You will generally find information about the
fuel grade on the filling pump. If there is no
identification on the filling pump, consult a
gas station attendant.
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 the engine's
performance and increase fuel consumption.
Avoid driving at full throttle and sudden accel-
eration. Never refuel using fuel with a lower
AKI/RON rating.

In some countries, the available gasoline
may not be sufficiently low in sulfur. This fuel
can temporarily produce unpleasant odors,
especially on short journeys. The odors are
reduced as soon as sulfur-free fuel (sulfur
content < 10 ppm) is used again for refueling.

Fuel additives
!
Operating the engine with subsequently
added fuel additives can cause engine dam-
age. Do not mix fuel additives with fuel. This
does not include additives for the removal and
prevention of deposits. Gasoline can only be
mixed with additives recommended by
Mercedes-Benz. Follow the instructions in the
product description. You can find further
information on recommended additives in any
Mercedes-Benz Commercial Van Center.
Mercedes-Benz recommends using brand-name
fuels with additives.
If you use fuels without these additives for a long
period of time, deposits can form. This primarily
forms on the inlet valve and in the combustion
chamber.
In some countries, the available fuel grade may
be inadequate. Residue could build up in the fuel
injection system as a result. In this case, in con-
sultation with a Mercedes-Benz Commercial
Van Center, the fuel should be mixed with the
cleaning additive recommended by Mercedes-
Benz. You must observe the notes and mixing
ratios indicated on the container.
Do not add other fuel additives to the fuel. This
results in unnecessary costs and can damage
the engine.
Information on fuel consumption
H
Environmental note
CO
2
(carbon dioxide) is the gas which scien-
tists believe to be principally responsible for
global warming (the greenhouse effect). Your
vehicle's CO
2
emissions are directly related to
fuel consumption and therefore depend on:
R
efficient use of the fuel by the engine
R
driving style
R
other non-technical factors, such as envi-
ronmental influences, road conditions or
traffic flow
You can minimize your vehicle's CO
2
emis-
sions by driving carefully and having it serv-
iced regularly.
Only for certain countries: the respective cur-
rent consumption and emission values of your
vehicle can be found in the COC papers (EC
CERTIFICATE OF CONFORMITY). These docu-
ments are supplied when the vehicle is deliv-
ered.
Consumption figures were found in the currently
valid respective version:
R
for vehicles up to and including the Euro 4
standard according to EU Directive
80/1268/EEC
R
for vehicles from the Euro 5 standard accord-
ing to regulation (EC) no. 715/2007
R
for vehicles from the Euro 6 standard accord-
ing to regulation (EC) no. 595/2009
Fuel consumption depends on:
R
the vehicle version
R
the style of driving
R
the operating conditions
R
the type or quality of the fuel used
The vehicle will use more fuel than usual in the
following situations:
R
at very low outside temperatures
R
in city traffic
R
during short journeys
R
on mountainous terrain
R
when towing a trailer
Observe the advice in the "Protection of the
environment" section to keep fuel consumption
low (
