Many thanks for a quick response and guide. So out with both of the manuals, car and multimedia, but numbering slightly different to your description but it gave me a good place to start and look.
Think I have found the answer, and related to the 'Active Emergency Braking'. I will try some finger pushing, but the manual says 'consult dealer'.
