TRAFFIC SIGN RECOGNITION
(TSR) SYSTEM — IF EQUIPPED
The Traffic Sign Recognition (TSR) system
uses a camera mounted on the windshield to
detect recognizable road signs such as:
Speed limits
Signs indicating the end of the situations
indicated above
If the camera does not detect valid speed
limits, the radio system navigation system may
suggest unregulated speed limits.
The system always checks the traffic signs
indicating the current speed limit signs. The
system is able to recognize and display up to
two different road signs in the instrument
cluster display.
Depending on the unit of measurement (km or
mph) set through the “Unit of Measurement”
menu in the radio system, the TSR system will
automatically show the indication of the road
sign in the unit of measurements selected in
the instrument cluster display.
To Activate/Deactivate
The TSR System can be activated/deactivated
in the radio system in the “Driver Assistance”
menu. The system activation is signaled by
road signs shown on the instrument cluster
display.
NOTE:

By selecting “Blinking”, the driver can acti
-
vate a warning to display when the speed
exceeds the limit indicated by the TSR
System. The speed road sign on the instru -
ment cluster display will blink until the
vehicle speed drops below the displayed
limit.
Selecting “Offset” will set the speed at
which “Blinking” is activated up to a
maximum of 6 mph (10 km/h) above the
limit detected by the system.
If no speed limit signs are found, the system
will revert to the speed limit signs that are
stored in the NAV system.
Indications On The Display
The system status can always be viewed
through the instrument cluster display.
The instrument cluster display shows only the
speed limit indications and consists of the
following steps:
The new speed limit recognized by the
system, which is indicated by means of a
predetermined color. The road sign indi -
cating the end of the speed limit or a “Road
Sign Not Detected” message may appear in
this zone.
After a predetermined distance, the previ -
ously displayed road sign changes color to
inform the driver that the speed limit
provided may no longer be valid. 1 — Traffic Sign Recognized
WARNING!
To prevent serious injury or death:
Always remain alert and be ready to take
control of the vehicle in the event that the
TJA system disables.
Always keep your hands on the steering
wheel when the TJA system is activated.

Maintain a safe distance from other vehicles
and pay attention to traffic conditions.

CAUTION!
Functionality may be limited or the system
may not work if the sensor is obstructed.

The system may have limited operation or
not work at all in weather conditions such as
heavy rain, hail, thick fog, and low tempera
-
tures. Strong light contrasts can influence
the recognition capability of the sensor.

INTELLIGENT SPEED CONTROL
(ISC) SYSTEM — IF EQUIPPED
The Intelligent Speed Control (ISC) system is
always paired with the Adaptive Cruise Control
(ACC) system. The ISC system suggests an
automatic speed adjustment to the driver
based on the speed limit for the road being
traveled. The driver can decide whether to
accept or reject the automatic speed adjust-
ment, using the switch on the steering wheel.
If the speed limit is exceeded according to the
road signs or traffic conditions, a dedicated
graphic message is displayed on the instru -
ment panel display. RES/SET Switch
To Activate/Deactivate
To Activate
The system can be activated in the radio
system within the “Driver Assistance” menu.
The symbol illuminates in the instrument
cluster display when the system is active.
1 — ISC System Active To Deactivate
The system is deactivated under the following
conditions:
When the Traffic Sign Recognition (TSR)
system is deactivated
When the Adaptive Cruise Control (ACC)
system is deactivated

NOTE:

Selecting “Speed Offset” allows the driver to
set the speed up to a maximum of 6 mph
(10 km/h) above or below the suggested
speed set by the ISC system. In this instance,
the road sign information shown in the instru -
ment cluster display will continue to be
detected by the TSR system.
Indications On The Display
The system status is indicated by a white or
green icon in the instrument cluster display
(similar to the Adaptive Cruise Control (ACC)
device) to the left of the road sign indications
provided by the Traffic Sign Recognition (TSR)
system.

The area surrounding the sensor must not
be covered with stickers or any other object.

Do not tamper or perform any operations
in the area of the windshield glass directly
surrounding the sensor.
Clean foreign matters such as bird drop -
pings, insects, snow or ice on the wind -
shield. Use specific detergents and clean
cloths to avoid scratching the windshield.
CAUTION! (Continued)

Acceptance/Rejection Of The Suggested
Speed
The system can be activated if the driver has
activated the following systems beforehand:
Adaptive Cruise Control (ACC)
Traffic Sign Recognition (TSR)
When these systems are active, a telltale will
display in the instrument cluster display indi -
cating the suggested speed provided by the
TSR system. The driver has the option to
accept or reject this using the RES/SET switch
on the steering wheel.
To accept the proposed speed and adjust the
speed set by ACC, move the RES/SET switch
up or down in the direction indicated in the tell -
tale.
To reject the proposed speed, move the RES/
SET switch up or down in the direction oppo -
site of the arrow in the telltale. The ACC system
will continue to regulate to the previously set
speed.
If the speed set by the ACC system is the same
as the speed detected by the TSR system, the
speed limit indicator on the instrument cluster
display will be highlighted with a green circle. 1 — Suggested Speed Higher Than
Current Speed
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).

