RUBBER
TUBING

Follow the Service Schedule to the

letter as concerns braking, power
steering and fuel line rubber tubing.
Ozone, high temperatures and long
absence of fluid in the system can in
fact cause the hardening and crack-
ing of the pipes with possible loss of
fluid. A careful check is therefore
essential.

WINDSCREEN
WIPERS

BLADES

Periodically clean the rubber part

with suitable products. We recom-
mend TUTELA PROFESSIONAL
SC 35.

Change the blades if the rubber

edge is warped or worn out. You
should in any case change them
approximately once a year.

Some simple steps can reduce

potential damage to the blades:

– If the temperatures falls to below

zero, make sure the rubber blade is
not frozen to the windscreen. If nec-
essary, free it with a de-icing com-
pound.

– Remove any snow that has settled

on the glass: besides saving the
blades you will avoid straining the
electric windscreen wiper motor and
causing it to overheat.

– Do not operate the windscreen

wipers on dry glass.

Travelling with worn

wiper blades is dangerous
because it reduces visibil-

ity in bad weather.

Checking the blades

Before checking, clean the wind-

screen and rubber blades carefully
with warm water and soap or with
TUTELA PROFESSIONAL SC 35
windscreen washing fluid. The
windscreen should be perfectly clean
and not greasy. If required, complete
the cleaning operation with degreas-
ing products (ammonia based) or
degreasing polishes.

334

SPRAY NOZZLES (fig. 21)

If there is no jet of liquid, first

make sure that there is liquid in the
reservoir. Then make sure that the
holes in the nozzles are not clogged
up. Use a pin for this if necessary.

The windscreen washer jets can be

directed through screw A. Direct the
spray so that it reaches the highest
point reached by the blades.

fig. 21

L0A0163b

The blades must also be perfectly

clean before starting the check. If
required, clean the corners with
warm water and soap.

1) Check the blades carefully. They

should not be broken or damaged in
any part. Replace both the blades if
they are broken or damaged.

2) If the blades are intact, continue

by checking the operation. Operate
the windscreen washer and the
wiper. If the blades clean the wind-
screen perfectly they can be kept. If
not, replace them both.

Replacing the blades 
(fig. 20)

To replace the windscreen wiper

blades:

1) Lift the windscreen wiper arm.

2) Press the lock spring tab and

remove the blade A from arm B.

3) Insert the new blade in the

windscreen wiper arm until the lock
spring clicks.

IMPORTANT

After replacing,

make sure that the blades are cor-
rectly fastened to the windscreen
wiper arm.

HEADLIGHT
WASHERS

Regularly check that the nozzles

(fig. 22) are intact and clean.

The headlight washers are auto-

matically switched on when the
windscreen washer is operated and
the headlights are on.

CLIMATE 
CONTROL SYSTEM

During the winter, the climate con-

trol system must be turned on at
least once a month for about ten
minutes.

Before summer, have the system

checked at a Lancia Dealership.

INITIALISING THE AIR
CONDITIONING CONTROL UNIT 

Whenever the battery is electrically

connected again or it is reloaded after
being completely flat or after replac-
ing one of the protection fuses, to re-
store the correct operation of the air
conditioning, of the door locking and
of the ESP system. It is necessary to
perform the initialisation operations
contained in the paragraph “If battery
is to be disconnected” in the chapter
“In an emergency”. 

fig. 22

L0A0122b

The system is filled with

R134a refrigerant which
will not pollute the envi-

ronment in the event of leakage.
Under no circumstances should
R12 fluid be used as it is incom-
patible with the system compo-
nents and contains CFC.

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.

337

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.

TIPS FOR KEEPING THE BODY
IN GOOD CONDITIONS

Paintwork

The paintwork is not only to make

your car look attractive but also to
protect the steel.

If the paint is scuffed or scratched

deeply you are therefore advised to
touch up as necessary to prevent rust
from forming.

Only use genuine products when

touching up the paintwork (see
“Bodywork paint identification
plate” in chapter “Technical
Specifications”).

