Obstacles placed in side areas are
detected at a distance of less than
0.6 m.
Rear sensors are automatically
switched on by removing the trailer
cable plug.FAULT INDICATIONS
The system control unit checks all
the system components every time
the ignition key is turned to MAR.
Then, the sensors and their respec-
tive electrical connections are con-
stantly monitored during system
operation.
Parking assist system faults are sig-
nalled by the lighting of symbol t
on the multifunction display, togeth-
er with message “PARKING SEN-
SOR FAULT”.
In case of fault signals, stop the
car, shut the engine off, then try to
clean the sensors, making sure that
you are not close to ultrasound-
emitting sources (e.g. truck air
brakes or pneumatic hammers). If
the cause of the operation anomaly
has been remedied, the system fully
resumes its functions and the fault
symbol on the multifunction display
goes out, together with its respective
warning message. Rear sensors are auto-
matically switched off
when the trailer’s electric
cable plug is inserted into the car
tow hitch socket.TOWING A TRAILER

CONTAINING RUNNING COSTS AND
POLLUTION
Some suggestions which may help
you to keep the running costs of the
car down and lower the amount of
toxic emissions released into the
atmosphere are given below.
GENERAL CONSIDERATIONS
Car maintenance
The overall state of the car is an
important factor which has a
marked influence over fuel con-
sumption and driving comfort and
on the life span of your car. For this
reason care should be taken to main-
tain your car by carrying out the
necessary checks and regulations in
accordance with the specifications
given in the “Service Schedule” (see
sections: spark plugs, air cleaners,
timing...).Tyres
Tyre pressure should be checked at
least once every four weeks: if the
pressure is too low fuel consumption
increases as the resistance to the
rolling movement of the tyre is
greater. In this state, tyre wear is
increased and handling suffers,
which will effect safety.
Unnecessary loads
Do not travel with too much load in
the boot. The weight of the car (in
town traffic above all), and its trim
greatly effect consumption and sta-
bility.Roof rack/ski rack
Remove the roof or ski racks from
the car as soon as they are no longer
needed. These accessories reduce the
aerodynamic penetration of the car
and will increase consumption.
When transporting particularly
large objects, use a trailer, where
possible.
Electrical devices
Use electrical devices for the neces-
sary time only. The heated rear win-
dow, fog lights, windscreen wipers,
heater fan require large amounts of
electricity and increasing the request
for power will also increase fuel con-
sumption (up to +25% when driving
in towns).
Climate control system
The climate control system is an
additional load which greatly effects
the engine leading to higher con-
sumption (up to +20% in average).
When the temperature outside
allows, use the air vents where pos-
sible.

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.

Do not smoke while
working in the engine
compartment: the pres-
ence of flammable gas and
vapour could cause a fire.
Be careful not to mix up
the various types of fluids
when you are topping up:
they are all mutually incompati-
ble and could damage the car.
Maintenance of your car
should be entrusted to a
Lancia Dealership. For
ordinary routine maintenance
operations which you are able to
carry out yourself, ensure that
you have the necessary tools and
original Lancia spare parts and
fluids available. Do not carry out
servicing operations if you have
no experience.IMPORTANT - Engine oil
If the car is normally driven in one
of the following particularly severe
conditions:
– towing a trailer
– on dirty roads
– for short, repeated trips (less
than 7-8 km) with outside tempera-
ture below zero
– with engine frequently idling or
for long distances at low speed (e.g.
taxi, door-to-door deliveries) or pro-
longed storage
change the engine oil more frequent-
ly than shown in the Service
Schedule.
IMPORTANT - Air cleaner
Replace the air cleaner more fre-
quently than shown in the Service
Schedule if the car is used on dusty
roads.
If you are in doubt about how often
the engine oil or the air cleaner
should be changed in relation to how
you use the car, contact a Lancia
Dealership.
