Surfaces which have come into contact with
AdBlue
®
while refilling should be rinsed
immediately with water, or remove AdBlue
®
with a moist cloth and cold water. If AdBlue
®
has already crystallised, use a sponge and
cold water to clean the area. AdBlue
®
residue
crystallises after a certain amount of time and
soils the affected surfaces.
!
AdBlue
®
is not a fuel additive and must not
be added to the fuel tank. If AdBlue
®
is added
to the fuel tank, this can lead to engine dam-
age.
Have the AdBlue
®
tank refilled at a qualified
specialist workshop. However, you can also top
up the AdBlue
®
tank:
R
at a filling station with an AdBlue
®
filling pump
R
with AdBlue
®
refill bottles
R
with an AdBlue
®
refill canister
When the pump nozzle switches off automati-
cally during filling at a filling pump, the AdBlue
®
tank has been completely filled. Do not fill the
AdBlue
®
tank any further. AdBlue
®
may leak
out.
To avoid transporting already opened refill con-
tainers in the vehicle, completely empty refill
bottles or canisters when filling the AdBlue
®
tank, if possible.
