Brake and Stability Control
System The vehicle is equipped with an
Electronic Stability Control System
(ESC), which helps to maintain
directional control in the event of loss
of grip of the tires. The system is able
to detect potentially dangerous
situations for the stability of the
vehicle and automatically sets the
brakes on all four wheels in a
differentiated manner, in order to
provide a torque settlement of the
vehicle.
ESC includes the following subsystems:
• ABS (Anti-lock Braking System);
• EBD (Electronic Brake-force
Distribution);
• TCS (Traction Control System);
• BAS (Brake Assist System);
• BTO (Brake Throttle Override);
• HSA (Hill Start Assist).
WARNING!
• These systems cannot prevent the
natural laws of physics from
affecting the vehicle, nor can they
increase traction, braking or steering
efficiency beyond that afforded by the condition of the vehicle brakes
and tires.
• These systems cannot prevent
collisions, including those resulting
from excessive speed in turns,
following another vehicle too
closely, or hydroplaning.
• The capabilities of a vehicle
equipped with these systems must
never be exploited in a reckless or
dangerous manner that could
jeopardize the driver’s and the
passenger’s safety or the safety of
others.
Electronic Stability Control
(ESC) This system enhances directional
control and stability of the vehicle
under various driving conditions. The
ESC corrects over steering and under
steering of the vehicle by applying the
brake to the appropriate wheel.
Engine power may also be reduced to
assist in counteracting the conditions
of instability and maintain the right
direction. The system is also able to
reduce the engine power.
Through sensors fitted on the vehicle,
the ESC system detects the driver’s
chosen direction comparing it to the
one maintained while running. In case of discrepancy between the required
trajectory and the current one, the ESC
system brakes the appropriate wheel
to counteract over or under steering.
• Oversteer - when the vehicle is
turning more than appropriate for
the steering wheel position.
• Understeer - when the vehicle is
turning less than appropriate for the
steering wheel position.
The ESC system has two available
operating modes:
ESC on
This is the normal ESC operating mode.
At each start-up of the vehicle, the ESC
system is set in this mode and should
be used for most driving conditions.
The ESC should only be turned off for
specific reasons as pointed out in the
following paragraphs.
ESC off
The “ESC off” mode is aimed for a
more spirited driving experience but
also purposeful for driving in deep
snow, sand, or gravel. The current
mode disables the TCS portion of the
ESC and raises the threshold for ESC
activation, allowing higher wheel spin
than normally granted by the ESC
system. The
(ESC OFF) button is
fitted beside the gear shift lever: toDriving

safety system and is not designed to
prevent accidents.
The ACC allows driver to keep Cruise
Control active in limited or moderate
traffic conditions with no need to
constantly restore the Cruise Control.
The ACC uses a radar sensor, located
on the front grille behind the trident,
and the forward-facing camera behind
the internal rear-view mirror to detect
the presence of a vehicle ahead at a
close distance and moving in the same
direction.
This vehicle, in this chapter, will be
indicated as "target vehicle" or
"vehicle ahead".
NOTE:
• If the sensor detects no vehicle
ahead, the ACC system will maintain
set steady speed.
• If the ACC sensor detects a vehicle ahead, the ACC system automatically
kicks in by slightly accelerating or
braking (to avoid exceeding the
initially set speed) so that the vehicle
keeps present distance, trying to
adapt to the speed of the detected
vehicle ahead.
WARNING!
• The Adaptive Cruise Control (ACC) is
designed to increase vehicle driving
comfort. It must not be considered
as a means of replacing the required
attention of the driver. The driver is
always required to drive carefully.
The driver is always required to pay
utmost attention to driving
conditions (road, traffic, weather)
and style (speed, distance from
sensed vehicle ahead, brake use).
Driver has the full responsibility of
the vehicle therefore his attention is
crucial to keeping vehicle control, in
particular when approaching curves
and situations with heavy traffic.
Failure to follow these warnings can
result in a collision and death or
serious personal injury.
• In some driving scenarios, the ACC
could have detection problems. In
such cases, the ACC could kick in late or unexpectedly. The driver must be
careful since his/her intervention
could be necessary.
• It is always the driver’s responsibility
to obey speed limits and to keep
minimum legal distance to the
preceding vehicle.
• ACC system can decelerate only with
limited braking, it cannot execute
emergency braking.
The ACC system:
•
Does not activate/react in the
presence of pedestrians, bicycles,
incoming traffic from the opposite
direction and steady objects such as a
vehicle stuck in a traffic jam.
• Is meant for the use on highways and
well-built roads, not for city traffic or
mountain roads.
• May not have enough time to react
and/or decelerate sufficiently on
vehicles when lane is changed too
quickly or the relative speed is too
high. In such cases the driver has to
react appropriately and without any
acoustic/visual and warning.
• Cannot consider road, traffic and
weather conditions and might prove
limited when visibility is poor.
• Does not always fully recognize
complex driving conditions and thisDriving

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

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

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

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.
