Note
- Only use Ad Blue that conforms to the
standard ISO 22241-1. Do not mix any addi-
tives with the AdBlue and do not dilute it
with water.
- Do not add Ad Blue to the diesel tank or add
diesel fuel to the AdBlue tank. Mixing can
lead to damage to the engine and the Ad Bl-
ue tank system .
- Ad Blue attacks surfaces such as painted ve-
hicle components, plastic and carpet . Re-
move the fluid as quickly as poss ible with a
damp cloth and plenty of cold water. If the
AdBlue has already crysta llized, use warm
water and a sponge. Ad Blue residue that is
not removed will crysta llize and can damage
the affected surface.
- Do not store refill bottles or canisters per-
manently in the vehicle. If the container
leaks, the escaping Ad Blue could damage
the vehicle interior.
- Do not allow Ad Blue to come into contact
with clothing. If there is contact with the
fluid, flush immediately with plenty of wa-
ter.
