Rain Sensor - Alfa Romeo 159 Owner's Manual

"Smart washing" function
Pulling the lever towards the steering
wheel (unstable position) operates the
windscreen washer.
Keeping the stalk pulled with just one
movement it is possible to operate the
washer jet and the wiper at the same
time; the wiper actually comes into op-
eration automatically when the stalk is
pulled for more than half a second.
The wiper stops working 3 strokes after
releasing the stalk; a further stroke af-
ter about 6 seconds will complete the
wiping operation.

RAIN SENSOR

(where provided)
The rain sensor A-fig. 55, located be-
hind the driving mirror, is an electronic de-
vice combined with the windscreen wiper
which has the purpose of automatically
adjusting the number of wipes to intensi-
ty of the rain. All the other functions con-
trolled by the right-hand stalk remain un-
changed.
The rain sensor is activated automati-
cally moving the right-hand stalk to po-
sition 1-fig. 54 and it has a range of
adjustment that gradually varies be-
tween wiper stationary (no wiping)
when the windscreen is dry, to wiper
at second speed (continuous, medium
wiping) with heavy rain.
Turning the knurled ring A-fig. 54 it
is possible to increase the sensitivity of
the rain sensor, obtaining a quicker
change from stationary (no wiping)
when the windscreen is dry, to first con-
tinuous speed (continuous, slow). A fur-
ther stroke will confirm operation.
Operating the windscreen washer with
A0E0227m the rain sensor activated (stalk at posi-
tion 1-fig. 54) the normal washing
cycle is performed at the end of which
the rain sensor resumes its normal au-
tomatic function.
Removing the electronic key from the
ignition device, the rain sensor is deac-
tivated and the next time the engine is
started it will not be reactivated even if
the stalk has remained in position 1-
fig. 54. In this case to activate the rain
sensor, simply move the stalk to 0 or 2
and then back to 1.
When the rain sensor is reactivated in
this way, the wiper performs one stroke,
even if the windscreen is dry, to indicate
that reactivation has occurred.
