Immobilizer System The Maserati CODE System In order to increase protection against
theft, the vehicle is equipped with an
electronic engine immobilizer system
(Maserati CODE), which is
automatically activated when the key
is removed from the ignition switch.
Each starter key contains an electronic
device which transmits a code signal to
the Maserati CODE control unit, and
engine ignition is enabled only if the
key code is recognized by the system.
Using the key inserted in the driver's
outboard door lock, you can also
control the soft top opening/closing
strategy referred to as “Summer
open”. This strategy is described in
chapter "Soft Top" of section
"Understanding the Vehicle".
Key Codes A CODE card is supplied with the keys.
This card indicates the following:
• the “ELECTRONIC CODE” to be used
for emergency starting (see
"Emergency Starting with Maserati
Code" in section "In an Emergency");
• the “MECHANICAL CODE” to be
provided to an Authorized Maserati Dealer if you request duplicates of
the keys.
NOTE:
• The code numbers shown on the
CODE card should be kept in a safe
place.
• You are advised to always keep the
CODE card number with you, as it is
absolutely necessary in the event of
“Emergency Starting”.
• In the event of a vehicle ownership
transfer, it is essential that the new
owner is provided with all the keys
and with the CODE card.
• It is advisable to write down and
keep the codes listed on the plates
delivered with the keys and the
remote control in a safe place (not in
the vehicle) in order to request
duplicates if needed. CODE System Operation Each time the key in the ignition
switch is removed in the STOP (OFF)
position, protection system activates
the engine immobilizer.
When the engine is started and the
key is turned to MAR (ON) position:
• If the code is recognized, the CODE
warning light on the instrument
cluster turns off within a second,
while the MIL
warning light,
once the ECU diagnosis has been
completed, goes off after about four
seconds. In these conditions, the
protection system recognizes the key
code and deactivates the engine
immobilizer. When the key in the
ignition switch is turned to AVV
position, the engine starts.
• If the CODE
warning light
remains on and the MIL
warning
light goes off after four seconds (ECU
diagnostics) and illuminates again
immediately afterward, the code has
not been recognized and the
message “Electronic key not
recognized” is displayed. If this
occurs, turn the key in the ignition
switch to STOP (OFF) and then back
to MAR (ON) position. If the
immobilizer stays on, try with the
other keys. If you still cannot startBefore Starting

Alarm System Deactivation Press the lock button on the key to
activate the security alarm system.
• The turn signals flash twice.
• The system emits a double beep.
• The red LEDs on the front door
panels turn off.
• The centralized door locking system
is activated and the doors are
unlocked.
The security alarm system is off and it
is therefore possible to get into the
vehicle and start the engine.
Pressing the
unlock button twice
unlocks the doors and also switches on
the low beams for 30 seconds.
NOTE:
The security alarm system is not
deactivated when the key is turned in
the locks. Getting into the Vehicle with
Alarm On When the battery on the radio control
case is dead, to access the vehicle you
must insert the key in the lock on one
of the two front doors and turn it
clockwise to unlock it.
The alarm will sound but you will have
to continue with the normal starting
procedure. The alarm will turn off.
Anti-intrusion and Anti-lift
Protection The anti-intrusion/anti-lift alarm
device may be deactivated by pressing
the button, on the dome console,
when the key in the ignition switch is
in MAR (ON) position or within 1
minute from turning the engine off
(key in the STOP (OFF) position).
Deactivation is signaled by the LED on
the button flashing for 3 seconds. CAUTION!
Anti-intrusion and anti-lift protections
override is memorized until the alarm
is next activated: therefore, if these
protections are overridden but the
alarm is not activated immediately, the
override will remain memorized until
the next time it is activated, regardless
of turning the vehicle on/off.
Security Alarm Memory If the CODE warning light appears
on the display when the vehicle is
started, accompanied by the message
“Break-in attempt detected” this
means that an intrusion has been
attempted during your absence.
The security alarm system memory is
reset when you turn the ignition key.Before Starting

Reset Auto-Up/Down Should the auto-up/down feature stop
working, the window probably needs
to be reset.
To reset auto-up/down, pull the
window switch up to close the
window completely and push the
window switch down to open the
window completely.
If You have to Disconnect the
Battery Before disconnecting the battery,
lower the side windows by at least 1-2
in (4-5 cm) to avoid damaging the soft
top strip when opening and closing
the door.
When the battery is connected, this
operation is performed automatically
when the door is opened and closed.
The windows must remain lowered
until the charged battery is
reconnected. If the battery is
completely discharged when the
windows are fully raised, only open
the door if absolutely necessary, with
the utmost care; do not close the door
again until it is possible to lower the
window. Open and Close the Trunk
Lid Opening The trunk compartment lid can be
opened from inside or outside the
vehicle.
Button which opens the lid from
inside, is located to the left of the
steering wheel.
It can only be operated when the key
is removed from the ignition switch or
turned to STOP (OFF) or ACC position.
To open the trunk compartment lid
from outside, press button on the
radio control case: this opens the lock
and the trunk lid rises slightly. To open the trunk lid from the
outside, when the security alarm is
deactivated and the key is inside the
vehicle, simply press the button
underneath the license plate light
frame.
To avoid accidental activation while
the vehicle is moving, it is only
possible to open the trunk
compartment when the key is
removed from the ignition switch or
turned to STOP (OFF) or ACC position.Before Starting

Lift the hood completely: this
operation is facilitated by two gas
struts keeping the fully open position.
With the key in the ignition switch in
MAR (ON) position, the specific red
warning light will display on the
instrument cluster with the message
indicating that the hood is open (see
chapter “Instrument Cluster” in section
“Dashboard Instrument and
Controls”).
Closing Lower the hood to about 20 cm (8 in)
from the contact area of the engine
compartment and then drop it. This
should secure the inclusion of the
latch. CAUTION!
To prevent possible damage, do not
slam the hood to close it.
WARNING!
• Be sure the hood is fully latched
before driving your vehicle. If the lid
is not fully latched, it could open
when the vehicle is in motion and
block your vision. Failure to follow
this warning could result in serious
injury or death.
• Gear shifting is always active and
may be performed even when one
or more doors, the hood or the trunk
lid are open. Therefore, in these
conditions, take great care to avoid
moving the transmission shift lever
and so accidentally engage gears. Occupants Restraint
Systems The listed occupants restraint systems
are some of the most important safety
features in your vehicle:
• Three-point seat belts (also called lap
and shoulder belts) for the driver and
all passengers.
• Front air bags for driver and
passenger.
• Seat-mounted side air bags for the
driver and front passenger.
• An energy-absorbing steering
column and steering wheel.
• Front seat belts incorporate a
pretensioner (Emergency Tensioning
Device - ETD) that may enhance
occupant protection by managing
the energy created during an impact.
• Front seat belt retractors are
equipped with load limiting devices
which control the seat belt reeling
out so as to adjust the force exerted
on the shoulders while the seat belt
is in restraining mode.
• All seat belts system (except the
driver’s) include Automatic Locking
Retractors (ALR), which lock the seat
belt webbing into position by
extending the belt all the way outBefore Starting

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).Understanding the Vehicle

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 in MAR (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 a preset 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
an Authorized 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 to STOP
(OFF) position and then restart the
engine.Understanding the Vehicle

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 pressure of 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 in MAR (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 in MAR (ON) position, please visit as
soon as possible an Authorized
Maserati Dealer in order to restore the
Anti-Lock brakes functions.
Seat Belt Reminder Light (*)
When the key in the ignition
switch is in MAR (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.Dashboard Instruments and Controls
