These applies to 2002-2010 Models. Probably applies to the 3-5 series, too!
If you do your own minor maintenance, like oil change, filter replacements (air/Cabin Microfilter), etc.
these could come in handy!
With your foot off the brake pedal insert the key and the hit the start/stop button,
then press and hold the trip meter button. After about ten seconds you will see menu
choices in your speedometer, cycle through them using the trip meter button, hold
the button down when you get to the one you want.
Now you will see some choices in the tachometer, using the trip meter button,
ccyle to the choice you want. Re-check the services in the Car data screen
when done to make sure they took.
Good luck!
