How to reset the dash display so it doesn't say "service oil change necessary"?

On my 2007 IS250 Lexus, I had the oil changed at an express lube, but they were unable to reset the dash board display. It still says to change oil. Anyone know how to reset this? I hope I don't have to take to the dealer. thanksHow to reset the dash display so it doesn't say %26quot;service oil change necessary%26quot;?Check the owners manual, sometimes they hide it in there. You can call your dealer, ask to speak to someone in service and if its a simple process they will usually tell you over the phone. Good luck.How to reset the dash display so it doesn't say %26quot;service oil change necessary%26quot;?Check the owners manual
