PenMan,
I used to work for that company, I argued about that note at countless meetings. It isn't the engine (per se) that they are worried about, it is the turbocharger....
The thinking was that they don't want an operator (while the vehicle is under warranty) to start the engine and immediately try to use the full power at full boost. Like so many things, the note is intended to be safe for them. By the way, 3 to 5 minutes is to allow for an unheated start up in Bemidji, (like -50°F - aka CMF) where we did cold testing. If you are in shirt sleeves, it takes less than a minute to get lube oil to the turbocharger and that is the big issue.
Matt - this is why they hired a diesel engineer

I've seen a couple of posts in this thread that say not to idle a diesel. Wonder why my owner's manual says to idle mine to warm it up when cold? Like 3 to 5 minutes.
