Rain Sensor - Alfa Romeo 156 GTA Owner's Manual

"INTELLIGENT WASHING"
(fig. 72)
Pulling the lever towards the steering
wheel (unstable position) operates the wind-
screen washer.
Keeping the lever pulled, with only one
movement it is possible to operate the wash-
er jet and the wiper at the same time; indeed,
the latter comes into action automatically if
the lever is pulled for more than half a sec-
ond.
The wiper stops working a few strokes af-
ter releasing the lever; a further "cleaning
stroke" after a few seconds completes the
wiping operation.

FUNCTION Rain sensor (fig. 73)
The rain sensor (A), is an electronic de-
vice combined with the windscreen wiper
which has the purpose of automatically ad-
justing the number of wipes during inter-
mittent operation, to intensity of the rain.
All the other functions controlled by the
right-hand lever remain unchanged.
The rain sensor is activated automatically
moving the right-hand lever to position (B-
fig. 70) and it has a range of adjustment
that gradually varies between wiper sta-
tionary (no wiping) when the windscreen is
dry, to wiper at first continuous speed (con-
tinuous, slow) with heavy rain.

Turn ring (F-fig. 71) to set the rain sen-
sor sensitivity level:
AUTO = automatic sensitivity setting.
■■
= low sensitivity
■■■
= medium sensitivity
■■■■ = high sensitivity.
Operating the windscreen washer with the
rain sensor activated (lever at position B)
the normal washing cycle is performed at
the end of which the rain sensor resumes its
normal automatic function.
Turning the ignition key to STOP the rain
sensor is deactivated and the next time the
engine is started (MAR position) it will not
be reactivated even if the lever has remained
in position (B). In this case to activate the
rain sensor, simply move the lever to (A)
or (C) and then back to (B).
