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
atSTOPor 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.

EMERGENCY
START-UP
If the Lancia CODE system cannot
deactivate the engine immobilising
system, symbols YandUwill
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 STOPand
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. TheUwarning 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 MARtoAVV
(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.
IN AN EMERGENCY

272
JUMP STARTING
If the battery is flat, you can use
another battery to start the engine.
Its capacity must be the same or
slightly greater than the flat battery
(see the “Technical Specification”
chapter).
The battery is placed on the left
side of the boot, protected by a
cover.Before opening the lug-
gage compartment bonnet
to reload the battery or to
connect an auxiliary battery,
carefully read and comply with
the instructions contained in the
paragraph “If battery is to be dis-
connected” in the chapter “In an
emergency”.
Jump starting does not damage the
Lancia CODE system. Proceed as
follows:
1) Disconnect all electrical devices
that are not strictly useful.
2) Lift the boot tailgate by turning
the key metal insert clockwise in the
latch.3) Loosen the knob A(fig. 1) and
remove the protective cover B.
4) Press flanges A(fig. 2) and
remove the cover B.
5) Connect the positive terminals
(+)A(fig. 3) and Bof the two bat-
teries with a jump lead.
6) With a second lead connect first
the negative terminal (–)Cof the
auxiliary battery and then the earth
braidDof the car to be started.

273
7) Start the engine.
8) When the engine has started,
remove the leads in the reverse order
to before: D,C,Band finally A.
IMPORTANTIf the engine fails to
start after a few attempts, do not keep
turning the key but have the car seen
to at aLancia Dealership.
9) Put the cover back on the bat-
tery positive terminal by fitting the
lock flanges in.
10) Put the cover back and retight-
en the knob.
11) Close the boot tailgate.IMPORTANTWhen the tailgate is
closed, the boot latch is not locked.
To lock it, turn the metal insert of
the key anticlockwise in the latch.
Do not carry out this
procedure if you lack
experience: if it is not
done correctly it can cause very
intense electrical discharges and
the battery might even explode.
Do not to put naked flames or
lighted cigarettes near the battery
and do not cause sparks: risk of
explosion and fire.
Never use a battery
charger to jump start the
engine: you could damage
the electronic system, with spe-
cial reference to ignition and
injection control unit.
BUMP STARTING
Do not bump start by pushing,
towing or coasting downhill. This
way of starting could cause a rush of
fuel into the catalytic converter and
damage it beyond repair.
Remember that ifthe engine is not
running, the brake booster and the
power steering will not work. You
therefore have to use considerably
more effort on both the brake pedal
and the steering wheel.
Never connect the nega-
tive terminals of the two
batteries directly: sparks
could ignite the flammable gas
from the battery. If the auxiliary
battery is installed on another
car, prevent accidental contact
between the metal parts of the
two vehicles.

284
IF AN EXTERIOR
BULB BURNS OUT
FRONT LIGHT CLUSTER
The front light cluster includes
main beam headlights/dipped beam
headlights, additional main beam
headlights, direction indicators and
sidelights.Light layout is the following
(fig. 23):
A– Main beam headlight/dipped
beam headlight (bi-Xeno bulb)
B– Sidelight
C– Additional main beam head-
light
D– Direction indicator.Any operation on the
front light cluster must be
made with the stalk at 0
(lights off) and ignition key
removed for at least 15 minutes
(to let bulb cooling and con-
densers discharging): risk of elec-
trical discharge!
fig. 23
L0A0106b
To replace front head-
light bulbs, front light
clusters shall be removed.
It is therefore recommended to
the bulbs replaced at Lancia
Dealership.Due to high voltage, the
bulb of bi-Xeno gas-dis-
charge headlights must
only be replaced by experts: dan-
ger of death! Contact the Lancia
Dealership.

IF A FUSE BLOWS
GENERAL (fig. 67)
The fuse is a protective device for
the electric system. It comes into
action (i.e. it cuts off) in the event of
a failure or improper actions on the
electric system.
If an electrical device is not work-
ing, check whether the respective
fuse is blown. The conductor should
not be broken. If it is, replace it with
another with the same amperage
(same colour).A- Undamaged fuse
B- Fuse with broken filament.
Use the tongs Cto extract a fuse to
be replaced. The tongs are to be
found in the main fuse box.
Before changing a fuse,
check the ignition key has
been removed and that all
the other electrical devices have
been switched off.
fig. 67
L0A0127b
Never replace a fuse
with metal wires or any-
thing else. Always use an
intact fuse of the same colour
(same value).
Never change a fuse with
another of higher amper-
age: FIRE RISK!If a general fuse (MIDI-
FUSE or MEGA-FUSE)
blows, do not repair it,
but go to a Lancia Dealership.
If the fuse blows again,
have the car inspected at a
Lancia Dealership.

295
The devices protected by the fuses
(fig. 75) are listed in the tables on
the following pages.
After replacing the fuses refit the
cover by refitting the fastening clips.FUSES IN THE BOOT
The fusebox (fig. 77) is located on
the right side of the boot, inside the
service compartment.
To open the compartment flap turn
the catch A(fig. 76) to 1with the
ignition key and lower it. The spare fuses, with different
amperage, are housed in vertical
position at the sides of the fusebox.
