They recommended at the dealership (per the owner's manual instructions) to take it easy for the first 600 miles.
The break in included:
-No hard braking
-Not maintaining a steady speed for an extended period
-Not revving very high (dealer said no more than 4k)
I followed the recommendations, and have about 1600 miles on mine and it is quiet and running perfect. It is pretty addictive to run the RPM's up, but with the surprising amount of torque it has in lower gears, you can drive efficiently when need be also.
Anyways, good luck with it!
