Normal Starting of the
Engine
WARNING!
It is dangerous to run the engine in an
enclosed area. The engine consumes
oxygen and discharges carbon
dioxide, carbon monoxide and other
toxic gases in the atmosphere.
WARNING!
California Proposition 65
Operating, servicing and maintaining
a passenger vehicle or off-road vehicle
can expose you to chemicals including
such as, engine exhaust, carbon
monoxide, phthalates and lead, that
which are know to the State of
California to cause cancer and birth
defects or other reproductive harm. To
minimize exposure, avoid breathing
exhaust, do not idle the engine except
as necessary, service your vehicle in a
well-ventilated area and wear gloves
or wash your hands frequently when
servicing your vehicle. For more
information go to:www.P65Warnings.ca.gov/passenger-
vehicle
When you open a door to get into the
car, the instrument cluster turns on.
The TFT displays the complete
odometer, time, outside temperature
and the
open doors indicator.
Before starting the engine, close the
doors, adjust your seat, the inside and
outside mirrors, fasten your seat belt
and instruct all other occupants to
buckle their seat belts.
Make sure that the Electric Parking
Brake (EPB) is applied.
The shift lever must be in P (Park) or N
(Neutral) position before you can start
the engine. Apply the brakes before
shifting into any driving gear (see
“Automatic Transmission” in this
section).
CAUTION!
• Before starting the engine, switch off
the electrical devices with a high
power consumption (air-conditioning
and heating system, heated rear
window, headlights, etc.).
• Do not start the engine if the fuel
level in the tank is low.
Press the brake pedal and turn the key
in the ignition switch toMAR (ON)
position.
Instrument cluster displays the initial
sequence with warning light and
analog instruments test routine.
Turn the key intoAVVposition and
release it when the engine starts. The
key will return toMAR (ON)position
automatically.
Do not hold the key inAVVposition
for a long time.
If the engine fails to start, the starter
will disengage automatically after 10
seconds. If you wish to stop the
cranking of the engine prior to
starting it, turn the key toSTOP (OFF)
position.
If the engine does not start, turn the
key toSTOP (OFF)position and wait
for the gear display to go off. Then
repeat the entire procedure.
NOTE:
Normal starting of either a cold or a
warm engine is obtained without
pumping or pressing the accelerator
pedal.

Engine Start Failure
CAUTION!
• Do not attempt to push or tow your
vehicle to get it started. Vehicles
equipped with an automatic
transmission cannot be started this
way.
• If the vehicle battery is dead, booster
cables may be used to obtain a start
from a booster battery or the
battery in another vehicle. This type
of start can be dangerous if done
improperly. See “Auxiliary Jump
Start Procedure” in section “In an
Emergency” for further information.
Starting by cold engine
Start-off slowly, avoiding sudden
acceleration and rev the engine up at
low medium speeds. High-
performance driving should be
avoided until the engine temperature
reaches 65-70°C (149-158°F).
Engine Turn-Off
• Place the shift lever in P (Park) (see
“Automatic Transmission” in this
section).
• With the engine at idle, turn the key
in the ignition switch toSTOP (OFF)position. A burst on the accelerator
pedal before turning off the engine
has no purpose and increases fuel
consumption.
WARNING!
Never leave a vehicle out of the P
(Park) position, as it could move.
The key can only be removed from the
ignition switch when the transmission
is in P (Park) position and within 30
seconds after turning the key toSTOP
(OFF)position. If you do not remove
the key within 30 seconds, you will
need to turn it back toMAR (ON)and
then toSTOP (OFF)position to have a
further 30 seconds within which to
remove the key from the ignition
switch.
In the event that the key unlocking
system fails or if it is not possible to
shift the transmission to P (Park)
position, to remove the key you must
turn it toSTOP (OFF)position, then
remove the cap shown in picture using
a pen or sufficiently pointed tool.
Then press the button just uncovered
and at the same time extract the key
from the ignition switch. Once the key
has been removed, refit the removed
cap.

