Additionally the fumes in the tank are
captured in the canister and do not
emerge.
Since AdBlue has a limited
durability, check the date of expiry
before refilling.
Note
A volume of at least 5 litres of AdBlue
must be refilled. Otherwise the
refilling of AdBlue might not be
detected by the system.
If AdBlue has to be refilled at
temperatures below -11 °C, the
refilling of AdBlue might not be
detected by the system. In this case,
park the vehicle in a place with a
higher ambient temperature until
AdBlue is liquefied.
Note
When unscrewing the protective cap
from the filler neck, ammonia fumes
might emerge. Do not inhale as the
fumes have a pungent smell. The
fumes are not harmful by inhalation.
The vehicle must be parked on a level
surface.
