IMPORTANT
•Always refuel with unleaded petrol so as
not to damage the catalytic converter.
•Do not use additives not recommended
by Volvo.
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
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 canThe reserve fuel can should be filled with petrol,
see the NOTE box, page 118.
IMPORTANT
Make sure the reserve fuel can is securely
fastened and that its cap is sealed.
WARNING
Ethanol is sensitive to sparks, and explosive
gases could form in the reserve fuel can if it
is refuelled with ethanol.
Diesel
Only use diesel fuel from well-known produc-
ers. Never use diesel of dubious quality. Diesel
should fulfil the EN 590 or JIS K2204 stand-
ards. Diesel engines are sensitive to contami-
nants in the fuel, such as excessively high vol-
umes of sulphur particles for example.
At low temperatures (-6 °C to -40 °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. Whenrefuelling, 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 that must not be used:
•Special additives
•Marine diesel fuel
•Heating oil
•FAME1 (Fatty Acid Methyl Ester) and
vegetable 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 tankThe design of the fuel system in a diesel engine
means that if the vehicle runs out of fuel, the
1Diesel fuel may contain a certain amount of FAME, but further amounts must not be added.

tank may need to be vented in the workshop in
order to restart the engine after fuelling.
Once the engine has stopped due to fuel star-
vation, the fuel system needs a few moments
to carry out a check. Do this before starting the
engine, once the fuel tank has been filled with
diesel:
1. Insert the remote control key in the ignition
switch and push it in to the end position
(see page 78).
2.
Press the START button without depress-
ing the brake and/or clutch pedal.
3. Wait approx. 1 minute.
4. To start the engine: Depress the brake and/
or clutch pedal and then press the
START button again.
NOTE
Before filling with fuel in the event of fuel
shortage:
•Stop the car on as flat/level ground as
possible - if the car is tilting there is a
risk of air pockets in the fuel supply.
Draining condensation from the fuel filterThe fuel filter separates condensation from the
fuel. Condensation can disrupt engine opera-
tion.The fuel filter must be drained at the intervals
specified in the Service and Warranty Booklet
or if you suspect that the car has been filled
with contaminated fuel.
IMPORTANT
Certain special additives remove the water
separation in the fuel filter.
Diesel particle filter (DPF)Diesel cars are equipped with a particle filter,
which results in more efficient emission con-
trol. The particles in the exhaust gases are col-
lected in the filter during normal driving. So-
called "regeneration" is started in order to burn
away the particles and empty the filter. This
requires the engine to have reached normal
operating temperature.
Regeneration of the filter is automatic and nor-
mally takes 10-20 minutes. It may take a little
longer at a low average speed. Fuel consump-
tion may increase slightly during regeneration.
Regeneration in cold weatherIf the car is frequently driven short distances in
cold weather then the engine does not reach
normal operating temperature. This means that
regeneration of the diesel particle filter does
not take place and the filter is not emptied.When the filter has become approximately
80% full of particles, a warning triangle on the
instrument panel illuminates, and the message
Soot filter full See manual is shown on the
instrument panel display.
Start regeneration of the filter by driving the car
until the engine reaches normal operating tem-
perature, preferably on a main road or motor-
way. The car should then be driven for approx-
imately 20 minutes more.
NOTE
A smaller reduction of engine power may be
noticed temporarily during regeneration.
When regeneration is complete the warning
text is cleared automatically.
Use the parking heater* in cold weather so that
the engine reaches normal operating tempera-
ture more quickly.
IMPORTANT
If the filter fills up with particles then it can
be difficult to start the engine and the filter
will be incapable of functioning. Then there
is a risk that the filter will have to be
replaced.
