TOWING A
TRAILER
GENERAL NOTES
The car must be fitted with a
homologated tow hitch and suitable
electrical system for towing a cara-
van or a trailer. Have the tow hitch
fitted by an expert who will issue
specific documentation for use on
roads.
Fit special and/or additional
rearview mirrors in accordance with
the highway code.
Remember that towing a trailer
makes it harder for the car to climb
the maximum gradients specified,
increases braking and overtaking
distance, proportionally to the over-
all weight of the trailer.Engage a low gear when driving
downhill rather than constantly
braking.
The weight the trailer exerts on the
car’s tow hitch coupling reduces the
car’s loading capacity by the same
amount. In order to be sure you are
not exceeding the maximum towing
weight (as specified in the registra-
tion book), you have to take into
account the trailer’s fully laden
weight, including accessories and
personal luggage.
Do not exceed the speed limits for
towing a trailer in the country you
are driving in. In any case, do not
exceed the top speed of 100 km/h.
Trailer electrical connection shall
only be performed with ignition key
at STOPor removed.
When trailer electrical connection
is on and you switch on the rear fog
lights, only the trailer rear fog lights
will come on.The ABS system will not
control the trailing brak-
ing system. Great care
should therefore be taken when
driving on slippery road surfaces.
Under no circumstances
modify the car’s braking
system for trailer braking
control. The trailer’s braking sys-
tem must be completely indepen-
dent of the car’s hydraulic sys-
tem.
The rear parking sensors
are automatically deacti-
vated when the plug of the
trailer’s electrical cable is insert-
ed in the car’s tow hitch socket.
The rear sensors activate auto-
matically when the trailer’s plug is
disconnected.

265
TOW HITCH INSTALLATION
The tow hitch must be fixed to the
body by an expert in accordance
with the following instructions and
respecting the additional and/or
integrative information provided by
the tow hitch manufacturer.
The tow hitch to be fitted must
comply with the current regulations
in force, with reference to Directive
94/20/EEC and subsequent modifi-
cations.
Use a tow hitch suited for the max-
imum towable load of the car ver-
sion on which the tow hitch is to be
fitted.
Use a unified coupling for the elec-
trical connections. The coupling is
generally fitted on a specific mount
fastened to the tow hitch. A specific
trailer lights control unit shall be
installed on the car.For the electric connections, a 7
pole 12VDC coupling must be used
(CUNA/UNI and ISO/DIN stan-
dards). Follow the instructions pro-
vided by the manufacturer of the car
and/or the tow hitch.
The electrical brake (where rele-
vant) or other device (electrical
winch, etc.) must be powered direct-
ly from the battery by means of a
lead with a cross-section area no
smaller than 2.5 mm
2.
IMPORTANTUse the electrical
brake or winch only when the engine
is running.
In addition to the electrical connec-
tions, only the power wire for an
additional electrical brake and for
internal trailer lighting with a power
not exceeding 15W can be connect-
ed to the car’s electrical system.
For connections use the specific
control unit with battery cable not
less than 2.5 mm
2.INSTALLATION DIAGRAM (fig. 1)
Fasten the tow hitch in the points
marked with (1) using 18 M10
screws and, in the points marked
with (2) use four M8 screws.
Fasten the tow hitch to the body
avoiding any type of drilling and
trimming of the rear bumpers that
remains visible when the tow hitch is
removed.
IMPORTANTFasten a tag in a
clearly visible position at the same
height as the tow hitch. The tag is
compulsory. It must be adequately
sized, made of suitable material and
carry the following information:
MAX LOAD ON BALL COUPLING
75 kg.
After assembly, seal the fastening
screws holes to prevent exhaust fumes
from entering the passenger compart-
ment.

WINTER TYRES
These tyres have been specifically
designed for use on snow and ice
and should be fitted in place of the
existing tyres.
Use only the homologated tyres
listed in log book.
Lancia Dealershipswill be glad
to provide advice on the most suit-
able type of tyres according to your
needs.
For information on the tyres to be
fitted, inflation pressure and winter
tyre specifications, follow the pre-
scriptions given in “Technical speci-
fications”.
The performance of winter tyres is
greatly reduced when the tread
depth is less than 4mm. In this situ-
ation it would be safer to have them
replaced.Due to winter tyre features, under
normal conditions of use or on long
motorway journeys, the perfor-
mance of these tyres is lower than
that of standard tyres.
The use of these tyres should there-
fore be limited to the conditions for
which they were designed and certi-
fied.
IMPORTANT When using winter
tyres with a maximum speed index
below the one that can be reached
by the car (increased by 5%), place
a suitable notice in the passenger
compartment to inform the driver of
the top speed at which the winter
tyre can run (as per EC Directive).All four tyres should be the same
(brand and track), to ensure greater
safety when driving, braking and
cornering.
Remember that it is inappropriate
to change the direction of rotation of
tyres.
The maximum speed for winter
tyres with “Q” marking is 160
km/h, with “T” marking is 190
km/h, whereas with “H” marking is
210 km/h. Always respect the high-
way code speed limit.

