Proper downshifting will improve fuel economy and prolong engine life.
CAUTION!
If you skip more than one gear while downshifting or downshift at too high a vehicle speed, you could damage the engine, transmission, or clutch.
To maintain a safe speed and prolong brake life, shift down to second or first gear when descending a steep grade.
When turning a corner or driving up a steep grade, downshift early so that the engine will not be overburdened.
