it will come on every 7500 miles to inform you its time for regular scheduled maintnace.. its not a warning, its nothing to worry about. its just programed into the ECU for the stunads who dont know anything about cars.
your owners manual will tell you how to reset it. (if you dont reset it, in another thousand miles or so it will stay on til you reset it)
The light doesn't stay on, it just blinks for about 5 seconds on a cold startup. I'm due for an oil change, belts, water pump and trans fluid anyway - $$$$$
it actually turned on for my odyssey also. i went to autozone to get a reading code, somehow it says o2 sensor is bad. when i brought it to the shop, he just said it's just time to get the car check-up. haha
DOn't confuse the Maintaince light with the Check Engine Light

The other light on the right side of the CEL is the maint. Req light
