WARNING!
• The ABS contains sophisticated
electronic equipment that may be
susceptible to interference caused
by improperly installed or high
output radio transmitting
equipment. This interference can
cause possible loss of anti-lock
braking capability. Installation of
such equipment should be
performed by qualified Maserati
personnel.
• Pumping the Anti-Lock Brakes will
diminish their effectiveness.
Pumping brakes makes the stopping
distance longer. Just press firmly on
your brake pedal when you need to
slow down or stop.
• The ABS installed to this vehicle
does not control trailer braking
system. Pay utmost attention when
driving on slippery ground since the
trailer traction might get poorer.
• Do not modify the vehicle braking
system to control the trailer brakes.
The hydraulic system controlling
vehicle braking must remain
independent from trailer braking
system. Traction Control System (TCS) The current device is an integral part
of the ESC system. It operates
automatically by reducing the power
transmitted by the engine in case of
slipping, loss of grip on wet floor
(aquaplaning), acceleration on
slippery snow-covered or frozen
surfaces, etc.
Activating under slip conditions
different control systems:
• if slippage affects both drive wheels,
it reduces the power transmitted by
the engine;
• if slippage only affects one drive
wheel, it brakes the slipping wheel
automatically.
Brake Assist System (BAS) This system completes the ABS system
by optimizing the vehicle braking
capacity during emergency brake
maneuvers. The system detects an
emergency braking situation by
sensing the rate and amount of brake
application and then applies optimum
pressure to the brakes in order to help
reduce braking distances.
The quick brake coupling is optimal
for BAS performances. In order to fully
exploit the system, apply continuous
brake pedal pressure during the entire vehicle stop sequence. Do not reduce
brake pedal pressure earlier than
required. Once the brake pedal is
released, the BAS is deactivated.
Brake Throttle Override (BTO) To complete the range of systems that
assist braking, the vehicle is equipped
with BTO, which is designed to stop
the vehicle even when it is during
acceleration. If the brake pedal is
depressed together with the
accelerator, the system does not
consider as “conflict” the sequence
“brake-first-then-accelerator” of pedal
application and it will not engage the
BTO. When the system recognizes that
the accelerator pedal is stuck pressed
and the sequence “accelerator-first-
then-brake-pressed” (this sequence is
recognized as a “conflict”), the engine
power will be automatically reduced
and, if the driver continues to depress
the accelerator and the brake pedal,
the system can make the vehicle come
to a complete stop.
Additionally, if the brake pedal is
released when the accelerator is still
stuck pressed, the corresponding
engine torque increase gradually to a
safe value.
During this event, the ETC light
indicator will illuminate. The systemDriving

exits from this strategy when the
accelerator pedal is completely
unstuck.
Hill Start Assist (HSA) The HSA system is designed to assist
the driver when starting a vehicle
uphill. HSA will maintain the level of
brake pressure applied for a short
period of time also after releasing the
brake pedal.
If the driver does not apply the
throttle during this short period of
time, the system will release brake
pressure and the vehicle will start
sloping down. The system will release
brake pressure proportionally to the
amount of throttle/torque applied as
the vehicle starts to move in the
chosen direction.
HSA Activation Criteria
The following criteria must be met in
order for HSA to activate:
• vehicle is stationary;
• gear selection matches vehicle uphill
direction (i.e., vehicle facing uphill is
in forward gear; vehicle backing
uphill is in reverse gear).
HSA will work in R (Reverse) and all
forward gears when the activation
criteria have been met. The system will not activate if the
transmission is placed in N (Neutral) or
P (Park).
Roll-Over Mitigation (ROM) This system anticipates the potential
for wheel lift by monitoring the
driver's steering wheel input and the
speed of the vehicle. When ROM
determines that the rate of change of
the steering wheel angle and vehicle's
speed are sufficient to potentially
cause wheel lift, it then applies the
appropriate brake and may also
reduce engine power to lessen the
chance that wheel lift will occur.
ROM will only intervene during very
severe or evasive driving maneuvers.
ROM can only reduce the chance of
wheel lift occurring during severe or
evasive driving maneuvers. It cannot
prevent wheel lift due to other factors,
such as road and off-road conditions,
leaving the roadway, or striking
objects or other vehicles.
WARNING!
Many factors, such as vehicle loading,
road and off-road conditions, and
driving conditions, influence the
chance that wheel lift or rollover may occur. ROM cannot prevent all wheel
lift or roll-overs, especially those that
involve leaving the roadway or
striking objects or other vehicles. The
capabilities of a ROM-equipped
vehicle must never be exploited in a
reckless or dangerous manner, which
could jeopardize the user’s safety or
the safety of others.
Trailer Sway Mitigation (TSM) TSM uses sensors in the vehicle to
recognize an excessively swaying
trailer and will take the appropriate
actions to attempt to stop the sway.
The system may reduce engine power
and apply the brake of the
appropriate wheel(s) to counteract the
sway of the trailer. TSM will become
active automatically once an
excessively swaying trailer is
recognized.
TSM cannot stop all trailers from
swaying. Always use caution when
towing a trailer and follow the trailer
tongue weight recommendations.
Refer to “Trailer Towing” in this
section for further information. When
TSM is functioning, the “ESC
Activation/Malfunction Indicator
Light” will flash (see “Instrument
Cluster” in section “DashboardDriving

