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.
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.
Telephone

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).
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
start/end/pause using the controls on the control
panel or the steering wheel.
Do not leave the cable of your portable device
connected to the “AUX” socket when not in use,
to avoid possible noise from the speakers.
Selecting the source

Select the "Source" tab to show the
rolling display of audio sources.
Select the source.
Use the play settings on the screen.
Press the "Rand." button and/or the
"Repeat" button to activate them, press again to
deactivate them.

The audio system will only play audio files with
".wav", ".wma" and ".mp3" file extensions, at bit
rates between 32 Kbps and 320 Kbps.
For audio files with ".aac", ".m4a", ".m4b" and
".mp4" file extensions, the supported sampling
rates are 8 - 96 kHz.
".m3u" and ".wpl" types are also supported.
The system does not manage devices with a
capacity greater than 64 GB.
It is advisable to restrict file names to 20
characters, without using special characters (e.g.
" " ? . ; ù) so as to avoid any reading or display
problems.
The system supports USB mass storage devices, BlackBerry® devices or Apple®
players via the USB sockets. The adapter
cable is not supplied.
Devices are managed using the audio system
controls.
Other devices, not recognised by the system
during connection, must be connected to
the auxiliary socket using a Jack cable (not
supplied).
Only use USB memory sticks formatted to FAT
32 (File Allocation Table).
To protect the system, do not use a USB hub.
The system does not support the simultaneous connection of two identical
devices (two memory sticks or two
Apple
® players) but it is possible to connect
one memory stick and one Apple® player at
the same time.
It is recommended that you use genuine
Apple® USB cables to guarantee correct
operation.

phone is registered as the favourite (the mobile
phone will have priority over other mobile
phones, which may be registered later).
– if no other device is associated, the system
considers the first associated device as the
favourite.
For mobile phones that are not set as
favourites, priority is determined by the
connection order. The last phone
connected will have the highest priority.
The services available depend on the
network, the SIM card and the compatibility
of the Bluetooth
® devices used. Refer to your
telephone’s user guide and your service provider
to check which services you are able to access.
When you return to the vehicle, the last
phone connected reconnects automatically,
within approximately 30 seconds of switching the
ignition on (with Bluetooth
® activated).
To change the automatic connection profile,
select the phone from the list then select the
desired parameters.
The profiles compatible with the system are:
HFP, OPP, PBAP, A2DP, AVRCP, MAP.
Automatic reconnection
When the ignition is switched on, the telephone
connected when the ignition was last switched
off reconnects automatically, if this connection
mode had been set during the pairing procedure
(see previous pages).
The connection is confirmed by the display of a
message and the name of the telephone.
