In this case it is possible to release the
brake pedal and the vehicle will
remain in “AutoStop” with engine off.
Pressing the brake pedal and shifting
transmission into D (Drive) or R
(Reverse) will deactivate the
“AutoStop” condition and restart the
engine.
Start&Stop Deactivated Start&Stop function is deactivated
under the following conditions:
• When SPORT drive mode is activated.
• When
(ESC Off) drive mode is
activated.
• If it has been disabled through the
main menu item “Start&Stop”, via
the controls located on the right side
of the steering wheel, or through

released, when one of the following
conditions occurs:
• The SPORT drive mode or (ESC Off)
drive mode is being activated.
• If the Start&Stop function has been
disabled through the main menu
voice “Start & Stop” (see chapter
“Instrument cluster” in section
“Dashboard Instruments and
Controls”) or through the Start&Stop
hard button on the central console
(see chapter “Drive Mode” in this
section) or via MTC+ in the “Control”
page (see “MTC+ ”Control” Screen”
in section “Dashboard Instruments
and Controls”).
• If shift lever is moved to R (Reverse).
• If the steering wheel is moved to
steer the wheels.
• When the temperature conditions
inside the vehicle do not correspond
to the air conditioning setting.
• When changing the temperature
setting on the air conditioning.
• When the defroster function is being
activated.
• When the battery charge is below
safety value.
• When the accelerator pedal is being
pressed (together with the brake
pedal). • If a long time has passed since the
last automatic stop of the engine.
Occupants Safety Function To enhance occupants safety, the
Start&Stop system monitors if the
driver is present and does not allow
automatic restarting of the engine if
one of the following manoeuvres is
being performed while in “AutoStop”
condition:
• The driver unbuckles his/her seat belt
and releases the brake pedal.
• The driver opens the door and
releases the brake pedal.
• The driver unbuckles the seat belt
and opens the door.
• The driver opens the hood.
All the above-mentioned conditions
deactive the Start&Stop function (the
“AutoStart” is deactivated and the
engine remains off) and the
transmission shifts automatically in P
(Park).
The
telltale will flash to indicate
the Start&Stop function disabling. To
restart the engine it is necessary to
press the brake pedal and push the
START/STOP button.
Move the shift lever to D (Drive) to
drive away. WARNING!
• Even when the vehicle is stopped in
the “Stop (AutoStop)” phase, the
driver is responsible for the vehicle
and the occupants and shall take
care of what happens inside and
outside the vehicle.
• Even when the vehicle is stopped
within the “Stop (AutoStop)” phase,
the vehicle driver is responsible for
the vehicle, the vehicle’s occupants
and the vehicle’s surrounding area.
Never leave the vehicle unattended
with the engine running; doing so
poses a risk of danger. It is a good
practice to always ensure to set the
parking brake and place the
transmission gear selector lever into
the P (Park) position, thereby
ensuring the vehicle will not move,
when performing any vehicle checks,
maintenance and/or service
procedures on the vehicle.
Start&Stop Function Disabling Start & Stop enabled is the default
status.
Under certain driving conditions, when
frequent stops and restarts of the
engine may become annoying, it isDriving

Once it is set in the menu bar, the new
menu will be immediately operational.
NOTE:
The yellow LED on the button
indicates the disabled status of
Start&Stop system and vice versa.
If the driving conditions allow it, the
user can re-enable the Start&Stop
function at any time using one of
previous ways.
NOTE:
After user intervention, the Start&Stop
system will automatically update the
status of the function in all contexts
where it can be modified.
Start&Stop System Failure When the indicator light and the
related message illuminate on the TFT
display (see chapter “Instrument
Cluster” in section “Dashboard
Instruments and Controls”) there is a
malfunction in the Start&Stop system
and the engine cannot be switched off
and restarted automatically. To switch
off or restart the engine it is necessary
to push the START/STOP . Have the
vehicle checked at an Authorized
Maserati Dealer .Automatic Transmission The vehicle is equipped with an
electronically controlled 8-speed
automatic transmission, which
automatically changes gear according
to the vehicle's instantaneous usage
parameters (vehicle speed, road
gradient and accelerator pedal
position).
It is possible to change gear manually
thanks to the “M +/-“ (Manual)
position for the shift lever.
The electronic shift lever replaces the
conventional mechanical lever and has
no mechanical connection to the
transmission. The transmission is
operated by electrical actuators on the
hydraulic system and all commands to
the control system are transmitted by
the CAN network. The lever itself
represents a mere user interface. Gear
positions are simulated by solenoids
inside the lever body, which are
computer-controlled and enable or
disable certain positions of the lever.
The solenoids inside the shift lever
prevent the movement of the lever
towards invalid positions.
The electronically-controlled
transmission provides a precise shift
schedule. The transmission electronics
are self-calibrating, therefore the gearshift behaviour could become
perfect as expected after few
hundreds of miles.
CAUTION!
In order to properly use the automatic
transmission, it is essential that you
read through the whole chapter, so
that you can understand right from
the start what the correct and granted
operations are.
Damage to the transmission may occur
if the following precautions are not
observed:
• Shift into P (Park) only after the
vehicle has come to a complete stop:
this is the default position of the
lever. After engaged P (Park) it is
possible set the ignition switch to
OFF .
• Shift into or out of R (Reverse) only
after the vehicle has come to a
complete stop and the engine is at
idle speed.
• Do not shift between P (Park), R
(Reverse), N (Neutral) or D (Drive)
when the engine is above idle speed
• To effect any change from vehicle
stop to R (Reverse), D (Drive), 1 st

