So my partner just completed the A1 service (oil and filter change) on my RDX.. How do we clear the "Service Required Soon" display? I know if can be done without taking it into the dealer? But how, help

 

It's in the owners manual under oil change. It says there is a little button/nub on the shifter that you press to cycle through to the A1 reminder then hold for 15 secs to reset.

Haven't tried this yet, but the the big Oil change thread also probably has this info.
