Wash function for windscreen and rear window (Touring)

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.

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.
