Maint. Required light came on and stayed on. on 2007 Scion tC

Whle driving home the Maint. Required light came on and stayed on. What could cause that to happen?

Asked by for the 2007 Scion tC
That info. is in the owners manual. How many miles since the engine was serviced, oil changed?
I don't have an owners manual. Can you tell me what it says? Thanks
You need to get an owners man. it is a must for any vehicle owner!!
Ok.....I can try to get an owners manual, but in the meantime, can you tell me what it says about the Maint. Required light staying on and what it could mean?
Oil needs to be changed, other maint. issues exist! How long have you owned this vehicle? How many miles since last oil change?
2,000 miles since last oil change. I've owned it since July 2007
See dealer or repair shop!
What a help at all!
I do not have enough time to list the possible reasons this light is on! There is a reset procedure but it is in the owners manual, I dont know ,nor does anyone else, why the light is on. We can guess at it all day long and be wasting time. Try holding the tripodometer button in turn key on do not release button until light flashes, if it remains on get a shop to see why!! If you have owned it since 2007 you surely should have the OWNERS MANUAL, Good luck with your problem.
