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.

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”).

mark (dot) of the cut to the UNLOCKpo-
sition (2);
– working on the notch (C) remove the
battery holder (D);
– change the battery (E) putting it in the
position shown on the holder;
– insert the holder back in the key and
lock it, turning the reference mark of the pin
(B) to the LOCKposition (1).
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.

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.

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.

CHILD SAFETY LOCK The rear doors are equipped with a special
device (fig. 18) which prevents the door
being opened from inside.
WARNINGEach device only acts on the
door on which it is installed.
The device can only be engaged with the
doors open, raising or lowering the control
with the ignition key:
position 1(control up) – device engaged
(door locked);
position 2(control down) – device re-
leased (door can be opened from inside).
fig. 18
A0B0027m
By pressing the knob (B-fig. 17) on one
of the rear doors only that particular door
will be locked.
WARNINGFor the front doors it is not
possible to keep the knob (B-fig. 16)
down if the door has not been shut properly.
WARNINGThe centralized locking sys-
tem can be deactivated, thus unlocking all
doors, by lifting the door opening lever on
one of the two front doors.
If the power supply is interrupted (burnt
fuse, battery disconnected, etc.) each door
can be opened manually from both inside
and outside the car.
WARNINGThe intervention of the in-
ertial fuel cut-off switch causes the automatic
door unlock and inhibits door locking for
about 30 seconds. After this time, door lock-
ing control unit operation is restored.
Always use this device
when carrying children.
WARNING
After activating the safety
device check that it is
working correctly by pulling on the
inner lever used to open the door.
WARNING

GETTING TO KNOW YOUR CAR62
REV COUNTERThe rev. counter shows engine rpm. The
needle pointed to the danger area (red) in-
dicates excessive high engine speed. Do not
drive for long periods with the needle in this
area.
WARNINGThe electronic injection con-
trol system gradually shuts off the flow of
fuel when the engine is “over-revving” re-
sulting in a gradual loss of engine power.
The rev counter may, when the engine is
idling, indicate gradual or sudden increase
of engine revs as the case may be; such be-
haviour is normal and must not be inter-
preted as a faulty condition as it occurs dur-
ing normal operation, for instance when
climate control or electric fan are switched
on. In particular, slow revs variation helps
keep the battery charged.
FUEL GAUGE AND RESERVE
WARNING LIGHTThis shows the amount of fuel left in the
fuel tank.
This warning light
ç
comes on to indicate
that approximately 7 litres of fuel are left in
the tank.
WARNINGUnder certain conditions
(heavy slopes, for instance), the reading on
the gauge may differ from the actual
amount of fuel in the tank and changes in
level may be indicated late.
This condition falls within the operation log-
ics of the electronic control circuit to avoid
highly unstable readings due to swaying of
the fuel when travelling.
WARNINGRefuelling shall always be
performed with engine off and ignition key
to STOP. If the engine is off but the key
is to MAR, a wrong fuel level could tem-
porarily be indicated. This is due to the in-
ternal system control logic and cannot be
considered as a system malfunctioning.
ENGINE COOLANT
TEMPERATURE GAUGE AND
MAXIMUM TEMPERATURE
WARNING LIGHTThis shows the temperature of the engine
coolant fluid and begins when the fluid tem-
perature exceeds approx. 50°C.
The pointer should normally be towards
the middle of the scale. If the pointer
reaches the higher temperature values of
the scale (red area), the request for vehi-
cle performance should be decreased.
The illumination of the warning light
ç
(together with the message shown by the
Infocenter display) indicates an excessive
temperature of the engine cooling fluid. In
this case, stop the car and contact Alfa
Romeo Authorized Services.
WARNINGThe temperature of the en-
gine coolant may rise towards the maximum
values (red) when the vehicle is driven at
low speeds, especially when the ambient air
temperature is high. In this case, the vehi-
cle should be stopped and the engine
switched off for a few minutes after which
the journey can be resumed, preferably at
a higher speed.

This function is timed and switches off au-
tomatically after 20 minutes, or pressing the
button again; the function is also switched
off when the engine is stopped and will not
be switched on again the next time the en-
gine is started.
WARNINGThe system turns on
rearscreen heating automatically if the tem-
perature is below 3°C.
WARNINGDo not apply stickers on the
inside of the rearscreen over the heating fil-
aments to avoid damage that might cause
it to stop working properly.
WARNINGWhen reconnecting the neg-
ative battery cable after having disconnected
it, wait for 2 minutes before turning the key
to enable the climate control system to re-
set actuator strokes properly.
POLLEN FILTER This filter has the specific capability of com-
bining the mechanical filtering of the air with
an electrostatic effect so that the outside air
admitted to the passenger compartment is
purified and free from particles such as dust,
pollen, etc.
In addition to the above, it also effectively
reduces the concentration of pollutants.
The filtering action takes place under all
air inlet conditions and it is clearly most ef-
fective with the windows shut.
Have the conditions of the filter checked by
Alfa Romeo Authorized Services at least once
a year, preferably on the onset of summer.If the vehicle is used mainly in polluted
or dusty areas it should be checked and if
necessary replaced, at shorter intervals.
Failure to replace the fil-
ter may considerably re-
duce the effectiveness of
the climate control system up to
blocking the air flow from the out-
lets and vents.
