IMPORTANT
22) For diesel engines, use only
diesel fuel for motor vehicles
in accordance with EN590
European specifications. The use
of other products or mixtures
may damage the engine beyond
repair and consequently invalidate
the warranty, due to the damage
caused. If you accidentally refuel
with another type of fuel, do not
start the engine, and drain the
tank. If the engine has run, even
for a very short time, you will need
to have the entire fuel supply
system emptied in addition to the
tank.
23) Do not bring naked flames or lit
cigarettes near the fuel tank filler:
fire risk. Keep your face away
from the fuel filler to prevent
breathing in harmful vapours.
SAVING FUEL
Some useful tips are given below for
fuel saving and reducing harmful
emissions of CO2 and other
pollutants (nitrogen oxides, unburnt
hydrocarbons, Particulate Matter
(PM), etc.).
PRACTICAL ADVICE
FOR REDUCING FUEL
CONSUMPTION AND
HARMFUL EMISSIONS
Vehicle conditions
❒Have checks and adjustments for
vehicle maintenancecarried out
in accordance with the “Scheduled
servicing plan”.
❒Checktyrepressure regularly, at
least once every four weeks.
Excessively low pressures will
increase consumption because
rolling resistance will be higher. In
addition, this wears the tyre more
quickly and impairs performance.
❒Only usesnow tyreswhen
the weather conditions make them
absolutely necessary. They increase
consumption and noise.❒Do not travel witha heavy load: the
weight of the vehicle (especially when
driving in town) and its geometry
greatly affect fuel consumption and
stability.
❒Removeroof racks or ski racks
after use. These accessories reduce
the vehicle's aerodynamic
penetration and have a negative
effect on fuel consumption.
❒When transporting particularly large
objects, use atrailerif possible.
❒Use the vehicle's air vents if possible:
travelling with the windows open
impairs aerodynamics.
❒Use electrical devices only for the
amount of time needed. The vehicle’s
heated rear window, additional
headlights, screen wipers and heater
fan require a considerable amount
of energy; this increases fuel
consumption (by up to +25% in an
urban cycle).
❒Air conditioning leads to higher fuel
consumption (on average up to
+30%). If the temperature outside is
not too extreme, try and use the
air vents.

STARTING AND DRIVING

FUEL
CONSUMPTION
The fuel consumption figures given
in the tables below are determined
on the basis of the type-approval
tests laid down by specific European
Directives.
These consumption values refer to
basic vehicles without optionals.
The procedures below are followed
for measuring consumption:
❒urban cycle: begins with cold
starting, followed by driving
simulating the use of the vehicle in
town;
❒extra-urban cycle: driving that
simulates using the vehicle out of
town with frequent acceleration in all
gears; the speed varies from 0 to 120
km/h;
❒combined consumption: calculated
with a weighting of approximately
37% of the urban cycle and 63% of
the extra-urban cycle.
IMPORTANT The type of route,
traffic situations, weather conditions,
driving style, general conditions of
the vehicle, trim level/equipment/
accessories, climate control system,
vehicle load, roof rack, other
situations that affect air drag may
lead to different fuel consumption
levels than those measured.
IMPORTANT
In practice, fuel consumption may
be higher than the values obtained
during the approval tests.
Here are some of the major factors
that can lead to a difference
between test and real consumption.
1) Vehicle condition: inadequate
servicing, use of roof racks, trailers,
heavy loading, high usage of
electrical devices and the
air conditioning.
2) Driving style: frequent cold starts
for short journeys, poor engine
warming technique, gear selection,
high speeds, sudden acceleration
and braking.3) Traffic and road conditions:
driving in traffic, steep hills or
winding roads, road surface
conditions.
4) Atmospheric conditions:
intemperate weather, wind, rain,
snow, high altitude.
5) Proportion of use in towns and
cities, in the country and on
motorways.

4. Do not travel with a heavy load:
the weight of the vehicle (especially
when driving in town) and its trim
greatly affect fuel consumption and
stability.
5. Remove roof racks or ski racks
after use. These accessories reduce
the vehicle's aerodynamic
penetration and have a negative
effect on fuel consumption.
6. When transporting particularly
large objects, use a trailer if
possible.
7. Use the vehicle's air vents if
possible: travelling with the windows
open impairs aerodynamics.
8. Use electrical devices only for the
amount of time needed. The
vehicle’s heated rear window,
additional headlights, screen wipers
and heater fan require a
considerable amount of energy;
increasing the current uptake
increases fuel consumption (by up
to +25% in an urban cycle).
9. Air conditioning leads to higher
fuel consumption (on average up to
+30%). If the temperature outside
is not too extreme, try and use
the air vents.Driving style
1. After starting the engine you
should drive away immediately and
slowly, avoiding high revs. Do not
warm up the engine at low or high
revs when the vehicle is stationary;
this causes the engine to warm
up more slowly, thereby increasing
fuel consumption, emissions and
mechanical component wear.
2. Avoid pointless actions such as
revving up when at traffic lights
or before stopping the engine. The
latter action, like double-
declutching, is unnecessary and
causes increased fuel consumption
and pollution.
3. Gear selection: select a high gear
as soon as possible (taking into
account normal engine operation
and traffic conditions) without
pushing the engine to high revs
during the intermediate gears. Using
low gears at high revs to get lively
acceleration increases fuel
consumption, harmful emissions
and engine wear.4. Vehicle speed: fuel consumption
increases exponentially as the speed
of the vehicle increases. Keep your
speed moderate and as even as
possible, avoiding unnecessary
braking and acceleration, which
cause excessive fuel consumption
and increased emissions. Keeping a
safe distance from the vehicle in
front helps to maintain a steady
speed.
5. Acceleration: accelerating
violently severely affects
consumption and emissions.
Acceleration should be gradual and
should not exceed the maximum
engine torque rate.
