FUELOnly use unleaded premium fuel with an octane
number (R.O.N.) of no less than 95.
Tank capacity: approx. 86 litres, including a 14
litre reserve.WARNING: The anti-pollution devices of the
vehicle require unleaded fuel to be used at
all times. Under no circumstance, not even in
emergency situations, should leaded fuel be
supplied to the fuel tank, not even a minimum
quantity. You would irreparably damage the
catalytic muffler.
WARNING: An inefficient catalytic muffler results
in noxious exhaust emissions which are harmful
for the environment.
ENGINE OILTo check the level, please consult the
“Maintenance” section.
Do not top up with oil having characteristics other
than those of the oil already used.
The gap between the MIN and MAX reference
marks on the dipstick corresponds to about 1.5
litres of oil.
Use SAE 5W/40 API SL/CF and ACEA A3, B3,
B4 oil for fuel-powered engines.

FUEL
CONSUMPTIONThe fuel consumption values shown in the
following table were established based on
homologation tests prescribed by specific
European Directives.
The test procedures followed for fuel
consumption measuring are described below:
- City cycle: This test begins with a cold start,
followed by simulation of an urban route;
- Highway cycle: This test involves frequent
accelerations in all gears, simulating use of
the vehicle on routes outside urban areas;
the speed varies between 0 and 120 km/h
- Average fuel consumption: This is
calculated considering a route consisting
of about 37% city cycle and 63% highway
cycle.FUEL CONSUMPTION FOLLOWING THE 2004/3/EC
DIRECTIVE (LITRES PER 100 KM)
City Highway Average
23.6 11.4 15.8WARNING: The type of route, traffic and weather conditions, driving style, general condition of the
vehicle, equipment/accessories in the vehicle, use of the air conditioning system, vehicle load and other
items or situations which may negatively affect the vehicle aerodynamics or wind resistance lead to
consumption ratios differing from the indicated ones.CO
