Hey guys, I have a 2010 Lancer GTS and just did its first oil change on it. I reset the maintenance reminder the way it said to do it in the service manual, but it reset it to 1300km or 6 months. I went to the dealership and asked them how to change it and they said it doesn't work that way, and that I would have to get them to reset it with the scanner. Is this true, or is there a way to set it properly?

Thanks
