AdBlue is a water-soluble fluid for the NOx
exhaust gas aftertreatment of diesel engines.
It may be improper or punishable in some coun-
tries to operate a vehicle that uses no AdBlue
one that does not comply with the specifications
of this Owner's Manual.
* NOTE Malfunctions due to the dilution of

AdBlue or the use of additive-enhanced

AdBlue
The function of the NOx exhaust gas after-
treatment can be impaired by the use of

AdBlue consumption
®
The average AdBlue consumption is between 1%
and 5% of fuel consumption. Like fuel consump-
®
tion, AdBlue consumption is highly dependent
upon driving style and operating conditions. For
this reason, your vehicle's actual consumption fig-
ures in day-to-day operating conditions may differ
from the consumption figures calculated. The fre-
quency at which you will have to top up AdBlue
®
will also vary. Have the AdBlue
at a qualified specialist workshop before making
journeys outside Europe. Before a longer stay out-
side Europe, consult a qualified specialist work-
shop.
