must not come into contact with
your skin, eyes or clothing.
R If you ge tAdBlue ®
in your eyes or on your
skin, rinse thoroughly without delay using
clear water.
R If AdBlue ®
has been swallowed, rinse your
mouth out immediately with plenty of clean
water, and drink plenty of water.
R Change immediately out of clothing conta-
minated with AdBlue ®
.
R If you notice allergic reactions, visit a doc-
tor immediately.
Keep AdBlue ®
away from children.
Have the AdBlue ®
tank refilled at a qualified
specialist workshop. However, you can also
top up the AdBlue ®
tank:
R with AdBlue ®
refill bottles
R with an AdBlue ®
refill canister
If the outside temperature is below Ò11 †, it
may be difficult to top up. If AdBlue ®
is frozen
and there is an active warning indicator, top-
ping up may not be possible. Park the vehicle
in a warm place, e.g. in a garage, until
AdBlue ®
has become liquid again. Topping up
is then possible again. Alternatively, have the
AdBlue ®
tank refilled at a qualified specialist
workshop.
Have the AdBlue ®
supply checked at a quali-
fied specialist workshop before the following
types of journeys:
R journeys abroad outside of Europe
R off-road driving
X If necessary, have AdBlue ®
topped up.
Before a longer stay outside of Europe, con-
sult a qualified specialist workshop.

refill canisters can be obtained at
many filling stations or at a Mercedes-Benz
Service Centre. AdBlue ®
refill canisters are
often sold with a filler hose. Afiller hose that
does not exactly fit the vehicle's AdBlue ®
tank offers no protection against overfilling. Refuelling

Mercedes-Benz offers a special disposable
hose with overfill protection. You can obtain
this from any Mercedes-Benz Service Centre.
AdBlue ®
is available in a variety of containers
and receptacles. Only use the disposable
hose with Mercedes-Benz AdBlue ®
refill can-
isters. X
Unscrew the cap from the opening on top
of AdBlue ®
refill canister :.
X Place disposable hose ;on the opening
of AdBlue ®
refill canister :and screw it
on clockwise until hand-tight.
i Disposable hose ;remains closed until
you fasten disposable hose ;to the
AdBlue ®
filler neck of the vehicle.
X Place disposable hose ;on the filler neck
of the vehicle and screw it on clockwise
until hand-tight. When you feel resistance,
disposable hose ;is sufficiently secured.
X Lift up and tip AdBlue ®
refill canister :.
i Filling stops when the AdBlue ®
tank is
completely filled. Do not fill the AdBlue ®
tank any further. AdBlue ®
refill canis-
ter :can be removed when it has been
only partially emptied.
X Turn disposable hose ;on the filler neck
of the vehicle anti-clockwise and remove it. X
Turn disposable hose ;on the opening of
AdBlue ®

AdBlue ®
refill bottle !
Screw on the AdBlue ®
refill bottle only
hand-tight. It may otherwise be destroyed. AdBlue
®
refill bottles can be obtained at many
filling stations or at aMercedes-BenzS ervice
Centre. Refill bottles without a threaded seal
offer no protection against overfilling.
AdBlue ®
may leak out as a result of overfilling.
Mercedes Benzo ffers special refill bottles
with a threaded cap. These are available at
any Mercedes-Benz Service Centre.

WARNING
Fuels are poisonous and hazardous to health.
There is a danger of injury.
Do no tswallow fuel or let it come into contact
with skin, eyes or clothing. Do not inhale fuel
vapours. Keep fuels out of the reach of chil-
dren.
If you or others come into contact with fuel,
observe the following:
R Wash the fuel off any affected areas of skin
with water and soap immediately.
R If you get fuel in your eyes, rinse them thor-
oughly with clean water immediately. Seek
immediate medical attention.
R If fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.
R Change any clothing that has come into
contac twith fuel immediately.

Fuel grade
!
Do not use diesel to refuel vehicles with a
petrol engine. Even asmall quantity of die-
sel will damage the fuel injection system.
! Only refuel using unleaded petrol with at
least 95 RON/85 MON that conforms to European standard EN 228 or E DIN
51626-1 or an equivalent specification.
Fuel with this specification may contain up
to 10 % ethanol.
! Do not use the following:
R E85 (petrol with 85 % ethanol)
R E100 (100 %ethanol)
R M15 (petrol with 15 % methanol)
R M85 (petrol with 85 % methanol)
R M100 (100 % methanol)
R Petrol with metallic additives
R Diesel
Do not mix these fuels with petrol, and do
not use any additives. This can otherwise
lead to engine damage. This does not
include cleaning additives for the removal
and prevention of residue build-up. Only
cleaning additives recommended by
Mercedes-Benzs hould be added to petrol,
see "Additives". You can obtain further
information from any Mercedes-Benz
Service Centre.
! Use a filter when adding fuel from a fuel
can. The fuel lines and/or the diesel injec-
tion system could otherwise be blocked by
particles from the fuel can.
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.
i E10 fuel contains up to 10% bioethanol.
Your vehicle is suitable for use with E10
fuel. You can refuel your vehicle using E10
fuel.
i As a temporary measure, if the recom-
mended fuel is not available, you may also
use unleaded petrol with an octane rating
of 91 RON/82.5 MON. This may reduce
engine performance and increase fuel con-
sumption. Avoid driving at full throttle.

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
