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.
Transmission Manual Release of P
(Park) Position
See chapter “Transmission Manual
Release of P (Park) Position” in section
“In an Emergency”. All-Wheel Drive The active on-demand All-Wheel Drive
(AWD) system provides available
optimum traction for a wide variety of
road and off-road surface and driving
conditions. The system minimizes
wheel slip by automatically redirecting
torque to the front and rear wheels as
necessary.
To maximize fuel economy, the AWD
system automatically disengages
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 are often activated, it is
recommended to have the vehicle
serviced at an Authorized Maserati

“NORMAL”, “SPORT ”, “
(Suspension)“ or “I.C.E.” After
selecting this height, once the vehicle
speed goes below 15 mph (24 km/h),
the vehicle height will begin to
lower. To exit “Entry/Exit” mode,
move selector to another position or
drive the vehicle over 15 mph (24
km/h). Automatic lowering of the
vehicle into “Entry/Exit” mode can be
enabled through the MTC+ (refer to
“MTC+ Settings” in section
“Dashboard Instruments and
Controls”). If this feature is enabled,
the vehicle will only lower if the
gearshift lever is in P (Park), the
engine is running, doors and liftgate
are closed and the Pneumatic
Suspension System should be either
in “NORMAL” or “Aero”. The Vehicle
will not automatically lower if the
pneumatic suspension system is in
“Off Road 2” or “Off Road 1” mode.
The lowering will be suppressed
when the ignition is switched off and
a door is opened to prevent setting
the alarm off.
Lowering Vehicle Height for Inactivity
Lowering of vehicle ground clearance
after a long period of inactivity should
be considered normal since it is due to a drop of pressure in the pneumatic
suspension system.
Approximately, after one week of
inactivity, vehicle ground clearance will
lower by 0.4 in (10 mm). To set off the
drop of pressure due to inactivity, it is
necessary to start the engine and allow
some time until system reaches
operating pressure and lifts the vehicle
to set ride height. A message on
instrument cluster display will warn
driver when set ride height is reached.
Driving vehicle before the set riding
height is reached is not safe and could
damage suspension components.
WARNING!
After a long period of vehicle
inactivity, drive only when vehicle
reaches set ride height to prevent any
problems of the pneumatic suspension system from limiting occupants'
safety.
"Launch Control" Mode
(TROFEO version only) "Launch Control" mode is a
performance start procedure.
By activating this procedure you get
the best possible acceleration from
standstill of the car.
This mode allows you to ground the
torque necessary to prevent the
wheels from slipping during
acceleration performance.
To make a performance start in
"Launch Control" mode, the following
conditions must be met:
• Water and transmission temperature
in proper range.
• No engine, AWD and on board
systems faults.
• The vehicle must be traveled at least
440 mi (700 km).
• "CORSA" drive mode on.
• Shift lever in "D" or"M +/-" position.
• The vehicle must be stationary on a
level road surface.
• The driver door closed and the safety
belt fastened.Driving

Brake and Stability
Control System The vehicle is equipped with an
Electronic Stability Control System
(ESC), 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:
• ABS (Anti-lock Braking System);
• EBD (Electronic Brake-force
Distribution);
• TCS (Traction Control System);
• BAS (Brake Assist System);
• BTO (Brake Throttle Override);
• HSA (Hill Start Assist);
• ROM (Roll-Over Mitigation);
• TSM (Trailer Sway Mitigation);
• HDC (Hill Descent Control).
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
ESC system brakes the appropriate
wheel to counteract over or under
steering.
• Oversteer - when the vehicle is
turning more than appropriate for
the steering wheel position.
• Understeer - when the vehicle is
turning less than appropriate for the
steering wheel position.
The ESC system has two available
operating modes:
ESC on
This is the normal ESC operating
mode. At each start-up of the vehicle,
the ESC system is set in this mode and
should be used for most driving
conditions. The ESC should only be
turned off for specific reasons as
pointed out in the following
paragraphs.
ESC off
The “ESC off” mode is aimed for a
more spirited driving experience but
also purposeful for driving in sand, or
gravel. The current mode disables the
TCS portion of the ESC and raises theDriving

