Frequently asked
questions
The following information groups together the answers to the most frequently asked questions
concerning your audio system. 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: the audio system
switches to economy mode and switches off to
avoid discharging the vehicle's battery.
► Start the vehicle’
s engine to increase the charge of the battery.
The message "the audio system is
overheated" is displayed onscreen.
To protect the installation if the ambient
temperature is too high, the audio system
switches to an automatic thermal protection
mode, in which the volume may be decreased or
the CD player stopped.
► Switch the audio system off for a few minutes to allow the system to cool.
Radio
There is a difference in sound quality
between the different audio sources (radio,
CD, etc.).
For optimal listening quality, the audio settings
(Volume, Bass, Treble, Ambience and Loudness)
can be adjusted to different audio sources,
resulting in audible differences when switching
between sources (radio, CD, etc.).
► Check that the audio settings (V olume, Bass, Treble, Ambience and Loudness) are appropriate
to the sources being listened to. We recommend
setting the audio functions (Bass, Treble, Fr-Re

174
Bluetooth® audio system
balance and Le-Ri balance) to the middle
position, setting the musical ambience to "None",
setting loudness correction to "Active" in CD
mode and "Inactive" in Radio mode.
The preset stations do not function (no
sound, 87.5 MHz is displayed, etc.).
The wrong waveband is selected.
► Press the BAND button to return to the waveband (FM, FM2, DAB, AM) on which the
stations are preset.
Traffic announcement (TA) is shown but I
receive no traffic information.
The radio station is not part of the regional traffic
information network.
► Tune to a radio station that broadcasts traffic information.
The reception quality of the tuned radio
station gradually deteriorates or the station
presets are inoperative (no sound, 87.5 MHz
is displayed, etc.).
The vehicle is too far from the selected station’s
transmitter, or no transmitter is present in the
geographical area.
► Activate the RDS function to allow the system to check for a more powerful transmitter in the
area.
The environment (hills, buildings, tunnels,
basement car parks, etc.) may block reception,
including in RDS mode.
This is a perfectly normal phenomenon, and is
not indicative of an audio system malfunction.The aerial is absent or has been damaged (for
example when going through an automatic car
wash or in an underground car park).
► Have the aerial checked by a dealer
.The sound intermittently cuts out for 1 or 2
seconds in radio mode.
During this brief sound cut-out, the RDS
searches for another frequency giving better
reception of the station.
► Switch off the RDS function if the phenomenon occurs too frequently and always
on the same route.
Media
The Bluetooth connection is cut.
The battery in the peripheral device may not be
sufficiently charged.
► Charge the battery in the peripheral device.The message "USB device error" is displayed
in the screen.
The USB stick has not been recognised, or may
be corrupted.
► Reformat the USB memory stick.
The CD is systematically ejected or is not
played.
The CD is upside down, cannot be read, does
not contain audio files or contains audio files of a
format not recognised by the audio system.
The CD is protected by an anti-pirating system
not recognised by the audio system.
► 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 badly damaged.► Check the content in the case of a burned CD: read the recommendations in the "Audio"
section.
Due to poor quality, certain burned CDs will not
be played by the audio system.
The CD audio quality is is poor.
The CD is scratched or of poor quality.
► Insert good quality CDs and store them in suitable conditions.
The audio settings (bass, treble, ambience) are
unsuitable.
► Return bass and treble settings to 0, without selecting an ambience.
I am unable to play the music files on my
smartphone via the USB port.
Depending on the smartphone, access by the
audio system to music on the smartphone may
have to be approved on the latter.
► Manually activate the MTP profile on the smartphone (USB settings menu).
Telephone
I am unable to access my voicemail.
Few telephones or service providers allow the
use of this function.
► Call your voicemail, via the telephone menu, using the number provided by your operator.
