Caution

Diesel Exhaust Fluid (DEF)

DEF is a non-toxic solution that is
sprayed into the exhaust stream of
diesel vehicles to cause a chemical
reaction and break down NOx
emissions into harmless nitrogen
and water.
DEF is not a fuel additive and never
comes into contact with diesel fuel.
It is stored in a separate tank, under
the load floor carpet in the trunk.
It has a blue filler cap. See
