Proper Break-In Procedures
I'm driving any faster than 60mph. No hard breaking. No hard accelerating. Turning off A/C before turning off the engine (not sure if this is necessary though). Not revving it higher than 3000rpm. Also driving duration is about 1 hour. Is there anything else?

Don't keep in the same speed/rpm for a long period of time. This is the good one.
Just follow the owner manual, you will be fine.
Many ppl never follow such break-in rules, they're often fine, too.
You should relax.

i have been told to break in a car the way you will regularly drive it--except do not push what is a redline and also do not brake too hard early on.
I know we have been told change oil at 5000 miles--I like to change oil at 1000 miles the first time--it may be an old story thing but there used to be sand in the engine block from building the engine--and early oil change wil get that sand out-
also there are magnetic plugs for the oil drain plug--the benefit here is that if there are any slivers of metal in the engine the magnetized plug grabs it and keeps it from screwing up the engine.

10 years ago I drove a practically brand new Vette cross country--I varied the speeds--sometime 75, sometimes 105 and once 135.
But never hit the brakes hard nor accellerated fast. :-)
BTW--RPMS at 135 were not close to red line.
But--comparing the two cars--the vette and RX450? Totally different -both great in their own ways.

I have been easy going on the new RX (driving in eco mode helps the hard accelaration) and was also (slightly) worried about break in. I am driving to Ohio tonight for labor day and we only have 200 miles on the odo, so this will be our first major trip. I basically am taking the manuals advice, but from what you guys are saying, should I avoid cruise control in during this trip?
