2020 MASERATI GRANTURISMO CONVERTIBLE parking brake

(Continued)
• Driving on parabolic curves will
deactivate the system.
PARK OFF Mode
To deactivate manual operation of the
parking brake, with the engine on,
press the "PARK OFF" button on the
central console. The words “PARK
OFF” appear on the instrument cluster
display for 5 seconds, after which they
remain displayed but in smaller size.
To reactivate automatic operation,
press the "PARK OFF" button once
again, the words “PARK ON” appear
on the display for 5 seconds.
CAUTION!
• In certain conditions when the
battery voltage is low, the electric
parking brake system may
temporarily be deactivated for safety
reasons. Therefore, typically upon
starting the engine, when the
battery voltage drops, the message
“PARK OFF” may temporarily be
displayed on the instrument cluster,
indicating that automatic operation
is temporarily disabled.• In the case of performance starting,
check that the electric parking brake
is disengaged.
For further information see "Parking
Brake" in this section.
Sequential Manual Operation
(MANUAL)
In this mode, the transmission interacts
with the driver in order to allow
manual shift and ensure increased
control of the vehicle. The current
mode allows the gear system to
optimize the engine brake action,
remove undesired shifting into higher
and lower gears and improve the
overall performance of the vehicle.
With automatic transmission selected
(D (Drive) position), shift the
transmission shift lever to position “+”
o “–”.
When this mode is selected, the
symbol “+” or “–” illuminates on the
gear display, based on the position of
the transmission shift lever, and the
gear engaged is shown on the
instrument cluster display.
WARNING!
When sequential manual operation is
selected, upshifting or downshifting
must be performed manually.
To engage the gears, shift the
transmission shift lever to one of the
following two positions:
"+" (UP) to engage a higher gear;
"–" (DOWN) to engage a lower gear.
CAUTION!
• However, some conditions will
remain automatically controlled, for
example, when the engine is
overrevving or underrevving, the
system automatically engages a
higher or lower gear.
• If you request a gearshift in
conditions where the engine is
overrevving or underrevving, the
system will not accept the command.
• The ECU is programmed to control
one gearshift at a time, therefore,
fast and repeated actions will not
necessarily result in a gearshift. A
higher or lower gear is engaged only
if the previous procedure requested
has been completed.

Parking Brake
The vehicle is equipped with an
electric automatic parking brake, also
called EPB (Electric Parking Brake).
It can be automatically engaged when
the engine is turned off and it is
disengaged when, with the engine
running, the accelerator pedal is
depressed.
When the parking brake is applied
(with the key in the ignition switch in
STOP (OFF)position), the
indicator lights up on the rev.
counter display and the related
message is displayed on the instrument
cluster for 5 seconds (see “Instrument
Cluster” in section “Dashboard
Instruments and Controls”).
During engagement and
disengagement procedures, the
indicator flashes until theparking brake has reached its
maximum activation force and is
respectively fully released.
The parking brake is automatically
applied when the engine is turned off
and the vehicle is stationary.
It can only be disengaged when the
engine is restarted.
If the key has been removed from the
ignition switch or is turned inSTOP
(OFF)position, it cannot be
disengaged.
Manual Engagement/
Disengagement
The parking brake can also be
manually engaged or disengaged
when the engine is running and when
the vehicle is moving or the key in the
ignition switch is inMAR (ON)
position, by pressing the brake pedal
and raising the lever located next to
the transmission shift lever.
When the parking brake is applied, the
indicator lights up on the rev.
counter and the related message will
be displayed on the instrument cluster.
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.
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 anAuthorized Maserati
Dealer.
WARNING!
•Always hold the brake pedal pressed
during engagement or
disengagement of the parking brake.
Driving

