Electronic Cruise Control The electronic Cruise Control (CC)
enables the driver to maintain the
desired vehicle speed without pressing
the accelerator pedal, reducing driving
fatigue on highways, especially long
trips, as the set speed is automatically
maintained. A firm press on the
accelerator pedal or the braking pedal
will temporarily deactivate the cruise
control function.
CAUTION!
The device can only be switched on at
speeds exceeding 18 mph (30 km/h)
and it switches off automatically when
the brake pedal or the accelerator
pedal is pressed.
WARNING!
The Cruise Control function must only
be activated when traffic and the
route permit a constant speed to be
maintained safely for a sufficiently
long distance. Controls The electronic Cruise Control controls
are located on the left side of the
steering wheel.
Control configuration depends on
which driver assist systems are installed
to the vehicle.
In the standard configuration there is
a specific button to enable and disable
the CC.
In the optional configuration, there is
no specific button to enable and
disable the CC, since the driver uses
the ACC control buttons. Control buttons have the following
functions:
Standard Configuration
ON/OFF button to
engage/disengage CC
system.
Optional Configuration
Press ACC Gap button and
hold it down for 2 seconds
to enable the CC system.
Press ACC button to disable
the CC system.Standard Configuration Optional ConfigurationDriving

could cause an incorrect assessment
of the required safety distance.
It is recommended to disable the ACC
system in the following instances:
• When driving in the fog, heavy rain,
heavy snow, slush, heavy traffic and
similar complex situations such as
highway construction zones.
• When entering a junction lane or a
slip road to leave the highway; when
driving on narrow, icy, snowy,
slippery roads, or on steep uphill and
downhill roads.
• When circumstances do not allow to
drive safely at constant speed.
Displayed information Adaptive Cruise Control (ACC)
condition, as well as the LKA and HAS
status, is displayed on instrument
cluster after selecting “Driver Assist”
menu (see paragraph “TFT Display:
Menus and Settings" under
“Instrument Cluster” in section
“Dashboard Instruments and
Controls”).
Displayed information depends on
system status: ready, set, temporarily
cancelled or override.
Apart from the image at the center of
the display, CC, ACC, LKA and HAS
systems status is represented by icons at the top left and right. These icons
remain displayed even when exiting
the "Driver Assist" screen.
The vehicle(s) and horizontal bars
represent the ACC status as ready
(white) or with sensed vehicle ahead
(green); the white, grey or yellow lines
represent the LKA and HAS systems.
The ACC screen can be displayed any
time driver changes system status or
settings. After 5 seconds of ACC
inactivity, the display goes back to last
screen.
ACC Controls and Activation

Forward Collision Warning
– FCW The Forward Collision Warning (FCW)
system with braking action uses the
same parts already described for
Adaptive Cruise Control (ACC) for
sensing vehicle ahead (hereinafter
“target vehicle”) as well as part of the
warnings/messages on system
condition and activation status.
Full performance can be reached only
when both the sensing parts have
detected a vehicle or, if the car is
equipped with Pedestrian Emergency
Braking (PEB) system, also a
pedestrian. The difference between full and
reduced performance is not visible for
the driver.
Pedestrian Emergency Braking
(PEB) System (if equipped) The Pedestrian Emergency Braking
(PEB) is a sub-system of FCW and it
provides the driver with audible
warnings, visual warnings on the
instrument cluster display, and may
apply automatic braking when it
detect a potential frontal collision with
a pedestrian.
WARNING!
Pedestrian Emergency Braking (PEB) is
not intended to avoid a collision on its
own, nor can PEB detect every type of
potential collision with pedestrian.
The driver has the responsibility to avoid a collision by controlling the
vehicle via braking and steering.
Failure to follow this warning could
lead to serious injury or death.
FCW Operation The FCW provides audible and visual
warnings when a potential collision is
detected. Brake jerk and limited
braking may also be applied
depending on the specific scenario.
FCW monitors the information from
the forward looking radar sensor as
well as the Electronic Brake Controller
(EBC), to calculate the probability of a
forward collision. When the system
determines that a forward collision is
probable, the driver will be provided
with audible and visual warnings and
may provide a warning brake
actuation. If the driver does not take
actuation based upon these
progressive warnings, then the system
will provide a limited level of active
braking to help slow down the vehicle
and mitigate the potential forward
collision. If the driver reacts to the
warnings by braking and the system
determines that the driver intends to
avoid the collision by braking but has
not applied sufficient brake force, theDriving
5
258

