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 these 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.

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.
AUXILIARY DRIVING
SYSTEMS
The following auxiliary driving systems are
available in this vehicle:
Forward Collision Warning (FCW)
Tire Pressure Monitoring System (TPMS)
Driver Attention Assist (DAA)
The vehicle may also be fitted with the following
driving assistance systems:
Blind Spot Monitoring (BSM)
Active Blind Spot Assist (ABSA)
Lane Departure Warning (LDW)
Lane Keeping Assist (LKA)
Highway Assist System (HAS)
Traffic Jam Assist (TJA)
Adaptive Cruise Control (ACC)
Intelligent Speed Control (ISC)
Traffic Sign Recognition (TSR)
For the operation of the LDW, LKA, HAS, TJA, ACC,
ISC, or TSR systems, see

Ú
page 81.

NOTE:
When driving on two-way roads where there is no
lane dividing center line (e.g. on unpaved roads),
the use of the Active Blind Spot Assist (ABSA), HAS, TJA, and LKA systems is strongly discour
-
aged as the system could detect the entire road
as single-lane dividing lines.

NOTE:
The driving assistance systems are designed to
aid in driving the car. The driver must always
maintain a sufficient level of attention to the
traffic and road conditions and control the trajec -
tory of the car.
BLIND SPOT MONITORING (BSM)
S
YSTEM — IF EQUIPPED
The BSM system uses two radar sensors, located
in the rear fascia/bumper (one on each side), to
detect the presence of other vehicles in the rear
side blind spots of your vehicle.
Rear Sensor Location
The system warns the driver about the presence
of other vehicles in the detection area by illumi -
nating the BSM Warning Light located within the
door mirror on the side in which the other vehicle
was detected. If equipped, an audible chime will
also be heard to alert the driver (if option is
selected within the radio system). BSM Indicator Light
When the engine is started, the warning light
illuminates briefly to signal the driver that the
system is active.
Sensors
The sensors are activated when any forward gear
is engaged at a speed higher than approximately
6 mph (10 km/h). The sensors are temporarily deactivated when
the vehicle is stationary or the vehicle is in PARK.
The detection area of the system covers approxi -
mately one lane on both sides of the vehicle.
This area begins from the door mirror and
extends for approximately 19 ft (6 m) towards the
rear part of the vehicle.
When the sensors are active, the system
monitors the detection areas on both sides of the
vehicle and warns the driver about the possible
presence of vehicles in these areas.
23_GA_OM_EN_USC_t.book Page 132

133

While driving, the system monitors the detection
zone to check whether it is necessary to send a
signal to the driver on both sides. The system
monitors this detection zone in three different
situations:
When you are being overtaken by a vehicle.
When you are overtaking a vehicle.
When a vehicle approaches from the side.

NOTE:

The system does not alert the driver of the
presence of fixed objects (e.g. safety barriers,
poles, walls, etc.). However, in some circum-
stances, the system may activate in the
presence of these objects. This is normal and
does not indicate a system malfunction.
The system does not alert the driver about the
presence of vehicles coming from the opposite
direction, in the adjacent lanes.
If a trailer is hitched to the car, the system
automatically deactivates.
Rear View
The system detects vehicles coming from the rear
part of your vehicle on both sides and entering the rear detection area with a difference in speed
of less than 25 mph (40 km/h) in relation to your
vehicle.
Overtaking Vehicles

If another vehicle is overtaken slowly, with a
difference in speed of less than 15 mph (25 km/h)
and the vehicle stays in the blind spot for approxi
-
mately 1.5 seconds, the warning light on the door
mirror of the corresponding side illuminates.

If the difference in speed between the two
vehicles is greater than 15 mph (25 km/h), the
warning light does not illuminate

Ú
page 239.
Rear Cross Path Detection (RCP) System
The RCP system assists the driver during reverse
maneuvers in the case of reduced visibility.
The RCP system monitors the rear detection
areas on both sides of the vehicle to detect
objects moving toward the sides of the vehicle,
with a minimum speed between 1 mph (1 km/h)
and 2 mph (3 km/h) and objects moving at a
maximum speed of 21 mph (35 km/h), in areas such as parking lots.
The system activation is signaled to the driver by
an audible warning.

NOTE:

If the sensors are covered by objects or
vehicles, the system may not work as intended.
For the system to operate correctly, the rear
fascia/bumper area where the radar sensors
are located must stay free from snow, ice and
dirt gathered from the road surface.
Do not cover the rear fascia/bumper area
where the radar sensors are located with any
object (e.g. adhesives, bike rack, etc.). 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. “Settings”
2. “Passive Safety”
3. “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.
WARNING!
The Blind Spot Monitoring system is only an
aid to help detect objects in the blind spot
zones. The BSM system is not designed to
detect pedestrians, bicyclists, or animals. Even
if your vehicle is equipped with the BSM
system, always check your vehicle’s mirrors,
glance over your shoulder, and use your turn
signal before changing lanes. Failure to do so
can result in serious injury or death.
WARNING!
Rear Cross Path Detection (RCP) is not a back
up aid system. It is intended to be used to help
a driver detect an oncoming vehicle in a
parking lot situation. Drivers must be careful
when backing up, even when using RCP.
Always check carefully behind your vehicle,
look behind you, and be sure to check for
pedestrians, animals, other vehicles,
obstructions, and blind spots before backing
up. Failure to do so can result in serious injury
or death.

(Continued)
“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.
WARNING!
23_GA_OM_EN_USC_t.book Page 134

135

Rear Sensor Location
While driving, the system monitors the detection
zone in three different situations:
When you are being overtaken by a vehicle;
When you are overtaking a vehicle;
When a vehicle approaches from the side;
to check if it is necessary to intervene in order to
keep the vehicle inside the lane on both sides.

