DIESEL ENGINES
If the outside temperature is very low, the
diesel thickens due to the formation of paraf-
fins and could clog the diesel fuel filter.
In order to avoid these problems, different
types of diesel are distributed according to
the season: summer type, winter type arc-
tic type (mountains/cold areas).
If refuelling with diesel fuel not suitable for
the current temperature, mix diesel fuel with
TUTELA DIESEL ARTadditive in the pro-
portions stated on the can, putting first the
antifreeze in the tank and then the diesel
fuel.
TUTELA DIESEL ARTshall be added to
diesel fuel before the due to cold take place.
Adding it later will be worthless. If driving or
parking the vehicle for a long period in cold
areas/mountains, refuel with the diesel fu-
el available at local filling stations. In this
situation you are also recommended to have
in the tank an amount of fuel 50% higher
than usable capacity.
REFUELLING
PETROL ENGINES
Use only unleaded petrol.
To prevent accidentally filling with leaded
petrol, the diameter of the fuel tank filler
is of such a size as not to accept the noz-
zle of this type of petrol.
The unleaded petrol octane number
(R.O.N.) used shall not be less than 95.
IMPORTANTAn inefficient catalyst
leads to harmful emission at the exhaust,
thus environment pollution.
IMPORTANTUnder no circumstances
should conventional leaded petrol be used,
as this would irreparably damage the cata-
lyst.Cars with diesel engines
must only be filled with
diesel fuel for motor vehi-
cles, in compliance with European
Specification EN590. The use of
other products or mixtures may ir-
reparably damage the engine with
invalidation of the warranty due to
the damage caused. In the event of
accidentally filling with another
type of fuel, do not start the en-
gine and empty the tank. If the en-
gine has been run even for only a
very short time, in addition to the
tank, it is also necessary to drain
out the whole fuel circuit.

The devices used to reduce diesel fuel en-
gine emissions are:
– oxidising catalyst;
– exhaust gas recirculation system (E. G. R.);
– diesel particulate filter (DPF). DPF (Diesel Particulate Filter)
(for versions/ markets where
applicable)
The Diesel Particulate Filter is a mechani-
cal filter, integral with the exhaust system,
that physically traps particulates present in
the exhaust gases of Diesel engines.
The diesel particular filter has been adopt-
ed to eliminate almost totally particulates in
compliance with current / future law regu-
lations.
During normal use of the car, the engine
control unit records a set of data (e.g.: trav-
el time, type of route, temperatures, etc.)
and it will then calculate how much partic-
ulates has been trapped by the filter.
Since this filter physically traps particulates,
it shall be cleaned (reclaimed) at regular in-
tervals by burning carbon particles.
ENVIRONMENTAL
PROTECTION
The devices used to reduce petrol engine
emissions are:
– trivalent catalytic converter (catalytic si-
lencer);
– Lambda sensors;
– anti-evaporation system.
If one or more spark plugs are discon-
nected, do not run the engine, even for a
test.During normal service the
catalyst and the diesel par-
ticulate filter (DPF) reach
high temperatures. Do not there-
fore park the car over inflammable
materials (grass, dry leaves, pine
needles, etc.): fire hazard.

IN AN EMERGENCY
181
STARTING BY INERTIA
If the car is equipped with “Kit for tyre re-
pair Fix&Go“, see the instructions contained
in the following chapter.
GENERAL INSTRUCTIONS
As an alternative to the FIX & GO, the car
can be provided (upon request) with space-
saver spare wheel or standard wheel; wheel
changing and correct use of the jack call for
some precautions as listed below.
IN THE EVENT OF A PUNCTURE
Never push, tow or coast
start the car. This could
cause fuel to flow into the
catalyst damaging it irreversibly.
Remember that the en-
gine brake and power
steering are not opera-
tional until the engine is started,
therefore, much greater effort than
usual is needed on the brake ped-
al and steering wheel.
Signal the presence of the
stationary car according to
current regulations: hazard
warning lights, reflecting triangle
etc.. Any passengers should leave
the car and wait for the wheel to be
changed out of harm of the traffic.
If parked on a slope or rough sur-
face, chock the wheels with
wedges or other suitable devices
to prevent the car from rolling.
Never start the engine
with the car jacked.
When driving with a trail-
er, disconnect the trailer before
raising the car. The compact spare
wheel is specific to your car, do not
use it on other models, or use the
spare wheel of other models on
your car.
Should the type of wheels used
be changed (alloy rims instead of
steel), it is also necessary to
change the whole set of fastening
bolts with others of suitable size.
The compact spare wheel is nar-
rower than normal wheels, it
should be used only for the dis-
tance necessary to reach a service
point to have the punctured tyre
repaired and, during its use, the car
speed must not exceed 80 km/h.

FUEL CONSUMPTION
The fuel consumption figures given in the
table below are determined on the basis of
the homologation tests set down by specif-
ic European directives.
The procedures below are followed for
measuring consumption:
–urban cycle: cold starting followed by
driving that simulates urban use of the car;–extra-urban cycle: frequent accel-
erating in all gears, simulating extraurban
use of the car; the speed varies between 0
and 120 km/h;
–combined consumption: is calcu-
lated weighing about 37% of urban cycle
consumption and about 63% of extraurban
consumption.
