Refuelling
156which conforms to European standard
EN 228 or German standard DIN 51626-1.
You could otherwise impair engine output
or damage the engine.
i If the recommended fuel is not available
and only as a temporary measure, you may
also use premium unleaded petrol,
95 RON/85 MON. This may reduce engine
performance and increase fuel consump-
tion. You must avoid driving at full throttle.
! In emergencies, and only when the rec-
ommended fuel is not available, you may
also use standard unleaded petrol,
91 RON/82.5 MON. However, using this
fuel results in considerably higher petrol
consumption and significantly reduced per-
formance. Avoid driving at full throttle, and
only drive in drive program C.
If no fuel other than regular petrol fuel
91 RON/82.5 MO Nor a lower grade is per-
manently available, you should have the
vehicle adapted to run on this fuel by the
local after-sales service. Diesel (EN 590, DIN 51628)
! Refuel using only Diesel which conforms
to European standard EN 590 or German
standard DIN 51628.
You could otherwise impair engine output
or damage the engine.
You will find further information about die-
sel under "Fuel" in the index.
! When refuelling vehicles with a diesel 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 a higher sulphur content
is available (e.g. 0.035 percent by weight),
the engine oil should be renewed at more
frequent intervals. More information about
intervals for changing the engine oil can be
obtained from any Mercedes-Benz Service
Centre.
! The use of fuels which do not meet the
requirements of EN 590 or German stand-
ard DIN 51628 can cause increased wear,
and damage the engine and 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 war-
ranty.
Low outside temperatures The flow properties of diesel may be insuffi-
cient at low ambient temperatures.
To prevent operating problems, diesel fuel
with improved cold flow qualities is available
during the winter months. Your vehicle must
be refuelled with this winter diesel at temper-
atures of -5 °C or below.
You can use this winter diesel at tempera-
tures down to about -20 °C without problems.Operation

In the event that the:
R engine oil brand
R grade (MB Sheet number)
R SAE classification (viscosity)
is not available, you can use another min-
eral or synthetic engine oil which has been
approved by Mercedes-Benz.
Mixing oils reduces the benefits of high-
grade engine oil.
! Do not use lubricant additives as they can
lead to increased wear and damage to
mechanical assemblies. The use of lubri- cant additives will result in a restriction of
your warranty.
! Engine oils for vehicles without a diesel
particle filter may also be used temporarily
in vehicles with a diesel particle filter if the
engine oil listed is not available. You must
then have an oil change carried out as soon
as possible.
30 Restriction: only SAE 0W-40 or SAE 5W-40 engine oils may be used. Technical data
