12The "Danger zone" audible warning feature is
not working.
The audible warning is not active or the volume
is too low.
► Activate the audible warning in the "Navigation" menu and check the voice volume
in the sound settings.
The system does not suggest a detour
around an incident on the route.
The route settings do not take account of TMC
messages.
► Configure the "Traffic info " function in the route settings list (Without, Manual or
Automatic).
I receive a warning about a "Danger area"
that is not on my route.
As well as providing guided navigation, the
system announces all "Danger areas" positioned
in a cone located in front of the vehicle. It may
provide an alert for "Danger areas" located on
nearby or parallel roads.
► Zoom the map to show the exact location of the "Danger area". You can select "On the
route" to stop receiving warnings or decrease the
warning duration.
Certain traffic jams along the route are not
indicated in real time.
On starting, a few minutes may elapse before
the system begins to receive traffic information.
► Wait until traffic information is being received correctly (traffic information icons shown on the
map). In certain countries, only major routes
(motorways, etc.) are listed for the traffic
information.
This is perfectly normal. The system is
dependent on the traffic information available.
The altitude is not displayed.
On starting, GPS initialisation may take up to
3 minutes to receive more than 4 satellites
correctly.
► Wait until the system has started up completely so that there is GPS coverage by at least 4 satellites.Depending on the geographical environment
(tunnel, etc.) or the weather, the conditions of
reception of the GPS signal may vary.
This behaviour is normal. The system is
dependent on the GPS signal reception
conditions.
My navigation is no longer connected.
During start-up and in certain geographical
areas, the connection may be unavailable.
► Check that the online services are activated (settings, contract).
Radio
The reception quality of the tuned radio
station gradually deteriorates or the station
presets are not working (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 by means of the short-cut menu to enable the system to check
whether there is a more powerful transmitter in
the geographical area.
The aerial is missing or has been damaged
(for example while entering a car wash or
underground car park).
► Have the aerial checked by a dealer
.The environment (hills, buildings, tunnels,
basement car parks, etc.) is blocking reception,
including in RDS mode.
This is a perfectly normal phenomenon, and is
not indicative of an audio system malfunction.
I cannot find some radio stations in the list of
stations received.
The name of the radio station changes.
The station is no longer received or its name has
changed in the list.
Some radio stations send other information
in place of their name (the title of the song for
example).
The system interprets these details as the station
name.
► Press the "Update list" button in the "Radio stations” secondary menu.
Media
Playback of my USB memory stick starts only
after a very long wait (around 2 to 3 minutes).
Some files supplied with the memory stick may
greatly slow down access to reading the memory
stick (multiplication by 10 of the cataloguing
time).

► Delete the files supplied with the memory stick and limit the number of sub-folders in the
file structure on the 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.
► 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.
The CD has been burned in a format that is not
compatible with the player (udf, etc.).
► Check the content if it is a burned CD: consult the advice in the "AUDIO" section.► The audio system CD player does not play DVDs.
The CD is protected by an anti-pirating system
not recognised by the audio system.
► Due to poor quality, certain burned CDs will not be played by the audio system.
There is a long waiting period following the
insertion of a CD or connection of a USB
memory stick.
The system reads a variety of data (folder, title,
artist, etc.). This can take from a few seconds to
a few minutes.
This is perfectly normal.
The CD audio quality 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.
Some characters in the information about
the media currently being played are not displayed correctly.
The audio system is unable to process certain
types of character.
► Use standard characters to name tracks and folders.
Playback of files in audio streaming mode
does not start.
The connected device does not automatically
start playback.
► Start playback from the device.The names of tracks and playing times
are not displayed on the screen in audio
streaming mode.
The Bluetooth profile does not allow the transfer
of this information.
Telephone
I cannot connect my Bluetooth telephone.
The telephone's Bluetooth function may be
switched off or the telephone may not be visible.
► Check that the telephone has Bluetooth switched on.► Check in the telephone settings that it is "visible to all".► Deactivate then reactivate the telphone’
s Bluetooth function. The Bluetooth telephone is not compatible with
the system.
► You can check that your telephone is compatible on the Brand's website (services).
The volume of the telephone connected in
Bluetooth mode is inaudible.
The volume depends on both the system and the
telephone.
► Increase the volume of the audio system, to maximum if required, and increase the volume of
the telephone if necessary.
Ambient noise affects the quality of the
telephone call.
► Reduce the ambient noise level (close windows, reduce ventilation, slow down, etc.).
Some contacts are duplicated in the list.
The options for synchronising contacts are:
synchronise the contacts on the SIM card, the
contacts on the telephone, or both. When both
synchronisations are selected, some contacts
may be duplicated.
► Select "Display SIM card contacts" or "Display telephone contacts".
The contacts are not listed in alphabetical
order.
Some telephones offer display options.
Depending on the settings chosen, contacts can
be transferred in a specific order.
► Modify the telephone directory display settings.
The system does not receive SMS.
SMS text messages cannot be sent to the
system in Bluetooth mode.
Settings
When the treble and bass settings are
changed, the ambience is deselected.
When the ambience is changed, the treble
and bass settings are reset.
Selecting an ambience imposes the treble and
bass settings, and vice versa.
►
Modify the treble and bass or ambience settings to obtain the desired musical ambience.
When the balance settings are changed, the
distribution is deselected.
When the distribution setting is changed, the
balance settings are deselected.
Selecting a distribution setting imposes the
balance settings, and vice versa.
► Modify the balance setting or the distribution setting to obtain the desired sound quality.
There is a difference in sound quality
between audio sources.
To allow for optimal listening quality, the sound
settings can be tailored to different audio
sources, which can generate audible differences
when changing source.
► Check that the sound settings are appropriate to the sources listened to. We recommend
setting the sound functions (Bass:, Treble:,
Balance) to the middle position, setting the
musical ambience to "None", setting loudness
correction to "Active" in USB mode and "Inactive"
in Radio mode.
► In all cases, after applying sound settings, adjust the volume level on the portable device (to