STARTING AND OPERATING

126

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.
Front Sensor LocationRear Sensor Location
ParkSense Display
The driver can select the type of warning they
would like to be displayed through the radio
system. To access the function on the main
menu, select in the following order:
1. “Settings”
2. “Driver Assistance”
3. “ParkSense”
4. “Mode”
5. “Sound and Display”
Visual Indications
The system indicates the presence of an
obstacle by displaying a single red arc in the
detected area, in relation to the distance of
the object and the position of the vehicle.
If the obstacle is detected in the front or rear
central area, a single red arc will be displayed
as the obstacle approaches, first constant,
then flashing, in addition to an acoustic signal.
If the obstacle is detected in the front or rear
left and/or right area, a single red flashing arc
will be shown in the corresponding area on the
display and the system will emit an acoustic
signal, either at frequent intervals or
constantly.
In general, the vehicle is closer to the obstacle
when a single red flashing arc is shown on the
display and the acoustic signal becomes
continuous.
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.
21_GA_OM_EN_USC_t.book Page 126

127

If several obstacles are detected simultane-
ously in the front and rear area, the display will
show all of them, regardless of the area in
which they were detected.
It is not possible to exit from the display screen
while the vehicle is in REVERSE.
Acoustic Signal
In the presence of an obstacle at the front or
the rear of the vehicle, an acoustic signal with
variable frequency will sound:
The acoustic signal increases in frequency
as the distance between the vehicle and the
obstacle decreases.
The acoustic signal becomes continuous
when the distance between the vehicle and
the obstacle is less than 11 inches (30 cm),
and stops if the distance increases.
The acoustic signal is constant if the
distance between the vehicle and the
obstacle is unchanged.

NOTE:

If the sensors detect several front and rear
obstacles, the closest obstacle is considered.
An intermittent signal will sound if the obsta -
cles are at the same distance (front and rear).
When the system emits an acoustic signal, the
volume of the radio system, if activated, is
automatically lowered.
An acoustic signal will not sound if the vehicle
is in PARK.
Enabling And Disabling ParkSense

For vehicles only equipped with rear sensors, to
turn the system off, push the ParkSense button
located to the left of the headlight switch. The
indicator light within the button will illuminate
when the system is turned off. Pushing the
button a second time will turn the system back
on, and the indicator light will turn off.

ParkSense On/Off Switch
For vehicles equipped with front and rear
sensors, to turn the front parking sensors off,
push the ParkSense button located to the left
of the headlight switch. The indicator light
within the switch will illuminate when the
system is turned off. Pushing the button a
second time will turn the front sensors back
on, and the indicator light will turn off.

NOTE:

Deactivation of both the front and rear parking
sensors can only be done through the radio
system. The indicator light within the ParkSense
system switch will also be on in case of system
failure. If the switch is pushed with a system
failure, the indicator light will flash for approx
-
imately five seconds. The light will then stay on
constantly.

NOTE:

When the ignition is placed in the ON/RUN
position, the ParkSense system keeps the last
state when the engine was stopped (activated
or deactivated) in its memory.
ParkSense Warning Display
Parking sensor faults, if any, will be indicated
when REVERSE is engaged by a message on
the instrument cluster display
Ú
page 73.
In case of system failure, a dedicated
message appears on the instrument cluster
for about five seconds.

Cleaning The Front Or Rear Sensors : If the
display shows a message requiring the
sensors to be cleaned, make sure that the
outer surface and the underside of the front
and rear bumpers are free of debris (e.g.
snow, mud, ice, etc.). Once these areas are
clear, place the ignition in the OFF position,
then return it to ON/RUN. If the message is
still displayed, contact an authorized dealer.
Audio System Not Available : If the display
shows a message that the audio system is not
available, it means that the acoustic signal will
be emitted by the instrument panel, and not
through the vehicle’s speakers.

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.
LANE DEPARTURE WARNING
(LDW) SYSTEM — IF EQUIPPED
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 audible 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 to
not 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 an 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 your 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

142

Active Torque Vectoring (ATV) — If Equipped
The dynamic drive control is used to optimize
and balance the drive torque between the
wheels of the same axles. The ATV system
improves the grip in turns, sending more drive
torque to the external wheel.
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)
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 contribu-
tion 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 — If
Equipped
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
the slipping of the tires to a minimum, auto -
matically 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 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 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.
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.
