2019 MASERATI QUATTROPORTE display

Push the ON/OFF button a second time
and release to turn the system off. A
pop-up message is displayed for 2
seconds to indicate that ACC was
disabled.
WARNING!
Leaving the Adaptive Cruise Control
(ACC) system on when not in use is
dangerous. You could accidentally
activate the system or cause it to go faster than you want. Always leave
the system off when you are not
using it.
Setting the Speed When the vehicle reaches the required
speed, press down and release the
multifunction control (SET -). The
display will show set speed
corresponding to vehicle current one.
Speed value will be indicated below
the
green symbol and above the
distance bars, in the center of the
display.
Remove foot from accelerator pedal
and vehicle will continue at set speed.
Driver Override If the driver accelerates beyond the set
speed or faster than the car would do
with ACC engaged, the set speed
below the
green light will blink and the time gap bars will vanish to
indicate that in this condition the
system cannot control the distance
between vehicle and sensed vehicle
ahead. Vehicle speed will be
determined only by the accelerator
pedal position.
Changing Speed Setting Once speed is set, driver can increase
or decrease it by respectively pressing
multifunction control up (RES +) or
down (SET -). Speed can be increased
or decreased in two ways:
• Pressing control once, set speed will
increase or decrease by one unit
corresponding to 1 mph (1 km/h).
• Hold the control to increase or
decrease set speed by 5 mph
(10 km/h) at a time.
NOTE:
• When pressing the multifunction
control up (RES +) or down (SET -),
the new set speed will be the current
speed of the vehicle.
• When using (SET -) control to
decelerate, if the engine braking
power does not slow down the
vehicle sufficiently to reach the set
speed, the brake system will
automatically slow down the vehicle.

• The ACC system applies the brake
down to a full stop when following a
target vehicle. If an ACC host vehicle
follows a target vehicle to a
standstill, after a two or three second
delay, the system will not be able to
resume driving the car
autonomously. At this point it is
necessary for the driver to manually
reengage the system by either using
the multifunction control (press SET-
or RES+) or by pressing the
accelerator pedal (see “ACC
Operation Before and During Stop”
in this chapter).
• The ACC system maintains set speed
when driving up hill and down hill.
However, a slight speed change on
moderate hills is normal. In addition,
downshifting may occur while
climbing uphill or descending
downhill. This is normal operation
and necessary to maintain set speed.
When driving uphill and downhill,
the ACC system will cancel if the
braking temperature exceeds normal
range.
Temporary Deactivation A soft tap on the brake pedal, pushing
the multifunction control (CANC), or normal brake pressure while slowing
the vehicle will temporarily deactivate
the ACC without erasing the set speed
memory. The
white light will appear
on the display with below the set
speed.
Conditions for Disabling and
Deactivation Besides the cases specified in the
previous paragraph, the following
conditions will disable the system:
• Anti-Lock Brake (ABS) kicks in.
• Transmission lever is not in D (Drive).
• The Electronic Stability Control and
the Traction Control System (ESC/TCS)
activate.
• Vehicle parking brake is operated.
• The driver safety belt is unbuckled at
low speed.
• The driver door is ajar at low speed.
• The driver disabled the ESC using the
(ESC OFF) button on central
console.
• The road is too steep both uphill and
downhill at low speed.
The system is deactivated and set
speed is deleted from system memory,
if the ACC ON/OFF button is pressed or
if ignition device is turned to OFF .Resuming Speed If a speed setting is stored in system
memory, press the multifunction
control (RES +) up and take foot off
the accelerator pedal. The last set
speed will be displayed.
WARNING!
The resume function should be used
only when road and traffic conditions
allow it. Resuming a too high or too
low speed for current traffic and road
conditions could cause a harsh vehicle
acceleration or deceleration which
could increase the risk of collisions
and death or serious injury.
Setting the ACC Gap The specified ACC gap can be set by
varying the distance setting among the
four possible options identified by the
number of horizontal bars:
• Maximum (longest) distance: 4 bars.
• Long distance: 3 bars (default
distance).
• Medium distance: 2 bars.
• Short distance: 1 bar.
Using this distance setting and the
vehicle speed, ACC calculates and sets
the gap to the vehicle ahead.Driving
5
262

