2004 Buick Rendezvous Question: How do I reset the "change engine oil" light, after changing the oil?
Turn the ignition on and press the accelerator fully down and fully up 3 times within 5 seconds. If oil change message flashes it has been reset. - ProfessorG
On the lower left side of dash is the Driver information center with two buttons. Push and release the left one, mode until you see oil life left. Hold down button on the right (reset) until oil life is back to 100%. - codeWizard
