I have a 2006 GS 300 and in the message cluster display I have "Oil Service required" and a red triangle warning light in the dash. Tha manual says the display should reset if I start the engine with the odometer reset button held down for 7 seconds ....but the warning will not go away. Any ideas anyone?
