ALFA ROMEO CODE
SYSTEM
IN BRIEF
This is an electronic engine locking
system which increases protection
against attempted thefts of the car. It
is automatically activated when the
ignition key is removed.
There is an electronic device in each
key which can identify the signal
emitted, when the engine is started,
from an aerial built into the ignition
switch. The signal, which changes
each time the engine is started, is the
“password” by means of which the
control unit recognises the key and
enables starting.
1)
Operation
Each time the car is started by turning
the ignition key to MAR-ON, the Alfa
Romeo CODE system control unit
sends an acknowledgement code to
the engine management control unit to
deactivate the inhibitor.
The code is sent only if the Alfa Romeo
CODE system control unit has
recognised the code transmitted by the
key.Each time the ignition key is turned to
STOP, the Alfa Romeo CODE system
deactivates the functions of the engine
management control unit.
Irregular operation
If, during starting, the code is not
correctly recognised, the
warning
light (on some versions a message
together with a symbol is shown on the
display) switches on in the instrument
panel.
In this case, turn the key to STOP and
then to MAR-ON; if it is still locked,
try again with the other keys that come
with the car. If it is still not possible to
start the engine, contact an Alfa Romeo
Dealership.
Activation of warning
light while driving
❒If the
warning light (or symbol on
the display) switches on, this means
that the system is running self-
diagnosis (caused, for example, by a
voltage drop).
❒If the
warning light (or symbol on
the display) stays on, contact an Alfa
Romeo Dealership.

ALARM
(for versions/markets, where provided)
ALARM ACTIVATION
The alarm activates in the following
cases:
❒wrongful opening of a door/bonnet/
luggage compartment (perimeter
protection);
❒wrongful operation of the ignition
switch (ignition key turned to
MAR-ON);
❒cutting of the battery cables;
❒movement inside the passenger
compartment (volumetric protection);
❒anomalous lifting/tilting of the car (for
versions/markets, where provided).
Operation of the alarm is indicated by
an acoustic and visual signal (flashing of
the direction indicators for several
seconds). The alarm activation modes
may vary according to the market.
There is a maximum number of
acoustic/visual cycles. When this is
reached the system returns to normal
operation.IMPORTANT The engine locking
function is guaranteed by the Alfa
Romeo CODE, which is automatically
activated when the ignition key is
extracted from the ignition switch.
IMPORTANT The alarm is adapted to
meet requirements in various countries.
SWITCHING ON THE
ALARM
With the doors, bonnet and tailgate
closed and the ignition key either
turned to STOP or removed, point the
key with remote control towards the car
and press and release the
button.
Except for specific markets, the system
emits a visual and acoustic signal and
enables door locking.
A self-diagnosis stage precedes the
switching on of the alarm: in the event
of faults, the system will generate a
further acoustic and/or visual signal
through the LED on the dashboard.
If after the alarm is switched on, a
second acoustic signal is emitted
and/or a visual signal via the LED on
the dashboard, wait about 4 seconds
and switch off the alarm by pressing the
button, check that the doors,
bonnet and luggage compartment are
closed correctly and then reactivate the
system by pressing the
button.If the alarm emits an acoustic signal
even when the doors, bonnet and
luggage compartment are correctly
closed, a fault has occurred in system
operation: in this case, contact an
Alfa Romeo Dealership.
ALARM SELF-ACTIVATION
(for versions/markets, where provided)
If the alarm has not been activated
using the remote control, once about
30 seconds have elapsed from when
the ignition key was turned to STOP
and a door or the tailgate was last
opened and then closed, the alarm
activates automatically.
This is indicated by the LED on the
button A fig. 10 lighting up intermittently
and the indications of activation
described previously.

AUTOMATIC
DEMISTING/DEFROSTING
(MAX-DEF function)
This function activates automatic
demisting/defrosting of: front windows
(windscreen and side windows), heated
nozzles, heated exterior rear view
mirrors.
To activate the function, turn knob E to
the “Defrosting” symbol identified by
the
symbol.
The manual climate control system will
automatically set itself to the following
configuration:
❒the demisting symbol
will turn
from red to orange (to indicate that
the function has been activated);❒the heated rear window (and all
defrosting devices in the car) will be
turned on. The circular LED around
the
button will light up to indicate
that the function has been activated;
❒the air flow will go to maximum
speed (6th);
❒air circulation will be opened, if it was
closed (the circular LED around the
corresponding button will be off);
❒air mixing will go to “maximum heat”;
❒the additional electric heater (for
versions/markets, where provided)
will be turned on;
❒the compressor will be activated (the
circular LED will switch on to indicate
that the AC function is on).
Window demisting
The climate control system is very
useful in preventing the windows from
misting up in the event of high levels
of humidity.
In the event of considerable outside
moisture and/or rain and/or
considerable differences in temperature
inside and outside the passenger
compartment, proceed as follows to
demist the windows:
❒turn knob A to the red section;
25

