Two schools

There are two schools:

1) Old School - follow the attached break in instructions from MB

2) "New" School - follow the RPM cap, and downshift cap, but feel free to drive the sh*t out of your truck at strongly varying speeds within those parameters.

Both schools - do not do any homebrew/too-old-school brake pad "bedding" - those full brake long deals from 65-15 unless emergency traffic density requires.

Both schools - go the the full term on the initial 10K oil interval - but check oil at 2500-5000-7500 - top off (not overfill) as required. The factory "oil" is a break in formula.

Enjoy !

And, by all means, do NOT use unsuitable footwear. The style police will find you.

I've declared mine "broken in" 1289 miles on the meter! That being said.... I think the break in business is most iimportant with regard to the tranny and the brakes.
