IMPORTANTAfter topping up, let
the engine turn for a few seconds
and wait a few minutes after stop-
ping it before you check the level.
Engine oil consumption
Max. engine oil consumption is
usually 400 grams every 1000 km.
When the car is new, the engine
needs to run in, therefore the engine
oil consumption can only be consid-
ered stabilised after the first 5000 -
6000 km. ENGINE OIL
(fig. 7-8-9-10-11-12)
Check engine oil with the car on
level ground and while the engine is
still warm (approximately five min-
utes after stopping the engine).
Remove dipstick Aand clean it,
than plunge it down and check
whether the oil level is included
between the MINand MAXrefer-
ence lines on the dipstick. The gap
between the MINand MAXrefer-
ence lines corresponds to approxi-
mately one litre of oil.Do not add oil with dif-
ferent specifications (class,
viscosity, etc.) from the oil
already in the engine.
If the oil level is near or even below
the MINline, pour in oil through the
filler hole B, until it reaches the
MAXline.
IMPORTANTIf during a routine
check you will find that the oil level
is above the MAXreference line,
contact a Lancia Dealershipto
have the proper level restored. Be very careful under the
bonnet: you risk burning
yourself. Rememberthat
when the engine is hot, the fan
can start up and cause injuries.

IMPORTANTThe oil consump-
tion depends on the driving style and
the conditions under which the car is
used.Used engine oil and re-
placed oil filters contain
substances which can harm
the environment. We recommend
you have the car seen to at a Lan-
cia Dealership for the oil and filter
change. It is suitably equipped for
disposing of used oil and filters in
an environmentally friendly way
that complies with the law.ENGINE COOLANT (fig. 13)
Do not remove the reser-
voir cap when the engine is
hot: you risk scalding
yourself!
Check coolant level when the engine
is cold and with the car on flat
ground. The level should be includ-
ed between MINand MAXreference
lines on the reservoir.
If the level is low, loosen the reser-
voir cap Aand top up with
PARAFLU UPuntil reaching the
MAXreference line.

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.

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.

327
If the car is left inactive
for long periods at cold,
remove the battery and
store it in a warm place to pre-
vent freezing.CHECKING THE BATTERY
CHARGE
The quality of the battery charge can be checked through the indicator (where
required).
If the battery is not fitted with electrolyte level indicator, the relevant checks
must only be carried out by authorised personnel.
To check the battery charge, slacken the two fastening screws and open the
cover. Check the battery charge and then reclose the cover, take care to prevent
pinching and short circuits.
Depending on the colour of the indicator, proceed as described in the table
below or on the label B(fig. 18) on the battery. Incorrect fitting of elec-
trical and electronic
accessories can seriously
damage the car. If you want to
add accessories after buying the
car (free-hand phone kit, etc.)
visit a Lancia Dealership. They
can suggest the most suitable
accessories to get and check
whether the electric system can
support the required load or
whether a larger capacity battery
is required.
When working on the
battery or near it, always
wear the proper goggles.
Running the battery with
low fluid level can dam-
age the battery beyond
repair and could also cause its
explosion.
