•Never leave children alone in a
vehicle, or with access to an
unlocked vehicle.
•Allowing children to be in a vehicle
unattended is dangerous for a
number of reasons. A child or others
could be seriously or fatally injured.
Children should be warned not to
touch the parking brake switch,
brake pedal or the shift lever.
•Do not leave the key in or near the
vehicle, and do not leave the key in
the ignition switch in the ACC or
MAR (ON) position. A child could
operate power windows, other
controls, or move the vehicle.
•Do not leave children or animals
inside parked vehicles in hot
weather. Interior heat build-up may
cause serious injury or death.
•An unlocked car is an invitation to
thieves. Always remove the key
from vehicle, cycle the ignition
switch to STOP (OFF) and lock all
doors when leaving the vehicle
unattended.
•In the event of tampering with the
starter switch (e.g. attempted theft),
have it checked by an Authorized
Maserati Dealer before restarting
the vehicle.The key can be removed from the
ignition switch only when the
transmission shift lever is in position P
(Park).
If the transmission shift lever is shifted
to P (Park) after turning off the
engine, the key can only be removed
within 30 seconds from turning it to
STOP (OFF)position.
If you do not remove the key within
30 seconds, you will need to turn it
back toMAR (ON)and then toSTOP
(OFF)position to have a further 30
seconds within which to remove the
key.
In the event that the key unlocking
system fails or if it is not possible to
shift the transmission shift lever to P
(Park) position, to remove the key
from the ignition switch you must turn
it toSTOP (OFF)position, then:
• remove the cap indicated in the

drive as well as when parking and
leaving the vehicle unattended.
•When leaving the vehicle, always
remove the key and lock your
vehicle.
•Do not allow children to be in a
vehicle unattended or with access to
an unlocked vehicle. A child or
others could be seriously or fatally
injured. Children should be warned
not to touch the parking brake
trigger, brake pedal or the shift
lever.
•Do not leave the key in or near the
vehicle, and do not leave ignition
switch in the ACC or MAR (ON)
position. A child could operate

• how far (if at all) the driver was
depressing the accelerator and/or
brake pedal; and
• how fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur.
NOTE:
EDR data are recorded by your vehicle
only if a non-trivial crash situation
occurs; no data are recorded by the
EDR under normal driving conditions
and no personal data (e.g., name,
gender, age, and crash location) are
recorded. However, other parties, such
as law enforcement, could combine
the EDR data with the type of
personally identifying data routinely
acquired during a crash investigation.
To read data recorded by an EDR,
special equipment is required, and
access to the vehicle or the EDR is
needed.
In addition to the vehicle
manufacturer, other parties, such as
law enforcement, that have the
special equipment, can read the
information if they have access to
vehicle or the EDR.Active Roll Bars
The active roll bars that equip the
vehicle have been designed for
protecting passengers in the event of
a vehicle rollover.
They are fitted behind the rear seat
headrests, usually in a hidden position,
and are activated by a specific ECU
which, only in the case of high-severity
rollover, deploys them in a few tenths
of a second. A cross member then
locks them in this position.
The roll bars have been designed in
such a way that they can be fully
deployed also with the soft top closed.
This is ensured by a device which
breaks the rear window when it comes
in contact with it.
In combination with the windshield
outer frame, they help creating an
anti-intrusion safety cell.In addition to being deployed in the
case of rollovers around the vehicle
longitudinal axis (as shown in the
figure) the active roll bars activate as a
precautionary measure in the event of
sufficiently severe side and rear
collisions, and in all cases where the
battery might be disconnected. They
do not activate in the event of
spinning.
WARNING!
•The active roll bars do not prevent
the risk of the occupants being
thrown out of the vehicle or hitting
against its internal structures. Only
the seat belts are designed for these
purposes and must always be
properly fastened when traveling.

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.

Vehicle Safety Checks
Seat Belts
• Inspect the belt system periodically,
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
warning light does not
illuminate while starting, contact an
Authorized Maserati Dealer.•Ifthe
warning light stays on,
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.

•Mounting posts must be properly
installed, if not equipped from the
factory. Failure to properly follow
floor mat installation or mounting
can cause interference with the
brake pedal and accelerator pedal
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”).
Door Latches
• Check for positive closing, latching,
and locking of doors and trunk lid
(see chapter “Doors” and “Open and
Close the Trunk Lid” in this section).
Fluid Leaks
• Check area under vehicle after
overnight parking for recent fluid
leaks (oil, fuel, etc.).
• If gasoline fumes are detected or
fluid leaks are suspected, contact an
Authorized Maserati Dealer.
