! Refuel using only unleaded, sulphur-free
premium grade petrol with aminimum
octan enumber of 95 RON/85 MON con-
formin gtoEuropean standard EN 228.
Otherwise, you could impair engine output
or damage the engine. i
Asatemporary measure, only when the
recommended fuel is not available, you
may also use regular unleaded petrol,
91 RON/82. 5MON. This may reduce
engine performance and increase fuel con-
sumption. Avoid driving at full throttle.
In some countries, the fuel grade available
may not be adequate and could cause cok-
ing around the inlet valve. In such cases,
and in consultation with aMercedes-Benz
Servic eCentre, the petrol may be mixed
with the additive recommended by
Mercedes-Benz (part no.
A000989254510). You must observe the
notes and mixing ratios specified on the
container.

Risk of fire
Do not use petrol to refuel vehicles with adie-
sel engine. Do not mix diesel with petrol. This
would result in damage to the fuel system and
engine, which could lead to avehicle fire.
! Refuel using only diesel which conforms
to European standard EN 590 or German
standard DIN 51628. Otherwise, you could
impair engine output or damage the engine.
! When refuelling vehicles with adiesel par-
ticulate filter in countries outside the EU,
only low-sulphur Euro diesel with less than
0.005 percent sulphur content by weight
(50 ppm) should be used.
! In countries in which diesel with ahigher
sulphur content is available, the engine oil
should be renewed at more frequent inter-
vals. More information about intervals for
changin gthe engine oil can be obtained
from any Mercedes-Benz Servic eCentre.

standard DIN 51628 can lead to increased
wear, engine damage and damage to the
exhaust system.
Do not use the following:
R
marine diesel
R heating oil
R bio-diesel
R vegetable oil
R petrol
R paraffin
R kerosene
Do not add such fuels to diesel fuel and do
not use any special additives (exception:
flow improvers –see "Low outside temper-
atures").
Damage caused by the use of unapproved
fuels or additives is not covered by the
implied warranty.
Further information on "Fuel" (Y page 287).
Low outside temperatures The flow properties of diesel may be inade-
quate at low ambient temperatures.
Diesel fuel with improved cold flow qualities
is available during the winter months. In
Europe, the different climate-dependant cold
categories are defined in standard EN 590.
Refuelling with diesel fuel which complies
with the climatic specifications of standard
EN 590 can help to prevent operating prob-
lems. If the ambient temperature is unusually
low or if you use fuel that has not been adap-
ted to the climatic specifications (e.g. diesel
fuel from the Mediterranean area), the flow
properties of the fuel may be inadequate.
Flow improver
Flow improvers can be added to improve the
cold resistance of diesel fuel. The effective-
ness of aflow improver is not guaranteed with
every fuel.
Correct dosage and thorough mixing are deci-
sive factors in ensuring improvement in low- temperature resistance. Under certain cir-
cumstances, an excessive dosage may
actually decrease low-temperature resist-
ance and should therefore be avoided (follow
the manufacturer's dosing instructions).
Mix the additive with the diesel in good time,
before the flow properties of the diesel
become inadequate. Otherwise, malfunctions
can only be rectified by heating the entire fuel
system, e.g. by parking the vehicle in
aheated
garage.
Observe the information provided by the man-
ufacturer when using aflow improver. Only
use flow improvers that have been tested and
approved by Mercedes-Benz.Y ou can obtain
further information from any Mercedes-Benz
Service Centre. Enginec

Risk of accident
Do not pull the release lever while the vehicle

Active bonnet( pedestrian protection) The active bonnet can reduce the risk of injury
to pedestrians in certain accident situations.
Raising the bonnet increases the clearance to
hard components, such as the engine. Fur-

Depending on driving style, the vehicle con-
sumes up to 0.8 loil per 1,000 km. The oil
consumption may be highert han this when
the vehicle is new or if you frequently drive at
high engine speeds.
Checking the engine oil level Before checking the engine oil level the fol-
lowing conditions for the vehicle shouldbe
met:
R
the vehicle shouldbep arked on level
ground.
R the engine shouldbes witched off for at
least five minutes if the engine is at normal
operating temperature.
R the engine shouldbes witched off for at
least 30 minutes if the engine is not at
operating temperature (i.e. if you only start
the engine briefly).
Depending on the engine, the oil dipstick may
be installed at adifferent location. E3

tube.
X Wipe off oil dipstick 0046.
X Insert oil dipstick 0046into the oil dipstick

mark 0047.
X Top up the oil if necessary.

Environmental note
When topping up the oil, take care not to spill
any. Oil must not be allowed to escape into
the soil or waterways. You would otherwis ebe
damaging the environment. Cap (example)
