together with the standard braking
system.
ESC System Operations
In order to prevent unstable driving
conditions, the ESC system may request
the transmission system to deactivate
gearshifting. The system handles this
request depending on the gear
engaged and on the rpm, and decides
whether to accept it or not.
Driving with Cruise Control
With the Cruise Control function
activated, the transmission system
selects such settings as to provide
enhanced comfort and fuel-economy.
MC Start Strategy
(for MC version only)
With the aim of optimizing standing
starts for performance driving (only
recommended for use in areas closed
to traffic and in accordance with the
Highway Code), the automatic
transmission system is equipped with
quick start strategy.
This strategy is activated when the
following conditions occur
simultaneously:
• AUTO and SPORT modes active;
•
ESC mode off;
• brake pedal depressed. In these conditions, the driver has the
possibility to accelerate and, keeping
the brake pedal depressed, keep the
vehicle standing until reaching an
engine speed between 2300 an 2500
rpm. Then, upon releasing the brake
pedal, have the best standing start
performance.
WARNING!
This strategy must only be used on
vehicles in areas closed to traffic, in
accordance with the Highway Code
and only by skilled drivers.
Transmission Malfunction and
Overheating Conditions
Transmission Failure
Transmission function is electronically
monitored to detect abnormal
conditions. If a condition that could
result in transmission damage is
detected, Transmission Limp Home
Mode will be activated. In this
situation, the transmission may
operate only in certain gears, or may
not shift at all.
CAUTION!
In these conditions, we recommended that you stop the vehicle and turn off
the engine for at least one minute.
When restarting the engine, the
self-diagnosis system may cancel the
malfunction, which will in any case be
recorded by the ECU.
A message and the
warning light
in the instrument cluster will inform
the driver about the transmission
failure.
In failure conditions, the transmission
shift lever can however be shifted to R
(Reverse), N (Neutral) and D (Drive)
position.
When shifting to D (Drive) position,
only a few gears will be available,
depending on the malfunction found.
CAUTION!
If a transmission failure is signaled,
take your vehicle to the nearest
Authorized Maserati Dealer as soon as
possible to have the problem
corrected.
If the failure is signaled when the
engine
is started, it means that the
transmission ECU detected a fault
when the vehicle was last used. Also in
this case, take your vehicle to the
nearest Center of the Authorized
Driving
5
166

Maserati Dealerto have the
transmission checked.
WARNING!
When the transmission is
malfunctioning, drive very carefully
considering that vehicle performance
is reduced. In addition, the reverse
gear safety lock may not be active:
absolutely do not shift the lever to R
(Reverse) when the vehicle is moving.
Transmission Oil Overtemperature
If
the transmission oil temperature
exceeds the operating limit, a message
and the
red warning light
illuminates on the instrument cluster.
In this case, slow down until
temperature returns to normal level
(the light will turn off).
If this is not sufficient, we recommend
to stop the vehicle, shift the lever to
position P (Park) or N (Neutral) and
keep the engine idle until the
red
temperature warning light turns off
and the message disappears from the
display. Resume driving without
demanding high engine performance.
If the
red warning light and the
related message turns on again, it is
advisable to stop the vehicle, turn off
the engine and wait for the engine/transmission assembly to fully
cool down.
Transmission Manual Release of P
(Park) Position
See chapter “Transmission Manual
Release of P (Park) Position” in section
“In an Emergency”.
Onboard Computer (Trip)
The trip computer screen pages are
accessible through the “Trip” softkey
in the lower bar of the MTC+ main
menus.
The selectable submenus are the
following:
• Current Trip.
• Trip A.
• Trip B.
• Service.

