Rev. counter B-fig. 33 - 34 shows engine rpm.

IMPORTANT
The electronic system progressively blocks fuel flow to prevent engine from overrevving. This will lead to a progressive loss of engine power. When the engine is idling, the rev counter may indicate a gradual or sudden highering of the speed.
This is normal as it takes place during normal operation, for example when activating the climate control system or the fan. In particular a slow change in the speed preserves the battery charge.
