q Notes on reNlling AdBlue n
AdBlue n
is a water-soluble Ouid for the NOx
exhaust gas asertreatment of diesel engines. In
order for the exhaust gas asertreatment to func-
tion properly, only use AdBlue n
in accordance
with ISO 22241.
AdBlue n
is characterised by the following:
= non-toxic
= colourless and odourless
= non-Oammable
If you open the AdBlue n
tank, small amounts of
ammonia vapour may be released. Only Nll the
AdBlue n
tank in well-ventilated areas.
Do not let AdBlue n
come into contact with skin,
eyes or clothes. Keep AdBlue n