can be activated at any time and the
system limits the engine speed rate to
3000 rpm in all gears except for the
6th, unrequested gearshifts could take
place.
In any case, it is advisable to
deactivate
SPORT mode before
selecting ICE (low-grip) mode.
When sequential manual gearshifting
is active, regardless of the mode set
(NORMAL / SPORT / ICE), the
transmission will automatically upshift
or downshift when reaching the
minimum and maximum rpm. This is
to prevent engine overrevving or
underrevving.
(ESC Off) Mode
The ESC system is designed to
automatically activate every time the
engine is started and can be
deactivated by pressing
(ESC Off)
button on the central console for
about 2 seconds. The
(ESC Off)
amber warning light illuminates on
the instrument cluster as well as on
the display, where it is accompanied
by a specific message.
The ESC (Electronic Stability Control)
antiyawing system incorporates all of
the vehicle control systems: ABS, EBD,
ASR and MSR (see "Brake and Stability Control System" in this section for
further information).
The system is fitted with a unit that
predicts the vehicle behavior with
extreme accuracy. The system can
detect when the driver is about to lose
control of the vehicle. In this case, it
can activate the brake calipers
individually and engine control, in
order to create a torque sufficient to
resist the vehicle’s yawing moment.
Press
(ESC Off) button again to
reactivate the system.
The
(ESC On) amber warning light
on the instrument cluster flashes
during all the operating phases.
, the system is automatically disabled
and cannot be re-activated. While
driving, this condition is signaled by
the
(ESC On) amber warning light,
that illuminates both on the
instrument cluster as well as on the
multi-function display, where it is
accompanied by the message “ESC
unavailable go to dealer”.
When the engine is started, the system
malfunction is indicated by the
illumination of the
(ESC On) amber
warning light.
CAUTION!
• In the event of a fault, and with the ESC system disabled (
(ESC Off)
button pressed), the vehicle behaves
as if it were not equipped with this
system: however, we recommend
you contact the Authorized Maserati
Dealer as soon as possible to have
the system checked.
• If you have to tow the vehicle with 2 wheels raised, make sure the key in
the ignition switch is in the STOP
(OFF) position. Otherwise, with the
ESC system active (
(ESC Off)
button not pressed), the control unit
will store a malfunction with
consequent illumination of the
(ESC On) amber warning lights on
the instrument cluster and on the
display. Should this occur, contact
the Authorized Maserati Dealer to
have the system repaired.
• In low- and medium-grip conditions (e.g., rain, snow, ice, sand, etc.) it is
advisable not to activate SPORT
mode, even with the ESC system
active (
(ESC Off) button not
pressed).
Driving

When the system refuses to engage a
gear, an acoustic signal will sound for
a few seconds.
Sequential manual operation can only
be selected from the D (Drive) position
whatever the function (SPORT,
NORMAL) active at the time of the
request. The gear selected by the
automatic transmission will remain
engaged when the transmission shift
lever is moved.
Shifting the lever back to D (Drive),
automatic operation will instantly be
resumed, and a gear will be engaged
based on the driving style and mode
selected.
In the event of a failure of the
sequential manual gearshift system,
the transmission ECU will select
automatic operation.
Gearshift Paddles Operation
In sequential manual operating mode
(MANUAL), upshifting and
downshifting can be controlled not
only with the transmission shift lever
but also with the two paddles
positioned behind the steering wheel.
"+": (UP): upper gearshift paddle.
"–": (DOWN): lower gearshift paddle.Also in automatic transmission mode,
when the transmission lever is in
position D (Drive), you can shift to a
different gear by moving one of the
paddles. This action will temporarily
switch the system to sequential
manual operation.
If you then keep to a constant driving
style (low longitudinal and lateral
acceleration), the gearbox
automatically switches back to
automatic operation.
Gear Shift Indicator Light
In order to improve fuel economy, we
recommend that you shift gears when
the system prompts you to do so. This
will help reduce fuel consumption
without significantly affecting vehicle
performance.
The arrow icon beside the displayed
gear will light up to indicate the
moment the gear change is required.This indicator lights up just before
reaching the required speed for gear
change.
When the new gear is engaged, the
indicator turns off. If the shift runs
late or is not performed at all, the
indicator remains lit for a few seconds
then turns off. As soon as new
conditions requiring further gear
change occur, the indicator light will
illuminate again.
NOTE:
The gearshift indicator will only work
when the transmission is set to manual
sequential operation (see paragraph
"Sequential Manual Operation
(MANUAL)" in this chapter).

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 the parking 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 in
STOP
(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 in MAR (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 an Authorized Maserati
Dealer.
WARNING!
• Always hold the brake pedal pressed
during engagement or
disengagement of the parking brake.
Driving
5
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 nearest Authorized Maserati
Dealer is 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 to STOP
(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 Dealer to 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 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
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
