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 approx. 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 igni
-
tion.
This condition is indicated to the driver both
through a buzzer and a message on the instru
-
ment 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
deactivating the system.
Irregular Operation
In the event of malfunction, the Stop/Start
system is deactivated.
For failure indications, refer to "Warning Lights
and Messages" paragraph in "Getting To Know
Your Instrument Panel".
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 mode and the
driver side door is closed.
