The car never came with an owners manual. I downloaded the one off the internet but saw nothing about how to test the filter. I will look into it.
Update: I found it and it is plain as day. I was wondering what that plastic knob was on the side of the air box. :-P. I have no worries, it is on the 1st mark inside the green. I started the car and hit the reset button, and that is where the indicator lies.
