Brochure does mention that Punto has speed sensitive front Intermittent wipers. Same should be for Linea but till now I couldn't find appreciable difference at city speeds.

Today, I noticed one very small yet interesting thing.
There is a switch for selecting the outside rear view mirror to be adjusted electrically(right or left).

Such discoveries should be called EUREKA :up

Hope I'm not being misunderstood. :mrgreen:
I've not re-discovered the switch. Of course, I knew about it. ::V

"I was talking of the illumination of the arrows on that switch that varies with the position of that switch"

How should it behave? Decrease the wiping delay with increase in speed? :confused

The manual does mention about speed sensitivity of Wiper.
See the picture. You have to keep the wiper position on "intermittent" position.

I also think that wiper speed shall be directly proportional to vehicle speed in the intermittent position.
So that wiping delay shall decrease with increase in speed. :confused

Paddleshifter i tried timing the wiper on my way back, here is what i found. Initially wiper was cleaning every 5 seconds but when i crossed 70kmph it reduced to 3 seconds. So as you said wiping speed is directly proportional to speed of vehicle.I might be wrong about time since i wasn't using a watch as i was driving alone.

Great, another unique feature of Punto/Linea. :dancing
Remember how they say "Rain sensing wipers" with pride for Cruze.
Now, it will be our turn to say "Speed sensitive auto wiper intermittent control" :lol:
Looks very technical and impressive.
I'll also try timing them someday when I get the opportunity. I hadn't timed them, just tried to feel some change. Moreover, mine is in run-in period, so changed speed from 40kmph to 60kmph inside the city roads.

I have seen a more sensible feature in Figo where one can set the wait time between two sweeps in the intermittent mode. Wish we had this too. :boxer .

There's a feature available as standard on the European GP. Not sure about the model sold in India

Rain sensor
Preventive safety means being assured of excellent visibility at all times. This is why the Grande Punto offers a rain sensor as standard equipment, because it keeps the windscreen clear even in bad weather. The system is applied in the upper part of the passenger compartment, behind the rear-view mirror, and automatically activates the windscreen wipers, adjusting frequency according to the intensity of the rain. It is activated by moving the right-hand lever of the control stalk to the first position (intermittent). It is based on the principle of the refraction of infrared rays through the glass and the drops of water.

The optical part of the sensor (lens) sends the infrared light to the windscreen. The latter reflects it and sends it back to the sensor. Because the luminous energy sent to the windscreen is constant, the value measured on reception decreases proportionally to the increase in the quantity of water and other impurities on the glass. Changes in the signal are elaborated by the electronic part of the sensor, which activates the appropriate wiper frequency.

Because the wet surface of the windscreen bothers the human eye more at night than during the day, the sensor also regulates the windscreen wiper on the basis of the ambient light. It recognises the streaking caused by worn blades and compensates for the effects of the ageing of the windscreen and the electronic elements. In particular situations it uses special wiping cycles, for example when there are sparse drops of water or other impurities on the windscreen (salt deposits, dirt, etc.).

The sensitivity of the rain sensor can be adjusted using the two-position ring nut on the right lever of the stalk. If the engine is stopped with the system running, it will be automatically deactivated. To start it again, when he restarts the engine, the driver can either turn the lever on the stalk to zero and then return it to the first position, or adjust the sensitivity of the sensor.

To indicate that it has been reactivated, the system gives one pass of the wipers, even if the windscreen is dry. The sensor is activated automatically after the window washer pump is used, for the time necessary to remove the drops on the windscreen.
