Subaru Impreza service manual

Hello dear fellows,

I have no experience at all with Subaru - just trying to help a friend of mine which owns a Subaru Impreza. The model is 2008-2009, type G3/GHD/OJO, 1998 cmc, 110 kW, boxer diesel.
My small request is for a service manual (mechanical & electrical) for this version or for any model close to it.

Thank you for you time,
laur.
