Hey everybody! I have a 2004 Deville and recently after I just had the oil changed and transmission fluid changed my dashboard sounds a continuous beeping noise when I start the car. It beeps about 5 times then it stops. Due to the weather in my area I assumed that it was the "Ice Possible" warning but I am in a completely different climate now and it still beeps. Does anyone have a clue what this mysterious dashboard beeping is? The car runs fine and there is no error messages.
