FUEL CAP
The fuel cap (C-fig. 164) is electrically
controlled. To open it, press button (D-
fig. 165); the flap can be opened only
when the engine is off.
The fuel cap (A-fig. 164), accessible af-
ter opening the lid (C), is fitted with a catch
to prevent losing it (B) which fastens it to the
lid.
When refuelling, hook the cap to the de-
vice on the inner flap, as illustrated.
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.
IMPORTANT An inefficient catalyst
leads to harmful emission at the exhaust,
thus environment pollution.
IMPORTANTNever put leaded petrol,
even in small quantity, in the tank, even if
it is an emergency. This would irreversibly
damage the exhaust gas catalyst.
JTD ENGINES
At low temperatures the degree of fluidi-
ty of fuel oil may become insufficient due to
the formation of paraffins leading to mal-
functioning of the fuel system.
Therefore, to avoid inconveniences, sum-
mer and winter fuel oils are normally dis-
tributed depending on the season.
In the event the car is filled with fuel oil
unsuitable for the using temperature, mix
it with DIESEL MIX additive in the propor-
tions stated on the can, firstly putting the
antifreeze in the tank and then the fuel oil.
The vehicle must only be
filled with fuel oil for mo-
tor vehicles, in compliance
with European Specification
EN590. The use of other products
or mixtures may irreparably dam-
age the engine with invalidation of
the warranty due to the damage
caused. In the event of accidental-
ly filling with another type of fuel,
do not start the engine and empty
the tank. If the engine has been run
even for only a very short time, in
addition to the tank, it is also nec-
essary to empty the whole supply
circuit.

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.
The devices used to reduce diesel fuel en-
gine emissions are:
– oxidising catalyst;
– exhaust gas re-circulation system
(E. G. R.). Do not go near the fuel
filler with naked flames or
lit cigarettes: danger of
fire. Avoid going too near the fuel
filler with your face, to avoid in-
haling harmful vapours.
In the case of need, only
replace the fuel cap with
another genuine one, or the
efficiency of the fuel vapour re-
covery system could be adversely
affected.
Should it be not possible to open the fuel
flap electrically, use the special cable in the
boot (A-fig. 166) to open it manually.
Due to the high tempera-
tures reached during oper-
ation of the catalytic si-
lencer the vehicle should not be
parked over inflammable materials
(grass, dry leaves, pine needles,
etc.).

IMPORTANTThe sealing of the tank
may cause light pressurising. A little breath-
ing off, while slackening the cap is ab-
solutely normal.
After refuelling, turn the cap clockwise and
close the flap.
IMPORTANTFor your safety, before
starting the engine, also make sure that the
fuel nozzle is correctly inserted in the fuel
distributor.
