ALFA ROMEO
CODE SYSTEMTo increase protection against attempted
theft, the car is fitted with an electronic en-
gine lock system (Alfa Romeo CODE) which
is activated automatically when the ignition
key is removed. In fact the grip of each key
contains an electronic device which modu-
lates the radio frequency signal transmit-
ted when the engine is started by a special
aerial incorporated in the ignition switch. This
modulated signal is the “password” by
which the control unit recognises the key
and only in this condition can the engine
be started.
THE KEYSThe car is delivered with two keys, key
(A-fig.1) with metal insert and remote
control function and another key with metal
insert only, without remote control.
The key remote control operates:
– door centralised opening/locking
– opening luggage compartment boot/
tailgate
– activation/deactivation of electronic
alarm (if existing)

WARNINGIn order to ensure perfect ef-
ficiency of the electronic devices contained
inside the keys, they should never be directly
exposed to the rays of the sun.
If the car changes owner,
the new owner must be
given all the keys and the
CODE card.

The CODE card (fig. 2) is also supplied
with the key and it contains the codes of the
keys (both the mechanical one and the elec-
tronic one for emergency starting).
The code numbers on the CODE card must
be kept in a safe place, not in the car.
The driver should always keep the elec-
tronic code given on the CODE card with him
in the event of having to carry out emer-
gency starting.
KEY WITH REMOTE CONTROLThe key with remote control (fig. 3) is
fitted with:
– a metal insert (A) that can be enclosed
in the key grip
– button (B) for remote opening/clos-
ing of the doors and turning the electronic
alarm on/off (where fitted)
– a button (C) for remote boot unlock-
ing

WARNINGCertain radio devices outside
the car (e.g. mobile phones, HAM radio sys-
tems) could disturb the remote control fre-
quency. In this case the remote control could
malfunction.
OPENING THE BOOTThe boot can be opened by remote control
from outside pressing button (C-fig. 3),
also when the electronic alarm (where fit-
ted) is on.
In this case the alarm system switches off
the boot volumetric protection and control
sensor, the system gives two “beeps” (with
the exceptions of versions for certain mar-
kets) and the direction indicators light up for
about three seconds.
Closing the boot again, the control func-
tions are restored, the system gives two
“beeps” (with the exceptions of versions for
certain markets) and the direction indicators
light up for about three seconds. The metallic insert (A) of the key oper-
ates:
– the ignition switch
– the driver's door lock and, optional for
versions/markets where applicable, the pas-
senger's door lock
– passenger’s Air bag deactivation.
To move the metallic insert out of the key
grip, press button (E).
When button (E) is
pressed, take the utmost
care to prevent the metal insert
from causing injury or damage
when it comes out. Button (E) must
only be pressed when the key is
away from the body, in particular
the eyes, and from objects that
could be spoilt (e.g. clothes). Never
leave the key unattended to pre-
vent anyone, especially children,
from holding it and pressing button
(E) inadvertently.

ELECTRONIC ALARM(optional for versions/markets
where applicable)DESCRIPTIONThe system comprises: transmitter, re-
ceiver, control unit with siren and volumet-
ric sensors and anti-lift sensor. The electronic
alarm is controlled by a receiver inside the
car and it is turned on and off through the
remote control incorporated in the key which
sends the crypted and variable code. The
electronic alarm monitors: unlawful opening
of the doors, bonnet and boot (perimetral
protection), operation of the ignition key,
battery and emergency key cable cutting,
the presence of moving bodies (volumetric
protection), any abnormal raising/sloping
of the car (for versions/markets where ap-
plicable) and operates the central door lock-
ing system. It also makes it possible to cut
off the volumetric protection.
WARNINGThe engine inhibitor function
is guaranteed by the Alfa Romeo CODE sys-
tem which is activated automatically when
the ignition key is removed.

REQUEST FOR ADDITIONAL
KEYS WITH REMOTE CONTROLThe receiver can recognise up to 5 keys
with remote control. If during the life of the
car a new key with remote control is needed
for any reason whatsoever, contact Alfa
Romeo Authorized Services directly, taking
with you the CODE card, a personal iden-
tity document and the car’s possession doc-
uments.
ACTIVATING THE ALARMWhen the doors and boot/bonnet lids are
closed and the ignition key is in the STOP
or PARKposition (key removed), point the
remote control towards the car and then
press and release the button (B-fig. 8).
With the exception of some markets the
system sounds a beep and the door lock is
engaged.
Engagement of the alarm is preceded by
a self-diagnosis phase characterised by a
change in the frequency at which the de-
terrent led (A-fig. 9) on the dashboard
flashes. If an anomaly is detected the sys-
tem gives off a further beep.fig. 9
A0B0563m
Surveillance
When the system has been turned on, the
led (A-fig. 9) on the dashboard will flash
to indicate that the system is in the surveil-
lance mode. The led will flash continuously
while the system is under surveillance.
WARNINGOperation of the electronic
alarm is adapted at the origin to the regu-
lations of the different countries.

AUTOMATIC ENGAGEMENT
OF THE ALARM (optional for versions/markets
where applicable)
If the alarm has not been engaged with
the remote control it will come on auto-
matically after an established time of 30
seconds from the moment that the ignition
key has been turned to the STOPor
PARKpositions and a door or the boot has
been opened and then closed again. This
condition is shown by the intermittent illu-
mination of the led in the car and by the sig-
nalling described previously.
To deactivate the alarm press the button
on the remote control.
The alarm is also automatically engaged
when the doors are closed using the key.
When the alarm is engaged automatically
the doors are not locked.
WHEN THE ALARM
IS TRIGGEREDWhen the alarm is engaged it will sound
when:
– one of the doors, the bonnet or the tail-
gate is opened;
– the battery is disconnected or the elec-
tric cables are cut, or the emergency key ca-
bles are cut;
– intrusion into the passenger compart-
ment, e.g. window being broken (volumetric
protection);
– attempt to start the engine (key at
MAR);
– abnormal car raising/sloping (for ver-
sions/markets where applicable).
Depending on the markets, the triggering
of the alarm will activate the siren and the
hazard warning lights (for about 26 sec-
onds). The methods of operation and the
number of cycles may vary depending on
the versions/markets.
However a maximum number of cycles is
foreseen.
Once the alarm cycle has come to an end,
the system will return to its normal moni-
toring state.
INTERRUPTING THE ALARMTo interrupt the alarm press the button on
the remote control or, if the remote control
battery is down, get into the car, insert the
key into the ignition switch and turn the key
to MAR.
WARNINGIf it is necessary for the ve-
hicle to lie inactive for long periods (over 3
weeks), close the vehicle using the key to
deactivate the alarm.

MINISTERIAL HOMOLOGATIONIn keeping with the laws in force in each
country on the subject of radio frequency,
we point out that:
– the separate homologation numbers for
each market are given on the last pages of
this handbook before the alphabetical index
(for some countries also homologation doc-
ument);
– for markets in which the transmitter
needs to be marked with the homologation
number, this has been stated on the com-
ponent.
(Depending on the versions/markets, the
code may also be marked on the transmit-
ter and/or on the receiver).
