NOTE:

When TJA is turned off, the symbol in the
instrument cluster display will turn red, and
then grey.
A sensor in the steering wheel detects whether
the driver’s hands are placed on the steering
wheel.
When the automatic suspension conditions are
over, the TJA system will be automatically
reactivated.
OPERATION
The TJA system can only operate when the
driver’s hands are on the steering wheel.
If the system detects that the driver’s hands have
been removed from the steering wheel, a
message will appear in the instrument cluster
display to alert the driver to place their hands
back on the wheel.

NOTE:

If the vehicle begins to cross the lane
boundary, the steering wheel will vibrate and a
dedicated screen will appear in the instrument
cluster display.
The TJA system may take up to five seconds to
become active once all conditions are met.
The following conditions must be met in order to
activate the system:
The TJA system must be enabled
The Adaptive Cruise Control (ACC) system must
be turned on
The right and left lane boundaries must be
recognized by the system
The vehicle must be traveling at a speed
between 0 and 37 mph (0 and 60 km/h)

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
No passing zones
Signs indicating the end of the situations
indicated aboveIf 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/h 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:
The TSR system will reset to the default setting
when the vehicle is restarted.

NOTE:

By selecting “Blinking”, the driver can activate
a warning to display when the speed exceeds
the limit indicated by the TSR System. The
speed road sign on the instrument 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 indicating
the end of the speed limit or a “Road Sign Not
Detected” message may appear in this zone.
After a predetermined distance, the previously
displayed road sign changes color to inform
the driver that the speed limit provided may no
longer be valid.
If the camera does not detect valid speed
limits, the navigation system may suggest
unregulated speed limits on the instrument
panel display.
WARNING!
To prevent serious injury or death:
Always remain alert and be ready to take
control of the car 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.
The TJA system should only be used as a
driving aid. The driver must always pay
attention to their surroundings when the
system is operating and be ready to take
control of the vehicle at any time.
Do not place any objects on the steering
wheel (e.g. steering wheel covers) that could
interfere with the hand detection sensor on
the steering wheel.

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 adjustment, 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 instrument
panel display.

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.
ACCEPTANCE/REJECTION OF THE
S
UGGESTED 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
indicating 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 telltale.
To reject the proposed speed, move the RES/SET
switch up or down in the direction opposite 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 deactivated,
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).
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.

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 presence of any
obstacles and warn the driver through an
acoustic signal and visual indications, which will
be displayed on the instrument cluster display.Front Sensor Location
Rear 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. Driver Assistance
2. ParkSense
3. Mode
4. 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.
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.
23_GA_OM_EN_USC_t.book Page 116

117

If several obstacles are detected simultaneously
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 obsta-
cles, the closest obstacle is considered. An inter -
mittent signal will sound if the obstacles 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 approximately five
seconds. The light will then stay on constantly.

NOTE:
When the ignition is placed in the ON/RUN posi
-
tion, the ParkSense system keeps the last state
when the engine was stopped (activated or deac -
tivated) 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 70.
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 fascias/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
P
RECAUTIONS

NOTE:
Some conditions may influence the performance
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 interference,
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 suspension), 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
windshield 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 activated
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, or
formation of ice layers on the windshield.
Camera operation may also be compromised
by the presence of dust, condensation, 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 curvature), 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!
