Very helpful and totally agree that the so called manual is useless and not sure who the intended "audience" are. Certainly useless indexing for "old school". Have discovered the "proper" manual is called DFOM and can be found on the website alongside the manuals for dummies (but they must be clever dummies to make sense of it!). Shame Lexus do not provide the DFOM in hard copy to new owners as I am sure it would solve many queries.
