I wouldn't necessarily keep the RPMs low, but I wouldn't go over the RPM limit in the manual during the break-in miles. My manual says to limit RPM to 4K so I stay below that, but I do let the engine rev up to that point occasionally without using full throttle acceleration. Some of the components need to get seated and conformed to their mating surfaces and so I let the engine work its way up to 4K and then switch into Eco Pro and let the engine drop to a lower RPM. I plan to keep my car for at least the next 8 years so I won't abuse it, but I do recognize that the engine needs to do some work to loosen up a bit and start making all its power.
