TRIP COMPUTER
General features
The “Trip computer” displays information (with electronic key fitted into ignition device) relating to the operating status of
the car. This function comprises the “Trip A” concerning the “complete mission” of the car (journey) and “Trip B” concern-
ing the partial mission of the car; this latter function (as shown in fig. 27) is “contained” within the complete mission.
Both functions are resettable (reset - start of new mission).

Values displayed
Average consumption
This value shows the average con-
sumption from the start of the new mis-
sion.
Current consumption
This value shows instant fuel consump-
tion (this value is updated second by
second). If parking the car with engine
on, the display will show “- - - -”.
Average speed
This value shows the car average speed
as a function of the overall time elapsed
since the start of the new mission.
Travel time
This value shows the time elapsed since
the start of the new mission (driving
time).Range
This value shows the distance in km (or
mi) that the car can still cover before
needing fuel, assuming that driving con-
ditions are kept unvaried.
The display will show “- - - -“ in the fol-
lowing cases:
❒value lower than 50 km (30mi);
❒car left parked with engine running
for long.
Travel Distance
This value shows the distance covered
from the start of the new mission.
Each time the battery is connected and
each time a new mission is started (re-
set), the display will show “0.0”.
IMPORTANTLacking information,
Trip computer values are displayed with
“- - - -”. When normal operating condi-
tion is reset, calculation of different units
will restart regularly. Values displayed
before the failure will not be reset. The “Trip A” displays the figures relating
to:
❒Average consumption

CLIMATE CONTROL
(fast cooling)
IMPORTANTThe compressor √can
be enabled only if the ventilation is en-
abled.
Proceed as follows:
❒turn knob Acompletely leftwards;
❒turn knob Cto top speed;
❒turn knob BtoO;
❒press buttons √andv(buttons
leds on).
How to keep the required
cooling
Proceed as follows:
❒turn air recirculation off (if on).
❒turn knob Ato the required temper-
ature;
❒turn the knurled ring Cto the required
fan speed.
LOOKING AFTER THE
SYSTEM
During the winter, the climate control
system
√must be turned on at least
once a month for about ten minutes.
Before summer, have the system
checked at Alfa Romeo Authorized Ser-
vices.
RECIRCULATION
To turn this function on press button
v: the button led will turn on.
This function is particularly useful when
the outside air is heavily polluted (in a
traffic jam, tunnel, etc.) However, it is
better not to use it for long periods, es-
pecially if there are several people in the
car to prevent window misting up.
Do not use the air recirculation function
on rainy/cold days as it would consid-
erably increase the possibility of the win-
dows misting inside.
IMPORTANTThe inside air recircula-
tion system makes it possible to reach
the required (“heating” or “cooling”)
conditions faster.After connecting/dis-
connecting the battery,
wait for 3 minutes at
least before fitting the electronic
key into the ignition device in
order to allow the climate con-
trol system control unit to reset
the positions of the electric ac-
tuators that adjust air temper-
ature and distribution.

AUTOMATIC TWO-/
THREE-ZONE
CLIMATE CONTROL
SYSTEM
(where provided)
DESCRIPTION
The car is fitted with a two-/three-zone
climate control system which makes it
possible to separately adjust the air tem-
perature in the two/three passenger’s
compartment areas to reach the required
comfort.
For top quality temperature control in
the two/three areas of the passenger's
compartment, the system is fitted with
external temperature sensor, passen-
ger's compartment temperature sensor
and two-side sun radiation sensor.
The climate control system automatically
controls and adjusts the following pa-
rameters and functions:
❒air temperature at driver/passengers
vents;
❒fan speed;
❒air distribution at driver/passenger
vents;
❒compressor activation;
❒air recirculation.
The following parameters and functions
can be set or changed manually:
❒required temperature;
❒fan speed;
❒air distribution on seven levels ;
❒compressor on/off;
❒window demisting/defrosting;
❒air recirculation;
❒one-zone function.
The system is fitted with AQS (Air Qual-
ity System) sensor (where provided),
that turns on air recirculation automati-
cally when it detects the presence of out-
side polluted air (for example in queues
and tunnels).
Where provided, the system is integrat-
ed with an anti-misting sensor A-fig. 48
set behind the driving mirror, capable of
“monitoring” a preset internal area of the
windscreen and of intervening automat-
ically to prevent or to reduce window mist-
A0E0091mfig. 48
ing up, also with climate control OFF,
through a proper strategy. This sensor can
be deactivated through any manual sys-
tem control when the strategy is operat-
ing. The sensor is enabled at each start-
up and in any case when the user press-
es one of the AUTO buttons.

POLLEN FILTER/ ACTIVATED
CARBON POLLEN FILTER
According to versions, the car can be fit-
ted with pollen filter or activated carbon
pollen filter (where provided). The filter
has the specific capability of admitting to
the passenger compartment purified air,
free from particles such as dust, pollen,
etc. The filtering action takes place un-
der all air inlet conditions and it is clear-
ly most effective with the windows shut.
Have the conditions of the filter checked
by Alfa Romeo Authorized Services at
least once a year, preferably at the on-
set of summer. If the car is used main-
ly in polluted or dusty areas it should be
checked and if necessary replaced at
shorter intervals than specified in the
Service Schedule (see section “Car
Maintenance”). AQS function (Air Quality
System) (where provided)
The AQS function turns on automatical-
ly air recirculation when it detects the
presence of polluted air (e.g. in queues
and tunnels).
IMPORTANTWith AQS function on,
after a preset time with recirculation on,
the compressor will enable outside air
inlet (for about 1 minute) to change air
inside the passenger compartment, re-
gardless of outside air pollution level.
IMPORTANTThe AQS function is dis-
abled when the outside temperature is
cold to prevent window misting up. To
reactivate this function, press button
v. Led “A” on button vwill
turn on to indicate that the function is
on.
Failure to replace the fil-
ter may considerably re-
duce the effectiveness of
the climate control system up to
blocking the air flow from the
outlets and vents.
In certain weather con-
ditions (e.g. outside
temperature around
0°C) and with automatic air re-
circulation control on, mist may
form on the windows. In this
case press button vto
switch off recirculation and if
necessary press button + to in-
crease the flow of air to the
windscreen.
With the outside tem-
perature below -1°C the
climate control compres-
sor is unable to work. It is
therefore inadvisable to use the
inside air recirculation function
with low outside temperature
as windows may mist over
quickly.

SWITCHING THE CLIMATE
CONTROL SYSTEM OFF
Keep pressed button “–“ until the dis-
play shows OFF.
With climate control system off:
❒the system stores performed opera-
tions;
❒the display is off (OFF wording is dis-
played);
❒air recirculation is active (button led
on);
❒compressor is active;
❒ventilation is off.
To turn the climate control system on
again press button AUTO or any other
button (excluding
(,vand
MONO). Turning the climate control sys-
tem on again, air recirculation will be
again controlled automatically.Pressing button OFF on the rear control
will display the wording OFF on the rear
display and will stop air flow to rear
seats.
ADDITIONAL
HEATER (diesel
versions only)
(where provided)
The car is fitted with an additional heater
that supports the engine during cold or
winter weather to quickly reach a com-
fortable temperature in the passenger
compartment.
The additional heater works with the en-
gine running when the outside temper-
ature is below 20°C and the engine has
not yet reached normal operating tem-
perature. After connecting/dis-
connecting the battery,
wait for 3 minutes at
least before fitting the electronic
key into the ignition device in
order to allow the climate con-
trol system control unit to reset
the positions of the electric ac-
tuators that adjust air temper-
ature and distribution.
