This switch operates when the ignition key is in the "ON" or "ACC" (Accessory) position. To operate the rear window wipers and washer, turn the knob at the end of the lever.
Intermittent mode. The brush will make several movements in a row and then work at intervals of approximately 8 seconds.
The windshield wiper is off.
Washing fluid will be supplied to the rear window when the handle is turned all the way in any direction. Simultaneously with the supply of washing fluid, the windshield wiper will automatically operate several times.
Note: To ensure good visibility through the rear window, the wiper blade will make several strokes in succession when shifting to the "–" position, and also when shifting the gearshift lever (manual transmission) or the automatic transmission selector (automatic transmission) to the "R" position if the wiper stalk is in the "–" position. The wiper blade will then automatically switch to intermittent operation.
Precautions when using windshield wipers and washers
If the wiper arms become blocked due to ice or dirt on the glass, the wiper motor may burn out, even if the switch is in the "OFF" position. If the wipers become blocked, stop the car in a safe place, turn off the ignition and clean the glass from dirt and ice so that the wipers can move freely.
Do not turn on the windshield wipers when the glass is dry. This may cause scratches on the glass and premature wear of the blades.
Before turning on the windshield wipers in cold weather, check whether the blades are frozen to the glass. Turning on the windshield wipers with frozen blades can cause the electric motor winding to burn out.
Try not to turn on the washers for more than 20 seconds of continuous operation. Do not turn on the washer when there is no fluid in the washer reservoir. This may damage the washer pump.
Check the level of the washing fluid in the reservoir regularly and top it up if necessary. In cold weather, be sure to add non-freezing windshield washer fluid in the recommended concentration to the reservoir. Otherwise, the washer will not work and system components may fail due to freezing of the washing fluid.
