Do not use the following:
R marine diesel
R heating oil
R bio-diesel
R vegetable oil
R gasoline
R paraffin
R kerosene
Do not mix such fuels with diesel fuel and
do not use any special additives. This can
otherwise lead to engine damage.
! Vehicles with diesel particle filters:
in
countries outside the EU, only use low sul- fur Euro diesel with a sulfur content of
under 50 ppm. Otherwise, the emission
control system could be damaged.
! Vehicles without a diesel particle fil-
ter: in countries where only diesel fuel with
a high sulfur content is available, you will
need to carry out your vehicle's oil change
at shorter intervals. Further information on
oil change intervals can be obtained at a
qualified specialist workshop.
You will usually find information about the fuel
grade on the pump. If you cannot find the
label on the pump, ask the staff for assis-
tance.
Information on refueling (Y page 186).
Bio-diesel – FAME (fatty acid methyl ester) Mercedes-Benz USA approves the use of bio-diesel B5 for all BlueTEC diesel engines. The
concentration of bio-diesel in the ULSD may
not exceed 5% by volume.
Pure bio-diesel and diesel fuel with a higher
percentage of bio-diesel, such as B20, can
damage the engine and the fuel system. For
this reason, they are not approved.
For more information, consult the gas station
staff. The bio-diesel B5 label on the gasoline
pump must clearly state that the standard for ULSD has been fulfilled. If the label is not
clear, do not refuel the vehicle. Do not refuel your vehicle with fuels unless
they have been approved by Mercedes-Benz.

Low outside temperatures
i Diesel fuel with improved cold flow prop-
erties is available during the winter months.
Further information about fuel properties
can be obtained from oil companies, e.g. at gas stations. DEF
Important safety notes Comply with the important safety notes for
service products when handling DEF
(Y
page 447).
DEF is a water-soluble fluid for the exhaust
gas aftertreatment of diesel engines. It is:
R not poisonous
R colorless and odorless
R not flammable
When you open the DEF container, small
amounts of ammonia vapor may be released. Ammonia vapors have a pungent odor and are
particularly irritating to the skin, to mucous
membranes and to the eyes. You may expe-
rience a burning sensation in your eyes, nose and throat. Coughing and watering of the
eyes are possible.
Do not inhale ammonia vapors. Fill the DEF
tank only in well-ventilated areas.
Low outside temperatures DEF freezes at a temperature of approx-
imately 12 ‡(-11 †). The vehicle is delivered
from the factory equipped with a DEF pre-
heating system. Winter operation can thus be
guaranteed even at temperatures below 12 ‡
(-11 †). 450
