This is in the owners manual – just keeping here for a quick search when needed:

Before changing a wiper blade, the wiper arms must be set in the service position as follows:

Make sure the vehicle’s ignition is switched off.

Switch the vehicle’s ignition on and then off again.

Immediately press the wash/wipe control to its lowest position, as if to command a single wipe. Hold this position while switching on the vehicle’s ignition again. The wipers move to the service position. See WIPER OPERATION.

When the new parts have been fitted, switch the vehicle’s ignition off. The wipers return to the park position.
