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

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

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.
“Drive Away Inhibit” strategy In order to avoid a dangerous
condition resulting from leaving the
vehicle “not braked” with running engine and without driver on board,
“Drive Away Inhibit” strategy alerts
the driver with messages on the
instrument cluster display and
sounding chimes, then puts the
transmission in P (Park).
The table shows the vehicle condition
and the action that the system runs to
exit the dangerous condition.
Vehicle condition Action of the driver
The system puts the
transmission in P
(Park) position.• Engine running and speed lower than
1.8 mph (3 km/h).

CAUTION!
• Under normal conditions, all red
warning lights on the instrument
cluster display should be off. When
they come on, this indicates a
malfunction. Refer to “Instrument
Cluster” in section “Dashboard
Instruments and Controls”.
• Continuing to drive when a red
warning light is on could cause
serious damage to the vehicle and
affect its performance.
Onboard Diagnostic System Your vehicle is equipped with a
sophisticated onboard diagnostic
system. This system monitors the
performance of the emissions, engine,
and automatic transmission control
systems. When these systems are
operating properly, your vehicle will
provide excellent performance and
fuel economy, as well as engine
emissions well within current local
regulations of various countries.
If any of these systems require service,
the system will turn on the
Malfunction Indicator Light (MIL).
It will also store diagnostic codes and
other information, which your Authorized Maserati Dealer will use to
service your vehicle. Although the
vehicle will still be driveable and not
need towing, contact an Authorized
Maserati Dealer for service as soon as
possible.
CAUTION!
• Prolonged driving with the
Malfunction Indicator Light
(MIL) on could cause further damage
to the emissions control system. It
could also affect fuel economy and
drivability. The vehicle must be
serviced before any emissions tests
can be performed.
•Ifthe
Malfunction Indicator
Light (MIL) is flashing while the
engine is running, severe catalytic
converter damage and power loss will soon occur. Immediate service is
required at an Authorized Maserati
Dealer .
• After the problem has been solved,
the Authorized Maserati Dealer
personnel will perform specific tests
for a complete check of the system
and, if necessary, road tests.Driving

Display Warnings and
Maintenance of ACC and FCW
Systems Wipe Front Radar Sensor Warning
This warning will display and a signal
will indicate when conditions
temporarily limit system performance
due to sensor poor or failed signal
reception. This most often occurs at
times of poor visibility, such as in snow
or heavy rain. The ACC and FCW
systems may also become temporarily
blinded due to obstructions, such as
mud, dirt or ice on the radar sensor. In
these cases, the system will be
disabled.
This message can sometimes be
displayed while driving in highly
reflective areas (i.e. tunnels with
reflective tiles, or ice and snow). The
ACC and FCW systems will recover
operation after the vehicle has left
these areas. Under rare conditions,
when the radar is not tracking any
vehicles or objects in its path this
warning may temporarily occur.
If weather conditions are not a factor,
the driver should examine the sensor.
It may require cleaning or removal of
an obstruction. The sensor is located in
the center of the front grille, behind
the Maserati trident. To keep the ACC System operating
properly, it is important to note the
following maintenance items:
• Always keep the sensor clean.
Carefully wipe the sensor lens with a
soft cloth. Be cautious not to
damage it.
• Do not remove any screws from the
sensor. Doing so could cause an ACC
system malfunction or failure and
require a sensor realignment.
• If the sensor or front end of the
vehicle is damaged due to a collision,
see your authorized dealer for
service.
• Do not attach or install any
accessories near the sensor, including
transparent material or aftermarket
grilles. Doing so could cause an ACC
system failure or malfunction. When
the condition that deactivated the
system is no longer present, the
system will return to the “Adaptive
Cruise Control Off” state and will
resume function by simply
reactivating it. NOTE:
If the radar sensor wipe warning
message occurs frequently (e.g. more
than once on every trip) without any
snow, rain, mud, or other obstruction,
have the radar sensor realigned at an
Authorized Maserati Dealer .
Clean Front Windshield Warning
This warning will display and a signal
will indicate when conditions
temporarily limit system performance
due to failed signal reception. This
most often occurs at times of poor
visibility, such as in snow or heavy rain
and fog. The ACC and FCW systems
may also become temporarily blinded
due to obstructions, such as mud, dirt,
or ice on the windshield and fog on
the inside of glass or when driving in
bad weather. In these cases, the
system will have degraded
performance.
The ACC and FCW systems will recover
operation after the vehicle has left
these areas. Under rare conditions,
when the camera is not tracking any
vehicles or objects in its path this
warning may temporarily occur.
If weather conditions are not a factor,
the driver should examine the
windshield and the camera. They mayDriving
5

