Genera lnotes To function properly, BlueTE
Cexhaust gas after-
treatment must be operated with the reducing
agent AdBlue ®
.
When the supply of AdBlue ®
is almost used up,
the Refill AdBlue See Owner's Manual Refill AdBlue See Owner's Manual
message is shown in the multifunction display .A

Refill AdBlue No start in Xkm
message is shown in the multifunction display,
you can still drive the vehicle over the distance
shown. If AdBlue ®
is not topped up, you will
subsequently be unable to startt he engine.
When you see the warning message, it is rec-
ommended that you fill the AdBlue ®
reservoir
with 10 litres of AdBlue ®
.T his ensures that the
AdBlue ®
supply will last until the next regular
service due date.
Further information about BlueTEC exhaust gas
aftertreatmen tand about AdBlue ®
can
be obtained from any Mercedes-Benz Service
Centre.
i You can also have the AdBlue ®
tank refilled
at aq ualified specialist workshop.
If the outside temperature is lower than Ò11 †,
it may be difficult to top up. If AdBlue ®
is frozen
and there is an active warning indicator, topping up may not be possible. Park the vehicle in a
warm place, e.g. in agarage, until AdBlue ®
has
become liquid again. Topping up is then possible
again. Alternatively, have the AdBlue ®
tank refil-
led at aqualified specialist workshop.
Before driving your vehicle outside Europe, have the AdBlue ®
supply checked at aqualified spe-
cialist workshop.

is aw ater-soluble fluid for the exhaust
ga sa ftertreatment of diese lengines. It is:
R non-toxic
R colourless and odourless
R non-flammable If you open the AdBlue
®
tank ,small amounts of
ammonia vapourm ay be released.
Ammonia vapours have apungent odoura nd are
particularly irritating to the skin, mucous mem-
branes and eyes.Y ou may experience aburning
sensation in youre yes,nose and throat. You
may also experience coughing and watery eyes.
Do not inhalea ny ammonia vapours that may be
released. Fill the AdBlue ®
tank only in well-ven-
tilated areas.
Do not swallow AdBlue ®
or let it come into con-
tact with skin, eyes or clothing. Keep AdBlue ®
awayf rom children.
If you or others come into contact with AdBlue ®
,
observe the following:
R immediately rinse AdBlue ®
off yours kin with
soap and water.
R if AdBlue ®
comes into contact with youre yes,
immediately rinse them thoroughl ywith clean
water. Seek medica lattention immediately.
R if AdBlue ®
is swallowed, immediately rinse
yourm outh out thoroughly. Drink plenty of
water. Seek medica lattention immediately.
R change immediately out of clothing that has
come into contact with AdBlue ®
.
! Only use AdBlue ®
in accordance with
ISO 22241. Do not mix any additives with
AdBlue ®
,a nd do not dilute AdBlue ®
with
water. This may destroy the BlueTEC exhaust
gas aftertreatment system.
! In order to fill the AdBlue ®
tank, the vehicle
must be parked on alevel surface. The
AdBlue ®
tank can only be filledasi ntended
with the vehicle parked on alevel surface.
Fluctuations in capacity willt hus be avoided.
Filling avehicle standing on an uneven sur-
face is not permitted. There is adanger of
overfilling, which can cause damage to Blue-
TEC exhaust gas aftertreatment components.
! Surfaces which have come into contact with
AdBlue ®
whiler efilling shouldber insed
immediately with water, or remove AdBlue ®
with amoist cloth and cold water. If AdBlue ®
has already crystallised, use asponge and
cold water to clean the area.A dBlue®

crystallises after acertain amount of time and
soils the affected surfaces.

WARNING
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of pure diesel fuel.W hen the engine is running,
components in the exhaust system may over-
heatu nnoticed. There is arisk of fire.
Never refue lwith petrol. Never add petrol to
diesel fuel.
! When refuelling, only use diesel fuel that
conforms to the European standard EN 590 or is of equivalent quality .Fuel that does not
conform to EN 590 can leadtoi ncreased wear
as wellasd amage to the engine and 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 mix such fuels with diesel fuel and do
not use any special additives. Otherwise,
engine damage may occur.
! Vehiclesw
ith diesel particle filters: in
countries outside the EU, only use low sulphur
Euro diesel with asulphurc ontent of under
50 ppm. Otherwise, the emission control sys- tem could be damaged.
You will usually find information aboutt he fuel
quality on the pump. If you cannot find the label
on the petrol pump, ask the filling station staff.
Information on refuelling (Y page 109).
Low outside temperatures In winter months, diesel fuel with an improved
cold flow quality is available. In Europe, the
EN 590 standard defines various climate-
dependent temperature categories. Malfunc-
tions can be avoided by refuelling with diesel
fuel that corresponds to the climatic specifica-
tions outlined in EN 590. At unusually low out-
side temperatures, it is possible that the flow
characteristics of the diesel fuel could be insuf- ficient. Accordingly, diesel fuel from warmer
areas may not be suitablef or operation in colder
climatic conditions.
i Further information on country-specific fuel
properties and fuel types with low-tempera-
ture resistance can be obtained from oil com- panies, e.g. at filling stations. AdBlue

Engine oil
General notes When handling engin
eoil, observe the important
safety notes on service products (Y page 250).
The quality of the engine oil is decisive for the
function and service life of an engine. After
extensive tests, Mercedes-Benz approves
engine oils that correspond to the curren ttech-
nical standard.
Therefore, only Mercedes-Benz-approved
engine oils may be used in Mercedes-Benz
engines.
Further information on tested and approved
engine oils can be obtained from any Mercedes-
Benz Servic eCentre. Mercedes-Benz recom-
mends that you have the oil change carried out
at aq ualified specialist workshop. Mercedes-
Benz approval is indicated on the oil container
by the inscription „MB-Freigabe“ or „MB
Approval“ and the corresponding designation,
e.g. MB-Freigabeor MB Approval 229.51.
You can call up an overview of approved engine oils on the Internet at
http://bevo.mercedes-benz.com by entering