NOTE:
The system does not signal the presence of fixed
objects (e.g. safety barriers, poles, walls, etc.).
However, in some circumstances, the system
may activate in the presence of these objects.
This is normal and does not indicate a system
malfunction.
The system does not warn the driver about the
presence of cars coming from the opposite direc -
tion, in the adjacent lanes.
Activation/Deactivation
The system can be activated/deactivated using
the “Driver Assistance” menu in the radio system.
Select signal type, strength levels and sensitivity.

NOTE:
Vehicles with an active system will display the
following screen, on the radio system.
ABSA Menu Screen
System Intervention
The system intervenes in the following conditions:
the direction indicators have been turned on;
there is a vehicle in the adjacent lane on the
same side of the direction indicator (blind spot
area);
lane lines are not correctly detected;
the driver tries to change lanes unintentionally.
If the system detects the presence of a vehicle in
the rear side blind spots of the car, it applies a
torque on the steering wheel (if it has been set
through the “Settings” menu of the radio system),
in order to warn the driver of the need to keep the
car inside the lane and thus avoid collisions with
other vehicles.
The application of torque and vibration is
however only available with car speed between
37 mph (60 km/h) and 110 mph (180 km/h). The application of torque, as well as of the
vibration, is suppressed/inhibited if:
The torque given by the driver of the steering
wheel is high
Lateral acceleration is high
The trailer is not connected to the correct
control module
At least one hand is not detected on the
steering wheel for longer than a specific time
The turn signal is turned off

NOTE:
The steering wheel torque is not applied if the
system is unable to detect a lane and if the direc
-
tion indicator for the appropriate side has not
been switched on.
The steering wheel detects the presence of the
driver’s hands by a capacitive sensor installed in
the steering wheel and by the applied torque
measured on the steering column.
System Availability
Aggressive driving of the car, or driving on the
median lines, will prevent the correct operation of
the system.
In case of intervention of the stability and braking
systems (FCW, ESC, ABS) they will prevent the
system from operating.
Lane change will disable the system for a certain
period of time.
The road must also comply with some specific
characteristics, such as:
Maximum/minimum lane width.
Clearly identified and defined double yellow
lines and, for a limited period of time, a lane
with a single demarcation line.
23_GA_OM_EN_USC_t.book Page 135

SAFETY

136

NOTE:
In some cases, for a limited period of time, the
system may be activated by a lane with a single
median line.
In cases of good road surface conditions, the
system could correctly recognize other types of
valid lane markings (e.g. road edges, sidewalks,
etc.).
Hand Presence On The Steering Wheel Detection
The system is able to detect the presence of the
driver’s hands on the steering wheel.
When the system does not detect the presence of
hands on the steering wheel for zero to six
seconds, the following screen will be displayed on
the instrument cluster display. No acoustic
warning will be emitted in this case.Hand Presence On The Steering Wheel Not Detected Display (Up To Six Seconds) When the system does not detect the presence of
hands on the steering wheel from 6 to 15 sec-
onds, the following screen will be displayed on
the instrument cluster display. A short acoustic
signal will sound if hands are not detected on the
steering wheel for 6 to 12 seconds. A continuous
signal will sound if hands are not detected on the
steering wheel for 12 to 15 seconds.
Hand Presence On The Steering Wheel Not Detected Display (6 To 15 Seconds)
After 15 seconds with the hands removed from
the steering wheel, the LKA system will be
deactivated and a dedicated message will be
shown on the instrument cluster display. A short
acoustic signal will sound in this case.
In any of the previous situations where the hands
are removed from the steering wheel for more
than six seconds, it is necessary to reposition the
hands on the steering wheel. Changing The System Sensitivity
The system's sensitivity can be set through the
radio system in the “Driver Assistance” menu and
then selecting “Comfort”. Sensitivity “High” or
“Low” can be selected.
Rear Cross Path Detection (RCP) System
The Rear Cross Path Detection (RCP) system
assists the driver during reverse maneuvers in
the case of reduced visibility.

When the ABSA system is active, the RCP system
monitors the rear detection areas on both sides of
the vehicle to detect objects moving towards the
sides of the vehicle at a minimum speed between
0.6 mph and 2 mph (1 km/h and 3 km/h) to
objects moving at a maximum speed of 22 mph
(35 km/h).

These are generally occurrences that happen in
parking areas.
The system activation is signaled to the driver by
means of a visual and audible warning.

NOTE:
If the sensors are covered by objects or vehicles,
the system may not work as intended.
Changing The System Sensitivity
To change the sensitivity and the strength of the
torque intervention on the steering wheel, refer to
the Information and Entertainment System
Owner’s Manual Supplement.

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 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 conditions of
high reflectivity (e.g. tunnels with reflective tiles
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 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 Equipped
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

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.
Driving In Roundabouts Vehicles With Small Dimensions And/Or Not
Aligned In The Driving Lane
The system cannot detect vehicles in front of you
but outside the range of the radar sensor and
may therefore not react in the presence of small
vehicles, such as bicycles or motorcycles.
Driving Near Small Vehicles
Lane Change By Other Vehicles
Vehicles suddenly changing lanes to enter the
same lane as your vehicle within the operating
range of the radar sensor, may cause the system
to intervene. Other Vehicles Changing Lanes
Vehicles Traveling At Right Angles To The Vehicle
The system may temporarily react to a vehicle
that is passing through the radar sensor’s
operating range at right angles.
