Stop&Start
ON
Conditions required to activate automatic engine stop
To activate the automatic engine stop while driving:
●
the Stop&Start system must be ON
●
the driver's seat belt must be fastened
For safety reasons and to guarantee driving comfort and correct operating
of the entire vehicle, automatic engine switching-off is deactivated when:
●
the accelerator pedal is depressed;
●
a potentially dangerous situation is identified (steep road, vehicle
stationary with wheels turned, i.e. when turning at a crossroads or
on a roundabout);
●
the system recognises vehicle motion in slow traffic or a parking
manoeuvre (checking reverse gear engagement, time elapsed since
last stop, driving speed);
●
maximum air conditioning and heating system performance is
requested ("low", "max defrost" or "rear screen demisting");
●
external temperatures are very low or very high;
●
the gearbox is in the "N" position;
●
the "LIFT" system has been activated (if present);

●
the DCT gearbox Park Lock has been manually released;
●
a failure interferes with proper system operating.
The system also constantly monitors some of the vehicle operating
parameters (battery charge level, engine coolant temperature, catalytic
converter temperature, clutch oil temperature, vacuum level in brake
servo, climate comfort in passenger compartment) so that engine
switching off can be deactivated in certain conditions to guarantee safety
and vehicle operating and minimise the impact on on-board climate
comfort.
Important note
After the first cold start, the Stop&Start system may take a few
minutes before it is ready. This time period allows some of the engine
parameters (catalytic converter temperature, for example) to reach the
values required to reduce emissions.
Important note
After disconnecting the battery from the electrical system and
reconnecting it, the Stop&Start system is not available the first time
the engine is started. To reuse the system, the vehicle must be left
parked for 6 hours once the battery has been reconnected. This period
of time is needed to calibrate the battery sensor.
Important note
If the engine continues to run when the vehicle is stationary and the
brake pedal is pressed, even if the Stop&Start system appears to be
activated, it means that the system has disabled automatic switching
off of the engine. When this happens, no specific signal is displayed on
the instrument panel: this is to be considered normal.