174

If you attempt to disengage the
parking brake without having
depressed the service brake pedal, a
message will be displayed to warn
you to do so.
•The EPB command activation while
running, generates a deceleration of
the vehicle with strong deceleration
(Dynamic Braking). It is therefore
recommended to use of this feature
only in case of emergency. The
stability of the car is guaranteed by
the action of the activated ESC
system.
Deactivating Automatic
Operation
To deactivate automatic operation of
the parking brake, with the engine
on, press the "PARK OFF" button on
the central console.The words “PARK OFF” appear on the
display for 5 seconds, after which they
remain displayed but in smaller size.
To reactivate automatic operation,
press the "PARK OFF" button once
again, the words “PARK ON” appear
on the display for 5 seconds.
CAUTION!
• In certain conditions when the
battery voltage is low, the electric
parking brake system may
temporarily be deactivated for safety
reasons. Therefore, typically upon
starting the engine, when the
battery voltage drops, the message
“PARK OFF” may temporarily be
displayed on the instrument cluster,
indicating that automatic operation
is temporarily disabled.• In the case of performance starting,
check that the parking brake is
disengaged.
Failure Indication
In the event of electric parking brake
system failure, the
warning light
on the display will light up.
Depending on the message displayed,
it signals the following failures of the
EPB system:
• “Parking brake failure: go to dealer”
If the message warning you to go to
the nearestAuthorized Maserati
Dealeris displayed, drive slowly and
remember that the electric parking
brake device is not functioning.
• “EPB is overheated”
If the vehicle has been stationary
(key in the ignition switch toSTOP
(OFF)position) for about 15 minutes
without using the parking brake,
and the warning light illuminates
again after restarting the engine,
slowly drive to the nearest
Authorized Maserati Dealer.
• “EPB failure only manual unlock
allowed: see handbook”
In this case, follow the manual
emergency deactivation procedure
in order to release the parking brake
(see “Emergency Release of the
Driving
5
175

Parking Brake” in section “In an
Emergency”).
• “Parking Brake system revision: go to
dealer”
The EPB system requires
maintenance, therefore contact an
Authorized Maserati Dealerto have
the system corrected.
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 a
Battery Disconnecting
After the detachment and the
subsequent connection of the battery,
on the instrument cluster display the
warning light will light up.
To initialize the EPB system lift, release
and lift again the lever located next to
the transmission shift lever.
Emergency Disengagement
In case of brake lock with complete
electrical system failure, it is necessary
to act on the electric actuator using
the special tool provided in the tool kit
to release the pressure of the parking
brake shoes (see “Emergency Releaseof 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
Straighten the wheels and turn off the
engine.
Before leaving the vehicle, make sure
that the parking brake is fully applied
in automatic or manual mode and
place the transmission lever in the P
(Park) position.
Remove the key from the ignition
switch.
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. They could catch fire if
they come into contact with hot
parts of the exhaust system.
•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
Driving
5
176

engage the parking brake, but also to
shift the transmission 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 grade
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.
Brake and Stability
Control System
The vehicle is equipped with an
Electronic Stability Control (ESC)
anti-yawing system, 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:
• ASR (Anti-Slip Regulation)
• ABS (Anti-lock Braking System)
• EBD (Electronic Brake-force
Distribution)
• HBA (Hydraulic Brake Assistance)
• BOS (Brake Override System)
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
Driving

brake fluid level immediately (see
"Maintenance Procedure" in section
“Maintenance and Care”). If fluid is
below the minimum level, top up
with the recommended fluid and
contact an Authorized Maserati
Dealer immediately to have the
system checked. Brake fluid leaks
affect the operation of the braking
systems.
•The brake system performance in
terms of active safety is not a reason
for the driver to run unnecessary
risks. The driving style shall always
be suited to weather conditions,
range of visibility and traffic.
•The maximum deceleration that can
be obtained always depends on the
tire grip on the road surface. With
snow or ice on the road the grip is
obviously reduced and the braking
distance is very high, even with the
ABS system.
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 kilometers driven on the road.The high-performance 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 km.
During this first period, the slightly
reduced braking ability must be
compensated for by pressing the brake
pedal harder. This applies 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,
parking brake must not be used since
the push on the brake shoes of the
power actuator might not be sufficientto 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.

and it should not be used when the
vehicle is in motion. Use it when your
vehicle is disabled and it is creating a
safety hazard for other motorists.
When you must leave the vehicle to
seek assistance, the hazard warning
flashers will continue to operate even
though the key has been removed
from the ignition switch.
CAUTION!
• When the hazard warning flashers
are activated, the turn signals
control is disabled.• The extended use of the hazard
warning flashers may wear down
your battery.
