QUESTION ANSWER SOLUTION
With the engine off, the
audio system switches off
after a few minutes of use.
When the engine is switched off, the audio system operating time
depends on the state of charge of the battery.
The switch-off is normal: energy economy mode is activated
automatically to preserve the state of charge of the vehicle's
battery. (See the "Energy Economy Mode" section).
Start the vehicle's engine to increase the battery
charge.
The message "the audio
system is overheated"
appears on the display.
In order to protect the installation if the surrounding temperature
is too high, the audio system switches to an automatic thermal
protection mode leading to a reduction of the volume or stopping of
the playing of the CD.
Switch the audio system off for a few minutes to
allow the system to cool.
