1)

Check non-positive connection of clutch: To check, the vehicle must not be in ECO mode while driving. This is the only way to ensure that the clutch is engaged at the end of a gear shift. Engine and gearbox speed must not then differ by more than 120 rpm from one other while driving. If the difference is greater than this, the clutch is slipping and will have to be replaced.

2)	The vehicle is always in ECO mode after the engine is started (green warning lamp in dash panel insert lights up). If ECO mode has to be switched off for a test, press the switch for Start/Stop mode -E262- in the centre console, the green warning lamp in the dash panel insert goes out.
