the distance (maximum/average/
minimum) and the position
(front/rear/central/side) of the obstacle
detected.
The color represents the distance,
while the field represents the position.
The green color represents the
maximum distance detected, the
yellow color the medium distance and
the red color the minimum one. The
rear sensors are not shown in the
image on the instrument cluster
display if only the front sensors are
active.
WARNING!
For the system to operate correctly the
sensors positioned on the bumper
must be kept clean (remove any mud,
dirt, snow or ice).
Sensor Range
The sensors allow the system to
monitor the front and rear of the
vehicle; they are positioned so as to
monitor the central and lateral zones
at the front and at the rear of the
vehicle.
In the event of an obstacle located in a
central area, this will be detected at
distances of less than 35 in (0,9 m) at
the front and 59 in (1,50 m) at the rear,
depending on the type of obstacle and
its dimensions.
If the obstacle is located in a lateral
position, it will be detected at
distances of less than 31 in (0,8 m).
Failure Indicators
The system ECU checks all the
components every time R (Reverse)
gear is engaged.
In the event that the parking sensors
fail, the relative
warning light and
message illuminate on the instrument
cluster display.
In the event of a failure signal, stop
the vehicle and turn the key in the
ignition switch toSTOP (OFF)position.
Then try cleaning the sensors or
moving the vehicle away from any
possible ultrasound sources (e.g.
pneumatic truck brakes or pneumatichammers) and rotate the key to the
MAR (ON)position. So, if the
operating failure cause has been
eliminated, system full operation will
be recovered. If however, the failure
beep continues, contact anAuthorized
Maserati Dealerto have the system
checked.
Cleaning the Park Assist
Sensors
When cleaning the sensors, take
special care not to scratch or damage
them; therefore, do not use dry, rough
or hard cloths.
The sensors must be washed with clean
water, possibly adding car shampoo.
Should you need to repaint the
bumper or in case of paint touch-ups
in the sensor area, please contact
exclusively theAuthorized Maserati
Dealer. Incorrect paint application
could affect the parking sensors
operation.

Sport Skyhook Suspension
(for versions/markets,
where provided)
The electronic system controlling the
vehicle suspension uses the
sophisticated on board sensors and is
aimed at optimizing vehicle
performance.
The system is capable of constantly
monitoring suspension damping by
means of the actuator fitted on each
shock absorber (Skyhook type). This
way, the shock absorber setting is
suited to the road surface conditions
and vehicle dynamics, thus improving
passenger comfort and road-holding.
By pressing button “SPORT” on the
central console the driver can choose,
even while driving, a normal or
dynamic-type setting for the
suspension, depending on their own
driving style.This way, the system operates with a
shock absorber “softer” setting in
NORMAL drive mode, and a “harder”
setting if SPORT drive mode is selected
(see “Drive Mode” in section
“Driving”).
The strategy used by the system
controlling suspension damping is
aimed at reducing the vertical
oscillations of the vehicle (rolling and
pitching) to a minimum.
The activation of SPORT drive mode
sets the suspension for sports-style
driving and acts on the ASR and
gearbox systems as well, modifying
their setting for dynamic-style driving.
System Components
The system is controlled by an ECU
which manages the solenoid valves on
each shock absorber in response to the
sensor signals, thus adjusting
suspension damping and setting.The sensors which enable the ECU to
calculate the vehicle speed, vertical
and side acceleration, as well as the
instantaneous braking system pressure,
thereby controlling suspension
damping, are the following:
• front left-hand vertical acceleration
sensor;
• front right-hand vertical acceleration
sensor;
• rear vertical acceleration sensor;
• front left-hand wheel acceleration
sensor;
• front right-hand wheel acceleration
sensor;
• lateral acceleration sensor;
• driving speed sensor;
• brake pedal switch.
Self-diagnostics
Whenever the engine is started, the
system performs a self-diagnostic cycle.
If a malfunction is found, the
amber
warning light is displayed
accompanied by the message “Check
suspensions” (see paragraph
"Malfunction Indicators" in this
chapter).

engage the parking brake, but also to
shift the transmission shift lever to P
(Park) before leaving the vehicle.
When parking on hill roads, it is
important to turn the front wheels
toward the curb on a downhill grade
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.
Brake and Stability
Control System
The vehicle is equipped with an
Electronic Stability Control (ESC)
anti-yawing system, 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:
• ASR (Anti-Slip Regulation)
• ABS (Anti-lock Braking System)
• EBD (Electronic Brake-force
Distribution)
• HBA (Hydraulic Brake Assistance)
• BOS (Brake Override System)
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

• in the event of loss of grip on wet
roads (aquaplaning).
The ASR system works in combination
with the electronic suspension control
system: in normal conditions (SPORT
mode off), stability in low and
medium grip conditions has priority,
while with SPORT mode active, the
system favors traction, thereby
optimizing vehicle performance on dry
asphalt.
The ASR system is automatically
activated every time the engine is
started and can be deactivated by
pressing
(ESC Off) button (see
"Drive Mode" in this section).
ASR System Failure
In the event of a fault, the system is
automatically disabled and cannot be
re-activated. While driving, this
condition is signaled by the
amber
warning light on the instrument
cluster display, which illuminates
together with the message “ASR
unavailable go to dealer”. Also the
(ESC On) amber warning light
illuminates inside the tachometer with
the message indicating that the ESC
system is unavailable. In this case drive
with the greatest care and have the
system immediately checked by the
nearestAuthorized Maserati Dealer.MSR Function
The ASR system also controls the
engine braking torque when the
accelerator pedal is released under
low grip conditions (e.g., snow, ice,
etc.): in these conditions, the high
braking torque provided by the
engine may cause instability of the
vehicle.
The system, using the same sensors as
the ABS, detects skidding of one or
both driving wheels when the
accelerator is released and opens the
motor-driven throttle of the engine
fuel system thereby reducing the
braking torque and re-establishing the
maximum grip conditions for the
driving wheels.
WARNING!
The maximum deceleration that can
be obtained with the engine brake
always depends on the tire grip on
the road surface. Snow or ice
obviously reduce grip values.
WARNING!
California Proposition 65

Anti-Lock Braking System (ABS)
and Electronic Brake-force
Distribution (EBD)
The Anti-Lock Brake System (ABS)
provides increased vehicle stability and
brake performance under most
braking conditions. The system
automatically “pumps” the brakes
during severe braking to prevent
wheel lock-up.
The Electronic Brake-force Distribution
(EBD) prevents the rear wheels from
over-braking and provides greater
control of available braking forces
applied to the rear axle.
