2019 MASERATI QUATTROPORTE brake light

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

• 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

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
5
250

If the driver does not apply the
throttle during this short period of
time, the system will release brake
pressure and the vehicle will start
sloping down. The system will release
brake pressure proportionally to the
amount of throttle/torque applied as
the vehicle starts to move in the
chosen direction.
HSA Activation Criteria
The following criteria must be met in
order for HSA to activate:
• vehicle is stationary;
• gear selection matches vehicle uphill
direction (i.e., vehicle facing uphill is
in forward gear; vehicle backing
uphill is in reverse gear).
HSA will work in R (Reverse) and all
forward gears when the activation
criteria have been met.
The system will not activate if the
transmission is placed in N (Neutral) or
P (Park). Using the Brakes CAUTION!
To obtain a good performance by
brake pads and discs, avoid sudden
braking during the first 190 mi
(300 km).
The pad wear limit is indicated by the
illumination
of the
warning light
and by a message on the
instrument cluster.
In this event, please contact an
Authorized Maserati Dealer .
WARNING!
Riding the brakes can lead to brake
failure and possibly an accident.
Driving with your foot resting or
riding on the brake pedal can result in abnormally high brake temperatures,
excessive lining wear, and possible
brake damage. In an emergency full
braking capacity may be impaired.
Brake Pads and Brake Discs Wear on the brake pads and brake
discs depends to a great extent on the
driving style and the conditions of use
and therefore cannot be expressed in
actual miles driven on the road.
The brake system is designed for
optimal braking effect at all speeds
and temperatures.
Certain speeds, braking forces and
ambient conditions (e.g. temperature,
humidity and long outdoor stopping
periods) can therefore cause the
brakes to “squeal”. This is normal and
will cease after a few brakings.
New Brake Pads and/or Brake
Discs New brake pads have to be “broken
in”, and therefore only attain optimal
friction to the brake disc when the
vehicle has covered several hundreds
of miles.
During this break-in period, the
slightly reduced braking ability must
be compensated for by pressing the
brake pedal harder. This appliesDriving

WARNING!
Never leave the electronic Cruise
Control system on when not in use.
You could accidentally set the system
or cause it to go faster than you want.
Always leave the system off when you
are not using it.
Speed Range of Use Speed mph (km/h)
Minimum 18 (30)
Engaged/activated 18 (30)
Maximum 130 (210)
Setting Desired Speed Turn on the CC function. When the
vehicle has reached the desired speed
(in the example: 60 mph), push
downward the multifunction switch
(SET -) and release.
The
green light below the desired
speed will illuminate on the
instrument cluster display. Release the accelerator and the vehicle
will operate at the selected speed.
NOTE:
The vehicle should be traveling at a
steady speed and on level ground
before pushing the switch downward.
Pressing the
“ON/OFF” button or
the ACC Gap button for 2 seconds (in
the Optional Configuration) or moving
the ignition switch in OFF position
erases the set speed memory.
Changing Speed Setting Pushing the multifunction switch
upward (RES +) or downward (SET -)
once, or by holding it down, will
enable to increase or decrease the set
speed by one unit (1 mph or 1 km/h). If
the car is equipped with ADAS
Systems, the single press of the
multifunction switch will increase or decrease the set speed of 1 mph or
1 km/h; a continuous pressure of the
same will increase or decrease the set
speed of 5 mph or 10 km/h.
Release the switch when the desired
speed is reached, and the new set
speed will be visualized below the
green light.
Each subsequent tap of the
multifunction switch will increase or
decrease the speed by 1 mph or
1 km/h.
Temporary Deactivation A soft tap on the brake pedal, pressing
the multifunction switch (CANC), or
normal brake pressure while slowing
the vehicle will temporarily deactivate
the CC without erasing the set speed
memory. The
white light with
below the set speed will appear on the
display.Driving

safety system and is not designed to
prevent accidents.
The ACC allows driver to keep Cruise
Control active in limited or moderate
traffic conditions with no need to
constantly restore the Cruise Control.
The ACC uses a radar sensor, located
on the front grille behind the trident,
and the forward-facing camera behind
the internal rear-view mirror to detect
the presence of a vehicle ahead at a
close distance and moving in the same
direction.
This vehicle, in this chapter, will be
indicated as "target vehicle" or
"vehicle ahead".
NOTE:
• If the sensor detects no vehicle
ahead, the ACC system will maintain
set steady speed.
• If the ACC sensor detects a vehicle ahead, the ACC system automatically
kicks in by slightly accelerating or
braking (to avoid exceeding the
initially set speed) so that the vehicle
keeps present distance, trying to
adapt to the speed of the detected
vehicle ahead.
WARNING!
• The Adaptive Cruise Control (ACC) is
designed to increase vehicle driving
comfort. It must not be considered
as a means of replacing the required
attention of the driver. The driver is
always required to drive carefully.
The driver is always required to pay
utmost attention to driving
conditions (road, traffic, weather)
and style (speed, distance from
sensed vehicle ahead, brake use).
Driver has the full responsibility of
the vehicle therefore his attention is
crucial to keeping vehicle control, in
particular when approaching curves
and situations with heavy traffic.
Failure to follow these warnings can
result in a collision and death or
serious personal injury.
• In some driving scenarios, the ACC
could have detection problems. In
such cases, the ACC could kick in late or unexpectedly. The driver must be
careful since his/her intervention
could be necessary.
• It is always the driver’s responsibility
to obey speed limits and to keep
minimum legal distance to the
preceding vehicle.
• ACC system can decelerate only with
limited braking, it cannot execute
emergency braking.
The ACC system:
•
Does not activate/react in the
presence of pedestrians, bicycles,
incoming traffic from the opposite
direction and steady objects such as a
vehicle stuck in a traffic jam.
• Is meant for the use on highways and
well-built roads, not for city traffic or
mountain roads.
• May not have enough time to react
and/or decelerate sufficiently on
vehicles when lane is changed too
quickly or the relative speed is too
high. In such cases the driver has to
react appropriately and without any
acoustic/visual and warning.
• Cannot consider road, traffic and
weather conditions and might prove
limited when visibility is poor.
• Does not always fully recognize
complex driving conditions and thisDriving
