The tachometer shows the engine speed in revolutions per minute (rpm). The tachometer can help you choose a more economical driving mode and also warns you when the engine speed exceeds the maximum permissible value.
Attention: While driving, watch the tachometer readings. Its needle, which shows the engine crankshaft speed, should not enter the red zone (the zone where the maximum permissible speed is exceeded). This can lead to serious engine damage and deprive you of the right to warranty service.
