12. How can I check if the system is working?
In principle, it is not necessary to test the system. In case of technical faults, a message will appear in the instrument cluster. If required, the customer can, of course, personally test the system. To do so, it suffices to briefly press the SOS button at standstill. The countdown begins (acoustic signal & presentation in the instrument cluster), so that it can be cancelled within a short time frame without establishing a connection to the BMW call centre. If an emergency call is inadvertently made, it is important to speak to the call centre agent to inform them that it was a "system test".
