EOBD ENGINE CONTROL SYSTEM FAILURE
In normal conditions, turning the ignition key to MAR, the warning light turns on, but it should
go off when the engine has started. The initial turning on indicates that the warning light is work-
ing properly.
If the warning light stays on or turns on when travelling together with the message + symbol on
the reconfigurable multifunction display:
glowing steadily- means a fault in the supply/ignition system which could cause high emis-
sions at the exhaust, possible lack of performance, poor handling and high consumption levels.
In these conditions it is possible to continue driving without however demanding heavy effort or
high speeds. Prolonged use of the vehicle with the warning light on may cause damage. Contact
Alfa Romeo Authorised Services as soon as possible.
The warning light goes off if the fault disappears, but it is still stored by the system;
flashing- indicates the possibility of damage to catalyst (see “EOBD system” in this chapter).
If the warning light flashes, it is necessary to release the accelerator pedal to lower the speed of
the engine until the warning light stops flashing; continue the journey at moderate speed, trying to
avoid driving conditions that may cause further flashing and contact Alfa Romeo Authorised Ser-
vices as soon as possible.
If, turning the ignition key to MAR, the Uwarning light does not
turn on or if it turns on glowing steadily or flashing when travelling,
contact Alfa Romeo Authorised Services as soon as possible.

ALFA ROMEO CODE SYSTEM
If with the engine running, the message + symbol are shown on the reconfigurable multifunction
display, contact Alfa Romeo Authorised Services immediately.
If with the engine running, the message + symbol are shown on the reconfigurable multifunction
display, this means that the car is not protected by the engine inhibitor device (see “Alfa Romeo
CODE system” in this chapter). Contact Alfa Romeo Authorised Services to have all the keys mem-
orised.
INERTIAL FUEL CUT-OFF SWITCH
The message + symbol on the display are shown when the inertial fuel cut-off switch is triggered.
If after the display of the message the smell of fuel or leaks from the
supply system are noted,do not re-engage the switch to avoid the
risk of fire.

INEFFICIENT ABS SYSTEM
Turning the ignition key to MARthe warning light on the dial lights up, but it should go off after
approx. 4 seconds.
The warning light turns on together with the message + symbol on the reconfigurable multifunc-
tion display, when the system is inefficient. In this case the braking system keeps its effectiveness
unchanged, but without the potential offered by the ABS system. Caution is advisable, particularly
in all cases of less than perfect grip. It is therefore necessary to contact Alfa Romeo Authorised Ser-
vices as soon as possible.
Inefficient EBD electronic braking distributor
x
>
+The car is fitted with electronic braking distributor (EBD). The turning
on at the same time of the xand>warning lights on the dial togeth-
er with the message + symbol on the reconfigurable multifunction display, with
the engine running indicates an EBD system failure; in this case heavy braking
may cause the rear wheels to lock before time, with the possibility of skidding.
Drive extremely carefully to the nearest Alfa Romeo Authorised Service to have
the system checked.
WARNING
The turning on only of the >warning light on the dial together with
the message + symbol on the reconfigurable multifunction display, with
the engine running normally indicates a failure of the ABS system only. In this
case the braking system maintains its effectiveness, without however the an-
tilock function. In these conditions, the effectiveness of the EBD may also be re-
duced, In this case too, you are recommended to contact the nearest Alfa Romeo
Authorised Service immediately, driving in such a way as to avoid sharp brak-
ing, to have the system checked.

AUTOMATIC TWO-ZONE CLIMATE CONTROL SYSTEM
To start the system (fig. 76):
- turn the knob rings to set the required
temperatures (driver’s side - passenger’s
side).
- press the
AUTObutton.
IMPORTANTThe climate control sys-
tem makes it possible to personalise the
temperatures required on the two sides with
a maximum difference of 7°C between the
driver’s side and the passenger’s side.
IMPORTANTThe climate control com-
pressor only works with the engine running
and an outside temperature above 4°C.
For further details about the system and
how to make the best use of it, read the
instructions given in the pages that follow.
A0A0203m
fig. 76
The coolant used for the
climate control system is
R134a which meets cur-
rent regulations and does not harm
the environment in the event of ac-
cidental spillage.
Absolutely avoid the use of oth-
er fluids which are incompatible
with the system components.
GENERAL
The car is fitted with a two-zone climate
control system, controlled by an electronic
control unit which makes it possible to sep-
arately adjust the air temperature on the dri-
ver’s side and on the passenger’s side. To
obtain optimum temperature control in the
two areas of the passenger compartment,
the system has an outside sensor, a pas-
senger compartment sensor and a two-zone
sun ray sensor.
With an outside tempera-
ture below 4°C the climate
control compressor is unable to
work. It is therefore unadvisable
to use the inside air re-circulation
feature
vwith a low outside
temperature as the windows might
mist over quickly.
WARNING

