Practical information
If the AdBlue® tank is completely empty
– which is confirmed by the message
"Top up AdBlue: Starting impossible" – it is
essential to add at least 5 litres.
After refilling
► Refit the blue cap to the tank filler and turn it
clockwise as far as it will go (one sixth of a turn).
► Close the fuel filler flap.
Do not dispose of AdBlue® containers in
the household waste.
Place them in a container reserved for this
purpose or take them back to where you
bought them.
Never store AdBlue® containers in your
vehicle.
Precautions for use
AdBlue® is a urea-based solution. This fluid is
non-flammable, colourless and odourless (when
kept in a cool place).
In the event of contact with the skin, wash the
affected area with soap and running water. In the
event of contact with the eyes, immediately rinse
the eyes with large amounts of water or with an
eye wash solution for at least 15 minutes. Seek
medical attention if you feel a persistent burning
sensation or irritation.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.
In certain conditions (high temperature, for
example), the risk of release of ammonia cannot
be excluded: do not inhale the fluid. Ammonia
vapours have an irritant effect on mucous
membranes (eyes, nose and throat).
Store AdBlue® out of the reach of
children, in its original container.
Procedure
Before starting the top-up procedure, ensure that
the vehicle is parked on a flat and level surface.
In wintry conditions, ensure that the temperature
of the vehicle is above -11 °C. Otherwise the
AdBlue
® may be frozen and so cannot be poured
into its tank. Park the vehicle in a warmer area
for a few hours to allow the top-up to be carried
out.
Never put the AdBlue® into the Diesel
fuel tank.
If any AdBlue® is splashed, or if there are
any spillages on the bodywork, rinse
immediately with cold water or wipe with a
damp cloth.
If the fluid has crystallised, clean it off using a
sponge and hot water.
Important: in the event of a top-up after
an AdBlue breakdown, you must wait
about 5 minutes before switching on the
ignition, without opening the driver's door,
unlocking the vehicle or bringing the
electronic key into the passenger
compartment.
Switch on the ignition, then wait for 10
seconds before starting the engine.
► Switch off the ignition and remove the key
from the switch to switch off the engine.


► Turn the blue cap of the AdBlue® tank a 6th of
a turn anti-clockwise and remove it.
Filling up
► With a container of AdBlue®: after checking
the expiry date, read the instructions on the
label carefully before pouring the contents of the
container into the vehicle's AdBlue tank.
► With an AdBlue
® pump: introduce the nozzle
and fill the tank until the nozzle automatically
cuts out.
In order not to overfill the AdBlue® tank:
– Add between 10 and 13 litres using
AdBlue
® containers.
– Stop after the nozzle’s first automatic cut-
out, if you are refilling at a service station.
The system only registers AdBlue
® top-ups of
5 litres or more.

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
off, there is no longer braking and steering
assistance.
A professional towing service must be
called if:
– Broken down on a motorway or main road.
– Not possible to put the gearbox into neutral,
unlock the steering, or release the parking
brake.
– Not possible to tow a vehicle with an
automatic gearbox, with the engine running.
– Towing with only two wheels on the ground.
– Four-wheel drive vehicle.
– No approved towbar available.
Towing your vehicle
The removable towing eye is located in the tool
box under the front passenger seat.
► Unclip the cover using a flat tool.


► Screw the removable towing eye in fully.
► Attach the approved towbar to the removable
towing eye.
► Place the gear lever in neutral.

Special features

– Never work under a tipper body that is not
supported,
– Switch off the power supply to the electro-
hydraulic unit using the circuit breaker,
– Vehicle stationary, engine off.
For safety reasons, we very strongly
advise against doing anything under the
tipper body while it is being operated or while
it is being serviced.
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.
► Using a wide screwdriver, unscrew the banjo
bolt/piston assembly.
► Check that the piston slides freely and
remove any foreign bodies. Use a magnet to
remove any metal filings.
► Refit the assembly and make sure that the
piston slides freely. Retain the ball with a little
grease on the cap for refitting.
► Bleed the hydraulic unit.
Bleeding the hydraulic unit
► Unscrew hexagonal cap 257.
► Loosen internal screw 587 by half a turn,
using a 6 mm hex key.
► Operate the unit for a few seconds by
pressing the raise button.
The tipper truck does not rise or rises very
slowly. When the oil exits through this opening,
the unit is bled.
► Retighten screw 587 and replace cap 257.
