(highest cooling power - fig. 100)
This is turned on setting on the display a
temperature below 16.5°C; this setting is
shown on both displays.
This function can be engaged when
requiring to cool the passenger compart-
ment as quickly as possible, exploiting the
maximum potential of the system.
The function cuts off air heating,
engages inside air re-circulation (to pre-
vent admitting hot air to the passenger
compartment) and the climate control
compressor, takes air distribution to
RE
and the fan speed as set by the system.
All manual settings are possible with this
function on.
To switch the function off, simply turn
the ring of knob (2) or (6) of the tem-
perature set on a value above 16.5°C;
the opposite display will show 16.5°C.
Pressing key (13)
AUTOthe display will
show a temperature of 16.5°C and
returns to an operating condition with
automatic temperature adjustment.

FAN SPEED
ADJUSTMENT KNOB
(fig. 102-103)
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

CLIMATE CONTROL
COMPRESSOR ON/OFF
ENABLE BUTTON
(fig. 105)
Pressing button (14)
√enables the
turning on of the climate control compres-
sor. 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-circulation pressing button (8)
v.
With the climate control compressor off,
it is not possible to admit air to the pas-
senger compartment with a temperature
below the outside temperature; in this
case, the value flashes on the display con-
cerning the temperature that cannot be
reached and the left led on button (13
AUTO- fig. 106) goes off.
The switching off of the climate control
compressor remains in storage even when
the engine has been stopped. To restore
automatic control for switching on the cli-
mate control compressor, press button
(14)
√again, the led on the buttonOperation of the climate
control compressor is nec-
essary for cooling and de-
humidifying the air; it is advisable
to keep this function always on, to
prevent window misting problems.

INSIDE AIR RE-CIRCULATION
ON/OFF BUTTON
(fig. 107)
Inside air re-circulartion is controlled
according to three operating logics:
- automatic control, indicated by the
turning on of the right led on the button;
- forced engagement (inside air re-circu-
lation 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-circu-
lation always off with air inlet from out-
side), indicated by the turning off of both
leds.
These operating conditions are obtained
pressing in sequence the inside air re-cir-
culation button (8)
v.
When inside air re-circulation is con-
trolled automatically by the system, the
right led on the air re-circulation button
(8)
vstays 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-cir-
culation is turned automatically when the
antipollution sensor detects the presence
of polluted air, for example in cities,
queues, tunnels and operation of the
windscreen washer (with the typical smell
of spirits). The inside air- re-circula-
tion system makes it pos-
sible to reach the required
“heating” or “cooling” conditions
faster. It is however inadvisable to
use it on rainy/cold days as it
would considerably increase the
possibility of the windows misting
inside, especially if the climate con-
trol system is off.
A0A0212b
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.

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.
AUTOMATIC OPERATION AUTO
BUTTON
(fig. 108)
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
previous manual adjustments.
This condition is indicated by the lighting
up of both leds on the button itself. When the right led, on button (13)
AUTO
is off, this means that one or more manual
operations have been carried out and there-
fore 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. In certain weather condi-
tions (e.g.: outside tem-
perature around 0°C) and
with automatic air re-circulation
control on, mist may form on the
windows. In this case press the in-
side air re-circulation button (8)
v, to switch off re-circulation
(leds on button off) and if neces-
sary increase the flow of air to the
windscreen.

FRONT WINDOWS FAST
DEMISTING/DEFROSTING
(MAX-DEF)FUNCTION(fig. 109)
Pressing button (7)
-the climate con-
trol automatically activates timed opera-
tion 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 but-
ton (8)
v.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.
When the maximum demisting/defrost-
ing function is on, the only manual opera-
tion 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
switches off the maximum demisting/
defrosting function, restoring the operat-
ing conditions of the system prior to turn-
ing it on, in addition to activating the last
function required, if any.

WING MIRROR AND
REARSCREEN
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.
A0A0214b
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 takes place under all
air inlet conditions and it is clearly most
effective with the windows shut.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.

CAR MAINTENANCE
It is however wise to remember that Pro-
grammed Maintenance does not complete-
ly cover all the car’s requirements: also in
the initial period before the 20,000 km ser-
vice coupon and later, between one coupon
and another, ordinary care is still necessary
such as for example routinely checking and
topping up the level of fluids, checking the
tyre pressure, etc...
IMPORTANTThe Programmed Mainte-
nance coupons are specified by the Manu-
facturer. The failure to have them carried out
may invalidate the warranty.
The Programmed Maintenance service is
carried out by all Alfa Romeo Authorised Ser-
vices, at pre-established times.If during each operation, in addition to the
ones programmed, the need arises for fur-
ther replacements or repairs, these may be
carried out only with the explicit agreement
of the customer.
IMPORTANTYou are advised to contact
Alfa Romeo Authorised Services in the event
of any minor operating faults, without wait-
ing for the next service coupon.SCHEDULED
SERVICING
Correct maintenance is determined in en-
suring long car life under the best conditions.
This is why Alfa Romeo has programmed
a series of checks and maintenance opera-
tions every 20,000 km.
IMPORTANTOn versions fitted with re-
configurable multifunction display, at 2000
km from the maintenance deadline, the dis-
play will show “REFER TO SERVICE MANU-
AL” which is shown again turning the igni-
tion key to MAR, every 200 km. For fur-
ther details, see “Service” in the “Recon-
figurable multifunction display”.
