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.

checking for cuts, frays, and loose
parts. Damaged parts must be
replaced immediately.
• Do not disassemble or modify the
system.
• If the belt has been sharply pulled,
for example as the result of an
accident, the safety belt, together
with the anchoring devices, the
anchoring device mounting screws
and the pretensioner must be
completely replaced. Even if the belt
does not present any exterior signs
of wear or damage, it may have lost
its restraining properties.
Air bag Warning Light
The
warning light should illuminate
and remain lit for a few seconds bulb
checking when the key in the ignition
switch is turned inMAR (ON)position
(see “Supplemental Restraint System
(SRS) — Air bags” chapter in this
section).
•Ifthe

flickers, or comes on while driving,
have the system checked by an
Authorized Maserati Dealer.
Defroster
Check operation by selecting the
defrost mode and place the fan system
on high speed (see “Air Conditioning
Controls” chapter in section
“Dashboard Instruments and
Controls”).
You should be able to feel the air
directed against the windshield and
front side windows. Contact an
Authorized Maserati Dealerfor service
if your defroster is inoperable.
Floor Mat
Always use floor mats designed to fit
the footwell of your vehicle. Use only
floor mats that leave the pedal area
unobstructed and that are firmly
secured so that they cannot slip out of
position and interfere with the pedals
or impair safe operation of your
vehicle.
NOTE:
TheAuthorized Maserati Dealercan
provide you with any information
about the available Maserati floor
mats included in the “Genuine
Accessories” range.
WARNING!
Pedals that cannot move freely can
cause loss of vehicle control and
increase the risk of serious personal
injury.
•Always make sure that floor mats
are properly attached to the proper
fasteners.
•Never place or install floor mats or
other floor coverings in the vehicle
that cannot be properly secured to
prevent them from moving and
interfering with the pedals.
•Never put floor mats or other floor
coverings on top of already installed
floor mats. Additional floor mats and
other coverings will reduce the size
of the pedal area and interfere with
the pedals.
•Check mounting of mats on a regular
basis. Always properly reinstall and
secure floor mats that have been
removed for cleaning.
•Always make sure that objects
cannot fall into the driver footwell
while the vehicle is moving. Objects
can become trapped under the brake
pedal and accelerator pedal causing
a loss of vehicle control.

operation causing loss of control of
the vehicle.
Tires
• Examine tires for excessive tread
wear and uneven wear patterns.
• Check for stones, nails, glass, or
other objects lodged in the tread or
sidewall.
• Inspect the tread for cuts and cracks.
• Inspect sidewalls for cuts, cracks and
bulges.
• Check the wheel nuts for tightness.
• Check the tires (see “Tire Inflation
Pressure” chapter in section
“Features and Specifications”) for
proper cold inflation pressure.
Lights and Indicator Lights
• Have someone observe the
operation of exterior lights while
you operate the controls (see
“Lights” chapter in section
“Understanding the Vehicle”).
• Check turn signal and high beam
indicator lights on the instrumentcluster (see “Instrument Cluster”
chapter in section “Dashboard
Instruments and Controls”).

Cargo Area
WARNING!
To help protect against personal
injury, passengers must not be seated
in the rear cargo area. The rear cargo
space is intended for load carrying
purposes only, not for passengers,
who should sit in seats and use seat
belts.
Vehicle Load Carrying Capacity
The load carrying capacity of your
vehicle is shown on the “Tire and
Loading Information Label”
positioned on the rear driver door's
pillar.
The information indicated on the label
concerns passengers and luggage
loading operations.Do not exceed the specified Gross
Vehicle Weight Rating (GVWR) or the
Gross Axle Weight Rating (GAWR) for
either the front or rear axle.
The GVWR is the total allowable
weight of your vehicle. This includes
driver, passengers, and cargo.
The maximum load which may be
carried in the rear luggage
compartment is 66 lbs (30 kg).
WARNING!
Do not exceed the GVWR, or front or
rear GAWR. Exceeding these limits
may lead to poor handling, vehicle
instability or tire damage which could
cause a crash in which you or others
could be seriously injured or killed.
WARNING!
•Improper weight distribution can
have an adverse effect on the way
the vehicle steers, handles and the
way the brakes operate.
•Never drive with the trunk lid open.
Exhaust gases can enter the
passenger compartment.
The trunk is the most suitable place to
load bulky and heavy objects onboard
the vehicle.
To load your vehicle properly, store
heavier items below and be sure you
distribute their weight as evenly as
possible.
Stow all loose items securely before
start driving as they could move
during the trip.
Carrying Luggage on Rear
Seats
Light luggage may be transported on
the rear seats only if they are securely
anchored on the seats using the
tethers provided (upon request).

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).

Left Turn Signal Indicator Light
The indicator lights up when
the left turn signals or the
hazard flashers are turned on.
The indicator light will flash at
the same frequency of the turn signals
and is controlled by the left
multifunction lever.
If the vehicle electronics sense that the
vehicle drives for more than 1 mile
(1.6 km) with either turn signal on, a
continuous sound will alert the driver
to turn the signal off.
If the indicator flashes at a rapid rate,
check for a defective exterior light
bulb.
Rear Fog Light Indicator
This indicator lights up when
the rear fog lights are
switched on.
Tire Pressure Monitoring Light (*)
This indicator light is
connected to the Tire Pressure
Monitoring System (TPMS).
Under normal conditions, the
warning light should illuminate when
the key in the ignition switch is in
MAR (ON)position and should go off
as soon as the engine is started.
If the warning light remains lit or
illuminates while driving, the pressureof one or more tires is too low: the
related message will be displayed.
If the warning light flashes prior to
remain on, it indicates that the system
is temporarily unavailable.
This warning light illuminates even
when you calibrate the TPMS and
remains lit until the system is
calibrated.
Please refer to “Tire Pressure
Monitoring System (TPMS)” in section
“Driving” for further information.
Telltales on Tachometer
Following telltales are displayed on
the tachometer and related messages
are visible for 10 seconds on the
central sector of the display, unless
otherwise indicated (see “TFT Display”
in this chapter).Anti-Lock Brake Light (*)
This light, and its related
message, indicate possible
malfunctions of the Anti-Lock
Brake System (ABS).
The light will turn on when the key in
the ignition switch is inMAR (ON)
position and may stay on for 4
seconds. If the ABS light remains lit or
turns on while driving, the Anti-Lock
portion of the brake system is not
functioning and requires service.
However, the conventional brake
system will continue to operate
normally if the
indicator light is
switched off. If the ABS light turns on
while driving, or if it does not switch
on when the key in the ignition switch
is inMAR (ON)position, please visit as
soon as possible anAuthorized
Maserati Dealerin order to restore the
Anti-Lock brakes functions.
Seat Belt Reminder Light (*)
When the key in the ignition
switch is inMAR (ON)
position, the seat belt
reminder light will light up for
a few seconds as a bulb check.
During the bulb check, you will hear
an acoustic signal if one or both front
seat belts are unbuckled.
