2019 MASERATI QUATTROPORTE warning

All-Wheel Drive (AWD
version only) The active on-demand All-Wheel Drive
(AWD) system provides available
optimum traction for a wide variety of
road surface and driving conditions.
The system minimizes wheel slip by
automatically redirecting torque to
the front and rear wheels as necessary.
To maximise fuel economy, the AWD
system automatically disangages
torque distribution on front axle when
road and environmental conditions
are such that wheel slip is unlikely to
occur. When specific road and
environmental conditions require
increased levels of road traction, the
AWD system automatically distributes
the torque between front and rear
axle in order to grant the best driving
experience. Torque distribution is
displayed on the TFT in the “Drive
Mode” main menu. Refer to
paragraph “TFT Display: Menus and
Settings” in chapter “Instrument
Cluster” of section “Dashboard
Instruments and Controls” for further
information. WARNING!
There may be a slight delay for AWD
engagement after a wheel slip
condition occurs.
NOTE:
If the A
WD system service warning
light and message appears after
engine start up, or during driving, it
means that the AWD system is not
functioning properly or is in recovery
mode due to overheating caused by
the excessive wheel spin. In this
condition the vehicle can continue
driving but only rear wheel drive is
working. If the warning light and
message is often activated, it is
recommended to have the vehicle
serviced at an Authorized Maserati
Dealer . Driving

Active Alternator To improve overall efficiency by
reducing the auxiliary loads on the
engine, the vehicle is equipped with a
smart alternator that is mainly active
in the latter energy balance phases
(for example, during braking, coasting
and overloading).
The alternator becomes active when
the battery charge is insufficient and
when the vehicle exits from the
braking and overload situations.
Active Alternator Feature (if feature is
available)
In the I.C.E. screen, the user can
display in the form of dynamic bars
some informative parameters on the
state of battery charge ("CHARGE"),
efficiency of drive style ("EFFICIENCY")
and the matured economy (
bonus
range) expressed in miles (mi) or
kilometres (km). The bonus range (about 37 mi/60 km
for each full of fuel) is automatically
reset every time the vehicle is
refueled.
Parking Brake The vehicle is equipped with an
electric automatic parking brake, also
called EPB (Electric Parking Brake).
The EPB braking action is ensured by a
“Performance Dual Cast” or “Dual
Cast” braking system with dedicated
calliper which acts on each rear brake
disc.
It can be automatically engaged when
the engine is turned off and
disengaged with engine running,
driver seatbelt latched and driver door
closed, while pressing the brake pedal
and operating the shift lever.
Furthermore, EPB can be automatically
engaged above a slope threshold with
the gearshift in P (Park) to avoid
damage to the vehicle. EPB can be
disengaged before turning off the
vehicle.
When the parking brake is applied,
the warning light
lights up on
the tachometer display and the
related message is displayed on the
instrument cluster for 5 seconds (see
“Instrument Cluster” in section
“Dashboard Instruments and
Controls”).Driving
5
243

During engagement and
disengagement procedures, the
warning light
flashes until the
parking brake has reached its
maximum activation force and is
respectively fully released.
In the above-mentioned conditions,
the automatic engagement function
can be deactivated/activated by
selecting the menu item “Vehicle
settings” on the main menu (refer to
paragraph “Deactivating Automatic
Operation” in this chapter).
Manual Engagement/
Disengagement The parking brake can also be
manually engaged or disengaged
when the engine is running or the
ignition switch is in the RUN position,
by pressing the brake pedal and raising the lever located behind the
shift lever.
When the parking brake is applied, the
warning light
lights up on the
tachometer and the related message
will be displayed for 5 seconds on the
instrument cluster.
If you attempt to engage/disengage
the parking brake without having
pressed the brake pedal, a message
will be displayed, warning you to
proceed.
If the engine was turned off when the
automatic engagement device was
deactivated (see “Deactivating
Automatic Operation” in this chapter)
it is possible to shift the parking brake
simply by pulling the lever upward
within 3 minutes after turning off. CAUTION!
The main function of the EPB is to
allow safe parking of the vehicle,
therefore it must only be applied
when the vehicle is already stationary.
If the EPB is used while the vehicle is
moving and decelerating until a speed
lower of 3 mph (5 km/h) and, in
particular, until complete stop
(typically in a sudden brake), it is
necessary to have the EPB system
checked by an Authorized Maserati
Dealer .
WARNING!
• Always hold the brake pedal pressed
during engagement or
disengagement of the parking brake.
• The EPB command activation while
running generates a deceleration of
the vehicle with strong deceleration
(Dynamic Braking). It is therefore
recommended to use this feature
only in case of emergency. The
stability of the car is guaranteed by
the action of the activated ESC
system.Driving

