When to change timing belt Volvo S60 automatic?

You should check your owners/maintenance manual. if you don't have either call your local dealer. these cars will last a very long time if you keep after your maintenance. It's a good idea to change those items at the proper intervals i do suggest changing the oil at no more than 5000 miles, these engines today run hotter and the oil tends to "bake"inside the engine-not a good thing.
