Don't know what warning light means

No, my temperature guage is not rising higher than normal. I just had my oil changed last week Monday, and when these lights came on yesterday for the first time we checked both the coolant and oil and both were at proper levels. My vehicle does have 99,300+ miles on it. Two weekends ago I did have my PCM under the dash fixed as it had come unconnected. Since then I did have low oil (it was stupid I meant to check it had been doing a lot of driving back and forth due to moving and just forgot cus I was busy with a million things). Had them change oil and it is fine now.

In receiving another gentleman's response, the warning light looks like a rectangle w/ an arrow pointing down inside the box. And in the box along the bottom is a wave looking thing like for water or something. Above the box is what would look like a button to press or something of that nature.

Is the temperature rising higher than normal? Have you checked your oil and coolant levels? Only check coolant with engine off and cold. Many GM products have had faulty coolant level sensors. If all fluid levels are OK, and the vehicle runs and drives fine, the sensor is very likely the culprit. If you check your coolant and find it is low, or that there is orange-brown sludge or goop accumulated in the radiator or the overflow tank, a coolant system flush and refill with universal coolant is highly recommended. The original coolant is called Dex-Cool, and can turn into sludge and corrode certain components in some circumstances. Be sure to have all coolant removed and replaced with universal antifreeze if a flush is performed. Your local parts store may be able to scan the car for trouble codes, which will help to narrow the possibilities. Is the temperature rising higher than normal?
