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 filling capacity and consumption

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 under day-to-day operating conditions may
differ from the consumption figures calculated.
The frequency at which you will have to top up
®
AdBlue will also vary. Have the AdBlue