require cleaning or removal of an
obstruction.
When the condition that created
limited functionality is no longer
present, the ACC and FCW systems will
return to full functionality.
NOTE:
If the windshield wiper warning
message occurs frequently (e.g. more
than once on every trip) without any
snow, rain, mud, or other obstruction,
have the windshield and forward-
facing camera inspected at an
Authorized Maserati Dealer .
Service ACC/FCW Warning
If the ACC and FCW systems turn off,
and the system displays a service
warning, there may be an internal
system fault or a temporary
malfunction that limits functionality.
Although the vehicle is still driveable
under normal conditions, ACC and
FCW will be temporarily unavailable. If
this occurs, try activating ACC and FCW
again later, following a key cycle. If the
problem persists, contact an
Authorized Maserati Dealer .Precautions while Driving with
ACC Offset Driving
ACC may not detect a vehicle in the
same lane that is offset from your
direct line of travel, or a vehicle
merging in from a side lane. There
may not be sufficient distance to the
vehicle ahead. The offset vehicle may
move in and out of the line of travel,
which can cause your vehicle to brake
or accelerate unexpectedly. Turns and Bends
When driving on a curve with ACC
engaged, the system may decrease the
vehicle speed and acceleration for
stability reasons, with no target vehicle
detected. Once the vehicle is out of
the curve the system will resume your
original Set Speed. This is a part of
normal ACC system functionality.
Moreover, the radar sensor might
detect a vehicle on a nearby lane or no
longer detect the target vehicle.Driving

Using ACC on Hills
When driving on steep hills, ACC may
not detect a vehicle in your lane when
the vehicle reaches the crest.
Depending on the speed, vehicle load,
traffic conditions, and the steepness of
the hills, ACC performance may be
limited.
Lane Changing
ACC may not detect a vehicle until it is
completely in the lane in which you
are traveling.
In the illustration shown, ACC has not
yet detected the vehicle changing lane
and it may not detect the vehicle until
it is too late for the driver to take
action. ACC may not detect a vehicle
until it is completely in the lane. There
may not be sufficient distance to the
lane changing vehicle.
Always be attentive and ready to
apply the brakes if necessary. Narrow Vehicles
Some narrow vehicles (like
motorcycles) traveling near the outer
edges of the lane or edging into the
lane are not detected until they have
moved fully into the lane. There may
not be sufficient distance to the
vehicle ahead. Stationary Objects and Vehicles
ACC does not react to stationary
objects and stationary vehicles. For
example, ACC will not react in
situations where the vehicle you are
following exits your lane and the
vehicle ahead is stopped in your lane.
Always be attentive and ready to
apply the brakes if necessary.

providing limited autonomous braking
or additional brake support if the
driver is not braking adequately in the
event of a potential frontal collision.
In this state the system disables the
brake jerk.
Limited Operation and Service
Warning The messages indicating on display the
limited functionality or service at an
Authorized Maserati Dealer required
are the same as for the ACC system.
For further details, refer to “Adaptive
Cruise Control – ACC” in this section.
NOTE:
• The adjustment of the sensor could
be affected by strong shocks or light
collisions. This could affect the
system by reducing the systems
performance or could increase the
false positive rate. The adjustment of
the radar system has to be proved or
a new adjustment has to be
performed by an Authorized
Maserati Dealer .
• The radar system requires specific
feature to detect objects. The
detection could be disturbed/
reduced by environment influences,
for example by electrical field or the
object itself. Object with small radar reflection properties could not be
detected or detected late.

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 initiates a steering maneuver
to try to prevent the lane exit.
To detect lane lines, the system uses
the forward-facing camera behind 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.
