Unfortunately there's no button to press.
The procedure to reset the change oil message has been posted here a million times and is right there in your owner's manual. 2010's and newer have the manual on a DVD. It can also be downloaded at www.jeep.com
While you check on that, you can reset it by doing the following:
Turn the key to the "on" position without starting th engine. It's the 2nd click. All of you dash warning lights should be on. Press the gas pedal all the way to the floor 3 times. Turn the key to "off".
