Hummm ... that's a first. Manufacturer saying to beat the snot out of it for proper break-in. I didn't baby my Tacoma when I bought it new, and it's the tightest, best running engine I've ever had.
In my owners manual from August 05 and was in older cars as well.
Full throttle is beneficial to engine break in. Avoid the lower gears and standing starts to protect driveline parts that are wearing in as well. Your reward is less blow by which means longer engine life, more power, and lower oil consumption.
