•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.
WARNING!
California Proposition 65
Operating, servicing and maintaining
a passenger vehicle or off-road vehicle
can expose you to chemicals including
such as, engine exhaust, carbon
monoxide, phthalates and lead, that
which are know to the State of
California to cause cancer and birth
defects or other reproductive harm. To
minimize exposure, avoid breathing
exhaust, do not idle the engine except
as necessary, service your vehicle in a
well-ventilated area and wear glovesor wash your hands frequently when
servicing your vehicle. For more

this problem let more air into the
passenger compartment.
• It is advisable to close the soft top
when parking the vehicle. This not
only protects the passenger
compartment against weather
agents, but is also a safeguard
against theft.
• If possible, park in the shade as
prolonged exposure to the sun will
alter the canvas fiber and color.
• Before disconnecting the battery,
lower the side windows by about 1.6
- 2 in (4 - 5 cm) to prevent damaging
the soft top strip when the doors are
opened and closed. When the
battery is connected and fully
charged, this operation is performed
automatically whenever the doors
are opened or closed. The windows
must remain lowered until the
recharged battery is reconnected. If
the battery is dead and the windows
are fully up, only open the doors
when strictly necessary and being
extremely careful: do not close them
again until the windows can be
lowered.
• Cover the soft top with a protective
cloth when it is going to be parked
outdoor for a long period of time.• To avoid damaging the soft top, the
vehicle must not be washed with
high-pressure water jet systems, be it
a manual nozzle or an automatic car
wash with turning rollers.
• Organic residues must be
immediately removed, as they may
damage both the soft top fabric and
its strips.
• Do not use solvents, alcohol, petrol
or other generic detergents to clean
the soft top.
"Summer open" Strategy
Using the key inserted in the external
driver's door lock, you can control the
soft top opening/closing strategy
referred to as “Summer open”.
NOTE:
•The opening and closing cycle can be
interrupted at any time, moving the
key back to its initial position.
•The following operations are
performed with the engine off. This
involves an extremely high power
consumption, which causes the
battery to discharge faster.
With the soft topfully closed:
• insert the key in the external driver’s
door lock;• turn the key clockwise until
unlocking the doors and hold it in
this position. The automatic soft top
opening cycle will begin after
approx. 2 seconds;
• do not move the key for the entire
opening cycle.
With the soft topfully open:
• insert the key in the external driver’s
door lock;
• turn the key counterclockwise until
locking the doors and hold it in this
position. The automatic soft top
closing cycle will begin after approx.
2 seconds;
• do not move the key for the entire
closing cycle.

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.
