Convert FR-V 2.2 i-CTDI to Euro5

Hello to the forum, I have a FR-V Diesel, model 2007 since yesterday. When reading the COC and the exhaust gas values found in it, I noticed that all values comply with the Euro5. Can someone help me how to get the registration of the Euro5 – at the moment Euro4 is included, logically because in June 2008 the Euro5 did not exist yet. What do your experiences say? Thank you very much.
