sensor MASERATI LEVANTE 2019 Service Manual

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
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 from
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.
• When in “CORSA” mode (TROFEO
version only), the FCW feature is
deactivated.

The icons that represent the status of
the ADAS systems remain displayed
even when you exit the “Driver Assist”
screen.
System Limitations Because of physical limits, in order to
properly operate, the system 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, etc.).
NOTE:
• 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 when hands
are actually on the steering wheel (at
least one).
• 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).
Sharp turns, slopes and change in
slopes, poor lane boundaries, as well
as construction areas and all the
scenario 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 fault, but not
explicitly indicated here may also prevent/interrupt the system
intervention.
WARNING!
If the driver fails to adapt his/her
driving style, Lane Keeping Assist
(LKA) can neither reduce the risk of an
accident nor override the laws of
physics. It cannot take into account
road, weather or traffic conditions.
Active LKA is only an aid. Driver is
always responsible for the distance to
the vehicle in front, for vehicle speed,
for braking in good time and for
staying in lane.
System in Fault When the LKA cannot properly
operate due to a fault of its
components or because the windshield
in front of the forward facing camera
is dirty, the amber light and/or the
corresponding message will be
displayed.Non-Driver Assist PageDriving

If message suggestion does not allow
fixing the fault, do not use the system
and have the vehicle inspected at the
Authorized Maserati Dealer .

"Services" section on the website
www.maserati.com. Blind Spot Assist – BSA
(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
5
305

The BSA system monitors the detection
zones on both sides of the vehicle
when the vehicle speed reaches
approximately 6 mph (10 km/h) or
higher and will alert the driver of
vehicles in these areas.
WARNING!
• The BSA system does NOT alert the
driver about rapidly approaching
vehicles that are outside the
detection zones.
• The BSA might alert the driver too
late especially in case of rapidly
approaching vehicles.
WARNING!
Risk of accident despite Blind Spot
Assist (BSA).
BSA does not detect/react to the
following:
• Overtaking vehicles close on the
side, placing them in the blind spot
area. As a result, BSA may neither
give warnings nor intervene in such
situations. • Always pay attention to the traffic
situation and maintain a safe
distance at the side of the vehicle.
NOTE:
If
your vehicle has
experienced any
damage in the area where the sensor
is located, even if the fascia is not
damaged, the sensor may have
become misaligned. Take your vehicle
at an Authorized Maserati Dealer to
verify sensor alignment. Having a
sensor that is misaligned will result in
the BSA not operating to specification.
The area on the rear bumper fascia
where the radar sensors are located
must remain free of snow, ice, and
dirt/road contamination so that the
BSA system can function properly. Do
not cover or block the area of the rear
bumper fascia where the radar sensors
are located with foreign objects
(bumper stickers, spoilers, bicycle racks,
etc.).
The BSA system notifies the driver of
vehicles or objects in the detection
zones by illuminating the BSA warning
light located in the outside mirrors in
addition to sounding an audible
(chime) alert and reducing the radio
volume (if the radio is on). Refer to “BSA and RCP Setting” in this chapter
for further information.
The BSA system monitors the detection
zone from three different entry points
(side, rear, overtaking traffic) while
driving to see if an alert is necessary.
The BSA system will issue an alert
whenever a vehicle enters any one
detection zone as outlined below.

(Continued)
• The BSA system is not designed to
detect pedestrians, cyclists, or
animals.
• Even if your vehicle is equipped with
the BSA system, always check your
vehicle’s outside and rearview
mirrors for any vehicles approaching
from behind or overtaking.
• Use your turn signal before changing
lanes.
RCP - Rear Cross Path The Rear Cross Path (RCP) feature is
intended to aid the drivers when gear
in reverse of parking spaces where
their vision of oncoming vehicles may
be blocked.
The RCP system monitors the rear
detection zones on both sides of the
vehicle. Using sensors located on either
side of the rear bumper, it detects any
vehicles or objects that are moving
toward the side of the vehicle with a
minimum speed of approximately 1 to
2 mph (1 km/h to 3 km/h) to a
maximum of approximately 10 mph
(16 km/h), such as in parking lot
situations. NOTE:
In a parking lot situation, oncoming
vehicles can be obscured by vehicles
parked on either side. If the sensors
are blocked by other structures or
vehicles, the system will not be able to
alert the driver.
Proceed slowly and cautiously out of
the parking space until the rear end of
the vehicle is moderately exposed.
The RCP system will then have a clear
view of the cross traffic. If an
oncoming vehicle is detected, the RCP
system will alert the driver using both
the visual and audible alarms. If the
radio is on, it will also reduce the radio
volume.
WARNING!
RCP is not a Back Up Aid system. More specifically, it is intended to be used to
help a driver detect an oncoming
vehicle in a parking lot situation.
Drivers must be careful when backing
up, even when using RCP. Always
check carefully behind your vehicle,
look behind you, and be sure to check
for pedestrians, animals, other
vehicles, obstructions, and blind spots
before backing up. Failure to do so can
result in serious injury or death.
BSA and RCP Setting Setting modes can be selected from
the MTC+ System.

BSA in Visual Mode
When operating in “Visual” mode, the
BSA system will provide a visual alert
in the appropriate side view mirror
when it detects a vehicle or an object
in the detection areas monitored by its
sensors: depending on the status of
the relative turn indicator, the
warning light can be fixed or flashing.
However, when the system is
operating in RCP mode, it will respond
with both visual and audible alerts
when an oncoming vehicle or an
object approaching the rear end side
of the vehicle is detected.
Whenever an audible alert is
requested, the radio is muted (if the
radio is on).
BSA in Visual and Acoustic Mode
When operating in “Visual & Acoustic”
mode, the BSA system will provide a
visual alert in the appropriate side
view mirror based on a detected
vehicle or object. If the turn signal is then activated, and
it corresponds to an alert present on
that side of the vehicle, an audible
chime will also be sounded: in the
same moment the warning light will
start flashing.
Whenever a turn signal and detected
vehicle or object are present on the
same side at the same time, both the
visual and audio alerts will be issued.
In addition to the audible alert, the
radio volume will be reduced (if the
radio is on).
NOTE:
If the hazard flashers are on, the BSA
system will issue the appropriate visual
alert only.
When the system is in RCP mode, the
system 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.
Blind Spot Assist Off
When this function is turned off from
the MTC+, there will be no visual or
audible alerts from either the BSA or
RCP subsystems.
NOTE:
The BSA 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.
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.Driving

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.
Highly dynamic behaviours, driving on
the lane boundary, off course willDriving

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. • ABSA “Strength": it tunes the
steering torque value to have a
stronger or weaker trajectory
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

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 in 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
5
313

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 steering 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 wheelDriver Assist Page
