How do you "Inspect" the timming belt? Can I inspect it, How? on 2009 Subaru Forester

The owners manual says that the timming belt should be inspected every 30,000 miles and replaced at 105,000 miles. I called the Subaru dealer to schedule this timming belt inspection, along with several other items, and the service person said that its not necessary. He said that he didn't know why that was in the manual as its not necessary.