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 and initiate a steering
maneuver to try to prevent the lane
exit.
To detect lane lines, the system uses
the forward-facing camera behind of
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. 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/Driving
5
301

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 trajectory 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. 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 only 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, trailer connected to the
proper control module, 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 lane 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 for a limited time, the presence of
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 theDriving
5
302

transition from LKA to Active Blind
Spot Assist (ABSA) (if this latter is on
and properly configured).
Function Description and
Operating Mode 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
enable 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 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
estimate properly the lane);
• 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 to properly handle the
situation;
• Yellow flashing line: the graphic is
shown whenever the system detects
a very imminent lane departure, at
this can be added torque and
steering vibration 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 this screen, with only
LKA system activated and with LKA
and ACC systems activated, 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. Driver Assist PageDriving

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 heavy 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.Non-Driver Assist PageDriving

System is Faulty
The BSA system cannot properly
operate due to a fault of its
components, or because the area on
the rear bumper fascia where the
radar sensors are located is dirty. In
these cases the amber warning light
and the related message will be
displayed on the instrument cluster.
In these cases avoid using the system
and have the vehicle inspected at an
Authorized Maserati Dealer .
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. 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 trajectory 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.

System sensitivity can be set to “Early”,
“Medium” (default mode) or “Late”.
System strength can be set to "Low",
"Medium" (default mode) or "High".
NOTE:
The ABSA system will store the current
operating mode when the vehicle is
shut off. Each time the vehicle is
started, the previously-stored mode
will be recalled and used.
Meanings of Settings
When "Visual & Haptic" is selected and
of course ABSA is enabled, then two
following menus will be used by the
system.
• ABSA "Sensitivity": it tunes the
distance to the lane boundary where
the system will start to apply steering
torque. • ABSA “Strength": it tunes the
steering torque value to have a
stronger or weaker trajectory
correction/deviation.
Blind Spot Assist in "Visual & Haptic"
Mode
When the system is on and configured
“Visual & Haptic” then the ABSA is
enabled and to the conventional visual
warnings is added the steering torque
and vibration.
When operating in this mode, the
system will provide a visual alert in the
appropriate outside rear-view mirror
when it detects a vehicle or an object
in the detection areas monitored by its
sensors. In case of turn indicator
activation on the appropriate side, the
system will react with a torque on the
steering wheel to try to prevent the
lane change and therefore to
avoid/mitigate the collision. The
torque on the steering is applied when
the car is very close to the lane
boundary as a further feedback to
warn the driver of the unsafe
maneuver.
NOTE:
• The steering torque is not supplied if
the system is not able to estimate a
lane and if the turn indicator from
the appropriate side is not inserted. • 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.
WARNING!
• Risk of accident despite steering
torque application of Active Blind
Spot Assist (ABSA).
• A course-correcting steering torque
application cannot always prevent a
collision.
• The driver is always required to
steer, brake or accelerate themself,
especially if ABSA warns or makes a
course correcting steer intervention.
• Always maintain a safe distance at
the sides.
• Steering torque application may be
interrupted at any time by counter
steering by the driver.

System Cancellation The HAS system will cancel (without
driver intervention) if either of the
following actions occur:
• Curve that is too tight.
• When leaving the grip of the hands
on the steering wheel.
• Vehicle exits the highway or limited
access freeway.
• Lane line markers aren’t detected by
the forward facing camera.
• Any ADAS system faults.
• ACC cancellation.
• Vehicle speed exceeds the maximum
limit. • Lateral accelerations exceeds the
limits.
NOTE:
• When HAS cancels, the
symbol
will turn red then grey.
• 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.
System Limitations HAS is unable to guide the vehicle
when the following conditions occur.
• Lane markings are not clear or
visibility is poor (i.e. heavy rain,
snow, fog, etc.).
• Obstructed, covered or damaged
forward-facing camera or sensor.
• When driving on hills or sharp curves.
• When approaching toll booths.
• When the highway entrance or exit is
wider than 20 ft (6 meters).
• Bright light (ex. direct sunlight or
glare) facing the forward camera. WARNING!
Many unforeseen conditions can occur
that can affect the performance of
Highway Assist (HAS). Always keep
this in mind and drive attentively. It is
the drivers responsibility to keep
control of the vehicle at all times.
