To stop the SOS Tele inoperative message on a 2008 Mercedes-Benz CLS 550, you can try resetting the system by disconnecting the car battery for a few minutes and then reconnecting it. If the issue persists, ensure that the telematics control unit is functioning properly and that any necessary software updates are applied. Additionally, you may need to visit a dealership or a qualified mechanic to diagnose potential hardware issues or to reset the system using a diagnostic tool.
