★ Top Answer
To deactivate the SOS alert on a Mercedes, you can try the following steps: First, turn off the engine and then turn the key back on. Next, switch on the headlights and keep them on for two minutes. Afterwards, turn off the headlights and switch off the key. The warning message may still appear at the moment, but it should disappear by the next morning. This issue is related to the ECU experiencing a battery voltage problem. By running the headlights for two minutes, the ECU will register a voltage decrease and update the battery voltage status to resolve the problem. If you are still experiencing difficulties, consider taking your vehicle to the dealership for a diagnostic assessment to identify the specific issue.
