A look in the handbook reveals that you have to move the wiper blades to a 'service position' to change them. This is done in a quite obvious (not...) way:
1. Turn the ignition on and off.
2. The press the wiper stalk down (as for intermittent wipe) which moves the wipers to vertical on the screen.
3. Do whatever you need to do to the wipers
4. Remember to turn the engine back on and briefly press the wiper stalk down again to return to wipers to the parked position.
There, nice and logical... I'm going to make sure I don't lose the handbook for this car...
