Speed Range of Use Speed mph (km/h)
Minimum 37 (60)
Engaged/activated 37 (60)
Maximum 112 (180)
System Limitation Because of physical limits the system to
properly operate needs good visibility
(it might not work or not properly
operate in case of heavy rain, snow,
wet roads, fog, direct sun on the
camera, dirty windshield, low
illumination etc.)
Sharp turns, slopes and change in
slopes, poor lane boundaries, as well
as construction areas and all the
scenarios described in this paragraph
may challenge the system, therefore
be always ready to prevent any
unexpected behaviour of the car.
Damaged front bumper, windshield
replaced without proper technical
intervention may also lead to system
malfunction or system unavailability.
Other conditions such as faults, but
not explicitly indicated here may also
prevent/interrupt the system
intervention. ABSA Setting ABSA is configurable by the customer
in order to maximize its efficiency
based on the driver driving style and
his/her expectation of the system,
reducing at the same time the possible
invasiveness.
Setting modes can be selected from
the MTC+ System (see "MTC+
"Controls" Screen" in section
"Dashboard Instruments and Controls"
for further information).
Touch "Controls" soft-key to display
the current status of the ABSA system,
if it was in the on state.
To change status, touch the "Active
Blind Spot Assist" soft-key.
To change the system setting, touch
the soft-key on the side.
Driver warnings can be only "Visual",
"Visual & Acoustic" (default mode) or
"Visual & Haptic". System sensitivity can be set to “Early”,
“Medium” (default mode) or “Late”.
System strength can be set to "Low",
"Medium" (default mode) or "High".
NOTE:
The ABSA system will store the current
operating mode when the vehicle is
shut off. Each time the vehicle is
started, the previously-stored mode
will be recalled and used.
Meanings of Settings
When "Visual & Haptic" is selected and
of course ABSA is enabled, then two
following menus will be used by the
system.
• ABSA “Sensitivity": it tunes the
distance to the lane boundary where
the system will start to apply steering
torque.Driving
5
272

• ABSA “Strength": it tunes the
steering torque value to have a
stronger or weaker directional
correction/deviation.
Blind Spot Assist in "Visual & Haptic"
Mode
When the system is on and configured
“Visual & Haptic” then the ABSA is
enabled and to the conventional
visual warnings is added the steering
torque and vibration.
When operating in this mode, the
system will provide a visual alert in the
appropriate outside rear-view mirror
when it detects a vehicle or an object
in the detection areas monitored by its
sensors. In case of turn indicator
activation on the appropriate side, the
system will react with a torque on the
steering wheel to try to prevent the
lane change and therefore to
avoid/mitigate the collision. The
torque on the steering is applied
when the car is very close to the lane
boundary as a further feedback to
warn the driver of the unsafe
maneuver.
NOTE:
• The steering torque is not supplied if
the system is not able to estimate a
lane and if the turn indicator from
the appropriate side is not inserted. • The presence of the hands on the
steering wheel is detected by a logic
combination of a capacitive sensor
installed in the steering wheel and
the measured applied torque at the
steering column. This leads to a
more robust hands detection.
WARNING!
• Risk of accident despite steering
torque application of Active Blind
Spot Assist (ABSA).
• A course-correcting steering torque
application cannot always prevent a
collision.
• The driver is always required to
steer, brake or accelerate themself,
especially if ABSA warns or makes a
course correcting steer intervention.
• Always maintain a safe distance at
the sides.
• Steering torque application may be
interrupted at any time by counter
steering by the driver.
RCP - Rear Cross Path
Operation RCP operation is the same as described
in chapter "Blind Spot Assist - BSA". When ABSA is turned off from MTC+
"Controls" page, there will be no
visual or audible alerts from RCP
subsystem.
When ABSA is turned on with any
setting,RCP subsystem shall respond
with both visual and audible alerts
when a detected vehicle or object is
present. Whenever an audible alert is
requested, the radio (if on) is also
muted.
Right/left turn/hazard signal status is
ignored; the RCP status always
requests the chime.
System Temporarily
Unavailable The blind spot system will become
temporarily unavailable and the
instrument cluster display will show
the message “Blind Spot Alert
Temporarily Unavailable” when the
vehicle enters a radio quite zone
(example the areas around radio
telescopes).
The warning light on the outside
rear-view mirrors will be lit up and
stay lit until the vehicle exits the zone.
System Fault The ABSA system cannot properly
operate either due to a fault of its
components, or because the area onDriving
5
273

