Reprogramming a single key

If you want to program activation 
of a new system on an already used 
HomeLink key, proceed as follows:
-  press and hold down the HomeLink 

key selected;

-  after about 20 seconds, the LED T 

starts flashing; keep the key pressed 
down;

-  hold the original remote control of 

the device to be controlled close to 
the HomeLink control panel (12 in);

-  press and hold down the original 

remote control key;

-  successful programming is signaled 

by the LED T flashing faster; 

-  release both keys.
The system previously programmed 
on HomeLink has thus been replaced 
with the new programming and is 
ready to be used. 
This operation has no impact on the 
other HomeLink keys.

Unlike programming which is done 
for each individual key, deletion is 
done for all three keys simultaneously. 
To delete, proceed as follows:
-  press and hold down the keys Q 

and S;

-  after about 20 seconds, the LED T 

starts flashing;

-  release the keys.

WARNING: It is advisable to carry out 
the HomeLink deletion procedure 
when you intend to sell the vehicle.

When the alarm system is turned on 
and the doors are locked, the LEDs on 
the doors flash.
The remote control allows you to 
operate the centralized opening of all 
the doors or of the driver’s door only, 
depending on the Multi Media System 
settings. When locking the doors from 
the outside, if one or more doors 
are not properly closed they will 
not be locked, while if the luggage 
compartment is not properly closed, 
the doors will always lock.
In both cases, the malfunction will be 
indicated by the direction indicators 
flashing for a few seconds.

WARNING: The interior buttons for 
door locking/unlocking, luggage

closing.

B  - Front right-hand window 

opening/closing.

Press the button for the driver’s 
window A, with the ignition key to 
MAR (ON), to activate automatic 
operation: the window is closed when 
it reaches the upper limit (or pressing 
the button again). 

WARNING: If the power window is 
activated with the door open, the 
window stops before reaching the 
upper limit, to prevent interference 
with the weather strip when the door 
is closed.

When the door is opened, 
the window is slightly 
lowered and then closes 

automatically after the door is closed: 
take the greatest care to avoid 
passengers (especially children) being 
near the windows when opening/
closing the doors.

Improper use of the power 
window controls can be 
dangerous. Check that 

passengers are away from the side 
windows before closing them. 
Always remove the ignition key when 
you get out of the vehicle, in order 
to avoid accidental activation of the 
power windows - they represent a 
hazard for passengers remaining in 
the vehicle.

Leaving children in a parked 
vehicle with the windows 
shut is dangerous: the 

temperature inside the vehicle 
can reach very high levels, causing 
fainting and serious injuries. 

WARNING: Before disconnecting 
the battery, lower the side windows 
by at least 1-2 in (4-5 cm) to avoid 
damaging the weather strips when 
opening and closing the doors. 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 discharged 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.

WARNING: Before activating the 
alarm system, check that all the 
windows and the sunroof are closed 
to prevent accidental activation of the 
alarm system.

Keys

The Maserati CODE system 

In order to help increase protection 
against theft, the vehicle is equipped 
with an electronic engine immobilizer 
system (Maserati CODE), which is 
automatically activated when the 
ignition key is removed.
Each ignition 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 
acknowledged by the system.
Two keys are supplied with the 
vehicle. 
The key is used for:
-  starting the engine
-  activating the central door locking 

system

- deactivating/activating 

the 

passenger airbag (on vehicles 
equipped with manual deactivation 
system) 

-  opening the luggage compartment 

lid electrically 

-  activating/deactivating the alarm 

system

-  locking/unlocking the glove 

compartment.

Operation

Each time the ignition key is removed 
from the STOP (OFF) position, the 
protection system will activate the 
engine immobilizer.
When the key is turned to MAR (ON), 
upon engine start-up:
1) If the code is acknowledged, the 

CODE warning light 

 on the 

instrument panel will turn off within 
a second, while the OBDII warning 
light 

, once the ECU diagnosis 

cycle has been completed, will turn 
off after about 18 seconds. If these 

conditions are met, the protection 
system recognizes the key code and 
deactivates the engine immobilizer. 
Turn the key to start the engine.

2) If the CODE warning light 

 stays 

on and the OBDII lamp 

, goes off 

after 18 seconds and then comes on 
again immediately, the code is not 
recognized. If this occurs, turn the 
key to STOP (OFF) and then back to 
MAR (ON). If the immobilizer stays 
on, try with the other keys. If you 
still cannot start the engine, try the 
emergency start procedure (see on 
page 174) and contact your local 
Authorized Maserati Dealer.

