How often should our Nissan Qashqai's transmission fluid be changed?

How often should the transmission fluid be changed in my 2-litre petrol Nissan Qashqai? I would have thought every two years, but the Nissan Service schedule that came with my wife's car only says 'Inspect for levels and leaks' and the Nissan agent does not seem to know (or care). Can I check whether the work has been carried out?
Every 2 - 3 years.
