USB sockets
These symbols determine the type of use of a USB socket:
Power supply and recharging.
Likewise, plus exchange of multimedia
data with the audio system.


USB sockets allow the connection of a portable
device.
The USB socket located at the front on the left-hand side also
allows a smartphone to be connected by Android
Auto® or CarPlay®, enabling certain smartphone
applications to be used on the touch screen.
For best results, use a cable made or approved
by the device manufacturer.
These applications can be managed using the
steering-mounted controls or the audio system
controls.
When the USB socket is used, the
portable device charges automatically.
While charging, a message is displayed if the
power drawn by the portable device exceeds
the current supplied by the vehicle.
For more information about how to use this
equipment, refer to the sections describing
the audio and telematics systems.
12 V accessory socket



► Plug in a 12 V accessory (with a maximum
rated power of 120 W) using a suitable adapter.
Observe the maximum power rating to
avoid damaging the accessory.
The connection of an electrical device not approved by CITROËN, such as a
USB charger, may adversely affect the
operation of vehicle electrical systems,
causing faults such as poor radio reception or
interference with displays in the screens.
Wireless smartphone
charger




This system allows wireless charging of a
portable device such as a smartphone, using the
magnetic induction principle, in accordance with
the Qi 1.1 standard.
The portable device to be charged must be
compatible with the Qi standard, either by design
or by using a compatible holder or shell.
A mat can also be used provided that it is
approved by the Manufacturer.
The charging area is identified by the Qi symbol.
The charger works with the engine running and
with the Stop & Start system in STOP mode.
Charging is managed by the smartphone.

on equipment.
Selecting a station
Press one of the buttons for an automatic
search for radio stations.
Or
Press on the displayed frequency.
Enter the FM and AM waveband values
using the virtual keypad.
Or
Press this button to display the list of
stations received and available on the

Radio reception may be affected by the
use of electrical equipment not approved
by the Brand, such as a USB charger
connected to the 12 V socket.
The exterior environment (hills, buildings,
tunnels, basement car parks, etc.) may block
reception, including in RDS mode. This
behaviour is normal in propagation of radio
waves and does not indicate any failure of the
audio system.
Presetting a station
Select a radio station or frequency.Press the "Presets " button.
Make a long press on an empty line to preset the
station. An audible signal confirms the presetting
of the station.
It is possible to preset up to 16
stations.
To replace a preset station by the currently playing station, make a long
press on the preset station.
Activating/Deactivating RDS
RDS, if activated, allows you to continue
listening to the same station by automatically
retuning to alternative frequencies.
In certain conditions, tracking may not be
assured throughout the entire country as
radio stations do not cover 100% of the
territory. This explains the loss of reception of
the station during a journey.
Press the "Radio Settings " button.
Activate/Deactivate "RDS options".
Playing TA messages
The TA (Traffic Announcement) function gives
priority to TA alert messages.
To operate, this function needs good reception
of a radio station that transmits this type of
message. While traffic information is being
broadcast, the current media is automatically
interrupted so that the TA message can be
heard. Normal play of the media previously
playing is resumed at the end of the message.
Press the "Radio Settings" button.
Activate/Deactivate "Traffic
announcement (TA)".
Audio settings
Press the "Radio Settings " button.
In the list, select "Audio Settings ".
Activate/deactivate and configure the available
options (sound balance, ambiances, etc.).
The sound balance/distribution is audio processing that allows the quality of the

Press the "SOURCE" button.
In the list of available sources, choose " DAB
Radio".
Activating FM-DAB Tracking
"DAB" does not cover 100% of the territory.
When the digital radio signal is poor, the
"FM-DAB tracking" allows you to continue
listening to the same station, by automatically
switching to the corresponding "FM" analogue
station (if there is one).
Press the "Radio Settings " button.
Activate "DAB-FM".
If "FM-DAB tracking" is activated, there
may be a difference of a few seconds
when the system switches to "FM" analogue
radio with sometimes a variation in volume.
Once the digital signal quality is restored, the
system automatically changes back to "DAB".
If the "DAB" station being listened to is
not available on "FM", or if the "FM-DAB
tracking" is not activated, the sound will cut
out while the digital signal is too weak.

The system builds playlists (in temporary
memory); this operation can take from a
few seconds to several minutes at the first
connection. Playlists are updated whenever a USB memory
stick is connected or the contents of a particular
USB memory stick are changed. The lists
are memorised: if they are not modified, the
subsequent loading time will be shorter.
