Hey!
I have a RX400H 2007 and I have been trying this trick for several times but no luck so far :(
Could someone please tell me what this means "1. Switch the car off, then switch it on without (ready) light." I'm not sure how to do this since every time I start the car the ready light is already on?
Perhaps I'm just stupid but I would really need to figure this out since where I'm living we have a lot of snow.
Thanks already for your help!
