The service intervals are every 3.5k miles (1st check is at 600 miles, then 4000, 7500, 11000, 14500 etc).
The major service is every 14k miles as that is when the valve clearance are supposed to be checked.
Every 7k miles the throttle body sync is supposed to be checked and that needs the right computer software to do from 2007 models onwards.
