ACTIVE SAFETY SYSTEMS
The vehicle may be equipped with the
following active safety devices:
Anti-Lock Braking (ABS) System
Drive Train Control (DTC) System
Electronic Stability Control (ESC)
System
Traction Control System (TCS)
Panic Brake Assist (PBA) System
Hill Start Assist (HSA) System
Dynamic Steering Torque (DST)
System
Active Torque Vectoring (ATV) System
For the operation of the systems, see the
following pages.
Anti-Lock Braking (ABS) System
An integral part of the braking system,
the ABS prevents one or more wheels
from locking and slipping in all road
surface conditions, regardless of the
intensity of the braking action. The
system ensures that the vehicle can be
controlled even during emergency
braking, allowing the driver to optimize
stopping distances.
The system intervenes during braking
when the wheels are about to lock,
typically in emergency braking or
low-grip conditions where locking may be
more frequent. The system also improves control and
stability of the vehicle when braking on a
surface where the grip of the left and
right wheels varies, such as in a corner.
The Electronic Braking Force Distribution
(EBD) system works with the ABS,
allowing the brake force to be distributed
between the front and rear wheels.
System Intervention
The ABS equipped on this vehicle is
provided with the "Brake-by-wire"
(Integrated Brake System - IBS) function.
With this system, the command given
by pressing the brake pedal is not
transmitted hydraulically, but electrically.
Therefore, the light pulsation that is felt
on the pedal with the traditional system
is no longer noticeable.
Warning!
The ABS contains sophisticated electronic
equipment that may be susceptible to
interference caused by improperly installed
or high output radio transmitting equipment.
This interference can cause possible loss of
anti-lock braking capability. Installation of
such equipment should be performed by
qualified professionals.
Pumping of the Anti-Lock Brakes will
diminish their effectiveness and may lead to
a collision. Pumping makes the stopping
distance longer. Just press firmly on your
brake pedal when you need to slow down or
stop.
The ABS cannot prevent the natural laws
of physics from acting on the vehicle, nor
can it increase braking or steering efficiency
beyond that afforded by the condition of the
vehicle brakes and tires or the traction
afforded.
The ABS cannot prevent collisions,
including those resulting from excessive
speed in turns, following another vehicle too
closely, or hydroplaning.
The capabilities of an ABS equipped
vehicle must never be exploited in a reckless
or dangerous manner that could jeopardize
the user’s safety or the safety of others.
Electronic Stability Control (ESC)
System
The ESC system improves the directional
control and stability of the vehicle in
various driving conditions.
The ESC system corrects the vehicle’s
understeer and oversteer, distributing
the brake force on the appropriate
wheels. The torque supplied by the
engine can also be reduced in order to
maintain control of the vehicle.
The ESC system uses sensors installed
on the vehicle to determine the path that
the driver intends to follow and
compares it with the vehicle’s effective
path. When the real path deviates from
the desired path, the ESC system
intervenes to counter the vehicle’s
understeer or oversteer.

