Every 60,000 miles
Dealer says to replace it at 60k miles if not a little sooner. Mine personally waited till 94k or so and the mechanic literally almost fell out of his chair hearing this and said I was extremely lucky as these timing belts are know for breaking not long after 60k. The timing belt swap cost $345 for me.
