Occasionally, the road, load, or traffic conditions will make it desirable to
restrict the automatic shifting to a lower range. (When conditions
improve, return the selector to the normal
D (Drive) position.) The
positions also provide a greater engine braking for going down grades
(the lower the range, the greater the braking effect).

Use this range when pulling through mud and snow or driving up or down
steep grades. This range provides the vehicle with maximum driving
power and maximum engine braking power.
