able oils is not permitted.
BlueTec exhaust gas cleaning
system
The BlueTec exhaust gas cleaning system
essentially comprises a tank, catalytic
converter and AdBlue metering system.
It is electronically monitored and con-
trolled. Pollutants in the exhaust gas are
converted into environmentally-friendly
substances by the addition of AdBlue
and the catalytic converter integrated
into the silencer.
The BlueTec exhaust gas cleaning system
must be operated with a reducing agent
(AdBlue) for it to work correctly. Filling
with AdBlue is not part of the scope of
maintenance jobs and must be done by
the operating personnel regularly dur-
ing operation of the vehicle. Filling and
operating the bus with AdBlue is man-
datory for compliance with emission
regulations and thus one of the condi-
tions for the road traffic approval of the
bus. The road traffic approval of the bus
will be invalidated if the bus is operated
without AdBlue. The legal consequence
would be that the bus would no longer

BlueTec exhaust gas cleaning system

be permitted to be operated on public
roads. In some countries, operating the
bus without AdBlue may incur a fine or
be considered a misdemeanour. Sup-
port in the purchase or operation of the
bus, e.g. tax relief, road tax, may also
be invalidated retrospectively. This may
be the case both in the country in which
the vehicle is registered and in other
countries in which the vehicle is oper-
ated.
Danger.
It is essential that work relevant to safety
or work on safety-related systems be car-
ried out at a qualified specialist work-
shop.
Danger.
Always have maintenance work carried
out at a qualified specialist workshop
which has the necessary knowledge and
tools.
