Rear window wiper
WARNING: This page is about a different car, the 2004 Volvo S40, 2003 Volvo S40, 2002 Volvo S40, 2001 Volvo S40, and 2000 Volvo S40. However, it is still accessible from the selected car via links, so may be relevant.
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.