windshield where the forward-facing
camera is located or 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 do not use 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. Highway Assist – HAS
(optional, with ACC only) The Highway Assist (HAS) is a level 2
Autonomy system (in reference to
NHTSA standards) that is designed to
aid the driver in the steering,
acceleration, and braking functions of
the vehicle.
HAS is designed to only function on
highways or limited access freeways.
HAS centers the vehicle by controlling
the EPS system based off of lane line
information from the forward-facing
camera and data from the front radar
sensor.
HAS combines ACC and LKA to
manage the steering and speed of the
vehicle under specific conditions. The
conditions to engage HAS are listed in
the next paragraph. If a lane line cross
is imminent, the steering wheel will vibrate and a graphic will display on
the instrument cluster.
WARNING!
• In case the vehicle approaches a
curve that is too tight in relation to
the current speed the system will
disengage, therefore the driver must
be prepared to take over control of
the vehicle immediately at any time.
To avoid this situation it is important
that the vehicle speed is not set
higher than the current speed limit
of the road.
• Highway Assist (HAS) is a hands-on
feature! You must keep your hands
on the steering wheel at all times.
The HAS system will disengage and
ACC will cancel if your hands are
removed from the steering wheels
for a set amount of time.
• HAS is intended for use only on
highways or limited access freeways
with a fully attentive driver. When
using HAS, hold the steering wheel
and be aware of surrounding traffic
and road conditions. Always be
prepared to immediately take over
control of the vehicle from the HAS
system. Failure to follow theseDriving
5
274

instructions could result in serious
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
causing the
system to be unable to function as
intended. These include (but are not
limited to):
• Narrow, winding or curvy roads.
• Poor visibility (due to heavy rain,
snow, fog, etc.).
• Bright light (oncoming headlights or
direct sunlight) or shadows.
• Damage or obstruction caused by
mud, ice, snow, etc.
• A damaged or misaligned bumper.
• Interference from other equipment
that generates electromagnetic
waves. • Wet roads, roads covered or partially
covered by snow.
• Construction zones.
HAS Operation With ACC set (see “Adaptive Cruise
Crontrol – ACC” in this section), HAS
system activates by simply pressing the
button on the steering wheel.
Once the conditions are met, HAS will
engage.
CAUTION!
The Highway Assist (HAS) system may
take up to 5 seconds to engage once
all conditions are met.
The conditions for HAS to engage are
as
follows:
• HAS must be turned on or enabled.
NOTE:
In case of wet road or raining
conditions the function could be
disabled by the system in order to
minimize the risks.
• The vehicle must be on the highway
or limited access freeway.
• Adaptive Cruise Control (ACC) must
be engaged.
• Left and right visible lane lines. • Vehicle speed must be between 0 to
90 mph (0 and 145 km/h).
• No faults in the forward facing
camera, radar, EPS, or MTC+.
• Lane width between 3 to 4.6 yd (2.8
and 4.2 m).
• Turn signal not activated.
• No faults related to this system.
Speed Range of Use Speed mph (km/h)
Minimum 0 (0)
Engaged/activated
(with ACC engaged) 0 (0)
Engaged/activated
(with ACC not
engaged) 18 (30)
Maximum 90 (145)
• If set above the maximum speed,
HAS will not function after the
vehicle speed will reach the
maximum speed.
• If set below the maximum speed and
the ACC target speed is increased,
HAS will function up to the
maximum speed and then the system
will turn off automatically.
• When the ACC target speed is
reduce and speed is lower than theDriving
5
275

