AIR RECIRCULATION AND
AQS FUNCTION (AIR
QUALITY SYSTEM)
ON/OFF (for versions/markets,
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.
IMPORTANT The 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.
In certain weather con-
ditions (e.g. outside
temperature
0°C) and with automatic air re-
circulation control on, mist may
form on the windows. In this
case press button v to
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.