(Continued)
• In case of repetitive requests to reset
the EPB through the messages shown
on the TFT display, please contact an
Authorized Maserati Dealer .
Failure Indication In the event of electric parking brake
system failure, the warning light
on the display will light up and the
related message will show for 5
seconds.
WARNING!
In the event of an EPB failure, take
your vehicle to the nearest Authorized
Maserati Dealer as soon as possible.
Initialize the EPB System after
Re-connecting
the vehicle battery After the detachment and the
subsequent connection of the battery,
on the instrument cluster display the
warning light
light up.
To initialize the EPB system lift, release
and lift again the lever located behind
the shift lever.
Emergency Disengagement
In case of brake lock with complete
electrical system failure, it is necessary
to force the electric actuator on the
rear calipers (see “Emergency Release
of the Parking Brake” chapter in
section “In an Emergency”).
EPB Operation with
Overheated Brakes Driving on mountain roads with steep
slopes or a sports use of the vehicle
could overheat the brake system
components. In these conditions,
parking brake must not be used since
the push of the power actuator might
not be sufficient to ensure vehicle
braking, especially on a slope.
Drive normally without braking to
allow the brakes to cool down a few
minutes before stopping. In this way,
the automatic or manual activation of
the parking brake will ensure vehicle
braking.Parking Before leaving the vehicle, make sure
that the parking brake is fully applied
and place the shift lever in the P (Park)
position.
WARNING!
• Always check that the vehicle is
locked before leaving it.
• Never leave children unattended in
the vehicle.
• Do not park the vehicle on paper,
grass, dry leaves or other flammable
materials.
• Do not leave the engine running
while the vehicle is unattended.
CAUTION!
When you need to park the vehicle on
a steep slope, both with the engine on
and off, it is recommended not only to
engage the parking brake, but also to
shift the shift lever to P (Park) before
leaving the vehicle.
When parking on hill roads, it is
important
to turn
the front wheels
toward the curb on a downhill gradeDriving
5
246

and away from the curb on an uphill
grade.
Apply the parking brake before
placing the shift lever in P (Park),
otherwise the load on the
transmission locking mechanism may
make it difficult to move the shift
lever out of P (Park).
In certain conditions, it is however
advisable to disengage the parking brake manually and slightly apply the
service brake for starting off. This is
advisable when there are obstacles
very close to the vehicle in the
direction in which you intend to move.
“Drive Away Inhibit” strategy In order to avoid a dangerous
condition resulting from leaving the
vehicle “not braked” with running engine and without driver on board,
“Drive Away Inhibit” strategy alerts
the driver with messages on the
instrument cluster display and
sounding chimes, then puts the
transmission in P (Park).
The table shows the vehicle condition
and the action that the system runs to
exit the dangerous condition.
Vehicle condition Action of the driver
The system puts the
transmission in P
(Park) position.• Engine running and speed lower than
1.8 mph (3 km/h).
• Transmission in any position other P
(Park).
• Driver safety belt unlocked.
• Driver door opened.
• Brake pedal pressed. The driver releases the brake pedal to
get out of the vehicle.
Warnings Warnings
• Slow continuous chime.
• The condition of the vehicle not in P
(Park) position will be signaled by a
message on the display. • Fast chime.
• A message which invites to engage
the parking brake to prevent vehicle
movement will be displayed on the
display. Driving

