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.

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.

DEFROSTING/DEMISTING
BUTTON
(fig. 110)
Pressing button (9)
(turns on
demisting/defrosting of the rearscreen
and, if present, 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
automatically after 20 minutes, or press-
ing 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 engine is started.
IMPORTANTThe system automatical-
ly turns on rearscreen heating 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
summer.
If the car is used mainly in dusty or pol-
luted areas it should be checked and, if
necessary, replaced at shorter intervals.

CAR MAINTENANCE

IMPORTANT
Engine oil
Should prevailing use of the car be under
one of the following specially heavy condi-
tions:
– trailer or caravan towing
– dusty roads
– short distances (less than 7-8 km) re-
peated and with external temperatures be-
low zero
– frequently idling engines or long distance
low speed driving or in case of a long term
inactivity
replace engine oil more frequently than re-
quired on the Scheduled Maintenance Pro-
gramme.IMPORTANT
Diesel filter
The variety of the degree of purity of the
fuel oil in commerce may make it necessary
to change the fuel oil filter more frequently
than stated in the Scheduled Maintenance
Programme. If the engine is “sobbing” it
is a sign that the filter needs changing.IMPORTANT
Air cleaner
Using the car on dusty roads change the
air cleaner more frequently than specified in
the Schedule Maintenance Programme.
For any doubts concerning the intervals be-
tween the engine oil and air cleaner re-
placement in relation to how the car is used,
contact Alfa Romeo Authorised Services.

CAR MAINTENANCE
221
Car maintenance should be
entrusted to Alfa Romeo
Authorised Services. For
routine and minor maintenance op-
erations you wish to carry out
yourself, always make sure you
have the proper equipment, genuine
Alfa Romeo spares and the neces-
sary fluids; do not however carry
out these operations if you have no
experience.IMPORTANT
Pollen filter
If the car is used frequently in dusty or
heavily polluted environments it is advisable
to replace the filtering element more fre-
quently; in particular it should be replaced if
a reduction of the amount of air admitted to
the passenger compartment is noted. IMPORTANT
Battery
It is advisable to check the battery charge,
preferably at the onset of winter, to prevent
the possibility of the electrolyte freezing.
This check should be carried out more fre-
quently if the car is used mainly for short
trips, or if it is fitted with accessories that
permanently absorb electricity even with the
ignition key removed, especially in the case
of after market accessories.
If the car is used in hot climates or partic-
ularly harsh conditions it is wise to check the
level of the battery fluid (electrolyte) more
frequently than specified in the Scheduled
Maintenance Programme.

(diesel versions)
DRAINING CONDENSATION
WATER
The presence of water in
the supply circuit may
cause serious damage to
the entire injection system and
cause irregular running of the en-
gine. If the warning message +
symbol are shown on the recon-
figurable multifunction display con-
tact Alfa Romeo Authorized Ser-
vices as soon as possible to have
the system relieved. If warning in-
dications turn on after refuelling,
water has probably been poured
into the tank: turn the engine off
immediately and contact Alfa
Romeo Authorized Services.
AIR CLEANER
The air cleaner is connected to the tem-
perature and air flow sensors which send
to the control unit the electric signals need-
ed for correct operation of the injection and
ignition system.
It must therefore always be in perfect con-
ditions, to ensure correct operation of the
engine, low consumption and exhaust emis-
sion levels.
If the operations concern-
ing cleaner replacement de-
scribed below are not car-
ried out correctly and with the due
precautions, they may compromise
the travelling safety of the car. You
are recommended to have this op-
eration carried out by Alfa Romeo
Authorised Services.
If the car is habitually
used in dusty areas, the
cleaner should be replaced
at shorter intervals than those
specified in the Programmed Main-
tenance Schedule.
Any attempt to clean the
cleaner may damage it,
leading to serious engine
damage.