If system does not detect the presence
of any vehicles ahead, only the bars
referred to set distance will be
displayed.
When system detects the presence of a
vehicle ahead, it is displayed in front
of the bars (see example in the figure).
To increase or decrease the number of
bars, corresponding to the gap from vehicle ahead, press and release the
distance setting button.
Each press and release of the button
changes the gap starting from 3 bars
(default distance) and moving in a
sequential way towards the minimum
distance: 3 → 2 → 1 → 4 → 3 → 2 → 1 → 4 and so
on.
If there is no vehicle ahead, the
vehicle will maintain the set speed. If a
slower moving vehicle is detected in
the same lane, the system displays the
target vehicle icon before the bars.
From that moment, the system adjusts
the vehicle speed automatically to
maintain the distance setting,
regardless of the set speed.
The vehicle will then maintain the set
distance until:
• The vehicle ahead accelerates to a
speed above the set speed. • The vehicle ahead moves out of the
lane or view of the sensor.
• The distance setting is changed.
• The driver disables the system.
The maximum braking applied by ACC
is limited; however, the driver can
always apply the brakes manually, if
necessary. Obviously, any time the ACC
system automatically operates the
brakes, the brake lights will turn on as
if the driver was braking.
A Proximity Warning on display will
alert the driver if ACC predicts that its
maximum braking level is not
sufficient to maintain the set distance.
If this occurs, a visual alert will flash
on the display and a chime will sound
while ACC continues to apply its
maximum braking capacity.Driver Assist Page

NOTE:
The displayed warning is a warning for
the driver to take action and does not
necessarily mean that the Forward
Collision Warning (FCW) system is
applying the brakes autonomously.
Overtake Aid When driving with ACC engaged and
following a target vehicle, the system
will provide an additional acceleration
to assist in passing vehicles in front.
This additional acceleration is
triggered when the driver utilizes the
left turn signal to start overtaking. In
locations with left hand drive traffic,
overtake aid is active only when
passing on the left hand side of the
target vehicle.
When a vehicle goes from a location
with left hand drive traffic to a
location with right hand drive traffic,
the ACC system will automatically
detect traffic direction. In this
condition, overtake aid is active only
when passing on the right side of the
target vehicle. This additional
acceleration is triggered when the
driver utilizes the right turn signal to
start overtaking. In this condition the
ACC system will no longer provide
overtake aid on the left side until it determines that the vehicle has moved
back to a location with left hand drive.
ACC Operation Before and
During Stop If an ACC host vehicle follows a target
vehicle to a standstill, after two or
three seconds the system will not be
able to resume driving the car
autonomously. In this condition, TFT
displays an instruction message pop up
for 5 seconds.
When the ACC system brings the
vehicle to a standstill while following a
target vehicle, the brakes are released
after two-three seconds after the stop
and at the same time the system
inserts the parking brake. When
parking brake engages the ACC
deactivates going to ready state.
At this point the driver must reengage
the system acting on the multifunction
control (RES + or SET -) or alternatively
on the accelerator pedal. While ACC
with Stop is holding your vehicle at a
standstill, if the driver unbuckles the
seatbelt or opens the door, the ESC
system will activate the EPB. During
standstill, ACC system monitors the
occupant detection signals: if the
driver's seatbelt becomes unbuckled,
the ACC system shall be cancelled
when the EPB is applied. WARNING!
• When the ACC system is resumed,
the driver must ensure that there are
no pedestrians, vehicles or objects in
the path of the vehicle. Failure to
follow these warnings can result in a
collision and death or serious
personal injury.
• During the automatic stopping
behind a vehicle in some rare cases it
may happen that the system does
not recognize the rearmost point of
the vehicle ahead but a target under
the vehicle ahead (e.g. the back axis
of a truck with a high loading edge
or a bumper of a vehicle although
overhanging load is hanging over
the vehicle’s rear). In these cases the
system cannot guarantee the
appropriate stopping distance
leading to collision in the worst case.
For this reason the driver has to be
attentive and ready to brake during
automatic stops.Driving

