Switch the ignition on but don't start the engine.

There is a button on the end of either the indicator or wiper arm - sorry but I forget which one as I don't do this procedure very often. With the the ignition on, press this button repeatedly until the spanner symbol flashes and the distance to next service appears on the odometer display.

Now press and hold the trip reset button on the dash until the display has flashed 8 times, release the button and the new distance to next service will be displayed.

Turn off the ignition and it's all done.

Turn on the ignition, but don't start the car. On the right stalk there is a toggle switch that hinges up and down, and is used for going through the different features of the display. When the display shows 'Service Due' press and hold the top part of this switch for 10 seconds until the dispaly resets and it shows 30,000km or whatever until next service.
