Energy Management

Most control modules, which are needed for the audio system, are connected to the energy management system. This means the MOST-bus switches off if there is a poor energy balance in the vehicle. Depending on the state of the battery, there are different switch-off levels which have an effect on the different control modules. Audio output is not possible after a switch-off level has been activated.

• The MOST-bus will continue to run for a certain amount of time with terminal 15 ignition on and without pressing the button on the multimedia control head (E380). After this time period runs out or depending on the operating condition of the MOST-bus, either a terminal 15 ignition on signal must occur or the ON/OFF button on the multimedia system control head must be operated in order to continue the audio output.
