catalytic converter FIAT PUNTO 2018 Owner handbook (in English)

READ THIS CAREFULLY!

K
REFUELLINGPetrol engines : refuel only with unleaded petrol with an octane rating (RON) of no l\
ess than 95 conforming to
the European specification EN228.
Diesel engines: refuel only with diesel fuel conforming to the European specification \
EN590.
The use of other products or mixtures may damage the engine beyond repai\
r and consequently invalidate the war-
ranty, depending on the damage caused.
STARTING THE ENGINE Petrol engines : make sure that the handbrake is engaged, set the gearshift lever to ne\
utral, fully depress the clutch
without pressing the accelerator, then turn the ignition key to AVV and \
release it as soon as the engine has started.
Diesel engines: make sure that the handbrake is engaged, set the gearshift lever to ne\
utral, fully depress the clutch
without pressing the accelerator, then turn the ignition key to MAR and \
wait for the warning lights
Yand mto
go off; turn the ignition key to AVV and release it as soon as the engin\
e has started.
PARKING ON FLAMMABLE MATERIAL The catalytic converter develops high temperatures during operation. Do \
not park the vehicle on grass, dry leaves,
pine needles or other flammable material: fire hazard.
RESPECTING THE ENVIRONMENT The car is fitted with a system that allows continuous diagnosis of the \
components correlated with emissions to en-
sure better respect for the environment.

FUEL TANK CAP fig. 111
To carry out refuelling, open lid A and un-
screw cap B ; the cap is fitted with a de-
vice Cwhich fastens it to the lid so it can-
not be mislaid.
In some versions, cap B may be provided
with a lock and key; use the ignition key
to access the flap A, turn it anti-clockwise
and unscrew the cap itself.
The hermetic seal may cause a slight in-
crease in pressure in the tank. A suction
noise when you release the cap is there-
fore entirely normal.
When refuelling, hook the cap onto the
device inside the lid as shown in fig. 111.
fig. 111F0M0138m
Do not place naked flames
or lit cigarettes near to the
fuel tank opening: fire risk. Keep your
face away from the fuel tank open-
ing to avoid breathing in harmful
vapours.
WARNING
Filling the tank
To fill the tank completely, top up twice
after the first click of the trigger. Further
top ups could cause faults in the fuel sup-
ply system.
PROTECTING
THE ENVIRONMENT
The devices for reducing 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 following devices are used for reduc-
ing diesel fuel engine emissions:
❒oxidising catalytic converter;
❒exhaust gas recirculation system (E.G.R.);
❒diesel particulate filter (DPF) (for ver- sions/markets, where provided).

The catalytic converter
reaches high temperatures
during normal operation. Do not

WARNING
DIESEL PARTICULATE
FILTER (DPF)
(for versions/markets where provided)
The Diesel Particulate Filter is a mechan-
ical filter, integral with the exhaust system,
that physically traps particulates present
in the exhaust gases of diesel engines.
The diesel particulate filter is needed to
eliminate almost all particulates in com-
pliance with current/future legislation.
During normal use of the vehicle, the en-
gine control unit records a set of data (e.g.
travel time, type of route, temperatures,
etc.) and it will then calculate how much
particulate has been trapped by the filter.
Since this filter physically traps particu-
late, it should be regenerated (cleaned)
at regular intervals by burning the carbon
particles.
The regeneration procedure is handled
automatically by the engine control unit
according to the filter conditions and ve-
hicle use conditions. During regeneration, there may be: a lim-
ited increase in minimum revs, a slight in-
crease in fumes and high exhaust temper-
atures. These are not faults; they do not
impair vehicle performance or damage the
environment.
If the dedicated message is displayed, re-
fer to the “Warning lights and messages”
section.
The diesel particulate filter
(DPF) (for versions/markets,
where provided) reaches high tem-
peratures during normal operation.
Do not park the vehicle on grass, dry
leaves, pine needles or other flam-
mable material: fire hazard.

