Saving Fuel - Fiat Doblo Owner's Handbook Manual

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 maintenance carried out
in accordance with the "Scheduled
servicing plan".
❒ Check tyre pressure 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 use snow tyres when
the weather conditions make them
absolutely necessary. They increase
consumption and noise.
❒ Do not travel with a heavy load: the
weight of the vehicle (especially when
driving in town) and its geometry
greatly affect fuel consumption and
stability.
❒ Remove roof 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 a trailer if 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.
