AdBlue ®
Important safety notes
Comply with the important safety notes for
service products when handling
AdBlue
® ( Y page 405).
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, to
mucous membranes and to the 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. Only fill the AdBlue
® tank in well-
ventilated areas.
Low outside temperatures
AdBlue ® freezes at a temperature of approx-
imately -11 †. The vehicle is delivered from
the factory equipped with an AdBlue
® pre-
heating system. Winter operation can thus be
guaranteed 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.

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
