I've been looking for an answer to this for ages, and I suspect some other Renault drivers too who have a digital dash. I do a lot of driving in France and I've been trying to work out for ages how to get my digital dash to go to KPH from MPH. I finally found and got the following to work. This wasn't written by me, so I don't take the credit, but I hope others may find it useful. I am posting here so perhaps one day somebody will google it.
- ensure the ignition is off, so open and close the door if you're already comfortably seated - Don't be tempted to touch the brake or clutch - have the hands-free card in your left hand - press and hold the top computer-control button on the right-hand stalk - immediately insert the card into the slot - then (still with the cc button pressed) press and hold the Start button. - after about 3-5 second the dash will light up with the speedo flashing - but bide your time and keep pressing them buttons. - after another 3-5 seconds the mph will change to kph but it will still flash so keep your digits stiff and disregard the pain - after another 3-5 second the flashing will stop, the speedo will be in kph
