DIESEL ENGINES
Operation at low temperatures
If the outside temperature is very low, the
diesel thickens due to the formation of
paraffin clots with consequent anomalous
operation of the fuel supply system.
In order to avoid these problems, different
types of diesel are distributed according to
the season: summer type, winter type and
arctic type (cold, mountain areas). If refu-
elling with diesel fuel whose features are not
suitable to the temperature of use, it is ad-
visable to mix TUTELA DIESEL ART addi-
tive in the proportions shown on the con-
tainer with the fuel. Pour the additive in-
to the tank before the fuel.
When using or parking the vehicle for a
long time in the mountains or cold areas,
it is advisable to refuel using locally avail-
able fuel.
In this case, it is also advisable to keep the
tank over 50% full.For diesel engines, use diesel
fuel for motor vehicles com-
pliant with EN590 European
specifications only. The use of
other products or mixtures may dam-
age the engine beyond repair and con-
sequently cause lapse of warranty in
relation to the damage caused. If you
accidentally introduce other types of
fuel in the tank, do not start the engine
and empty the tank. If the engine has
run also for a very short time, you will
need to have the entire fuel feed sys-
tem emptied in addition to the tank.
REFUELLING CAPACITY
To fill the tank completely, top-up twice
after the pump switches off. Further top-
ups could cause faults in the fuel feeding
system.

Opening
1) Open the flap A - fig. 97pulling it out-
wards, keep the cap Bstill, insert the ig-
nition key in the lock and turn it anti-
clockwise.
2) Turn the cap anti-clockwise and extract
it. The cap has a device Cretaining it to
the flap so it cannot be lost. When refill-
ing, attach the cap to the flap, as illustrat-
ed.
Closing
1) Fit the cap (complete with key) and turn
it clockwise until it clicks once or more.
2) Turn the key clockwise and extract it,
then close the flap.

ENVIRONMENTAL
PROTECTION
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) (where
provided). Do not place free flames or lit
cigarettes near to the fuel
filler: this may pose a risk of
fire. Keep your face away
from the fuel filler to prevent breath-
ing in harmful vapours.
DIESEL PARTICULATE
FILTER DPF
(Diesel Particulate Filter)
(for versions/markets, where provided)
The Diesel Particulate Filter is a mechan-
ical filter integral with the exhaust system
that physically traps carbon particles pre-
sent in the exhaust gases of Diesel engines.
The diesel particulate filter has been
adopted to eliminate particulates almost
totally 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,
temperatures, etc.) and it will then calcu-
late the amount of particles trapped by the
filter.
Since this filter physically traps particulates,
it shall be cleaned (reclaimed) at regular
intervals by burning carbon particles. The
regeneration procedure is controlled au-
tomatically by the engine control unit ac-
cording to the filter conditions and the
conditions of use of the vehicle.
During the regeneration procedure, the
following situations may occur: limited in-
crease of idle speed, activation of electric
fan, limited increase of smoke, high tem-
peratures at the exhaust. These events
must not be considered as a malfunction-
ing: they do not impair vehicle behaviour
and the environment. If the dedicated
message is displayed, refer to section
“Warning lights and messages”. 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.
