i Vehicles with a diesel engine:
If you have run the tank completely dry, it
will be necessary to bleed the fuel system
( Y page 289). Petrol (EN 228)
! Refuel using only unleaded premium
grade petrol with a minimum octane num-
ber of 95 RON/85 MON conforming to
European standard EN 228 .
You could otherwise impair engine output
or damage the engine.
You will find further information about pet-
rol under "Technical data" in the index .
i As a temporary measure, only when the
recommended fuel is not available, yo u
may also use regular unleaded petrol,
91 RON/82.5 MON. This may reduce per-
formance and increase petrol consump-
tion. Avoid driving at full throttle.
In some countries, the available petrol qual-
ity may not be sufficient and could caus e
coking around the inlet valve. In thes e
cases, and in consultation with a
Mercedes-Benz Service Centre, the petrol
may be mixed with the additive recommen-
ded by Mercedes-Benz (part no.
A000989254510). You must observe the
notes and mixing ratios given on the con -
tainer. Diesel (EN 590)
! Only use diesel that complies with the
EN 590 European standard.
You could otherwise impair engine outpu t
or damage the engine.
You will find further information about die-
sel under "Technical data" in the index.
! When refuelling vehicles with a diesel par-
ticle filter in countries outside the EU, only
low-sulphur Euro diesel with less than
0.005 percent sulphur content by weight
should be used. In countries in which diesel
with a higher sulphur content is available
(e.g. 0.035 percent by weight), the engine
oil should be renewed at more frequent
intervals. More information about intervals
for changing the engine oil can be obtained
from any Mercedes-Benz Service Centre.
! Using fuel that does not comply with EN
590 can increase wear and damage the
engine and the exhaust system. Do not use
the following:
R Marine diesel
R Heating oil
R Bio-diesel Operation

In the unusual event that the:
R engine oil brand
R grade (MB sheet number)
R SAE classification (viscosity )
corresponding to the oil used in your engine
is not available, you can use another min-
eral or synthetic engine oil approved by
Mercedes-Benz. Mixing oils reduces the advantages of
high–grade engine oil
.
! Do not use lubricant additives, since they
lead to increased wear and damage to the
mechanical assemblies. The use of lubri-
cant additives will result in a restriction of
your warranty. !
Engine oils for vehicles without a diese l
particle filter may also be used temporarily
in vehicles with a diesel particle filter if the
engine oil listed is not available. You must
then have an oil change carried out as soon
as possible.
