Where is the BMW SOS emergency rescue battery located?

[SanEsther]

BMW SOS emergency rescue battery is located inside the roof emergency rescue module. Below are specific details about BMW SOS: 1. SOS emergency rescue function: If the SOS emergency rescue becomes unavailable or shows abnormal assistance, it should be promptly diagnosed and repaired at a 4S shop using computer diagnostics. If hardware failure or battery fault codes appear, it indicates battery failure or insufficient charge requiring replacement. The SOS emergency rescue function can be activated via the SOS emergency button in the multimedia area or on the sunroof ceiling, ensuring immediate resolution of emergencies encountered during driving. 2. Sending distress signals and GPS positioning data: When the vehicle is involved in a major accident (such as severe collision impact, rollover, or fall shock), once the airbags deploy, the SOS emergency rescue function will automatically activate. By sensing the vehicle's condition through onboard hardware after the accident occurs and matching pre-set emergency conditions in the system, it will determine an emergency situation. Then, it will automatically connect with the BMW call center via the built-in telematics SIM card and send distress signals along with GPS positioning data to the receiving platform, facilitating immediate action by emergency responders.
