Attention! Because the wiper blades can freeze to the windshield, the wiper motor is protected from damage, overheating, and fire by a circuit breaker. The device automatically turns off the windshield wiper (for about 5 minutes). If this happens, move the wiper control to the position «turned off» and stop on the side of the road or on the edge of the road to remove snow and ice from the windshield and free the wiper blades. After 5 minutes, move the wiper control lever to the operating position. If the windshield wiper does not restart, take precautions and immediately pull over to the side of the road or driveway and stop. Wait for the weather conditions to improve before driving 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:
- enable the cleaner for one work cycle (non-fixed position);
INT - intermittent operation mode;
1 - constant mode at low speed;
2 - constant mode at high speed.
Push the lever up to make the wiper blades complete one cycle.
Option B (with switch position «AUTO»)
Turn on the cleaner by moving the lever to one of the lower positions:
- enable the cleaner for one work cycle (non-fixed position);
AUTO - automatic control of the cleaner;
1 - constant mode at low speed;
2 - constant mode at high speed.
Push the lever up to make the wiper blades complete one cycle.
Automatic purifier control
If you set the wiper control lever to the position «AUTO», the purifier will turn on and off automatically according to the rain sensor. The frequency of brush strokes depends on the amount of precipitation on the windshield (the purifier can operate both in intermittent mode and in constant mode at low or high speed).
Pic. 1.72. Rain sensor sensitivity control mode: 1 – ring regulator; 2 - rain sensor
Controls for external lighting and signaling devices, glass and headlight cleaners and washers, rear window electric heater. The sensitivity of the rain sensor can be changed by turning the ring on the wiper control lever (pic. 1.72). From the middle position (corresponds to normal sensor sensitivity) turn the knob to the mark (+) to increase the sensitivity and to the mark (–) to decrease the sensitivity of the sensor.
The automatic wiper control 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, the rain sensor may not correctly judge the amount of precipitation on the glass. This can lead to disruption of the normal operation of the wiper in automatic mode.
If dirt or other foreign matter (e.g. ice or road salt particles) stuck to the windshield above the rain sensor, or the windshield is covered with frost, the wiper may automatically turn on. However, if the wiper blades cannot remove ice, dirt or other foreign matter from the glass, the automatic wiper control will turn off. In such cases, it is necessary to operate the wiper continuously by moving the control lever to the first or second detent position, or remove ice, dirt and other foreign matter manually before returning the wiper to automatic mode.
