Thank you for your response , but you might not get my point . in Lexus model 2005 up . computer set up Maintenance schedule alert , it pops off on screen when your car hits 5000 miles from the last oil change or 15000 miles from the last filter replacement , it always appears Alert MANTENANCE REQUIRE when you driving , someone told me to take out battery negative for a while and put back , but i don't think it's the right way , i saw once the Lexus mechanic guy clicked on Navigation button??? or mileage reset button??? when i brought my car back because he forgot to reset Alert . I don't want to pay $135 for oil change at dealer but i don't now how to solve that problem . ThangTran
