The Mercedes-Benz implied warranty does not
cover damage if:
it is directly or indirectly caused by the use

of fatty acid methyl ester which does not
comply with DIN EN 14214.
the specifications in accordance with Sheet
R
135 of the Mercedes-Benz Specifications for
Service Products for operation with fatty
acid methyl ester are not observed.
malfunctions or consequential damage (e.g.
R
paintwork damage) are caused by handling
fatty acid methyl ester or running the vehi-
cle on fuels of this type.
Low outside temperatures
Fatty acid methyl ester compliant with
DIN EN 14214 can be used reliably at outside
temperatures down to Ò20 †.

AdBlue
Important safety notes
®
AdBlue is a water-soluble fluid for the
exhaust gas aftertreatment of diesel engines.
It is:
non-toxic
R
colourless and odourless
R
non-flammable
R
When opening the AdBlue
amounts of ammonia vapours may escape.
Ammonia vapours have a pungent smell and
are particularly irritable to skin, mucous mem-
branes and eyes. You may experience a burn-
ing sensation in your eyes, nose and throat. A
dry cough and watering eyes are also possible.
Avoid inhaling ammonia vapours. Only fill the
®
AdBlue tank in well-ventilated areas.
®
Avoid letting AdBlue
skin, eyes or clothing, and swallowing it. Keep
®
AdBlue out of the reach of children.
If you or another person come into contact
®
with AdBlue , observe the following:
immediately rinse AdBlue
R
soap and water
®
if AdBlue comes into contact with your
R
eyes, immediately rinse them thoroughly
with clean water. Consult a doctor without
delay.

®
! Only use AdBlue /DEF in accordance with
DIN 70070/ISO 22241. Do not use any
additives.
®
If AdBlue /DEF comes into contact with
painted or aluminium surfaces when filling
the tank, rinse the affected area immedi-
ately with plenty of water.
It may be against regulations, or in some coun-
tries punishable, to operate a vehicle which
®
does not use AdBlue
®
AdBlue that does not meet the requirements
of these Operating Instructions.
High outside temperatures
The chemical composition of AdBlue
break down if it heats up to over 50 † over a
long period of time (e.g. as a result of direct
sunlight on the tank). This creates ammonia
vapour.
Low outside temperatures
®
AdBlue freezes at a temperature of approx-
imately −11 †. AdBlue
heated using the vehicle's coolant system.
Winter operation is also ensured for tempera-
tures below −11 †.
At low temperatures, AdBlue
form on the coiled hose between the engine
and the silencer. This crystallisation does not
pose a risk to the correct operation of Blue-
®
Tec exhaust gas aftertreatment. The AdBlue
crystals can be removed with a sponge and
clean water if necessary.

are not suited to storing AdBlue
