FREQUENTLY ASKED QUESTIONS  
QUESTION  
ANSWER  
SOLUTION  
There is a difference in  
sound quality between  
the different audio  
sources (radio, CD,  
CD changer...).  
For optimum sound quality, the audio settings (Volume, Bass, Treble,  
Ambience, Loudness) can be adapted to the different sound sources,  
which may result in audible differences when changing source (radio, CD,  
CD changer...).  
Check that the audio settings (Volume, Bass,  
Treble, Ambience, Loudness) are adapted to  
the sources listened to. It is advisable to set  
the AUDIO functions (Bass, Treble, Front-Rear  
Balance, Left-Right Balance) to the middle  
position, select the musical ambience "None"  
and set the loudness correction to the "Active"  
position in CD mode or to the "Inactive" position  
in radio mode.  
The CD is ejected  
automatically or is not  
played by the player.  
The CD is inserted upside down, is unplayable, does not contain any audio  
data or contains an audio format which the player cannot play.  
- Check that the CD is inserted in the player the  
right way up.  
- Check the condition of the CD: the CD cannot  
be played if it is too damaged.  
- Check the content in the case of a recorded  
CD: consult the advice in the "Audio" section.  
- The audio equipment's CD player does not  
play DVDs.  
The CD is protected by an anti-pirating protection system which is not  
recognised by the audio equipment.  
- Due to inadequate quality, certain recorded  
CDs will not be played by the audio system.  
The CD player sound  
is poor.  
The CD used is scratched or of poor quality.  
Insert good quality CDs and store them in  
suitable conditions.  
The audio equipment settings (bass, treble, ambiences) are unsuitable.  
Set the treble or bass level to 0, without selecting  
an ambience.

The stored stations do  
not function (no sound,  
87.5 Mhz is displayed...)  
Press the BAND AST button to return to the  
waveband (AM, FM1, FM2, FMAST) on which the  
stations are stored.  
Tune to a radio station which broadcasts trafc  
information.  
The trafc announcement  
(TA) is displayed. I do  
not receive any trafc  
information.  
The radio station is not part of the regional trafc information network.  
The quality of reception  
of the radio station  
listened to gradually  
deteriorates or the  
stored stations do  
not function (no  
The vehicle is too far from the transmitter used by the station listened to or  
there is no transmitter in the geographical area through which the vehicle  
is travelling.  
Activate the RDS function to enable the system  
to check whether there is a more powerful  
transmitter in the geographical area.  
The environment (hills, buildings, tunnels, basement car parks...) block  
reception, including in RDS mode.  
This phenomenon is normal and does not  
indicate a failure of the audio equipment.  
sound, 87.5 Mhz is  
displayed...).  
Have the aerial checked by a CITROËN dealer.  
The aerial is absent or has been damaged (for example when going  
through a car wash or into an underground car park).  
Deactivate the RDS function if the phenomenon  
is too frequent and always on the same route.  
Sound cut-outs of  
1 to 2 seconds in radio  
mode.  
During this brief sound cut-out, the RDS searches for any frequency  
permitting better reception of the station.  
With the engine off,  
the audio equipment  
switches off after a few  
minutes of use.  
When the engine is switched off, the audio equipment operating time  
depends on the battery charge.  
The switch-off is normal: the audio equipment switches to economy mode  
and switches off to prevent discharging of the vehicle's battery.  
Start the vehicle's engine to increase the battery  
charge.  
In order to protect the installation if the surrounding temperature is too  
high, the audio equipment 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.  
The message "the audio  
system is overheated"  
appears on the display.
