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

Display Warnings and
Maintenance of ACC and FCW
Systems Wipe Front Radar Sensor Warning
This warning will display and a signal
will indicate when conditions
temporarily limit system performance
due to sensor poor or failed signal
reception. This most often occurs at
times of poor visibility, such as in snow
or heavy rain. The ACC and FCW
systems may also become temporarily
blinded due to obstructions, such as
mud, dirt or ice on the radar sensor. In
these cases, the system will be
disabled.
This message can sometimes be
displayed while driving in highly
reflective areas (i.e. tunnels with
reflective tiles, or ice and snow). The
ACC and FCW systems will recover
operation after the vehicle has left
these areas. Under rare conditions,
when the radar is not tracking any
vehicles or objects in its path this
warning may temporarily occur.
If weather conditions are not a factor,
the driver should examine the sensor.
It may require cleaning or removal of
an obstruction. The sensor is located in
the center of the front grille, behind
the Maserati trident. To keep the ACC System operating
properly, it is important to note the
following maintenance items:
• Always keep the sensor clean.
Carefully wipe the sensor lens with a
soft cloth. Be cautious not to
damage it.
• Do not remove any screws from the
sensor. Doing so could cause an ACC
system malfunction or failure and
require a sensor realignment.
• If the sensor or front end of the
vehicle is damaged due to a collision,
see your authorized dealer for
service.
• Do not attach or install any
accessories near the sensor, including
transparent material or aftermarket
grilles. Doing so could cause an ACC
system failure or malfunction. When
the condition that deactivated the
system is no longer present, the
system will return to the “Adaptive
Cruise Control Off” state and will
resume function by simply
reactivating it. NOTE:
If the radar sensor wipe warning
message occurs frequently (e.g. more
than once on every trip) without any
snow, rain, mud, or other obstruction,
have the radar sensor realigned at an
Authorized Maserati Dealer .
Clean Front Windshield Warning
This warning will display and a signal
will indicate when conditions
temporarily limit system performance
due to failed signal reception. This
most often occurs at times of poor
visibility, such as in snow or heavy rain
and fog. The ACC and FCW systems
may also become temporarily blinded
due to obstructions, such as mud, dirt,
or ice on the windshield and fog on
the inside of glass or when driving in
bad weather. In these cases, the
system will have degraded
performance.
The ACC and FCW systems will recover
operation after the vehicle has left
these areas. Under rare conditions,
when the camera is not tracking any
vehicles or objects in its path this
warning may temporarily occur.
If weather conditions are not a factor,
the driver should examine the
windshield and the camera. They mayDriving
5
255

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

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
5
259

Setting options are described in the
following paragraph.
When FCW status for some reason
changes to off, the corresponding
amber warning light on instrument
cluster will light on.
This warning light informs the driver
that FCW is disabled. This warning
light will light even when the
activation of another driver assistance
feature or drive mode (example:
(ESC OFF)) disables the FCW. NOTE:
The FCW system setting is kept in
memory from one key cycle to the
next.
Changing FCW Sensitivity and
Active Braking The default status of FCW Sensitivity is
the “Medium” setting. When the
active braking function (“Forward
Collision Warning Active Braking”)
setting is on, the system warns you of
a possible collision with the vehicle in
front of you when you are farther
away and it applies limited braking.
This gives you the most reaction time
to help avoid a possible collision.
Changing the sensitivity status to the
“Near” setting, allows the system to
warn you of a possible collision with
the vehicle in front of you when you
are much closer. This setting provides
less reaction time than the “Far”
sensitivity setting, which allows for a
more dynamic driving experience.
“Medium” is the intermediate status
between the two described above. NOTE:
• The default values shall appear at
every new ignition cycle: Sensitivity =
“Medium” and Active Braking = on.
• FCW may not react to irrelevant
objects such as objects not in the
path of the car, stationary objects
that are far away, oncoming traffic,
on cross traffic vehicles, or leading
vehicles with the same or higher rate
of speed.
• The active braking (autonomous
braking/braking aid) will not be
provided in case of potential collision
with static object such as guard rails,
walls, etc..).
• FCW will be disabled like ACC (refer
to chapter “Adaptive Cruise Control -
ACC” in this section.
Changing the active braking status to
“Off” prevents the system fromDriving
5
260

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
