wheel MASERATI GHIBLI 2019 Workshop Manual

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. Do not pump
brakes.
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 should 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 increases gradually to a
safe value.
During this event, the ETC light
indicator will illuminate. The system
exits from this strategy when the
accelerator pedal is completely
released.
Hill Start Assist (HSA) The HSA system is designed to assist
the driver when starting a vehicle
uphill. HSA will maintain the level of
brake pressure applied for a short
period of time also after releasing the
brake pedal.Driving

Electronic Cruise Control The electronic Cruise Control (CC)
enables the driver to maintain the
desired vehicle speed without pressing
the accelerator pedal, reducing driving
fatigue on highways, especially long
trips, as the set speed is automatically
maintained. A firm press on the
accelerator pedal or the braking pedal
will temporarily deactivate the cruise
control function.
CAUTION!
The device can only be switched on at
speeds exceeding 18 mph (30 km/h)
and it switches off automatically when
the brake pedal or the accelerator
pedal is pressed.
WARNING!
The Cruise Control function must only
be activated when traffic and the
route permit a constant speed to be
maintained safely for a sufficiently
long distance. Controls The electronic Cruise Control controls
are located on the left side of the
steering wheel.
Control configuration depends on
which driver assist systems are installed
to the vehicle.
In the standard configuration there is
a specific button to enable and disable
the CC.
In the optional configuration, there is
no specific button to enable and
disable the CC, since the driver uses
the ACC control buttons. Control buttons have the following
functions:
Standard Configuration
ON/OFF button to
engage/disengage CC
system.
Optional Configuration
Press ACC Gap button and
hold it down for 2 seconds
to enable the CC system.

could cause an incorrect assessment
of the required safety distance.
It is recommended to disable the ACC
system in the following instances:
• When driving in the fog, heavy rain,
heavy snow, slush, heavy traffic and
similar complex situations such as
highway construction zones.
• When entering a junction lane or a
slip road to leave the highway; when
driving on narrow, icy, snowy,
slippery roads, or on steep uphill and
downhill roads.
• When circumstances do not allow to
drive safely at constant speed.
Displayed information Adaptive Cruise Control (ACC)
condition, as well as the LKA and HAS
status, is displayed on instrument
cluster after selecting “Driver Assist”
menu (see paragraph “TFT Display:
Menus and Settings" under
“Instrument Cluster” in section
“Dashboard Instruments and
Controls”).
Displayed information depends on
system status: ready, set, temporarily
cancelled or override.
Apart from the image at the center of
the display, CC, ACC, LKA and HAS
systems status is represented by icons at the top left and right. These icons
remain displayed even when exiting
the "Driver Assist" screen.
The vehicle(s) and horizontal bars
represent the ACC status as ready
(white) or with sensed vehicle ahead
(green); the white, grey or yellow lines
represent the LKA and HAS systems.
The ACC screen can be displayed any
time driver changes system status or
settings. After 5 seconds of ACC
inactivity, the display goes back to last
screen.
ACC Controls and Activation

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.

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

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

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

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. 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..).Driving

• 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.
