I have a question with regards the info button on the steering wheel. Each time that you press it it cycles through the different screens and changes what you see in the middle display. What I have noticed is that it also temporarily changes what you can see in the average fuel display that is usually visible between the rev counter and middle display. When the info switch is pressed the average fuel display changes to show you a small image of the cruise control symbol with the word off. Does anybody have any info on the purpose of this. I cannot find anything in the manual.
