If system does not detect the presence
of any vehicles ahead, only the bars
referred to set distance will be
displayed.
When system detects the presence of a
vehicle ahead, it is displayed in front
of the bars (see example in the figure).
To increase or decrease the number of
bars, corresponding to the gap from vehicle ahead, press and release the
distance setting button.
Each press and release of the button
changes the gap starting from 3 bars
(default distance) and moving in a
sequential way towards the minimum
distance: 3 → 2 → 1 → 4 → 3 → 2 → 1 → 4 and so
on.
If there is no vehicle ahead, the
vehicle will maintain the set speed. If a
slower moving vehicle is detected in
the same lane, the system displays the
target vehicle icon before the bars.
From that moment, the system adjusts
the vehicle speed automatically to
maintain the distance setting,
regardless of the set speed.
The vehicle will then maintain the set
distance until:
• The vehicle ahead accelerates to a
speed above the set speed. • The vehicle ahead moves out of the
lane or view of the sensor.
• The distance setting is changed.
• The driver disables the system.
The maximum braking applied by ACC
is limited; however, the driver can
always apply the brakes manually, if
necessary. Obviously, any time the ACC
system automatically operates the
brakes, the brake lights will turn on as
if the driver was braking.
A Proximity Warning on display will
alert the driver if ACC predicts that its
maximum braking level is not
sufficient to maintain the set distance.
If this occurs, a visual alert will flash
on the display and a chime will sound
while ACC continues to apply its
maximum braking capacity.Driver Assist Page

NOTE:
The displayed warning is a warning for
the driver to take action and does not
necessarily mean that the Forward
Collision Warning (FCW) system is
applying the brakes autonomously.
Overtake Aid When driving with ACC engaged and
following a target vehicle, the system
will provide an additional acceleration
to assist in passing vehicles in front.
This additional acceleration is
triggered when the driver utilizes the
left turn signal to start overtaking. In
locations with left hand drive traffic,
overtake aid is active only when
passing on the left hand side of the
target vehicle.
When a vehicle goes from a location
with left hand drive traffic to a
location with right hand drive traffic,
the ACC system will automatically
detect traffic direction. In this
condition, overtake aid is active only
when passing on the right side of the
target vehicle. This additional
acceleration is triggered when the
driver utilizes the right turn signal to
start overtaking. In this condition the
ACC system will no longer provide
overtake aid on the left side until it determines that the vehicle has moved
back to a location with left hand drive.
ACC Operation Before and
During Stop If an ACC host vehicle follows a target
vehicle to a standstill, after two or
three seconds the system will not be
able to resume driving the car
autonomously. In this condition, TFT
displays an instruction message pop up
for 5 seconds.
When the ACC system brings the
vehicle to a standstill while following a
target vehicle, the brakes are released
after two-three seconds after the stop
and at the same time the system
inserts the parking brake. When
parking brake engages the ACC
deactivates going to ready state.
At this point the driver must reengage
the system acting on the multifunction
control (RES + or SET -) or alternatively
on the accelerator pedal. While ACC
with Stop is holding your vehicle at a
standstill, if the driver unbuckles the
seatbelt or opens the door, the ESC
system will activate the EPB. During
standstill, ACC system monitors the
occupant detection signals: if the
driver's seatbelt becomes unbuckled,
the ACC system shall be cancelled
when the EPB is applied. WARNING!
• When the ACC system is resumed,
the driver must ensure that there are
no pedestrians, vehicles or objects in
the path of the vehicle. Failure to
follow these warnings can result in a
collision and death or serious
personal injury.
• During the automatic stopping
behind a vehicle in some rare cases it
may happen that the system does
not recognize the rearmost point of
the vehicle ahead but a target under
the vehicle ahead (e.g. the back axis
of a truck with a high loading edge
or a bumper of a vehicle although
overhanging load is hanging over
the vehicle’s rear). In these cases the
system cannot guarantee the
appropriate stopping distance
leading to collision in the worst case.
For this reason the driver has to be
attentive and ready to brake during
automatic stops.Driving

require cleaning or removal of an
obstruction.
When the condition that created
limited functionality is no longer
present, the ACC and FCW systems will
return to full functionality.
NOTE:
If the windshield wiper warning
message occurs frequently (e.g. more
than once on every trip) without any
snow, rain, mud, or other obstruction,
have the windshield and forward-
facing camera inspected at an
Authorized Maserati Dealer .
Service ACC/FCW Warning
If the ACC and FCW systems turn off,
and the system displays a service
warning, there may be an internal
system fault or a temporary
malfunction that limits functionality.
Although the vehicle is still driveable
under normal conditions, ACC and
FCW will be temporarily unavailable. If
this occurs, try activating ACC and FCW
again later, following a key cycle. If the
problem persists, contact an
Authorized Maserati Dealer .Precautions while Driving with
ACC Offset Driving
ACC may not detect a vehicle in the
same lane that is offset from your
direct line of travel, or a vehicle
merging in from a side lane. There
may not be sufficient distance to the
vehicle ahead. The offset vehicle may
move in and out of the line of travel,
which can cause your vehicle to brake
or accelerate unexpectedly. Turns and Bends
When driving on a curve with ACC
engaged, the system may decrease the
vehicle speed and acceleration for
stability reasons, with no target vehicle
detected. Once the vehicle is out of
the curve the system will resume your
original Set Speed. This is a part of
normal ACC system functionality.
Moreover, the radar sensor might
detect a vehicle on a nearby lane or no
longer detect the target vehicle.Driving

Using ACC on Hills
When driving on steep hills, ACC may
not detect a vehicle in your lane when
the vehicle reaches the crest.
Depending on the speed, vehicle load,
traffic conditions, and the steepness of
the hills, ACC performance may be
limited.
Lane Changing
ACC may not detect a vehicle until it is
completely in the lane in which you
are traveling.
In the illustration shown, ACC has not
yet detected the vehicle changing lane
and it may not detect the vehicle until
it is too late for the driver to take
action. ACC may not detect a vehicle
until it is completely in the lane. There
may not be sufficient distance to the
lane changing vehicle.
Always be attentive and ready to
apply the brakes if necessary. Narrow Vehicles
Some narrow vehicles (like
motorcycles) traveling near the outer
edges of the lane or edging into the
lane are not detected until they have
moved fully into the lane. There may
not be sufficient distance to the
vehicle ahead. Stationary Objects and Vehicles
ACC does not react to stationary
objects and stationary vehicles. For
example, ACC will not react in
situations where the vehicle you are
following exits your lane and the
vehicle ahead is stopped in your lane.
Always be attentive and ready to
apply the brakes if necessary.

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
268

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.

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

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 directional
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.
