How do you reset the service indicator on a 1998 Mercedes e240?

Mercedes Benz E240 2000 reset service indicator (15000 miles)

First you need to turn the key to #2 position,

Second, you need to push the "0" button on the odometer panel twice,

And then, you turn the key to #0 position means switch off (do not pull the key out)

Fourth, push "0" button at the odometer panel again, whilst holding the "0" button, turn the key to #2 position and count till 14 seconds and the screen will displays 15000 miles to service something like that..I've tried so many times and its works thank god for the luck…

Repeat this step for 4 times
