Starting
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 and
emissions. It is advisable to move off
immediately and slowly, avoiding
high speeds: in this way the engine
will warm up more quickly.
Unnecessary actions
Avoid accelerating when stopped at
traffic lights or before stopping the
engine.
This, as well as double declutching, is
absolutely unnecessary and increases
consumption and pollution.
Gear selection
As soon as the conditions of the
traffic and road permit, use a higher
gear.
Using a low gear for faster
acceleration will increase
consumption.
Improper use of a high gear
increases consumption, emissions
and engine wear.
Maximum speed
Fuel consumption increases
considerably with speed. Maintain a
constant speed, avoiding
unnecessary braking and
acceleration, which cost in terms of
both fuel and emissions.
Acceleration
Accelerating violently will greatly
affect consumption and emissions:
acceleration should be gradual.
CONDITIONS OF USE
The main usage conditions that
negatively affect fuel consumption
are listed below.
Cold starting
Short journeys and frequent cold
starts do not allow the engine to
reach optimum operating
temperature.
This results in a significant increase
in consumption levels (by 15–30% in
the urban cycle) and emissions.
Traffic and road conditions
Rather high consumption levels are
linked to situations with heavy
traffic, for instance when travelling in
queues with frequent use of the
lower gears or in cities with many
traffic lights. Winding mountain
roads and rough road surfaces also
adversely affect consumption.
Stopping in traffic
During prolonged hold-ups
(e.g. at level crossings) the engine
should be switched off.