maximum speed, the system will start
automatically.
• If the ACC target speed is set under
the maximum speed, HAS is active
and vehicle speed increases above
the maximum speed due to slope,
HAS will continue to function.
HAS Monitoring on Instrument
Cluster HAS and the other ADAS systems
conditions can be monitored on
instrument cluster display by accessing
the “Driver Assist” page with the
buttons on the steering wheel (see
“Instrument Cluster” in section
“Dashboard Instruments and
Controls”).
The
symbol in grey indicates that
the HAS system is active, but not
engaged and is shown at the centre of
the TFT display when the “Driver
Assist” page is displayed. When exiting
the "Driver Assist" page, on TFT
display top left corner, the
grey
symbol will appear in the multiple
light of active ADAS systems. In addition to these symbols, on the
TFT top and bottom edge a coloured
glow may appear (further referred to
as "attention level colour"). Attention
level colour together with the outline
of the symbol
represent a further
indication of the system status. When exiting the “Driver Assist” page,
the attention level colour will always
be displayed until the system is
disabled by pressing the
button on
the steering wheel.
The HAS system uses sensors in the
steering wheel outer crown to detect
if the driver’s hands are on the
steering wheel. If the driver’s hands
are not detected on the steeringDriver Assist Page
Non-Driver Assist Page Driver Assist Page
Non-Driver Assist PageDriving

276

wheel, the instrument cluster will
display a series of warnings to alert
the driver to return their hands to the
steering wheel. There will also be
audible chimes. After a set amount of
time, HAS will cancel if the driver’s
hands are not returned to the steering
wheel.
When the system does not sense the
hands on the steering wheel for a few
seconds (3 – 5 seconds) or more (up to
10 seconds), it tries to draw the
attention of the driver by showing,
even when the display is not in the
"Driver Assist" page, the
symbol
with the figure of the hands in the
centre of the display. According to
such time frames, the system will
change the attention level colour,
silence the audio in the vehicle (if it is
active) and emit audible chimes to
invite the driver to take the control of
the vehicle again. This is the only way
to reengage the system.
Hands Detection on Steering
Wheel The sensors in the steering wheel
outer crown are able to detect the
presence of the hands on the steering
wheel. In order to be able to use the HAS
system, place your hands around the
steering wheel outer crown.
NOTE:
• The sensors are not able to detect
the presence of the hands on the
steering wheel areas covered in
wood, plastic bezels or carbon
inserts (where present).
HAS is deactivated if the steering
wheel is no longer being touched.
System Statuses The active status of the HAS system is
indicated by the green attention level
colour which is maintained even if the
driver releases his/her grip from the
steering wheel up to 3 seconds.
The yellow attention level colour
appears when the driver removes
his/her hands from the steering wheel for 3 to 5 seconds and the
symbol
with the figure of the hands will
occupy the whole central area of the
display.
The red attention level colour appears
when the driver releases his/her grip
from the steering wheel for 5 and up
to 10 seconds: in this case a single
audible chime is repeated until he/she Driver Assist Page
Non-Driver Assist PageDriving
5
277

