Note:
AdBlue® freezes at a temperature of ap-
proximately -11 °C. The bus is equipped
with an AdBlue® preheating system as
standard. Winter operation is therefore
guaranteed, even at temperatures of be-
low -11 °C.
Environmental protection
AdBlue® is biologically degradable. Un-
less it is handled properly, however, Ad-
Blue® constitutes an environmental haz-
ard. Do not allow AdBlue® to enter the
sewerage system, surface water, ground-
water or soil in significant volumes.
Danger. Risk of poisoning and
injury.
AdBlue® is not classified as a hazardous
substance by German regulations govern-
ing hazardous substances. Nevertheless,
certain points should be observed when
handling AdBlue®.
The AdBlue® line system and the system
components connected to it are pres-
surised while the engine is warm. There
is a risk of scalding from hot AdBlue®
spraying out if the line system is suddenly
opened. There is also the risk of skin ir-
ritation or damage to the eyes if AdBlue®
comes into contact with the skin or eyes.

Work on the exhaust gas aftertreat-
ment system should not be com-
