Traffic and road conditions
Heavy traffic and higher consump-
tion are synonymous, for example
when driving slowly with frequent
use of lower gears or in towns where
there are numerous traffic lights.
Winding roads, mountain roads
and bumpy roads also have a nega-
tive effect on consumption.
Enforced halts
During prolonged stops (level
crossings, etc.) the engine should be
switched off.Environmental protection has been
one of the guiding principles in the
production of the THESIS.
It is not accident that its pollution
control equipment is much more
effective than that required by cur-
rent legislation.
Nonetheless, the environment can-
not get by without a concerted effort
from everyone.
By following a few simple rules you
can avoid harming the environment
and often cut down fuel consump-
tion at the same time. On this sub-
ject, a few useful tips have been
given below to supplement those
marked by symbol #, at various
points of the handbook.
You are asked to read both the for-
mer and the latter carefully.CHEAP RUNNING THAT RESPECTS THE
ENVIRONMENT
LOOKING AFTER EMISSION
CONTROL DEVICES
The correct use of pollution control
devices not only ensures respect for
the environment but also has an
effect on the car’s performance.
Keeping these devices in good condi-
tion is therefore a fundamental rule
for driving that is easy on your
pocket and on the environment too.
The first step is to follow the
“Service Schedule” to the letter.
Only use unleaded petrol for petrol
engines (95 RON), for JTD versions
only diesel fuel (EN590 specifica-
tion).

263
Ignoring the above rules
may lead to fire. When functioning nor-
mally, the catalytic con-
verter reaches high tem-
peratures. For this reason, do not
park the car over inflammable
material (grass, dry leaves, pine
needles, etc.): fire hazard.
Do not allow anything to
be sprayed onto the cat-
alytic converter, lambda
sensor and exhaust pipe. Do not install other heat
shields and do not remove
those already fitted to the
catalytic converter and exhaust
pipe. Never run the engine with the
spark plugs disconnected even for
testing purposes. Do not warm up
the engine by letting it idle for a
while before moving off unless the
outside temperature is very low and,
even in this case, only do so for less
than 30 seconds.
If you have trouble starting, do not
keep turning the ignition key for
long periods. Be especially careful to
avoid bump starting the car by
pushing, towing or rolling downhill:
these are all manoeuvres that can
damage the catalytic exhaust sys-
tem. Use an auxiliary battery for
start-ups only.
If the engine begins to “lose its
smoothness” when travelling, con-
tinue your journey but reduce the
demands you are making on the
engine and have the car seen at a
Lancia Dealershipas soon as you
can.
When the instrument panel fuel
reserve warning light comes on, fill
up as soon as possible. A low level of
fuel can cause an uneven supply of
fuel to the engine with the inevitable
increase in the temperature of the
exhaust gas and serious damages to
the catalytic converter.

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.

269
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.

270
– 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
ACCESSORIES
In addition to the legal require-
ments we recommend keeping the
following in the car (fig. 2):

base disinfectant, sterile gauze, a roll
of gauze bandage, plasters, etc.,
– torch,
– round-nosed scissors,
– work gloves,
- fire extinguisher.

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.
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
braid Dof the car to be started.

7) Start the engine.
8) When the engine has started,
remove the leads in the reverse order
to before: D, C, Band finally A.
IMPORTANT If the engine fails to
start after a few attempts, do not keep
turning the key but have the car seen
to at a Lancia 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.

CHANGING
A WHEEL
Please note:
– the jack weighs 2.100 kg;
– the jack requires no adjustments;
– the jack cannot be repaired. If it
breaks, it must be replaced with a
genuine spare part;
– no other tool, part from the
ratchet wrench, can be fitted to the
jack.Change the wheel as follows:
1) Stop the car so that it is not a
hazard for other road users or your-
self when changing the wheel. The
ground should be as flat and firm as
possible.
2) Turn engine off and engage the
electric parking brake.
3) Engage first gear or reverse. On
versions with automatic gearbox
shift the lever to P.4) Open the boot.
5) Fold the boot carpet A(fig. 4).
6) Take out the warning triangle A
(fig. 5) and the tool kit B.
7) Release the locking device A
(fig. 6) and take out the jack holder
Band the spare wheel C, then place
them next to the wheel to be
changed.

FRONT FOG LIGHTS (where
provided) (fig. 24)
To replace front fog lights it is nec-
essary to operate under the vehicle,
after removing the protective cover
under the engine. For this reason, it
is suggested to have the bulbs
replaced at a Lancia Dealership.
