RADIO  
SELECTING A STATION  
The exterior environment (hills, buildings, tunnel, car park, below  
ground…) may prevent reception, even in RDS station tracking  
mode. This phenomenon is normal in the propagation of radio  
waves and is in no way indicative of a fault with the audio system.

RDS  
RECEIVING TA MESSAGES  
The TA (TrafÞc Announcement) function gives priority to TA alert  
messages. To operate, this function needs good reception of a  
radio station transmitting this type of message. When a trafÞc  
report is transmitted, the current audio source (Radio, CD,  
USB, …) is interrupted automatically to play the TA message.  
Normal playback of the audio source resumes at the end of the  
transmission of the message.  
RDS, if displayed, enables you to continue listening to the same  
station by automatic retuning to alternative frequencies. However,  
in certain conditions, coverage of an RDS station may not be  
assured throughout the country as radio stations do not cover  
100 % of the territory. This explains the loss of reception of the  
station during a journey.

transmits this type of message. When a message is transmitted,  
the current audio source (Radio, CD, USB, …) is interrupted  
automatically to receive the INFO message. Normal play  
resumes at the end of the message transmission.

INFORMATION AND ADVICE  
On a single disc, the CD player can read up to 255 MP3 Þles spread  
over 8 directory levels. However, it is recommended that this be kept  
to 2 levels so as to limit the time taken to access and play the CD.  
The audio system will only play Þles with extension ".mp3" or ".wma"  
and a compression rate that is constant or variable between 32 Kbps  
and 320 Kbps.  
During play, the folder structure is not observed.  
In order to be able to play a recorded CDR or CDRW, when recording  
it is preferable to select standards ISO 9660 level 1.2 or Joliet.  
If the disc is recorded in another format, it may not be played correctly.  
It is advisable to restrict Þle names to 20 characters without using  
special characters (e.g. " ? ; ù) to avoid any playing or displaying  
problems.  
It is recommended that the same recording standard is always used  
for an individual disc, with as low a speed as possible (4x maximum)  
for optimum sound quality.  
In the particular case of a multi-session CD, the Joliet standard is  
recommended.  
The playlists accepted are types .m3u and .pls.  
Do not connect a hard disk or USB device other than audio players to  
the USB port. This may cause damage to your installation.  
The number of Þles is limited to 5 000 in 500 directories on a  
maximum of 8 levels.

A FEW DEFINITIONS  
Each press of the button, located at the end of the  
wiper stalk, displays the different trip computer  
information in succession, depending on the screen.  
Range: displays the distance which can travelled with the remaining fuel  
detected in the tank, based on the average fuel consumption over the last  
few miles (kilometres).  
This displayed value may vary signiÞcantly following a change in  
the vehicle speed or the relief of the route.  
When the range falls below 20 miles (30 km), dashes are displayed.  
After Þlling with at least 5 litres of fuel, the range is recalculated and is  
displayed when it exceeds 60 miles (100 km).  
If, whilst driving, dashes are displayed continuously in place of the digits,

the different audio  
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…).  
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  
Fader, 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.  
sources (radio, CD…).  
When changing the  
settings for treble and  
bass, the ambience  
setting is deselected.  
Choosing an ambience imposes settings for treble and bass. Modifying  
one without the other is not possible.  
Modify the treble and bass settings or the  
ambience setting to obtain the desired sound  
quality.  
When changing the  
ambience setting, treble  
and bass are reset to  
zero.  
When changing the  
balance setting,  
distribution is deselected.  
Choosing a distribution setting imposes a balance setting. Modifying one  
without the other is not possible.  
Modify the balance setting or the distribution  
setting to obtain the desired sound quality.
