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.

121
In the event of a breakdown
8

► 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).

Maintenance
Reservoir
Regularly check and top up the engine oil level.
Change the oil once a year. If the oil contains
water, change it.
Regularly check the condition of the hose and
ensure the hydraulic system is properly sealed.
Pump and motor
No servicing required. The rolling elements are
permanently lubricated and the bearings are
lubricated by the pumped oil.
Lubrication
The pins of the tipper truck and the ram do not
contain lubricant. Regularly lubricate the hinges
and the grab handles of the side boards as well
as the retaining hooks of the rear board.
Sub-frame and tipper truck
For maximum service life, you are advised to
maintain your tipper truck by regularly washing it
using a power washer.
Carry out any required paint touch-ups quickly to
prevent the spread of rust.
After 8 months of use, check the tightening torque of the connection
between the chassis and the underbody (in
accordance with the manufacturer's
bodybuilding recommendations).
Cleaning the slide valve
► Loosen cap 244A, taking care with the ball
and retrieving it.