gear, it is necessary to keep the
brake pedal fully depressed.
WARNING!
• It is dangerous to move the shift
lever out of P (Park) or N (Neutral) if
the engine speed is higher than
idlespeed. If your foot is not firmly
pressing on the brake pedal, the
vehicle could accelerate quickly
forward or in reverse. You could lose
control of the vehicle and hit
someone or something. Only shift
into gear when the engine is idling
normally and when your foot is
firmly pressing on the brake pedal.
• Unintended movement of a vehicle
could injure those in or near the
vehicle. As with all vehicles, you
should never exit a vehicle while the
engine is running. Before exiting a
vehicle, always apply the electronic
parking brake, shift the transmission
into P (Park), and turn the engine
off.
• Never leave children alone in a
vehicle, or with access to an
unlocked vehicle. Allowing children
to be in a vehicle unattended is
dangerous for a number of reasons. A child or others could be seriously
or fatally injured. Children should be
warned not to touch the parking
brake, brake pedal or the shift lever.
• When leaving the vehicle, always
remove the key fob and lock your
vehicle.
• Do not leave the key fob in or near
the vehicle. A child could operate
power windows, other controls, or
move the vehicle.
This vehicle is equipped with a feature
which
requires the transmission to be
placed in P (Park) before the engine
can be turned off. This prevents the
driver from inadvertently leaving the
vehicle without having placed the
transmission in P (Park). This system
also locks the transmission in P (Park)
whenever the ignition switch is in the
OFF position.
Automatic Transmission Lever Automatic transmission is operated by
a shift lever with unlock button,
located on the central console, which
can have the following operating
positions:
• P (Park): button control;
• R (Reverse);
• N (Neutral); • D (Drive) automatic forward speed;
• M -/+ (Manual): “+” shifting to
higher gear or “–“ shifting to lower
gear in manual mode (see “Drive
Mode” in this section).
Transmission status is visible on the
lever and on the lower part of the
instrument cluster display.
Shift Lever Movements
Shift lever has two main positions with
a single step selection (backward/Driving

• The P (Park) mode can be
automatically enabled by pressing
the “P” button: if the shift lever was
in “M +/-“ position, will go to central
stable position automatically.
• If using the shift lever in M +/-
(Manual) mode, you can activate it
by moving the lever from D (Drive)
to the left and then forward towards
the “–“ symbol or back towards the
“+” symbol and the gear is shifted.
• To exit P (Park) mode, or to pass
from N (Neutral) to D (Drive) or R
(Reverse) position when the car is
stopped or is moving at a low speed,
the brake pedal must also be
pressed.
CAUTION!
• DO NOT accelerate while shifting
from P (Park) or N (Neutral) to
another mode.
• After selecting a transmission mode,
wait a few seconds before
accelerating. This precaution is
particularly important with a cold
engine. Transmission Status on the Instrument
Cluster
Display
By pressing the unlock button on the
lever, the gear change positions field is
displayed: if you release the button
without moving the lever, the field
disappears after 2 seconds. By
operating instead the lever, the new
range will be indicated in the field
and in the lower part of the display. If the vehicle is in D (Drive) status, in
M +/- (Manual) or temporarily in
manual drive mode, the gear position
is indicated beside the lever status
(“D” or “M”), on the lower part of the
display.
Service Shift Lever In the event of a shift lever
malfunction, a message on the
instrument cluster will invite to stop
the car safety and turn off the engine.Driving
5
227

