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

Vehicle Security Alarm The vehicle security alarm system
performs the following functions:
• remote control of the centralized
door locking/unlocking system;
• perimeter surveillance, detecting the
opening of doors, engine/trunk
compartment lids;
• motion surveillance, detecting
intrusion in the passenger
compartment;
• vehicle movement surveillance.
NOTE:
The engine immobilizer operation is
guaranteed by the Maserati CODE
system, which is automatically
activated when the key is removed
from the ignition switch.
Alarm System Activation Press the lock button on the key to
activate the security alarm system. • The turn signals flash once.
• The system beeps.
• The red LEDs on the front door
panels flash.
• The vehicle centralized door locking
is activated and the doors are locked.
The system becomes operative after
approximately 25 seconds and the
alarm is activated when:
• a door is opened;
• the trunk compartment lid is opened;
• the engine compartment lid is
opened;
• someone attempts to enter the
vehicle from a window;
• the power supply is disconnected;
• the siren is disconnected;
• the vehicle is moved.
When the vehicle security alarm is
active, the user may request the trunk
compartment opening; in this case, the motion and inclination sensors are
temporarily deactivated.
If the trunk compartment lid is then
closed, the sensors will be reactivated.
Should the turn signals flash 9 times
when you activate the security alarm
system, this means that one of the
doors or lids is not properly closed and
therefore is not protected by the
perimeter surveillance.
Check for correct closing of doors,
engine/trunk compartment lids and
close the open one without
deactivating the security alarm system:
the turn signals flashing once indicate
that now the door, engine/trunk
compartment lids are closed properly
and are protected by the perimeter
surveillance.
CAUTION!
If the turn signals flash 9 times when
the security alarm system is activated
with doors, front and rear lids properly
closed, this means that the
self-diagnostic function has detected a
malfunction in the system and that
you should contact an Authorized
Maserati Dealer to have the system
checked.Before 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
