www.maserati.com. Blind Spot Assist (without
ACC) BSA System Operation The Blind Spot Assist (BSA) system uses
two radar-based sensors, located inside
the rear bumper fascia, to detect
highway licensable vehicles (cars,
buses, motorbikes, etc.) that enter the
blind spot zones from the
rear/front/side of the vehicle.
The example shown in the figure
highlights the blind spots on either
side of the vehicle when oncoming
traffic is approaching from behind.
When the vehicle is started, the BSA
warning light will momentarily
illuminate in both outside rear view
mirrors to let the driver know that the
system is operational and on. The BSA
system sensors operate when the vehicle is in any forward gear and
enters standby mode when the
transmission is in (P) Park.
The BSA detection zone shown in
figure covers approximately one lane
on both sides of the vehicle
(approximately 11 ft or 3.3 m). The
blind spot area extends from
immediately behind the exterior
rear-view mirrors up to about 23 ft (7
m) behind the rear bumper.Driving

Entering from the Rear
The alert will turn on when the
vehicles that come up from behind
your vehicle on either side and enter
the rear detection zone with a relative
speed of more than 27 mph (43 km/h).
Overtaking Traffic
The figures show the vehicle
approaching (A) and passing (O)
another vehicle in the overtaking lane.
If you pass another vehicle slowly, the
vehicle remains in the blind spot for
approximately 2 seconds, the BSA
warning light in the outside mirror will
illuminate after 1.5 seconds.
If the difference in speed between the
two vehicles is greater, the warning
light will not illuminate. Other Cases
The BSA system is not designed to
issue an alert on stationary objects
such as guardrails, posts, walls, foliage
heaps, berms, etc. However,
occasionally the system may alert on
such objects. This is normal operation
and your vehicle does not require
service. The BSA system will not alert you of
objects that are traveling in the
opposite direction of the vehicle in
adjacent lanes.
WARNING!
• The BSA system is only an aid to
help detect vehicles in the blind spot
zones.
• The BSA system is not designed toDriving

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 do not use the system
and have the vehicle inspected at an
Authorized Maserati Dealer .
Radar Device - Regulatory
Information The “Regulatory Information” for all

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's direction 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.Driving

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 on 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 .

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 willDriving

• 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. • 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.

Department of Transportation
Uniform Tire Quality Grades The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by
the tire's manufacturer in each
category is shown on the sidewall of
the tires on your vehicle.
All passenger car tires must conform to
Federal safety requirements in
addition to these grades.
Treadwear
The Treadwear grade is a comparative
rating, based on the wear rate of the
tire when tested under controlled
conditions on a specified government
test course. For example, a tire graded
150 would wear one and one-half
times as well on the government
course as a tire graded 100. The
relative performance of tires depends
upon the actual conditions of their
use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
Traction Grades
The Traction grades, from highest to
lowest, are AAA, A, B, and C. These grades represent the tire's ability to
stop on wet pavement, as measured
under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
WARNING!
The traction grade assigned to this tire
is based on straight-ahead braking
traction tests, and does not include
acceleration, cornering, hydroplaning,
or peak traction characteristics.
Temperature Grades
The
temperature grades are A (the
highest), B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat,
when tested under controlled
conditions on a specified indoor
laboratory test wheel. Sustained high
temperature can cause the material of
the tire to degenerate and reduce tire
life, and excessive temperature can
lead to sudden tire failure. The grade
C corresponds to a level of
performance, which all passenger car
tires must meet under the Federal
Motor Vehicle Safety Standard No.
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:Driving

296

When the tread is worn to one of the
tread wear indicators, the tire should
be replaced.
WARNING!
The wet performance (aquaplaning
resistance) will decrease
proportionally to the thickness of the
tread.
Tires Durability The service life of a tire depends on
various factors including, but not
limited to:
• driving style;
• tire pressure;
• distance driven.
WARNING!
Tires and the spare tire (if equipped)
should be replaced after six years,
regardless of the remaining tread.
Failure to follow this warning could
result in tire failure. Replacement Tires NOTE:
In order to maintain high performance
and safety level under all driving
conditions, Maserati strongly
recommends to use tires equivalent to
the originals in size, quality and
performance when replacement is
needed.
For the size designation of your tire
see the label on the driver's side rear
door pillar or see table “Wheels” in
section “Features and Specifications”.
The “Load Index” and “Speed Symbol”
for your tire will be found on the
original equipment tire sidewall.
NOTE:
Maserati recommends Maserati
Genuine Tires marked with “MGT”
logo specifically designed for its
models.
It is recommended to replace the two
front tires or two rear tires as a pair.
Replacing just one tire can seriously
affect your vehicle’s handling.
If you ever replace a wheel assembly,
make sure that the wheel’s
specifications (valve, TPMS sensor and
tire) match those of the original
wheels. Failure to use equivalent 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 anyDriving
