FAN SPEED
ADJUSTMENT KNOB
(fig. 82-83)
Turning the ring of knob (4), clockwise
or counter-clockwise, increases or decreas-
es the speed of the fan, thus the amount
of air admitted to the passenger compart-
ment; the 16 selectable speeds are shown
on a bar (in steps of 3) up to a maximum
of 6 bars lit:
- maximum fan speed = all bars lit;
- minimum fan speed = one bar lit.
The fan can be cut off (all bars off) only
if the climate control compressor has been
switched off pressing button (14)
√. To
restore automatic fan speed control, after a
manual adjustment, press button (13)
AUTO. Completely turning the ring of knob
(4) counter-clockwise switches the system
off, with the following situation: display (1)
off; display (5) off; centre display (3) with
lit display

IMPORTANTPressing the inside air re-
circulation button (8)
vit is possible to
obtain the inlet of untreated outside air to
the passenger compartment.
To turn the system on again, simply turn
the ring of knob (4) clockwise, or press any
one button, except the inside air re-circula-tion (8) and rearscreen heating (9) but-
tons; this operation restores all the operating
conditions stored previously.IMPORTANTOn leaving the

Pressing button (14)
√enables the turn-
ing on of the climate control compressor.
This condition is shown by the lighting up of
the led on the button itself.
When the climate control compressor is
turned off, the leds on buttons (13)
AUTO
and (14)√go off; automatic inside air re-
circulation control is also excluded (both leds
off on button 8
v) which always stays
off to prevent misting the windows; even
if unadvisable, it is still possible to restore
automatic operation of inside air re-circula-
tion pressing button (8)
v.
With the climate control compressor off, it
is not possible to admit air to the passenger
compartment with a temperature below
the outside temperature; in this case, the
value flashes on the display concerning the
temperature that cannot be reached and the
left led on button (13
AUTO- fig. 86)
goes off.
The switching off of the climate control
compressor remains in storage even when
the engine has been stopped. To restore au-
tomatic control for switching on the climate
control compressor, press button (14)

INSIDE AIR RE-CIRCULATION
ON/OFF BUTTON
v(fig. 87)
Inside air re-circulation is controlled ac-
cording to three operating logics
- automatic control, indicated by the turn-
ing on of the right led on the button;
- forced engagement (inside air re-circula-
tion always on), indicated by the turning on
of the left led on the button (and by the right
led going off at the same time);
- forced switching off (inside air re-circula-
tion always off with air inlet from outside),
indicated by the turning off of both leds.
These operating conditions are obtained
pressing in sequence the inside air re-circu-
lation button (8)
v.
When inside air re-circulation is controlled
automatically by the system, the right ledon the air re-circulation button (8)
v
stays on all the time and the left led shows
the air re-circulation condition:
on= air re-circulation operating;
off= air re-circulation off.
If inside air re-circulation has been turned
on or off manually, the led on button (13)
AUTOturns off.
In automatic operation, inside air re-circu-
lation is turned on automatically when the an-
tipollution sensor detects the presence of pol-
luted air, for example in cities, queues, tun-
nels and operation of the windscreen wash-
er (with the characteristic smell of spirit).

With the outside temper-
ature below 4°C the cli-
mate control compressor is unable
to work. It is therefore unadvis-
able to use the inside air re-circu-
lation feature
vwith low out-
side temperature as the windows
may quickly mist over.
WARNING
Operation of the climate con-
trol compressor is necessary
for cooling and dehumidifying the air;
it is advisable to keep this function
always on, to prevent window mist-
ing problems.

AUTOMATIC OPERATION AUTO
BUTTON
(fig. 88)
Pressing the (13)
AUTObutton the sys-
tem automatically adjusts the amount and
distribution of the air admitted to the pas-
senger compartment, cancelling all the pre-
vious manual adjustments.
This condition is indicated by the lighting
up of both leds on the button itself.
When the right led, on button (13)
AU-
TO, is off, this means that one or more man-
ual operations have been carried out and
therefore automatic control is not complete
(except temperature control which is always
automatic) indicated by the left led on, or
that the system is in the
OFFcondition.

The inside air re-circulation
system makes it possible
to reach the required “heating” or
“cooling” conditions faster. It is
however inadvisable to use it on
rainy/cold days as it would con-
siderably increase the possibility of
the windows misting inside, espe-
cially if the climate control system
is off.
WARNING
In certain weather condi-
tions (e.g.: outside tem-
perature around 0°C) and with au-
tomatic air re-circulation control on,
mist may form on the windows. In
this case press the inside air re-cir-
culation button (8)
v, to switch
off re-circulation (leds on button
off) and if necessary increase the
flow of air to the windscreen.
WARNING
It is advisable to turn on
the inside air re-circulation
system in queues or tunnels to
avoid admitting polluted air from
outside. The prolonged use of this
function should however be avoid-
ed, especially with several persons
on board, to avoid the possibility of
the windows misting inside.

