KEY BATTERY CHANGE
If pressing the remote control buttons
(AorB-fig. 7), the led (C-fig. 7)
(where required) gives only one brief
flash and the alarm system led (where
fitted) (A-fig. 8) on the dashboard s-
tays on glowing steadily for about 2 min-
utes (after turning off the alarm and with
the ignition switch off), it is necessary to
replace the battery with a new one of the
equivalent type to be found c/o normal
retailers.
To replace the battery, remove the plas-
tic lid (A-fig. 9), insert the new battery
according to the correct polarity and put
the lid back on.For further information contact Autho-
rised Alfa Romeo Services.
OPERATION
Each time the ignition key is turned to
theSTOPposition, the Alfa Romeo
CODE system 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 com-
binations, is only sent if the system con-
trol unit has recognised the code sent to
it by the key, which contains an electronic
transmitter, through an aerial in the igni-
tion switch. Dead batteries consti-
tute a hazard for the
environment and must
be disposed of in the special con-
tainers as specified by the rela-
tive laws.

This condition is indicated by a brief
flash of the warning light (A-fig.
10) on the check panel.
If the code has not been recognised cor-
rectly, the Alfa Romeo CODE system
warning light (A-fig. 10) stays on
together with the EOBD/fuel supply-igni-
tion system failure warning light (B-fig.
10) .
In this case, you are recommended to re-
turn the key to the STOPposition and
than back to MAR; if the inhibition per-
sists, 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 procedure described herein and
turn to an Alfa Romeo Authorized Service.
U
¢
¢IMPORTANTEvery electronic key has
its own code, which must be memorised
by the system control unit. To memorise
new keys, up to a maximum of seven,
apply solely to Alfa Romeo Authorized
Services taking with you all the keys in
your possession, the CODE card, a person-
al identity document and the car’s posses-
sion documents.
The codes of the keys
not provided during the
new memorising proce-
dure are erased from the memo-
ry. This is to ensure that any lost
or stolen keys can no longer be
used to start the car.
IMPORTANTThe Alfa Romeo CODE
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 sys-
tem is running a self-diagnosis (e.g. due to
a voltage drop). The first time you stop y-
ou can test the system as follows: switch
the engine off by turning the ignition keytoSTOP; 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 de-
scribed previously. If the problem persists,
contact your Authorised Alfa Romeo Dealer.
2) If the warning lamp flashes it means
that the car is not protected by the immo-
biliser. Contact your Authorized Alfa
Romeo Code Dealer immediately and get
them to store the codes of all the keys in
the memory.
If after about 2 seconds
with the key in the
MAR position, the Alfa
Romeo CODE warning light turns
on again flashing at appr. half
second intervals, this means that
the code of the keys has not
been memorised, thus the car is
not protected by the Alfa Romeo
CODE system against attempted
theft. In this case, contact an Au-
thorized Alfa Romeo Service to
have the key codes memorised.

IMPORTANTIn the case of fast start-
ing, turning the key directly from STOP
toAV V, the recognition code might not
be transmitted completely, preventing the
engine from starting: try again more
slowly.
IMPORTANTThe system is protected
by two fuses housed in the main fusebox
(see “If a fuse or relay blows” in the
chapter “In an emergency”).
EMERGENCY STARTING
If it is not possible to deactivate the en-
gine inhibitor with the ignition key, Alfa
Romeo Authorized Services can carry out
the emergency procedures using the code
of the CODE card, or, you may do this
yourself, following the procedure de-
scribed below.
IMPORTANTYou are advised to care-
fully read the entire procedure before car-
rying it out.If a mistake is made during the emer-
gency procedure, the ignition key should
be turned to the STOPposition and the
operations must be repeated from the s-
tart (point 1).
1) Read the 5-figure electronic code on
the CODE card.
2) Turn the ignition key to the MAR
position.
3) Fully depress the accelerator pedal
and keep it pressed. The EOBD/fuel sup-
ply-ignition system failure warning light
will come on for eight seconds ap-
proximately and will then go out; now re-
lease the accelerator pedal.
4) The warning light begins to
flash: after it has flashed for the same
number of times as the first digit on the
code of the card, press completely and
hold down the accelerator pedal until the
warning light comes on (for 4 sec-
onds) and then goes out again; now re-
lease the accelerator pedal.
5) The warning light will begin to
flash: after it has flashed for the same
number of times as the second digit on
the code of the CODE card, press com-
pletely and hold down the accelerator
pedal.

6) Repeat this procedure in the same
way for the other digits on the CODE card
code.
7) After entering the last figure, keep
the accelerator pedal pressed. The warn-
ing light turns on (for four seconds)
and then goes off; now release the accel-
erator pedal.
8) A quick flash of the warning light
(for appr. 4 seconds) confirms that
the operation has taken place correctly.
9) Start the car turning the ignition key
from the MARposition to the AVV po-
sition without returning the key to the
STOPposition.
Conversely, if the warning light
stays on, turn the ignition key to STOP
and repeat the procedure starting from
point 1).
IMPORTANTAfter emergency start-
ing it is advisable to turn to an Alfa
Romeo Authorized Service, because the
procedure described must be repeated
each time the engine is started.

