how do i change the low fuild and low oil sensors?

It's really simple. Turn the key on but not to start the engine. Make sure the radio is off and hit the "display" button for a couple of seconds, the big knob on the bottom on the left of your radio until the "settings" display shows. Hit the scan button to the right until "Tire pressure" comes up. Hit # 1 on your radio select buttons until it says "reset". Push the "display" button until you hear a "beep". Press the scan button a couple of times until it says "exit" then press "display". After it "beeps" you're all done.
