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

positions also provide greater engine braking for going down grades (the
lower the range, the greater the braking effect).

power and maximum engine braking power.
