114DRIVING YOUR VEHICLE
The tow hitch must comply with the
current regulation, with reference to
Directive 94/20/EC and amendments.
Install a tow hitch which is suitable
for the towing capacity of the vehicle.
Use a unified coupling for the elec-
trical connections. The coupling is gen-
erally fitted on a specific mount fas-
tened to the tow hitch.
For electrical connection, a 7 or 13
pole 12VDC coupling must be used
(CUNA/UNI and ISO/DIN standards).
Follow the instructions provided by
the manufacturer of the vehicle and/or
the tow hitch.
Use the specific trailer light fusebox
for electrical connections.
An electric brake should be supplied
directly by the battery through a cable
with a cross section of no less than 2.5
mm
2.In addition to the electrical connec-
tion, only the lead for powering an
electric brake and the lead to power
a light inside the trailer not exceed-
ing 15W may be connected to the ve-
hicle’s electrical system.
For connections use the preset con-
trol unit with battery cable no less
than 2,5 mm
2.
FITTING DIAGRAM
The trailer tow hitch is to be fixed in
the points indicated (see diagram fig.
4).
The plate 1must have a minimum
thickness of 6 mm. The fastening
points 2will be equipped with shims
’16 x 2 mm. The tow hitch structure
is fastened in the points shown with Ø
by means of six M8 screws and four
M10 screws.
Fasten the tow hitch to the body and
trim the bumper with the frame pro-
vided with the assembly kit.
After fitting the tow hitch, the emp-
ty vehicle weight will increase by ap-
proximately 15.5 kg. The ABS system will not
control the trailer braking
system. Great care
should therefore be taken when
driving on slippery road surfaces.
Under no circumstances
modify the vehicle’s brak-
ing system for trailer
braking control. The trailer’s
braking system must be com-
pletely independent of the vehi-
cle’s hydraulic system.
TOW HITCH INSTALLATION
The towing device should be fas-
tened to the body by specialised per-
sonnel according to any additional
and/or integrative information supplied
by the Manufacturer of the device.
