when do i have to change the timing belt on 2007 Kia Sportage

I have read different things (my last car's manual stated 60,000 but I changed it at 90,000). When do I REALLY have to change the timing belt?

It is recommended to replace the Timing Belt on these trucks every 60,000 Miles. I would replace the water pump at the same time.
