DEVICES FOR REDUCING PETROL ENGINE EMISSIONS
Three-way catalytic converter (catalytic exhaust pipe)
The exhaust system is equipped with a catalyst made up of noble metal alloys; it is housed in a
stainless steel container capable of withstanding the very high operating temperatures.
The catalyst converts the unburnt hydrocarbons, the carbon monoxide and the nitric oxides found
in the exhaust gases (though in small amounts, thanks to the electronic-injection ignition systems)
into non-polluting substances.
When functioning normally, the catalytic converter reaches high temperatures. For this reason do
not park the car over inflammable material (e.g. paper, fuel oil, grass, dead leaves, etc.).
Lambda sensors
The Lambda sensors detect the oxygen content in the exhaust gas. The signal sent by the oxygen
sensor is used by the injection system electronic control unit to constantly mix air and fuel in the cor-
rect proportion.
Fuel evaporation canister
As it is impossible to stop the build up of petrol fumes, also when the engine is not running, the sys-
tem traps them in a special container holding active carbon.
The fumes are sucked in from here and burnt while the engine is running.

Diesel engines
Use diesel fuel only.

locking controls, press the driver's
door button A(fig. 37) for more than
one second. When controls are off, the
button warning light will come on.
To restore controls, press button A
again. When controls are enabled, the
button warning light is off.CHILD LOCK

Always use the lock when
transporting children. This
will prevent them opening
a door by themselves when travel-
ling.

FUNCTIONS THAT CAN BE
MODIFIED BY THE CONNECT
MENU
The CONNECT enables to switch
on/off the following functions:
– locking/unlocking the boot
together with central door
locking/opening– automatic locking of the boot,
door locks and fuel filler cap, when
the car speed exceeds 20 km/h.
To actuate these settings, refer to
the CONNECT supplement provid-
ed with the car.The following tables summarize
the operation logic of the boot lock,
depending on the functions that
have been actuated.

If repairs need to be car-
ried out inside the engine
compartment when this is
still hot, be careful not to burn
yourself and keep away from the
electric fan as this may cut in at
any time, even if the key is
removed from the ignition switch.
Wait until the engine has cooled.
Scarves, ties and other
loose articles of clothing
could easily get caught up
in moving parts.To close the bonnet:
Lower the bonnet at approx. 20 cm
from the engine compartment and
then let it drop, ensuring that it is
fully closed and not just held in posi-
tion by the safety catch. If the bonnet
does not close properly do not push it
down but open it again and repeat the
above procedure.
For safety reasons the
bonnet shall always be
perfectly closed when trav-
elling. Always check for proper
bonnet locking. If the bonnet is left
inadvertently open, stop the car
immediately and close the bonnet.FUEL FILLER CAP
The fuel filler cap flap is controlled
automatically controlled by the cen-
tral door locking system.
When central door locking is on,
the fuel filler flap cannot be opened;
when central door locking is off, the
flap can be opened by simply press-
ing on the front part in point A(fig.
215).
Open the fuel filler flap by turning
it in the direction shown by the
arrow until it is completely opened.

239
In an emergency, the flap can be
released by pulling wire B(fig. 216)
on the right-hand side of the boot
inside the service compartment.
To open the compartment flap,
turn the catch C(fig. 217) to 1using
the ignition key and lower it.IMPORTANT The airtight seal of
the cap may lead to a slight increase
of pressure in the tank. A hissing
sound when the cap is removed is
therefore quite normal.
The cap is equipped with a device
which fastens it to the flap so that it
cannot be misplaced D(fig. 218).
While you are filling up, fasten the
cap to the device inside the flap as
shown in the figure.
Do not put naked flames
or lighted cigarettes near
the fuel filler hole as there
is a danger of fire. Do not bend too
close to the hole either so as not to
breathe in harmful vapours.REFUELLING
To guarantee full tank filling, carry
out two refuelling operations after the
first click of the fuel delivery gun. Avoid
further topping up operations that
could cause damages to the fuel system.
IMPORTANTRefuelling shall always
be performed with engine off and igni-
tion key to STOP. If the engine is off
but the key is to MAR, a wrong fuel
level could temporarily be indicated.
This is due to the internal system con-
trol logic and cannot be considered as
a system malfunctioning.

ADDITIONAL
CHECKS
Every 1,000 kmor before long
trips, check and top up as necessary:
– engine coolant level
– brake/hydraulic clutchfluid
level
– power steering fluid level
– windscreen/rear window and
headlight washer fluid level
– tyre pressure and conditions.
Every 3,000 kmcheck the engine
oil level and top up as necessary.
You are recommended to use FL
Seleniaproducts that are designed
and produced specifically for LAN-
CIA cars (see “Capacities” in
“Technical Specifications”).
ANNUAL
INSPECTION
SCHEDULE
The following annual inspection
schedule is recommended for
cars travelling less than 20,000
km a year (e.g. approximately
10,000 km). The schedule
includes the following opera-
tions:
1) Check tyre condition and wear
and adjust pressure (including spare
wheel)
2) Check wear on windscreen/rear
window blades
3) Check rear disc brake pad con-
ditions and wear
4) Inspect conditions of: under-
body protection and outside body-
work, piping (exhaust - fuel lines -
brake lines), rubber parts (boots -
sleeves - bushings, etc.), brake and
fuel line hoses5) check for bonnet and boot lock
cleanness, lever cleanness and lubri-
cation
6) Check primary and secondary
battery charge status
7) Check conditions of various con-
trol belts
8) Check and top up fluid levels
(engine coolant, brakes, windscreen
washer, battery, etc.)
9) Change engine oil
10) Replace engine oil filter
11) Replace dust/pollen filter.

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.