will take the control of the vehicle
again.
The red attention level colour remains
even when the steering wheel is
released for more than 8 to 10
seconds. In this case, if you are
travelling at a speed above 25 mph
(40 km/h) a sequences of 3 audible
chimes will be emitted after 8 seconds and a message will inform the driver
that the HAS system has been
disengaged, instructing him/her to grip
the steering wheel again. The same
will happen after 10 seconds if you
travel at a speed below 25 mph
(40 km/h). Then the
symbol on TFT
display will become grey.
If the driver keeps his/her hands away
from the steering wheel (for more
than 8 to 10 seconds), also the ACC
system is deactivated (
white ACC
symbol on the display) and will have to
be reset. The aid of LKA system will be
disabled as well. In these cases the
display will not show the attention
level colour anymore and the vehicle
will be controlled by the driver only.
HAS Disengage To disengage HAS you can do any of
the following actions: • Press the
HAS enable button on
the steering wheel.
• Begin steering manually.
• Press brake pedal.
• Turn off ACC.
• Unbuckle the driver’s seat belt.
• Press ACC Gap button for two
seconds to enable CC system.
• Shift out of the (D) Drive gear.
• Enter an Autonomous Emergency
Braking (AEB) event (See chapter
"Forward Collision Warning - FCW"
in this section).
• Turn signal activated.
System Cancellation The HAS system will cancel (without
driver intervention) if either of the
following actions occur:
• Curve that is too tight.
• When leaving the grip of the hands
on the steering wheel.
• Vehicle exits the highway or limited
access freeway.
• Lane line markers aren’t detected by
the forward facing camera.
• Any ADAS system faults.
• ACC cancellation.
• Vehicle speed exceeds the maximum
limit.Driver Assist Page
Non-Driver Assist PageDriving
5
278

• Lateral accelerations exceeds the
limits.
NOTE:
• When HAS cancels, the symbol
will turn red then grey.
• The presence of the hands on the
steering wheel is detected by a logic
combination of a capacitive sensor
installed in the steering wheel and
the measured applied torque at the
steering column. This leads to a
more robust hands detection.
System Limitations HAS is unable to guide the vehicle
when the following conditions occur.
• Lane markings are not clear or
visibility is poor (i.e. heavy rain,
snow, fog, etc.).
• Obstructed, covered or damaged
forward-facing camera or sensor.
• When driving on hills or sharp
curves.
• When approaching toll booths.
• When the highway entrance or exit
is wider than 20 ft (6 meters).
• Bright light (ex. direct sunlight or
glare) facing the forward camera. WARNING!
Many unforeseen conditions can occur
that can affect the performance of
Highway Assist (HAS). Always keep
this in mind and drive attentively. It is
the drivers responsibility to keep
control of the vehicle at all times.
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.Traffic Sign Assist – TSA
(optional) TSA detects traffic signs through the
use of a forward-facing digital camera
mounted on windshield, behind the
rear-view mirror. TSA assists the driver
by displaying on the instrument
cluster detected speed limits and
traffic signs with a restriction
indicated by an additional sign (e.g. in
snow conditions). TSA also uses the
data of the navigation system, in
order to provide information to the
driver in all cases in which the camera
is not able to detect the traffic signs
that are present on the road where
the car is travelling.
Some examples of these are: due to
low visibility, light reflection, damaged
traffic signs, traffic signs in wrong
position like rotated or fallen poles.
NOTE:
• Overtaking restriction signs are not
displayed by the TSA system.
• TSA provides a visual warning to the
driver when he/she unintentionally
reaches the maximum speed limit
allowed or when it exceeds the set
“Sensitivity” value.

