STARTING AND OPERATING

ENGINE RESTARTING CONDITIONS
Due to comfort, emission control, and safety
reasons, the engine can restart automatically
without any action by the driver, under special
conditions, such as:
Battery not sufficiently charged.
Reduced braking system vacuum (e.g. if the
brake pedal is pressed repeatedly).
Vehicle moving (e.g. when driving on roads
with a grade).
Engine stopping by the Stop/Start system for
more than approximately three minutes.
With the automatic climate control active, an
adjustment in cabin heating or cooling is made
or with MAX-DEF function active.
SAFETY FUNCTIONS
When the engine is stopped through the Stop/
Start system, if the driver releases their seat belt,
opens the driver's or passenger's door, or opens
the hood from inside the vehicle, the engine can
be restarted only by using the ignition.
This condition is indicated to the driver both
through a buzzer and a message on the
instrument cluster display.
ENERGY SAVING FUNCTION
If the driver does not carry out any action for more
than three minutes after the automatic engine
restart, the Stop/Start system will switch off the
engine in order to prevent fuel consumption.
In this situation, the engine can only be restarted
using the ignition device.
NOTE:
It is possible to keep the engine running by deac-
tivating the system.
IRREGULAR OPERATION
In the event of malfunction, the Stop/Start
system is deactivated.

VEHICLE INACTIVITY
In the event of vehicle inactivity (or if the battery
is replaced), special attention must be paid to the
disconnection of the battery power supply.
Proceed as follows:
Remove connector from socket to disconnect
sensor (battery status monitoring) installed on
the negative pole of the battery. This sensor
should never be disconnected from the pole
except if the battery is replaced.
Battery Power Supply
NOTE:
After setting the ignition to OFF and having closed
the driver side door, wait at least one minute
before disconnecting the electrical supply from
the battery. When reconnecting the electrical
supply to the battery, make sure that the ignition
is in the OFF position and the driver side door is
closed.
