whenever ur maintanace light is on...go back to the dealer....maybe there's something need to repair...
it has warranty anywayz...dun worry..
There is another forum on this in this section not that far down, I don't know the link off by hand....
We don't have the "maintance" light on our canadian cars, the poster below you is correct. You're thinking of the CEL (Check Engine Light) that comes on when something has gone wrong with the vehicle, example when your MAF (Mass Air Flow) goes (which happened on my previous car) or the odd time if you get bad gas the light will come on and then go off after the gas is gone....
for the OP this is just your "take your car in for regular maintence" light. My mom's Mercury cougar has this and I had the car for a month on my own once and couldn't for the life of me figure out what it was till I looked it up. I thought something was wrong as well....
If you have your oil changed, instead of going and looking for the other forum, although i suggest it as it has more info, to reset your light all you have to do is turn the car to accessory, put it on Trip A, turn the car off, hold the button in, and turn the car back on. It should reset with 0000 and it should turn the light off.... I could be wrong in reciting that (again check other forum) it should also be in your owners manual! or take it to the dealer they may be able to tell you if you can't find it
