Roof-mounted carrying
systems


For safety reasons and to avoid damaging the
roof, it is imperative to use a carrying system
(roof bars or roof rack) approved for the vehicle.
Roof bars can only be fitted on H1 or H2 height
versions of vans, combis and minibuses. On
minibuses, check the presence of a roof air
conditioning unit.
The carrying device must be fixed to the
anchorage points on the roof of the vehicle: 6,
8 or 10, depending on the wheelbase of the
vehicle.
Observe the fitting instructions and the
conditions of use in the guide supplied with the
carrying device.
Maximum roof load, evenly distributed:
150 kg, for all versions, within the limits
of the gross vehicle weight (GVW).
Roofs cannot be equipped with a
carrying system on H3 height versions.
Strictly observe the legal provisions in
force concerning the maximum volume
measurements.
For more information on the Technical
data of the vehicle, and in particular on
the dimensions, refer to the corresponding
section.
Bonnet
Opening
Before doing anything under the bonnet,
deactivate the Stop & Start system to
avoid the risk of injury related to an automatic
change to START mode.
On the inside
This operation must only be done with the
vehicle stationary and the driver’s door open.

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.

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.
Check that the tipper truck lowers correctly.

Audio system
Voice commands
Information - Using the
system
Instead of touching the screen, you can
use your voice to control the system.
To ensure that voice commands are always recognised by the system, please
observe the following recommendations:
– speak in a normal tone of voice,
– before speaking, always wait for the "beep"
(acoustic signal),
– the system is able to recognise the voice
commands provided, regardless of gender,
tone and inflection of the voice of the speaker,
– if possible, minimise the noise inside the
passenger compartment,
– before issuing a voice command, ask any
other passengers to refrain from speaking.
Since the system recognises commands
regardless of who is speaking, when several
people are speaking simultaneously, it
is possible for the system to recognise
commands that are different or additional to
what has been requested,
– for optimal operation, you are advised to
close the windows and any sunroof present
(on versions/markets where fitted) to avoid
any external source of disturbance.
