Keep on top of the service record, as its usefull for what parts need replacing after their given time or mileage.

The date and mileage are the most important factors here, it is also worth keeping an eye on the condition of the parts / fluids and replace as necesary.

Some of the above are Nissan's suggestions, and some are my own, found through experience.
