“Off Road 2” ride height is limited
instead up to a max speed of 25 mph
(40 km/h). In case the vehicle speed
should exceed this limit, ride height
will be put automatically to “Off Road
1” while driving mode will remain
“OFF ROAD”.
An advantage of the higher ground
clearance is a better view of the road,
allowing you to anticipate problems.
A higher clearance and the longer
travel of the suspension might allow
the vehicle to overcome some
obstacles.
A higher ground clearance means a
higher center of gravity. If at all
possible, avoid sharp turns or abrupt
maneuvers. Failure to operate this
vehicle correctly may result in loss of
control or vehicle rollover .
Although the pneumatic suspension
system contributes to limiting these
risks by setting precautionary speed
thresholds, the driver must always pay
utmost attention and drive carefully.
WARNING!
“Off Road 2” ride height must always
be selected in case of water fording.
Please remember water fording limits:
max depth of the water must be lower than 19 in (50 cm) and crossing
speed lower than 5 mph (8 km/h).
In “OFF ROAD” drive mode, also
engine,
transmission settings are
changed in order to provide the most
suitable level of torque and selected
gear to improve traction on
low-adherence condition and uphill
climbing.
WARNING!
In case of downhill, the use of the Hill
Descent Control (HDC) is
recommended, especially for relevant
slope and in case of low-adherence
conditions.
Also suspensions (Skyhook Continuous
Damping
Control) are set
to a specific
calibration in “OFF ROAD” drive
mode, in order to obtain the right
damping force provided by the shock
absorbers, combined with the
increased ride heights “Off Road 1”
and “Off Road 2”.
Driving Through Water Set maximum ride height “Off Road
2” before driving through water.
Although your vehicle is capable of
driving through water, a number precautions must be considered
before entering the water.
NOTE:
Your vehicle is capable of water
fording to a maximum of 19 in (50 cm)
of water. To maintain optimal
performance of your vehicle’s heating
and ventilation system it is
recommended to switch the system
into recirculation mode during water
fording.
CAUTION!
When driving through water, do not
exceed 5 mph (8 km/h). Always check
water depth before entering, as a
precaution. Check all fluids
afterwards: driving through water
may cause damage to engine and
driveline that may not be covered by
the new vehicle limited warranty.
Driving through water more than a
few
inches/centimeters deep will
require extra caution to ensure safety
and prevent damage to your vehicle. If
you must drive through water, try to
determine the depth and the bottom
condition (and location of any
obstacles) prior to entering. Proceed
with caution and maintain a steadyDriving

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
5
273
Page 278 of 436

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: to deactivate the system see
“Drive Mode” in this section.
WARNING!
In SPORT mode the ESC control
thresholds are higher for maximum
performance on dry road surface. To
ensure maximum security of the ESC,
it is recommended not to activate
SPORT mode on surfaces with
medium- and low-grip (e.g., wet,
snow, dirt, etc..) with ESC system
active (
(ESC OFF) button not
pressed).
NOTE:
• When in “ESC of f” mode, the TCS
functionality of ESC is deactivated
(except for the limited slip feature
described in the TCS paragraph of
this chapter). All other stability
features of ESC function regularly.
• To improve the vehicle's traction
when driving with snow chains, or
when starting off in deep snow,
sand, or gravel, it may be desirable
to switch to the “ESC off” mode by pressing the
(ESC OFF) button and
remain in this operational mode no
longer than needed. Once the
situation requiring “ESC off” mode is
overcome, turn the ESC on again by
pressing the
(ESC OFF) button. This
may also be performed while in
motion.
Anti-Lock Braking System (ABS)
and Electronic Brake-force
Distribution (EBD) The Anti-Lock Braking System (ABS)
provides increased vehicle stability and
brake performance under most
braking conditions. The system
automatically “pumps” the brakes
during severe braking to prevent
wheel lock-up.
The Electronic Brake-force Distribution
(EBD) prevents the rear wheels from
over-braking and provides greater
control of available braking forces
applied to the rear axle.
WARNING!
The ABS helps prevent the wheels
from locking, but it does not increase
the physical grip limits between the
tires and the road. Therefore, always
keep a safe distance from the vehicle in front of yours and reduce your
speed when entering a curve.
NOTE:
• When
the vehicle's speed is higher
than 7 mph (11 km/h), you may hear
a slight clicking sound as well as
other motor noises. The system is
performing a self-check cycle to
ensure that the ABS is working
properly.
• This self-check occurs each time the
vehicle is started and accelerated
past 7 mph (11 km/h).
ABS is activated during braking under
certain road or stopping conditions.
ABS-inducing conditions can include
ice, snow, gravel, bumps, railroad
tracks, loose debris.
You may also experience the following
when the brake system goes into Anti-
Lock:
• The ABS motor running (it may
continue to run for a short time after
the vehicle stops).
• The clicking sound of solenoid valves.
• Brake pedal pulsations.
• A slight drop or fall away of the
brake pedal at the end of the stop.
These are all normal characteristics of
ABS functioning.Driving
5
274
Page 279 of 436

