MUST BE READ!REFUELLING
Petrol engines:only refuel with unleaded petrol with octane rating (RON) no less than 95.
Diesel engines:only refuel with diesel fuel conforming to the European specification EN590.

ENGINE START-UP
Petrol engines with mechanical transmission:make sure the handbrake is pulled; put the gear lever into neutral;
press the clutch pedal down to the floor without touching the accelerator, then turn the ignition key to AV Vand release it as
soon as the engine starts.
Petrol engines with Selespeed transmission or Q-System:keep the brake pedal fully depressed; turn the igni-
tion key to AV Vand release it as soon as the engine has started; the transmission sets to neutral automatically (the display
shows position N).
Diesel engines:Turn the ignition key to MARand wait for the
Y
and
m
warning lights to go off; turn the ignition
key to AV Vand release it as soon as the engine starts.
PARKING OVER FLAMMABLE MATERIAL
While functioning normally, the catalytic converter reaches high temperatures. For this reason do not park the car over in-
flammable material, grass, dry leaves, pine needles, etc.: fire hazard.


GETTING TO KNOW YOUR CAR
185
REFUELLING PETROL ENGINESIn 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.At low temperatures, the degree of fluid-
ity of fuel oil may become insufficient due
to the formation of paraffins leading to dan-
ger of clogging the fuel oil filter.
Therefore, to avoid inconveniences, sum-
mer and winter fuel oils are normally dis-
tributed depending on the season.
However, during the intermediate season,
characterised by a large difference between
outside temperatures (0°C to 15°C), the
quality of the fuel oil distributed to the
pumps may not be adequate.
In this case, and above all if the use of the
car involves stopping and then starting again
at low temperatures (e.g. mountains),
make sure the car is filled with winter fuel
oil; if not, you are advised to mix the fuel
oil with a DIESEL MIXadditive in the pro-
portions stated on the can, pouring first the
antifreeze and then the fuel oil into the tank.
TheDIESEL MIXantifreeze should be
mixed with the fuel oil before reactions due
to cold take place. Adding it too late will
prove pointless. 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.
If the catalyst is not
working properly, harmful
emissions reach the ex-
haust, resulting in environment pol-
lution.The car must be refuelled
only with fuel oil for motor
vehicles, in conformity with
European specification EN590. The
use of other products or mixtures
may damage the engine irrepara-
bly, resulting in invalidation of the
warranty for the damage caused.
If the tank is accidentally filled
with another type of fuel, do not
start the engine but drain the tank.
If the engine has been run even for
a brief period, the tank must be
drained together with the entire
fuel circuit.
