tion gained, this function
should only be used if traf-
fic conditions permit, and
in compliance with the local driving
regulations. Please ensure all the
conditions are met before each use.
Risk of accident or serious injury.
Heavy use of the system will reduce
the service life of the mechanical
components (clutch, transmission,
etc.).

ing assistance may no longer be opera-
tional.

again when the engine is no longer on
standby or the speed exceeds approxi-
mately 0.62 mph (1 km/h) (downhill,
slope, etc.).
For manual gearboxes:
– the gearbox is in neutral;
– and the clutch pedal is released. If
the warning light
 flashes, this
means that the clutch pedal is not
sufficiently released;
– and the vehicle speed is less than approximately 1.86 mph (3 km/h).

consumption and lower greenhouse
gas emissions.
