So I recently started driving a 2004 Grand Prix. Today, it was hot outside and I know that most cars display the temperature, so I was scrolling through the thing that displays the miles on the car and the date/time. I was hitting an "i" button and it took me to a screen where it asked if I wanted to reset my engine oil monitor system. I accidentally clicked yes, because I thought clicking back would get rid of the question but instead it reset the system. What is an engine oil monitor system and did I just mess up my car???
