I have a 5th gen and I change the motor oil myself approximately every 3000 miles (give or take). I've done it twice now and just realized that the little Maintenance indicator that goes from Green to Yellow to Red is now at Yellow...What i'm wondering is if this is because I haven't reset it myself and the car is just logging the miles between oil changes or is it detecting something else wrong? Also, how do I reset it back to green?
