Avoid AdBlue getting onto vehicle aggregates and
soil.
In case of AdBlue ingress onto varnished or alu-
minum surfaces during system priming, be sure to rinse
the surface immediately.
It is prohibited to re-use liquid drained during
repair.
Be sure to use only plastic or stainless steel cans
for AdBlue storage.
If agent is stored in cans produced from copper,
copper alloys, plain or zincing steel, the particles of those
metals may be introduced into AdBlue agent to cause the
after-treatment system failure.
