ESP MASERATI QUATTROPORTE 2019 Repair Manual

Setting options are described in the
following paragraph.
When FCW status for some reason
changes to off, the corresponding
amber warning light on instrument
cluster will light on.
This warning light informs the driver
that FCW is disabled. This warning
light will light even when the
activation of another driver assistance
feature or drive mode (example:
(ESC OFF)) disables the FCW. NOTE:
The FCW system setting is kept in
memory from one key cycle to the
next.
Changing FCW Sensitivity and
Active Braking The default status of FCW Sensitivity is
the “Medium” setting. When the
active braking function (“Forward
Collision Warning Active Braking”)
setting is on, the system warns you of
a possible collision with the vehicle in
front of you when you are farther
away and it applies limited braking.
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 be
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 fromDriving

270

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.
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.
Lane Keeping Assist - LKA
(optional, with ACC only) This system was designed especially
for highway or freeway driving, to
reduce the risk that the vehicle, under
particular circumstances, accidentally
departs from the lane in use. When
this happens, graphic instructions on
instrument cluster display together
with steering torque application and
steering wheel vibration (depending
on the distance to the line) warn the
driver that the vehicle is going out of
the lane initiates a steering maneuver
to try to prevent the lane exit.
To detect lane lines, the system uses
the forward-facing camera behind the
rear-view mirror, which is the same
one used also by the lighting system
to manage the automatic high beams.
The logic core is in the front radar.
LKA system remembers the condition
it was in before turning off the
vehicle.
Refer to “MTC+ "Controls" Screen” in
section “Dashboard Instruments and
Controls” for further information.Driving

NOTE:
In case of wet road or raining
conditions the function could be
disabled by the system in order to
minimize the risks.
Speed Range of Use Speed mph (km/h)
Minimum 37 (60)
Engaged/activated 37 (60)
Maximum 112 (180)
Customized Settings LKA is configurable by the driver in
order to maximize its efficiency based
on the driver driving style and the
expectation of the system, reducing at
the same time the possible
invasiveness.
Entering "Controls" page on MTC+
display the driver can see the current
setting beside the "Lane Keeping
Assist" soft-key.
Touching “Lane Keeping Assist”
soft-key can disable or enable the
system. Touching the soft-key on the side the
driver can change the setting.
Driver warnings can be only "Visual"
or "Visual & Haptic" (default mode).
System response can be set to "Early",
"Medium" (default mode) or "Late".
System reaction force can be set to
"Low", "Medium" (default mode) or
"High".
Meanings of Settings
• "Visual" only: the system will not
request any steering torque/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 directional 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.Driving

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 for only a 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.
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 lanes 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, only in limited cases
and for a limited time, 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 the transition from
LKA to Active Blind Spot Assist (ABSA)
(if this latter is on and properly
configured).
Function Description and
Operating Mode The 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 enabled 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 reason, 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
properly estimate the lane);Driving
5
273

• 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/her to properly handle
the situation;
• Yellow flashing line: the graphic is
shown whenever the system detects
a very imminent lane departure;
torque and steering vibration can be
added to this warning 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 these screens 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.

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 Page Driving

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.

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 Alert 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

Highly dynamic behaviours, driving on
the lane boundary, 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 road must respect some
characteristics such as minimum-
maximum width, lane clearly defined
by two lane boundaries and only in
limited case for a limited time at least
one.
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 recognise
as valid lane boundaries also other
types (for example road edges, curbs,
etc..). Speed Range of Use Speed mph (km/h)

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".Driving

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 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.
