AIR DISTRIBUTION
SELECTION
Front seat Two-zone/
Three-zone configuration
Pressing buttons (front controls)
N/O/˙you can manually choose
one of the 7 possible modes for air dis-
tribution inside the compartment:
˙Flow of air to the dashboard centre
and side outlets (passenger’s body).
O˙Splitting of the air flow between
the vents to the lower part of the
passenger compartment (warmest
air) and the dashboard centre and
side outlets and the rear outlet
(coolest air).
OAir flow towards the front and rear
lower part of the passenger com-
partment. This type of distribution al-
lows heating of the passenger com-
partment in the shortest time by
proper setting of the temperature.
NSplitting of the air flow between
Owindscreen and front side window
demisting/defrosting vents and the
lower part of the passenger com-
partment. This type of air distribu-
tion allows satisfactory heating of
the passenger compartment while
preventing possible misting of the
windows.
NAir flow to the windscreen and front
side window vents to demist or de-
frost them.
N˙Splitting of the air flow between
the central/side dashboard vents,
rear vents and windscreen and
side window defrosting/demisting
vents. This type of air distribution
allows satisfactory ventilation of
the passenger compartment while
preventing possible misting of the
windows. With compressor off, the system will
check whether outside temperature is
higher or lower/same as the set one:
❒if outside temperature is lower than
the set one, the system will operate
regularly also with compressor off;
❒if outside temperature is higher than
the set one, the system will not be
able to keep the required condition,
the set temperature values will then
start to flash on the display.
Temperature detection (compressor off
and outside temperature higher than set
temperature) is activated each time the
electronic key is fitted into the ignition
device.
Operation of the cli-
mate control compres-
sor is necessary for cooling
and dehumidifying the air; it is
advisable to keep this function
always on, to prevent window
misting problems.

AIR RECIRCULATION AND
AQS FUNCTION (AIR
QUALITY SYSTEM)
ON/OFF (where provided)
Inside air recirculation is controlled ac-
cording to the following operating log-
ics:
❒automatic control, indicated by but-
ton led “A”;
❒forced switching on (inside air recir-
culation always on), indicated by the
turning on of the circular led around
the button;
❒forced switching off (air recirculation
always off with air inlet from the out-
side), indicated by the turning off of
the circular led around the button.
With A.Q.S. (air quality sensor - where
provided), the operating logics becomes
sequential by pressing button
v.IMPORTANTThe inside air recircula-
tion system makes it possible to reach
the required heating or cooling condi-
tions 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 control compressor is off.
It is advisable to turn on the inside air
recirculation system in queues or tunnels
to avoid admitting polluted air from out-
side. The prolonged use of this function
should however be avoided, especially
with several persons on board, to avoid
the possibility of the windows misting
inside and to guarantee the required
fresh air inlet.

Anything that modifies its original con-
ditions invalidates its efficiency. Anything
that modifies its original conditions in-
validates its efficiency. If due to unusu-
al natural events (floods, seas storm,
etc.) the device has been affected by
water and mud, it must necessarily be
replaced.PRETENSIONERS
To increase the efficiency of the seat
belts, the car is fitted with front preten-
sioners. These devices, in the event of
a violent crash, rewind the seat belts a
few centimetres. In this way they en-
sure that the seat belt adheres perfect-
ly to the wearer before the restraining
action begins.
Front pretensioners activation is indi-
cated by buckle withdrawal downwards.
IMPORTANTTo obtain the highest
degree of protection from the action of
the pretensioning device, wear the seat
belt keeping it firmly close to the chest
and pelvis.
Front seat pretensioners activate only
if front seat belts are properly fitted in-
to buckles.
A small amount of smoke may be pro-
duced. This smoke is in no way toxic and
presents no fire hazard.
The pretensioner can
only be used once. Af-
ter a collision that has trig-
gered it, have it replaced at Al-
fa Romeo Authorized Services.
Pretensioner validity is indi-
cated on the label inside the
lower glovebox and in the
scheduled service manual. Pre-
tensioners should be replaced
at Alfa Romeo Authorized Ser-
vices as this date approaches.
WARNING
Operations which lead
to knocks, vibrations or
localised heating (over
100°C for a maximum of 6
hours) in the area around the
pretensioners may cause dam-
age or trigger them. These de-
vices are not affected by vibra-
tions caused by irregularities of
the road surface or low obsta-
cles such as kerbs, etc. Contact
Alfa Romeo Authorized Services
for any assistance.
LOAD LIMITERS
To increase passenger’s safety, the front
seat belt reels contain a load limiter
which allows controlled sag in such a
way as to dose the force acting on the
chest and shoulders during the belt re-
straining action in case of front crash.
