Washing windshield, general
The windshield is kept clean by washing the windshield.

The windshield wiping function comprises the following subfunctions:
^ Washing function sequence
^ Afterwiping function sequence

Washing function sequence
The washing function is activated by pressing the combination switch (S4) down beyond the catch point. The combination switch is read in by the steering column tube module (N80).
The steering column tube module transmits the "wash" request via the interior CAN.
The front passenger SAM control unit (N10/11) receives this request and then actuates the window washer fluid pump (M5/1). During the wash cycle, wiping takes place at the wiper speed set using the combination switch.
A t = 15 s permanent actuation of the windshield washer system pump is regarded to be a "stuck combination switch", whereupon the window washer fluid pump is then switched off. Three after-wipes take place

Afterwiping function sequence
Afterwiping becomes active as soon as the combination switch is no longer activated. The number of after wipe cycles depends on the operation time of the combination switch.
- Actuation time t < 1 s:
A single after wipe occurs.
- Actuation time t > 1 s:
Three afterwipes occur.

Afterwiping is carried out at the wiper speed set at the combination switch.
