General notes
The filler neck is located in the rear right-side panel.
The fuel tank cap turns freely to prevent it’s opening without a key.
Open the cover, hold the cap with one hand and next introduce the
key in the lock and turn it 180° to the left. At this moment the cap
should unscrew in a counter-clockwise direction.
To close, screw the cap to the right until you hear a "click". Turn the
key without releasing the cap clockwise 180°. Remove the key and
close the cover.
The tank holds about 45 liters.

As soon as the automatic nozzle, correctly operated, disconnects for the
first time, the tank is full. Do not continue filling since the expansion space
would be occupied. If it heats up the fuel could overflow.
After filling the tank, screw cap and close tank flap until it engages.
The cap is tied to an anti-loss cord.
NNoottee
Any fuel spillage should be wiped off the paint finish immediately, as the
paint could otherwise be damaged, especially if it is RME (“biodiesel”) fuel.
CCaauuttiioonn
On vehicles with a catalytic converter, never drive until the fuel tank is
completely empty. The irregular fuel supply can cause misfiring. This allows
unburnt fuel into the exhaust system, which can cause overheating and
damage to the catalyst.

In the chapter “Technical Data” and on the inside of the tank flap
you will find information on the correct octane rating for your
engine.
General notes
•
Unleaded petrol must comply with DIN EN
1)
228 and leaded
petrol with
DIN 51 600.
•
If, in an emergency, the octane rating of the available petrol is
lower than that required by the engine, only drive with medium
engine speeds and low engine loading.

Fill tank with
petrol of the correct octane rating as soon as possible.
•
Fuel with a higher octane rating than that required by the engine
can be used without limitation. There are, however, no advantages
regarding output and consumption.

Even one tankful of leaded petrol will detract from the efficiency of the
catalytic converter.

Petrol additives
The quality of the fuel has a decisive influence upon the running
behavior, performance and service life of the engine. The additives
which are mixed into the petrol are of particular significance. Itis

Properties of RME
•
RME is chemically produced from vegetable oil (predominantly
rapeseed oil) in a process whereby the oil is mixed with methanol
and converted, via a catalyst, into RME.
•
RME is almost totally sulfur free. The combustion of RME thus
emits practically no sulfur dioxide (SO
2
).
•
Exhaust gas contains less
– carbon monoxide
– hydrocarbons
– particles (i.e. soot)
than with conventional diesel fuel.
All emission values are lower than legal requirements.
•
RME fuel is biodegradable.
•
Performance may be slightly lower.
•
Fuel consumption may be slightly higher.
•
RME can be used in temperatures down to approximately –10 °C.
•
Diesel fuel must be added at ambient temperatures of less than
–10 °C to prevent deterioration to the biodiesel. The mixing ratio
of diesel to biodiesel must be approximately 50:50.

•
During the summer months, RME may be mixed with diesel at
any ratio.
Driving in winter
When using summer Diesel trouble may be experienced at
temperatures below
0 °C because the fuel thickens due to wax separation.
For this reason winter Diesel which is more resistant to cold is sold
during the winter in some countries, and this works correctly down
to between –15 °C and –22 °C approximately, depending on the
brand of fuel used.
The biodiesel available in countries with different climactic
conditions usually has different temperature characteristics.
Technical Service Centres or service stations in each country can
inform you of the specific characteristics of the respective diesel.
Filter preheating
The vehicle is fitted with a filter preheater. This will ensure that the
fuel system will remain operational down to about –25 °C,
provided that winter Diesel which is cold resistant down to –15 °C
is used.
If, at temperatures below –25 °C the fuel is waxed to such an
extent that the engine will not start it is sufficient to place the
vehicle in a warm enclosure for a while.
