SYSTEM
Turning the key to MARthe symbol on
the display shall flash only once and then
go off. If with the ignition key at MAR, the
symbol stays on the display (together wit
the message), this indicates a possible fail-
ure (see “Alfa Romeo CODE system”).
IMPORTANTThe turning on at the
same time of warning light
Uand sym-
bol
Yindicates a failure of the Alfa Romeo
CODE system.
If with the engine running, the display
shows message + symbol, this means that
the car is not protected by the engine im-
mobilising device (see “Alfa Romeo CODE
system” in this section). Contact Alfa Romeo
Authorized Services to have all the keys
memorised.

Glow plug warming
Turning the ignition key to MAR, the dis-
play shows message + symbol. The symbol
will turn off when glow plugs reach the pre-
set temperature. Start the engine immedi-
ately after the symbol turns off.
IMPORTANTWith mild or hot ambient
temperature, warning light stays on for very
short time. flashing- indicates the possibility of dam-
age to the catalyst (see “EOBD system” in
this section). If the light flashes, it is nec-
essary to release the accelerator pedal to
lower the speed of the engine until the warn-
ing light stops flashing; continue the journey
at moderate speed, trying to avoid driving
conditions that may cause further flashing
and contact Alfa Romeo Authorized Services
as soon as possible.

WATER IN DIESEL
FUEL FILTER
(diesel versions)
Message + symbol are displayed when
travelling to indicate that there is water in
the diesel fuel filter.
DIESEL PARTICULATE
FILTER CLOGGED
(diesel versions)
(upon request for
versions/markets
where applicable)
Message + symbol are displayed when the
diesel particulate filter is clogged and the dri-
ving conditions do not enable to activate au-
tomatically the reclaiming procedure.
To enable the cleaning procedure, keep the
car running until the message + symbol turn
off. Glow plug warming failure
Message + symbol are displayed when
there is a failure in the glow plug warming
system. Contact Alfa Romeo Authorized Ser-
vices as soon as possible to have the fault
eliminated.
ch
The presence of water in
the fuel circuit may cause
serious damage to the en-
tire injection system and cause ir-
regular engine operation. If mes-
sage + symbol are displayed on the
reconfigurable multifunction display
contact Alfa Romeo Authorized
Services as soon as possible to
have the system relieved. If the
above indications come on immedi-
ately after refuelling, water has
probably been poured into the
tank: turn the engine off immedi-
ately and contact Alfa Romeo Au-
thorized Services.

INEFFICIENT ABS
SYSTEM (where
provided) (amber)
Turning the ignition key to MARthe warn-
ing light turns on, but it should go off after
few seconds.
The warning light turns on (together with
message + symbol on the display) when the
system is inefficient. In this case the brak-
ing system keeps its effectiveness un-
changed, but without the potential offered
by the ABS system.
Caution is advisable, particularly in all cas-
es of less than perfect grip. It is necessary
to contact Alfa Romeo Authorized Services
as soon as possible.
INEFFICIENT EBD
ELECTRONIC
BRAKING
DISTRIBUTOR (red)
(amber)
The turning on at the same
time of warning lights
xand>(togeth-
er with message + symbol on the 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 with the utmost care to the nearest
Alfa Romeo Authorized Service to have the
system checked.
INERTIAL FUEL
CUT-OFF SWITCH
Message + symbol are displayed when the
inertial fuel cut-off switch is triggered.

POSSIBLE
PRESENCE
OF ICE
ON THE ROAD
The display shows message + symbol √and a buzzer will sound when the outside
temperature reaches or falls below 3°C to
warn the driver of the possible presence of
ice on the road.
The buzzer will sound for approx. 2 sec-
onds whereas the message will stay on the
display for aprrox. 10 seconds then, only
the symbol will stay displayed until tem-
perature exceeds 6°C or until the engine
is switched off.
If when travelling, next to the indication
of possible ice on road, the temperature will
raise above 6° C symbol
√will turn off. If
temperature falls again below 3° C a new

DEMISTING
AND/OR DEFROSTING THE
WINDSCREEN AND FRONT
SIDE WINDOWS, REARSCREEN
AND WING MIRRORS
(MAX-DEF FUNCTION)(fig. 94)
Proceed as follows:
- turn the ring of the air distribution knob
(3) to the
-symbol.
The climate control activates all the func-
tions necessary to quicken demisting/
defrosting of the windscreen and side win-
dows with timing (switching off automati-
cally after 3 minutes), 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 demisting/defrosting func-
tion is on, the led next to the rearscreen
heating button (5)
-will turn on.
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
compartment that is not warm enough to
demist the windows.
After demisting/defrosting, simply use
the controls to maintain the optimum con-
ditions 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 out-
side, 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. 95)
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 person-
alise the amount of air admitted;
- air distribution knob pointer (3) on the
required position.
To obtain the maximum heating power
proceed 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 warm-
ing, the engine should have reached nor-
mal operating temperature. The filter has the specific capability of fil-
tering external air, thus admitting to the
passenger compartment purified air, free
from 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
onset of summer by Alfa Romeo
Authorised Services. If the car is habitually used in dusty or
polluted areas, the filter should be
checked and replaced at shorter intervals
than those specified 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.

AUTOMATIC TWO-ZONE CLIMATE CONTROL SYSTEM
(for versions/markets where applicable)
To start the system (fig. 96):
- 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 side
with a maximum difference of 7°C
between the driver’s side and the passen-
ger’s side.
IMPORTANTThe climate control com-
pressor can only work with the engine run-
ning and external temperature not very
low. With low external tem-
perature the climate con-
trol compressor is unable
to work. It is therefore inadvisable
to use the inside air recirculation
function vwith low outside tem-
perature as windows may mist
over quickly.
For further details about the system and
how to make the best use of it, read the
instructions given in pages that follow.

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.

The air quality control is also entrusted to
a combined particle and activated carbon
filter. The climate control system automat-
ically controls and adjusts the following
parameters 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. The settings of the following functions
can be modified manually:
- fan speed
- air distribution
- inside air re-circulation on/off
- climate control compressor on/off enable.
The control of the functions that have
not been modified manually will always
be automatic and, in any case, the tem-
perature of the air flowing into the pas-
senger compartment is controlled auto-
matically depending on the temperatures
set on the driver’s and passenger’s dis-
plays.IMPORTANTManual selections pre-
vail 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.
