Air recirculation and AQS function
on/off button A

If the AQS sensor is not fitted, air recir-
culation works according to the following
operating logics:
❒ forced switching on (inside air recir-

culation always on), indicated by sym-
bol

í on the display;

❒ forced switching off (air recirculation

always off with air inlet from the out-
side), indicated by symbol êon the

display.

The above operating conditions are ob-
tained by pressing in sequence the air re-
circulation button A.

Due to safety reasons, after long recircu-
lation activation (over 25 minutes), the
system will deactivate automatically air re-
circulation for 60 seconds to enable out-
side air inlet.

IMPORTANT The inside air recirculation
system makes it possible to reach the re-
quired heating or cooling conditions faster.

It is however inadvisable to use it on
rainy/cold days as it would considerably in-
crease the possibility of the windows mist-
ing inside, especially if the climate control
system is off.

When outside temperature is below 3°C,
recirculation is forced to off (outside air
inlet) to prevent window misting up.

It will be reactivated automatically if out-
side temperature becomes higher than 5
°C.
The AQS sensor (Air Quality System) in
addition to the above operating logics, en-
ables to control recirculation automati-
cally according to the quality of outside air:
❒ automatic control indicated by symbol

≥on the display.

In this event the display will show symbol

ïor ñaccording to actual recircu-

lation operating conditions (on or off).

In automatic operation with AQS, inside
air recirculation is turned on automatical-
ly when the antipollution sensor detects

the presence of polluted air, for example
when driving in the city, queues and tun-
nels.

With compressor on, in order to prevent
polluted air (exhaust gas) inlet at stops, the
system will stop air recirculation when the
car speed falls below 6 km/h. As the car
speed increases (over 25 km/h), the sys-
tem will restore the previous automatic
operating conditions.

In automatic operation, AQS is deacti-
vated when outside temperature is below
3°C, the system will activate air recircu-
lation (indicated by symbol

≥on the

display). The user can however set it man-
ually by operating in rolling mode the reir-
culation button: pressing the button for
the first time will display the current re-
circulation condition, indicated by symbol

ê.
It will be reactivated automatically if out-
side temperature becomes higher than 5
°C.

Press the button again to select the re-
quired recirculation condition, indicated
by the corresponding symbol on the dis-
play. Under these conditions manual ac-
tivation of the AQS function could cause
window misting up.

When air recirculation is set manually,
wording FULL will turn off and A will dis-
appear from the recirculation symbol on
the display.

It is inadvisable to use the in-
side air recirculation func-

tion with low outside temperature as
windows may mist over quickly.
