no, it uses a chain. I don't know which model you are looking at but the 2012 2.0L was the first year with the chain. The 1.6L always had a chain. The 2.0L engine which was new for 2012 is called the Nu series. There is now no new KIA's sold in the US that uses a timing belt.
The Drive belt is not the timing chain. It drives components on the passengers side of the engine just like on all vehicles, but the belt is shorter now the power steering is electric driven. This is an inspection first at 60,000 miles or 72 months and then every 15,000 miles or 24 months after that. It states the drive belt should be replaced when cracks occur or tension is reduced excessively. Not sure what you were looking at that information is all there in the maintenance schedule section of the owners manual (this is from the 2013 Soul Owners Manual for the US).
