i used to sell nissans a few years back (05-07)
if it truely is a certified pre-owned nissan, it would have the 100000mile powertrain warrenty. what they probally tried to sell you was the 100000mile "wraparound" warrenty, which covers everything except wearable items (brakes, tires, belts, etc.)
the timing chain would be covered by powertrain warrenty. doublecheck with the dealer to make sure you really did get the certified preowned powertrain warrenty that goes 10 years/100000milles.
otherwise your covered untill 60000miles/5 years from first in service date.
