Selective Catalytic Reduction System
Risk of damage due to reducing agent
If any reducing agent contacts the trim or body components, the reducing agent can crystallize after a period of time and damage the surface.
-- Make sure the reducing agent does not contact any trim or vehicle body components.
-- If any contact occurs on surfaces, remove the reducing agent immediately using water and a towel.
