HIGHWAY ASSIST SYSTEM
(HAS) — IF EQUIPPED
The Highway Assist System (HAS) is a driving
assistance system that is only available when
driving on highways. The system operates up
to speeds of 90 mph (145 km/h) when hori -
zontal signs are detected.
The system uses information from the front
camera and radar to help keep the vehicle in
the center of the lane and at a constant speed.
The HAS system combines Adaptive Cruise
Control (ACC) functions with lane centering
logic to control the trajectory of the vehicle.
The HAS system requires the driver’s hands to
remain on the steering wheel.
Once HAS is activated, a dedicated screen will
appear on the instrument cluster display.
To Activate/Deactivate
To Activate
To activate the HAS system, push the button
located on the left side of the steering wheel. Highway Assist Button

When the HAS system is turned off, the
symbol on the display turns red and then
grey.
Hands on the steering wheel are detected
by a capacitive sensor installed in it.
When the automatic suspension conditions
are over, HAS will be automatically reacti -
vated.
Operation
The HAS system only operates when the
driver’s hands are on the steering wheel.

2 — Suggested Speed Lower Than Current Speed
1 — Road Sign Recognized
PARKSENSE FRONT/REAR
PARK ASSIST SYSTEM — IF
EQUIPPED
The ParkSense system provides visual and
audible indications of the distance between
the rear, and if equipped, the front fascia/
bumper and a detected obstacle when
backing up or moving forward (e.g. during a
parking maneuver). The vehicle brakes may be automatically applied and released when
performing a reverse parking maneuver if the
system detects a possible collision with an
obstacle.
When the REVERSE gear is engaged and the
system is on, the front and rear sensors are
activated. If the vehicle moves from REVERSE
to a forward gear, the rear sensors are deacti
-
vated, while the front sensors remain active
until the speed of 9 mph (15 km/h) is exceeded.

NOTE:

In certain operating conditions, the system
could start detecting an obstacle only after the
vehicle has moved slightly (a few inches).
ParkSense Sensors
The ParkSense sensors located in the rear
fascia/bumper and (if equipped) in the front
fascia/bumper, monitor the area in front and
behind the vehicle that is within the sensors’
field of view. These sensors detect the pres -
ence of any obstacles and warn the driver
through an acoustic signal and visual indica -
tions, which will be displayed on the instru -
ment cluster display.
WARNING!
Drivers must be careful when backing up
even when using the ParkSense system.
Always check carefully behind your vehicle,
and be sure to check for pedestrians,
animals, other vehicles, obstructions, or
blind spots before backing up. You are
responsible for the safety of your
surroundings and must continue to pay
attention while backing up. Failure to do so
can result in serious injury or death.
CAUTION!
The ParkSense system is only a parking
aid and it is unable to recognize every
obstacle, including small obstacles.
Parking curbs might be temporarily
detected or not detected at all. Obstacles
located above or below the sensors will
not be detected when they are in close
proximity.
The vehicle must be driven slowly when
using the ParkSense system in order to be
able to stop in time when an obstacle is
detected. It is recommended that the
driver looks over his/her shoulder when
using the ParkSense system.

ParkSense System Usage Precautions

NOTE:

Some conditions may influence the perfor-
mance of the ParkSense system:
Reduced sensor sensitivity could be due to
the presence of ice, snow, mud, or thick
paint on the surface of the sensor.
The sensors may detect a false obstacle
(echo interference) due to mechanical inter -
ference, for example when washing the
vehicle or in extreme weather.
The signals sent by the sensors can be
altered by the presence of ultrasonic
systems (e.g. pneumatic brake systems of
trucks or pneumatic drills) near the vehicle.
System performance can be influenced by
the position of the sensors. For example,
due to a change in the ride setting (caused
by wear to the shock absorbers or suspen -
sion), by changing tires, overloading the
vehicle or operations that require the
vehicle to be lowered.
Be sure not to place bumper stickers or
other adhesives over the sensors as this will
affect system performance.
The presence of a trailer hitch without a
trailer. This may interfere with the operation
of the parking sensors. Before using the
ParkSense system, it is recommended to remove or close the trailer hitch assembly
when the vehicle is not being used for
towing.
LANE DEPARTURE WARNING
(LDW) SYSTEM
Lane Departure Warning Operation
The Lane Departure Warning system uses a
forward looking camera located on the wind
-
shield to detect lane markings and measure
vehicle position within the lane boundaries.
When one or both lane limits are detected and
the vehicle passes over one without an acti -
vated turn signal, the system emits a visual as
well as an acoustic signal.
If the vehicle continues to go beyond the line
of the lane without any intervention from the
driver, the surpassed line will light up on the
display (left or right) to urge the driver to bring
the vehicle back into the limits of the lane.
CAUTION!
Projecting loads on the roof of the vehicle
may interfere with the correct operation of
the camera. Before starting, make sure
the load is correctly positioned in order
not to cover the camera operating range.
Do not cover the operating range of the
camera with stickers or other objects.
Do not tamper with nor operate on the
camera. Do not close the openings in the
aesthetic cover located under the interior
rearview mirror. In the event of a failure of
the camera, contact your authorized
dealer.
The camera may have limited or absent
operation due to weather conditions such
as: heavy rain, hail, thick fog, heavy snow,
formation of ice layers on the windshield.
Camera operation may also be compro -
mised by the presence of dust, condensa -
tion, dirt or ice on the windshield, by traffic
conditions (e.g. vehicles that are driving
not aligned with yours, vehicle driving in a
transverse or opposite way on the same
lane, bend with a small radius of curva -
ture), by road surface conditions and by
driving conditions (e.g. off-road driving).
Make sure the windshield is always clean.
Use specific detergents and clean cloths
to avoid scratching the windshield. The
camera operation may also be limited or
absent in some driving, traffic and road
surface conditions.
If the windshield must be replaced due to
scratches, chipping or breakage, contact
exclusively an authorized dealer. Do not
replace the windshield on your own. It is
advisable to replace the windshield if it is
damaged in the area of the camera.
CAUTION! (Continued)

