MUST BE READ!
REFUELLING
Petrol engines:only refuel with unleaded petrol with octane rating (RON) no less than 95.
Diesel engines:only refuel with diesel fuel conforming to the European specification EN590.
The use of other products or mixtures may irreparably damage the engine with invalidation of the warranty
due to the damage caused.
ENGINE START-UP
Petrol engines with manual gearbox:make sure the parking brake is pulled (instrument panel warning light x
on); put the gear lever to neutral; press the clutch pedal down to the floor without touching the accelerator, then turn
the ignition key or the Keyless System knob to AVVand release it as soon as the engine starts.
Engines with automatic electronic transmission (COMFORTRONIC): make sure the parking brake is pulled (in-
strument panel warning light xon) and the gear lever is to P; hold the clutch pedal pressed down to the floor
without touching the accelerator, then turn the ignition key or the Keyless System knob to AVVand release it as soon
as the engine starts.
Diesel engines:make sure the parking brake is pulled; put the gear lever to neutral; press the clutch pedal down
to the floor without touching the accelerator, then turn the ignition key or the Keyless System knob to MAR, and
wait for the instrument panel warning light mto go out, then turn immediately the ignition key or the Keyless
System knob to AVVand release it as soon as the engine starts.
PARKING OVER FLAMMABLE MATERIAL
When functioning normally, the catalytic converter reaches high temperatures. For this reason do not park
the car over inflammable material, grass, dry leaves, pine needles, etc.: fire hazard.

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.

DEVICES FOR REDUCING DIESEL ENGINE EMISSIONS
Oxidising catalytic converter
This device converts the polluting substances in the exhaust gas (carbon monoxide, unburnt hydro-
carbons and particulates) into harmless substances, thus reducing the smokiness and smell associat-
ed with diesel engine exhaust fumes.
The catalytic converter consists of a stainless steel case containing a honeycomb ceramic core in
which there is the precious metal that carries out the catalysing action.
Exhaust Gas Recirculation (E.G.R.) system
This system recirculates or reuses part of the exhaust gas in a proportion which varies according to
engine operating conditions.
When necessary, it is used for the control of nitrogen oxide emissions.

Diesel engines
Use diesel fuel only.

Ignoring the above rules
may lead to fire. When functioning nor-
mally, the catalytic con-
verter reaches high tem-
peratures. For this reason, do not
park the car over inflammable
material (grass, dry leaves, pine
needles, etc.): fire hazard.
Do not allow anything to
be sprayed onto the cat-
alytic converter, lambda
sensor and exhaust pipe. Do not install other heat
shields and do not remove
those already fitted to the
catalytic converter and exhaust
pipe. Never run the engine with the
spark plugs disconnected even for
testing purposes. Do not warm up
the engine by letting it idle for a
while before moving off unless the
outside temperature is very low and,
even in this case, only do so for less
than 30 seconds.
If you have trouble starting, do not
keep turning the ignition key for
long periods. Be especially careful to
avoid bump starting the car by
pushing, towing or rolling downhill:
these are all manoeuvres that can
damage the catalytic exhaust sys-
tem. Use an auxiliary battery for
start-ups only.
If the engine begins to “lose its
smoothness” when travelling, con-
tinue your journey but reduce the
demands you are making on the
engine and have the car seen at a
Lancia Dealershipas soon as you
can.
When the instrument panel fuel
reserve warning light comes on, fill
up as soon as possible. A low level of
fuel can cause an uneven supply of
fuel to the engine with the inevitable
increase in the temperature of the
exhaust gas and serious damages to
the catalytic converter.

7) Start the engine.
8) When the engine has started,
remove the leads in the reverse order
to before: D, C, Band finally A.
IMPORTANT If the engine fails to
start after a few attempts, do not keep
turning the key but have the car seen
to at a Lancia Dealership.
9) Put the cover back on the bat-
tery positive terminal by fitting the
lock flanges in.
10) Put the cover back and retight-
en the knob.
11) Close the boot tailgate.IMPORTANTWhen the tailgate is
closed, the boot latch is not locked.
To lock it, turn the metal insert of
the key anticlockwise in the latch.
Do not carry out this
procedure if you lack
experience: if it is not
done correctly it can cause very
intense electrical discharges and
the battery might even explode.
Do not to put naked flames or
lighted cigarettes near the battery
and do not cause sparks: risk of
explosion and fire.
Never use a battery
charger to jump start the
engine: you could damage
the electronic system, with spe-
cial reference to ignition and
injection control unit.
BUMP STARTING
Do not bump start by pushing,
towing or coasting downhill. This
way of starting could cause a rush of
fuel into the catalytic converter and
damage it beyond repair.
Remember that ifthe engine is not
running, the brake booster and the
power steering will not work. You
therefore have to use considerably
more effort on both the brake pedal
and the steering wheel.
Never connect the nega-
tive terminals of the two
batteries directly: sparks
could ignite the flammable gas
from the battery. If the auxiliary
battery is installed on another
car, prevent accidental contact
between the metal parts of the
two vehicles.