QUICK FRONT WINDOW
DEMISTING/DEFROSTING
BUTTON
(-MAX-DEFfunction)(fig. 89)
Pressing button (7)
-the climate con-
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)
-, the
led on the rearscreen heating button (9)
(and the led on button (14)√turn on;
at the same time the leds on button (8)
vgo off.IMPORTANTIf the engine is not warm
enough, the function will not engage the
predefined fan speed immediately, to limit
the flow to the passenger compartment of
air that is not warm enough to demist the
windows.
When the maximum demisting/defrost-
ing function is on, the only manual opera-
tions possible are manual adjustment of the
fan and switching rearscreen heating off.Pressing one of the following buttons
again: (7)
-, (8)v, (12)MONO,
(13)
AUTOor (14)√the system switch-
es off the maximum demisting/defrosting
function, restoring the operating conditions
of the system prior to turning it on, in ad-
dition to activating the last function required,
if any.

WING MIRROR
AND REARSCREEN
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.

EMISSION REDUCING DEVICES
Trivalent catalytic converter
(catalytic silencer)
The exhaust system is fitted with a cata-
lyst formed of alloys of precious metals; it
is housed in a stainless steel container which
is able to withstand the high operating tem-
peratures.
The catalyst converts the unburnt hydro-
carbons, carbon monoxide and nitric oxide
in the exhaust gas (even in minimal quan-
tity owing to the electronic ignition and in-
jection systems) into non polluting com-
pounds.Lambda sensors
Lambda sensors measure the content of
oxygen present in the exhaust gas. The sig-
nal transmitted by the Lambda sensors is
used by the injection and ignition electron-
ic control unit to adjust the air - fuel mixture.
Anti-evaporation system
As it is impossible, even when the engine
is switched off, to prevent the formation of
fuel vapours, a system has been devised
which traps the vapours in a special acti-
vated carbon container.
When the engine is running these vapours
are withdrawn and sent to combustion.
ENVIRONMENTAL
PROTECTION
The design and construction of the vehi-
cle have not only been developed with the
traditional aspects of performance and safe-
ty in mind, but also take into account the in-
creasingly pressing problems tied to pro-
tecting the environment.
The choice of materials, techniques and
particular parts are the result of work which
has made it possible to drastically reduce
the harmful effects on the environment and
guarantee compliance with the most strin-
gent international regulations.
USE OF NON-TOXIC
MATERIALS
None of the components of the vehicle con-
tain asbestos. The padding and the climate
control system do not contain CFCs which
are held responsible for the destruction of
the ozone layer.
The colouring agents and the corrosion in-
hibitors used on the nuts, screws and bolts
do not contain cadmium or chrome which
could pollute the atmosphere or water tables.
Due to the high tempera-
tures reached during oper-
ation of the catalytic silencer the
vehicle should not be parked over
inflammable materials (paper, fu-
el oils, grass, dry leaves etc.).
WARNING

CORRECT USE OF THE CAR
182
Tyres
Check the pressure of the tyres routinely at
an interval of no more than 4 weeks: if the
pressure is too low consumption levels in-
crease as resistance to rolling is higher. It
should be underscored that in these condi-
tions tyre wear increases and vehicle per-
formance is lower, therefore also its safety.
Useless loads
Never travel with an overload in the boot.
The weight of the vehicle (especially in ur-
ban traffic), and its geometry heavily affect
consumption levels and stability.
Luggage/ski racks
Remove the luggage rack or ski rack from
the roof as soon as they are no longer used.
These accessories lower air penetration and
adversely affect consumption levels. When
needing to carry particularly voluminous ob-
jects, preferably use a trailer.Electric services
Use electric devices only for the amount of
time needed. Rearscreen heating, addition-
al headlights, windscreen wipers and heater
fan need a considerable amount of energy
therefore, increasing the requirement of cur-
rent increases fuel consumption (up to
+25% in the urban cycle).
Climate control system
The climate control system is a further load
bearing heavily on the engine inducing high-
er consumption levels (up to +20% on av-
erage). Outside temperature permitting,
preferably use the air vents.
Aerodynamic items
The use of non-certified aerodynamic items
may adversely affect air drag and con-
sumption levels.DRIVING STYLE
Starting
Do not warm the engine with the car at a
standstill or at idle or high speed: under
these conditions the engine warms up much
more slowly, increasing electrical consump-
tion and emissions. It is therefore advisable
to move off immediately, slowly, avoiding
high speeds. This way the engine will warm
faster.
Pointless manoeuvres
Avoid accelerating when waiting at traffic
lights or before switching off the engine. This
and also double declutching is absolutely
pointless on modern cars and also increase
consumption and pollution.
Gear shifting
As soon as the conditions of the traffic and
road allow, use a higher gear. Using a low
gear to obtain brilliant performance increases
consumption. In the same way improper use
of a high gear increases consumption, emis-
sions and engine wear.