WARNING!
• The ABS contains sophisticated
electronic equipment that may be
susceptible to interference caused
by improperly installed or high
output radio transmitting
equipment. This interference can
cause possible loss of anti-lock
braking capability. Installation of
such equipment should be
performed by qualified Maserati
personnel.
• Pumping the Anti-Lock Brakes will
diminish their effectiveness.
Pumping brakes makes the stopping
distance longer. Just press firmly on
your brake pedal when you need to
slow down or stop.
• The ABS installed to this vehicle
does not control trailer braking
system. Pay utmost attention when
driving on slippery ground since the
trailer traction might get poorer.
• Do not modify the vehicle braking
system to control the trailer brakes.
The hydraulic system controlling
vehicle braking must remain
independent from trailer braking
system. Traction Control System (TCS) The current device is an integral part
of the ESC system. It operates
automatically by reducing the power
transmitted by the engine in case of
slipping, loss of grip on wet floor
(aquaplaning), acceleration on
slippery snow-covered or frozen
surfaces, etc.
Activating under slip conditions
different control systems:
• if slippage affects both drive wheels,
it reduces the power transmitted by
the engine;
• if slippage only affects one drive
wheel, it brakes the slipping wheel
automatically.
Brake Assist System (BAS) This system completes the ABS system
by optimizing the vehicle braking
capacity during emergency brake
maneuvers. The system detects an
emergency braking situation by
sensing the rate and amount of brake
application and then applies optimum
pressure to the brakes in order to help
reduce braking distances.
The quick brake coupling is optimal
for BAS performances. In order to fully
exploit the system, apply continuous
brake pedal pressure during the entire vehicle stop sequence. Do not reduce
brake pedal pressure earlier than
required. Once the brake pedal is
released, the BAS is deactivated.
Brake Throttle Override (BTO) To complete the range of systems that
assist braking, the vehicle is equipped
with BTO, which is designed to stop
the vehicle even when it is during
acceleration. If the brake pedal is
depressed together with the
accelerator, the system does not
consider as “conflict” the sequence
“brake-first-then-accelerator” of pedal
application and it will not engage the
BTO. When the system recognizes that
the accelerator pedal is stuck pressed
and the sequence “accelerator-first-
then-brake-pressed” (this sequence is
recognized as a “conflict”), the engine
power will be automatically reduced
and, if the driver continues to depress
the accelerator and the brake pedal,
the system can make the vehicle come
to a complete stop.
Additionally, if the brake pedal is
released when the accelerator is still
stuck pressed, the corresponding
engine torque increase gradually to a
safe value.
During this event, the ETC light
indicator will illuminate. The systemDriving

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

• 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
speed.
• When ride height is "Off Road 1" or
“Off Road 2”, or drive mode is "OFF
ROAD".
• When drive mode
(ESC OFF) is
selected.
• When the door is opened at low
speed.
• When there has been an ESC event
in the last 5 seconds, or is still active.
• When there is an object too close in
front of the vehicle.
It is possible that more than one
system is active at the same time such
as ACC and ABSA just to mention
some.
While activation of ACC and CC at the
same time is impossible.

