What is the button below the wiper lever of the Audi A4L?

[LaneLynn]

The button below the wiper lever of the Audi A4L is used to adjust the intermittent wiper timing. Here is some information about the automatic intermittent wiper settings: 1. The automatic intermittent wiper setting allows you to adjust the swing frequency, making the wiper speed vary according to the vehicle speed. When the wiper lever is set to the automatic intermittent position, the wiper will adjust its swing frequency based on the vehicle speed. 2. When the rain is not too heavy and the windshield is not densely covered with water, you can set the wiper lever to the low-speed swing position, marked as LO or LOW. When the rain intensifies and the windshield quickly becomes covered with water, significantly impairing visibility, you should switch the wiper to the high-speed swing position, marked as HI or HIGH, to continuously clear water from the windshield.
