AdBlue
®
Important notes on use To function properly, BlueTEC exhaust gas
aftertreatment 1
mus tbe operated with the
reducing agent AdBlue ®
.
When the supply of AdBlue ®
is almost used
up, the Refill AdBlue See Owner's Man‐
ual message is shown in the multifunction
display. Awarning tone also sounds.
If the Refill AdBlue No start in: .. km message is shown in the multifunction dis-
play, you can still driv ethe vehicle over the
distance shown. Awarning tone also sounds.
If the AdBlue ®
is no ttopped up, you will sub-
sequently be unable to start the engine.
After receiving the warning message, it is
preferable to fill the AdBlue ®
tank with
10 litres of AdBlue ®
.Int his way, you can
ensure that the AdBlue ®
supply lasts until the
next regular service date.
Further information about BlueTEC exhaust
gas aftertreatment and about AdBlue ®
can
be obtained from any Mercedes-Ben zService
Centre.
Topping up AdBlue ®!
Only use AdBlue ®
in accordance with
ISO 22241. Do not mix any additives with
AdBlue ®
, and do not dilute AdBlue ®
with
water. This may destroy the BlueTEC
exhaust gas aftertreatmen tsystem.
! In order to fill the AdBlue ®
tank, the vehi-
cle mus tbe parked on a level surface. The
AdBlue ®
tank can only be filled as intended
with the vehicle parked on a level surface.
Fluctuations in capacity will thus be avoi-
ded. Filling a vehicle standing on an uneven
surface is not permitted. There is a danger
of overfilling, which can cause damage to
BlueTEC exhaust gas aftertreatmen tcom-
ponents. !
Do not fill the AdBlue ®
container with a
pump nozzle.
! If there are steep gradients while driving
off-road, a sufficient filling level in the
AdBlue ®
tank must be ensured. Make sure
for this reason that there is a minimum fill
level of ten litres before driving off-road.
! Surfaces which have come into contact
with AdBlue ®
while refilling should be
rinsed immediately with water, or remove
AdBlue ®
with a moist cloth and cold water.
If AdBlue ®
has already crystallised, use a
sponge and cold water to clean the area.
AdBlue ®
residue crystallises after a certain
amount of time and soils the affected sur-
faces.
! AdBlue ®
is not a fuel additive and must
not be added to the fuel tank.IfA dBlue®
is
added to the fuel tank, this can lead to
engine damage.
If you open the AdBlue ®
tank cap, small
amounts of ammonia vapour may be
released.
Ammonia vapours have a pungen todour and
are particularly irritating to:
R skin
R mucous membranes
R eyes
You may experience a burning sensation in
your eyes, nose and throat, as well as cough-
ing and watering of the eyes.
Do not inhale any ammonia vapours that may
be released. Fill the AdBlue ®
tank only in well-
ventilated areas.

WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, naked flames, creating
sparks and smoking. Switch off the engine Service products and capacities

WARNING
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of
pure diesel fuel .When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is arisk of fire.
Never refuel with petrol. Never add petrol to
diesel fuel.
! When refuelling, only use diesel fuel that
conforms to the European standard EN 590
or is of equivalen tquality. Fuel that does
not conform to EN 590 can lead to
increased wear as well as damage to the
engine and exhaust system.
! Do no tuse 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. This can
otherwise lead to engine damage.T his
does not include flow improver additives.
For further information, see "Flow improv-
ers".
! Vehicles with adiesel particle filter: in
countries outside the EU, only refuel with
low-sulphur Euro diesel with a sulphur con-
ten tunde r50p pm; otherwise the emission
control system could be damaged.
! Vehicles without adiesel particle fil-
ter: in countries where only diesel fuel with
a high sulphur conten tis available, you will
need to carry out your vehicle's oil change
at shorter intervals. More information
aboutt he interval for oil change can be
obtained from any qualified specialist
workshop.
Usually you will find information about the
fuel grade on the pump. If you cannot find the label on the petrol pump, ask the filling sta-
tion staff.
Information on refuelling (Y
page 157).
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 specifi-
cations outlined in EN 590. At unusually low
outside temperatures, it is possible that the
flow characteristics of the diesel fuel could be
insufficient .Accordingly, diesel fuel from
warmer areas may not be suitable for opera-
tion in colder climati cconditions.
i Further information on country-specific
fuel properties can be obtained from oil
companies, e.g. at filling stations.
Flow improvers
Flow improvers can be added to improve the
cold resistance of diesel fuel. The effective-
ness of flow improvers cannot be guaranteed
with all fuels.
Only use flow improvers tested and approved
by Mercedes-Benz. During use, please
observe the information on operation.
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 into the diesel in good time,
before the flow characteristics of the diesel
become insufficient. Otherwise, malfunctions
can only be rectified by heating the entire fuel
system, e.g. by parking in a heated garage.
More information about recommended flow
improvers can be obtained from any qualified
specialist workshop. 344

AdBlue
®
General notes AdBlue
®
is a non-flammable, non-toxic, col-
ourless, odourless and water-soluble fluid.
High outside temperatures If you open the AdBlue
®
tank cap, small
amounts of ammonia vapour may be
released.
Ammonia vapours have a pungen todour and
are particularly irritating to:
R skin
R mucous membranes
R eyes
You may experience a burning sensation in
your eyes, nose and throat, as well as cough-
ing and watering of the eyes.
Do not inhale any ammonia vapours that may
be released. Fill the AdBlue ®
tank only in well-
ventilated areas.
Low outside temperatures AdBlue
®
freezes at a temperature of approx-
imately -11 †. The vehicle is equipped with
an AdBlue ®
preheating system at the factory.
Winter operation can therefore be guaran-
teed even at temperatures below -11 †.
Additives !
Only use AdBlue ®
in accordance with ISO
22241. Do not use additives with AdBlue ®
and do not dilute AdBlue ®
with water. This
may destroy the BlueTEC exhaust gas after-
treatment system.
Purity !
Impurities in AdBlue ®
(e.g. due to other
service products, cleaning agents or dust)
lead to:
R increased emission values
R damage to the catalytic converter R
engine damage
R malfunctions in the BlueTEC ®
exhaust
gas aftertreatment system
Assuring the purity of AdBlue ®
is particularly
important with respec ttoavoiding malfunc-
tions in the BlueTEC exhaust gas aftertreat-
ment system.
If AdBlue ®
is pumped out of the AdBlue ®
tank,
e.g. during repair work, do not use this fluid
to refill the tank. The purity of the fluid can no
longer be guaranteed.

Engine oil
General notes 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 current
technical 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 Service Centre. Mercedes-
Ben
zrecommends that you have the oil
change carried out at a qualified specialist
workshop. Mercedes-Benza pproval is indica-
ted on the oil container by the inscription "MB
Approval" and the corresponding designa-
tion, e.g. MB Approval 229.51.
You can call up an overview of approved
engine oils on the Internet at
http://bevo.mercedes-benz.com by enter-
ing the designation, e.g. 229.5.

Additives
!
Do not use any additives with the engine
oil. This could damage the engine.
Engine oil viscosity Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity
rating, it flows slowly; the lower the viscosity,
the faster it flows.
Engine oil selection is based on the respective
outside temperatures and in accordance with
the SAEc lassification (viscosity). The table
shows you which SA Eclassifications are to be
used. The low-temperature properties of
engine oils can be significantly impaired dur-
ing operation due to, for example, ageing or
soot and fuel accretion. It is therefore
strongly recommended to observe regular oil
changes using an approved engine oil with the
appropriate SA Eclassification. Brake fluid