WARNING!
• The ABS contains sophisticated
electronic equipment that may be
susceptible to interference caused
by improperly installed or high
output radio transmitting
equipment. This interference can
cause possible loss of anti-lock
braking capability. Installation of
such equipment should be
performed by qualified Maserati
personnel.
• Pumping the Anti-Lock Brakes will
diminish their effectiveness.
Pumping brakes makes the stopping
distance longer. Just press firmly on
your brake pedal when you need to
slow down or stop.
• The ABS installed to this vehicle
does not control trailer braking
system. Pay utmost attention when
driving on slippery ground since the
trailer traction might get poorer.
• Do not modify the vehicle braking
system to control the trailer brakes.
The hydraulic system controlling
vehicle braking must remain
independent from trailer braking
system. Traction Control System (TCS) The current device is an integral part
of the ESC system. It operates
automatically by reducing the power
transmitted by the engine in case of
slipping, loss of grip on wet floor
(aquaplaning), acceleration on
slippery snow-covered or frozen
surfaces, etc.
Activating under slip conditions
different control systems:
• if slippage affects both drive wheels,
it reduces the power transmitted by
the engine;
• if slippage only affects one drive
wheel, it brakes the slipping wheel
automatically.
Brake Assist System (BAS) This system completes the ABS system
by optimizing the vehicle braking
capacity during emergency brake
maneuvers. The system detects an
emergency braking situation by
sensing the rate and amount of brake
application and then applies optimum
pressure to the brakes in order to help
reduce braking distances.
The quick brake coupling is optimal
for BAS performances. In order to fully
exploit the system, apply continuous
brake pedal pressure during the entire vehicle stop sequence. Do not reduce
brake pedal pressure earlier than
required. Once the brake pedal is
released, the BAS is deactivated.
Brake Throttle Override (BTO) To complete the range of systems that
assist braking, the vehicle is equipped
with BTO, which is designed to stop
the vehicle even when it is during
acceleration. If the brake pedal is
depressed together with the
accelerator, the system does not
consider as “conflict” the sequence
“brake-first-then-accelerator” of pedal
application and it will not engage the
BTO. When the system recognizes that
the accelerator pedal is stuck pressed
and the sequence “accelerator-first-
then-brake-pressed” (this sequence is
recognized as a “conflict”), the engine
power will be automatically reduced
and, if the driver continues to depress
the accelerator and the brake pedal,
the system can make the vehicle come
to a complete stop.
Additionally, if the brake pedal is
released when the accelerator is still
stuck pressed, the corresponding
engine torque increase gradually to a
safe value.
During this event, the ETC light
indicator will illuminate. The systemDriving
5
275

exits from this strategy when the
accelerator pedal is completely
unstuck.
Hill Start Assist (HSA) The HSA system is designed to assist
the driver when starting a vehicle
uphill. HSA will maintain the level of
brake pressure applied for a short
period of time also after releasing the
brake pedal.
If the driver does not apply the
throttle during this short period of
time, the system will release brake
pressure and the vehicle will start
sloping down. The system will release
brake pressure proportionally to the
amount of throttle/torque applied as
the vehicle starts to move in the
chosen direction.
HSA Activation Criteria
The following criteria must be met in
order for HSA to activate:
• vehicle is stationary;
• gear selection matches vehicle uphill
direction (i.e., vehicle facing uphill is
in forward gear; vehicle backing
uphill is in reverse gear).
HSA will work in R (Reverse) and all
forward gears when the activation
criteria have been met. The system will not activate if the
transmission is placed in N (Neutral) or
P (Park).
Roll-Over Mitigation (ROM) This system anticipates the potential
for wheel lift by monitoring the
driver's steering wheel input and the
speed of the vehicle. When ROM
determines that the rate of change of
the steering wheel angle and vehicle's
speed are sufficient to potentially
cause wheel lift, it then applies the
appropriate brake and may also
reduce engine power to lessen the
chance that wheel lift will occur.
ROM will only intervene during very
severe or evasive driving maneuvers.
ROM can only reduce the chance of
wheel lift occurring during severe or
evasive driving maneuvers. It cannot
prevent wheel lift due to other factors,
such as road and off-road conditions,
leaving the roadway, or striking
objects or other vehicles.
WARNING!
Many factors, such as vehicle loading,
road and off-road conditions, and
driving conditions, influence the
chance that wheel lift or rollover may occur. ROM cannot prevent all wheel
lift or roll-overs, especially those that
involve leaving the roadway or
striking objects or other vehicles. The
capabilities of a ROM-equipped
vehicle must never be exploited in a
reckless or dangerous manner, which
could jeopardize the user’s safety or
the safety of others.
Trailer Sway Mitigation (TSM) TSM uses sensors in the vehicle to
recognize an excessively swaying
trailer and will take the appropriate
actions to attempt to stop the sway.
The system may reduce engine power
and apply the brake of the
appropriate wheel(s) to counteract the
sway of the trailer. TSM will become
active automatically once an
excessively swaying trailer is
recognized.
TSM cannot stop all trailers from
swaying. Always use caution when
towing a trailer and follow the trailer
tongue weight recommendations.
Refer to “Trailer Towing” in this
section for further information. When
TSM is functioning, the “ESC
Activation/Malfunction Indicator
Light” will flash (see “Instrument
Cluster” in section “DashboardDriving

