Indications On The Display
The HAS system status can always be viewed
in the instrument cluster display.
The system status is indicated by the color of
the symbol on the display.
The HAS system uses sensors in the steering
wheel to detect if the driver’s hands are on it.
If the driver’s hands are not on the steering
wheel, a series of warnings will appear in the
instrument cluster display to alert the driver to
reposition their hands on the steering wheel.
An acoustic signal will also sound. After a
period of time, the HAS system will disable if
the driver’s hands do not return to the steering
wheel.
After a period of time, the HAS system will
disable if the driver has not repositioned their
hands on the steering wheel.
When the system does not detect hands on
the steering wheel, it will warn the driver by
displaying a dedicated screen on the instru -
ment cluster display.

TRAFFIC JAM ASSIST (TJA)
SYSTEM — IF EQUIPPED
The Traffic Jam Assist (TJA) system can be acti -
vated on all road types. The system uses a
camera 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 automati -
cally 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.
To Activate/Deactivate
To activate the system, push the button on the
left side of the steering wheel.
To deactivate the system, push the button
again.

Turning Lane Departure Warning On Or Off
The system is activated/deactivated by
pushing the button located on the end of the
multifunction lever, or through the “Driver
Assistance” widget though the radio system.Lane Departure Warning System Activation/ Deactivation Button

NOTE:

The Lane Departure Warning system will retain
the last system state on or off from the last
ignition cycle when the ignition is placed in the
ON/RUN position.
Activation Conditions
Once turned on, the system becomes active
only if the following conditions are met:
The vehicle speed is equal to or above
37 mph (60 km/h) (the system is deacti -
vated at speeds equal to or greater than
110 mph (180 km/h)).
The lane markings are visible at least on
one side.
There are suitable visibility conditions.
The road is straight or with wide radius
bends.
A suitable distance is kept from the vehicle
in front.
The turn signal is not active.
Lane Departure Warning Message
The Lane Departure Warning system will indi -
cate the current lane drift condition through
the instrument cluster display.
When the system is on and the lane markings
have not been detected, the display shows two
grey lane lines.
Lane Markings Not Detected Left Lane Departure — Only Left Lane
Detected

When the system is active and only, for example,
the left lane marking has been detected, the
detected lane illuminates in white on the display;
the system is ready to provide visual warnings on
the display in the event of unintentional exiting of
the lane (turn signal not activated) to the left.

Left Lane Marking Detected
When the system detects that the vehicle has
approached the lane marking and is about to
pass it, the left line on the display illuminates
in yellow.
Left Lane Marking Approached
21_GA_OM_EN_USC_t.book Page 129

STARTING AND OPERATING

130

The system operates in the same way, but
mirrored, in the event of exiting the right lane
when only the right lane marking has been
detected.
Left Lane Departure — Both Lanes Detected
When the system is active, both lane lines on
the display illuminate in white to indicate that
both of the lane markings have been detected.
When lane markings are detected, the system
is ready to provide indications in case the
driver unintentionally leaves the lane (turn
signal not activated).
As the Lane Departure Warning system
detects the lane markings while the vehicle is
in motion, it will adjust the display accordingly
(from white to yellow and vice versa, and
increase their thickness).
If a lane line is crossed, the driver is alerted by
an audible signal as well as the visual indica-
tion in the instrument cluster. The signal is
emitted through the speakers on the side of
the lane marking which is being crossed (e.g.
if the vehicle is exceeding the left line of the
lane, the audible signal will come from the
speakers on the left of the vehicle).
Limited Operation Warning
If a message appears on the display, a condi -
tion limiting the Lane Departure Warning
system operation may have occurred. This
could be an obstruction of the camera view, or
a fault in the system. If an obstruction is detected, clean the area of
the windshield by the interior rearview mirror.
Although the vehicle can still be driven in
normal conditions, the system may not func
-
tion properly.
When the conditions limiting the system are
corrected, it will go back to normal operation.
Should a fault persist, contact an authorized
dealer.
System Failure Warning
If the system turns off and the warning light
appears on the display, it means that there is
a system fault.
In this case, it is still possible to drive the
vehicle, but you are advised to contact an
authorized dealer as soon as possible.
Changing Lane Departure Warning Status
The system's sensitivity can be set through the
radio system. Sensitivity “High” or “Low” can
be selected.
To access the function, from the main menu
select the following in order:
1. “Settings”
2. “Driver Assistance”
3. “Lane Departure Warning”
4. “Sensitivity”
LANE KEEPING ASSIST (LKA)
SYSTEM — IF EQUIPPED
The Lane Keeping Assist (LKA) system uses a
camera located on the windshield to detect
the lane markings and calculate the position
of the vehicle within such markings, in order to
make sure that the vehicle remains inside the
lane. This is an active system that will apply
torque to the steering wheel if it senses that
the vehicle is drifting out of the lane.

When one or both lane markings are detected
and the vehicle passes over one without a turn
signal being applied, the system will apply torque
to the steering wheel and a visual signal will be
displayed in the instrument cluster display. An
audible signal may also sound.
If the vehicle continues to go beyond the lane line
without any driver intervention, the surpassed
lane line (left or right) will light up on the instru -
ment cluster display to urge the driver to bring
the vehicle back inside the lane limits.
