Have a 2009 Insignia with a 360 Cummins on a Freightliner chassis. The change air filter message came on the display on the dash and I don't know how to reset it. The books tell nothing. I changed the filter 1000 miles ago but didn't know about the service reminder thing.
Nope just a screen. I wrote the dealer and he just called back. If he's right I scroll down thru the other options until I get to air cleaner and hold the selector to the right for 4 seconds. Your way sounds simplier! Thanks anyway.
