U
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 (on some versions the message + sym-
bol are shown 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 the 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, try-
ing to avoid driving conditions that may cause further flashing and contact Alfa Romeo Authorised
Services 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
Turning the key to MARthe warning light on the dial turns on; it should flash only once and
then go off. If, with the ignition key at MAR, the warning light stays on, this indicates a possi-
ble failure: “Alfa Romeo CODE system”.
IMPORTANTThe turning on at the same time of the
UandYwarning lights indicates
a failure of the Alfa Romeo CODE system.
If, with the engine running, the message + symbol are shown on the reconfigurable multifunc-
tion display, contact Alfa Romeo Authorised Services immediately.
Y
If with the engine running, the Ywarning light flashes, on some versions together with the
message + symbol on the reconfigurable multifunction display, this means that the car is not pro-
tected by the engine inhibitor device (see “Alfa Romeo CODE system” in this chapter). Contact
Alfa Romeo Authorised Services to have all the keys memorised.

GLOW PLUGS
Turning the key to MARthe warning light on the reconfigurable multifunction display turns on;
the warning light turns off when the glow plugs have reached the pre-established temperature.
Start the engine as soon as the warning light goes off.
IMPORTANTWith a high environment temperature, the warning light may turn on for an
imperceptible length of time.
WATER IN FUEL OIL FILTER
The message + symbol are shown by the reconfigurable multifunction display when there is
water in the fuel oil filter.
The presence of water in the supply circuit may cause serious dam-
age to the entire injection system and cause irregular engine opera-
tion. If the message + symbol are shown by the reconfigurable multi-
function display, contact Alfa Romeo Authorised Services as soon as possible
to have the system relieved.
GLOW PLUG WARMING FAILURE
The message + symbol are shown by the reconfigurable multifunction display when there is a
failure in the glow plug warming system. Contact Alfa Romeo Authorised Services as soon as pos-
sible to have the fault eliminated.

INERTIAL FUEL CUT-OFF SWITCH
The message on the display is shown when the inertial fuel cut-off switch is triggered, on some
versions together with the warning light.
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.
ENGINE OIL SENSOR FAILURE
The message is shown by the reconfigurable multifunction display when there is a failure to the
engine oil level sensor. Contact Alfa Romeo Authorised Services as soon as possible to have the
fault eliminated.

INEFFICIENT ABS SYSTEM (where fitted)
Turning the ignition key to MARthe warning light on the dial turns on, but it should go off after
approx. 4 seconds.
The warning light turns on (on some versions the message + symbol are shown on the recon-
figurable multifunction 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 advised, particularly in all cases of less than perfect grip. It is also necessary to contact Alfa
Romeo Authorised Services.
The car is fitted with electronic braking distributor (EBD). The turn-
ing on at the same time of the
xand>warning lights on the dial
(on some versions the message + symbol are shown on the reconfig-
urable 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. Driving extremely carefully, immedi-
ately contact Alfa Romeo Authorised Services to have the system checked.
The turning on only of the
>warning light (on some versions the
message + symbol are shown on the reconfigurable multifunction dis-
play) 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 antilock function. In these conditions, the effectiveness
of the EBD may also be reduced. 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 braking, to have the system checked.

WARNING LIGHT FAILURE
This is shown on the reconfigurable multifunction display when a fault is detected to one of the
warning lights indicated.
POSSIBLE PRESENCE OF ICE ON THE ROAD
The symbol √+ message are shown by the reconfigurable multifunction display and the buzzer
sounds, when the outside temperature reaches or falls below 3° C to warn the driver about the pos-
sible presence of ice on the road. The buzzer lasts for 2 seconds while the outside temperature flash-
ing message is displayed for about 10 seconds; after that time, only the symbol
√is displayed until
the temperature goes beyond 6° C or the engine is stopped. If during travelling, after the signal of
possible presence of ice on the road, temperature goes beyond 6° C, the symbol disappears and if
the temperature reaches again 3°C, a new message (with outside temperature flashing) will be dis-
played together with the corresponding symbol
√accompanied by the sound signal.

DEMISTING
AND/OR DEFROSTING THE
WINDSCREEN AND FRONT SIDE
WINDOWS, REARSCREEN AND
WING MIRRORS
(MAX-DEF FUNCTION)(fig. 97)
Proceed as follows:
- turn the ring of the air distribution knob
(3)to the
-symbol.
The climate control activates all the functions
necessary to quicken demisting/defrosting of
the windscreen and side windows with tim-
ing (switching off automatically after 3 min-
utes), as follows:
- switches off air re-circulation, if engaged;
- sets the maximum air temperature;
- 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 max def function is on, the fol-
lowing are on: the led next to the rearscreen
heating button (5)
(.
IMPORTANTIf the engine is not hot
enough, the function does not immediate-
ly engage the pre-established fan speed, to
restrict the inlet of air to the passenger com-
partment that is not warm enough to demist
the windows.
After demisting/defrosting, simply use the
controls to maintain the optimum conditions
of vision and comfort.
IMPORTANTThe hotter the engine the
more effective defrosting will be.IMPORTANTIn cases of heavy damp
and/or rain and/or big differences in tem-
perature between inside the car and outside,
it is advisable to proceed as follows to
demist the windows:
- air re-circulation off, led next to button
(4)
voff;
- pointer of knob (2) at fan second speed
at least;
- pointer of knob (3) on symbol
≤with
the possibility of passing to position
yif
more misting is noted;
To defrost/demist the rearscreen, press
button (5)
(, led next to button on.

HEATING (fig. 98)
To obtain the temperature required, pro-
ceed as follows:
- temperature adjustment knob pointer (1)
on the red sector as required;
- air quantity adjustment knob pointer (2)
on the fan speed required to personalise the
amount of air admitted;
- air distribution knob pointer (3) on the
required position.
To obtain the maximum heating power pro-
ceed as follows:
- knob pointer (1) as far as it will go clock-
wise (maximum temperature red sector);
- knob pointer (2) on maximum fan
speed;
- air distribution knob pointer (3) on the
required position (position
w) is recom-
mended.
IMPORTANTTo be able to obtain sat-
isfactory passenger compartment warming,
the engine should have reached normal op-
erating temperature.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 mentioned func-
tions, is also reduces the concentration of
pollutants.
The filtering action is active in all air inlet
conditions and it is clearly more effective
with the windows closed.
Have the conditions of the filter checked
at least once a year, preferably at the on-
set of summer by Alfa Romeo Authorised
Services.If the car is habitually used in dusty or pol-
luted areas, the filter should be checked and
replaced at shorter intervals than those spec-
ified in the Programmed Maintenance
Schedule.
If the filter is not replaced
the efficiency of the cli-
mate control system may
be seriously compromised up to
blocking the air flow at the outlets
and vents.
