manual operation is desired, there is a button marked with a "P" below the steering wheel on the left side. Pressing it engages the handbrake, and pulling it releases the handbrake. When shifting to P gear and turning off the engine, the dashboard automatically displays a "P" symbol, indicating that the electronic handbrake is automatically engaged. For temporary parking, you can shift to N gear and manually press the electronic handbrake. Older traditional cars usually use a mechanical handbrake, but now most cars have started to adopt electronic handbrakes. The electronic handbrake is a technology that achieves parking braking through electronic control.
