DYNAMIC STEERING TORQUE (DST)
DST uses the integration of the Electronic
Stability Control (ESC) system with the electric
power steering to increase the safety level of the
whole vehicle.
In critical situations (braking on surfaces with
different grip conditions), the ESC system
controls the steering through the DST function to
implement an additional torque contribution on
the steering wheel in order to suggest the most
correct maneuver to the driver.
The coordinated action of the brakes and
steering increases the sensation of safety and
control of the vehicle.

NOTE:
The DST feature is only meant to help the driver
realize the correct course of action through small
torques on the steering wheel, which means the
effectiveness of the DST feature is highly depen-
dent on the driver’s sensitivity and overall reac -
tion to the applied torque. It is very important to
realize that this feature will not steer the vehicle,
meaning the driver is still responsible for steering
the vehicle.
DRIVE TRAIN CONTROL (DTC) SYSTEM —
I
F EQUIPPED
Some models of this vehicle are equipped with an
All-Wheel Drive (AWD) system, which offers an
optimal drive for countless driving conditions and
road surfaces. The system reduces the slipping of
the tires to a minimum, automatically
redistributing the torque to the front and rear
wheels as needed. To maximize fuel savings, the vehicle with AWD
automatically passes to Rear-Wheel Drive (RWD)
when the road and environmental conditions are
such that they wouldn't cause the tires to slip.
When the road and environmental conditions
require better traction, the vehicle automatically
goes to AWD mode.

NOTE:
If the system failure symbol switches on, after
starting the engine or while driving, it means that
the AWD system is not working properly. If the
warning message activates frequently, it is
recommended to carry out the maintenance
operations.
ELECTRONIC STABILITY CONTROL (ESC)
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.
Oversteer
occurs when the vehicle is turning
more than it should according to the angle of
the steering wheel.
Understeer occurs when the vehicle is turning
less than it should according to the angle of
the steering wheel.
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 counteract the above conditions. System Intervention
The intervention of the system is indicated by the
flashing of the ESC Warning Light on the
instrument panel, to inform the driver that the
vehicle stability and grip are critical.
WARNING!

Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road
conditions. ESC cannot prevent accidents,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent accidents resulting from loss of
vehicle control due to inappropriate driver
input for the conditions. Only a safe, attentive,
and skillful driver can prevent accidents. The
capabilities of an ESC equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s
safety or the safety of others.

Vehicle modifications, or failure to properly
maintain your vehicle, may change the
handling characteristics of your vehicle, and
may negatively affect the performance of the
ESC system. Changes to the steering system,
suspension, braking system, tire type and
size or wheel size may adversely affect ESC
performance. Improperly inflated and
unevenly worn tires may also degrade ESC
performance. Any vehicle modification or
poor vehicle maintenance that reduces the
effectiveness of the ESC system can
increase the risk of loss of vehicle control,
vehicle rollover, personal injury and death.

“Blind Spot Alert” Function Deactivation
When the system is deactivated (“Blind Spot
Alert” mode off), the BSM or RCP systems will not
emit an audible or a visual warning.
The BSM system will store the operating mode
that was active when the engine was stopped.
Each time the engine is started, the operating
mode stored previously will be recalled and used.
ACTIVE BLIND SPOT ASSIST (ABSA)
S
YSTEM — IF EQUIPPED
The Active Blind Spot Assist (ABSA) system
function is to help avoid/limit lateral collisions
with cars located in the blind spot zones, even
changing the vehicle’s trajectory in order to keep
it in the detected lane.
The system warns the driver about the presence
of other vehicles in the detection area by illumi -
nating the warning light located within the door
mirror on the side in which the other vehicle was
detected. The system will also provide an
acoustic signal and/or vibration on the steering
wheel and/or counter-steering torque on the
steering wheel (if the respective item on the
“Driver Assistance” menu is set up and “Safety”
is selected on the radio system).
When the engine is started, the warning light
illuminates briefly to signal the driver that the
system is active (the warning light comes on even
if the system is activated through the radio
system menu). ABSA Indicator Light
Sensors
The system uses two radar sensors, located in
the rear fascia/bumper (one for each side) to
detect the presence of vehicles (cars, trucks,
motorbikes, etc.) in the rear side blind spots of
the car.
The sensors are activated when any forward gear
is engaged at a speed higher than about 6 mph
(10 km/h), or when REVERSE (R) is engaged.
The sensors are temporarily deactivated when
the car is stationary and in PARK (P).
The detection area of the system covers about a
lane on both sides of the car around 10 ft (3 m).
This area begins from the door mirror and
extends for about 20 ft (6 m) towards the rear
part of the car.
When the sensors are active the system monitors
the detection areas on both sides of the car and
warns the driver about the possible presence of
cars in these areas.
WARNING!
The accident risk persists despite the
application of torque to the steering wheel by
the ABSA system.
Applying a torque that corrects the steering
wheel alignment does not always prevent an
accident. It is always the driver's responsi
-
bility to steer, brake or accelerate, especially
after the ABSA system warning or after the
steering wheel torque intervention. The
driver is responsible for ensuring that there
are no pedestrians, other vehicles or objects
along the direction of the vehicle. Failure to
comply with these precautions may cause
serious accidents and injuries. The driver is
fully responsible for holding a safe distance
from the vehicle ahead respecting the
highway code in force in the respective
country.
In some cases, the system could apply an
improper torque to the steering wheel. This
application can be interrupted at anytime
turning the steering wheel in the opposite
direction.

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 an
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 an 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 2 mph
(4 km/h).

NOTE:
When using an automatic car wash it is recom-
mended to deactivate the system through the
settings of the radio system. The system may
detect the presence of a car, a wall or another
obstacle and activate.
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 radio system.
If the driver presses the brake pedal fully or
makes an excessive steering maneuver during
system operation, the automatic braking
function may deactivate (e.g. to allow a
possible maneuver to avoid the obstacle).
The FCW system is automatically deactivated
when operating in race mode and a warning
message will be displayed on the instrument
cluster

page 238. Driving Close To A Bend
When entering or leaving a wide bend, the system
may detect a vehicle in front you, but not in the
same driving lane. In cases such as these, the
system may intervene.
Driving Around Wide Curves
The Vehicle Ahead Is Leaving A Roundabout
On a roundabout, the system could intervene if it
detects a vehicle ahead which is leaving the
roundabout.