GETTING TO KNOW YOUR CAR
92
Air quality control is also entrusted to a
combined particle and activated carbon fil-
ter. The climate control system automatically
controls and adjusts the following parame-
ters and functions:
– temperature of the air admitted to the
passenger compartment (for the driver’s and
passenger’s side separately)
– fan speed
– air distribution
– inside air re-circulation on/off
– climate control compressor on/off en-
able.
It is possible to change the setting of the
following functions manually:
– fan speed
– air distribution
– inside air re-circulation on/off
– climate control compressor on/off en-
able.
The control of functions not changed man-
ually remains automatic and in any case the
temperature of the air admitted to the pas-
senger compartment is controlled automati-
cally according to the temperatures set on
the driver’s and passenger’s displays.
IMPORTANTManual selections prevail
over automatic ones and remain in storage
until the user decides to resume automatic
control. The settings selected manually are
stored when the engine is switched off and
resumed the next time it is started. To ensure correct opera-
tion of the incipient mist-
ing sensor, stickers must
not be applied (road licence holder,
time card etc.) in the “control”
area between the sensor and the
windscreen. Care should also be
given to cleaning the windscreen
and the actual sensor, avoiding the
accumulation of dust and other sub-
stances.IMPORTANTThe demisting procedure
is enabled each time the ignition key is
turned to MARor pressing the
AUTObut-
ton. When this procedure is working it can
be turned off pressing one of the following
buttons: compressor, air re-circulation, air
flow, air capacity. This operation inhibits the
incipient misting sensor signal until the
AU-
TObutton is pressed again or the next time
the ignition key is turned to MAR.
On certain versions, the system is inte-
grated by an antipollution sensor capable of
automatically switching on inside air re-cir-
culation to lessen the harmful effects of pol-
luted air in cities, queues, tunnels and op-
eration of the windscreen washer (with the
typical smell of spirits).
IMPORTANTThe function of the an-
tipollution sensor is subordinate to safety
conditions; therefore disabling the climate
control compressor or at an outside tem-
perature below 4°C the sensor is disabled.
The sensor can be re-enabled pressing the
re-circulation button
vuntil taking it to
the automatic mode. On some versions the system is integrat-
ed with an incipient misting sensor installed
behind the inside rear-view mirror, capable
of “controlling” a predefined area of the
windscreen inner surface which can auto-
matically act on the system to prevent or re-
duce misting through a series of operations
such as: opening air re-circulation, enabling
the compressor, air flow to the windscreen,
fan speed sufficient for demisting; in the
case of heavy misting, enabling the
MAX-
DEFfunction.

HI function
(highest heating power - fig. 79)
This is turned on setting on the display a
temperature above 32.5°C, and can be ac-
tivated independently from the driver’s or
passenger’s side or both; this setting brings
the system to the “monozone” mode and
is shown on both displays.
This function can be engaged when re-
quiring to heat the passenger compartment
as quickly as possible, exploiting the maxi-
mum potential of the system.
This function uses the maximum temper-
ature of the coolant fluid, while air distribu-
tion and fan speed are controlled according
to the system settings.
This function is unadvisable with
the engine cold to prevent admit-
ting air that is not warm enough to
the passenger compartment.
All manual settings are possible with this
function on.
To switch the system off, simply turn the
ring of knob (2) or (6) of the temperature
set to a value below 32.5°C; the opposite
display will show 32.5°C.

trol automatically activates timed operation
of all the functions needed to quicken
demisting/defrosting of the windscreen and
front side windows, i.e.:
- it turns on the climate control compres-
sor;
- switches off inside air re-circulation, if on
(both leds off);
- sets the maximum air temperature (HI)
on both displays (1) and (5);
- operates the fan at a predefined speed;
- directs the flow of air towards the wind-
screen and front side window vents;
- turns on rearscreen heating and, if pre-
sent, the wing mirror coils.
When the maximum demisting/defrosting
feature is on, the led on button (7)

DEFROSTING/DEMISTING
BUTTON
((fig. 90)
Pressing button (9)
(turns on demist-
ing/defrosting of the rearscreen and, if pre-
sent, the wing mirror coils.
The turning on of this function is shown by
the turning on of the led on the button.
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.
IMPORTANTThe system turns on
rearscreen heating automatically if the tem-
perature is below 3
°C.
IMPORTANTDo not apply stickers on
the inside of the rearscreen over the heat-
ing filaments to avoid damage that might
cause it to stop working properly.
POLLEN FILTER
Have the conditions of the filter checked
by Alfa Romeo Authorised Services at least
once a year, preferably at the onset of sum-
mer.
If the vehicle is used mainly in dusty or pol-
luted areas it should be checked and if nec-
essary replaced, at shorter intervals.
A0A0214m
The 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 of particles such as dust,
pollen, etc.
In addition to the above, it also effective-
ly reduces the concentration of pullutants.
The filtering action takes place under all
air inlet conditions and it is clearly most ef-
fective with the windows shut.The failure to replace the
filter may considerably re-
duce the effectiveness of
the climate control system up to
blocking the air flow from the out-
lets and vents.
