Prius 2005 timing belt

At what millage if at all, does a 2005 Prius need it’s timing belt replaced. Neither the manual or my Hanes book list this as a maintenance item.

Are you sure it has a timing belt???

Gates doesn’t list a belt so I’ll bet it has a chain.

If it’s not listed, then it probably has a chain instead of a belt.

If it had a timing belt, the change intervals would only be in months (so many months equals so many years); not in miles.
