pedal pressed. To move the shift lever
from P (Park) position to any other
position, the engine must be switched
on. The engine can be regularly
started in P (Park) range. Never
attempt to use P (Park) while the
vehicle is in motion.
When parking on a level surface, you
may place the shift lever in the P
(Park) position first, and then apply
the electronic parking brake by
pulling the trigger upward.
The Instrument cluster will display the
related
light indicator that flashes
until the maximum engagement force
has been reached.
When parking on a hill, apply the
parking brake before placing the shift
lever in P (Park).
For enhanced security, turn the front
wheels toward the kerb on a downhilland away from the kerb on an uphill
grade.
WARNING!
•Never use the P (Park) position as a
substitute for the Electric Parking
Brake (EPB). Always apply the
parking brake fully when parked to
prevent vehicle movement and
possible injury or damage.
•Make sure the transmission is in P
(Park) before leaving the vehicle.
CAUTION!
• DO NOT race the engine when
shifting from P (Park) or N (Neutral)
into another gear range, as this can
damage the drivetrain.
• Shift the lever to P (Park) position
only when the vehicle is stationary.
Therefore, it is advisable to perform
this maneuver with the brake pedal
depressed.
• To prevent accidental engagement,
the transmission shift lever can only
be shifted from P (Park) to any other
position when the unlock button on
the transmission shift lever and the
brake pedal are depressed.• Before getting out of the vehicle,
check that the Electric Parking Brake
(EPB) is engaged. Shift the
transmission shift lever to P (Park)
position even when you need to get
out of the vehicle only for a few
seconds, leaving the engine running.
If you turn off the engine with the
transmission shift lever in a position
different from P (Park), an acoustic
signal will sound for a few seconds
and a message will be displayed
indicating to shift the lever to P (Park)
position.
When the driver’s door is opened with
the transmission shift lever in a
position different from P (Park), an
acoustic signal will sound for a few
seconds and a message warning the
driver that the transmission shift lever
is not in P (Park) position will be
displayed.
R (Reverse)
This range is used to move the vehicle
backward.
We recommend to shift into R
(Reverse) only after the vehicle has
come to a complete stop.

the efficiency of engine braking
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 recommendedthat 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 thewarning 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 Dealeras 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 theAuthorized

• 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.

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).
