"Shifting between Four-WheelHigh and Four-Wheel-High Lock" is on page 2-25 but read the whole chapter before you play with that system. It's entirely possible to damage the FWD system, including shearing the front axle right off, if you do not operate it correctly and under the right conditions. It is not fool proof - it will let you break it.

You do not need to be in Neutral to switch into 4 high lock. From 4 Low lock, at a low speed, press the 4 high lock button. You should feel the change. If it flashes and doesn't change, you may have a transfer case issue. If the middle light turns solid, you should be in 4 high lock.
