To ensure correct operation
of the incipient misting
sensor, stickers (e.g. road
licence holder) must not be applied
in the “control” area between the
sensor and the windscreen. For this
very reason, both the sensor and
the windscreen must always be
kept clean, to avoid accumulation
of dirt or other substances.
WARNING The demisting procedure is
enabled every time the ignition key is turned
to MAR, or pressing the AUTO button.
When this procedure is working it can be
turned off pressing one of the following buttons:
compressor, air recirculation, air distribution,
air flow. This operation inhibits the
incipient misting sensor signal until the AUTO
button is pressed again or the next time the
ignition key is turned to MAR.
On certain versions, the system is integrated
by an anti-pollution sensor that is able
to switch on the inside air recirculation function
automatically, to reduce the unpleasant
smell of polluted air when driving in urban
areas, queues, tunnels, and when the windscreen
wash/wiper is operated (with the
typical smell of spirits).
WARNING The function of the anti-pollution
sensor is subordinate to safety conditions;
therefore disabling the climate control
compressor or at an outside temperature
below 4°C, the sensor is disabled. In any
case, the sensor can be re-enabled pressing
the recirculation button vuntil taking
it to the automatic mode.
The anti-pollution sensor
is placed in the air flow in
front of the combined particle
activated carbon filter and,
therefore, must be protected
against possible compressed air
jets produced by cleaning equipment.
Moreover, the water collected
from the windscreen wipers
should not come into contact with
the sensor: otherwise, the internal
air recirculation function could be
disabled for long periods.
