Important safety notes
Comply with the important safety notes for ser-
vice products when handling AdBlue
®
(
Y
page 337).
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 experi-
ence 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-ven-
tilated areas.
Low outside temperatures
AdBlue
®
freezes at a temperature of approx-
imately -11 †. The vehicle is delivered from the
factory equipped with an AdBlue
®
preheating
system. Winter operation can thus 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 ser-
vice 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 respect to avoiding malfunctions
in the BlueTEC exhaust gas aftertreatment sys-
tem.
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 lon-
ger be guaranteed.
