System Activation
The activation of the system is indicated by the symbol lighting up on the display. In this
condition, the light on the button is off.
System Deactivation
A message will appear on the display when the
system is deactivated. In this condition, the
light on the button is on.
NOTE:
Each time the engine is started, the system is
activated regardless of where it was when it
was previously switched off.
Possible Reasons The Engine Does Not
Autostop
For higher comfort and increased safety, and
to reduce emissions, there are certain condi -
tions where the engine will not autostop
despite the system being active, such as:
Engine still cold.
Extreme cold outside temperature.
Battery not sufficiently charged.
Driver's door not shut.
Driver's seat belt not fastened.
REVERSE (R) gear engaged (e.g. for parking
maneuvers).
With the automatic climate control active,
an adequate cabin heating or cooling
comfort has not been reached or with
MAX-DEF function active.
During the first period of use, to initialize the
system.
Steering angle beyond threshold.
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 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.
