Changing a fuse

The three fuseboxes are located on the
dashboard on the left-hand side, in the pillar
on the right-hand side and in the engine
compartment.
The designations provided are only for the fuses
that can be replaced by the user. For any other
work, visit a CITROËN dealer or a qualified
workshop.
Professional repairers: for full information
on the fuses and relays, consult the
wiring information and diagrams available
from a CITROËN dealer.
Removing and fitting a fuse


Good
Failed
Before changing a fuse, the cause of the fault
must be found and rectified. The numbers of the
fuses are indicated on the fuse box.
Always replace a faulty fuse with a fuse of
the same rating.
CITROËN accepts no responsibility for
the cost incurred in repairing your vehicle
or for rectifying malfunctions resulting from
the installation of accessories not supplied or
not recommended by CITROËN and not
installed in accordance with its
recommendations, in particular when the
combined power consumption of all of the
additional equipment connected exceeds 10
milliamperes.

Procedure for starting the engine using another
battery or charging a discharged battery.
Lead-acid starter batteries
Batteries contain harmful substances
such as sulphuric acid and lead.
They must be disposed of in accordance
with regulations and must not, in any
circumstances, be discarded with household
waste.
Take used remote control batteries and
vehicle batteries to a special collection point.
Protect your eyes and face before
handling the battery.
All operations on the battery must be carried
out in a well ventilated area and away from
naked flames and sources of sparks, so as to
avoid the risk of explosion or fire.
Wash your hands afterwards.
Accessing the battery
The battery is located under the left-hand front
floor.


► Unscrew the 6 access flap retaining screws.
► Lift or completely remove the access flap.

In the event of a breakdown

► Tilt lever 1 downwards to release the
terminals.
► Remove terminals 2 from the negative (-)
terminal.
Wait approximately 6 minutes after
switching off the ignition before
disconnecting the battery.
Do not disconnect the terminals while the
engine is running.
Do not charge a battery without disconnecting
the terminals first.
Close the windows and the doors before
disconnecting the battery.
After reconnecting the battery, turn on the
ignition and wait 1 minute before starting the
engine, to enable the electronic systems to
initialise. If minor problems nevertheless persist
following this operation, contact a CITROËN
dealer or a qualified workshop.
It is recommended to disconnect the (-)
terminal of the battery if the vehicle is to
be left unused for more than one month.
The description of the battery charging
procedure is only indicative.
After prolonged battery disconnection, it may be
necessary to reinitialise the following functions:
– the display parameters (date, time, language,
distance and temperature units),
– the stations of the audio system,
– the central locking.
Some settings are cancelled and must be
entered once again; contact a CITROËN dealer.
If the vehicle is equipped with a tachograph or
an alarm, it is recommended that the (-) terminal
of the battery (located under the floor on the
left-hand side, in the cab) be disconnected if the
vehicle is not going to be used for more than 5
days.
Starting using another
battery
Never start the engine by connecting a
battery charger.
Never use a 24 V or higher battery booster.
Check beforehand that the backup battery
has a nominal voltage of 12 V and a capacity
at least equal to that of the discharged
battery.
The two vehicles must not be in contact with
each other.
Switch off all the electrical consumers on both
vehicles (audio system, wipers, lighting, etc.).
Make sure that the jump leads are not close
to the moving parts of the engine (fan, belt,
etc.).
Do not disconnect the (+) terminal while the
engine is running.


A. Positive metallic terminal of your vehicle
B. Backup battery
C. Earth of your vehicle
The positive metallic terminal A is accessible
through a flap located on the side of the fuse
box.
Connect only to the terminals indicated
and illustrated above. In case of
non-compliance, risk of short circuit!

Audio system
To protect the system, do not use a USB hub.
The system builds playlists (in temporary
memory); this operation can take from a
few seconds to several minutes at the first
connection.
Reduce the number of non-music files and the
number of folders to reduce the waiting time.
The playlists are updated every time the ignition
is switched off or a USB memory stick is
connected. The lists are memorised: if they are
not modified, the subsequent loading time will
be shorter.
USB socket
Located on the central console, this
socket is used only to power and
recharge the connected portable device.
Auxiliary socket (AUX)
Connect a portable device (MP3 player,
etc.) to the auxiliary jack socket using an
audio cable (not supplied).
First adjust the volume on your portable device
(to a high level). Then adjust the volume on your
audio system.
Controls are managed via the portable device.
The functions of the device connected to the
“AUX” socket are managed directly by this
device: it is therefore not possible to change the
track/folder/playlist or manipulate the playback
Radio, toggle up or down continuously: scan up/
down frequencies until you release the button.
Media, toggle up or down: select next/previous
track.
Media, toggle up or down continuously: fast
forward/rewind until you release the button.
Refuse an incoming call.
End the call in progress.
Radio
Selecting a station
The exterior environment (hills, buildings, tunnels, car parks, underground location,
etc.) may block reception, including in RDS
mode.
This behaviour is normal in the propagation of
radio waves and does not indicate any fault
with the audio system.
Press the "RADIO" button to select the
FM or AM waveband.
Briefly press one of the buttons to
automatically search for a lower/
higher frequency.
Turn the knob to manually search for a lower/higher frequency.
Press the knob to display the list of
stations received locally.
Turn the knob to select a station and press to
select it.
Memorising a station
Press the "RADIO" button to select the
FM or AM waveband.
Press the "A-B-C" button to select one of
the three memorised station levels.
Press and hold a button to memorise the
station being listened to.
The name of the station is displayed and an
audible signal confirms the memorisation.
Press "INFO" to display the information of
the station being listened to.
RDS
RDS, if displayed, allows you to continue
listening to the same station by
automatically retuning to alternative
frequencies. However, in certain conditions,
following this RDS station is not guaranteed
over the whole country, because radio
stations do not cover 100% of the area. When
the reception is weak, the frequency switches
to a regional station.
Press the "MENU" button.
Select "Regional" then press to activate
or deactivate RDS.
Alternative frequency (AF)
Select "Alternative frequency (AF)" then
press to activate or deactivate the
frequency.
When the "Regional” function is
activated, the system is therefore able to
search at any time for the best available
frequency.
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 carries 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 previously playing
media resumes at the end of the message.
Press the "MENU" button.
Select "Traffic announcement (TA)" then
press to activate or deactivate the
reception of traffic announcements.

USB socket
Insert the USB memory stick or connect
the device to the USB socket in the
central storage space , provided for transferring
data to the system, using a suitable cable (not
supplied).
