New Prius Owner--"hi!"--and Engine "break in" question

Hi all,

I've had my 2012 Prius 4 (Sea Glass Pearl) for two weeks, and she has 600+ miles under her tires now and is halfway through her second tank of gas and I'm hooked! I love this little car (which isn't so little!) and am eager to learn as much as I can about her.

On to the question:
The owner's manual says to not drive the car at a constant speed for too long during its first x-months of use. I have a 25-minute commute on highways and that's most of the driving I do. Am I going to mess up my car by driving it between 62-72 mph so much?

Many thanks for your help!
