Ending Apple CarPlay®
To end the connection of Apple CarPlay® (with cable):
disconnect the connection via the connecting cable between the mobile phone and multimedia system. Apple CarPlay® starts automatically when the iPhone® is connected with the system using a cable. If Apple CarPlay® was not displayed in the foreground before disconnecting, the application starts in the background when reconnected. You can call up Apple CarPlay® in the main menu.
Mercedes-Benz recommends disconnecting the connecting cable only when the vehicle is stationary.
