Wash function for windscreen and rear window (Touring)

The wash function is available after terminal 30B ON.

To operate the windscreen washer, the wiper switch is pulled backwards (towards driver).

Touring: To wash the rear window, the wiper switch must be pushed forwards (away from the driver) (speed 2).

The washer pump is activated for the activation time. If the wiper switch is activated for a very short time (< 300 ms), only the washer pump is activated. If it is actuated for a longer period, the wiper is added with a delay. After the washer pump is switched off, the windscreen is wiped for 3 wipe cycles to wipe the windscreen dry.
