The 0 1 2 0 is for the trip computer .
To set the intermittent wiper on the car , you do the following . Click the stalk down , the wipers should move once , then click the stalk back up again . Now wait until you want the wipers to wipe again and move the stick down . This sets the intermittent wip speed , just leave the stalk down . I think you have to set it on each trip .