system will compensate and provide
additional brake force as required.
When the system determines a
collision with the vehicle in front of
you is no longer probable, the
warning messages will be deactivated.
NOTE:
• Bad weather conditions, like heavy
rain, snow, etc., can lead to reduced
system performance. Under these
conditions relevant objects will not
be detected or detected late by the
system.
• FCW is designed to react in specific
situations in typical traffic scenarios
with objects in the same lane driving
in the same direction, but under
certain conditions it can also react
on stationary objects in the same
lane. It is not designed to react to
oncoming traffic or crossing traffic.
• The FCW alerts may be triggered to
objects other than vehicles such as
guard rails or sign posts based on
the course prediction. This is
expected and is a part of normal
FCW activation and functionality.
• It is unsafe to test the FCW system.
To prevent such misuse of the
system, after four Active Braking
events within a key cycle, the Active
Braking portion of FCW will be deactivated until the next key cycle.
The limit of four events applies to
the brake actuation too.
• FCW will automatically deactivated
when
(ESC OFF) button is pressed
(LED light up).
WARNING!
• Forward Collision Warning (FCW) is
not intended to avoid a collision on
its own, nor can FCW detect every
type of potential collision. The
driver has the responsibility to avoid
a collision by controlling the vehicle
via braking and steering. Failure to
follow this warning could lead to
serious injury or death. The driver is
always in charge to safely drive and
to avoid critical situations, and not
rely on the support of the FCW
system. Driver has to keep in mind
that the system and therefore its
intervention is always subject to the
prevailing physical limits.
• Forward Collision Warning (FCW) is
not intended either to warn or to
apply any brake aid/brake
intervention in case of collisions
with pedestrians (if not equipped with PEB sub-system), bicycles and
not licensable vehicles in general.
Speed Range of Use Speed mph (km/h)
Minimum 0 (0)
Engaged/activated 1.12 (1.8)
Maximum 155 (250)
When the speed is outside the
specified limits, the system
automatically disables without turning
on the corresponding warning light
on the instrument cluster.
FCW Status The driver can adjust FCW sensitivity
or enable/disable the brake actuation
with the other emergency brakings by
touching "Controls" soft-key on MTC+
display. The current setting is indicated
beside to the "Forward Collision
Warning" soft-key. If you want to
change the setting, touch the soft-key
on the side to enter FCW page.Driving

providing limited autonomous braking
or additional brake support if the
driver is not braking adequately in the
event of a potential frontal collision.
In this state the system disables the
brake jerk.
Limited Operation and Service
Warning The messages indicating on display the
limited functionality or service at an
Authorized Maserati Dealer required
are the same as for the ACC system.
For further details, refer to “Adaptive
Cruise Control – ACC” in this section.
NOTE:
• The adjustment of the sensor could
be affected by strong shocks or light
collisions. This could affect the
system by reducing the systems
performance or could increase the
false positive rate. The adjustment of
the radar system has to be proved or
a new adjustment has to be
performed by an Authorized
Maserati Dealer .
• The radar system requires specific
feature to detect objects. The
detection could be disturbed/
reduced by environment influences,
for example by electrical field or the
object itself. Object with small radar reflection properties could not be
detected or detected late.
Radar Device - Regulatory
Information The “Regulatory Information” for all
the radio frequency and radar devices
can be consulted by accessing the
“Services” section on the website
www.maserati.com.
Lane Keeping Assist - LKA
(optional, with ACC only) This system was designed especially
for highway or freeway driving, to
reduce the risk that the vehicle, under
particular circumstances, accidentally
departs from the lane in use. When
this happens, graphic instructions on
instrument cluster display together
with steering torque application and
steering wheel vibration (depending
on the distance to the line) warn the
driver that the vehicle is going out of
the lane initiates a steering maneuver
to try to prevent the lane exit.
To detect lane lines, the system uses
the forward-facing camera behind the
rear-view mirror, which is the same
one used also by the lighting system
to manage the automatic high beams.
The logic core is in the front radar.
LKA system remembers the condition
it was in before turning off the
vehicle.
Refer to “MTC+ "Controls" Screen” in
section “Dashboard Instruments and
Controls” for further information.Driving

