Do not mix such fuels with diesel fuel and
do not use any special additives. This can
otherwise lead to engine damage. This
does not include flow improver additives.
For further information, see "Flow improv-
ers".
! Vehicles with a diesel particle filter: in
countries outside the EU, only refuel with
low-sulphur Euro diesel with a sulphur con-
tent under 50 ppm; otherwise the emission
control system could be damaged.
Usually you will find information about the
fuel grade on the pump. If you cannot find the
label on the petrol pump, ask the filling sta-
tion staff.

Low outside temperatures
In winter months, diesel fuel with an improved
cold flow quality is available. In Europe, the
EN 590 standard defines various climate-
dependent temperature categories. Malfunc-
tions can be avoided by refuelling with diesel
fuel that corresponds to the climatic specifi-
cations outlined in EN 590. At unusually low
outside temperatures, it is possible that the
flow characteristics of the diesel fuel could be
insufficient. Accordingly, diesel fuel from
warmer areas may not be suitable for opera-
tion in colder climatic conditions.
i Further information on country-specific
fuel properties can be obtained from oil
companies, e.g. at filling stations.

Service products and capacities
Flow improvers
Flow improvers can be added to improve the
cold resistance of diesel fuel. The effective-
ness of flow improvers cannot be guaranteed
with all fuels.
Only use flow improvers tested and approved
by Mercedes-Benz. During use, please
observe the information on operation.
Correct dosage and thorough mixing are deci-
sive factors in ensuring improvement in low-
temperature resistance. Under certain cir-
cumstances, an excessive dosage may
actually decrease low-temperature resist-
ance and should therefore be avoided. Follow
the manufacturer's dosing instructions.
Mix the additive into the diesel in good time,
before the flow characteristics of the diesel
become insufficient. Otherwise, malfunctions
can only be rectified by heating the entire fuel
system, e.g. by parking in a heated garage.
More information about recommended flow
improvers can be obtained from any qualified
specialist workshop.
Notes on fuel consumption
H
Environmental note
CO (carbon dioxide) is the gas which scien-
2
tists believe to be principally responsible for
global warming (the greenhouse effect). Your
vehicle's CO emissions are directly related to
2
fuel consumption and therefore depend on:
efficient use of the fuel by the engine
R
driving style
R
other non-technical factors, such as envi-
R
ronmental influences, road conditions or
traffic flow
You can minimise your vehicle's CO
sions by driving carefully and having it serv-
iced regularly.
The vehicle will use more fuel than usual in
the following situations:
at very low outside temperatures
R
in urban traffic