Display Warnings and
Maintenance of ACC and FCW
Systems Wipe Front Radar Sensor Warning
This warning will display and a signal
will indicate when conditions
temporarily limit system performance
due to sensor poor or failed signal
reception. This most often occurs at
times of poor visibility, such as in snow
or heavy rain. The ACC and FCW
systems may also become temporarily
blinded due to obstructions, such as
mud, dirt or ice on the radar sensor. In
these cases, the system will be
disabled.
This message can sometimes be
displayed while driving in highly
reflective areas (i.e. tunnels with
reflective tiles, or ice and snow). The
ACC and FCW systems will recover
operation after the vehicle has left
these areas. Under rare conditions,
when the radar is not tracking any
vehicles or objects in its path this
warning may temporarily occur.
If weather conditions are not a factor,
the driver should examine the sensor.
It may require cleaning or removal of
an obstruction. The sensor is located in
the center of the front grille, behind
the Maserati trident. To keep the ACC System operating
properly, it is important to note the
following maintenance items:
• Always keep the sensor clean.
Carefully wipe the sensor lens with a
soft cloth. Be cautious not to
damage it.
• Do not remove any screws from the
sensor. Doing so could cause an ACC
system malfunction or failure and
require a sensor realignment.
• If the sensor or front end of the
vehicle is damaged due to a collision,
see your authorized dealer for
service.
• Do not attach or install any
accessories near the sensor, including
transparent material or aftermarket
grilles. Doing so could cause an ACC
system failure or malfunction. When
the condition that deactivated the
system is no longer present, the
system will return to the “Adaptive
Cruise Control Off” state and will
resume function by simply
reactivating it. NOTE:
If the radar sensor wipe warning
message occurs frequently (e.g. more
than once on every trip) without any
snow, rain, mud, or other obstruction,
have the radar sensor realigned at an
Authorized Maserati Dealer .
Clean Front Windshield Warning
This warning will display and a signal
will indicate when conditions
temporarily limit system performance
due to failed signal reception. This
most often occurs at times of poor
visibility, such as in snow or heavy rain
and fog. The ACC and FCW systems
may also become temporarily blinded
due to obstructions, such as mud, dirt,
or ice on the windshield and fog on
the inside of glass or when driving in
bad weather. In these cases, the
system will have degraded
performance.
The ACC and FCW systems will recover
operation after the vehicle has left
these areas. Under rare conditions,
when the camera is not tracking any
vehicles or objects in its path this
warning may temporarily occur.
If weather conditions are not a factor,
the driver should examine the
windshield and the camera. They mayDriving
5
265

require cleaning or removal of an
obstruction.
When the condition that created
limited functionality is no longer
present, the ACC and FCW systems will
return to full functionality.
NOTE:
If the windshield wiper warning
message occurs frequently (e.g. more
than once on every trip) without any
snow, rain, mud, or other obstruction,
have the windshield and forward-
facing camera inspected at an
Authorized Maserati Dealer .
Service ACC/FCW Warning
If the ACC and FCW systems turn off,
and the system displays a service
warning, there may be an internal
system fault or a temporary
malfunction that limits functionality.
Although the vehicle is still driveable
under normal conditions, ACC and
FCW will be temporarily unavailable. If
this occurs, try activating ACC and FCW
again later, following a key cycle. If the
problem persists, contact an
Authorized Maserati Dealer .Precautions while Driving with
ACC Offset Driving
ACC may not detect a vehicle in the
same lane that is offset from your
direct line of travel, or a vehicle
merging in from a side lane. There
may not be sufficient distance to the
vehicle ahead. The offset vehicle may
move in and out of the line of travel,
which can cause your vehicle to brake
or accelerate unexpectedly. Turns and Bends
When driving on a curve with ACC
engaged, the system may decrease the
vehicle speed and acceleration for
stability reasons, with no target vehicle
detected. Once the vehicle is out of
the curve the system will resume your
original Set Speed. This is a part of
normal ACC system functionality.
Moreover, the radar sensor might
detect a vehicle on a nearby lane or no
longer detect the target vehicle.Driving