When driving with the ignition key in 
the MAR (ON) position:

1) If the CODE warning light 

 

illuminates, it means that the system 
is performing a self-diagnostic 
cycle. At the first stop, you can 
test the system: turn the ignition 
key to STOP (OFF) the engine and 
then back to MAR (ON). The CODE 
warning light 

 will come on and 

should turn off in approximately 
one second. If the warning light 
stays on, repeat the procedure 
described previously leaving the 
key at STOP (OFF) for more that 30 
seconds. If the malfunction persists, 
contact your local Authorized 
Maserati Dealer.

2) If the CODE warning light 

 flashes, it means that the 

vehicle is not protected by the 
immobilizer device. Contact your 
local Authorized Maserati Dealer 
immediately to have the codes of 
all the keys restored in the memory.

WARNING: Strong impacts can 
damage the electronic components in 
the key.

WARNING: Each key has its own 
specific code, which must be stored 
in the memory of the system control 
unit.

Duplicating the keys

When ordering additional keys, 
remember that the memorization 
procedure (up to maximum of 7 
keys) must be performed on all the 
keys, including those already in 
your possession. Contact your local 
Authorized Maserati Dealer directly, 
bringing with you all the keys in your 
possession, the Maserati CODE system 
CODE CARD, the electronic alarm 
system CODE CARD, a personal ID and 
the identification and registration 
documents proving ownership of the 
vehicle. The codes of any keys that are 
not available when the new storage 
procedure is performed will be erased 
from the memory to prevent any lost 
or stolen keys being used to start the 
vehicle.

Emergency starting

If the MASERATI CODE fails to 
deactivate the engine immobilizer, 
the CODE warning light 

 will 

illuminate permanently, the OBDII 
warning light 

 will turn off after 

four seconds and then will illuminate 
immediately and the engine will 
not start. To start the engine, it is 
necessary to follow the emergency 
start procedure.

WARNING: We recommended that 
you read the entire procedure before 
carrying it out. If you make a mistake, 
you should turn the ignition key to 
STOP (OFF) and repeat the operations 
from step 1.

light 

 illuminates for 4 seconds 

and then goes off. You can now 
release the accelerator pedal.

8) A quick flashing of the OBDII 

warning light 

 (about 4 seconds) 

confirms that the operation has 
been performed correctly.

9) Start the engine turning the key 

from MAR (ON) to AVV (START).

  If the OBDII warning light 

 

remains on, turn the key to STOP

Electronic alarm system 
device

The electronic alarm system performs 
the following functions:
-  remote control of the centralized 

door locking/unlocking system 

-  perimeter surveillance, detecting 

the opening of doors, engine/
luggage compartment lids 

-  motion surveillance, detecting 

intrusion in the passenger 
compartment

-  vehicle movement surveillance.

WARNING: The engine immobilizer 
function is ensured by the Maserati 
CODE system, which is automatically 
activated when the key is removed 
from the ignition switch.

Activation

Press button A on the key to activate 
the alarm system:
-  the direction indicators 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 luggage 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 electronic alarm is active, 
the user may remotely open the 
trunk. In this case, the motion and 
anti-lift sensors are temporarily 
deactivated. 
If the luggage compartment is then 
closed, the sensors will be reactivated.

Should the direction indicators flash 
9 times when you activate the 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/
luggage compartment lids and close 
the open one without deactivating 
the alarm system: the direction 
indicators flashing once indicate 
that now the door, engine/luggage 
compartment lids are closed properly 
and are protected by the perimeter 
surveillance.

WARNING: If the direction indicators 
flash 9 times when the 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 your 
Authorized Maserati Dealer to have 
the system checked.

Deactivation

Press button B on the key to 
deactivate the alarm system:
-  the direction indicators 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 alarm system is off and it is 
therefore possible to enter the vehicle 
and start the engine.

Pressing button B twice unlocks the 
doors and also turns on the low 
beams for 30 seconds.

WARNING: The alarm system is not 
deactivated when the key is turned in 
the locks.

Getting into the vehicle when 
the alarm system is on

When the remote control battery 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 can continue with the 
normal starting procedure (see page 
132). The alarm will turn off.
