Screen wipers and windscreen washers


0 A starting position (screen wipers do not work).

1 Work of screen wipers in the interval mode / the intensity sensor дождя*.

2 Work of screen wipers with normal rate.

3 Work of screen wipers with the increased frequency.

4 Single inclusion of screen wipers.

5 Work of windscreen washers in the automatic mode.

6 The regulator of an interval of inclusion of screen wipers during the work in the interval mode / sensitivity of the sensor of intensity of a rain.

1 Interval mode or sensor of intensity of a rain *

Interval mode

The interval between inclusions can be regulated in steps by the corrugated castor 6 having four provisions. In addition the interval of inclusion is automatically regulated depending on the actual speed of the movement.

Sensor of intensity of a rain

The sensor allows to regulate automatically the frequency of work of screen wipers depending on intensity of a rain or snowfall. It means that at the switched-on sensor you should not care for inclusion and switching off of screen wipers and switching from one mode of their work to another any more. You can concentrate the attention on the road completely. It is especially important under bad weather conditions and promotes bigger traffic safety and increase in convenience of driving.

If screen wipers are included on an interval operating mode, then they react at once if, for example, on a windshield of your car water from under wheels ahead of the going car got.

The infrared radiator directs through optical system light to a windshield surface in such a way that at dry glass this light is reflected completely. The sensor measures intensity of the reflected light.

If glass is covered with water drops, then extent of reflection decreases as infrared light partially passes through glass. Intensity of the reflected light allows to define extent of moistening of a windshield.

Turning on of the sensor

After turn of the ignition key in situation 1 or 2 transfer the lever switch to situation 1. There will be a single operation of screen wipers.

You can leave for a long time the lever switch in situation 1, and then to you will be enough after turn of the ignition key in situation 1
to turn on the sensor of intensity of a rain. For this purpose:

- turn corrugated a castor 6 or
- involve an automatic operating mode of windscreen washers.

The corrugated castor 6 will allow you to regulate sensitivity of the sensor according to your wishes.

At journey of jet washers switch-off the sensor as inadvertent operation of screen wipers can lead to their breakage.

2 Work of screen wipers with normal rate

At a stop of the car there is an automatic switching to an interval operating mode (it does not belong to cars with the sensor of intensity of a rain).

3 Work of screen wipers with the increased frequency

At a car stop screen wipers work with normal rate (it does not belong to cars with the sensor of intensity of a rain).

5 Work of windscreen washers in the automatic mode

Spraying of a windshield the washing liquid is followed by short-term inclusion of screen wipers.

Short-term impact on the lever switch the washing liquid moves on a windshield, but screen wipers do not join.

Washers of headlights *

If devices of lighting of the car are switched on, then at every fifth operation of washers of a windshield in the automatic mode there is an automatic washing of headlights.

In order to avoid deterioration in visibility it is necessary to use washers only if freezing of the washing liquid on a windshield is excluded.
Use special nonfreezing liquid.

In order to avoid damage of the pump of windscreen washers it cannot be included in the absence of liquid in the tank.

Nozzles of windscreen washers

Heating is carried out automatically * if the ignition key is at the same time in situation 2.
