Fig. 1 Overview of instrument cluster
The rev counter indicates the number of engine revolutions per minute.
It's a good idea to keep an eye on the rev counter and gear-change indicator because you can minimise engine wear by driving at moderate engine speeds.
The start of the red zone on the dial indicates the maximum engine speed which may be used briefly in all gears when the engine is warm and after it has been run in properly. However, it is advisable to change up a gear (on vehicles with manual gearbox) or move the selector lever to "D" (on vehicles with automatic gearbox) or lift your foot off the accelerator before the needle reaches the red zone.
In general it is best to avoid high engine speeds and to follow the recommendations given by the gear-change indicator. For further information please refer to ►Link or ►Link.
Caution!
The rev counter needle -1- Fig. 1 must only ever briefly go into the red zone on the scale; otherwise there is a risk of engine damage.
For the sake of the environment
Changing up a gear early will help you to save fuel and minimise engine noise.
