Automatic Transmission fluid for Nissan March 2005

Anybody knows what ATF uses the Nissan March 2005, I am asking because I don´t have the owner manual and other owners said that must be the original fluid made by nissan, any other fluid could be malfunction of the transmission.
My manual said:
"Genuine Nissan ATF or equivalent*. *4: Contact a Nissan dealership for more information regarding suitable fluids, including recommended brand(s) of DexronTM III/Mer
conTM Automatic Transmission Fluid."

so I assume DexronIII would be sufficient.
Many thanks I´m sure that Genuine Nissan is not in my country cause Nissan-Chile didn´t import this model, so Dexron TM III/Mercon TM ATF is equivalent.
i am currently using Motul ATF Dexron III in my micra. the better option to this oil is the Motul Multi ATF.

by the way i have changed my gearbox oil when the car mileage was around 45/50k, when do you think i should change it next?
