ANSWER
For optimum sound quality, the audio settings for Loudness,
Ambience, treble, Bass, Volume can be adapted to the different
sound sources, which may result in audible differences when
changing source.
When the engine is switched off, the system's operating time
depends on the state of charge of the battery.
the switch-off is normal: the system switches to economy mode and
switches off to prevent discharging of the vehicle's battery.
SOLUTION
Check that the audio settings (Loudness,
Ambience, treble, Bass, Volume) are adapted to
the sources listened to. Adjust Balance, treble
and Bass to the middle position, select the
"None" musical ambience and set the loudness
correction to the "Active" position in CD mode or
to the "Inactive" position in radio mode.
Start the vehicle's engine to increase the battery
charge.