Position A: Air flow distribution
between centre/side dashboard
vents, rear diffuser and windscreen
and front side window demisting/
defrosting diffusers. This
distribution setting ventilates the
passenger compartment well and
prevents the windows from misting
up.
Position B: Air flow distributed
between footwell diffusers and
windscreen and front side window
defrosting/demisting diffusers.
This distribution setting allows the
passenger compartment to warm
up efficiently and prevents the
windows from misting up.
Position C: Air flow distribution
between footwell diffusers (hotter
air) and centre/side dashboard
diffusers and rear diffuser (cooler
air).
Position D: Automatic
demisting/defrosting activation
(see description in previous
pages).START&STOP
Manual climate control
If the Start&Stop function is activated
(engine off when the car speed is
0 km/h), the system keeps the air flow
selected by the user.
In these conditions, the compartment
cooling and heating cannot be
guaranteed, as the compressor stops
with the engine coolant pump.
The Start&Stop function can be
deactivated to enhance the operation of
the climate control system by pressing
the dedicated button on the
dashboard.
SERVICING
MAINTENANCE
In winter, the climate control system
must be turned on at least once a
month for about 10 minutes.

❒forced deactivation (air recirculation
always off, air drawn in from the
outside): indicated by the LED on
buttons
switching off and text A
on button B off.
Forced activation/deactivation can be
selected by pressing button
.
When the
button is pressed (button
E off), the climate control system
automatically activates internal air
recirculation (LED on
button A
on). It is still possible to activate outside
air recirculation (LED on the button off)
and vice versa, by pressing button
.
The AQS (Air Quality System) function
(for versions/markets, where provided)
cannot be activated when the
button
is pressed (LED on button E off).
AQS (Air Quality System)
function activation
(for versions/markets, where provided)
The AQS function automatically
activates internal air recirculation when
the outside air is polluted (e.g. in traffic
queues and tunnels).IMPORTANT With the AQS function
active, after a preset time interval of the
internal air recirculation system
functioning, the climate control system
enables the intake of outside air for
approximately one minute to change
the air in the passenger compartment.
This takes place regardless of the
pollution level of the outside air.
IMPORTANT The engagement of the
recirculation system makes it possible
to reach the required heating/cooling
conditions faster. It is, however,
inadvisable to use it on rainy/cold days
as it would considerably increase the
possibility of the windows misting
up inside (especially if the climate
control system is off). When the outside
temperature is low, recirculation is
forced off (air drawn in from the outside)
to prevent the windows from misting
up.
In automatic operation, recirculation is
managed automatically by the system
according to outside environmental
conditions.
IMPORTANT It is advisable not to use
the air recirculation function when
the outside temperature is low to
prevent the windows from rapidly
misting up.CLIMATE CONTROL
COMPRESSOR
Press button C to activate/deactivate
the compressor (activation is indicated
by the lit LED on the button). The
system remembers that the
compressor has been switched off,
even after the engine has stopped.
When the compressor is switched off
the system deactivates air recirculation
to prevent the windows from misting
up and deactivates the AQS function
(for versions/markets, where provided).
In this case, although the climate
control system is capable of
maintaining the required temperature,
the AUTO LED switches off. The
temperatures will flash for a few
seconds if the required temperature
cannot be maintained.
To restore automatic control of
compressor engagement, press again
button C or the AUTO button.
With compressor off:
❒if the outside temperature is higher
than the set one, the system will
not be able to satisfy the request.
The temperature values will then flash
on the display for a few seconds to
indicate this;
❒the fan speed can be reset manually.
32
GETTING TO KNOW YOUR CAR

With the compressor on and the engine
running, manual ventilation cannot be
lower than the minimum speed (only
one LED lit).
IMPORTANT With the compressor off,
air cannot be introduced to the
passenger compartment with
a temperature lower than the outside
temperature. Moreover, under certain
environmental conditions, windows
could mist up rapidly since the air is not
dehumidified.
RAPID WINDOW
DEMISTING/DEFROSTING
(MAX-DEF function)
Press the
button to activate (LED
on button on) the windscreen and side
windows demisting/defrosting function.

on automatically the next time the
engine is started.
For versions/markets where provided,
press the
button to activate
demisting/defrosting of exterior rear
view mirrors and heated nozzles (for
versions/markets, where provided).IMPORTANT Do not affix stickers to the
inside of the heated rear window over
the heating filaments, to avoid damage
that might cause them to stop working
properly.
Thermal comfort
windscreen
(for versions/markets, where provided)
Some versions feature a thermal
comfort windscreen which, with the car
exposed to the sun, reduces the
temperature in the passenger
compartment relative to the outside
temperature, thus ensuring greater
comfort.
Humidity sensor
(for versions/markets, where provided)
The humidity sensor helps to prevent
the windows from misting up. For
full functionality, it is advisable to
activate the AUTO function (LED N on).
When the outside temperature is low,
the system could automatically turn the
compressor on and turn air recirculation
off for safer driving.
