Approx.
2.4 US gal (9.0 l) Gasoline
Fuel grade
!
Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the
ignition if you accidentally refuel with the
wrong fuel. Otherwise, the fuel will enter
the fuel system. Even small amounts of the
wrong fuel could result in damage to the
fuel system and the engine. Notify a
qualified specialist workshop and have the
fuel tank and fuel lines drained completely.
! Only refuel using unleaded gasoline with
a minimum octane rating of 91.
! Only use the fuel recommended.
Operating the vehicle with other fuels can
lead to engine failure.
! Do not use the following:
R E85 (gasoline with 85% ethanol)
R E100 (100% ethanol)
R M15 (gasoline with 15% methanol)
R M30 (gasoline with 30% methanol)
R M85 (gasoline with 85% methanol)
R M100 (100% methanol)
R Gasoline with metalliferous additives
R Diesel
Do not mix such fuels with the fuel
recommended for your vehicle. Do not use
additives. This can otherwise lead to engine
damage. This does not include cleaning
additives for the removal and prevention of
residue build-up. gasoline may only be
mixed with cleaning additives
recommended by Mercedes-Benz; see
"Additives". You can obtain further
information from any authorized Mercedes-
Benz Center. !
To ensure the longevity and full
performance of the engine, only premium-
grade unleaded gasoline must be used.
If standard premium-grade unleaded
gasoline is unavailable and unleaded
gasoline of a lower grade is used for
refueling, observe the following
precautions:
R only fill the fuel tank to half full with
regular unleaded gasoline and fill the rest
with premium-grade unleaded gasoline
as soon as possible.
R do not drive at the maximum speed.
R avoid sudden acceleration and engine
speeds above 3000 rpm.
R never refuel using fuel with an octane
number lower than 87. Otherwise,
engine failure could occur.
Using mixtures of methanol and ethanol is not
permitted. E10 fuel or E15 fuel (unleaded
gasoline with 10% or 15% ethanol) can be
used.
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
assistance.

qualified specialist workshop or on the
Internet at http://www.mbusa.com (USA

added later can lead to engine failure. Do
not mix fuel additives with fuel. This does
not include additives for the removal and
prevention of residue buildup. gasoline
must only be mixed with additives
