A - fan knob and climate control system
compressor button.
B - recirculation control / air intake from
outside knob.
C - air distribution knob:
air flow to central and side
dashboard vents to ventilate the
chest and the face in warm
weather;
distribution between feet area
diffusers (warmest air) and
dashboard diffusers (coolest air);
towards the footwell diffusers. Due
to the natural tendency of heat to
spread upwards, this type of
distribution warms the passenger
compartment up as quickly as
possible, providing an immediate
feeling of warmth;
distribution between footwell
diffusers and windscreen/front
side window vents. This type of
distribution achieves effective
heating of the passenger
compartment and prevents the
windows from misting up;
air flow to the windscreen and
front side window diffusers to
demist or defrost them.
D - heated rear windscreen button.
E - temperature adjustment knob.

Press the knob A fig. 26 to turn the
climate control system on and off.
NOTE Optimal cooling/heating of the
passenger compartment may not
be guaranteed together with
Start&Stop. To prioritise the operation
of the climate control system,
deactivate the Start&Stop function.
NOTE To stop the air flow from the
vents, turn the knob to 0.
IMPORTANT It is advisable to switch
the air recirculation on whilst queueing
or in tunnels to prevent the introduction
of polluted air. However, it is better
not to use the function for long periods,
particularly if there are many people
on board, to prevent the windows from
misting.
AIR RECIRCULATION
(knob B fig. 26)
internal air recirculation
air intake from outside
Use air recirculation for maximum
climate control performance.
To demist the windows, set the
recirculation control to on
IMPORTANT In warm-humid weather
conditions, using cold air on the
windscreen may cause external
condensation, which could limit
visibility.
