The manual states that there doesn't really need to be a break-in period.

However, it cautions that within the first 1000km's, there shouldn't be any hard starts, high revving, or constant driving (for long periods of time).
:huh:

The description shown above *IS* a break-in period! This is exactly what one does to properly break-in an engine ... you avoid hard starts, high rev'ing, and constant driving at a steady speed over the first 500-1000 miles. This is how break-ins have been defined for at least 20 years.

It may not harm the car, but it isn't the best thing to do to a brand new engine. Momentary speed changes wouldn't do much to help. As in, if you are driving 200 miles and drive 196 of them at 75mph, then that's basically the same thing as driving all of them at 75.

If your trip is all interstate, then it might be best if you could get off of it and drive on a parallel 2-lane through a couple of towns for part of the way. If the trip is on 2-lane and you are driving through some towns, then you will be okay.

Also if all interstate then don't use your cruise control to maintain a steady speed/rpm for a long time.
