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);
• ROM (Roll-Over Mitigation);
• TSM (Trailer Sway Mitigation);
• HDC (Hill Descent Control).
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 sand, or
gravel. The current mode disables the
TCS portion of the ESC and raises theDriving

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

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 it is
recommended to drive without CC.
WARNING!
Electronic Cruise Control can be
dangerous where the system cannot
maintain a constant speed. 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, 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 a 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 vehicleDriving

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. 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 also a
chime 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
The 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 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 may
require cleaning or removal of an
obstruction.Driving

294

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 Towing a Trailer
WARNING!
Towing a trailer when using ACC can
lead to serious system failures which
can cause severe accidents.
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

(Continued)
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.
NOTE:
FCW system is not intended for
towing: this could lead the system to
malfunctions and/or to late reaction.
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 jerk. If
the driver does not take action 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, the 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 strong
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 on
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 jerk
too.
• The FCW system is intended for
on-road use only. If the vehicle is
taken off-road, the FCW system
should be deactivated to prevent
unnecessary warnings. If the vehicle
ride height is set to “Off Road 1” or
“Off Road 2”, the FCW system will be
automatically deactivated.
• FCW will automatically deactivated
when
(ESC OFF) button is pressed
(LED light up) and when HDC is
active.
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 toDriving
