This is someone else’s top tip from a previous thread which I’ve just successfully tried, having spent years trying to time opening the upper tailgate as the rear wiper blade sweeps past the 6 o’clock position 🙄😂

Said/ below top tip works 👍🏻 found I’d forgotten to change my rear blade last year, as a result of which it was baked on and starting to show signs of knackerage. Out of sight out of mind, always remember to change your rear wiper or you might scratch your rear screen ((fortunately not in our case)...

WIPERS SERVICE POSITION
Before changing a front wiper blade, the wiper
arms must be set in the �service� position as
follows;
Note: The Smart Key must remain in the
vehicle while wiper blades are replaced.
1. Ensure that the ignition is turned off.
2. Turn the ignition on then off again.
3. Immediately push the wiper control down
to start the single wipe operation and turn
on the ignition again.
The wipers will move to their service
position.
4. When the new parts have been fitted, turn
the ignition off. This will return the wipers
to park position.