SAFETY

If an obstruction is signaled, clean the
area of the windshield.
Although the vehicle can still be driven in
normal conditions, the system may be not
completely available.
When the conditions limiting the system
functions end, this will go back to normal
and complete operation. Should the fault
persist, contact your authorized dealer.
System Failure Signaling
If the system turns off and a dedicated
message is shown on the display, it
means that there is a fault with the
system.
In this case, it is still possible to drive the
vehicle, but you are advised to contact an
authorized dealer as soon as possible.
Radar Indication Not Available
If conditions are such that the radar
cannot detect obstacles correctly, the
system is deactivated and a dedicated
message appears on the display. This
generally occurs in the event of poor
visibility, such as when it is snowing or
raining heavily.
The function of this system can also be
temporarily reduced due to obstructions
such as mud, dirt or ice on the bumper. In
such cases, a dedicated message will be
shown on the display and the system will
be deactivated. This message can
sometimes appear in conditions of high
reflectivity (e.g. tunnels with reflectivetiles or ice or snow). When the conditions
limiting the system functions end, it will
go back to normal and complete
operation.
In certain cases, this dedicated message
could be displayed when the radar is not
detecting any vehicles or objects within
its view range.
If atmospheric conditions are not the
reason behind this message, check if the
sensor is dirty. It could be necessary to
clean or remove any obstructions in the
area.
If the message appears frequently, even
in the absence of atmospheric conditions
such as snow, rain, mud or other
obstructions, contact your authorized
dealer for a sensor alignment check.
In the absence of visible obstructions,
manually removing the decorative cover
trim and cleaning the radar surface could
be required. Have this operation
performed at your authorized dealer.
Note:
It is recommended that you do not
install devices, accessories, or
aerodynamic attachments in front of the
sensor or darken it in any way, as this can
compromise the correct functioning of
the system. Frontal Collision Alarm With Active
Braking
If this function is selected, the brakes are
operated to reduce the speed of the
vehicle in the event of potential collision.
This function applies an additional
braking pressure if the braking pressure
applied by the driver does not suffice to
prevent potential collision.
The function is active with speed above
4 mph (7 km/h).
Driving In Special Conditions
In certain driving conditions, system
intervention might be unexpected or
delayed. The driver must therefore be
very careful, keeping control of the
vehicle.
Driving close to a bend.
The vehicle ahead is leaving a
roundabout.
Vehicles with small dimensions and/or
not aligned in the driving lane.
Lane change by other vehicles.
Vehicles traveling at right angles to the
vehicle.
Note: In particularly complex traffic
conditions, the driver can deactivate the
system manually through the Information
and Entertainment System.

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 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 conditions where the engine will
not autostop despite the system being
active, such as:
Engine still cold.
Especially cold outside temperature.
Battery not sufficiently charged.
Driver's door not shut.
Driver's seat belt not fastened.
Reverse 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 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 ignition.
This condition is indicated to the driver
both through a buzzer and a message on
the instrument cluster display.
Irregular Operation
In the event of malfunction, the
Stop/Start system is deactivated.
For failure indications, see the "Warning
Lights and Messages" paragraph,
"Getting To Know Your Instrument Panel"
chapter.
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.
147

Recalling The Speed
Once the system has been deactivated,
but not canceled, the previously set
speed can be recalled by pushing the RES
button and removing your foot from the
accelerator. The system will be set to the
last stored speed.
Note:Before resuming the previously
set speed, you must accelerate to a
speed close to that speed.
In Autostick (sequential) mode, before
resuming the previously set speed, you
should accelerate until you are close to
that speed. Then, push and release the
RES button.
Deactivating
Lightly pressing the brake pedal
deactivates the speed control without
deleting the set speed.
The speed control may also be deactivated
by applying the electric park brake or
when the braking system is operated
(e.g. operation of the ESC system).
The set speed is deleted in the following
cases:
Pushing the on/off button a second
time.
The ignition is cycled to STOP.
If there is a malfunction with the
Speed Control.
ADAPTIVE CRUISE CONTROL
(ACC) — IF EQUIPPED
System Description
The Adaptive Cruise Control (ACC) is a
driver assist system that combines the
speed control functions with controlling
the distance from the vehicle ahead.
The system allows to set and hold the
vehicle at the desired speed without
needing to press the accelerator. It also
allows to set and hold a distance from the
vehicle ahead (these settings are set by
the driver).
The Adaptive Cruise Control (ACC) uses a
radar sensor located behind the front
bumper and a camera located in the
center/upper part of the windshield, to
detect the presence of a vehicle close
ahead.

