here the link of a russian site where you can find almost everything about service & maintenance of the i-miev.
I found it by chance, when I was looking for informations for the 2Din radio cover, and also the specific gearbox cover.
Edit 17 November, 2016: revised links (thank you elekTrond)
Also, here the CD version (choose MY2011 or MY2012),
Caution: Safety of these links (virus, trojan, ...) is unknown.
