Driver Override If the driver presses the accelerator
pedal while the CC is on, such as to
overtake another vehicle, and exceeds
the set speed limit, the system will
temporarily deactivate the CC. During
the event, the speed indication below
the
green light will be blinking.
When the accelerator pedal is
released, the vehicle will return to the
set speed and the
green light with
below the set speed with steady light
will be displayed.
Resume Speed To resume a previously set speed, push
upward the multifunction switch (RES
+) and release. The
green light
with below the set speed will
illuminate on the instrument cluster.
Resume can be used at any speed
above 18 mph (30 km/h). Using Electronic Cruise Control
on Hills The transmission may be downshifted
on hills to maintain the vehicle set
speed. The CC system maintains set
speed up and down hills. A slight
speed change on moderate hills is
normal. On steep slopes, a greater
speed loss or gain may occur so we
recommend to drive without CC.
WARNING!
Electronic Cruise Control can be
dangerous where the system cannot
maintain a constant speed. Your
vehicle could go too fast for the
conditions, and you could lose control
and have an accident. Do not use
electronic Cruise Control in heavy
traffic or on winding, icy,
snow-covered or slippery roads.Adaptive Cruise Control –
ACC (optional) ADAS Equipments The Adaptive Cruise Control (ACC) is
part of ADAS equipments together
with:
• Lane Keeping Assist (LKA)
• Active Blind Spot Assist (ABSA)
• Forward Collision Warning (FCW)
• Highway Assist (HAS)
• Traffic Sign Assist (TSA).
FCW is a standard equipment while
HAS and TSA are separate functions
that may not be present in the ADAS
equipment. For more details see
“Forward Collision Warning - FCW”,
“Highway Assist - HAS" and "Traffic
Sign Assist - TSA" in this section.
NOTE:
LKA and ABSA are described in the
relevant chapters of this section.
ACC Preview The Adaptive Cruise Control (ACC)
further increases the drive comfort
ensured by the Cruise Control when
driving on highways and freeways.
Always consider that ACC is not aDriving
5
247

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
5
248

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.

The ACC is not activated in the
following conditions:
• When braking.
• When parking brake is activated.
• When automatic transmission is in P
(Park), R (Reverse) or N (Neutral).
• When vehicle speed is out of preset
speed range
• When brakes are overheated.
• When driver door is open.
• When the driver’s seat belt is
unbuckled.
• When the road is particularly steep
(both uphill and downhill) at low

Push the ON/OFF button a second time
and release to turn the system off. A
pop-up message is displayed for 2
seconds to indicate that ACC was
disabled.
WARNING!
Leaving the Adaptive Cruise Control
(ACC) system on when not in use is
dangerous. You could accidentally
activate the system or cause it to go faster than you want. Always leave
the system off when you are not
using it.
Setting the Speed When the vehicle reaches the required
speed, press down and release the
multifunction control (SET -). The
display will show set speed
corresponding to vehicle current one.
Speed value will be indicated below
the
green symbol and above the
distance bars, in the center of the
display.
Remove foot from accelerator pedal
and vehicle will continue at set speed.
Driver Override If the driver accelerates beyond the set
speed or faster than the car would do
with ACC engaged, the set speed
below the
green light will blink and the time gap bars will vanish to
indicate that in this condition the
system cannot control the distance
between vehicle and sensed vehicle
ahead. Vehicle speed will be
determined only by the accelerator
pedal position.
Changing Speed Setting Once speed is set, driver can increase
or decrease it by respectively pressing
multifunction control up (RES +) or
down (SET -). Speed can be increased
or decreased in two ways:
• Pressing control once, set speed will
increase or decrease by one unit
corresponding to 1 mph (1 km/h).
• Hold the control to increase or
decrease set speed by 5 mph
(10 km/h) at a time.
NOTE:
• When pressing the multifunction
control up (RES +) or down (SET -),
the new set speed will be the current
speed of the vehicle.
• When using (SET -) control to
decelerate, if the engine braking
power does not slow down the
vehicle sufficiently to reach the set
speed, the brake system will
automatically slow down the vehicle.

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

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

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.

Information The “Regulatory Information” for all
the radio frequency and radar devices
can be consulted by accessing the
“Services” section on the website

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.

injury or death.
• The following list does not fully
represent all situations in which HAS
may not function as intended. Do
NOT solely rely on the HAS system
to control the vehicle. It is the
driver’s responsibility to stay alert
and safely control the vehicle at all
times.
• If the windshield is replaced, you
must have the forward-facing
camera remounted and aligned by
an Authorized Maserati Dealer.
Many factors can impact the
performance
of HAS