accelerator pedal (see “ACC
Operation Before and During Stop”
in this chapter).
• The ACC system maintains set speed
when driving up hill and down hill.
However, a slight speed change on
moderate hills is normal. In addition,
downshifting may occur while
climbing uphill or descending
downhill. This is normal operation
and necessary to maintain set speed.
When driving uphill and downhill,
the ACC system will cancel if the
braking temperature exceeds normal
range.
Temporary Deactivation A soft tap on the brake pedal, pushing
the multifunction control (CANC), or
normal brake pressure while slowing
the vehicle will temporarily deactivate
the ACC without erasing the set speed
memory. The
white light will appear
on the display with below the set
speed.
Conditions for Disabling and
Deactivation Besides the cases specified in the
previous paragraph, the following
conditions will disable the system:
• Anti-Lock Brake (ABS) kicks in. • Transmission lever is not in D (Drive).
• “CORSA” drive mode (TROFEO
version only) is set.
• Ride height is set to “Off Road 1” or
“Off Road 2”.
• The Electronic Stability Control and
the Traction Control System
(ESC/TCS) activate.
• Vehicle parking brake is operated.
• The driver safety belt is unbuckled at
low speed.
• The driver door is ajar at low speed.
• The driver disabled the ESC using the
(ESC OFF) button on central
console.
• The road is too steep both uphill and
downhill at low speed.
The system is deactivated and set
speed is deleted from system memory,
if the ACC ON/OFF button is pressed or
if ignition device is turned to OFF .
Resuming Speed If a speed setting is stored in system
memory, press the multifunction
control (RES +) up and take foot off
the accelerator pedal. The last set
speed will be displayed. WARNING!
The resume function should be used
only when road and traffic conditions
allow it. Resuming a too high or too
low speed for current traffic and road
conditions could cause a harsh vehicle
acceleration or deceleration which
could increase the risk of collisions
and death or serious injury.
Setting the ACC Gap The specified ACC gap can be set by
varying the distance setting among
the four possible options identified by
the number of horizontal bars:
• Maximum (longest) distance: 4 bars.
• Long distance: 3 bars (default
distance).
• Medium distance: 2 bars.
• Short distance: 1 bar.
Using this distance setting and the
vehicle speed, ACC calculates and sets
the gap to the vehicle ahead.
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).Driving

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 trajectory 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. System Availability The ADAS systems (LKA, CC, ACC, FCW
and HAS) help the driver while driving.
These systems can be set and
monitored simultaneously on the
display, after opening “Driver Assist”
menu (see paragraph “TFT Display:
Menus and Settings” under
“Instrument Cluster” in section
“Dashboard Instruments and
Controls”).
LKA is designed for an attentive driver;
therefore the system is available only
when his/her hands are on the steering
wheel or with hands off only for a very
limited amount of time. When the
system is enabled it will trigger cluster
warning in case at least one hand is
not detected on the steering wheel.
The torque application as well as the
vibration are suppressed/inhibited in
case of: high driver torque in the
steering wheel, high lateral
acceleration, trailer connected to the
proper control module, hands not on
the steering wheel detected for more
than a certain time.
High dynamic driving behaviors,
driving on the lane boundary or
driving off course will prevent the
function from working. FCW braking
and stability system interventions (ESC, ABS) will also prevent the system from
operating. Changing lane results in
system inhibition for a certain time. In
addition, the driver must respect some
road characteristics such as
minimum-maximum width, lanes
clearly defined by two lane boundaries
and for a limited time, the presence of
at least one lane boundary.
NOTE:
• In case of wet road or raining
conditions the function could be
disabled by the system in order to
minimize the risks.
• With lane boundaries it is mainly
referred to painted lines,
nevertheless the system in good
conditions might properly recognize
as valid lane boundaries also other
types (for example road edges, curbs,
etc..).
Being this function used to prevent
unintentional lane change/lane drift, it
will be temporary suppressed/inhibited
by a turn indicator activation,
therefore, graphic warning, steering
torque application and vibration will
be terminated. In this condition in case
of a vehicle detected by the Blind Spot
Assist (BSA) system in the covered area
on the proper side, there can be theDriving
5
302
Page 307 of 436

