The aux micro-V drive belt on Honda are good for over 100,000 ( according to service manager at local Honda ) - He had an Integra that until then had done 120,000 on original belt and it was still in good shape - I went to buy one and he said 'has the old one snapped ' I said no and he asked why it needed replacing, he said they do not keep them in stock and only replace them if they are badly cracked or frayed along the edges. He could have sold me one, but reassured me that at just over 50K mine had a lot of life left. The 2006 -> Civic and 2008 -> (Mk2 ) Jazz have a spring loaded tensioner that keeps belt at optimum tension all the time, so not possible to over or under tension... Any squealing noise from the belt area on Mk2 is most likely the bearing in the tensioner pulley rather than belt slip.
The i-shift still has a clutch, but it is automated, so I would imagine that the small clutch fluid reservoir has been moved from its normal position on a manual car in front of brake reservoir ( on top of clutch master cylinder ) to somewhere nearer the clutch,
