Re: Air filter restriction gauge
The yellow band will move toward the air filter under heavier loads. The dirtier the filter the further it will move. It will stay at the furtherest point until reset by pushing in the yellow button on the end. The factory filter should last at least 30k miles under highway conditions. If you want to check the filter minder, you can unplug it, then remove by slowly pulling and twisting it out of the grommet. Then suck on the end, you should be able to draw the indicator all the way to the end fairly easily. Just make sure you reset and plug it back in when you reinstall it.
