Here's what you should do:
1. Check your owner's manual: See if it provides any specific information about the traction control warning light.
2. Have the system diagnosed: Take your Alero to a qualified mechanic or an auto parts store that offers free OBD-II code scanning. The light is indicating a fault code stored in the car's computer. The code will pinpoint the problem, which could be anything from a faulty sensor to a more serious issue.
3. Don't ignore the light: Driving with a malfunctioning traction control system can compromise your safety, especially in slippery conditions.
Simply turning the car off and on won't reset the warning light because it's signaling a fault that needs attention.
