As to its correctness I cannot comment, but can see why there is confusion. Maybe it was chains for US market and belts in UK.

The 2011 Volvo XC60 comes equipped with a timing chain instead of a timing belt. The chain is designed to last the life of the vehicle, and as a metal part, by default, is more durable. Also because it operates from inside rather than outside the engine, it doesn't suffer from cracking or drying out like belts do. They can improve fuel economy as well. Most belts need replacing between 60,000-100,000 miles. The Forester's timing chain should remain maintenance free. Occasionally they break or the tensioner stretches, which can have catastrophic results for the engine. If You're finding metal shavings in the oil, experiencing mIS Fires or hearing a rattling noise while idling, make an appointment to have it examined.
