2019 MASERATI QUATTROPORTE sensor

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.
RCP - Rear Cross Path
Operation RCP operation is the same as described
in chapter "Blind Spot Assist - BSA".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
5
284

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

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 and overall conditions should also be
checked monthly. Tire pressures
change by approximately 1 PSI (0.07
bar) per 12°F (7°C) of air temperature
change. Keep this in mind when
checking tire pressure inside a garage,
especially in winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature =
32°F (0°C) then the cold tire inflation
pressure should be increased by 3 PSI
(0.21 bar) for every 12°F (7°C) for this
outside temperature condition.
Tire pressure may increase from 2 to 6
PSI (0.13 to 0.4 bar) during operation.
DO NOT reduce this normal pressure
build-up or your tire pressure will be
too low. After inspecting or adjusting
the tire pressure, always reinstall the
valve stem cap. This will prevent
moisture and dirt from entering the
valve stem, which could damage the
valve stem and the TPMS sensor
connected to it.
Tread Wear Indicators Tread wear indicators are in the
original equipment tires to help you
determine when your tires should be
replaced.
These indicators are molded into the
bottom of the tread grooves.Driving
5
297

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

WARNING!
The TPMS warns the driver that the
tire pressure has decreased. This
warning does not exempt the driver
from periodically checking the tires
and from complying with the
prescribed tire pressure levels.
CAUTION!
• The TPMS has been optimized for
the original equipment tires and
wheels. TPMS pressures and
warning have been established for
the tire size equipped on your
vehicle. Undesirable system
operation or sensor damage may
occur when using replacement
equipment that is not of the same
size, type, and/or style. Aftermarket
wheels can cause sensor damage. Do not use aftermarket tire sealants
or balance beads if your vehicle is
equipped with a TPMS, as damage
to the sensors may result.
• The system can temporarily
experience radio-electric
interference emitted by devices
using similar frequencies.
• After inspecting or adjusting the tire
pressure, always reinstall the valve
stem cap. This will prevent moisture
and dirt from entering the valve
stem and damage the TPMS internal
sensor.
NOTE:
• Driving
on a significantly
underinflated tire causes the tire to
overheat and may lead to tire
failure. Under-inflation also reduces
fuel efficiency and tire tread life, and
may affect the vehicle’s handling and
stopping ability.
• The TPMS is not a substitute for
proper tire maintenance, and it is
the driver’s responsibility to maintain
correct tire pressure using an
accurate tire pressure gage, even if
under-inflation has not reached the
level to trigger illumination of the
TPMS light
.
• Seasonal temperature changes will
affect tire pressure, and the TPMS will monitor the actual tire pressure
in the tire.
Premium System The TPMS system uses wireless
technology with wheel rim mounted
electronic sensors to monitor tire
pressure levels. Sensors mounted to
each wheel as part of the valve stem
transmit tire pressure readings to the
receiver module.
The TPMS consists of the following
components:
• receiver module;
• four TPMS sensors;
• various TPMS messages, which
display on the instrument cluster;
• warning light
.
Tire Pressure Low Warning
The TPMS light will illuminate in
the instrument cluster and an acoustic
signal will notify that tire pressure is
low in one or more of the four tires.Driving
5
301

The instrument cluster will also display
a screenshot reporting the pressure
values of each tire with flashing low
pressure value.
Should this occur, you should stop as
soon as possible and inflate the tire/s
with the low pressure (the one/s
flashing in the instrument cluster
graphic) to the recommended cold
pressure inflation value. Once the
system receives the updated tire
pressure value, the system will automatically update, the graphic
display in the instrument cluster will
stop flashing, and the TPMS light
will turn off. The vehicle may need
to be driven for up to 20 minutes
above 15 mph (24 km/h) in order for
the TPMS to acquire and process the
updated information.
Tire Pressure System Fault
If a system fault is detected, the TPMS
light
will flash for 75 seconds and
then remain lit followed by a beeping
sound. Therewith, the instrument
cluster will display a "Service Tire
Pressure System" message for a
minimum of five seconds and then
display dashes (--) in place of the
pressure value to indicate which sensor
is ineffective.
If the ignition switch is cycled, the
sequence will repeat, in case the
system fault still persists. If the system
fault no longer exists, the TPMS light
will no longer flash, and the
"Service Tire Pressure System" message
will no longer be displayed, and a
pressure value will be displayed in
place of the dashes.
A system fault can occur due to any of
the following:
• Signal interference due to electronic
devices or driving next to facilities emitting the same radio frequencies
as the TPMS sensors.
• Installing aftermarket window
tinting that contains materials that
may block radio wave signals.
• Accumulation of snow or ice around
the wheels or wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with
TPMS sensors.
The instrument cluster will also display
a "Service Tire Pressure System"
message for a minimum of five
seconds when a system fault related to
an incorrect sensor location fault is
detected. In this case, the "Service Tire
Pressure System" message is then
followed by a graphic display with
pressure values still shown. This
indicates that the pressure values are
still being received from the TPMS
sensors but they may not be located in
the correct vehicle position. The system
still needs to be serviced as long as the
"Service Tire Pressure System" message
is displayed.Driving
