2008 Lancia Musa catalytic converter

USE OF ENVIRONMENT-FRIENDLY MATERIALS
None of the components installed on LANCIA Musa contains asbestos. The padding and air conditioning system are
CFC-free (Chlorofluorocarbons), these gases being reliable for the depletion of the ozone layer. Dying agents and anti-
corrosion coating of the bolts and screws no longer contain cadmium, which pollutes the air and waterbeds.
EMISSION-REDUCING DEVICES (petrol engines)
Three-way catalytic converter (catalytic converter)
The exhaust system features a catalyst made with alloys of noble metals. It is installed in a stainless steel housing which
is resistant to high operating temperatures.
The catalyst converts the unburnt hydrocarbons, carbon oxide and nitrogen oxides that are present in the exhaust gases
(although in small quantities thanks to electronic injection ignition systems) into non-polluting compounds.
As the catalytic converter reaches high temperatures during car operation, we recommend that the car should not be
parked on materials that may pose a risk of flammability (e.g. paper, fuel oils, dry grass or leaves, etc.).
Lambda sensors
These sensors (Lambda) detect the oxygen content in the exhaust gases. Lambda sensors produce a signal which is
used by the electronic control unit of the injection and ignition system for regulating the air-fuel mix.
Fuel evaporation system
Even when the engine is not running, it is not possible to prevent the formation of petrol vapours. For this reason, a
system has been developed to “catch” these vapours in a special activated carbon vessel.
While the engine is running, these vapours are aspirated and delivered to combustion.

EMISSION-REDUCING DEVICES (Multijet engines)
Oxidising catalytic converter
It is used to convert the polluting substances in the exhaust gases (carbon oxide, unburnt hydrocarbons and
particulate) into harmless substances by reducing the smoke opacity index and the typical smell of exhaust gases
produced by diesel engines.
The catalyst converter comprises a stainless steel metal enclosure which contains a ceramic honey-comb body on which
the noble metal, having a catalyst function, is installed.
Exhaust gas recirculation system (E.G.R.)
It is used to recirculate, i.e. recycle, a portion of the exhaust gases in percentage terms that change according to the
engine operating conditions.
When necessary, it is used to check the emissions of nitrogen oxides.

MUST BE READ!
REFUELLING
Petrol engines:exclusively refuel the car with unleaded petrol having a RON that must not be below 95.
Multijet engines:exclusively refuel the car with vehicle propulsion diesel fuel conforming to the
European specification EN590.
The use of other products or mixtures may damage the engine beyond repair and consequently cause the
warranty to be void depending on the damage caused.
ENGINE STARTING
Petrol engines:make sure that the handbrake is engaged; set the gearshift lever to neutral; fully depress
the clutch without pressing the accelerator, then turn the ignition key to AV Vand release it as soon as the
engine has started.
Multijet engines:turn the ignition key to MARand wait until the warning lights Yandmgo off.
Then , turn the ignition key to AV Vand release it as soon as the engine has started.
PARKING ON FLAMMABLE MATERIAL
The catalytic converter develops high temperature during operation. Do not park on grass, dry leaves,
pine needles or other flammable material: fire risk.
ENVIRONMENTAL PROTECTION
The car is fitted with a system that allows continuous diagnosis of the emission-related components to
ensure better respect of the environment.

