Rear window wiper
The rear window wiper is synchronized with the windshield wipers. It wipes at every other stroke of the windshield wipers if they are controlled by interval wiping. If the windshield wipers are activated continuously the rear window wiper's interval is twice as long as in the above table.
If the windshield wipers are activated (continuously or interval) and reverse gear is engaged, the rear window wiper is automatically activated for two strokes.
An impulse function can be started by briefly activating the washer function.
