Tachometer
The red zone of the tachometer scale warns that the engine is running at the maximum permissible crankshaft speed. As soon as the needle enters this zone, reduce the throttle or shift to the next gear.
Timely gear shifting saves fuel and reduces noise.
Downshifting is recommended when the engine power drops to the point where it can no longer pull in a higher gear.
