Avoid impurities in AdBlue
#
®
AdBlue
residues crystallise after a period of
time, and contaminate the surfaces with which
they come into contact. Clean the dirty surfaces
with water as soon as possible.
®
When you open the AdBlue
tank, small amounts
of ammonia vapour may escape. Do not inhale
any ammonia vapours that may be released. Only
®
fill the AdBlue
tank in well-ventilated areas.

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 average consumption figures calculated.
The frequency at which you will have to top up
®
AdBlue
will also vary. Have the AdBlue
checked at a qualified specialist workshop before
making journeys outside Europe. Before a longer
stay outside Europe, consult a qualified specialist
workshop.
