Methods to release the P gear when a Mercedes-Benz has no power: 1. ESM emergency P gear release: Locate the storage compartment on the central console, insert a pen along the guide hole to press the lever, and use the pin inside the R and P lock solenoid valve to unlock the P gear lock. 2. ISM emergency P gear release: Connect the DAS diagnostic tool to the ISM module, activate the menu, select to shift the transmission into neutral, press F2 and F3 in sequence to complete the unlock. The Mercedes-Benz B200 is a compact model under the Mercedes-Benz brand. Taking the Mercedes-Benz B-Class 2021 B180 Fashion model as an example, its body dimensions are 4423mm in length, 1796mm in width, and 1555mm in height, with a wheelbase of 2729mm. The body adopts a 5-door, 5-seat hatchback structure, and the powertrain is equipped with a 1.3L turbocharged engine, matched with a 7-speed dual-clutch transmission.
I've been driving a Mercedes for many years and have encountered situations where the battery died and the P gear got locked. The P gear getting stuck is usually because the electronic gear shift system relies on the battery for power, and once the voltage is insufficient, the gear gets locked. The method to release the P gear is generally to find an emergency release button near the gear shift lever, usually located on the side or under the mat of the console, with the position varying by model. Once found, press the button with your hand or a small tool while gently pulling the gear shift lever to exit the P gear. Always ensure the car is turned off and the handbrake is engaged before operating to prevent the car from sliding. Regularly check the battery life to avoid problems in remote areas. If this happens frequently, it's recommended to visit a 4S shop to check the circuit and alternator voltage to prevent more serious failures.
Last time I came back from a business trip, I found my Mercedes-Benz completely unresponsive in the garage—turned out the battery was dead and the transmission was stuck in Park. After half an hour of struggle, I finally figured it out: lift the cover under the front passenger seat, and there's a small red lever inside. Pull it hard to manually release the gear. Sharing this experience to remind everyone—don't panic. Most Mercedes models have this mechanical backup designed to be simple and practical. It's best to check your manual and note the location beforehand, as details vary by model. By the way, when dealing with battery drain, avoid randomly jumping the ignition to prevent blowing fuses. After jump-starting, remember to start the engine before shifting gears for safety. Regular battery maintenance can help you avoid such hassles.
