refuelusing only low-sulfurdiesel fuel with a
sulfur content less than 50 ppm. Otherwise,
the emission control system could be dam-
aged.
Compatibility labels for all vehicles with adiesel
engine
For diesel engines, you willfind the compatibil-
ity labels on the tensioning strap of the fuel
tank and on the fuel pump or on the fuel pump
nozzle of the filling station.
R
B7: for diesel fuel with amaximumof7%
bio-diesel (fatty acid methyl ester) by vol-
ume
R
XTL: for paraffinic diesel fuel in accordance
with EN 15940
Notes on low outside temperatures
Refuel yourvehicleatthe beginning of the win-
ter until the tank is as full as possible with win-
ter diesel.
Before switching to winter diesel, the fuel tank
must be as empty as possible. Keep the fuel
level low when refueling the vehiclewith win-
ter diesel for the first time, e.g. reserve level.
The next time you refuelthe vehicle, the fuel
tank may be filled up to anormal level again.

Important safety notes
G
WARNING
Fuel is highlyflammable. Improperhandling
of fuel creates arisk of fire and explosion.
Avoid fire, open flames, smoking and creat-
ing sparks under all circumstances. Switch
off the engine and, if applicable, the auxiliary
heating before refueling.
!
Filter the fuel before transferring it to the
vehicleifyou are refueling the vehiclefrom
barrels or containers.
This willprevent malfunctions in the fuel
system due to contaminated fuel.
!
Only refuelusing commercially available,
sulfur-free diesel fuel that conforms to the
European standard EN 590 as of 2010, et
seq. (max. 0.001% sulfur by weight).
The following fuel types are not permitted:
R
sulfurousfuel with asulfur content
greater than 0.001% by weight
R
marine diesel fuel
R
aviation turbine fuel
R
heating oils
R
FAME fatty acid methyl ester (bio-diesel
fuel)byvolume
These fuel types causeirreversibledamage
to the engine and exhaust gas aftertreat-
ment, as wellasalsosignificantly reducing
the expected service life.
!
Ahigh fuel sulfur content accelerates the
aging process of the engine oil and can
damage the engine and exhaust system.
Fuel grade
Before delivery, the fuel sulfur content is set to
<0.001% sulfur by volume (10ppm).
Certain countrieshave diesel fuel with varying
sulfur content. Dieselfuel with low sulfur con-
tent is sold in certaincountriesunderthe
name "Euro diesel".
Information regarding the current country-spe-
cific sulfur content of fuel can be obtained
from any Freightliner service center or found
on Sheet No. 136.2. of the Mercedes-Benz
Specification for Service Products.

WARNING
If you heatfuel system components, e.g.
with ahot-airgun or open flame, these com-
ponents couldbedamaged. This can cause
fuel to escapeand ignite.Depending on the
type of damage, fuel may also not escape
until the engine is running. There is arisk of
fire and explosion.
