So I went in for an oil change today. Asked the guy what was up with the light, and he showed me how to turn it off:
- Turn key to Acc
- Hold odometer push-button in
- Turn key to On
- Watch the odometer reading turn to dashes
- Watch the dashes slowly disappear
- When the dashes all go away, and turn to zeroes, release the odometer button
And voila, the light goes out and stays out for another 5000 miles.
I asked if I could somehow change the setting to have the light come on at some arbitrary mileage (like 3500 or 4000, which is when I like to get my oil changed), but he didn't know of any way to get anything but 5000.
Anyway, thought it was cool, and wish it had been in the manual (not that I would have found it by reading it, of course :).
Update: From the comments on blogspot.com: "make sure you're using the main
odometer; not the trip". Indeed, I had just run across this on my last oil
change, when the service person couldn't get it to reset because it was on
trip. When we put it over to main, it worked fine. Thanks, anonymous
