when is the last time you had an oil change? typically the maintenance required (reqd) light is telling you it's time for an oil change. after changing the oil reset the light. how do you reset it right? simple, there are different styles: one of them with the key off press and hold the trip reset button, still holding turn key on wait for light to blink and go out, then let go of button. another if there is a funny looking button with a dimple in it do same thing as above accept use this button instead of tripometer button. i hope that helps.
