Auris D-4D 2.0L. How do I handle it properly?

Hi guys, I bought myself a new Auris 2.0L diesel. With over 40% discount I just couldn’t say NO. I’ve never had a new car and even more so no diesel. How do I really deal with it in terms of “drive in”? What do I have to think about? I hear about something like “the first 2000km don’t drive over 100km/h” or “the Diesel MUST run warm, short drives to the Aldi break that” etc. :-O What’s the point? My Toyota dealer says that all Toyota models over This software locks off the car in such a way that initially only about 70% of its nominal power is available to it. In the course of the next 5,000-8,000km, the vehicle unlocks itself again. This is to prevent customers from driving with new cars with squeaking tires from the yard and a week later with a turbocharger damage again in the door hinge – a sensible principle, but is it true? In short: What do I have to do when driving in my new Auri think? MfG Laurooon
