To insert the metallic insert in the key
grip, keep button (B-fig. 6) pressed
and turn the insert on the direction of the
arrow until it clicks into place, then re-
lease the button (B).
To open/close the doors by remote con-
trol, press button (C). On cars fitted with
electronic alarm system, pressing button
(C) also turns the electronic alarm on/off
and the led (D) (where required) flashes
while the transmitter sends the code to
the receiver. This rolling code changes at
each transmission.
IMPORTANTIf led (D) (where re-
quired) flashes only once briefly when
button (C) is pressed, the battery need
changing as described below.Opening the boot
The boot can be opened by remote
control from outside pressing button (E-
fig. 6), also when the electronic alarm
(where fitted) is on.
In this case the alarm disengages the
boot control sensor, the system (with the
exception of versions for certain markets)
sounds two beeps and the direction indi-
cators light up for about three seconds.
When the boot is closed again the con-
trol function is restored, the system (with
the exception of versions for certain mar-
kets) sounds two beeps and the direction
indicators light up for about three sec-
onds.
When button (B) is pres-
sed, take the utmost care
to prevent the metal insert from
causing injury or damage when it
comes out. Button (B) 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
prevent anyone, especially chil-
dren, from holding it and pressing
button (B) inadvertently.

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.

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.

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.
