TRAFFIC JAM ASSIST (TJA)
SYSTEM — IF EQUIPPED
The Traffic Jam Assist (TJA) system can be
activated on all road types. The system uses a
camera and radar sensors located on the front
fascia/bumper to detect lane markings and keep
the vehicle in the center of the lane.
When the system is unable to detect lane
markings, it will still operate using surrounding
traffic. This can occur in congested traffic
scenarios, when the vehicles ahead or
surrounding obstruct the visibility of the lane
markings. When the speed is below 12 mph
(20 km/h), the system can use a lock-on strategy
that allows the vehicle to automatically follow the
vehicle ahead.
The TJA system combines Adaptive Cruise Control
(ACC) functions with Lane Departure Warning
functions to maintain vehicle speed and steering
wheel behavior.

NOTE:
Do not use the TJA system while driving in urban
areas.

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

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

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.
