Important safety notes
For BlueTEC vehicles only.
DEF is a non-flammable, non-toxic, colorless, odorless and water-soluble fluid.
Rinse surfaces that have come into contact with DEF immediately with water or remove DEF using a damp cloth and cold water. If the DEF has already crystallized, use a sponge and cold water to clean it. DEF residues crystallize after time and contaminate the affected surfaces.
