I added oil and added coolant. The temp. gauge stays on c for cold. I do not know what is going on with my vehicle. Can some one give me a guideline or what to check for. Transmission fluid is good. What else should I be checking for?

That means there is a code in your computer. You have to take it somewhere to get the code pulled and it will tell you exactly what is wrong. Many auto part stores will pull the codes for free. Most of the time when this light comes on and the car is still running fine its an oxygen sensor in the exhaust.
