I'm having trouble in accessing the display settings.

It's my wife's new company car and we want to turn the km/h display at the bottom.

The manual says you access the settings by pressing the button on the bottom of the stalk and then the end rocker button for 4 seconds or something like that, I don't have the manual with me.

I've tried various combinations but it just keeps rotating around the trip settings.

Please help?

Thanks
