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 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”.

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.

326
Batteries contain sub-
stances that are very
harmful for the environ-
ment. You are advised to have the
battery changed at a Lancia
Dealership. It is properly
equipped for disposing of used
batteries in an environmentally-
friendly way that complies with
the law.
With the battery flat, or
after the interruption of
one of the protection
fuses, or if you want to disconnect
a loaded battery (e.g. for a car
stop period), before opening the
luggage compartment bonnet
carefully read and comply with
the instructions contained in the
paragraph “If battery is to be dis-
connected” in the chapter “In an
emergency”.
DUST/POLLEN
FILTER
This filter has a mechanical/elec-
trostatic air filtering action, provid-
ed that windows and doors are
closed.
Have the dust/pollen filter checked
once a year at a Lancia Dealership,
preferably at the onset of summer.
If the car is often used in dusty or
extremely polluted environments,
have the filter replaced more fre-
quently than specified in the Service
Schedule.
IMPORTANTFailure to replace
this filter can significantly reduce
climate control system effectiveness.
BATTERY
The battery is of the “Low
Maintenance” type and is fitted with
an indicator A(fig. 18) for checking
the electrolyte level and battery
charge.
Under normal condition of use top-
ping up the electrolyte with distilled
water is therefore not required. A
periodical check is however neces-
sary to make sure it is in efficient
conditions through the indicator on
the battery cover which should be
dark in colour with a green central
area.If the indicator is a bright colour,
or dark without the green central
area, contact a Lancia Dealership.

328
CHARGING THE BATTERY
IMPORTANTThe battery charg-
ing procedure is described only for
information purposes since this
operation must be carried out by a
Lancia Dealership.
Charging should be slow at a low
amp rating for about 24 hours.
Charging for a longer period of time
may damage the battery.
Before reloading care-
fully read and comply with
instructions contained in
the paragraph “If battery is to be
disconnected” in the chapter “In
an emergency”.
To charge the battery proceed as
follows:
– Disconnect battery negative ter-
minal (–).
– Connect the battery charger wires
to the battery terminals and check
for proper bias.
– Turn the battery charger on.– After charging, turn the battery
charger off before disconnecting it
from the battery.
– Reconnect the battery negative
terminal (–).
The liquid in the battery
is poisonous and corrosive.
Do not let it touch the skin
or eyes. Recharging the battery
should be done in a well-venti-
lated area and away from naked
flames or possible sources of
sparks: explosion and fire risk.
Never attempt to charge
a frozen battery: it must
be thawed first, otherwise
it may explode. If freezing has
took place, the battery should be
checked before charging by spe-
cialised personnel, to make sure
that the internal elements are not
damaged and that the body is not
cracked, with the risk of leaking
poisonous and corrosive acid.IMPORTANTA battery which is
kept at a charge of less than 50% for
any length of time will be damaged
by sulphation leading to a reduction
in cranking power and a higher risk
of the battery electrolyte freezing
(this may even occur at –10 °C). If
the car is inactive for a long period
of time, refer to “Storing the car”, in
chapter “Driving your car”.
REPLACING THE
BATTERY
If required, replace the battery
with a genuine spare part presenting
the same specifications. If a battery
with different specifications is fitted,
the frequencies shown in the Service
Schedule in this chapter will no
longer apply. Refer to the instruc-
tions provided by the battery
Manufacturer.
IMPORTANTBefore 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”.

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.

333
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
