You have to use a tool to reset the oil indicator. Don't forget to look at the maintenance book to see what else needs to be looked at besides the oil, because I usually change my oil between the recommended intervals but take it to the dealer when the light goes off...and I know they do several things besides change oil and filter.
I googled a tool for you because I couldn't remember the name brand I have seen.. A Reset tool like a Peake R5 or R5-FCX is needed to reset the oil service or inspection service lights after required service.