268
Snow chains cannot be
fitted on 225/50R17 (94W),
225/50ZR17 (94W) and
245/40ZR18 tyres, since they
interfere with the front suspension.Keep your speed
down when snow
chains are fitted.
Do not exceed 50 km/h. Avoid
potholes, steps and pavements
and do not drive for long dis-
tances on roads not covered with
snow to prevent damaging the car
and the roadbed.
Disconnect the ASR sys-
tem when snow chains
are fitted. Press the ASR-
OFF button: button led on.
SNOW CHAINS
The use of snow chains is regulated
by the legislation in force in the
country the car is driven in.
Snow chains must only be applied
to the driving wheels (front wheels).

USING THE CAR AGAIN
Before using the car again after a
prolonged period of inactivity, the
following operations are recom-
mended:
– Do not dry-dust the car body.
– Check for fluid leaks (oil, brake
and clutch fluid, engine coolant
etc.).
– Change engine oil and filter.
– Check the level of:
– brake and clutch fluid
– engine coolant.
– Check the air cleaner and change
it, if required.
– Check the tyre pressure and the
tyres for signs of damage, cuts or
cracks. If this is the case, have them
replaced.
– Check the engine belt conditions.STORING THE CAR
The following precautions should
be taken if the car will not be used
for several months:
– Park the car in covered, dry and
if possible well-ventilated premises.
– Engage a gear.
– If the car is parked on flat
ground, disengage the electric park-
ing brake as described in the rele-
vant paragraph.
– Clean and protect the painted
parts using protective wax.
– Sprinkle talcum powder on the
rubber windscreen and rear window
wiper blades and lift them off the
glass.
– Slightly open the windows.
– Inflate the tyres to 0.5 bar above
the normal specified pressure, lean
them on wood boards, if possible
and check it at intervals.– Do not switch the electronic
alarm system on.
– Remove the negative cable (-)
from the battery terminal and check
the battery charge. This check
should be performed every month if
the car is to be stored for long peri-
ods. Recharge the battery if it falls
below 12.5V.
IMPORTANT Before opening the
luggage compartment bonnet to dis-
connect the battery, carefully read
and comply with instructions con-
tained in the paragraph “If battery is
to be disconnected” in the chapter
“In an emergency”.
– Do not drain the engine cooling
system.
– Cover the car with a cloth or per-
forated plastic sheet. Do not use
sheets of non-perforated plastic as
they do not allow moisture on the
body to evaporate.

– Reconnect the negative battery
terminal (-) after checking the bat-
tery charge.
IMPORTANT Before connecting
the battery again carefully read and
comply with instructions contained
in the paragraph “If battery is to be
disconnected” in the chapter “In an
emergency”.
– With the gear lever to neutral,
start the engine and let it idle a few
minutes, pressing the clutch pedal
repeatedly.
This operation must be
carried out outdoor.
Exhaust gas contains car-
bon monoxide, an extremely
toxic gas.USEFUL

EMERGENCY
START-UP
If the Lancia CODE system cannot
deactivate the engine immobilising
system, symbols Yand Uwill
remain lit on the multifunction dis-
play together with messages
“ELECTRONIC KEY NOT
RECOGNISED” and “ENGINE
CONTROL SYSTEM FAULT”, and
the engine will not start. Follow the
emergency start-up procedure to
start the engine.
Read the whole procedure care-
fully before trying to carry it out.
If you make a mistake in the emer-
gency procedure you must turn the
ignition key back to STOP and
repeat the whole operation from the
beginning (step 1).
1) Read the five-digit electronic
code on the CODE card.
2) Turn the ignition key to MAR.3) Press and hold down the accel-
erator pedal. The warning light U
on the instrument panel will light up
for about 8 seconds, and then go
out. At this point release the acceler-
ator pedal and get ready to count the
flashes of the warning light U.
4) Count the number of flashes
that corresponds to the first figure of
the code on the CODE card, then
press the accelerator pedal and keep
it down until the Uwarning light
comes on for four seconds and then
goes out. Release the accelerator
pedal.
5) The Uwarning light will start
flashing again: after it has flashed
the number of times that corre-
sponds to the second figure on the
CODE card, press the accelerator
pedal to the floor and keep it there.
6) Do the same for the remaining
digits on the CODE card.7) Once the final figure has been
entered, keep the accelerator pedal
pressed. The Uwarning light will
light up for 4 seconds and then go
out. Release the accelerator pedal.
8) The Uwarning light will flash
rapidly for about 4 seconds to indi-
cate that the operation has been
completed correctly.
9) Start the engine by turning the
ignition key from MARto AVV
(without turning it to STOP).
If, however, warning light Ustays
on, turn the ignition key to STOP
and repeat the procedure from step
1).
IMPORTANTAfter an emergency
start, you should contact a Lancia
Dealershipimmediately as you will
have to repeat the procedure
described each time you want to
start the engine.
