Service key on the display

My friends vehicle (306) is in 137 thousand .. In the last years, the service key warning had appeared in the last years and it was 19,000 km. This month, when I was 13 thousand odd, I looked at it today.

If you hold the km reset bar and turn the ignition to the starter position, the numbers appear from 10 to 0 on the screen and the maintenance km is reset, the key sign disappears.
