b.At the bottom, after the vehicle slows
c.Before you start down the hill, while you still have engine and road speed to shift
d.Only if the brakes begin to fade
Giải thích
Once you are descending it may be impossible to shift into a lower gear, leaving you stuck in neutral with no engine braking. Waiting until partway down, until the bottom, or until the brakes fade all remove the option to select a safe gear.
