I tried this on my 07 Civic Si and it didn't work.
this procedure turns off a 07 civic hybrid, haven't tried it on a SI yet.Sometimes you have to hold it for a while.
put the ignition key into the ignition but do not turn it ON
with one hand, push in and hold in the Trip Reset button at the bottom of your speedometer. this is the button that resets your trip odometer.
continue to hold the trip reset button in as you turn the ignition key ON. you do not have to start the engine.
continue to hold the trip reset button and watch the maintenance required light. after about 10-15 seconds that light should go out. when it does, use your free hand to turn the ignition key OFF