261

NOTE:
In case of wet road or raining
conditions the function could be
disabled by the system in order to
minimize the risks.
Speed Range of Use Speed mph (km/h)
Minimum 37 (60)
Engaged/activated 37 (60)
Maximum 112 (180)
Customized Settings LKA is configurable by the driver in
order to maximize its efficiency based
on the driver driving style and the
expectation of the system, reducing at
the same time the possible
invasiveness.
Entering "Controls" page on MTC+
display the driver can see the current
setting beside the "Lane Keeping
Assist" soft-key.
Touching “Lane Keeping Assist”
soft-key can disable or enable the
system. Touching the soft-key on the side the
driver can change the setting.
Driver warnings can be only "Visual"
or "Visual & Haptic" (default mode).
System response can be set to "Early",
"Medium" (default mode) or "Late".
System reaction force can be set to
"Low", "Medium" (default mode) or
"High".
Meanings of Settings
• "Visual" only: the system will not
request any steering torque/vibration to correct the car trajectory. The
system will only show on the TFT
display when the vehicle is passing
the lane.
• "Visual & Haptic": the system will
apply steering torque when lane
departure is detected while showing
at the same time the proper cluster
indication, adding to this steering
vibration when the departure is very
imminent.
When "Visual & Haptic" is selected and
LKA is enabled then the following
menu will be used by the system.
• "LKA Sensitivity": it tunes the
distance to the lane boundary where
the system will start to apply steering
torque.
• "LKA Strength": it tunes the steering
torque value to have a stronger or
weaker directional correction/
deviation.
WARNING!
In rare cases, Lane Keeping Assist
(LKA) may make an inappropriate
steering torque application. LKA may
be interrupted at any time counter
steering. Lack of attention may lead to
serious injury or death.Driving

System Availability The ADAS systems (LKA, CC, ACC, FCW
and HAS) help the driver while
driving. These systems can be set and
monitored simultaneously on the
display, after opening “Driver Assist”
menu (see paragraph “TFT Display:
Menus and Settings” under
“Instrument Cluster” in section
“Dashboard Instruments and
Controls”).
LKA is designed for an attentive
driver; therefore the system is
available only when his/her hands are
on the steering wheel or with hands
off for only a limited amount of time.
When the system is enabled it will
trigger cluster warning in case at least
one hand is not detected on the
steering wheel.
The torque application as well as the
vibration are suppressed/inhibited in
case of: high driver torque in the
steering wheel, high lateral
acceleration, hands not on the
steering wheel detected for more than
a certain time.
High dynamic driving behaviors,
driving on the lane boundary, or
driving off course will prevent the
function from working. FCW braking
and stability system interventions (ESC, ABS) will also prevent the system from
operating. Changing lanes results in
system inhibition for a certain time. In
addition, the driver must respect some
road characteristics such as
minimum-maximum width, lanes
clearly defined by two lane
boundaries and, only in limited cases
and for a limited time, at least one
lane boundary.
NOTE:
• In case of wet road or raining
conditions the function could be
disabled by the system in order to
minimize the risks.
• With lane boundaries it is mainly
referred to painted lines,
nevertheless the system in good
conditions might properly recognize
as valid lane boundaries also other
types (for example road edges,
curbs, etc..).
Being this function used to prevent
unintentional lane change/lane drift,
it will be temporary suppressed/
inhibited by a turn indicator
activation, therefore, graphic warning,
steering torque application and
vibration will be terminated. In this
condition in case of a vehicle detected
by the Blind Spot Assist (BSA) system in the covered area on the proper
side, there can be the transition from
LKA to Active Blind Spot Assist (ABSA)
(if this latter is on and properly
configured).
Function Description and
Operating Mode The intent of the function is to
prevent the lane departure by
warning the driver through indication
on the cluster and, if set, applying
steering torque and vibration.
Whenever the system is enabled there
will be graphic on the dedicated
screen in the driver assist page and for
the others it will be available in the
left top corner of the cluster screen.
The graphic which intent is to
represent at the glance the system
knowledge of the lane in front of the
car, the system suppression status and
warning.
For this reason, a simple colour code
has been adopted for each line (of the
two presented):
• Both grey lines means system is
enabled, not able to operate
(suppression condition present or
lane detection system not able to
properly estimate the lane);Driving
5
263