Forward Collision Warning
– FCW The Forward Collision Warning (FCW)
system with braking action uses the
same parts already described for
Adaptive Cruise Control (ACC) for
sensing vehicle ahead (hereinafter
“target vehicle”) as well as part of the
warnings/messages on system
condition and activation status.
Full performance can be reached only
when both the sensing parts have
detected a vehicle or, if the car is
equipped with Pedestrian Emergency
Braking (PEB) system, also a
pedestrian. The difference between full and
reduced performance is not visible for
the driver.
Pedestrian Emergency Braking
(PEB) System (if equipped) The Pedestrian Emergency Braking
(PEB) is a sub-system of FCW and it
provides the driver with audible
warnings, visual warnings on the
instrument cluster display, and may
apply automatic braking when it
detect a potential frontal collision with
a pedestrian.
WARNING!
Pedestrian Emergency Braking (PEB) is
not intended to avoid a collision on its
own, nor can PEB detect every type of
potential collision with pedestrian.
The driver has the responsibility to avoid a collision by controlling the
vehicle via braking and steering.
Failure to follow this warning could
lead to serious injury or death.
FCW Operation The FCW provides audible and visual
warnings when a potential collision is
detected. Brake jerk and limited
braking may also be applied
depending on the specific scenario.
FCW monitors the information from
the forward looking radar sensor as
well as the Electronic Brake Controller
(EBC), to calculate the probability of a
forward collision. When the system
determines that a forward collision is
probable, the driver will be provided
with audible and visual warnings and
may provide a warning brake
actuation. If the driver does not take
actuation based upon these
progressive warnings, then the system
will provide a limited level of active
braking to help slow down the vehicle
and mitigate the potential forward
collision. If the driver reacts to the
warnings by braking and the system
determines that the driver intends to
avoid the collision by braking but has
not applied sufficient brake force, theDriving
5
268

system will compensate and provide
additional brake force as required.
When the system determines a
collision with the vehicle in front of
you is no longer probable, the
warning messages will be deactivated.
NOTE:
• Bad weather conditions, like heavy
rain, snow, etc., can lead to reduced
system performance. Under these
conditions relevant objects will not
be detected or detected late by the
system.
• FCW is designed to react in specific
situations in typical traffic scenarios
with objects in the same lane driving
in the same direction, but under
certain conditions it can also react
on stationary objects in the same
lane. It is not designed to react to
oncoming traffic or crossing traffic.
• The FCW alerts may be triggered to
objects other than vehicles such as
guard rails or sign posts based on
the course prediction. This is
expected and is a part of normal
FCW activation and functionality.
• It is unsafe to test the FCW system.
To prevent such misuse of the
system, after four Active Braking
events within a key cycle, the Active
Braking portion of FCW will be deactivated until the next key cycle.
The limit of four events applies to
the brake actuation too.
• FCW will automatically deactivated
when
(ESC OFF) button is pressed
(LED light up).
WARNING!
• Forward Collision Warning (FCW) is
not intended to avoid a collision on
its own, nor can FCW detect every
type of potential collision. The
driver has the responsibility to avoid
a collision by controlling the vehicle
via braking and steering. Failure to
follow this warning could lead to
serious injury or death. The driver is
always in charge to safely drive and
to avoid critical situations, and not
rely on the support of the FCW
system. Driver has to keep in mind
that the system and therefore its
intervention is always subject to the
prevailing physical limits.
• Forward Collision Warning (FCW) is
not intended either to warn or to
apply any brake aid/brake
intervention in case of collisions
with pedestrians (if not equipped with PEB sub-system), bicycles and
not licensable vehicles in general.
Speed Range of Use Speed mph (km/h)
Minimum 0 (0)
Engaged/activated 1.12 (1.8)
Maximum 155 (250)
When the speed is outside the
specified limits, the system
automatically disables without turning
on the corresponding warning light
on the instrument cluster.
FCW Status The driver can adjust FCW sensitivity
or enable/disable the brake actuation
with the other emergency brakings by
touching "Controls" soft-key on MTC+
display. The current setting is indicated
beside to the "Forward Collision
Warning" soft-key. If you want to
change the setting, touch the soft-key
on the side to enter FCW page.Driving
