Button for fast windscreen
MAX
demisting/defrosting
(10 - fig. 102)
Press this button: the climate control
system will automatically (for ap-
proximately 180 seconds) switch on
all the functions required for fast
windscreen and side window demist-
ing/defrosting regardless of the sys-
tem operation conditions, that is:
– climate control system compressor
on (where fitted)
– air recirculation off (if on)
– maximum air temperature (HI) on
both displays
– maximum fan speed
– air flow directed to the windscreen
and front side window vents
– heated rear window and external
rearview mirrors on.
The LED on the heated rear window
button and the amber LED on the air
recirculation button will come on
when the fast demisting/defrosting
function is on. The ECON, AUTO
and OFF LEDS, on the other hand,
will go out.
IMPORTANT If the engine is not
adequately warm, the fan will not im-
mediately be started at top speed to
limit letting cold air into the passen-
ger compartment for demisting the
windows.
Only the fan speed can be adjusted
and the heated rear window can be
switched off when the fast demist-
ing/defrosting function is on.
Press the fast demisting/defrosting
button again or the air circulation
button, ECON, AUTO or OFF to
switch the fast demisting/defrosting
function off and reset the previous
system operation conditions as well as
the last set function.
On certain versions the system is
completed by a sensor fog fitted be-
hind the driving mirror and able to
monitor a section of the windscreen
internal surface and to operate the
system automatically to prevent or to
remove inside fogging from wind-
screen and front side windows
through the following operations: air
recirculation opening, compressor ac-
tivation, air distribution to wind-
screen, fan speed sufficient for defog-
ging and - function activation
MAX DEF
in case of hard fogging.
To guarantee sensor fog
proper operation, license
tag, parking disc or labels
shall not be stuck on the "moni-
toring" area between sensor and
windscreen. Keep sensor and
windscreen clean, preventing any
accumulation of dust or other sub-
stances.
IMPORTANT Defogging procedure
is activated by turning the ignition
key to MAR or depressing the AUTO
button. This procedure can be deac-
tivated by depressing the following
buttons: compressor, air recirculation,
distribution, air flow. This operation
inhibits the sensor signal as long as
the AUTO button is pressed again or,
under some conditions, the ignition
key is turned to MAR again.