• Left/right grey line: the lane
detection system is not able to detect
that specific lane boundary;
• Yellow line: there is a steering torque
intervention in progress that tries to
prevent a departure on that side, in
this situation the warning should
increase the driver attention
requiring him/her to properly handle
the situation;
• Yellow flashing line: the graphic is
shown whenever the system detects
a very imminent lane departure;
torque and steering vibration can be
added to this warning if configured
by the customer.
The white lines (one or both) indicates
that the corresponding lane boundary
is detected and the system is capable
to intervene on it.
An example of these screens can be
found in the following figures:
A: with only LKA system activated,
steering torque in progress to
correct the trajectory towards the
lane center; B: with LKA and ACC systems
activated, car is crossing the lane
boundary, steering torque and
vibration if configured are in
progress when this graphic is
shown.
The icons that represent the status of
the ADAS systems remain displayed
even when you exit the "Driver Assist"
screen.
System Limitations Because of physical limits, in order to
properly operate, the system needs
good visibility (it might not work or
not properly operate in case of heavyDriver Assist Page Non-Driver Assist PageDriving
5
264

rain, snow, wet roads, fog, direct sun
on the camera, etc.).
NOTE:
• The presence of the hands on the
steering wheel is detected by a logic
combination of a capacitive sensor
installed in the steering wheel and
the measured applied torque at the
steering column. This leads to a
more robust hands detection when
hands are actually on the steering
wheel (at least one).
• The sensors are not able to detect
the presence of the hands on the
steering wheel areas covered in
wood, plastic bezels or carbon
inserts (where present).
Sharp turns, slopes and change in
slopes, poor lane boundaries, as well
as construction areas and all the
scenario described in this paragraph
may challenge the system, therefore
be always ready to prevent any
unexpected behaviour of the car.
Damaged front bumper, windshield
replaced without proper technical
intervention may also lead to system
malfunction or system unavailability.
Other conditions such as fault, but not
explicitly indicated here may also prevent/interrupt the system
intervention.
WARNING!
If the driver fails to adapt his/her
driving style, Lane Keeping Assist
(LKA) can neither reduce the risk of an
accident nor override the laws of
physics. It cannot take into account
road, weather or traffic conditions.
Active LKA is only an aid. Driver is
always responsible for the distance to
the vehicle in front, for vehicle speed,
for braking in good time and for
staying in lane.
System in Fault When the LKA cannot properly
operate due to a fault of its
components or because the
windshield in front of the forward
facing camera is dirty, the amber light
and/or the corresponding message will
be displayed. If message suggestion does not allow
fixing the fault, do not use the system
and have the vehicle inspected at an
Authorized Maserati Dealer .

Active Blind Spot Assist -
ABSA (optional, with ACC
only) ABSA system is only available on
vehicles equipped with ACC system
and represents an addition to the BSA
previously described (see chapter
"Blind Spot Assist - BSA" of this
section).
ABSA adds to the BSA the possibility in
certain circumstances to avoid and or
mitigate side collisions with vehicles
proceeding in the adjacent lanes by
changing the car's direction in order
to try to keep it inside the
detected/estimated lane. A steering
wheel vibration is used as further
feedback to warn the driver that the
lane change is not safe.
The main logic core is the front radar,
whereas the sense inputs are the
radars on the rear bumper fascia used
for sensing the presence of vehicle in
the blind spot areas and the forward
facing camera placed behind the
internal rear-view mirror that instead
is used for lane detection and
estimation.
ABSA is designed to help the driver to
avoid mitigate a collision. Torque and
vibration application is however available in the 37 - 112 mph (60 -
180 km/h) speed interval. All the speed
thresholds related to the BSA remain
still valid, since ABSA as mentioned is
BSA extension.
ABSA is intended as a “hands-on”
function meaning that the driver is
required to stay engaged in the
driving all the time with his/her hands
on the steering wheel, in case hands
are not on the steering wheel for a
certain time there cannot be any
steering torque application vibration
included.
System Availability ABSA is designed for an attentive
driver therefore the system is available
only when his/her hands are on the
steering wheel or with hands off for a
very limited amount of time. When
the system is enabled, it will trigger
cluster warning in case at least one
hand is not detected on the steering
wheel.
The torque application as well as the
vibration are suppressed/inhibited in
case of: high driver torque in the
steering wheel, high lateral
acceleration, hands not on the
steering wheel detected for more than
a certain time. Highly dynamic behaviours, driving on
the lane boundary, off course will
prevent the function from working.
FCW braking and stability system
interventions (ESC, ABS) will also
prevent the system from operating.
Changing lane results in system
inhibition for a certain time.
In addition the road must respect
some characteristics such as minimum-
maximum width, lane clearly defined
by two lane boundaries and only in
limited case for a limited time at least
one.
NOTE:
• In case of wet road or raining
conditions the function could be
disabled by the system in order to
minimize the risks.
• With lane boundaries it is mainly
referred to painted lines,
nevertheless the system in good
conditions might properly recognise
as valid lane boundaries also other
types (for example road edges,
curbs, etc..).Driving
