brake MASERATI GHIBLI 2019 Service Manual

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

whenever the brake pads and/or brake
discs are replaced.
Brake Overheating Driving on mountain roads with steep
slopes or a sports use of the vehicle
could overheat the brake system
components. In these conditions, the
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. The
automatic or manual activation of the
parking brake will ensure vehicle
braking.
Brake overheating could also cause
“squeals” and “vibration”. Use of the Engine Breaking-In Today's most modern production
methods are designed to provide
extremely precise construction and
assembly of components. However,
moving parts do undergo a settling
process, basically in the first hours of
vehicle operation.
Do not drive keeping at a constant
high speed rate for a prolonged time.
While cruising, brief full-throttle
acceleration within the limits of local
traffic laws contributes to a good
break-in. Wide-open throttle
acceleration in low gear can be
detrimental and should be avoided.
The engine oil installed in the engine
at the factory is a high-quality energy
conserving type lubricant. Oil changes
should be consistent with anticipated
climate conditions under which vehicle
operations will occur. For the
recommended viscosity and quality
grades, see “Refillings” in section
“Features and Specifications”.
A new engine may consume some oil
during its first few thousand
miles/kilometers of operation. This
should be considered as a normal part of the break-in and not interpreted as
an indication of malfunction.
Specific Requirements
Avoid exceeding 5000 rpm for the first
620 mi trip (1000 km).
After starting the vehicle, do not
exceed 4000 rpm until the engine has
warmed up sufficiently (coolant
temperature: 149-158°F /65 70°).
While Driving Never travel with the tachometer
indicator approaching the peak rpm,
not even downhill. When the
tachometer indicator is approaching
the peak rpm (red colored zone), take
precautions to avoid exceeding that
limit.
Ensure proper operation of different
devices checking their respective
control telltales.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.
Press ACC button to disable
the CC system.Standard Configuration Optional ConfigurationDriving

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)

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

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

NOTE:
Any change made to tire dimensions
affects performance of Adaptive Cruise
Control and Front Collision Warning
(FCW), if equipped.
The ACC is not activated in the
following conditions:
• When braking.
• When parking brake is activated.
• When automatic transmission is in P
(Park), R (Reverse) or N (Neutral).
• When vehicle speed is out of preset
speed range
• When brakes are overheated.
• When driver door is open.
• When the driver’s seat belt is
unbuckled.
• When the road is particularly steep
(both uphill and downhill) at low
speed.
• When drive mode
(ESC OFF) is
selected.
• When the door is opened at low
speed.
• When there has been an ESC event in
the last 5 seconds, or is still active.
• When there is an object too close in
front of the vehicle.
It is possible that more than one
system is active at the same time such as ACC and ABSA just to mention
some.
While activation of ACC and CC at the
same time is impossible.

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.

(Continued)
• 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
252

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
