This is to alert you of your 5000 mile oil change interval. It will light up every 5k whether you like it or not
to clear:
1. set your odo to the od position and not the trip position
2. turn car off (remove key)
3. foot on brake pedal
4. hold down the odo button
5. put in the key and turn the car on
6. in about 5-8 seconds it will reset the light and the odo will go all dotted ----------
should be good for another 5k
This is from memory, check your owners manual if for some reason it doesn't work out
