I just found this online web site where you can dowload electronic version of Honda and Acura Owner's Manual. There are also others stuffs that can be download but of less interest for me.

But I really would like to get a hold on a 2006 HCH service manual if someone know how I can get one....

An electronic version can always be fun to have...

Have fun. (Hope it's not a repost)

There is also a manual named: Honda Emergency Response Guide (Hybrid Vehicles)

Thanks Soleil24 - they had a preliminary owners manual which will be very useful.