109. Grades B and A represent higher
levels of performance on the
laboratory test wheel, than the
minimum required by law.
WARNING!
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, under-inflation, or excessive
loading, either separately or in
combination, can cause heat buildup
and possible tire failure.
Tire Pressure Proper tire inflation pressure is
essential for safety and best
performance of your vehicle. The tire
pressure monitoring system “TPMS”
setup on the vehicle (see “Tire Pressure
Monitoring System” in this section)
may alert the driver about insufficient
tire pressure even though the driver is
responsible for regularly checking the
tire pressure.
Radial tires fitted on the vehicle may
look properly inflated even when they
actually are under inflated. Do not
make a visual judgment when
determining proper inflation. Three primary driving aspects are
affected by improper tire pressure:
Safety
WARNING!
• Improperly inflated tires can be
dangerous.
• Under-inflation increases tire flexing
and can result in tire overheating.
• Over-inflation reduces a tire's ability
to cushion shock. Objects on the
road and potholes can cause damage
that results in tire failure.
• Over-inflated or under-inflated tires
can affect vehicle handling and can
fail suddenly, resulting in loss of
vehicle control.
• Unequal tire pressures can cause
steering problems.
• Unequal tire pressures from one side
of the vehicle to the other can cause
the vehicle to drift to the right or
left.
• Always drive with each tire inflated
to the recommended cold tire
inflation pressure.
Economy
Improper
inflation pressures may cause
uneven wear patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life
resulting in a need for earlier tire
replacement. Under-inflation also
increases tire rolling resistance
resulting in higher fuel consumption.
Ride comfort and vehicle stability
Proper tire inflation contributes to a
comfortable ride. Over-inflation
produces a jarring and uncomfortable
ride.
Tire Pressure Checkup The proper cold tire inflation pressure
is indicated on the driver's side rear
door pillar and on the table “Tire
Inflation Pressure” in section “Features
and Specifications”.
Inflation pressure specified on the
table always refers to “cold tire
inflation pressure”. Cold tire inflation
pressure is defined as the tire pressure
after the vehicle has not been driven
for at least three hours, or driven less
than 1 mi (1.6 km) after a three hour
period.
Check tire pressures more often in case
of significant outside temperature
changes, as tire pressure varies
according to temperature changes.
The pressure should be checked and if
necessary adjusted; tire wear andDriving

replacement tires may adversely affect
the safety, handling, and ride of your
vehicle.
Your Authorized Maserati Dealer is
available to provide suggestions as to
the types of tires most suited to the
use foreseen by the Customer.
WARNING!
• Do not use a tire, wheel size or
rating other than that specified for
your vehicle. Some combinations of
unapproved tires and wheels may
change suspension dimensions and
performance characteristics,
resulting in altered steering,
handling, and braking operations of
the vehicle. This can cause
unpredictable handling and stress to
steering and suspension
components. Use only the tire and
wheel sizes with load ratings
appointed for your vehicle.
• Never use a tire with a smaller load
index or capacity, other than what
was originally equipped on your
vehicle. Using a tire with a smaller
load index could result in tire
overloading and failure.
• Always check the maximum speed
rating on the tire sidewall on any tire on the vehicle.
• Never exceed the maximum speed
rating of the tires. Risk of accident
and serious personal injury due to
excessive speed.
• Failure to equip your vehicle with
tires having adequate speed
capability can result in tire failure.
CAUTION!
Replacing original tires with tires of a
different size may result in false
speedometer and odometer readings.
Winter Tires These tires are specially designed for
driving on snow and ice and are fitted
to replace the ones supplied with the
vehicle. Winter or all-season tires can
be identified by the M+S (Mud &
Snow) or 3PMSF (3 Peaks Mountain
Snow Flake) designation on the tire
sidewall.
Before mounting winter tires, contact
an Authorized Maserati Dealer to
receive the technical information
necessary to advise you on wheel and
tire compatibility.
As to the type of tires to use, inflation
pressures and winter tires specifications, carefully follow the
indications as reported in the
“Technical Data” and “Tire Inflation
Pressure” chapters in section “Features
and Specifications”.
WARNING!
The standard tires profile and rubber
mixture are optimized for wet and dry
driving conditions. Standard tires may
not prove favorable for snow
conditions.
NOTE:
Snow
tires should have the same load
capacity as original equipment tires
and should be mounted on all four
wheels.
Snow Chains Maserati approved traction devices (or
snow chains) may be used to improve
traction on compacted snow in heavy
snow conditions.
The use of snow chains is specified by
local regulations of each country.
Use snow chains of reduced
dimensions, with a maximum
projection of 0.23 in (6 mm) beyond
the tire tread.Driving
