Resetting mileage on clio cup 200 trip computer - how?

[Lewis.]

As above please, can't seem to figure it out and want to check how many miles I am getting to a tank. Thanks. I tried pressing both buttons at once in the stalk already and it didn't do anything!

Mine is as you say, how the two end stalk buttons in for a few seconds..

Ok it is that, but you have to hold the buttons for about 5 seconds when the mileage is shown on the display, that does it. Thanks my man!