Automatic Transmission
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 automatic transmission has six
forward gear ratios and one reverse
gear. The gears can also be engaged
manually once you have shifted the
transmission shift lever to the sector
provided.
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
permitted 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 and should be used every timethe key in the ignition switch is
turned toSTOP (OFF)position.
• 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
stor
2ndgear, 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 idle
speed. Only shift into gear when the
engine is idling normally and when
your foot is firmly pressing on the
brake pedal.
•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.
•When leaving the vehicle, always
remove the key from the ignitionswitch and lock your vehicle.
•Do not leave the key in or near the
vehicle.
The transmission system is equipped
with "Shift-Lock" and "Key-Lock"
safety functions.
Shift-Lock
This safety function allows you to shift
from P (Park) to another position only
if the brake pedal is depressed. This
prevents the vehicle from involuntarily
jumping forward or backward.
Key-Lock
This function allows you to remove the
key from the ignition switch only
when the transmission shift lever is in
P (Park) position and within a
maximum time of 30 seconds. When
this time has elapsed, the key can no
longer be removed.
Automatic Transmission Lever
Automatic transmission is operated by
a lever with unlock button to engage
R (Reverse) and P (Park) located on the
central console.
By using the transmission shift lever it
is possible to select following
positions, indicated on the gear display
at the side of the transmission shift
Driving

lever. The selected position will
illuminate in white light.
• P (Park);
• R (Reverse);
• N (Neutral);
• D (Drive) automatic forward speed (6
ranges);
• –/+ to downshift or upshift in
sequential manual mode (see "Drive
Mode" in this section).
Transmission status (example shown in
picture: D (Drive)) is visible also on the
central part of the instrument cluster
display.Starting the Engine
The engine can only be started when
the transmission shift lever is in P
(Park) or N (Neutral) position.
WARNING!
Always start the engine holding the
brake pedal depressed.
NOTE:
After starting the engine and setting
off, do not depress the accelerator
pedal before and while shifting the
transmission shift lever. This is
particularly important when the
engine is cold.
Driving the Vehicle
After starting the vehicle, with the
engine idling and the brake pedal
depressed ("Shift-Lock" safety), movethe transmission shift lever to D
(Drive) position or in the position for
sequential manual shifting "+" or "–".
Release the brake pedal and gradually
depress the accelerator pedal.
NOTE:
The transmission shift lever can be
moved to P (Park) position only when
the key in the ignition switch is in the
MAR (ON)position and both the
unlock button on the transmission
lever and the brake pedal are pushed
(Shift-lock safety).
For safety reasons, the transmission
shift lever can be moved from D
(Drive) position to R (Reverse) and P
(Park) position only when unlock
button on the transmission shift lever
is pushed. It is also advisable to
depress the brake pedal during this
maneuver.
NOTE:
•Do not run the engine at top RPM
until it has reached stable operating
temperature.
•In the case of performance starting,
check that the Electric Parking Brake
(EPB) is disengaged.
•For more comfortable starting (with
the transmission lever in D (Drive), R

(Reverse) or MANUAL and the
Electric Parking Brake (EPB)
engaged), push the brake pedal,
manually deactivate the EPB system
by pulling up the lever on the central
console, and push the accelerator
pedal.
Hill Holder Strategy
The Hill Holder strategy helps the
driver when starting-off on uphill
slopes. It activates only following a
vehicle stop when the brake pedal is
released, keeping the vehicle
stationary for a moment, so as to allow
the driver to move his foot from the
brake to the accelerator pedal. This
strategy is activated on slopes with a
gradient of more than 15°.Stopping the Vehicle
Regardless of the position of the
transmission lever, you must only
depress the brake pedal to stop the
vehicle.
WARNING!
•When the transmission shift lever is
in D (Drive, R (Reverse) or MANUAL
position, the engine idling and the
vehicle on an even surface, if the
brake pedal is not depressed, the
vehicle can move.
•Gearshifting is always active and
may be performed even when one
or more doors, the trunk or the
liftgate are open. Therefore, in these
conditions, take great care to avoid
moving the transmission shift lever
and so accidentally engage gears.
The key can be removed from the
ignition switch only when the
transmission lever is in P (Park)
position and within 30 seconds from
turning the key toSTOP (OFF)position.
The letter "P" (“Key-Lock" safety) is
displayed on the instrument cluster for
this entire time. For further
information see "Normal Starting of
the Engine" in this section.Selecting AUTO or MANUAL Operating
Mode
The transmission can be used both in
fully automatic mode (position "D")
and in sequential manual mode
(positions "+" or "–").
To select the mode, shift the
transmission shift lever to:
"D": automatic gearshifting (AUTO);
"+" or "–": sequential manual
gearshifting (MANUAL).
The transmission shift lever can always
be shifted from one position to the
other, even when the vehicle is
moving.
The transmission shift lever can
continuously be shifted from D (Drive)
to "+" or "–". If automatic
gearshifting has been set, the word
“AUTO” and the letter “D” will be
shown on the instrument cluster
display, while if sequential manual
mode has been set, the word
“MANUAL” and the gear engaged will
be shown on the same display.
Automatic Transmission Range
P (Park)
Use this position to park the vehicle. A
transmission device will lock the
driving wheels.
The transmission can be shifted from P
(Park) position only with the brake
Driving
5
152