transition from LKA to Active Blind
Spot Assist (ABSA) (if this latter is on
and properly configured).
Function Description and
Operating Mode Intent of the function is to prevent the
lane departure by warning the driver
through indication on the cluster and
if set applying steering torque and
vibration. Whenever the system is
enable there will be graphic on the
dedicated screen in the driver assist
page and for the others it will be
available in the left top corner of the
cluster screen. The graphic which
intent is to represent at the glance the
system knowledge of the lane in front
of the car, the system suppression
status and warning.
For this a simple colour code has been
adopted for each line (of the two
presented):
• Both grey lines means system is
enabled, not able to operate
(suppression condition present or
lane detection system not able to
estimate properly the lane);
• Left/right grey line: the lane
detection system is not able to
detect that specific lane boundary; • Yellow line: there is a steering
torque intervention in progress that
tries to prevent a departure on that
side, in this situation the warning
should increase the driver attention
requiring him to properly handle the
situation;
• Yellow flashing line: the graphic is
shown whenever the system detects
a very imminent lane departure, at
this can be added torque and
steering vibration if configured by
the customer.
The white lines (one or both) indicates
that the corresponding lane boundary
is detected and the system is capable
to intervene on it.
An example of this screen, with only
LKA system activated and with LKA
and ACC systems activated, can be
found in the following figures:
A: with only LKA system activated,
steering torque in progress to
correct the trajectory towards
the lane center;
B: with LKA and ACC systems
activated, car is crossing the lane
boundary, steering torque and
vibration if configured are in
progress when this graphic is
shown. Driver Assist PageDriving

System is Faulty
The BSA system cannot properly
operate due to a fault of its
components, or because the area on
the rear bumper fascia where the
radar sensors are located is dirty. In
these cases the amber warning light
and the related message will be
displayed on the instrument cluster.
In these cases avoid using the system
and have the vehicle inspected at an
Authorized Maserati Dealer .
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. Active Blind Spot Assist -
ABSA (optional, with ACC
only) ABSA system is only available on
vehicles equipped with ACC system
and represents an addition to the BSA
previously described (see chapter
"Blind Spot Assist - BSA" of this
section).
ABSA adds to the BSA the possibility in
certain circumstances to avoid and or
mitigate side collisions with vehicles
proceeding in the adjacent lanes by
changing the car trajectory in order to
try to keep it inside the detected/
estimated lane. A steering wheel
vibration is used as further feedback to
warn the driver that the lane change is
not safe.
The main logic core is the front radar,
whereas the sense inputs are the
radars on the rear bumper fascia used
for sensing the presence of vehicle in
the blind spot areas and the forward
facing camera placed behind the
internal rear-view mirror that instead
is used for lane detection and
estimation.
ABSA is designed to help the driver to
avoid mitigate a collision. Torque and
vibration application is however available in the 37 - 112 mph (60 -
180 km/h) speed interval. All the speed
thresholds related to the BSA remain
still valid, since ABSA as mentioned is
BSA extension.
ABSA is intended as a “hands-on”
function meaning that the driver is
required to stay engaged in the
driving all the time with his/her hands
on the steering wheel, in case hands
are not on the steering wheel for a
certain time there cannot be any
steering torque application vibration
included.
System Availability ABSA is designed for an attentive
driver therefore the system is available
only when his/her hands are on the
steering wheel or with hands off for a
very limited amount of time. When the
system is enabled, it will trigger cluster
warning in case at least one hand is
not detected on the steering wheel.
The torque application as well as the
vibration are suppressed/inhibited in
case of: high driver torque in the
steering wheel, high lateral
acceleration, hands not on the steering
wheel detected for more than a
certain time.
