This device can only work when the ignition key is at MAR. To switch the rear window wiper on, turn the knurled ring from O to . To wash the window push the stalk towards the dashboard. On certain versions the rear window and windscreen wiping strokes are synchronised.

“Smart washing” function

On certain versions, pulling the stalk towards the dashboard, with just one movement it is possible to operate the washer jet and the wiper at the same time; indeed, the latter comes into action automatically if the stalk is pulled for more than half a second. The wiper stops working three strokes after releasing the stalk. On certain versions a further “cleaning stroke”, after a few seconds, completes the wiping operation.
