Answer:
1) Ensure ignition key is turned off.
2) press and hold the odometer reset button whilst turning the ignition switch to the on position.
3) Keep the odometer reset button pressed for 10 seconds whilst the service display counts down from 10 to 0. When the count down reaches zero the spanner icon will vanish from the display and the service indicator will be reset.
Should work that's what one of my friends tried and it worked for him let me know if it does.