In this way the system moves the
transmission in P (Park) position.
Automatic Transmission Range P (Park)
Use this position to park the vehicle.
The transmission can be shifted from
“P” position only with the brake pedal
and the unlock button pressed: then
move the shift lever. To move the shift
lever from “P” 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 press the “P”
button first, and then apply the
electronic parking brake by pulling the
trigger upwards. The Instrument cluster will display the
related indicator light
and the
message for 5 seconds.
When parking on a hill, apply the
parking brake before pressing the “P”
button.
For enhanced security, turn the front
wheels toward the kerb on a downhill
and away from the kerb on an uphill
grade. WARNING!
• Never use the P (Park) mode as a
substitute for the electric parking
brake. 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.
• The following indicators should be
used to ensure that you have
engaged the shift lever into the “P”
position:
– when shifting into P (Park), push
the “P” button on the shift lever.
– with the brake pedal released,
verify that “P” position is
illuminated on the shift lever and
in the instrument cluster display.Driving

R (Reverse)
This range is used to move the vehicle
backward.
Switching to R (Reverse) starting from
N (Neutral) is only possible if the
vehicle is moving backwards.
We recommend to shift into R
(Reverse) only after the vehicle has
come to a complete stop.
• Vehicle stationary: switching
between R (Reverse) and D (Drive),
passing from N (Neutral), requires
brake pedal pressed and action on
the lever.
• Vehicle moving: the driver can switch
from R (Reverse) to N (Neutral)
acting on the shift lever without
pressing the unlock button and the
brake pedal.
N (Neutral)
• Vehicle stationary and engine
started: switching from N (Neutral)
to P (Park) requires “P” button
pressed only. Switching from N
(Neutral) to R (Reverse) and/or D
(Drive) requires brake pedal and
unlock button pressed and the
action on the shift lever.
• Vehicle moving: switching from N
(Neutral) to R (Reverse) and/or D
(Drive) requires pressing the unlock button and the action on the shift
lever. Switching to R (Reverse)
starting from N (Neutral) is only
possible if the vehicle is moving
backwards, while switching to D
(Drive) starting from N (Neutral) is
only possible if the vehicle is moving
forwards.
Set the parking brake and shift the
transmission into P (Park) if you must
leave the vehicle.
WARNING!
Do not switch to N (Neutral) and/or
never turn off the ignition to coast
downhill. These are unsafe practices
that limit driver’s response to
changing traffic or road conditions. It
is possible to lose control of the
vehicle and have a collision.
CAUTION!
Towing the vehicle, coasting, or
driving for any other reason with the
transmission in N (Neutral) can result
in severe transmission damage. See
“Towing a Disabled Vehicle” in section
“In an Emergency” for further
information. D (Drive)
This
range should
be used for most
city and highway driving. It provides
the smoothest upshifts and downshifts
and the best fuel economy. The
transmission automatically shifts up
and down through all gears. The D
(Drive) mode provides optimum
driving characteristics under all normal
operating conditions of the vehicle.
• Vehicle stationary: to switch from D
(Drive) to R (Reverse) requires brake
pedal and unlock button pressed
and the action on the shift lever: to
reach N (Neutral) starting from D
(Drive) is possible by only acting on
the shift lever.
• To enable special operations while
the car is moving at a low speed,
such as getting out of marsh or
snow, it is possible to run quickly
from D (Drive) to R (Reverse), and
vice versa, by pressing the unlock
button and acting on the shift lever
passing from N (Neutral).
• Vehicle moving: switching to N
(Neutral) from D (Drive) it is not
necessary to press brake pedal.
• From D (Drive) selected mode it is
always possible to switch to M +/-
(Manual) mode, by move the shift
lever to the left (see followingDriving
5
229

