i You can also have the AdBlue ®
tank refilled
at a qualified specialist workshop.
Before driving your vehicle outside Europe, have
the AdBlue ®
supply checked at a qualified spe-
cialist workshop.
Further information about BlueTEC exhaust gas
aftertreatment and about AdBlue ®
can
be obtained from any Mercedes-Benz Service
Centre.
Important safety notes AdBlue
®
is a water-soluble fluid for the exhaust
gas aftertreatment of diesel engines. It is:
R non-toxic
R colourless and odourless
R non-flammable
If you open the AdBlue ®
tank, small amounts of
ammonia vapour may be released.
Ammonia vapours have a pungent odour and are
particularly irritating to the skin, mucous mem-
branes and eyes. You may experience a burning sensation in your eyes, nose and throat. You
may also experience coughing and watery eyes.
Do not inhale any 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 your skin, eyes or clothing. Keep
AdBlue ®
away from children.
If you or others come into contact with AdBlue ®
,
observe the following:
R immediately rinse AdBlue ®
off your skin with
soap and water.
R if AdBlue ®
comes into contact with your eyes,
immediately rinse them thoroughly with clean water. Seek medical attention immediately.
R if AdBlue ®
is swallowed, immediately rinse
your mouth out thoroughly. Drink plenty of
water. Seek medical attention 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 ®
, and 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 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 avoided.
Filling a vehicle standing on an uneven sur-
face is not permitted. There is a danger of
overfilling, which can cause damage to Blue-
TEC exhaust gas aftertreatment components.
! 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 surfaces.
! AdBlue ®
is not a fuel additive and must not
be added to the fuel tank. If AdBlue ®
is added
to the fuel tank, this can lead to engine dam- age.
Have the AdBlue ®
tank refilled at a qualified
specialist workshop. However, you can also top
up the AdBlue ®
tank:
R at a filling station with an AdBlue ®
filling pump
R with AdBlue ®
refill bottles
R with an AdBlue ®
refill canister Refuelling
157Driving and parking Z
When the pump nozzle switches off automati-
cally during filling at a filling pump, the AdBlue ®
tank has been completely filled. Do not fill the
AdBlue ®
tank any further. AdBlue ®
may leak
out.
To avoid transporting already opened refill con-
tainers in the vehicle, completely empty refill
bottles or canisters when filling the AdBlue ®
tank, if possible.

AdBlue ®
refill canisters are available at many
filling stations or at a qualified specialist work-
shop. AdBlue ®
refill canisters are often sold with
a filler hose. A filler hose that does not exactly fit
the vehicle's AdBlue ®
tank offers no overfill pro-
tection. AdBlue ®
may leak out as a result of
overfilling. Mercedes-Benz offers a special dis-
posable hose with overfill protection. You can
obtain this from any Mercedes-Benz Service
Centre. AdBlue ®
is available in a variety of con-
tainers and receptacles. Use the disposable
hose only with the Mercedes-Benz AdBlue ®

no overfill protection. AdBlue ®
may leak out as a
result of overfilling. Mercedes-Benz offers spe-
cial refill bottles with a threaded cap. These are
available at any Mercedes-Benz Service Centre. Parking
Important safety notes
G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system or exhaust
gas flow. There is a risk of fire.
Park the vehicle so that no flammable mate-
rial can come into contact with hot vehicle
components. In particular, do not park on dry grassland or harvested grain fields. G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position Por shift manual transmission into
neutral
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle.
! Always secure the vehicle correctly against
rolling away. Otherwise, the vehicle or its driv-
etrain could be damaged. Parking