This system enhances driving comfort
while on the highway or out of town with
light traffic.
If the sensor does not detect a vehicle
ahead, the system will maintain a fixed
set speed.
If the sensor detects a vehicle ahead, the
system automatically intervenes by
braking (or accelerating) slightly in order
not to exceed the original set speed, so
that the vehicle keeps the preset
distance, seeking to adapt to the speed
of the vehicle ahead.
Note:
Adaptive Cruise Control
performance is not guaranteed under the
following circumstances, and it is
recommended to turn the system off
when:
Driving in fog, heavy rain, or snow.
Driving in heavy traffic or
construction zones.
Driving on icy, snowy, slippery roads,
roads with steep climbs and descents, or
roads with numerous turns and bends.
Entering a turn lane.
When circumstances do not allow
safe driving at a constant speed.
Warning!
Adaptive Cruise Control (ACC) is a
convenience system. It is not a substitute
for active driving involvement. It is always
the driver’s responsibility to be attentive
of road, traffic, and weather conditions,
vehicle speed, distance to the vehicle ahead;
and, most importantly, brake operation to
ensure safe operation of the vehicle under
all road conditions. Your complete attention
is always required while driving to maintain
safe control of your vehicle. Failure to follow
these warnings can result in a collision and
death or serious personal injury.
The ACC system:
Does not react to pedestrians, oncoming
vehicles, and stationary objects (e.g., a
stopped vehicle in a traffic jam or a disabled
vehicle).
Cannot take street, traffic, and weather
conditions into account, and may be limited
upon adverse sight distance conditions.
Does not always fully recognize complex
driving conditions, which can result in wrong
or missing distance warnings.
Will bring the vehicle to a complete stop
while following a target vehicle and hold the
vehicle for approximately 3 minutes in the
stop position. If the target vehicle does not
start moving within 3 minutes the parking
brake will be activated, and the ACC system
will be canceled.
You should switch off the ACC system:
When driving in fog, heavy rain, heavy
snow, sleet, heavy traffic, and complex
driving situations (i.e., in highway
construction zones).
When entering a turn lane or highway off
ramp; when driving on roads that are
winding, icy, snow-covered, slippery, or have
steep uphill or downhill slopes.
When circumstances do not allow safe
driving at a constant speed.
Activation/Deactivation
The system has four operating states:
Enabled (speed not set)
Activated (speed set)
Paused
Deactivated
Enabling/Activating
To enable the system, push and release
the
button located on the left side on
the steering wheel.

STARTING AND OPERATING

When the ESC (or ABS or other
stability control systems) are operating
or have just operated.
When the ESC system is off.
When the Forward Collision Warning
system is braking automatically.
In the event of system failure.
When the engine is OFF.
In case of obstruction of the radar
sensor (in this case the bumper area
where it is located must be cleaned).
If the system is set, the conditions
described above also cause a
cancellation or deactivation of the
system. These situations may vary
according to the conditions.
Note: The system will not be deactivated
when speeds higher than those set are
reached by pressing the accelerator
pedal above 110 mph (180 km/h). In
these situations, the system may not
work correctly and it is recommended to
deactivate it.
To Vary The Speed Setting
Increasing Speed
Once the system has been activated, you
can increase the speed by pushing the
SET switch upward. Each time the switch
is pushed, the speed increases by 1 mph. By pushing and holding the switch
upward, the set speed will increase in
increments of 5 mph until the switch is
released. Then, the new speed will be set.
Decreasing Speed
Once the system has been activated, you
can decrease the speed by pushing the
SET switch downward. Each time the
switch is pushed, the speed decreases
by 1 mph.
By pushing and holding the switch
downward, the set speed will decrease in
increments of 5 mph until the switch is
released. Then, the new speed will be set.
Note:
Moving the SET switch allows you to
adjust the speed according to the
selected unit of measurement ("US" or
"Metric") set on the Information and
Entertainment System (see dedicated
supplement).
When the unit of measurement is set
to Metric, pushing and holding the SET
switch will adjust the speed in 10 km/h
increments.
By keeping the accelerator pedal
depressed, the vehicle can continue to
accelerate beyond the set speed. In this
case, use the SET switch to set the
speed to the vehicle’s current speed.
When you push the SET button to
reduce the speed, the braking system
intervenes automatically if the engine
brake does not slow the vehicle down
sufficiently to reach the set speed. The
device holds the set speed uphill and
downhill; however a slight variation is
entirely normal, particularly on slight
inclines.
The transmission could shift to a
lower gear when driving downhill, or
when accelerating. This is normal and
necessary to maintain the set speed
The system will disable while driving
if the brakes overheat.
Accelerating When Overtaking
When driving with ACC activated and
following a vehicle, the system will
provide an additional acceleration up to
the ACC set speed to assist in passing the
vehicle. This additional acceleration is
triggered when the driver utilizes the left
turn signal and will only be active when
passing on the left hand side.
The system detects the direction of
traffic automatically when the vehicle
passes from left-hand traffic to
right-hand traffic. In this case, the
overtaking assist function is only active
when the reference vehicle is overtaken
on the right. The additional acceleration
is deactivated when the driver uses the
right direction indicator and returns to
the original lane.
