OPERATION
(fig. 4)
Each time the ignition key is turned to
STOPposition, the Alfa Romeo CODE sys-
tem deactivates the functions of the engine
electronic control unit.
Each time the engine is started, turning the
key to the MARposition, the control unit
of the Alfa Romeo CODE system sends a
recognition code to the engine control unit
to deactivate the inhibition of the functions.
The recognition code, which is crypted and
variable between over 4 billion combina-
tions, is only sent if the system control unit
has recognised the code sent to it by the
key, which contains an electronic transmit-
ter, through an aerial in the ignition switch.This condition is indicated by a brief flash
of the warning light (A) on the check panel.
If the code has not been recognised cor-
rectly, the warning light (A) stays on to-
gether with the warning light (B).
In this case, you are recommended to re-
turn the key to the STOPposition and then
back to MAR; if the inhibition persists, try
again possibly with the other key provided
with the car. If it is still impossible to start
the car carry out the emergency starting pro-
cedure described in section “In an emer-
gency” and turn to an Alfa Romeo Autho-
rized Service.
WARNINGEvery electronic key has its
own code, which must be memorised by the
system control unit. To memorise new keys,
up to a maximum of eight, apply solely to
Alfa Romeo Authorized Services taking with
you all the keys in your possession, the
CODE card, a personal identity document
and the car’s possession documents.

The codes of the keys not
provided during the new
memorising procedure are
erased from the memory. This is to
ensure that any lost or stolen keys
can no longer be used to start the
car.
WARNINGThe Alfa Romeo CODE
Y
warning light comes on when travelling with
the ignition key on MAR:
1)If the warning lamp lights up while the
car is moving, it means that the system is
running a self-diagnosis (e.g. due to a volt-
age drop). The first time you stop you can
test the system as follows: switch the en-
gine off by turning the ignition key to
STOP; then turn the key back to MAR:
the warning lamp will light up and should
go out in the space of about one second. If
the warning lamp fails to go out, leave the
key at STOPfor more than 30 seconds and
repeat the procedure described previously.
If the problem persists, contact your Alfa
Romeo Authorized Service.

2)If the warning lamp flashes it means
that the car is not protected by the immo-
biliser. Contact your Alfa Romeo Authorized
Service immediately and get them to store
the codes of all the keys in the memory.
CHANGING THE BATTERY
OF THE KEY WITH REMOTE
CONTROLIf when pressing button (Bor C-fig. 5)
the control is rejected or is not performed,
the battery should be replaced by a new one
of the same type to be found c/o normal
retailers. On versions fitted with electronic
alarm, the need to replace the remote con-
trol battery is indicated by the coming on,
with fixed light, of the deterrent led set on
the dashboard near the central air vent. If after 2 seconds with
the key in the MAR posi-
tion, the warning light turn
on again flashing, this means that
the code of the keys has not been
memorised, thus the car is not pro-
tected by the Alfa Romeo CODE
system against attempted theft. In
this case, contact an Alfa Romeo
Authorized Service to have the key
codes memorised.
Dead batteries are harm-
ful for the environment.
They must be disposed of
in special containers as specified by
current regulations. Avoid expo-
sure to naked flames and high tem-
peratures. Keep out of reach of
children.

WARNINGThe system is protected by
a 10 A fuse housed in the fuse-holder set
under the dashboard (see paragraph “If a
fuse or relay blows” in the chapter “In an
emergency”).

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

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.

Self-diagnosis and monitoring
of doors and bonnet/boot
If, after the alarm has been activated, a
second acoustic signal is heard, check that
all the doors and bonnet/boot are closed
properly and engage the system once again.
On the other if a door or bonnet/boot lid
is not correctly closed it will not be controlled
by the system.
If the control signal is repeated when the
doors and bonnet/boot are closed properly
this means that the self-diagnosis function
has detected a system operating fault, in
which case it is necessary to contact Alfa
Romeo Authorized Services.
DEACTIVATING THE ALARMTo deactivate the alarm, press the button
on the key with remote control. The system
performs the following (with the exception
of some markets):
– the direction indicators turn on twice
briefly
– two beeps are sounded briefly by the
siren
– the doors are released.
WARNINGIf the led (A-fig. 9) in the
car stays on when the system has been de-
activated, (maximum of 2 minutes or until
the ignition key is moved to MAR) the fol-
lowing should be borne in mind:
– if the led stays on permanently, it means
that the remote control batteries are flat and
need replacing;– if the led continues to flash, but at dif-
ferent intervals than normal, it means that
attempts to steal the car have been made,
counting the number of flashes it is also pos-
sible to identify the type of attempt:
1 flash: right front door
2 flashes: left front door
3 flashes: right rear door
4 flashes: left rear door
5 flashes: volumetric sensors
6 flashes: bonnet
7 flashes: boot
8 flashes: tampering with car starting
cables
9 flashes: tampering with battery or
cutting emergency key ca-
bles
10 flashes: at least three causes of
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).
REMOTE CONTROL
DOOR LOCKING SYSTEMThe system comprises a receiver inside the
car and a transmitter (remote control) in-
corporated in the key (E-fig. 11).
To lock/unlock the locks, point the trans-
mitter towards the car, press and release the
button (B-fig. 11).WARNINGShould it be necessary to