Brake and Stability Control
System The vehicle is equipped with an
Electronic Stability Control System
(ESC), which helps to maintain
directional control in the event of loss
of grip of the tires. The system is able
to detect potentially dangerous
situations for the stability of the
vehicle and automatically sets the
brakes on all four wheels in a
differentiated manner, in order to
provide a torque settlement of the
vehicle.
ESC includes the following subsystems:
• ABS (Anti-lock Braking System);
• EBD (Electronic Brake-force
Distribution);
• TCS (Traction Control System);
• BAS (Brake Assist System);
• BTO (Brake Throttle Override);
• HSA (Hill Start Assist).
WARNING!
• These systems cannot prevent the
natural laws of physics from
affecting the vehicle, nor can they
increase traction, braking or steering
efficiency beyond that afforded by the condition of the vehicle brakes
and tires.
• These systems cannot prevent
collisions, including those resulting
from excessive speed in turns,
following another vehicle too
closely, or hydroplaning.
• The capabilities of a vehicle
equipped with these systems must
never be exploited in a reckless or
dangerous manner that could
jeopardize the driver’s and the
passenger’s safety or the safety of
others.
Electronic Stability Control
(ESC) This system enhances directional
control and stability of the vehicle
under various driving conditions. The
ESC corrects over steering and under
steering of the vehicle by applying the
brake to the appropriate wheel.
Engine power may also be reduced to
assist in counteracting the conditions
of instability and maintain the right
direction. The system is also able to
reduce the engine power.
Through sensors fitted on the vehicle,
the ESC system detects the driver’s
chosen direction comparing it to the
one maintained while running. In case of discrepancy between the required
trajectory and the current one, the ESC
system brakes the appropriate wheel
to counteract over or under steering.
• Oversteer - when the vehicle is
turning more than appropriate for
the steering wheel position.
• Understeer - when the vehicle is
turning less than appropriate for the
steering wheel position.
The ESC system has two available
operating modes:
ESC on
This is the normal ESC operating mode.
At each start-up of the vehicle, the ESC
system is set in this mode and should
be used for most driving conditions.
The ESC should only be turned off for
specific reasons as pointed out in the
following paragraphs.
ESC off
The “ESC off” mode is aimed for a
more spirited driving experience but
also purposeful for driving in deep
snow, sand, or gravel. The current
mode disables the TCS portion of the
ESC and raises the threshold for ESC
activation, allowing higher wheel spin
than normally granted by the ESC
system. The
(ESC OFF) button is
fitted beside the gear shift lever: toDriving
5
248

deactivate the system see “Drive
Mode” in this section.
WARNING!
In SPORT mode the ESC control
thresholds are higher for maximum
performance on dry road surface. To
ensure maximum security of the ESC,
it is recommended not to activate
SPORT mode on surfaces with
medium- and low-grip (e.g., wet,
snow, dirt, etc..) with ESC system
active (
(ESC OFF) button not
pressed).
NOTE:
• When in “ESC off” mode, the TCS
functionality of ESC is deactivated
(except for the limited slip feature
described in the TCS paragraph of
this chapter). All other stability
features of ESC function regularly.
• To improve the vehicle's traction
when driving with snow chains, or
when starting off in deep snow,
sand, or gravel, it may be desirable
to switch to the “ESC off” mode by
pressing the
(ESC OFF) button and
remain in this operational mode no
longer than needed. Once the
situation requiring “ESC off” mode is overcome, turn the ESC on again by
pressing the
(ESC OFF) button.
This may also be performed while in
motion.
Anti-Lock Braking System (ABS)
and Electronic Brake-force
Distribution (EBD) The Anti-Lock Braking System (ABS)
provides increased vehicle stability and
brake performance under most
braking conditions. The system
automatically “pumps” the brakes
during severe braking to prevent
wheel lock-up.
The Electronic Brake-force Distribution
(EBD) prevents the rear wheels from
over-braking and provides greater
control of available braking forces
applied to the rear axle.
WARNING!
The ABS helps prevent the wheels
from locking, but it does not increase
the physical grip limits between the
tires and the road. Therefore, always
keep a safe distance from the vehicle
in front of yours and reduce your
speed when entering a curve. NOTE:
• When
the vehicle's speed is higher
than 7 mph (11 km/h), you may hear
a slight clicking sound as well as
other motor noises. The system is
performing a self-check cycle to
ensure that the ABS is working
properly.
• This self-check occurs each time the
vehicle is started and accelerated
past 7 mph (11 km/h).
ABS is activated during braking under
certain road or stopping conditions.
ABS-inducing conditions can include
ice, snow, gravel, bumps, railroad
tracks, loose debris.
You may also experience the following
when the brake system goes into Anti-
Lock:
• The ABS motor running (it may
continue to run for a short time
after the vehicle stops).
• The clicking sound of solenoid
valves.
• Brake pedal pulsations.
• A slight drop or fall away of the
brake pedal at the end of the stop.
These are all normal characteristics
of ABS functioning.Driving
5
249

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
