Somewhere around page 129 in the useless book, it will tell you how to get
into 4 low....... Amazingly, getting OUT of 4 low uses the same process
except for the last step where you would move the switch to either 4 hi or 4
auto.

Take note..... the vehicle must be in neutral if an automatic (park will NOT
do) or the clutch must be depressed if a manual...... vehicle speed must be
less than 3 mph...... and your foot must be on the brake hard enough to turn
on the brake lights.
