I know it is in the owner's manual. And I have done it twice before. But I don't remember the exact steps. I just done my 3rd oil change and I don't know where I put the manual (I guess is the old age). Thanks in advance.

 

Press the trip meter select/reset pin until you the oil life reminder is displayed
Press and hold the select/reset pin down for approximately 10 seconds until the oil life reminder is blinking
Press and hold the select/reset pin down for another 5 seconds or so until the oil life reminder is reset to 100%
hope it helps =P

 

pg. 248 or 249 in your manual shows you how.
