The engine cooling sys-
tem works with PARAFLU
UP. Top up only with the
same fluid contained in the cool-
ing circuit. PARAFLU UP cannot
be mixed up with PARAFLU 11 or
other fluids. Should this take
place, do not start the engine and
contact a Lancia Dealership. In
case of need, lacking the speci-
fied fluid, top up with water and
contact a Lancia Dealership to
have the proper proportions
restored.
The cooling system is
pressurised. If necessary,
replace the cap with a
genuine spare part to avoid com-
promising the system efficiency.
The mixture of distilled water
and PARAFLU gives freeze pro-
tection down to -35°C. POWER STEERING FLUID
(fig. 14-15)
Fluid level in the reservoir should
be at the maximum.
This check should be performed
when the engine is cold and with the
car on level ground.
For topping up, remove cap A,
after loosening the fastening screws
Bwith the wrench provided (in the
tool bag), then remove hose Cand
loosen cap D.
Check that the level reaches the
MAXreference line on the dipstick
integral with the reservoir cap (for
cold check use the level indicated on
the 20 °C side of the dipstick).If the fluid level in the reservoir is
below the specified one, top up only
with one of the products shown in
table “Fluids and lubricants” in
chapter “Technical Specifications”
proceeding as follows:
– Start the engine and wait for the
oil level in the reservoir to stabilise.
– With the engine running, turn the
steering wheel lock to lock a few
minutes.
– Top up to the MAXreference line
and then refit the cap D.

323
Oil consumption is ex-
tremely low. If the oil level
needs topping up again af-
ter a short period of time, have the
system checked for leakage at a
Lancia Dealership.BRAKE AND HYDRAULIC
CLUTCH FLUID (fig. 16)
Unscrew cap A: check that the fluid
level in the reservoir is at maximum.
Fluid level in the reservoir shall not
exceed the MAXmark.
If fluid has to be added, it is sug-
gested to use the brake fluid in table
"Fluids and lubricants" (see chapter
"Technical characteristics").
NOTEClean accurately the tank cap
Aand the surrounding surface.
Prevent brake fluid, which
is highly corrosive, from
coming into contact with
painted parts. Should it happen,
immediately wash with water.
Do not let the power
steering fluid come into
contact with hot engine
parts. It catches fire very easily.

– Refit hose C.
– Refit cap Aand check for seal
proper positioning into its seat, then
secure the cap with screws B.At plug opening, pay maximum at-
tention in order to prevent any impu-
rities from entering the tank.
For topping up, always use a funnel
with integrated filter with mesh equal
to or lower than 0.12 mm.
IMPORTANT Brake fluid absorbs
moisture, for this reason, if the car is
mainly used in areas with a high de-
gree of atmospheric humidity, the
fluid should be replaced at more fre-
quent intervals than specified in the
“Service schedule”.

WINDSCREEN/REAR
WINDOW/HEADLIGHT
WASHER FLUID (fig. 17)
To top up, remove cap Aand filler
B.
Pour in a mixture of water and
TUTELA PROFESSIONAL SC 35
fluid in the following concentrations:
– 30% of the above specified fluid
and 70% water in summer
– 50% of the above specified fluid
and 50% water in winter
– if the temperature falls below –20
°C use TUTELA PROFESSIONAL
SC 35undiluted.Certain commercial
additives for windscreen
washers are inflammable.
The engine compartment con-
tains hot components which may
set it on fire.
Do not travel with the
windscreen washer reser-
voir empty. The wind-
screen washer is fundamental for
improving visibility.
fig. 17
L0A0295b
To prevent damages to
the pump motor, do not
use the windscreen/rear
window/headlight washers when
the reservoir is empty.
The symbol πon the
container indicates syn-
thetic brake fluid, distin-
guishing it from the mineral kind.
Using mineral fluids irreversibly
damages the special braking sys-
tem rubber seals.
Brake fluid is poisonous
and highly corrosive. In
the event of accidental
contact, wash the parts involved
immediately with neutral soap and
water, then rinse thoroughly. Call
the doctor immediately if the fluid
is swallowed.

325
AIR CLEANER
The air cleaner is connected to the
air temperature and intake sensors
which send the electrical signals
required for the correct operation of
the injection and ignition system to
the control unit.
Consequently, the cleaner must
always be in perfect conditions to
ensure correct operation of the
engine and in order to contain con-
sumption and exhaust emissions.Replace the air cleaner
more frequently than
shown in the Service
Schedule if the car is used on
dusty roads.
The cleaner can be dam-
aged if it is cleaned and
consequently the engine
can be damaged.
DIESEL FILTER
(JTD versions)
DRAINING THE
CONDENSE
The presence of water in
the fuel feed circuit can
severely damage the
injection system and make the
engine misfire. Go to a Lancia
Dealership as soon as possible
when the cwarning light comes
on together with message
“WATER IN DIESEL FILTER” on
the multifunction display to have
the bleeding operation carried
out.
The air cleaner replace-
ment procedure is pro-
vided for indicative pur-
poses only. Have the operation
carried out at a Lancia
Dealership. Car safety can be
compromised if the cleaner
replacement procedure herein
described is not carried out cor-
rectly.

