Air recirculation and AQS function
on/off button A
If the AQSsensor 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 íon 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 AQSsensor (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 detectsthe 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, AQSis 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 AQSfunction could cause
window misting up.
When air recirculation is set manually,
wording FULLwill 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.

when the symbol is not displayed will re-
sume automatic control of compressor ac-
tivation; this condition is indicated by the
relevant symbol on the display.
When turning the compressor off, the sys-
tem will deactivate air recirculation to pre-
vent window misting up. Although the sys-
tem is able to keep the required temper-
ature, the wording FULLwill disappear
from the display. If the system is no longer
able to keep the required temperature,
temperature value will flash and the word-
ing AUTOwill disappear from the display.
IMPORTANT With the climate control
compressor off, it is not possible to admit
air to the passenger compartment with a
temperature below the outside tempera-
ture; moreover, under certain environ-
mental conditions, windows could mist up
fastly since air is not dehumidified.The switching off of the climate control
compressor remains in storage even when
the engine has been stopped.

Keep the stalk pulled towards the steer-
ing wheel for more than 2 seconds.
AUTOMATIC HEADLIGHTS
SENSOR (daylight sensor)
(where provided)
It detects the changes of the external light
intensity of the car according to the light
sensitivity set: the greater the sensitivity
is, the smaller the amount of external light
necessary to control the switching-on of
the external headlights will be. The day-
light sensor sensitivity can be adjusted by
the “Set-up menu” of the display.

CRUISE CONTROL
(where provided)
It is a device able to support the driver,
with electronic control, which allows dri-
ving at speed over 30 km/h on long and
straight dry roads (e.g.: motorways), at a
desired speed, without pressing the ac-
celerator pedal. Therefore it is not sug-
gested to use this device on extra-urban
roads with traffic. Do not use it in town.
DEVICE ENGAGEMENT fig. 61
Turn knurled ring Ato ON.
The Cruise Control cannot be engaged
in first or reverse gear. It is advisable to
engage it in 4th
or higher gears.
Travelling downhill with the device en-
gaged, the car speed may increase more
than the memorised one.

ing light
Üturns on together with the rel-
evant message on the instrument panel.TO MEMORISE SPEED
Proceed as follows:
❒turn the knurled ring Ato ON and
press the accelerator pedal to the re-
quired speed;
❒move the stalk upwards (+) for at least
one second, then release it. The car
speed is memorised and it is therefore
possible to release the accelerator
pedal.
In the case of need (when overtaking for
instance) acceleration is possible simply
pressing the accelerator pedal: releasing
the accelerator pedal, the car will return
to the speed memorised previously.
TO RESET THE MEMORISED
SPEED
If the device has been disengaged for ex-
ample pressing the brake or clutch pedal,
the memorised speed can be reset as fol-
lows:
❒accelerate gradually until reaching a
speed approaching the one memo-
rised;
❒engage the gear selected at the time of
speed memorising;
❒press the RES Bbutton.
