When the vehicle is stopped, the wiper switches to intermittent operation.
As the speed increases, the glass cleaning intervals are shortened.
A high-pressure washer system for all headlights is installed as special equipment. When you turn on the washer and outdoor lighting, each headlight is washed from a separate jet. In this case, each jet extends by 40 mm and operates at a pressure of about 2.5 bar. For better cleaning, the windshield washer water is mixed with detergent concentrate from a separate tank. In combination with the headlight cleaner, the wiper interval can be set continuously from 3 to 30 seconds. When the vehicle stops, the set interval value is doubled.
Caution: If the wiper motor or switch fails, the control circuit automatically disables the intermittent wipe and the first wipe speed.