Ordinary maintenance of the

paintwork means washing it. The
frequency you should do this
depends on the conditions and the
environment the car is driven in. For
example, you should wash your car
more often if it is driven in areas
with a high level of air pollution or
on road sprinkled with saltwash.

Before leaving your car

into the automatic car-
wash tunnel, disengage

the parking brake following the
instructions given in the relevant
paragraph, and leave the Keyless
System CID (where fitted) in the
car to prevent automatic steering
locking.

Before cleaning the

windscreen (e.g. at filling
stations), make sure to

have deactivated the rain sensor
and turned the ignition key to
STOP. Deactivate the rain sensor
also when washing your car man-
ually or at automatic carwash.

338

Outside plastic parts must be

cleaned following the usual car
washing procedure. 

Where possible avoid parking the

car under trees; the resinous sub-
stance that certain species of tree
shed dull the paintwork and increase
the possibility of rust forming.

IMPORTANT

Bird droppings

must be washed off immediately and
with great care as their acid is par-
ticularly aggressive.

Windows

Use specific window cleaners to

clean the windows. Use very clean
cloths to avoid scratching the glass
or damaging the transparency.

IMPORTANT To prevent damage

to the electric heater element, wipe
the inside of the heated rear window
gently in the same direction as the
elements.

To wash the car properly:

1) Remove the aerial from the roof

to prevent damaging it when wash-
ing the car in an automatic carwash.

2) Wash the body using a low pres-

sure jet of water.

3) Wipe a sponge with a light neu-

tral PH detergent solution over the
bodywork, frequently rinsing the
sponge.

4) Rinse well with water and dry

with a jet of air or a chamois leather.

When drying the car, be careful to

get at those parts which are not so
easily seen e.g. the door frames, bon-
net and around the headlights where
water can most readily collect.

You should leave the car out in the

open so that any water remaining
can evaporate more easily.

Do not wash the car after it has

been parked in the sun or while the
bonnet is hot: it could take the shine
off the paint.

Cleaning chromium
plated/anodized bodywork parts

To clean body parts such as mold-

ings, cappings, etc., use neutral pH
detergents. Avoid generic cleaning
products.

These parts shall be rinsed well with

water and then dried with a jet of air
or a chamois leather. 

For further treatment use special

polish for chromium plated/anodized
parts.

Suitable car cleaning products are

available at Lancia Dealerships.

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.

IMPORTANT The 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.

IMPORTANT Do 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.

340

CLEANING VELVET SEATS
AND FABRICS

– Remove dust with a soft brush

and vacuum cleaner. Use a moist
brush to clean velvet upholstery.

– Brush the seats with a damp

sponge with water and a neutral
soap.

CLEANING LEATHER SEATS

– Remove the dry dirt with a

chamois leather or very slightly
moist loth without exerting too
much pressure.

– Remove liquid or grease stains

with a dry absorbent cloth without
rubbing. Then wipe with a chamois
leather or soft cloth moistened with
water and neutral soap. If the stain
does not come out, use a special
cleaning compound being particu-
larly careful to follow the instruc-
tions for use.

IMPORTANT Never use alcohol or

alcohol-based products.

STEERING WHEEL/GEAR
LEVER KNOB WITH GENUINE
LEATHER COVERING

These components shall only be

cleaned with water and neutral soap.
Never use spirit or alcohol-based
products.

Before using special products for

cleaning interiors, read carefully label
instructions and indications to make
sure they are free from spirit and/or
alcohol-based substances. 

If when cleaning the windscreen

with special glass products, some
drops fall on the leather covering of
the steering wheel/gear lever knob re-
move them immediately and then
clean with water and neutral soap.

IMPORTANT Take the utmost care

when engaging the steering lock to
prevent scratching the leather cover-
ing.

Upholstery of your car

has been designed to with-
stand wear deriving from

common use of the car. You are
however recommended to avoid
strong and/or continuous scratch-
ing with clothing accessories such
as metallic buckles, studs, Velcro
fastenings and the like, since these
items cause circumscribed stress
of the cover fabric that could lead
to yarn breaking, and damage the
cover as a consequence.
