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.

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-
mendTUTELA 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.

FLUIDS AND LUBRICANTS
PRODUCTS WHICH MAY BE USED AND THEIR SPECIFICATIONS
Use
Lubricants for
petrol engines
Lubricants for
diesel engines
For regular operation of JTD versions fitted with DPF, use genuine lubricant only. In the event of an emergency, lacking the genuine
lubricant, top up just once with max. 0.5 l and go to Lancia Dealership as soon as possible
Should non-genuine products be used, lubricants with minimum ACEA A3 properties for petrol engines and ACEA B4 for Diesel en-
gines are tolerated; in this event top engine performance is not guaranteed.
Using low-quality products, not compliant with ACEA A3 and ACEA B4 properties and specifications could cause engine damages not
covered by warranty.
For very cold temperatures, consult Lancia Dealership for the proper Seleniaproduct to use.Original fluids and

PROVISIONS FOR THE PROCESSING OF A VEHICLE
AT THE END OF ITS LIFE-CYCLE
For years now Lancia has been developing its global commitment towards the safeguarding and protection of the
Environment through the continuous improvement of its production processes and the making of increasingly more
“eco friendly” products. With a view to guaranteeing the best possible service to clients in full observance of
environmental standards and in response to the obligations imposed by European Directive 2000/53/EC on end-
of-life vehicles, Lancia offers its clients the possibility to hand in their vehicle* at the end of its life span without
additional costs.
The European Directive, in fact, provides for the take-back of the vehicle without the last holder or owner of the
same incurring expenses due to the fact that the market value of the vehicle is zero or negative. In particular, in
almost all of the countries of the European Union, up until 1st January 2007, take-back of the vehicle free of
charge only applies to vehicles registered from 1 July 2002 on, while, from 2007 on, take-back will be carried out
free of charge, independently of the year of registration, provided that the vehicle still contains all its essential
component parts (especially engine and body) and is free from additional waste materials.
Our contracted network of authorised treatment facilities has been carefully selected in order to provide a quality
service to our customers by de-polluting and recycling “End of Life Vehicles” to approved environmental
standards. To find out the location of your nearest authorised treatment facility, offering free of charge take-back,
simply contact one of our dealers or refer to the Lancia web site or call the toll free number 00800 526242 00.