paragraph); to return to “D”
position, move the shift lever to the
right. It is possible to shift from D
(Drive) mode to M +/- (Manual) mode
regardless of car speed.
• When in D (Drive) mode, using the
paddles behind the steering wheel (if
equipped), will cause the system to
enter a temporary function and
enable the manual shift mode. This
range is indicated with the symbols
“+/-” above and below “D” letter on
the gear range field of the display.
The system will then switch back to
automatic mode according to time
elapsed in “temporary” mode and
driving conditions.
At extremely cold temperatures (-23°F /
-30°C or below), transmission may be
affected by the low temperature of
the engine and transmission. Normal
operation will resume once the
transmission temperature has risen to
a normal level.
M +/- (Manual)
This mode is obtained by moving the
shift lever to the left in “M +/-“
position.
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 transmission system
to optimise the engine brake action,
remove undesired shifting into higher
and lower gears and improve the
overall performance of the vehicle.
This mode allows you to move the shift
lever step by step forward “–“ or
backward “+” without pressing the
unlock button. The current
transmission gear is displayed on the
instrument cluster beside “M”.
Manual mode can be activated at any
time, with no need to release the
brake pedal.
In M +/- (Manual) mode, the
transmission will shift up or down (+/–)
if manually selected by the driver by
using the shift lever, or shift paddles
on the steering wheel (if foreseen).
The transmission remains in the
engaged gear until the driver shifts into another higher or lower gear,
except in the following cases.
• Lack of accelerator pedal activity will
cause the transmission to revert to
automatic operation. The
transmission will also upshift
automatically once maximum engine
speed is reached.
• If in SPORT mode, the transmission
will remain in the selected gear even
when maximum engine speed is
reached. The transmission will
upshift only if enabled by the driver.
Manual upshift or downshift will be
maintained as long as SPORT mode is
selected, even by full stroke pedal
press.
• If in “M +/-“ or in SPORT mode, the
transmission will automatically
downshift as the vehicle slows to halt
(to prevent engine lugging) and the
current gear will display on the
instrument cluster. Shifting the shift
lever backward “+” or moving the
right shift paddle “+” towards the
steering wheel when stationary, will
cause the vehicle to start in second
gear. If the vehicle speed is too low,
the system will ignore further
upshifts. Avoid using speed control
when the M +/- (Manual) mode is
engaged.Driving
5
230

NOTE:
The gearshift indicator will only work
when the transmission is set in M +/-
(Manual) mode.
Transmission Malfunction and
Overheating Conditions Transmission Emergency Control
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. In some situations, the
transmission system may not
re-engage if the engine is turned off
and restarted.
A message in the instrument cluster
will inform the driver about the more
serious transmission conditions, and
indicate what actions may be
necessary.
Transmission Oil Overtemperature
If the transmission oil temperature
exceeds the operating limit, 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
temperature red 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.
If the instrument cluster message
indicates that the transmission may
not re-engage after engine shutdown,
perform the following procedure
preferably at an Authorized Maserati
Dealer . In the event of a momentary problem,
the transmission can be reset to regain
all forward gears by performing the
following steps.
• Stop the vehicle.
• Shift the transmission into P (Park), if
possible.
• Turn the engine off.
• Wait approximately 30 seconds.
• Restart the engine.
• Shift the transmission into D (Drive)
and then into the desired gear
range. If the problem is no longer
detected, the transmission will return
to normal operation.
NOTE:
Even if the transmission can be reset,
we recommend that you visit an
Authorized Maserati Dealer at your
earliest possible convenience, which
has diagnostic equipment to
determine if the problem could recur.

All-Wheel Drive (AWD
version only) The active on-demand All-Wheel Drive
(AWD) system provides available
optimum traction for a wide variety of
road surface and driving conditions.
The system minimizes wheel slip by
automatically redirecting torque to
the front and rear wheels as necessary.
To maximise fuel economy, the AWD
system automatically disangages
torque distribution on front axle when
road and environmental conditions
are such that wheel slip is unlikely to
occur. When specific road and
environmental conditions require
increased levels of road traction, the
AWD system automatically distributes
the torque between front and rear
axle in order to grant the best driving
experience. Torque distribution is
displayed on the TFT in the “Drive
Mode” main menu. Refer to
paragraph “TFT Display: Menus and
Settings” in chapter “Instrument
Cluster” of section “Dashboard
Instruments and Controls” for further
information. WARNING!
There may be a slight delay for AWD
engagement after a wheel slip
condition occurs.
NOTE:
If the A
WD system service warning
light and message appears after
engine start up, or during driving, it
means that the AWD system is not
functioning properly or is in recovery
mode due to overheating caused by
the excessive wheel spin. In this
condition the vehicle can continue
driving but only rear wheel drive is
working. If the warning light and
message is often activated, it is
recommended to have the vehicle
serviced at an Authorized Maserati
Dealer . Driving
