► 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!

122
In the event of a breakdown
► Connect the red cable to metallic terminal A,
then to the (+) terminal of backup battery B.
► Connect one end of the green or black cable
to the negative (-) terminal of backup battery B.
► Connect the other end of the green or black
cable to earth point C of your vehicle.
► Operate the starter, let the engine run.
► Wait for the engine to return to idle and
disconnect the cables.
Charging the battery using a
battery charger
► Access the battery, located in the left-hand
front floor.
► Disconnect the battery.
► Follow the instructions for use provided by
the manufacturer of the charger.
► Reconnect starting with the (-) terminal.
► Check the cleanliness of the terminals. If they
are covered with sulphate (whitish or greenish
deposit), remove and clean them.
The charging operation must be carried out in a well-ventilated area and away
from naked flames and any sources of sparks
so as to avoid the risk of explosion or fire.
Do not try to recharge a frozen battery: it
must first be thawed to avoid the risk of
explosion. If it has frozen, before charging it,
have the battery checked by a specialist who
will check that the interior components have
not been damaged and that the container is
not cracked, which would involve a risk of
leakage of toxic and corrosive acid.
Perform a slow charge at low amperage for
about 24 hours maximum to avoid damaging
the battery.
The presence of this label, in particular with the Stop & Start system, indicates
the use of a 12 V lead-acid battery with
special technology and specification; the
involvement of a CITROËN dealer or a
qualified workshop is essential when
replacing or disconnecting the battery.
After refitting the battery at a CITROËN dealer or a qualified workshop, the Stop
& Start system will only be active after a
continuous period of immobilisation of the
vehicle, a period which depends on the
climatic conditions and the state of charge of
the battery (up to about 8 hours).
Towing
General recommendations
Observe the legislation in force in the
country where you are driving.
Ensure that the weight of the towing vehicle is
higher than that of the towed vehicle.
The driver must remain at the wheel of the
towed vehicle and must have a valid driving
licence.
When towing a vehicle with all four wheels on
the ground, always use an approved towing
arm; rope and straps are prohibited.
The towing vehicle must move off gently.
When the vehicle is towed with its engine

Special features
10Tipper truck

The lifting of the tipper is provided by a hydro-
electric unit powered by the vehicle's battery.


The ascent or descent is done by holding the
corresponding buttons of the magnetic and
removable remote control located on a support
inside the cab.
The lifting of the tipper is powered by unit's
motor.
The descent is powered by a solenoid valve
opening the strut's oil return.
An anti-drop system makes the descent of the
tipper safe whether static or lifting.
Safety recommendations

Never drive with the tail board down.
Ensure that there are no people or
obstacles present (on the ground and higher
up) when unloading.
Never leave the tipper raised when not in use.
Always tip with the upper part of the rear tail
board locked.
Observe the payload on the tare plate on the
vehicle.
Regularly check that the suspensions are in
good condition and that the tyres are inflated
to the recommended pressure.
Spread the load evenly in the tipper.
Transport homogeneous products which flow
easily.
Never drive, even slowly, with the tipper
raised.
Tip on a flat and hard surface: sloping or loose ground can cause a displacement
of the centre of gravity which affects the stability
of the whole unit.

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
