catalytic converter Lancia Musa 2011 Owner handbook (in English)

USE OF ENVIRONMENTAL-FRIENDLY MATERIALS
All components of the LANCIA Musa are asbestos-free. Padding and the climate control system are free from CFC
(chlorofluorocarbon), the gases deemed responsible for the destruction of the ozone layer. Paint and bolt corrosion
protections are cadmium-free and safe for the air and water.
EMISSION REDUCTION DEVICES (petrol engines)
Three-way catalytic converter
The exhaust system is equipped with a catalyser made of noble metal alloys. It is accommodated in a stainless steel
container which can withstand high operating temperatures.
The catalyser converts unburnt hydrocarbons, carbon oxide and nitrogen oxides contained in exhaust gases (the
harmful gas content in exhaust is also limited by the electronic injection and ignition system), turning them into non-
polluting compounds.
Due to the high temperature reached during operation of the catalytic converter, it is advisable not to park the car over
flammable materials (paper, oil, dry grass, dry leaves, etc.).
Lambda sensors
The lambda sensors detect the oxygen content in exhaust gases. The signal transmitted by the lambda sensors is used
by the injection and ignition system electronic control unit to adjust the air-fuel mixture.
Anti-evaporation system
It is impossible to prevent the formation of petrol vapours, even when the engine is off. For this reason, a system has
been developed with traps the vapours in a special activate carbon canister.
The vapours are sucked in and burnt in the engine during operation.

EMISSION REDUCTION DEVICES (Multijet engines)
Oxidising catalytic converter
The device converts the polluting substances contained in exhaust gases (carbon oxide, unburnt hydrocarbons and
particulate) into harmless substances, reducing the smokiness and the typical smell of diesel engines.
The catalytic converter consists of a stainless steel metallic casing which contains a wasp nest ceramic body on which
the noble metal used for the catalysing action is applied.
Exhaust gas recirculation system (E.G.R.)
This device recirculates (i.e. reuses) part of the exhaust gases. The percentages depends on the conditions of use of the
engine.
It is used to control nitrogen oxide emissions, when needed.

VERY IMPORTANT
REFUELLING
Petrol engines:refuel with unleaded petrol with an octane rating (RON) of 95 or higher only.
Multijet engines:only refuel with diesel fuel conforming to the European specification EN590.
The use of other products or mixtures may damage the engine beyond repair and consequently cause lapse
of warranty in relation to the damage caused.
STARTING THE ENGINE
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 for the warning lights Yemto go out; turn
the ignition key AV Vand release it as soon as the engine starts.
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.
RESPECTING THE ENVIRONMENT
The car is fitted with a system that allows continuous diagnosis of the components correlated with
emissions to ensure better respect for the environment.

late how much particulates has been
trapped by the filter. Since this filter
physically traps particulate, it should
be regenerated (cleaned) at regular in-
tervals by burning carbon particles.
The regeneration procedure is con-
trolled automatically by the engine
management control unit according to
the filter conditions and vehicle use
conditions. The following phenomena
may occur during the regeneration:
limited increase of idle speed, activation
of electric fan, limited increase of
smoke, high temperatures at the ex-
haust. These are not faults; they do not
impair vehicle performance or damage
the environment. If the dedicated mes-
sage 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 sensor;
❒fuel evaporation system.
In addition, do not let the engine run,
even for a test, with one or more spark
plugs disconnected.
The devices for reducing diesel fuel en-
gine emissions are the following:
❒oxidising catalytic converter;
❒exhaust gas recirculation system
(E.G.R.);
❒diesel particulate filter (DPF)
DPF (DIESEL PARTICULATE
FILTER)
(for 1.3 Multijet 90 HP - 1.3 Multijet
95 HP 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 particular fil-
ter has been adopted to eliminate al-
most totally particulates in compliance
with current / future law regulations.
During normal use of the vehicle, the
engine control unit records a set of data
(e.g.: travel time, type of route, tem-
peratures, etc.) and it will then calcu- When refuelling, fasten the cap to the
device inside the flap as shown in the
diagram.
IMPORTANT The airtight sealing of
the tank may cause a slight vacuum.
A suction noise when you release the
cap is therefore entirely normal.
After refuelling, fasten the cap by
turning it clockwise until you hear it
click, then turn the key clockwise ad
remove the key from the flap.
Do not approach naked
flames or lit cigarettes 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

❒will light up on the instrument
panel; wait for warning lights
Yand
mto go out. This will hap-
pen faster when the engine is
warm;
❒press the clutch pedal all the way
down 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 With the engine cold,
the accelerator must be entirely re-
leased when turning the ignition key
to position AV V.
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 at MAR,
the instrument panel warning light
Yremains lit, turn the key to STOP
and then back to MAR; if the warn-
ing lights remain on, try with the
other keys provided with the car.
Contact a Lancia Dealership if you
still cannot start the engine.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. Accelerate
smoothly;
❒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 go to a Lancia Deal-
ership as soon as possible.
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. This could
cause a flow of fuel into the
catalytic converter and damage it
beyond repair.
A quick burst on the accel-
erator before turning off the
engine serves absolutely no
practical purpose, it wastes
fuel and is damaging especially to
turbocharged engines.
IMPORTANT Never leave the ignition
key to MARwhen the engine is off.
