Windscreen and rear screen washer functions:  

The front washer function is active when the ignition is switched on and the front washer switch function is actuated at the same time. The wiper speed corresponds to stage 1. Wiper operation begins as soon as the control lever is actuated.  

The rear washer function is active when the ignition is switched on and the rear washer switch function is actuated at the same time. The wiper speed corresponds to stage 1. Wiper operation starts with a delay of approx. 1 second.  

If washer operation is performed while the windscreen and rear wipers are running in synchronisation, the wipers are subsequently synchronised.
