ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or
55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detrimental
and should be avoided.
Thats the official answer.
You would want to avoid running at any steady engine speed for any length of time during early miles. The tidbit about full throttle just means don't try to peel rubber, but that brief runs of full throttle are actually good for your engine during early miles.
Since you are on a trip, you could try playing with the paddle shifters, bumping it up and down to avoid steady engine speed. It won't let you either upshift or downshift if the resulting RPM is out of safe range.
My service reps also recommended using the sport mode a lot during early miles to help break in the engine.
