The rev counter indicates the number of engine revolutions per minute.
You should select a lower gear if the engine speed drops below 1500 rpm. The start of the red zone on the dial indicates the maximum engine speed which may be used briefly in all gears after the engine has been run in properly. However, it is advisable to change up a gear or move the selector lever to D/S (or lift your foot off the accelerator) before the needle reaches the red zone.
Caution!
The rev counter needle -2- Fig. 1 must only ever briefly go into the red zone on the scale; otherwise there is a risk of engine damage. Where the red zone starts on the dial depends on the operating temperature of the engine.
For the sake of the environment
Changing up a gear early will help you to save fuel and minimise engine noise.
Note
When the engine is cold, the engine speed is limited so that the full range of engine power is not available. Once the engine has reached operating temperature, the red zone on the rev counter moves to a higher range of engine speeds.
