Control & Operation第 63 / 120 题
You are approaching a steep downgrade in a truck with a manual transmission. When should you select your gear?
a.Halfway down, once you can judge the grade
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
解析
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.
