The switch has the following operating positions:
- 1 - High beam (after switching on, the blue indicator light is on)
- 2 - Light signal
- 3 - Direction indicators (after switching on, the green indicator light flashes and the relay clicks)
Rapid flashing of the indicator lamp and clicking of the relay serve as a signal of a malfunction of one of the turn signal lamps (when driving with a trailer, the turn signal lamp on the trailer may also malfunction).
Unfixed inclusion of direction indicators
Press the lever lightly, without moving it beyond the point of increased resistance. If you release the switch lever, it will return to its original position by itself.
