I’ve the same car as Perry, we both bought new at much the same time, I’d concur with his advice.
For peace of mind though, I payed no attention to any instructions when I picked mine up from the factory and now that I’ve read that, I realise I have never done it properly since!
This reminded me of a highland day trip in summer when a freak hail storm caught me out, I’d hail stone in my boxer shorts by the time I had the roof on😂
