Hmmm, I guess I should read all my manuals. I just learned today that the oil level can be read using the key and the odometer! And it works. I knew I was about a quart down, and sure as chit, turn the key to pos 2, wait for the lines to mappear, push the reset button quickly twice and the display tells me I'm down a quart!

So that's a documented trick. Are there any undocumented tricks?
