05 During your journey
Fuel
tinuously controls the injectors. The ratio of fuel
to air directed to the engine is continuously
adjusted. These adjustments create optimal
conditions for efficient combustion, and
together with the three-way catalytic converter
reduce harmful emissions (hydrocarbons, car-
bon monoxide and nitrous oxides).
Bioethanol E85
Do not modify the fuel system or its compo-
nents, and do not replace components with
parts that are not specifically designed for use
with bioethanol.
WARNING
05
Methanol must not be used. A decal on the
inside of the fuel filler flap shows the correct
alternative fuel.
The use of components not designed for
bioethanol engines could cause fire, injury
or engine damage.
Reserve fuel can
The reserve fuel can should be filled with petrol,
see page 97.
1 Diesel fuel may contain a certain amount of RME, but further amounts must not be added.

WARNING
Ethanol is sensitive to sparks, and explosive
gases could form in the reserve fuel can if it
is refuelled with ethanol.
Diesel
Diesel must fulfil the EN 590 or JIS K2204
standards. Diesel engines are sensitive to con-
taminants, such as excessively high volumes
of sulphur particles for example. Only use die-
sel fuel from well-known producers. Never use
diesel of dubious quality.
At low temperatures (-40 °C to -6 °C), a paraffin
precipitate may form in the diesel fuel, which
may lead to ignition problems. Special diesel
fuel designed for low temperatures around
freezing point is available from the major oil
companies. This fuel is less viscous at low tem-
peratures and reduces the risk of paraffin pre-
cipitate.
The risk of condensation in the fuel tank is
reduced if the tank is kept well filled. When
refuelling, check that the area around the fuel
filler pipe is clean. Avoid spilling fuel onto the
paintwork. Wash off any spillage with deter-
gent and water.
IMPORTANT
Only ever use fuel that fulfils the European
diesel standard.
The sulphur content must be a maximum of
50 ppm.
IMPORTANT
Diesel type fuels which must not be used:
•
Special additives
•
Marine Diesel Fuel
•
Fuel oil
•
1
RME (Rape Methyl Ester) and vegeta-
ble oil.
These fuels do not fulfil the requirements in
accordance with Volvo recommendations
and generate increased wear and engine
damage that is not covered by the Volvo
warranty.
Empty tank
No special procedures are required if the tank
runs dry. The fuel system is bled automatically
if the remote control is kept in key position II
(see page 70) for approx. 60 seconds before
the start attempt.
