REFUELLING

The anti-pollution devices
present on the vehicle im-
pose the use of four-star
unleaded fuel with an octane num-
ber (R.O.N.) above 95.
Under no circumstances
should conventional leaded
petrol be used, as this
would irreparably damage the cat-
alyst. If the tank is accidentally
filled with leaded fuel, even in
minute quantities, DO NOT START
THE ENGINE. Do not attempt to di-
lute the petrol with lead free fuel.
Drain the entire fuel circuit and
tank.
In order to prevent the vehicle being filled
with leaded petrol, the diameter of the filler
neck is smaller than the nozzle used on
pumps delivering leaded petrol.
If the catalyst is not
working properly, harmful
emissions reach the ex-
haust, resulting in environment pol-
lution.