STARTING
AND DRIVING
❒turn the ignition key to AVV as soon
as the warning light
mturns off. Wait-
ing too long will waste the work done
by the heater plugs. Release the key as
soon as the engine starts.
If the engine does not start at the first at-
tempt, return the ignition key to STOP
before repeating the starting procedure.
If, when the ignition key is at MAR, the in-
strument panel warning light
Yremains
lit together with warning light
m, turn
the key to STOP and then back to MAR;
if the warning lights remain on, try using
the other keys provided with the car.
IMPORTANT If the instrument panel
warning light
Ystays on permanently,
contact a Fiat Dealership immediately.
IMPORTANT Never leave the ignition key
at MAR when the engine is off.
Warning light
mwill blink
for 60 seconds after starting
or during prolonged cranking
to indicate a fault with the
glow plug system. Use the car as nor-
mal if the engine starts, but go to a Fi-
at Dealership as soon as possible.
WARMING UP THE ENGINE
AFTER IT HAS JUST STARTED
(petrol and diesel versions)
Proceed as follows:
❒drive off slowly at medium revs, and ac- celerate smoothly;
❒do not demand maximum performancefor the first few kilometres. Wait until
the engine coolant gauge starts moving.
Remember that the brake
booster and power steering
are not operational until the
engine has been started, so
you need to apply much more force
than usual to the brake pedal and
steering wheel.
Never jump start the engine
by pushing, towing or driving
downhill. This could cause fu-
el to flow into the catalytic
converter and damage it beyond repair.
STOPPING THE ENGINE
Turn the ignition to STOP while the
engine is idling.
IMPORTANT After a long drive, you
should allow the engine to “catch its
breath” before turning it off by letting it
idle to allow the temperature in the en-
gine compartment to fall.
A quick burst on the acceler-
ator before turning off the en-
gine serves absolutely no
practical purpose; it wastes
fuel and is especially damaging to tur-
bocharged engines.

WARNING
LIGHTS AND MESSAGES
Go to a Fiat Dealership as
soon as possible if warning
light
Udoes not light up
when the key is turned to
MAR or if, while travelling, it either
comes on permanently or flashes
(along with a message on the display
on some versions). The operation of the
Uwarning light may be checked by
traffic police using appropriate equip-
ment. Respect the regulations in force
in the country where you are driving.
If the light flashes, come off the accelera-
tor pedal to reduce engine revs until the
warning light stops flashing; continue the
journey at moderate speed, trying to avoid
driving conditions that may cause further
flashing, and get to a Fiat Dealership as
soon as possible.
EOBD engine control
system failure
Under normal conditions, turning the ig-
nition key to MAR, the warning light turns
on but it should go off after the engine
starts. This indicates that the warning light
is working correctly. If the warning light ei-
ther stays on or comes on while travelling:
❒
on permanently: this means there is
a fault in the supply/ignition system
which could cause high exhaust emis-
sions, loss of performance, poor han-
dling and high fuel consumption levels.
A specific message is displayed on certain
versions.
Under these conditions, the vehicle can
continue travelling at moderate speed
without demanding excessive effort from
the engine. Prolonged use of the car with
the warning light on may cause damage.
Go to a Fiat Dealership as soon as possi-
ble. The warning light goes out after the
fault disappears, but the indication is
stored in the system.
❒ flashing: this indicates possible damage
to the catalytic converter (see “EOBD
system” in the “Dashboard and con-
trols” section).

Injection system failure
Under normal conditions, turning the ig-
nition key to MAR, the warning light turns
on but it should go off after the engine
starts.
If the warning light stays on or comes on
when travelling, it means there is a fault in
the injection system which could cause
loss of performance, poor handling and
high fuel consumption levels.
A specific message is displayed on certain
versions.
Under these conditions, the vehicle can
continue travelling at moderate speed