peratures, etc.) and it will then calcu-
late the amount of particulates trapped
by the filter. Since this filter physically
traps particulates, it shall be cleaned
(reclaimed) at regular intervals by
burning carbon particles. The regener-
ation procedure is controlled automat-
ically by the engine control unit ac-
cording to the filter conditions and the
conditions of use of the car. During the
regeneration procedure, the following
situations may occur: limited increase
of idle speed, activation of electric fan,
limited increase of smoke, high tem-
peratures at the exhaust. These are not
anomalies; they do not impair car be-
haviour and the environment. If the
dedicated message is displayed, refer to
section “Warning lights and messages”.PROTECTING THE
ENVIRONMENT
The devices for curtailing petrol engine
emissions are the following:
❒three-way catalytic converter;
❒Lambda sensors;
❒fuel evaporation prevention system.
In addition, do not let the engine run,
even for a test, with one or more spark
plugs disconnected.
The devices for curtailing diesel fuel en-
gine emissions are the following:
❒oxidising catalytic converter;
❒exhaust gas recirculation system
(E.G.R.);
❒diesel particulate filter (DPF)
DIESEL PARTICULATE
FILTER (DPF)
(for 1.3 Multijet 90 CV versions)
The Diesel Particulate Filter is a me-
chanical filter, integral with the exhaust
system, that physically traps particu-
lates present in the exhaust gases of
Diesel engines. The diesel particulate
filter has been adopted to eliminate al-
most totally particulates in compliance
with current / future law regulations.
During normal use of the car, the en-
gine control unit records a set of data
(e.g.: travel time, type of route, tem- During refuelling, attach the cap to
the device on the inside of the flap, as
shown in the figure.
IMPORTANT The sealing of the tank
may cause light pressuring in the
tank. A little breathing off, while
slackening the cap, is absolutely nor-
mal.
After refuelling, tighten the cap by
turning it clockwise until you hear one
or more clicks. Then turn the key
clockwise and remove it and close the
flap.
Do not place naked flames
or lit cigarettes near to the
fuel filler: fire risk. Keep your face
away from the fuel filler to prevent
breathing in harmful vapours.
WARNING
The catalytic converter de-
velops high temperature
during operation. Do not park on
grass, dry leaves, pine needles or
other flammable material: fire
risk.

STARTING
AND
DRIVING
❒turn on; wait for the warning light
Yand
mto turn off (the hot-
ter the engine the shorter the time
it takes to turn off);
❒press the clutch pedal down to the
floor without touching the accel-
erator;
❒turn the ignition key to AV Vas
soon as the warning light
mturns
off. Waiting too long will waste the
work done by the glow plugs. Re-
lease the key as soon as the engine
starts.
IMPORTANT When the engine is
cold, rotating the ignition key to AV V,
the accelerator pedal must be com-
pletely released.
If the engine does not start at the first
attempt, return the ignition key to
STOP before repeating starting.
If, when the ignition key is on MAR,
the instrument panel warning light
Yremains on, turn the key to STOP
and then back to MAR; if the warn-
ing light remains on, try with the
other keys provided with the car.
If you still cannot start the engine,
contact the Lancia Dealership.HOW TO WARM UP THE
ENGINE AFTER IT HAS JUST
STARTED (petrol and Multijet
engines)
Proceed as follows:
❒drive off slowly, letting the engine
turn at medium speed. Do not ac-
celerate abruptly;
❒do not demand maximum perfor-
mance for the first few kilometres.
Wait until the engine coolant
gauge starts moving.Warning light
mwill
blink for 60 seconds after
starting or during pro-
longed cranking to indicate
a fault to the glow plug heating sys-
tem. Use the car normally if the en-
gine starts and contact the Lancia
Dealership as soon as possible.
EMERGENCY START
If the instrument panel warning light
Ystays on steadily, you can perform
emergency start using the code on the
CODE card (see chapter “In an emer-
gency”).
STOPPING THE ENGINE
Turn the ignition to STOPwhile the en-
gine is idling.
IMPORTANT After a taxing drive,
you should allow the engine to “catch
its breath” before turning it off by let-
ting it idle to allow the temperature in
the engine compartment to fall.
Never jump start the engine
by pushing, towing or dri-
ving downhill. These ac-
tions could cause the fuel to
flow into the catalytic converter and
damage it beyond repair.
Revving up before stopping
the engine is useless, it
causes unnecessary fuel
consumption and can dam-
age the engine, in particular engines
equipped with turbocharger.
IMPORTANT With engine off, do not
leave the key in the ignition switch on
MAR.
