The rev. counter shows engine rpm. The needle pointed to the danger area (red on certain versions) indicates excessive high engine speed. Do not drive for long periods with the needle in this area.

IMPORTANT The electronic injection control system gradually shuts off the flow of fuel when the engine is “over-revving” resulting in a gradual 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.
