I haven't inflated my tyres in 7 months. I have no idea exactly how much the pressure is, but judging from the looks, they seem okay.

Does anybody know what is the exact function of the "M" button on the steering of Ford Fiesta?

When I press it, it changes to the next preset radio station, but only up the the 3rd preset. Pressing it when I'm at the 3rd preset will not change the radio to the 4th preset. Instead, it will restart with the 1st preset.

1 -> 2 -> 3 -> 1 -> 2 ...

If I'm at the 4th preset already (by directly pressing the "4" button), I can continuously hit "M" to change all the way to the "0" preset. Another press will change the radio to the 1st preset.

4 -> 5 -> 6 -> 7 -> 8 -> 9 -> 0 -> 1 -> 2 -> 3 -> 1 ...
