Depends on what gearbox it has, I have a 2002 model same as you and it's the 5 litres one, but a friend has a same year model and it has the 3.whatever litre box in it.
On the inside of your bonnet on the right hand side there should be a sticker saying something about only use Nissan NS-1 CVT fluid, on the label should be the model number of the gearbox, what is it?