Lane Keeping Assist - LKA
(optional, with ACC only) This system was designed especially
for highway or freeway driving, to
reduce the risk that the vehicle, under
particular circumstances, accidentally
departs from the lane in use. When
this happens, graphic instructions on
instrument cluster display together
with steering torque application and
steering wheel vibration (depending
on the distance to the line) warn the
driver that the vehicle is going out of
the lane and initiate a steering
maneuver to try to prevent the lane
exit.
To detect lane lines, the system uses
the forward-facing camera behind of
the rear-view mirror, which is the same
one used also by the lighting system
to manage the automatic high beams.
The logic core is in the front radar.
LKA system remembers the condition
it was in before turning off the
vehicle.
Refer to “MTC+ "Controls" Screen” in
section “Dashboard Instruments and
Controls” for further information. NOTE:
In case of wet road or raining
conditions the function could be
disabled by the system in order to
minimize the risks.
Speed Range of Use Speed mph (km/h)
Minimum 37 (60)
Engaged/activated 37 (60)
Maximum 112 (180)
Customized Settings LKA is configurable by the driver in
order to maximize its efficiency based
on the driver driving style and the
expectation of the system, reducing at
the same time the possible
invasiveness.
Entering "Controls" page on MTC+
display the driver can see the current
setting beside the "Lane Keeping
Assist" soft-key.
Touching “Lane Keeping Assist”
soft-key can disable or enable the
system. Touching the soft-key on the side the
driver can change the setting.
Driver warnings can be only "Visual"
or "Visual & Haptic" (default mode).
System response can be set to "Early",
"Medium" (default mode) or "Late".
System reaction force can be set to
"Low", "Medium" (default mode) or
"High".
Meanings of Settings
• "Visual" only: the system will not
request any steering torque/Driving
5
301

vibration to correct the car trajectory.
The system will only show on the TFT
display when the vehicle is passing
the lane.
• "Visual & Haptic": the system will
apply steering torque when lane
departure is detected while showing
at the same time the proper cluster
indication, adding to this steering
vibration when the departure is very
imminent.
When "Visual & Haptic" is selected and
LKA is enabled then the following
menu will be used by the system.
• "LKA Sensitivity": it tunes the
distance to the lane boundary where
the system will start to apply steering
torque.
• "LKA Strength": it tunes the steering
torque value to have a stronger or
weaker trajectory correction/
deviation.
WARNING!
In rare cases, Lane Keeping Assist
(LKA) may make an inappropriate
steering torque application. LKA may
be interrupted at any time counter
steering. Lack of attention may lead to
serious injury or death. System Availability The ADAS systems (LKA, CC, ACC, FCW
and HAS) help the driver while driving.
These systems can be set and
monitored simultaneously on the
display, after opening “Driver Assist”
menu (see paragraph “TFT Display:
Menus and Settings” under
“Instrument Cluster” in section
“Dashboard Instruments and
Controls”).
LKA is designed for an attentive driver;
therefore the system is available only
when his/her hands are on the steering
wheel or with hands off only for a very
limited amount of time. When the
system is enabled it will trigger cluster
warning in case at least one hand is
not detected on the steering wheel.
The torque application as well as the
vibration are suppressed/inhibited in
case of: high driver torque in the
steering wheel, high lateral
acceleration, trailer connected to the
proper control module, hands not on
the steering wheel detected for more
than a certain time.
High dynamic driving behaviors,
driving on the lane boundary or
driving off course will prevent the
function from working. FCW braking
and stability system interventions (ESC, ABS) will also prevent the system from
operating. Changing lane results in
system inhibition for a certain time. In
addition, the driver must respect some
road characteristics such as
minimum-maximum width, lanes
clearly defined by two lane boundaries
and for a limited time, the presence of
at least one lane boundary.
NOTE:
• In case of wet road or raining
conditions the function could be
disabled by the system in order to
minimize the risks.
• With lane boundaries it is mainly
referred to painted lines,
nevertheless the system in good
conditions might properly recognize
as valid lane boundaries also other
types (for example road edges, curbs,
etc..).
Being this function used to prevent
unintentional lane change/lane drift, it
will be temporary suppressed/inhibited
by a turn indicator activation,
therefore, graphic warning, steering
torque application and vibration will
be terminated. In this condition in case
of a vehicle detected by the Blind Spot
Assist (BSA) system in the covered area
on the proper side, there can be theDriving
