FUEL CONSUMPTION
The fuel consumption and CO2emis-
sion values listed in the table below are
determined based on homologation
tests laid down in the European Di-
rective 2004/3/EC.
To measure fuel consumption and
emissions the procedures below are
followed:
– Urban cycle:the vehicle is start-
ed with the engine cold and driven so
as to reproduce the speed and
gearshift profile specified in the Euro-
pean Directive. The cycle includes a
series of accelerations, decelerations,
driving at constant speed and standing
with the engine in idle. The maximum
speed reached during the cycle is
50km/h and the average speed is
19km/h.– Extraurban cycle:consecutive to
the urban cycle according to the spec-
ifications laid down in the European
Directive. The maximum speed
reached during the cycle is 120km/h
and the average speed is 63km/h.
– consumption:this is determined
through a weighted average of the
consumption measured for the urban
cycle (with approx. 37% weight) and
for the extraurban cycle (with approx.
63% weight).
IMPORTANT
In practice, fuel consumption may be
higher than the values determined
through the homologation tests. Be-
low are some of the main factors that
may result in a deviation between the
consumption measured during normal
use of the vehicle and that measured
during the homologation tests.1) Vehicle conditions: inadequate
maintenance, use of roof racks, trail-
ers, heavy load conditions, intense use
of the electrical devices and the air-
conditioning.
2) Driving style: frequent cold starts
to drive short stretches, incorrect
procedure to warm up the engine,
gearshifting, continuous driving at high
speeds, sudden acceleration and brak-
ing.
3) Traffic and road conditions: driving
in traffic, uphill or twisty roads, road
surface conditions.
4) Atmospheric conditions: intem-
perate climate, wind, rain, snow, dri-
ving at high altitudes.
5) Percentage town, out-of-town and
motorway driving.

PRACTICAL TIPS TO
REDUCE CONSUMPTION
AND ENVIRONMENTAL
POLLUTION
Vehicle conditions
1. Have checks and adjustments
carried out in accordance with the
“Scheduled Service Plan”.
2. Check the tyre pressure at inter-
vals of not more than 4 weeks (see
“Tyre pressure”). Too low tyre pres-
sure increases consumption as the
rolling resistance increases. In these
conditions the tyres wear faster and
performance deteriorates.
3. Use winter tyresonly in the sea-
sons where dictated by the climatic
conditions. Winter tyres not only in-
crease consumption but also tyre
noise.4. Do not travel in heavy load con-
ditions(vehicle overloaded): The
weight of the vehicle (especially when
driving in town) and its trim greatly af-
fect fuel consumption and stability.
5. Remove roof racks or ski racks
after use. These accessories reduce
the aerodynamics of the vehicle and
have a negative effect on fuel con-
sumption.
6. Ideally use a trailerto transport
particularly bulky objects.
7. It is preferable to use the air vents:
driving with the window open has a
negative effect on the aerodynamics of
the vehicle.
8. Use the electrical devices only for
the time strictly necessary. The rear
heated window, additional headlights,
windscreen wipers and heater fan
need a considerable amount of ener-
gy, consequently increasing fuel con-
sumption (up to 25% more in the ur-
ban cycle).9. Using the air-conditioning in-
creases consumption (up to 30% more
on average): use the air vents when
the outside temperature permits.
Driving style
1. After starting the engineit is
advisable to set off immediately and
slowly avoiding revving up the engine.
Do not warm up the engine with the
vehicle stationary either at idle or at
high speed: in these conditions the en-
gine in fact warms up more slowly, in-
creasing consumption, emissions and
wear of the mechanical devices.
2. Avoid revving upwhen starting
at traffic lights or before turning off the
engine. This action, like double-de-
clutching, is unnecessary and causes in-
creased fuel consumption and pollu-
tion.