22 ELECTRONIC ALARM
(optional for versions/markets where
applicable)
DESCRIPTION
The system certified in accordance with
EC Directive 95/56 comprises: transmit-
ter , receiver, control unit with siren and
volumetric sensors. The electronic alarm
is controlled by the receiver and it is
turned on and off through the remote
control incorporated in the key which
sends the crypted, variable code. The
electronic alarm monitors: unlawful open-
ing of the doors, bonnet and boot
(perimetral protection), operation of the
ignition key, battery and emergency key
cable cutting, the presence of moving
bodies in the passenger compartment
(volumetric protection) and operates the
central door locking system. Is also
makes it possible to cut off volumetric
protection and/or the siren.
IMPORTANTThe engine inhibitor
function is guaranteed by the Alfa Romeo
CODE system which is activated automati-
cally when the ignition key is removed
from the lock.
REMOTE CONTROL (fig. 11)
The remote control is incorporated in the
key and it is fitted with a button (A) and
a led (B); the button activates the con-
trol, the led flashes while the transmitter
sends the code to the receiver. This code
(rolling code) changes at each transmis-
sion.
IMPORTANTIf, when pressing the
push-button (A), the led (B) issues just a
short flash, replace the batteries as
shown in the previous paragraph.Request for additional remote
controls
The receiver can recognise up to 5 re-
mote controls.
If during the life of the car a new re-
mote control is needed for any reason
whatsoever, contact Alfa Romeo Autho-
rized services directly, taking with you the
CODE card, a personal identity document
and the car’s possession documents.

ACTIVATING THE ALARM
When the doors and boot/bonnet lids
are closed and the ignition key is in the
STOPposition (key removed), point the
remote control towards the car and press
the button on the ignition key.
With the exception of some markets the
system sounds a “BEEP”, the hazard
warning lights turn on for appr. three sec-
onds and the door lock is engaged.
Engagement of the alarm is preceded
by a self-diagnosis characterised by a
change in the frequency at which the led
(A-fig. 12) flashes. If an anomaly is
detected the system gives off a further
“BEEP”.Surveillance
When the system has been turned on,
the led (A-fig. 12) on the dashboard
will flash to indicate that the system is in
the surveillance mode.
The led (A) inside the car flashes
throughout the whole time the vehicle is
under surveillance.
IMPORTANT Operation of the elec-
tronic alarm is adapted at the origin to
the regulations 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 hand, if a door or bon-
net/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-diagno-
sis function has detected a system operat-
ing fault, in which case it is necessary
contact Alfa Romeo Authorized Services.
DEACTIVATING THE ALARM
To deactivate the alarm press the button
on the remote control. The system per-
forms 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.
IMPORTANT If the led in the car s-
tays on when the system has been deac-
tivated, (maximum of 2 minutes or until
the ignition key is moved to MAR) the
following 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
different intervals than normal, it means
that attempts to steal the car have been
made, counting the number of flashes it
is also possible to identify the type of at-
tempt:
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 cables
or cutting emergency key cables
10 flashes: at least three causes of alarm.WHEN THE ALARM IS
TRIGGERED
When the alarm is engaged it will sound
when:
– One of the doors, the bonnet or the
boot is opened.
– The battery is disconnected or the
electric cables are cut, or the emergency
key cables are cut.
– Intrusion into the passenger compart-
ment, e.g. window being broken (volu-
metric protection).
– Attempt to start the engine (key at
MAR).
Depending on the markets, the trigger-
ing of the alarm will activate the siren
and the hazard warning lights (for about
26 seconds). The methods of operation
and the number of cycles may vary de-
pending on the versions/markets. How-
ever a maximum number of cycles is fore-
seen. Once the alarm cycle has come to
an end the system will return to its nor-
mal monitoring state.
SWITCHING OFF THE ALARM
To switch off the alarm, press the re-
mote control button on the key. If the
alarm does not turn off due to a flat re-
mote control battery or system fault,
open the door after unlocking with the
lock key, then place the key in the igni-
tion switch and turn it to MAR.
To turn on the alarm again, turn the key
toSTOPand remove it, then press the
remote control button after leaving the
car and shutting the doors. If the alarm
does not turn on and the led on the re-
mote control gives only one brief flash
while the led on the dashboard stays on
glowing steadily for about 2 minutes, the
key battery should be replaced by a new
one of the equivalent type on sale c/o
normal retailers. To change the battery
follow the instructions given at paragraph
“Key battery change” on previous pages.
If it is not possible to switch on the
alarm with a new remote control battery,
contact Alfa Romeo Authorised Services
to have the system checked.

each country on the subject of radio fre-
quency, we point out that:
– the separate homologation numbers
for each market are given on the last
pages of this handbook before the alpha-
betical index (for some countries also ho-
mologation document);
– for markets in which the transmitter
needs to be marked with the homologa-
tion number, this has been stated on the
component.
(Depending on the versions/markets,
the code may also be marked on the
transmitter and/or on the receiver).

to programme additional remote controls,
contact Alfa Romeo Authorized Services.
IGNITION DEVICE
THE SWITCH (fig. 15)
The switch has four positions:
–STOP: engine switched off, key can
be removed, engine lock engaged, steer-
ing lock engaged, all services excluded a-
part from those powered directly (e.g.
hazard warning light I.C.S. system (ex-
cept climate control).
–ACC: position for using the cigar
lighter and of the I.C.S. system (except
climate control).
–MAR: drive position. The engine
lock is deactivated and all electrical de-
vices are powered.
