I think the manual (not diesel supplement) has the procedures, but from memory it's probably something like no speeds over 55mph, don't drive at a constant speed, no towing for first 500 miles. To be honest, I've been a bit of a skeptic on engine break in for modern cars; I've had cars up over 100k mileage that I drove like a beast from day 1 and cars that had so many problems in the first 1000 miles while driving it like a baby (I'm looking at you Ford!).
