At each start, the rain sensor automatically
stabilises at a temperature of about 40°C
to eliminate any condensation from the con-
trol surface and prevent the formation of ice.
The rain sensor is able to detect and au-
tomatically adapt to the presence of the fol-
lowing particular conditions which require
different sensitivity:
– impurities on the control surface (salt,
dirt, etc.);
– streaks of water caused by worn wiper
blades;
– difference between day and night (the
human eye is more disturbed during the
night by the wet glass surface).
