The windshield wiper can only operate when the ignition switch is in the "ON" position (ignition on).
Warning! Since the wiper blades may freeze to the windshield, the wiper drive motor is protected from breakage, overheating and fire by a circuit breaker. The device automatically switches off the wiper (for about 5 minutes). If this happens, move the windshield wiper control lever to the "off" position and stop at the side of the road or the edge of the road to remove snow and ice from the windshield and free the windshield wipers. After 5 minutes, move the windshield wiper control lever to the working position. If the windshield wiper does not resume operation, take precautions and immediately pull over to the side of the road or the edge of the road and stop. Wait for weather conditions to improve before continuing to drive with the windshield wiper inoperative.

Option A (with switch position "INT")
Turn on the cleaner by moving the lever to one of the lower positions:
– switching on the cleaner for one working cycle (non-fixed position);
INT – intermittent operation mode;
1 – continuous mode at low speed;
2 – continuous mode at high speed.
Press the lever up to make the wiper blades complete one working cycle.
Option B (with the switch in the "AUTO" position)
Turn on the cleaner by moving the lever to one of the lower positions:
– switching on the cleaner for one working cycle (non-fixed position);
AUTO – automatic control of the cleaner;
1 – continuous mode at low speed;
2 – continuous mode at high speed.
Press the lever up to make the wiper blades complete one working cycle.
Automatic control of the cleaner
If you set the wiper control lever to the "AUTO" position, the wiper will turn on and off automatically based on the rain sensor signals. The frequency of the wiper strokes depends on the amount of precipitation on the windshield (the cleaner can operate both in intermittent mode and in continuous mode at low or high speed).

Controls for external lighting and signaling devices, windscreen and headlight wipers and washers, and electric rear window heater. The sensitivity of the rain sensor can be changed by rotating the ring regulator on the wiper control lever (Fig. 1.72). From the middle position (corresponds to the normal sensitivity of the sensor) turn the knob toward the (+) mark to increase sensitivity and toward the (–) mark to decrease sensitivity of the sensor.
The automatic wiper control mode may not operate if the temperature of the rain sensor is around -10°C or lower, or around +85°C or higher. If the windshield is coated with a water-repellent compound, the rain sensor may not correctly estimate the amount of precipitation on the glass. This may cause the automatic wiper to malfunction.
If dirt or other foreign substances (for example, ice or road salt particles) stuck to the windshield above the rain sensor, or the windshield is covered with frost, the windshield wiper may turn on automatically. However, if the wiper blades are unable to remove ice, dirt or other foreign matter from the glass, the automatic wiper control mode will turn off. In such cases, it is necessary to turn on the continuous wiper mode by moving the control lever to the first or second detent position, or remove ice, dirt or other foreign matter manually before returning the wiper to the automatic mode.
