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).

Calibration Selection
The driver can select, in relation to
road surface conditions, vehicle speed,
driving style and comfort, one of the
two calibration levels provided by the
system: normal or sports-style.
•Normal calibration, active when
SPORT drive mode is disabled
("SPORT" button not pressed), favors
comfort and higher driving stability
with low and average grip
conditions.
•Sport-style calibration, active when
SPORT drive mode is enabled
("SPORT" button pressed) , favors
wheel drive and permits a
dynamic-style driving with optimal
road holding.
Whenever the engine is started, the
system automatically activates
NORMAL drive mode, even if SPORT
drive mode was selected before the
engine was last turned off.
The sport-style calibration can be
selected only with the key in the
ignition switch inMAR (ON)position
and it is enabled by pressing button
"SPORT", even while driving.
When SPORT drive mode is activated,
the word “SPORT” on the instrument
cluster display and the LED on the
button illuminate.WARNING!
SPORT drive mode should not be
activated if the road surface is rough
or slippery.
The electronic suspension control
system works in combination with the
ESC system.
When the suspension is set to normal
calibration, stability is increased under
medium and low grip conditions,
while when it is set to sport-style
calibration, the ESC system optimizes a
sportier driving.
WARNING!
In low- and medium-grip conditions
(e.g., rain, snow, ice, sand, etc.) it is
advisable not to use SPORT drive
mode, even with the ESC system
enabled.
Malfunction Indicators
If one or more electric components in
the system prove to be malfunctioning
while driving, the ECU illuminates the
amber warning light accompanied
by the message “Check suspensions”
on the display. In addition, the ECU
calibrates the shock absorbers to apreset value, thus ensuring a safe
vehicle set up.
Should the malfunction involve one
shock absorber only, this will no
longer be controlled by the ECU and
will therefore remain set as it was
when the fault occurred. It is
therefore possible for one of the four
shock absorbers to work with a fixed
calibration, different from that of the
other ones.
In any case, safe and secure vehicle
driving is always ensured at low
speeds.
CAUTION!
In the event of a malfunction in the
suspension control electronic system,
which will be indicated by the
illumination of the amber warning
light on the display while driving,
keep a moderate speed and have the
vehicle checked as soon as possible by
anAuthorized Maserati Dealer.
If a malfunction occurs while driving,
and this is signaled by the illumination
of the
amber warning light on the
display, it is advisable to stop the
vehicle as soon as possible, turn the
key in the ignition switch toSTOP
(OFF)position and then restart the
engine.