329
USEFUL ADVICE FOR
LENGTHENING THE LIFE OF
YOUR BATTERY
To prevent rapidly draining the
battery and ensure that it continues
to work correctly, the following
should be noted:
– Terminals must always be firmly
tightened.
– Do not keep accessories (e.g.
sound system, hazard lights, parking
lights, etc.).
– When you park the car, ensure
the doors, boot and bonnet are
closed properly. The ceiling lights
must be off.
– Before working on the electrical
system, disconnect the negative
cable from the battery.– If after buying the car, you want
to install electric accessories which
require permanent electric supply,
visit a Lancia Dealership, whose
qualified personnel, in addition to
suggesting the most suitable devices
belonging to the Lineaccessori
Lancia, will evaluate the overall
electric absorption, checking
whether the car’s electric system is
capable of withstanding the load
required, or whether it should be
integrated with a more powerful
battery. These devices in fact take
electricity also when the ignition key
is removed (car parked, engine off),
and can gradually drain the battery.
The overall intake of these devices
(standard and after-market) must
be less than 0.6 mA x Ah (of the bat-
tery), as shown in the following
table.Battery Maximum
idle intake
70 Ah 42 mA
80 Ah 48 mA
100 Ah 60 mA
It is also important to remember
that high intake devices (such as
bottle warmers, vacuum cleaners,
cellular phones, frigo bar, etc.) will
speed up battery discharging when
powered with engine off or running
idle.
– Please note that when installing
additional systems in the car, incor-
rect wiring can be dangerous espe-
cially when concerning safety sys-
tems.

330
SPARK PLUGS
The cleanness and soundness of the
spark plugs are very important for
keeping the engine efficient and pol-
luting emissions down.
The appearance of the spark plug,
if examined by expert eyes, is a good
way of pinpointing a problem even if
it has nothing to do with the ignition
system. Therefore, if the engine has
problems, it is important to have the
spark plugs checked at a Lancia
Dealership.
The spark plugs must be
changed at the times
specified in the Service
Schedule. Only use the type of
plugs indicated. If the heat ratio
is less than required or the life
specified is not guaranteed, prob-
lems can arise.
ELECTRONIC
CONTROL UNITS
When the car is being used normal-
ly, special measures are not neces-
sary.
The following instructions must be
followed very carefully, however, if
you work on the electrical system or
in cases where emergency starting is
necessary:
– never disconnect the battery from
the electrical system while the
engine is running
– disconnect the battery from the
electrical system if you are recharg-
ing it. The modern battery chargers
can discharge voltage up to 20V
– never perform emergency start-
ups with a battery charger. Always
use an auxiliary battery
– be particularly careful when con-
necting the battery to the electrical
system. Make sure that the polarity
is correct and that the connection is
efficient– do not connect or disconnect the
terminals of the electronic control
unit while the ignition key is at MAR
– do not check polarity through
sparking
– disconnect the electronic control
units if you are electrically welding
the car body. Remove the units if
temperatures exceed 80°C (special
operations on the bodywork, etc.).
Modifications or repairs
to the electrical system
carried out incorrectly
and without bearing the features
of the system in mind can cause
malfunctions with the risk of fire.

BODYWORK
PROTECTING THE CAR FROM
ATMOSPHERIC AGENTS
The main causes of rust are:
– atmospheric pollution
– salty and humidity in the atmos-
phere (coastal or very hot and
humid areas)
– environmental conditions that
specific to the season.
In addition, the abrasiveness of
dust in the atmosphere and sand
carried by the wind as well as mud
and stones kicked up by other cars
must not be underestimated.
For your THESIS, LANCIA has
used leading-edge technological
solutions to effectively protect the
body from rust.These are most important:
– Painting systems and products
that make the car particularly resis-
tant to rust and scratching.
– The use of zinc-plated sheet steel
which is highly resistant to rust.
– The spraying of the underbody,
engine compartment, inside the
wheelhouses and other parts with
wax-based products with a high pro-
tective capacity.
– Spraying plastic-coating materi-
als, to protect the most exposed
points: under the door, inside the
wings, the edges, etc.– The use of “open” box sections to
prevent condensation and water
from building up and rusting the
inside of the parts.
BODY AND UNDERBODY
WARRANTY
Your THESIS is covered by war-
ranty against any original structural
or body part being perforated by
rust. Refer to the Warranty Booklet
for the general terms.

339
Engine compartment
At the end of each winter season,
carefully clean the engine compart-
ment without directing the water jet
against electronic control units.
Have this done at a garage.
Detergents pollute water.
For this reason the car
must be washed in an
area equipped for the collection
and purification of the liquids
used while washing.
IMPORTANTThe car should
washed with the engine cold and the
ignition key at STOP. After washing
make sure that the various protec-
tions (e.g. rubber caps and various
covers) have not been damaged or
removed.INTERIORS
From time to time check that water
has not collected under the mats
(from dripping shoes, umbrellas,
etc.) which could cause the steel to
rust.
Never use inflammable
products like fuel oil
ether or rectified petrol
for cleaning inside the car. The
electrostatic discharges generat-
ed when rubbing to clean may
cause fire.
Do not keep aerosol cans
in the car. There is the
risk they might explode.
Aerosol cans must never be
exposed to a temperature above
50°C; when the weather starts to
get hot the temperature inside the
car might go well beyond that fig-
ure.
PLASTIC PARTS INSIDE
THE CAR
Use special products designed not
to alter the appearance of the com-
ponents.
IMPORTANTDo not use alcohol
or petrol to clean the instrument
panel.
CLEANING ALCANTARA
SEATS
Alcantara upholstery is easy to
clean. Follow the same instructions
provided for velvet upholstery.
