! Only use the fuel recommended. Operating
the vehicle with other fuels can lead to dam-
age to the fuel system, engine and exhaust
system.
! Do not use the following: R
Gasoline with more than 10% ethanol R
E100 (1 00% ethanol)R
Gasoline with methanol R
M100 (1 00% methanol)R
Gasoline with metalliferous additives R
Diesel
Do not mix such fuels with the fuel recom-
mended for your vehicle.
! To ensure the longevity and full perform-
ance of the engine, only premium-grade
unleaded gasoline must be used.
If standard unleaded gasoline is unavailable
and you have to refuel with unleaded gasoline
of a lower grade, observe the following pre-
cautions: R
Only fill the fuel tank to half full with regular
unleaded gasoline and fill the rest with pre-
mium-grade unleaded gasoline as soon as
possible. R
Do not drive at the maximum speed. R
Avoid sudden acceleration and engine
speeds over 3,000 rpm.
You will usually find information about the fuel
quality on the pump. If you cannot find the label
on the fuel pump, ask the gas station staff.
i For further information, consult a qualified
specialist workshop or visit
http://www.mbusa.com (USA only).
As a temporary measure, if the recommended
fuel is not available, you may also use regular
unleaded gasoline with an octane rating of
87 AKI/91 RON. This may reduce engine per-
formance and increase fuel consumption. Avoid
driving at full throttle and sudden acceleration.
Never refuel using gasoline with a lower AKI.
Information on refueling ( Y
page 149).
Additives
! Operating the engine with fuel additives
added later can lead to engine failure. Do not
mi x fuel additives with fuel. This does not
include additives for the removal and preven-
tion of residue buildup. gasoline must only be
mixed with additives recommended by Mercedes-Benz. Comply with the instructions
for use on the product label. More information
about recommended additives can be
obtained from any authorized Mercedes-Benz
Center.
Mercedes-Benz recommends that you use bran-
ded fuels that have additives.
The fuel quality available in some countries may
not be sufficient. Residue could build up in the
fuel injection system as a result. In such cases,
and in consultation with an authorized
Mercedes-Benz Center, the fuel may be mixed
with the cleaning additive recommended by
Mercedes-Benz. You must observe the notes
and mixing ratios specified on the container.
Diesel Fuel grade
G WARNING
If you mix diesel fuel with gasoline, the flash
point is lower than that of pure diesel fuel.
When the engine is running, exhaust system
components could overheat without being
noticed. There is a risk of fire.
Never refuel with gasoline. Never mix gasoline
with diesel fuel.
! Refuel only using diesel fuel that conforms
to European standard EN 590 or an equivalent
specification. Fuel that does not conform to
EN 590 can lead to increased wear and dam-
age the engine and exhaust system.
! 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. Otherwise,
engine damage may occur.
! In countries outside the EU, only use low-
sulfur Euro diesel with a sulfur content of
under 50 ppm. Otherwise, the emission con-
trol system could be damaged.366

Technical data

You will usually find information about the fuel
quality on the pump. If you cannot find the label
on the fuel pump, ask the gas station staff.
Information on refueling ( Y
page 149).
Low outside temperatures
i Diesel fuel with improved cold flow proper-
ties 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 ser-
vice products when handling DEF ( Y
page 364).
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 experi-
ence 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 approximately
-11 †. The vehicle is delivered from the factory
equipped with a DEF preheating system. Winter
operation can thus be guaranteed even at tem-
peratures below -11 †.
Additives
! Only use DEF in accordance with ISO
22241. Do not use additives with DEF and do
not dilute DEF with water. This may destroy
the BlueTEC exhaust gas aftertreatment sys-
tem. Purity
! Impurities in DEF (e.g. due to other service
products, cleaning agents or dust) lead to: R
increased emission values R
damage to the catalytic converter R
engine damage R
malfunctions in the BlueTEC exhaust gas
aftertreatment system
Assuring the purity of DEF is particularly impor-
tant with respect to avoiding malfunctions in the
BlueTEC exhaust gas aftertreatment system.
If DEF is pumped out of the DEF tank, e.g. during
repair work, it must not be returned to the tank.
The purity of the fluid can no longer be guaran-
teed.

Engine oil
General notes
! Do not use engine oil or an oil filter with
specifications deviating from those expressly
required for the prescribed service intervals.
Do not change the engine oil or oil filter in
order to set replacement intervals longer than
those prescribed. This could otherwise cause
damage to the engine or exhaust gas after-
treatment.
Follow the instructions on the service interval
display for changing the engine oil. This couldService products and filling capacities 367