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.
• Vehicle halted: switching between P
(Park), R (Reverse) and D (Drive)
requires pressing the unlock button
Driving
5
153

on the lever and brake pedal: N
(Neutral) is reached only by pressing
the unlock button on the lever.
• Vehicle moving: the driver can switch
from R (Reverse) to N (Neutral), or
vice versa, by pressing the unlock
button on the shift lever.
When the transmission shift lever is in
R (Reverse) position, the system emits
an acoustic signal for a few seconds.
You can also shift the transmission
shift lever to R (Reverse) position when
the vehicle is not completely
stationary, however, this does not
mean that reverse gear is actually
engaged, since there is a limit speed
above which the gear may not be
engaged. When the speed goes below
this limit, reverse gear is engaged.
CAUTION!
To prevent accidental engagement,
the transmission shift lever can only be
moved from R (Reverse) to any other
position when the unlock button is
pressed. It is advisable to also depress
the brake pedal when shifting to this
position.
N (Neutral)
This range should be used when you
need to move the vehicle.• Vehicle halted and engine started:
switching from N (Neutral) to R
(Reverse), P (Park) and/or D (Drive)
requires brake pedal and unlock
button pressed.
• Vehicle moving: switching from N
(Neutral) to R (Reverse) and/or D
(Drive) requires pressing the unlock
button. Switching to R (Reverse)
starting from N (Neutral) is only
possible if the vehicle is moving
backward, while switching to D
(Drive) starting from N (Neutral) is
only possible if the vehicle is moving
forward.
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, ordriving for any other reason with the
transmission in N (Neutral) can result
in 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.
When this automatic forward gear is
set, the letter “D” illuminates on the
gear display and on the instrument
cluster.
The D (Drive) position provides
optimum driving characteristics under
all normal operating conditions of the
vehicle.
• Vehicle stationary: switching from D
(Drive) to R (Reverse) and/or to P
(Park) requires brake pedal and
unlock button pressed: reaching N
(Neutral) starting from D (Drive) is
allowed by only pressing the unlock
button 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
Driving
5
154

(Drive) to R (Reverse), and vice versa,
by pressing the unlock button on the
transmission shift lever.
• Vehicle moving: switching to N
(Neutral) from D (Drive) requires the
unlock button on the shift lever
pressed.
• From D (Drive) selected mode it is
always possible to switch to
MANUAL mode by shifting the
transmission shift lever to "+" or "–"
position.
The gears will be engaged in relation
to the traveling speed, engine RPM,
accelerator position, speed with which
the pedal is depressed as well as the
traveling conditions (uphill, downhill,
curves).
The system has been programmed to
classify all driving styles, in relation to
the above mentioned parameters, and
to associate them with the various
vehicle settings, which go from
extremely comfortable and economic
driving to racing-style driving. The
setting is selected automatically.
At extremely cold temperatures
(-30°C/-23°F or below), transmission
may be affected by the low
temperature of the engine and
transmission. Normal operation will
resume once the transmissiontemperature has risen to a normal
level.
Transmission Strategy in
Particular Driving Situations
Downhill Driving
When the accelerator pedal is
released, the transmission system
detects that the vehicle is moving
downhill and deactivates upshifting.
When the accelerator pedal is
depressed, upshifting is reactivated
but will be delayed by a few seconds.
When the brake pedal is depressed,
the transmission system downshifts to
provide enhanced engine braking
power.
In other words, when driving
downhill, the transmission system
operates so as to avoid upshifting and
shifting gears when the accelerator
pedal is released, and delays gear
engagement by a few seconds when
the accelerator pedal is depressed.
In addition, when the brakes are
applied, it engages the lowest gear in
order to provide enhanced engine
braking power.
This strategy is aimed at making
downhill driving safer.Driving in Curves
The system detects when the vehicle
goes into a curve through the lateral
acceleration and the steering angle.
Detecting this condition, it controls
gearshifting using a specific mode.
This mode is exited when the vehicle
comes out of the curve, at a distance
that varies depending on the vehicle
speed.
Fast-off Strategy
When the accelerator pedal is fully
released, the system deactivates
upshifting.
The next time the pedal is depressed,
upshifting will be reactivated only
after a few seconds.
Upshifting is also deactivated when
the accelerator pedal is partially
released; the system waits the time
necessary to evaluate if the release
action is completed.
Hot-mode Situations
In the event that the engine oil or
coolant temperature is too high or
both, the transmission system reduces
the maximum engine speed to 4000
rpm.
Therefore, upshifting will occur at this
limit.
This strategy does not apply to
downhill driving, so as to always have
Driving
5
155

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
