i just changed my oil and the change oil light is still on how do i reset it?

 

if you still have the factory radio you can reset it through that. You can also turn your key to the ON position, then depress the accelerator pedal all the way to the floor 3 times. A lot of the reset procedures are detailed in the owners manual. If you don't have one you can download a copy here:
