Service overdue warning

[Nick Warwick]

Hi can anyone tell me how to get rid of this warning?

I have already serviced the car myself.

Thanks
Nick

1. Turn the key to position I
2. Press and hold in the button for the trip meter
3. Turn on the ignition to position II

Service lamp start to flash. Release the button when this does release the trip meter button. You will hear a bong when its done correctly.
