I’ve had numerous e-mails regarding how to reset the service indicator on the smart. No, the Scangauge will not do it for you, although I’d like that! LOL.

Here is how you do it:

1. Switch on ignition. (Do not start car.)
2. Select the maintenance indicator (wrench+distance needs to be in the display) within the first 4 seconds. (You need to double-tap the button on the side of the instrument cluster.)
3. Switch off the ignition . (Wrench(s) should remain in the display).
4. Press the button on the side of the instrument cluster again and continue to hold it while you switch the ignition on. (Again - do not start the car.)
5. Continue pressing the button until the service indicator (wrench+distance) is reset.

Oh, please make sure you have actually changed the oil, with the right kind, and not ovefilled it. Cheers.