SAFETY

Given that, in a turn, the external wheels of the
car travel more than the internal ones and
therefore turn faster, sending a higher thrust
to the external rear wheel allows for the car to
be more stable and to not suffer an "under-
steer" condition. Understeer occurs when the
vehicle is turning less than appropriate for the
steering wheel position.
Dynamic Steering Torque (DST) System
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 (e.g. braking on surfaces
with different grip conditions), the ESC system
influences the steering through the DST func -
tion to implement an additional torque contri -
bution 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 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 dependent on the driver’s
sensitivity and overall reaction 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
Some models of this vehicle are equipped with
an All-Wheel Drive (AWD) system, which offers
an optimal drive for countless driving condi
-
tions and road surfaces. The system reduces
tire slipping 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 environ -
mental conditions require better traction, the
vehicle automatically switches to AWD mode.

NOTE:

There may be a brief delay in shifting to
AWD mode after a tire slipping event occurs.
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) System
The ESC system improves the directional
control and stability of the vehicle in various
driving conditions.
The ESC system corrects the vehicle’s under -
steer 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
oversteer or understeer.
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.
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.

Operating Mode
The system may be activated/deactivated via
the radio system. To access the function,
select the following items on the main menu in
sequence:
1. “Driving Assistance”
2. “Blind Spot Alert”
“Blind Spot Alert”, “Visual” Mode
When the system is enabled, the warning light
within the door mirror on the side of the
detected object illuminates.
The visual warning on the mirror will blink if the
driver activates the turn signals, indicating a
lane change.
The warning light will be constant if the driver
stays in the same lane.
“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
Ú
page 268.
Active Blind Spot Assist (ABSA) System — If
Equipped
The ABSA system is to help avoid/limit lateral
collisions with cars coming from adjacent lanes changing the vehicle’s trajectory in order
to try to keep it in the detected lane.
The system warns the driver about the pres
-
ence of other vehicles in the detection area by
illuminating the warning light located within
the door mirror on the side in which the other
vehicle was detected and by means of 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
then “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 radar sensors, located in the
rear fascia/bumper, to detect the presence of
vehicles (cars, trucks, motorbikes, etc.) in the
rear side blind spots of the car.
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 responsibility to steer, brake or
accelerate, especially after the ABSA
system warning or after the steering wheel
torque intervention. The driver is respon
-
sible for ensuring that there are no pedes -
trians, 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 any
time turning the steering wheel in the
opposite direction.

The function of this system can also be tempo-
rarily reduced due to obstructions such as
mud, dirt or ice on the fascia/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 condi -
tions of high reflectivity (e.g. tunnels with
reflective tiles or ice or snow). When the condi -
tions 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, manu -
ally removing the decorative cover trim and
cleaning the radar surface could be required.
Have this operation performed at an autho -
rized dealer.
NOTE:

It is recommended that you do not install
devices, accessories or aerodynamic attach
-
ments in front of the sensor or darken it in any
way, as this can compromise the correct func -
tioning of the system.
Frontal Collision Alarm With Active Braking — If
Equipped
If this function is selected, the brakes are
operated to reduce the speed of the vehicle in
the event of potential frontal impact.
This function applies an additional braking
pressure if the braking pressure applied by the
driver does not suffice to prevent potential
frontal impact.
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 interven -
tion might be unexpected or delayed. The
driver must therefore be very careful, keeping
control of the vehicle to drive in complete
safety.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 manu -
ally through the Information and Entertain -
ment system.
If the driver depresses 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 deacti -
vated when operating in race mode and a
warning message will be displayed on the
instrument cluster.
