Hello
This is for the new shape Micra. It's a bit complicated so it's worth printing it off. But no diagnostic equipment is needed.
You should have 3 buttons above the radio either side of the centre display.
Let's call the one on the left of the display 'A'
The one on the right of the display at the bottom 'B'
The one on the right at the top ( above 'B') 'C'
Still with me? It may be useful to get a mate to read the instructions to you whilst you press the buttons.
Switch ignition on.
Press and release 'A'
Press and release 'B' ( to select 'Maintenance')
Press and release 'C'
Press and release 'B' (to select 'Service')
Press and hold 'C' for 20 secs
'SET DISTANCE TO SERVICE' will appear
Press and release 'B' (to select next service)
Press and release 'C'
'DUE IN XXXX MILES' will appear
Press and release 'A' (to return to main menu)
Switch ignition off.
Hope this helps
