Interesting. I've just noted in my manual, under the "Display Messages" section (i.e. error messages) the message:
"Hdlmp cornering Back-up lamp on!" - "The active cornering light is faulty. Another lamp has taken over its function.
I wonder what this is referring to? The ALS system perhaps, which I *do* have? I didn't realise that other lamps could "take over" this feature, though.
